Content: Greetings everyone. I've started to write a little story and I thought I'd share it with you. So far, I've written eight chapters, but I don't want to post all of them at once. As my gf/mommy has parental control on all my devices, I can only access the story forum during the weekends, so if anyone actually wants to read a new chapter, you can probably expect me to post it somewhere in between Friday and Sunday.

Disclaimer: I've written this story myself. However, I think it's still worth mentioning that English isn't my first language and thus, I sometimes used AI to translate phrases that I couldn't translate by myself. The story however is still written by me, only small parts of the translation were done by AI.
(also, I've just realised that the story takes quite some time to get going. Sorry for that, but that's the way it came to me and I usually just start writing without thinking about things like this too much.

Chapter 1
"Lily," her mother Maria called from the kitchen, "It's past Sarah's bedtime and I'm busy, can you please diaper her and put her to bed?"
Lily let out a sigh of annoyance before replying: "Yeah, just give me a minute please."
She was busy watching her favourite TV show and didn't feel like missing anything, so she planned to wait for the next commercial break to go over to her little sister Sarah's room. The five-year-old girl still didn't manage to stay dry at night, so either their mother or Lily as her older sister put a diaper on her every evening before she went to bed. Lily herself was fifteen years old, even though she was, much to her annoyance, rather small for her age.
Their father André had left the family when Maria fell pregnant with Sarah. Lily could still remember the huge argument they had. While their mother didn't even consider this an option, their father tried to force her to terminate the pregnancy, as he didn't want another child and was of the opinion that they wouldn't be able to afford to raise one.
After this argument, Maria kicked André out of the house and filed for divorce. A couple of months later, she gave birth to Sarah. The first few months were rough, both due to the crying baby in the house and the fact that the small family had almost no money, but after a couple of court dates, André was forced to pay child support for both Lily and Sarah. This bettered their situation by a lot, and Lily, who had never been particularly close to her father, started to like her new life.
When her mother was at work, she took care of Sarah. While at first, she was annoyed by the level of noise and the amount of dirty diapers that her baby sister had brought with her, she grew to love her deeply over the months and years.
Then, when Sarah had just turned three, their mother struck gold. In what little free time she had, she had written a book about her experience as a single mother who had left her husband by choice and how she coped with everything. She sent it out to a couple of publishers and when she eventually found one that would publish it, it became a nationwide bestseller.
From then on, their life got much easier. Maria didn't have to go to work on a daily basis anymore, leading to her having more time for both her daughters. Rather, she kept writing her second book while the little family lived of the royalties of the first book combined with the child support money from the girl's father. The amount of babysitting and diaper changing Lily had to do decreased by a lot due to her mother always being at home and Sarah becoming daytime potty trained.
However, from time to time, Lily still had to help her little sister put on her overnight diaper, as Sarah didn't quite manage to do it by herself yet. They had tried to put her in pull ups, but that just led to leaks and wet bedsheets, so they went back to normal diapers. Lily usually didn't mind when she had to do this, unless she had to interrupt whatever she was doing.
Now, while she sat in front of her TV, waiting for the next break, her mother entered her room, her hands full of dough.
"Lily," she said, sounding annoyed, "I told you to put Sarah to bed, didn't I?"
"But mum," Lily replied, "I'm watching my favourite show. I'm just waiting for the next run of commercials to put her to bed."
Her mother raised her brows and said: "I believe we talked about this more than once, didn't we? Just put her to bed now, it's well past her bedtime already. Unless you want to have your TV privileges taken away for a week."
"Alright," Lily responded and got off the couch angrily, "I'll do it. You go back to whatever important thing you were doing."
"It's actually very important. I'm baking a cake for the fundraiser at Sarah's daycare tomorrow. Don't you remember? It's this weekend," her mother said.
"Oh, I almost forgot," Lily replied, "I'm sorry mum. Go back to the kitchen and continue with your cake. I'll take care of Sarah."
Her mother thanked her and they both left the room. While her mother turned right to go back to the kitchen, Lily turned left to get to her little sister's room. She walked down the hall and entered Sarah's room.
"Well, if you aren't the cutest little girl in the world," she said as she entered and saw her little sister sitting on the floor, playing with her stuffed animals, "But I'm afraid it's time for you to go to bed now. Please don't make It more difficult for me then necessary, okay? I'm in a hurry, I want to continue watching TV."
Much to Lily's delight, her little sister nodded and got up from the carpet. Lily picked her up and sat her down on the changing table, noticing that Sarah was almost too big for it after her recent growth spurt.
She smiled at her little sister and asked: "Did you brush your teeth already?"
As a response, Sarah blew a fresh, minty breath into Lily's face.
"Well done," Lily said, "Then let's get you ready for the night and tuck you in."
Sarah nodded while Lily pulled her pyjama pants down and signalled her do lay down on her back. Then, Lily took a fresh Pampers Premium Protection out of the basket where Sarah's diapers were kept. She noticed that the designs were different than the last time, but didn't care too much about it. These designs were changing all the time and it wasn't really important to her. Meanwhile her sister, knowing what was to come, raised her bottom so Lily could slide the diaper underneath it. Lily folded the diaper open and did just that before pulling the diaper between her sister's legs and taping it shut. While she applied the tapes to the front of the diaper, she noticed the reason for the change in design. The number on the front of the diaper that indicated the size was a 7 rather than a 6 like it was before.
"All done," she told her little sister, who jumped off the changing table with her pyjama pants still around her ankles.
Once she had landed, Sarah pulled up her pants, pulled back the blanket from her bed and laid down, waiting for her big sister to tuck her in. Lily did so, fluffed the blanket and made sure to cover her sister with it, who giggled and hid underneath it as soon as Lily was done.
Lily couldn't help but smile and also giggle as she watched this. Then, she said: "You're getting quite big, aren't you, Sarah? You're wearing size 7 diapers now."
"Yes," her sister responded and peaked out of the her hiding place underneath the blanket, "I'm getting sooooo big."
She put her arms as far apart as possible to emphasize what she was saying to her older sister.
"You sure are. Good night, Sarah. Love you," Lily responded.
"Good night, Lily. Love you, too," Sarah replied.
Lily turned off the light, left Sarah's room and looked at her watch. It had only taken her about four minutes to tuck her little sister into bed, so she hopefully didn't miss too much of her favourite show.
She went back to her room and said: "Sarah's diapered and in bed, mum. I'm going back to my TV show."
She waited for her mother to reply, who said: "Thanks, honey" before she closed her door and got back onto her couch to watch the rest of the running episode.

Content: It's the weekend, so I'm finally able to access the story forum again and can see your replies and post another chapter. Thanks for the comments so far. Here we go:

Chapter 2

The next day was a Saturday and Lily wanted to sleep in. Ever since she had turned twelve, this meant sleeping until it was at least 11am. Her plans were thwarted by her mother however, who stood in her room at around 7:30am and woke her up.
"Lily," she said, "I've got to run some errands before the fundraiser at Sarah's daycare starts. Her diaper leaked tonight and both her pyjama and her bed are soaked. Can you please take care of that? I really need to go. Aside from that, her diaper didn't leak for weeks, so it's probably your fault anyway since you put it on."
Blinking tiredly at her mother, Lily tried to defend herself: "I was in a hurry. I'm sorry if I didn't do it correctly, but that wasn't my intention."
"I didn't say that you did it intentionally," her mother replied, "I just said that it's probably your fault. And now, get up and help her, please."
"Yes mum," Lily replied before getting out of bed and putting on the clothes she wore the day before.
"Thanks," her mother said before leaving her room and then the house. Once Lily was finished getting dressed, she went over to her little sister's room. As soon as she opened the door, her nose caught the pungent smell of pee in the air. Sarah stood in front of her bed, holding her stuffed rabbit by the ears, looking upset.
"I'm sorry, Sarah," Lily said, "That's probably my fault. I was in a hurry yesterday evening and didn't put the diaper on correctly or something like that."
"It's okay. But it's just not nice waking up in a wet bed. And it stinks," her little sister replied.
"Well, let's get you and your bed cleaned up then, shall we?", Lily said.
Then, she went to Sarah's closet, took out t-shirt, skirt and underpants before taking her little sister by the hand and walking over to the bathroom with her. Sarah waddled with her legs a bit apart and Lily couldn't help but find this cute, even though she pitied her sister. Once they arrived in the bathroom, Lily helped Sarah take off her pyjama. When the pants were pulled down, Sarah's soaked diaper was revealed. The wetness indicator on it had not only turned blue, but disappeared completely in some spots. While Lily put her little sister's pyjama into the washing machine, a thought crossed her mind. What if it actually hadn't been her fault that the diaper leaked? She thought back to the time when she still needed diapers at night and remembered how, sometimes, she would just get up in the morning and keep playing in her diapers, wetting them on purpose when she had to pee. She vividly remembered how she liked both the feeling of the warm diaper as well as the convenience of not needing to stop playing to pee.
This led to her looking at her little sister, who now stood before her in nothing but a soaked diaper, and saying: "Sarah, I have a question. Please be honest with me, I won't scold you and I won't tell mum about it. Do you know how many times you peed in your diaper?"
Sarah turned red, looked down to the ground and stepped from one foot to the other.
"Two or three times," she whispered in reply.
"So, you peed yourself on purpose?", Lily asked, again thinking back to herself about eleven years ago.
"Yes, two times," Sarah replied, "I don't know if I peed while I slept. I peed once yesterday and once when I woke up. But then the diaper leaked."
"Why did you pee yourself on purpose? Why didn't you go to the toilet?", Lily asked, digging deeper.
Realising that Lily wasn't going to scold her, Sarah gained confidence.
She looked at her sister and shrugged, before replying: "I don't know. I like it. The warm diaper feels nice and it's nice not to get up to pee."
Lily nodded, understanding her sister's point from her own experience.
Then, she said: "I'll take the blame for the leaking diaper and won't tell mum. If she finds out you peed your diaper on purpose, she will probably get mad. But you have to be more careful. If your diaper leaks more often, sooner or later, she will find out. Maybe use the toilet in the evening, then you can safely pee your diaper when you wake up."
Sarah hugged her big sister and said: "Thanks Lily. I don't want mummy to shout at me. But I like falling asleep in a warm diaper."
"Well, then don't pee in it when you wake up. Otherwise, it will leak," Lily replied, "And now, let's get you out of that wet diaper and clean you, shall we?"
Sarah nodded and Lily took her diaper off before telling her to get in the shower and helped her get clean. When Sarah got out off the shower, Lily helped her get dressed before she rolled up the diaper and threw it away. Then, both her and Sarah went over to Sarah's room to put clean sheets on her bed.
"Alright," Lily said as they arrived, "I've already helped you take off your wet clothes and I will take the blame for the leaky diaper. I don't want to touch the wet sheets more than necessary, why don't you give me a hand?"
Sarah nodded. Together, they changed the sheet and put a new cover on the duvet. Once they were finished, Sarah put everything in the washing machine with Lily's help before they closed the device and started it.
When they were done, Lily held her hand at her sister's height and said: "Well done, high five."
Her sister high fived her and thanked her for the help.
"Do you want pancakes?", Lily asked Sarah, who replied with a very enthusiastic "Yes".
Lily told her to wait in her room and went to the kitchen to make pancakes for both of them.

Content: Hehe, my mommy forgot to turn on the parental controls again to prevent from accessing the story forum, so here's another chapter early

Chapter 3
Lily made the pancakes and they both sat down at the dining table and ate together. When they were about half finished, their mother came home.
She looked at both of them, smiled and said: "Well, if that isn't cute. My two girls having breakfast together."
They both smiled back at her and Lily said: "I'm sorry, mum. The diaper leak was my fault, the leak guard on one side was a bit crumbled up."
"It's okay, accidents happen," their mother replied.
Then, she proceeded to put the things she bought in the fridge, before telling Lily: "I've got to go in a bit. I told the staff at the daycare that I will help them set everything up. I probably won't be coming back until the fundraising event is over, so can you help Sarah put her costume on and walk over to the daycare with her?"
"Sure," Lily replied, "I wanted to go to the event anyway, so why not."
Her mother thanked her and then started to pack the car with the cake she baked the evening before, a large foldable table and some additional stuff she was asked to bring with her. Meanwhile, the two girls ate the rest of their pancakes.
Once they were finished, Sarah said: "Thanks for the pancakes, Lily."
"You're welcome," Lily responded, "Can you help me clean everything up?"
"Sure," the five-year-old replied, eager to help her sister.
Before they were done doing the dishes, their mother came into the kitchen and said: "Okay girls, I'm off now. Remember Lily, you should be there in two hours. Keep in mind that you have to put Sarah in her costume, too."
Lily nodded while scrubbing the pan she had used.
"Yes mum," she said, "Have a good time and see you there."
"See you there," she replied and left the house.
Once Lily heard the car leaving the driveway, she looked at her little sister and said: "TV?"
Sarah nodded eagerly and the two finished the dishes before they went to the living room to watch TV together.

***
About half an hour before they had to be at the daycare, Lily turned off the TV and said: "Let's get you ready, Sarah."
Her little sister, not to thrilled by the fact that the TV was turned off, nodded unenthusiastically. Lily got up from the couch and signalled Sarah to follow her.
When they arrived in Sarah's room, Lily asked: "So where's your costume?"
Sarah replied: "In my closet" while pointing at the right door of her wardrobe.
Lily opened it and found a coat hanger with black leggings, a black leotard and cat ears on it. She took the hanger out of the wardrobe and closed it again.
"I never realised," she said, "That I didn't ask you what you'll be dressed up as. You're a black cat, aren't you?"
Sarah responded by smiling and meowing at her. Lily smiled and untangled everything that was on the coat hanger. She realised that the costume didn't have a tail and asked Sarah about her.
"It's at the daycare. They will put it on. They will also draw whiskers and a black nose on my face," the little girl responded.
"My, my," Lily said, "You'll look very cute, Sarah."
Sarah responded by meowing again and sitting down on the floor the way a cat would sit.
"Well then, let's get you dressed," Lily said.
Sarah took off her t-shirt and her skirt. Then, she looked at her big sister before looking down at the carpet.
"Is everything alright?", Lily asked a bit worried.
Sarah stepped from one foot to the other and kept looking at the floor.
Then, quietly, she asked: "Can you help me put a diaper on?"
"What?", Lily said, more from disbelief than from not understanding her little sister's question.
"Can you help me put a diaper on, Lily?", Sarah repeated, this time a bit louder.
"But why?", Lily asked.
"I can't go to the toilet on my own in this costume," Sarah responded, "Mum Is busy selling cake and there are only two teachers there today, and I don't like them. They're always so rough when they help me with anything."
"But I'm there, Sarah. I can help you go to the toilet", Lily objected.
Sarah thought for a moment, before she said: "Yes, you are there. But what if I notice to late that I have to pee? It takes time to take the costume off. I don't want to pee myself in front of everyone."
Lily smiled at the little girl's creativity and decided to ask her another question.
"Sarah," she said, "Is it possible that you just want to wear a diaper because you like it? And that you think this is a good opportunity because mum will be too busy to notice it?"
Her little sister turned bright red before nodding shily.
"Well then," Lily said, smiling at Sarah, "Let's get you diapered up, hmm?"
Sarah's face lit up with a big smile and she hugged Lily and thanked her. Lily lifted her onto the changing table and grabbed a fresh diaper.
"Lie down for me please. And you'll have to get rid of your underwear," she said.
Sarah pulled down her underpants and kicked them away. Then, she got down on her back and Lily slid the diaper underneath her, adjusted everything until the fit was right and carefully taped it shut.
"All done, little kitty," she said, "Hop down."
Sarah meowed and hopped from the changing table. While Lily looked at the costume and tried to figure out how to put it on, she realised what the problem was. First, the leggings would have to be put on. The leotard, which had a Velcro strip to attach the tail to, would be worn over the leggings. Thus, the leotard would have to be taken off completely before the leggings could be pulled down if the wearer had to go to the toilet. Once Lily realised how to put the costume on, she helped her sister to dress up. First, she helped her to put the leggings on before helping her with the leotard.
When she was done, she said: "Okay Sarah, please turn around."
Her little sister turned on the spot and Sarah checked if the diaper was visible from any angle.
Then she said: "Okay, I don't think anyone will see your diaper, the leotard covers it quite well."
"Thank you, Lily", Sarah said and hugged her again.
Lily put the cat ears onto her sister's head and bent down to kiss her on the forehead.
"Okay," she said, "I think we should get going."
She took her little sister by the hand and they left the house together.

Content: Here we go, I didn't manage to proofread it in depth, but my whole weekend is pretty much planned out, so I'll still post the next chapter anyway. There at least shouldn't be any obvious mistakes from what I crossread:

Chapter 4
When they arrived, the whole event was in full swing. Someone put up a couple of donation boxes, next to pictures of the daycare's partner village in Africa. At the end of the driveway, someone had built a small stage on which the youngest children from the daycare danced around mostly uncoordinated, dressed up as rabbits.
Before Lily could even orientate herself, one of the teachers already saw her and her sister and said: "Oh, you're right on time. We were already looking for Sarah."
Without saying anything else, the woman took Sarah's other hand and pulled on it quite rough. Lily let go of her sister, who didn't seem too pleased with the treatment she received. Lily pretty much instantly understood why Sarah wouldn't want someone like this woman to help her go to the toilet.
"Maybe you could be a little gentler with my sister," Lily told the woman.
She however either didn't listen or didn't care, as she kept pulling Sarah with her. Lily could hear her asking Sarah if she needed to go to the toilet, which Sarah denied by saying that she just went at home before coming her. Then, they were out of Lily's hearing range.

***
After her sister went with the teacher, Lily had decided to look for her mother. She found her inside the building, sitting behind the folding table she had brought with her, selling cake together with two other women. A sign on the table informed possible customers that the whole profit would go to the daycare's partner village.
"Hey mum", Lily said when she approached the table.
"Oh, you've made it, great, " her mother responded, "Where's Sarah?"
"She got yanked away from me by one of the daycare teachers," Lily replied.
Her mother's expressions darkened and she nodded: "I know exactly who. I don't like her, if I'm honest. She seems to be annoyed by every single child around here. Quite strange, considering she picked being a daycare teacher as her profession."
Lily nodded in response. Before she could say anything else, her mother changed topics.
"Listen, Lily," she said, "I know, I've already asked you to do a lot this weekend, but can you help me out again?"
"Sure," Lily sighed, "What is it?"
"I agreed to meet up with my friends later today. We wanted to go for dinner and to the cinema afterwards. I totally forgot that it was today. Are you free tonight? Can you take care of Sarah, get her something to eat, tuck her in bed and so on", her mother asked.
"Sure," Lily nodded, "I don't have any plans for the rest of the day, so why not. But it's gonna cost you."
"What do you want?", her mother asked.
"Not much," Lily replied, "I wanted to go shopping with Lisa next Saturday. Her mother will take us there, but we need someone to pick us up when we're done."
"Okay, I'll do that, no problem," her mother responded, "Thanks for taking care of Sarah."
"You're welcome," Lily responded.

***After talking to her mother a bit more, Lily decided to look around and explore the daycare a bit more before it was time for the performance of her sister's age group. She wandered around for a bit, talked to a couple of people, some of which she knew because they were parents of her sister's friends. Then, when it was finally time for her sister's performance, she sat down on one of the folding chairs in front of the small stage, next to her mother who was already eagerly waiting.
"She's gonna be so cute," her mother said.
"I know," Lily responded smiling, "I dressed her up."
It didn't take long until the woman who took Sarah with her when they had arrived took the stage. She had a microphone in her hand and switched it on. The small speakers in front of the stage made a popping sound and then the screeching sound of a feedback could be heard once the woman started to talk. She turned the microphone back off and resorted to shouting to the people who sat in front of the stage rather than giving it another try.
"Thank you for coming," she said, "My name is Anna and you will now see our five-year-olds perform their kitten dance."
She left the stage and about twelve to fifteen children, all in the same costumes as Sarah's but in different colours, entered the stage. A cheesy song about little cats and their mothers started playing and the kids started dancing to it. It was a bit more coordinated than what Lily had seen with the younger kids, but there still was a lot of chaos.
"You can't deny they're cute," Lily said to her mother, "But they certainly lack in coordination skills and rhythm."
Her mother giggled poked her elbow into Lily's side.
"Oh, come on," she said, still giggling, "They're little children, give them a break."
They continued to watch the whole performance. Once it was over, the children all bowed down while the audience applauded. Anna returned to the stage, this time not even bothering to try using the microphone.
"Thank you for your applause," she shouted, "Please consider donating for our partner village so they can start building a school. As we all know, education is the path to everything. If you want to pick your child up, you can do so in about ten minutes in front of the blue group's entrance."
As she left the stage again, Lily's mother looked at her and said: "Can you please pick up Sarah? You know where the blue group is, do you?"
Lily shook her head and her mother went on: "Follow the hallway where I stand and sell cake, then at the end, turn left. There's a huge blue dot over the entrance."
"Okay," Lily said, "I'll pick her up. If she wants to go home, can I go with her? Or should we stay here?"
"No, feel free to go home. I don't know when I'll be there, I'll text you as soon as I know," her mother responded.
Lily nodded and they both got up. While her mother went inside to go back to selling cake, Lily realised that she had to pee and thus, went to look for the restrooms.

***A couple of minutes later, Lily left the restroom after washing her hands. Looking at her watch, she realised that it was about time to pick Sarah up, so she went over to where her mother told her to go. As she passed the cake stand, she waved to her mother, who didn't notice it as she was too busy handing a piece of cake over to someone while talking to them. When she arrived at the door with the blue dot over it, she went inside, just to be stopped by Anna.
"Who are you? What are you doing here?", the woman asked in a very unpleasant way.
"I'm here to pick up my little sister," Lily replied.
"And who would that be?", Anna said, not getting any friendlier.
"Sarah. I dropped her off about an hour ago or so. Or rather you yanked her away from me. Don't you remember?"
The expression on the woman's face darkened and she said: "Oh, you. The one with the cheeky remark. Wait outside, I'll get your sister."
Before Lily could respond, Anna hand pushed her out of the room and shut the door in front of her face. Lily decided to wait instead of opening the door again and saying anything to Anna. Fortunately, she didn't have to wait long until Anna opened the door again, with Sarah on her hand. Sarah broke away from Anna's hand and ran over to her sister to hide behind her.
"Oh, come on, don't act like I did anything to you," Anna said while watching Sarah hide. Then, directed at Lily, she continued: "Why is Sarah wearing a diaper? She's way too old to do so!"
"And why," Lily asked, feeling anger rising within herself, "Do you know that? And why exactly do you even care? Is she your daughter, or you sister? No, she isn't."
"I went to the toilet with her," Anna replied.
"Didn't she tell you that she went before we left home?", Lily asked in response.
Anna remained silent for a moment before saying: "Whatever. The kids say thing like this all the time, and then they end up wetting themselves, so I took her to the toilet. She resisted and once I managed to get her out of her costume, I realised why."
Lily, by now having turned bright red, said: "You did what? Get lost, now, before you find yourself with my fingernails in your face. And do not dare to get near to my sister ever again. There will be consequences for this."
Lily grabbed Sarah's hand, who still hid behind her, and stormed off. Once she arrived at the table her mother stood behind, she took her aside and filled her in on the situation. She didn't mention the diaper, as she would rather explain her reasoning for putting Sarah in one later or the next day at home. When she was finished, Lily saw her own anger mirrored in her mother's face.
"I'll talk to her, and to the management of the daycare. Being unfriendly is one thing, but this is intrusive behaviour. She can't do something like this. My shift is over in half an hour, once that's done, I'll talk to her," their mother said.
Then, after a brief pause, she continued: "Can you take Sarah home, please? Comfort her a bit?"
Lily nodded. Both girls hugged their mother and Lily left the building, with Sarah on her hand, making their way home. Once they were a couple of crossroads away from the daycare, Sarah's mood started to cheer up. Instead of just trotting along on her sister's hand, she started to skip. Then, while they had to wait at a pedestrian crossing for the stoplight to turn green, she signalled her sister to bend down to her.
When Lily was close to Sarah's head, she whispered in her ear: "Do want to know a secret?"
Lily nodded and Sarah started to giggle.
"When we left the stage, I peed in my diaper," Sarah whispered, still giggling.
Lily patted her little sister's head as the light turned green and they went onwards.

Content: Again, I couldn't find the time to proofread the chapter completely, but I at least managed to persuade my girlfriend to allow me to access the story forum to post it:

Chapter 5
When Lily unlocked the door, Sarah ran inside, not even bothering to take her shoes off. Lily, who was a bit more relaxed about returning home than her little sister, went inside, shut the door and took off her shoes.
Then she said: "Come over here little kitty, we have to take your shoes off."
Sarah returned, almost sliding around the corner of the hallway, and hugged her sister's legs before taking her shoes off, refusing any help from Lily. When she was done, she put them next to Lily's shoes and wanted to run off again, but Lily told her to wait.
"Do you want to keep wearing you cat costume?", she asked her little Sister.
Sarah stood around for a moment and made her thinking face.
Then, she replied: "Can I keep my diaper on if I take the costume off?",
Lily shrugged and said: "Sure, you said you wet it anyway, didn't you? Then why bother taking it off? Just make sure to tell me when you've used it again so we can take it off before it leaks, okay?"
Sarah nodded and then asked Lily to help her take off the costume. They went to Sarah's room, where Lily followed essentially the same process as she did when helping her little sister put on the costume a couple of hours earlier, just in reverse order. Once cat ears, the leotard and the leggings had come off, Sarah stood in front of her older sister in nothing but her wet diaper. As Lily saw the partially blue wetness indicator on the diaper and noticed the faint smell of pee that was coming from her sister, a wave of nostalgia hit her.
"Are you okay, Lily?", Sarah, who seemed to have noticed Lily's sudden rush.
"Yeah, sure," Lily replied, "I was just lost in my thoughts for a moment. Let's get you dressed up again, shall we? You can't run around in nothing but your diaper the whole day."
She then helped Sarah to put on the clothes she had worn in the morning.
When her little sister was completely dressed again, Lily asked: "Wanna play Snap?"
Sarah nodded enthusiastically before storming off to the living room while yelling: "I'll get the card deck."
Lily smiled over Sarah's childish enthusiasm for something as mundane as a card game and then thought about the feeling that had hit her when she saw her little sister in nothing but her wet diaper. What was that supposed to mean? ***
The girls played a couple of games of Snap before Lily took Sarah with her to her room. Sitting on Lily's couch, the two girls played Mario Kart on Lily's switch together until their mother came home.
"I'm home," she said as she opened the door.
Lily got up from the couch and said to her sister: "Stay here for a minute, okay? And don't tell mum about your diaper. I will talk to her about what Anna said to me and you can tell her afterwards, okay? Just don't tell her that you're wearing a diaper right now."
Sarah agreed, and so Lily left the room to go to the living room.
"So how did the talk with Anna go?", Lily asked.
Her mother shook her head and raised her eyebrows, visibly annoyed, before saying: "I didn't talk to her. Turns out, before my shift selling cake was over, Anna excused herself and went home because she had a bad headache."
"Mhhm, she sure did," said Lily sarcastically.
"I at least talked to the manager about it," Lily's mother continued, "Once Anna feels better again, there will be a talk between me, her and the manager to clear things up."
Lily nodded and said: "Seems better than nothing. Do you want me to tell you everything in detail? And I also think that Sarah can tell you everything from her perspective as well."
Her mother nodded and said: "Please help me get the table out of the car, then we can sit down and you can tell me everything that happened."
Lily nodded and the two went outside to unload the car. Once they were done and had put everything back where it belonged, Lily went to her room to get Sarah and the three of them sat down in the living room.
Lily began to talk: "I think I have to confess something to you first, or at least tell you. From my point of view, it isn't that big of a deal, but I'm not sure how you will react."
Her mother raised her eyebrows and said: "Alright, continue."
"When I helped Sarah putting her costume on in the morning," Lily said, "She asked me if I could put a diaper on her. After talking it through with her, she said that she would feel better if she wore a diaper, as she couldn't take off her costume without help and didn't want Anna to help her. I decided that this probably won't be that big of a problem, so I diapered her."
Her mother nodded and said: "I mean, I won't be cheering about this, but given what you said, I can't blame you. It's a reasonable decision."
"Okay," Lily said feeling relieved.
She then continued to tell her mother the whole story, starting with how roughly Anna took Sarah away when they arrived and ending with the argument she had with Anna when picking Sarah up. While listening to the detailed account of what happened, the girl's mother's face turned more and more red.
When Lily was finished, she said: "Anna did what? Even though Sarah told her that she went to the toilet at home and didn't need to go, she undressed her to take her to the toilet? And then, she scolded you when you picked Sarah up because she was wearing a diaper? What the heck is wrong with that woman?"
The situation didn't get much better as Sarah now spoke: "She tried to take my diaper off. I told her that I went to the potty at home and that I wear the diaper in case I pee myself because I'm nervous. She still tried to take the diaper off, until Hannah came to the toilet and asked her why Anna was in there with me in a dry diaper. Anna said nothing and just left the room. Hannah then helped me to put the costume back on."
Their mother shook her head in disbelief: "Good lord," she said, "What is wrong with her? Something has to be done. Someone like that can't keep taking care of children. And even if they don't kick her out, I won't allow her to get in contact with you ever again, Sarah."
"Thanks mummy," the little girl replied.
"Is that it?", their mother asked?
Sarah nodded and said: "Yes. Hannah helped me put the costume back on and put the tail on and then we went outside. When we were done, Hannah took the tail off again and I played with the other kids. Then Lily came and argued with Anna and then took me home."
Their mother nodded, thinking about what her daughters just told her.
Then, out of curiosity, she asked Sarah: "What about the diaper? Did you keep it dry? And did you take it off when you came home?"
Sarah looked at the ground and remained silent.
Lily looked at her, sighed and said: "It's okay, Sarah. You can tell mum."
Sarah nodded shily and then lifted up her skirt, revealing the wet diaper underneath. Their mother shook her head, but she smiled while doing so.
"Well then," she said, "I think that the experiment is over now, isn't it? Lily, please take her to her room, take the diaper off and help her to put her underpants back on, will you? I don't want Sarah to unlearn how to use the toilet."
Lily nodded and got up from the couch. Sarah, looking a bit sad because her diaper-wearing-time was cut short, followed her. Their mother kept sitting on the couch, contemplating what to do because of Anna's behaviour. ***
Lily pitied her little sister who still had the sad look on her face when the pair arrived at her room. Lily closed the door behind them and a thought crossed her mind.
She smiled at the five-year-old and said: "You don't have to be sad because you have to take your diaper off. I've got an idea."
Sarah's face brightened with a smile and she said: "What's the idea?"
"Well," Lily responded, "First of all, do you need to pee? If so, why don't you use your diaper? Then you can at least get another pee out of it."
The little girl smiled and nodded. She made a concentrated face and turned a bit red as Lily looked at her.
Lily decided not to comment on this and continued: "Also, mum's away for the whole evening. She goes out for dinner with a couple of friends and afterwards they go to the cinema. So why don't we wait until mum left and then I can put you in a diaper? Only if you want to, of course. If it's still dry enough when it's time for you to go to bed, you can keep it on and if it's too wet, I'll change you. How does that sound?"
Sarah nodded eagerly.
"Alright then. But you can't tell mum anything about it, okay? If she finds out, we'll both be in trouble," Lily added.
Her little sister nodded again and said: "I don't want to get in trouble with mummy. I won't tell her about it."
"Great," Lily said, "Then let's get you out of your wet diaper, shall we? Please take your skirt off."
Sarah did as she was told and Lily lifted her onto the changing table. Lily asked her to lay down on her back and as her little sister obeyed, Lily realised that the wetness indicator was now blue all the way and the diaper had swollen quite a lot. Now that she got closer, she also noticed a quite strong smell of pee.
"It seems like someone really had to go, huh?", she asked her little sister.
Sarah nodded and turned red again, saying: "Yes. I already had to pee when we were playing Mario Kart."
"Why didn't you go then?", Lily asked while undoing the tapes of the diaper and removing it.
"I don't know, I wanted to wait," Sarah replied.
Lily nodded and rolled up the wet diaper before taping it shut and throwing it into the trashcan next to the changing table. She then took a wet wipe from a small pack that was kept on the changing table and carefully cleaned her little sister.
When she was done, she said: "That's it, Sarah. Come on, jump down, put your underpants and the skirt on."
The little girl nodded and jumped down from the changing table before putting her clothes back on. While Lily looked at the changing table, the strange nostalgic feeling hit her again. Should she try it? Should she just take one off Sarah's diapers and try to put it on when their mother was away? Somehow, she really wanted to try it, but simultaneously felt weird about having thoughts like this. She looked at Sarah, who was already busy playing with her stuffed animals once she had finished getting dressed and made a decision. She threw the wipe she used to clean Sarah into the trashcan and then, while carefully looking at her sister, took a diaper out of the basket they were kept in. Feeling her heart race, she hid it under her t-shirt and left the room.
"Play alone for a bit, or with mummy, okay, Sarah?", she asked her little sister as she exited the room.
Sarah mad a hum of approval and Lily closed the door behind her while still holding onto the diaper under her shirt with one hand so that it won't fall down. Then, she raced to her room before their mother could notice anything, and closed the door. Frantically, she looked around for a place to hide the diaper until their mother went out with her friends and decided to just put it under her mattress. She lifted it up, stuffed the diaper underneath it and put it back in place. Then, she sat down on her couch, her heart still racing, trying to calm down.

Content: This one's a longer one, but due to my workload both this week and weekend, I don't have time to proofread it thoroughly. I skimmed through it, but there might still be some mistakes. Hope you enjoy it anyway.

Chapter 6
"Alright girls, I'm off now. Lily, take care of your little sister, and Sarah, be nice to your big sister. Don't expect me back before midnight. And Lily, remember that Sarah should be in bed by 9pm at latest," their mother said.
Lily nodded.
"Okay, bye then girls. Love you," their mother continued.
"Bye mum, love you too," the girls replied in unison.
Then, their mother left and closed the door behind her. They could hear how she started the car and reversed down the driveway.
"Okay," Lily said, "Let's wait for a couple minutes so we can be sure that she doesn't come back because she forgot something. Then, I can diaper you if you still want me to."
Sarah nodded enthusiastically and Lily said: "Alright. I'll go to my room for a couple of minutes. You can stay here or go to your room and play. I'll come over as soon as I think we're safe."
Sarah nodded again and while Lily went off to her room, her little sister did the same. As Lily now entered her room, her heart raced as she thought about what was going to do. She hadn't worn a diaper for ten years by this point and even though she had always liked the feeling of a warm, wet diaper, she never thought about wearing one after she became dry at night. At least not until she saw her little sister in her earlier that day. Lily couldn't really pin down why the idea hit her at that exact moment. She had seen Sarah wearing a diaper before, both a dry and a wet one, and had diaper her hundreds of times before bedtime and had also changed her when she was younger. Maybe it was the fact that Sarah had admitted to peeing in her diaper voluntarily that reminded Lily of herself at that age that had triggered those feelings.
As Lily now closed the door behind herself, nothing of that mattered anymore. She took off both her pants and her panties and lifted the mattress up to retrieve the diaper from underneath it. As she now lied down on her bed and folded the diaper open, she saw it in a different light. She had probably put hundreds of those diapers on her little sister, but this time, it felt different.
Lily raised her but and slid the diaper underneath it like she would always do when diapering her little sister. As she pulled the front of the diaper up between her legs, the soft fabric on the inside touched her private parts. It was an oddly pleasant feeling, but Lily was too nervous to enjoy it. She carefully grabbed one of the tapes from the back of the diaper to start taping it shut. Now was the moment of truth. Would the diaper fit her? Or would she be too big?
To Lily's delight, she managed to apply both tapes without one of them ripping. For probably the first time in her life, she was thankful for being smaller than every other girl her age she knew. Now that the diaper was taped on, Lily got up and looked at herself in the mirror on the door of her wardrobe from all angles. While it was noticeable that Pampers hadn't intended for someone of her age and size to wear this diaper, it still fit quite well. The tapes held everything in place and didn't feel too tight around her body.
Carefully, Lily pulled out the leak guards on both sides of the diaper. While she wasn't sure if she was actually going to use the diaper for its intended purpose, she thought it was better to be safe than sorry. Once she was done making sure that the leak guards were properly placed, she pulled her pants back on, leaving the panties lying on the floor. Then, she left her room and went over to her little sister.
As she entered Sarah's room, the little girl sat on her small desk with a colouring book and a couple of pencils. When she got closer, Lily noticed Sarah's skirt and her underpants lying on the floor.
Lily giggled and asked: "Why are you naked?"
"I'm not naked," her little sister responded, "I'm wearing a t-shirt."
Then, while Lily was still giggling, Sarah added: "I wanted to make it easier for you to diaper me."
"Aww, that's so sweet of you," Lily smiled, "Well then, let's get you on the changing table and put you in a diaper, shall we?"
Sarah nodded enthusiastically and got up from her chair. Lily lifted her onto the changing table and Sarah laid down on her back without being asked to do so. As Lily took a fresh diaper out of the basket and unfolded it to put on her sister, she suddenly became very aware of the diaper between her own legs. While she taped Sarah's diaper shut, she contemplated with herself if she should tell her little sister that she was wearing diapers too.
Once she had finished diapering Sarah, she said: "All done, you can get down now."
The little girl jumped from her changing table and looked at her sister.
Then, she looked down on the ground and shily whispered: "Lily, can I wear just my diaper and a t-shirt like I did when I was little?"
Lily giggle again, pulled out of her thoughts by this question, and answered: "You're still little, Sarah. But sure, why not? I don't see any problem with it, it's quite warm."
Sarah put her hands on her hips and made an exaggeratedly indignant face.
"I'm not little", she protested, "I'm five already and I'm turning six this year."
Lily laughed and said: "I would almost believe you, if you weren't standing in front of me in nothing but a diaper and a t-shirt."
That led to both of them laughing and Lily decided that she could reveal to her little sister that she was wearing a diaper, too.
"Do you want to know a secret, Sarah?", Lily asked.
Sarah nodded and looked at her sister with undisguised curiosity. Lily pulled down her pants and revealed the diaper underneath. Sarah opened her mouth in astonishment once she realised what her big sister was wearing.
"Is that one of my diapers? Why are you wearing it?", she asked.
Lily shrugged and answered: "Yes, it's one of yours. And I don't know. I was just curious about it, I think. When you told me that you liked the feeling of wearing a wet diaper, I was reminded of when I still needed diapers at night. I also liked how it felt when the diaper was wet, so I thought why not try one of yours on."
Sarah, still looking at her big sister's diaper, had lost her initial shyness and said: "I got an idea Lily! Why don't we both wear nothing but diapers and a t-shirt?"
Lily shrugged again before taking her pants of and saying: "Sure, equal rights for everyone, I guess."
"What does that mean?", Sarah asked
"In this case that it's just fair for us both to wear nothing over our diapers," Lily responded.
Her little sister nodded Lily suggested: "Why don't you let me bring my pants to my room and then we have dinner together. After that, we'll watch a movie together. You can choose which one."
"Yes please! Totoro please!", Sarah exclaimed.
"Alright," Lily said, "I'll put my pants away. Why don't you go to the kitchen already?"
Sarah nodded and ran off. Lily couldn't help but feel a little proud of her little sister for rather watching My Neighbour Totoro than any Disney movie like most kids her age would do. Then, she brought her pants over to her room. It felt kind of strange to walk around in nothing but a diaper, but Lily reminded herself that their mother won't come home until late in the evening so no one but her sister would see her this way.
Once her pants were put away, Lily went over to the kitchen where Sarah already sat at the table and waited for her sister.
"So, what do you want?", Lily asked, "Cereal for dinner?"
Their mother only allowed Sarah to eat cereal in the morning, so the little girl was thrilled by her sister's proposition. Lily took the cereal box out of the cupboard and prepared two bowls, one for herself, and one for her siter.
Once they were done eating, Lily said: "I'll clean up. You can go to the living room and get cozy already."
Sarah nodded and got off her chair before running over to the living room. Lily washed the dishes and put everything back where it belonged before she follower her sister. Once in the living room, she got onto the couch next to her.
"Come on Lily, let's cuddle," the little girl said.
Lily switched on the TV and started the movie before she moved closer to her sister, who instantly snuggled against her.

***
When the movie was over, it was already past Sarah's bedtime.
Lily turned off the TV and said: "Well Sarah, I think it's time to tuck you in, isn't it?"
Sarah shook her head and replied: "No, I'm not tired at all", right before letting out a huge yawn.
That made both girls laugh and Sarah admitted: "Maybe I'm a little tired."
Sarah stood up on the couch and stretched herself. Lily wanted reprimand her, as their mother never allowed her to stand on the couch, but was distracted by the blue line on Sarah's diaper.
"Did you wet yourself while we were watching the movie?", Lily asked her sister with a bit of surprise.
Sarah nodded and said: "When the cat bus came on. I already needed to pee and I'm a little afraid of the cat bus. It looks so strange. So, when it came on, I was frightened and peed myself."
Lily nodded remembering that when she was that age, she was disproportionately afraid of the turtles in Finding Nemo. Almost automatically, Lily put her index finger in the leg cuff of her sister's diaper. She squished the core to determine how wet it actually was.
Then, she said: "Well, I think it's still dry enough to last through the night. Do you want me to change your diaper, or do you want to keep wearing this one?"
Sarah didn't even think before responding: "This one, this one, this one! It's nice and warm!"
Lily smiled and told her little sister to get down from the couch and onto the floor before she hurt herself. Then, she sent her off to the bathroom to brush her teeth. A couple of minutes later, Sarah emerged from the bathroom, letting out a huge yawn once again. Lily checked that she had actually brushed her teeth before accompanying her to her room. Once she got down on her bed, Lily tucked her in and kissed her on the forehead.
"Good night, Sarah," she said, "And remember, don't pee in your diaper when you wake up tomorrow, otherwise it will leak."
The tired five-year-old nodded and looked at her sister's diaper.
"Are you still dry?", she asked.
Lily nodded and pointed at her diaper before saying: "Yep. Look, the line's still all yellow."
"You're really a big girl and I'm really still little, huh?", Sarah yawned.
"Maybe," Lily said, "Or maybe you're also a big girl that likes to wear a wet diaper from time to time. Who know. Good night, Sarah."
"Good night, Lily", the girl responded as Lily left her room and turned the light off.
Lily went back to the living room and grabbed her phone. At about three quarters of the movie, she had felt the urge to pee. After contemplating for moment, she had decided to wait until she had put her sister to bed. Then, she wanted to try to wet her diaper. As she now went to the bathroom, her phone in one hand, she felt her heartrate speeding up again. She turned on the light and opened the door before entering the bathroom. Once she was inside, she closed the door and locked it, just in case. She had decided beforehand that she would try wetting herself while she stood in the shower, as this way, the clean up would be easy if the diaper would leak.
However, as she now found out, just thinking about it and actually doing it were two completely different things. She got into the shower and stood there with her legs quite far apart. But even though she felt like she was close to bursting, she just couldn't let go. Something was preventing her from doing so. She concentrated on it and tried to force the pee out, but except for a couple of droplets, nothing happened. Annoyed, she thought about giving up before the phone in her hand gave her an idea.
She opened an incognito tab in the browser and searched "How to pee a diaper on purpose." The results varied wildly, but most websites she visited were agreed on two points: For one, it was difficult for a potty-trained person to wet themselves on purpose without any practice and, for two, the best way would probably be to sit on the toilet while trying this, to trick your body into believing that you'd actually pee in the toilet rather than in the diaper.
Lily got out of the shower, opened the toilet lid and sit down like she normally would when she had to pee. She concentrated fully on her bladder and told her body that it was fine to let go, as she was sitting one the toilet. When it finally worked, she was so surprised that she almost stopped peeing reflexively. With a bit more concentration however, she managed to keep going, feeling the warm stream flooding into her diaper. Once she was finished, she felt a huge sense of relieve as her bladder had been so full that it started hurting. She inspected her diaper and expected that it had leaked. However, when she got up from the toilet, she couldn't find any traces of pee inside the bowl. Looking around her legs, there was no wetness either. The core of the diaper however had swollen to almost double the size it had been when it was still dry. The yellow wetness indicator which she had shown to her little sisters just a couple of minutes ago had now turned to a dark shade of blue over the whole length of the diaper.
Curiously, Lily pushed against the diaper between her legs. She could feel a little pee coming out, but the diaper had already absorbed most of it. Shivers ran down her back and she could feel a tingle in her most sensitive region when the squishy fleece of the diaper pushed against it. Then, she took her hand off the diaper and decided to explore the new feeling of wearing a warm, wet diaper a little more. She turned off the lights, left the bathroom and got back to the living room. Before she sat down on the couch, she carefully checked her diaper for any leaks and squished against it again. This time, no wetness came out of the core and the inside of the diaper still felt dry, so she determined that it was safe to sit down.
Once she sat on the couch, she felt a rush going through her whole body. The wet diaper pressing against her body brought her back to a safer, easier time in her life. It reminded her of when she was a little child and there were almost no worries in her life. Subconsciously, she kneaded the front of the diaper with her right hand, like she did when she was the age her sister was now. It felt nice, playing with the wet, squishy material of the diaper. When she realized what she did, she decided to stop. She lied down on the couch, turned the TV on again and opened Netflix to watch How I Met Your Mother for probably the hundredth time. While she was laying there, she realized how tired she was and slowly dozed off.

Content: Just a heads-up, as I've got a very busy work schedule for the next to weeks, including working away from home for three days, I'll probably post the next chapter either today or tomorrow because I'm not sure that I can post it next weekend.

Content: Good lord, what a couple of weeks that were. Sorry for not updating, but I've been working basically non stop since the 25th of August, usually 12-14 hours a day to get an important project done. Had to get i finished, tested and implemented on site for the customer. It went as far as my girlfriend deciding to put me in Rearz Daydreamers for most of the time as this would cut daily diaper changes down to a maximum of two.
Now however I'm done, the project was a success and I've got the rest of the week off, so here's the next two chapters.

Chapter 7
Lily was woken up by the sound of keys in the front door. She blinked and needed a moment to orient herself. She looked at the TV on the adjacent wall showing Netflix's "Are you still watching?" screen and was wide awake. Her mother had returned and she was lying on the couch in nothing but a t-shirt and a diaper, a wet one at that. She panicked and quickly grabbed one of the blankets from the back of the couch to cover herself with it. Just in time, as it turned out. The moment Lily put the blanket over her body, her mother entered the living room.
"Oh, hello," she said, a little surprised, "I didn't expect you to still be here."
Lily yawned and replied: "I dozed off while watching Netflix. I'll go to my room; I just need to wake up a bit more."
Her mother nodded and went back to the hall to take off her shoes and hang her purse away. Lily's thoughts raced. How would she get to her room without her mother noticing her diaper? An idea formed in her head: She would just wait for her mother to go to the bathroom like she usually did when she came home, and then sneak into her room to put her pants back on. That way, she would be safe from her mother discovering her diaper without needing to take it off.
While these thoughts went through Lily's head, her mother came back from the hall and sat down next to her on the couch.
"How was your evening?", she asked.
"Well," Lily said, trying to hide her nervousness, "We had dinner and then we watched Totoro for like the twentieth time before I tucked Sarah in. Then I put on How I Met Your Mother and fell asleep while watching it."
"Classic," her mother smiled, "Well then, do you want to go to bed?"
Lily nodded and said: "Yes, just give me a minute. I need to fully wake up."
"Well, let me help you with that," her mother said, "You can't wake up while you're all snuggled up like that."
Before Lily could protest, her mother pulled the blanket away. While Lily turned bright red, the look on her mother's face switched from surprise to disbelief to something Lily couldn't quite grasp.
"Why," her mother stated, "Are you wearing one of Sarah's diapers? And why is it wet?"
"I…. I….. I…..," Lily stuttered.
Then, she started to cry.
"Hey, Hey," her mother said and gently stroked Lily's arm, "There's no need to cry. Relax, honey. I just asked you something. Calm down and when you're ready, please answer."
Lily nodded while sobbing. She tried to calm herself down, breathed slow and deep and did her best to stop crying. Her mother didn't seem angry, so maybe there would be no punishment for what she had done.
"You have to promise me," Lily said, still sobbing, "Not to drag Sarah into this. She told me a secret and I promised not to tell anyone."
Her mother nodded and replied: "I promise."
Lily continued: "When I helped Sarah change her bed sheets, she told me that she peed her diaper on purpose, once in the evening and once when she woke up. Together with the amount she probably peed while she was sleeping, that was too much for the diaper. That's the actual reason why it leaked, not because I had put it on wrong. I asked her why she did so and she confessed to me that she liked the warm, squishy feeling of the wet diaper."
Her mother looked at her attentively, but didn't say anything, so Lily went on.
"When she told me that, I remembered that I used to do that, too. Until you caught me and gave me the worst scolding I received in my whole life, that is. Thus, I told Sarah that she should keep quiet about it and that I would take the blame for the leaky diaper. I also told her to only pee once instead of twice while she was awake so there would be no further leaks."
Her mother nodded and asked: "And did the diaper Sarah wore at the daycare today have anything to do with this?"
Lily shook her head. She decided to maintain this small lie.
"No," she replied, "Sarah actually asked me to put a diaper on her because she was afraid of needing Anna's help to go to the toilet."
Her mother nodded again. Then, both of them remained silent for a while.
"Well," Lily's mother finally said, "I'm gonna be honest with you. I'm not completely sure how to deal with this yet. I'm sorry for scolding you back then, it's something I thought about over and over again for the last couple of years. I was at my lowest point and I shouldn't have shouted at you like that. But maybe you can understand me. I was pregnant, we had no money and you father refused to pay any child support. When I found out that you didn't need the diapers anymore but rather used them on purpose, I snapped because they were expensive and sometimes, the decision for me was either have dinner or buy a pack of diapers."
"I'm so sorry," Lily interrupted, "I didn't know that."
"Of course you didn't," her mother said, "You were five years old and I did my best to keep you away from all those problems. However, to get back on topic: I'm not sure what I think of the fact that you're wearing a wet diaper right now. I probably have to sleep on it for a night or two. But you don't have to be afraid of getting into trouble for that. I understand your reasoning behind it and it doesn't seem like you're hurting anyone with it, except maybe your sister because she's going to run out of diapers."
Both Lily and her mother laughed at that.
Then, she continued: "I also won't punish Sarah for what you told me. As long as her diapers don't keep leaking, I won't even bring it up that I know she wets on purpose. I think everything else would lead to trust issues between you and her. I think it's for the best If we both went to sleep now. Let's talk about it tomorrow, okay?"
Lily nodded. She got up from the couch and pulled her mother into a tight hug. By now, she had stopped crying and enjoyed her mother gently stroking her back. When they eventually let go, Lily thanked her mother for not scolding her or her little sister.
"Of course, sweetheart, " she replied, "Back then, I mainly was angry because we had no money. Now, let's get into bed and sleep."
Lily nodded and went on the way to her room.
Once she walked around the couch, her mother looked at her and said: "Well, I have to admit that there's no denying that you look stinkin' cute in a diaper."
Lily blushed but smiled when she heard this.
"Thanks," she said, "Good night, mum."
"Goodnight, Lily," her mother answered, "See you tomorrow."
"Goodnight mum," Lily responded and went to her room. Without any further ado, she got down on her bed, slipped underneath the blanket and closed her eyes. Her right hand kneaded her diaper again until she fell asleep. Chapter 8
The next morning, Lily woke up because the sun shone in her face. She blinked and wondered why she hadn't closed the blinds until she remembered what happened the night before. Her hands instantly went between her legs to find the squishy wet diaper that by now had cooled down by quite a lot. She still liked the feeling however. Then, she stretched and got out of bed. Much to her surprise, the tapes of the diaper, which was made for children that were maybe six or seven years old, still held up and showed no signs of ripping or loosening.
Turning around in front of her mirror, she realized why. While they were stretched out quite well, they weren't at their limit. Lily sighed, once again reminded by the fact that she was still waiting for the growth spurt all her friends had already made. Instead of the self-pity she would normally feel though, this time she smiled at the thought that her rather small size allowed her to fit into her little sister's diapers.
For a moment, she thought about taking the diaper off, but then decided to keep it on for a bit longer. At least until after breakfast, after which she would have to take them off anyway to take a shower. She grabbed her sweatpants from the floor, put them on and then took the t-shirt she had worn yesterday from the backrest of her desk chair. She pulled the shirt over her head, stretched once again and then decided that it was time to leave her room and look for breakfast.
When she opened the door, she was greeted by the smell of pancakes. Entering the kitchen, she quickly found the source of the smell. Her mother was standing at the stove, listen to radio and making pancakes.
When she turned around, she saw Lily and said: "Good morning sweetheart. You're up early, huh?"
Lily nodded and let out yawn before saying: "Yes. I forgot to close the blinds, so the sun woke me up."
"Well, tough luck," her mother said, "But now that you're awake, can you go to Sarah's room and wake her up? Then we can all have breakfast together."
Lily nodded and went off to her little sister's room. She slowly pushed down the door handle not to startle her sister, but as soon as she opened the door, this precautionary measure turned out to be unnecessary.
Sarah was sitting on her carpet, having a rather historically incorrect tea party involving a Barbie doll, a Brachiosaurus and her favourite stuffed animal, a little bunny. Lily smiled at the scene as her little sister turned around.
"Good morning," Lily said, "Mum asked me to wake you up so we can all have breakfast together. She's making pancakes."
"I'm awake," Sarah said.
"I can see that," Lily replied, "But can you put your tea party on pause, so we can have breakfast together?"
Sarah made a thinking face for a couple of seconds before nodding.
"Great. Do you want to get dressed and out of your diaper first?", Lily asked her.
She firmly shook her head and stood up from the carpet.
"Let's just eat together," the little girl said, obviously not bothered by the quite visible, wet diaper underneath her pyjama pants.
Lily took her by the hand and together, they walked back to the kitchen. By now, their mother had produced a stack of pancakes on a plate she had put on the dining table. She herself already sat there, waiting for the two girls to come. They both sat down at their usual places on the table, and their mother told them to take pancakes and whatever topping they wanted. Both girls did so, and while Sarah needed a little help from her mother to get her pancakes ready to eat, they all had a nice and relaxed breakfast.
Once they were finished, their mother cleared the table.
Then, looking at her daughters, she said: "I think we have to talk about something. As I've always said, nobody in this family needs to have secrets, we can talk about everything. So, is it okay for you if we talk openly?"
Both girls nodded and their mother continued: "Okay, then let's go over to the living room, it's cozier to sit on the couch, I think."
The three of them got up from the dinner table and walked over to the living room. They all sat down on the couch in a manner that they could face each other. This is how they sat whenever their mother said that it was time to talk openly.
"Alright," their mother said, "As I think all of us know by now, two of the three people on this couch wore diapers yesterday."
Lily couldn't help but turn red in embarrassment, even though both her mother and her sister already knew about it.
"I think," Lily said, "It's safe to say that two out of us three people are actually still wearing diapers right now."
"Are you?", their mother said, looking surprised at Lily.
Lily shrugged and said: "Well, I asked Sarah if she wanted to take off her diaper and get dressed before breakfast and she declined. And when I put my clothes from yesterday on, I thought 'Well, why not keep the diaper on until I shower', so yes. I'm still wearing a diaper and Sarah is, too."
"Well then," their mother said, "let's get straight to the point. I lay awake for a long time yesterday, thinking about the whole thing. By this, I came to the conclusion that I see no reason not to allow both of you to wear diapers. Well, as long as you want to, of course. I know that Lily wants to, but what about you, Sarah? Do you want to wear diapers during the day sometimes? Or are you too old for that?"
Sarah shook her head and then looked down to the ground, shily whispering: "I would love to wear diapers sometimes."
"Okay," their mother said, "then that's set. But if you're going to wear diapers during the day and use them on purpose, there have to be a few rules. Do you agree with that?"
Both girls nodded. To their surprise, their mother got up from the couch and told them to follow her. They went through the hall and upstairs, where their mother had her bedroom and her office. At the top of the stairs, they turned left into her office. Once all three of them were inside the rather tiny room, their mother pointed to the small whiteboard she had hung on the wall next to her desk to take notes.
"This is what I came up for so far. Please tell me if you're okay with these rules," she said.
On the board, written in their mothers tiny accurate handwriting, were the following rules:
1. Sarah's nighttime diapers will remain just that from now on. They will be used for nothing but her nighttime wetting.
2. I will buy one pack of diapers per month for both of you for recreational use. If this pack is empty, I will not buy another one. You are of course free to buy one with your own money.
3. You will only use the diapers to pee in. Of course, accidents can happen, but I don't want any of you to poop your diaper on purpose.
4. Lily is free to diaper herself. Due to previous events however, Sarah will be required to ask Lily or me to diaper her to prevent leaks.
5. For discretion, diapers should be worn only in this house. There may be exceptions like under Sarah's costume, but for the most part, you shouldn't go outside in your diaper.
6. Hygiene is important. When your diaper is changed, you will clean yourself/get cleaned with wet wipes. When you take your diaper off to change into normal clothing, you will take a shower. Lily will also be required to shave her pubic hair for hygiene reasons if she doesn't do so already.
7. It's your decision when to take off or change a diaper. However, if you misjudge the wetness of your diaper and leak, it's your responsibility to clean up the traces of the accident.
8. To prevent any effects on your potty training, you will not just pee your diaper as soon as you feel the urge to pee. You will wait until you really have to go.
9. There is no obligation for you to wear diapers, except for Sarah at night. At any other point in time, both of you can choose when to wear and when not.

Lily read those rules loud out to her sister, who couldn't read yet. Then, the three of them stood there in silence for a while.
"I think the rules are alright," Lily said after she contemplated what her mother had written on the board.
"Me too," her sister agreed.
Their mother nodded and said: "Well then, great. I'll write them down on paper so I can use my whiteboard for the usual stuff again. But as for you, Lily, I think we should get a pack of adult diapers for you to try out. Sarah's diapers do fit you, but they're rather tight, aren't they? I also think they won't absorb enough for a teenager to safely wear them without leaks."
"But mum, they're so cute," Lily protested.
Their mum thought for a moment, before she replied: "Alright. Why not do it like this: To start, both of you can get two packs of diapers. Sarah can choose both if she wants, otherwise I'll just buy the ones I usually buy for her. And for you Lily, we'll get one pack of diapers of your choosing and one pack of adult diapers, is that okay?"
The two girls nodded.
Their mother went on: "Great. Then let's see when we will buy them. Tomorrow after school? Or are you busy at that time already, Lily?"
Lily shook her head and answered: "No, I don't have much to do. The school year is almost over, there is no homework, so I'm free."
"Okay, then that's that," their mother said, "Let's go hit the stores tomorrow afternoon. It might be better if we go to tow, I don't think there are many stores that sell adult diapers in our little village."
Lily nodded and both her and Sarah got excited at the prospect of going shopping with their mother, let alone diaper shopping.
"Alright, now that that's settled," their mother said in conclusively, "You two girls can go about your day. Although I might have a favour to ask of you, Lily."
Lily looked at her mother a bit puzzled but said: "Yes? What is it?"
"Please take off your diaper and take a shower. I can smell it from here," her mother said.
Lily turned bright red and looked to the ground just like her little sister would do when she was embarrassed by something.
Then, she whispered: "Sure, I'm sorry."
"Oh, it's no problem," their mother said, "It's just that as I stated in the rules, hygiene is important, so please take a shower."
Lily nodded and the three left the office to go back downstairs.

Content: Just as a head-up and/or question:
I've written everything until about chapter 16 for now, but I think there are two options for the future. I'll either end the story sooner rather than later, or I'll take the story in a bit of a different direction. The latter option would mean using what I usually call "A writer's most boring feat", meaning a time skip of about three to four years. I've got some ideas in my head, but most of them include some kind of sexual theme, either underlying or in some cases more prominent, but I'm very much not comfortable with writing anything like this with an underage girl as protagonist of the story.
So as a question from my point of view: Would you rather like me to stop writing the story once I've reached said point, or would you want me to continue it after a time skip?

Content: Alright, after reading your replies, I'll probably write a sequel and link to it in this thread once this story is finished and I've posted the first chapter of the sequel. But for now, the next chapter:

Chapter 9
The next day and a half, Lily was continuously on edge. Anxiously awaiting the afternoon where her mother would take her and her sister shopping to get diapers, she sat in the classroom during the last period, nervously twitching with her right leg. The teacher was writing something on the board while talking monotonously about soil erosion and its connection with global climate change. She yawned while looking at her watch, realising that there were still more than 30 minutes left. How could this be? How was it possible that one Geography lesson in the last period felt ten times as long as a cozy evening at home with a good book?
"Lily," Laura, the girl next to her said, "Can you keep you leg still? It's annoying."
Lily, taken out of her thoughts by this request, stopped twitching but didn't reply to her. She couldn't stand Laura and despised the fact that their Geography teacher sat them next to each other for this term. Lily was just glad that the term was almost over and that, once summer vacation was over, she hopefully wouldn't have to keep sitting next to the classes most annoying girl.
Laura however obviously wasn't satisfied with the fact that Lily didn't answer anything.
"Well thank you for stopping," she said, "But do you know what would be much better? If you wouldn't do annoying shit like this to begin with. But hey, you're probably not intelligent enough for that, are you?"
Lily sighed and replied: "Do you know what you really be much better? If you would just shut it."
Laura looked at her and wanted to reply something, but at that moment, the teacher turned around and said: "Laura and Lily, quit it! Or do you want to get detention on the last week of school?"
Laura stayed silent and Lily couldn't resist to put a cheeky smile on.

***
When the lesson was finally over, Lily decided not to give Laura any opportunity to annoy her and packed her things as quickly as she could. She got up from her chair, slung her bag over her shoulder and walked out of the classroom as one of the first student. Then, she went straight for the main exit at which her mother would already be waiting with her sister in the car.
As Lily left the school building, the warm, fresh summer air greeted her. From where she stood, she could already see her mother's car parked at the side of the road opposite the gates of the school grounds. Smiling, she walked towards it and was almost there when she felt a tug on her shoulder. She turned around and saw Laura, who had grabbed the shoulder strap of her bag.
"I think we have to talk," Laura said, smiling viciously, "You can't just say something like that to me and think that you get away unscathed."
"What?", Lily asked, "That you should shut your big mouth? Yes, I can do so, didn't you notice? In case you didn't catch it: Just. Shut. It."
Lily tried to walk on, but Laura kept hold of her bag. Before she could say anything else however, Lily's mother had left the car and went straight for the two girls.
"How about you let go of my daughter's school bag?", she said, looking at Laura.
Laura, shocked by the sudden presence of and adult, let go of the should strap which made Lily jolt forward a little.
Then she turned around and looked at Laura before saying: "As I already told you, shut it. Stop annoying me, I never did anything to you."
Then, without awaiting any response, Lily went straight for the car, followed by her mother, who shot an evil glance at Laura before turning around.
Lily opened the passenger door and got into the car. Sarah greeted her from her child seat in the back and asked her what had just happened.
"Oh, nothing," Lily replied as their mother entered the car, "Just a girl that annoys everyone in our class, but specifically me, because I sit next to her in Geography and for some reason, she really dislikes me."
"Buh," Sarah replied and stuck out her tongue in the direction that Laura had stood just a minute prior.
Both Lily and their mother laughed about the little girl's reaction as their mother started the car and pulled out of the parking space.

***
About twenty minutes later, they arrived at the small shopping centre their mother wanted to take them.
As she parked the car, she told the two girls: "Do you know why I took you here specifically?"
The both shook their head, so their mother continued: "Because for one, we can have lunch here and for another, there's a huge drug store here that, if I remember correctly, should have diapers in all sizes, from new born to adult."
"Great," Lily replied, "But how about food first? I'm really hungry?"
"What about you, Sarah?", their mother asked her younger daughter.
"Whatever Lily wants," the little girl replied.
"Then it's settled, lets go and get something to eat", their mother concluded.
While their mother was busy getting a parking ticket, Lily unblocked her little sister from her car seat and helped her to get out of the car. Then, she took her by the hand, as her mother had told her many times.
When their mother returned, she had the ticket in hand and placed it visibly inside the car before closing the door and locking it.
"Well then," she asked her daughters, "What do you want for lunch?"
"Chinese?", Lily asked and pointed towards a small restaurant on the opposite side of the car park.
"No, McDonalds," her little sister said.
"Well, seems like we've got a disagreement there," their mother said, "But I think we'll go with Lily's suggestion, because I'm afraid there is no McDonalds anywhere near here."
"But I want McDonalds", Sarah started to cry, trying to shake off Lily's hand.
"Listen", their mother said firmly, "You either behave, eat with Lily and me and we buy diapers for you afterwards, or I'll rethink the whole thing. What about that?"
Sarah immediately stopped crying and looked shocked at her mother.
"Well, good thing we settled that debate. Let's get some food," their mother said.

***
Once they have had lunch, the three of them went over to the drug store their mother told them about. Much to both Lily's and their mother's surprise, Sarah didn't complain about the choice of food once after they got to the restaurant and ordered, probably because she noticeably liked the food. Now, they were walking through the car park and towards a store that Lily couldn't remember to ever have entered before.
The automatic doors parted in front of them and the air inside was quite cool, a pleasant change from the summer warmth outside. Lily looked around and noted that the store more or less seemed to be a scaled-up version of the drug store in their home town.
"Alright," their mother said, "Let's go find some diapers for you."
They went to grab a shopping cart and then started to look for the right aisle. First, they found the aisle where all the different brands and sizes of diapers for children were. Their mother grabbed one bag for Sarah's bedwetting, as they needed to restock on those anyway and then told Sarah to pick out another pack for recreational use.
The little girl stood around for some time until she decided to take a pack of Pampers Pants with the Paw Patrol characters on it. Their mother took it from the shelf and looked at it.
Then, she asked Sarah: "These ones don't have the indicator line on them, so we won't know when you're wet. You'd either have to tell us or we have to check regularly in other ways, are you okay with that?"
Sarah nodded and thus, their mother put the diapers in the shopping cart.
"Well then, let's get diapers for you Lily, shall we?", their mother said.
"Yeah. But don't you remember, we said that I get one pack of cute diapers like the ones Sarah wears and one proper pack my size. So let me look around and why don't you look for the adult sized ones?", Lily said.
"Okay. Should I take Sarah with me or can she stay with you?", their mother replied.
Sarah made any answer from Lily redundant by holding on to her leg and saying: "I'll stay with Lily."
Their mother smiled and nodded before going off, leaving Lily and Sarah with the cart to pick out a diaper pack for Lily as well.
Just as Lily looked around the different brands and sizes, a hated voice that she had heard less than an hour before came from behind her back: "What the hell are you doing here?"

Content: Sorry once again for taking so long, lots going on in both my private and professional life right now. I hope that all this will calm down over the next couple of days/weeks so I can start updating more regular again.

Chapter 10
Lily turned around to find Laura standing maybe two meters away from her, looking both angry and confused.
"I'm shopping with my family," Lily quickly replied, "And my little sister needed diapers, so we went here."
She pointed, first at Sarah and then at the contents of the shopping card, glad that there were no adult sized diapers in there yet.
"Whatever," Laura said, "Just get lost."
She turned around and attempted to leave, but Lily asked: "Anyway, what are you doing here, Laura. Especially in the diaper aisle? As far as I know, you've only got an older brother who has already moved out."
Laura turned bright red but didn't answer the question. She didn't need to however, as just seconds after that, Laura's mother came around the corner, a pack of large Drynites in hand.
"I found them, Laura. They were at the end of the aisle," she said, shaking the package in her hand.
"Interesting," Lily replied and took out her phone.
Before either Laura or her mother knew what happened, she took a picture of the two.
Then, she put on her sweetest smile before saying to Laura: "How about you leave me alone from now on? Because if you don't, then this picture will by some kind of freakish accident end up printed out and pinned to all the pinboards at our school."
"Fuck off," Laura replied, "I only need them because my period is so heavy that I bleed through everything else within half an hour. It's not like I'm a baby and pee in them or something."
Lily shrugged and said: "Well, from my point of view that's not what the picture says but sure, go ahead. Try it and explain to everyone at school how the bedwetting pants you mother buys for you aren't for bedwetting, I'm sure everyone will listen very carefully instead of just making fun of you."
Laura looked angrily at Lily and said: "Fine, fuck off. I'll leave you alone, but delete that picture right now."
"I'm afraid that's not how it works," said Lily, shaking her head, "If I don't have the picture, how could I be sure that you won't start to get mean again after summer vacation? But rest assured, as long as you're nice to me, the picture is in very safe hands and no accidents will happen. If you however decide to be a bitch to me again, I can't guarantee that the picture won't end up somewhere public."
"Fine," Laura said, still clearly angry, "Now fuck off."
Then, she rushed off, followed by her confused mother who still had the pack of Drynites in her hand.
Sarah looked at Lily with a mixture of confusion and curiosity, but before she could explain anything to her, their mother came into the aisle.
"Usually," she said in a stern voice, "I wouldn't encourage my daughter to blackmail someone. But in this case, and given that I know your stories about this girl and experienced it first hand when I picked you up, I think I should congratulate you."
Lily laughed and even though she didn't really know what all of this was about, Sarah joined in.
"Anyway, I found the aisles where the adult diapers are. Should we go there?", their mother asked.
Lily nodded and said: "Maybe we should wait and go to some other aisles until Laura is out of the store."

***
Once Lily had seen Laura and her mother leave, she decided to wait for a couple of minutes to make sure that they weren't coming back before looking for her mother. When she found her, both she and Sarah were looking at a range of small toys in one aisle.
Lily went towards them and said: "Alright, let's go and get diapers for me."
The sentence felt strange to say, but before Lily could think much about it, their mother said: "Alright, follow me," and went off.
About a minute later, they stood at the end of two long aisles that all seemed to be filled with adult diapers. Lily looked at it and felt overwhelmed.
"Good god," she said, "How should we ever find something here?"
"Soooooo many diapers," Sarah added and put her arms as far apart as she could to emphasize what she said.
Their mother shrugged and replied to Lily: "We could just start looking. Or ask an employee, I've seen one help an older lady to find the right thing just minutes ago."
Lily raised her eyebrows and said: "I think that would be too embarrassing for me."
"Why? No one knows you here, do they? And how else will you find the right thing? I don't want you to leak all over your furniture or something like that just because we picked the wrong product due to being clueless."
Lily sighed loudly and their mother added: "Maybe this whole thing wasn't that good of an idea after all. If you're that ashamed, we probably shouldn't get diapers for you."
"No," Lily said quickly, "Alright, let's ask an employee. If that's the only way, I'll do it."
"Great," their mother replied, "Then let's find someone who can help us."
They didn't have to search for long, as on the other end of one of the aisles they found an employee who was helping an older man to find the right incontinence pads for his wife. Once he was done, they approached him.
"Can I help you?", he asked the three of them.
"Yes, you actually can," their mother replied, "But can you please keep it down so no one gets embarrassed?"
He nodded and said: "Sure. Discretion is very important to many of our customers and we aim to provide you with the best possible service in that regard. If you want, you can follow me to our discrete consultation room."
Their mother looked at Lily, who nodded and so the three followed the man. He went around a corner and opened and inconspicuous door between two shelves that had a sign on it saying "employees only". He turned on the lights and they followed him.
Inside was a spacious room with a table with a laptop on it and four chairs around it, two changing tables, one kid- and one adult-sized and a small area of toys. The employee closed the door and pointed to the toys.
"Why don't you go and play for a bit?", he asked Sarah.
The little girl looked to her mother for approval, who nodded, and then went over to the corner to play.
"Okay," the employee said, "How can I help you?"
Before Lily could answer anything, her mother already started to talk: "This is my daughter, Lily. She's recently developed a problem with bedwetting and the usual products for teenagers don't seem to be absorbent enough, so we decided to get adult diapers. However, we were overwhelmed by the sheer number of brands and sizes when we got here."
The employee nodded and said: "Yes, if you're not familiar with the topic, the choice can be quite difficult and overwhelming at first. But that's what we're here for. First of all, how about we measure your daughter so we know which size she needs?"
Lily looked at him a bit disturbed and he quickly added: "Don't worry, just the circumference of your hip, nothing else. You can leave your clothes on and everything, I just need you to stand up for a second."
Lily got out of her chair and the employee produced a tape measure. Carefully, he put it around her hip, pulled it reasonably tight and then read the measurement out loud.
"77cm," he said, "How old are you, if I might ask?"
"Fifteen," Lily replied, annoyed at what she knew would come next.
"Oh, it seems like I hit a sore spot there, I'm sorry. I just wanted to know because even though some teenagers are smaller and some taller, for most, the bladder capacity depends on age rather than size. So, I need to know you rough age to know which absorbency you need", the employee responded.
Lily nodded and sat back down again while the employee typed something into the laptop.
"Alright," he said after about half a minute, "Looks like you're right in the range of the size 'small' for most brands. And given that you're fifteen, I probably know the problem with the bedwetting products you tried so far."
Then, he started to explain in much detail how most companies gear their products towards a certain age range, but due to cost effectiveness optimize it for the middle of said range rather than the top or bottom end of it.
Once he was done, he concluded with: "And that's probably why the normal products like Drynites or Ninjamas leaked, because they're geared toward the amount of urine a 10-12-year-old wets during the night, not someone who's fifteen. Anyway, let's see if we can find something for you."
He scrolled on his laptop for a brief moment, and then continued: "From my experience and from the ratings our customers are giving the product, I would recommend you to either get Super Seni Quatro or iD Slip Maxi. These are the most absorbent products from both manufacturers, but given the fact that your ideal size would be small, you should use those as the smaller sizes tend to have less absorbency."
Lily felt a bit overwhelmed, but her mother responded: "Well, which of one should we get then?"
The employee replied: "From what I've heard and from what our customers say, they're both equally good. Maybe take a look at both of them and take the ones Lily likes better?"
He turned around the laptop and it showed a comparison of two adult diapers. Both were white, but one had two reddish-pink stripes with 1s printed on it running down it's length and the other one had purple stripes running down it, interrupted every couple of centimetres by the letter S. Both had the name of their product on it and both had some variation of the wetness indicator lines that Lily already knew from Sarahs diapers. Lily thought for a moment and then pointed at the left side of the screen.
"Okay, Super Seni Quatro then. I can show you the isle where you can find those, if you want me to," the employee said, turning the laptop back around.
Lily nodded and they all got out of their chairs, with Lily's mother saying: "Come on Sarah, it's time to pay and go home."
Sarah nodded, put the toys she was playing with down and went over to her family. Then, together with the employee, they left the room and went back into the store.

***
As promised, the employee showed them the aisle where the diapers were and even showed them the correct ones.
Their mother looked at it confused and said: "How should I ever going to find my way around here?"
"Don't worry, it comes with time," the employee responded, "But if you're having trouble, you can always ask one of us. Of course, best of all would be if the need for those diapers would be omitted before you can get used to it, wouldn't it?"
Lily nodded, sticking to the story her mother had spontaneously made up.
"Lily, Sarah, would you mind getting our shopping cart?", their mother asked.
In response, the two of them went to where they left the cart and took it over to the aisle where they were now standing. Once they arrived, the employee put a pack of the diapers Lily chose in the cart before asking the three if they needed any more help.
"No thank you," their mother replied, "You've been very helpful and kind."
"My pleasure," the employee responded, "One small piece of advice from my side: When you're paying, you can get a large, opaque plastic bag so you can take your purchases home discretely. Just ask the cashier about it, they all know."
They thanked the man and went on their way to pay and leave the store. Once they arrived at the register, Lily looked around anxiously, but couldn't make out any trace of Laura or her mother. Thus, they put everything on the checkout counter and their mother paid for it. When she asked, they got a very large, opaque bag, just like the employee said. Lily quickly put everything inside before they left the store to get back to their car.
When they exited the store, just as Lily felt relatively safe, she spotted Laura sitting at an ice cream parlor just a couple of metres from the exit. When Laura saw them, she quickly got out of her chair and went over, trying to peek into the bag Lily was carrying.
"So what did you get after all that time in there, huh? Diapers maybe, because you're not only the size of a baby, but an actual baby? Why would you get a non-transparent bag otherwise?", Laura asked, trying to get a glimpse of what was in the bag.
Before Lily could react to this in any way, her mother said: "How about you go back to your mother and leave us alone? Yes, we bought diapers, for my little daughter Sarah, who is very ashamed that she still needs them at night, that's why the bag isn't see-through. As for the rest, I think my daughter just talked to you about it inside the store, didn't she?"
Lily pulled her phone out of her pocket and showed Laura the photo she took.
"Remember," she said, "Be nice to me or I can't guarantee that this photo will remain private."
"Fuck off," Laura said and went back to her mother.
Lily, Sarah and their mother went back to the car, their mother shaking her head about Laura.
"What is wrong with her?", she said, more to herself than to her two daughters.
"Nobody knows," Lily responded, "We have teachers who tried to find that out for years now. She isn't even stupid or something. She's just behaving like that all the time."
Their mother shook her head, while they loaded the car and all sat down, Lily helping her little sister to get into her car seat and strapping her in.

I just have one request - stop apologizing! We are enjoying your story very much but we all understand you have a life beyond just writing it. We know you aren't slacking off, so it's cool if it takes longer than expected between chapters.

[End of quote]

Mate, I'm German. It's engraved in my DNA to apologize for being late

Content: Thanks for all the replies and the suggestions, but due to the fact that I'm always a couple of chapters ahead, I won't be able to consider them in the context in which they were made.
Anyway, here's the next chapter:

Chapter 11
Once everyone was strapped in and they got going, Lily realised how on edge she had been ever since she had seen Laura in the store. Now, she suddenly felt much calmer as her mother steered the vehicle towards the motorway entrance.
"I really didn't expect her to be there," Lily said, more to herself than to her mother or her sister.
"Well," their mother responded, "Things happen. Expected or not, I'd say it turned out quite well for you, didn't it?"
Lily nodded and replied: "Yes. Maybe she'll actually stop annoying me at school now. I can't imagine that she wants everyone to see that photo, regardless If she wears the Drynites because of her period or for bedwetting."
"If something like that would've come out when I was in school, that would probably have meant social death for the person on the photo. Everyone would make fun of them and no one would want to have anything to do with them," their mother responded.
Lily nodded. For the rest of the ride home, they talked about other topics, mainly the ever-nearing summer vacation and their planned holiday in two weeks' time. The ride felt disproportionately long for Lily, who just wanted to get home and try out her new diapers now that she got over the shock of meeting Laura at the store.

***
Much to both girl's dismay, their mother had decided to get groceries on the way back. When they finally arrived at home, Lily felt like an eternity had passed since they bought the diapers. After their mother had parked the car on the yard, Lily wanted to grab her diapers and head straight to her room, but her mother stopped her.
"Come on, help me to get the groceries out of the car. And once that's done, we have to have a little talk regarding diaper wearing before you can put one on," she said.
"I thought we already had that talk on Sunday?", Lily replied while picking up one of the grocery bags from the cars' boot.
Her mother nodded and replied: "We did, yes. But I've done some more research and I want to talk a few things through with you. Don't worry, it won't take long."
"Alright," Lily replied and helped her mother carry everything from the car to the house, except for a small bag full of different fruits that Sarah got to carry after complaining that she was left out.
Once they were done storing the groceries away, their mother took all the diapers they had bought out of the plastic bag they had gotten at the store. First, she stashed the baby diapers under the changing table in Sarahs room, except for the package that Lily choose for herself.
With these two packages, one with Pampers diapers and one with the Seni diapers in Lily's size sitting in front of them on the couch, she asked Lily: "So, where should we store those?"
Lily shrugged and said: "I think there should be enough space in my wardrobe."
"Are you sure?", her mother replied, "Maybe if you have friends over, they'll see it."
Lily shook her head and said: "No, none of my friends have ever looked inside my wardrobe. I'll just put them where I hang my trousers and no one will ever see them."
"Okay, if you're sure, do it. It's your decision after all," she replied. Then, she looked at Sarah before adding: "Sarah, can you play for yourself for a minute? I have to go talk to Lily."
"TV please," Sarah responded.
With a sigh, their mother turned on the kids' channel on TV. Sarah sat down on the couch and started to watch the screen.
"Well, let's go to your room, Lily," their mother said.
Lily nodded and the two went over to Lily's room, her mother carrying both diaper packages. Once inside her room, Lily closed the door behind them as her mother put down the diapers.
"Will you give me a second?", her mother said, "I have to get something."
Lily nodded and her mother left the room. Finally, being able to take a closer look at what they had bought, Lily grabbed the pack of adult diapers and studied the print on it. It contained information about the type and size of diaper, as well as the absorbency level in comparison to other products of the same brand. Impatiently, Lily ripped the pack open at the marked spot. The plastic split evenly in half and revealed the neatly folded diapers on the inside.
Lily picked one and tried to take it out, surprised by the amount of force needed to do so. When she managed to get it out, she looked at it all around before folding it open, studying it from both sides. The diaper was soft and mostly white, except for two reddish-pink stripes on which the number one was printed, just like in the picture the man at the store had shown her. Down the middle ran two parallel yellow lines with the name of the diaper and some numbers printed in between them. The smell the came from the fresh diaper reminded her of the diapers she wore when she was a child, it was almost eerily similar. As she ran her hand over the diaper, she felt a not unpleasant tingling in her stomach. Before she could do anything else however, her mother returned, a small cloth bag in hand.
"Oh, you've opened them already," she said when she saw Lily with the diaper in hand.
"Yeah, I was curious," Lily replied.
"Alright," her mother said, "Then get down on your bed please, and take off your trousers and your underwear."
Lily looked at her mother with an alarmed expression.
"Why?", she asked.
Her mother sighed and replied: "As I said, I've done some research. Please don't make this any more difficult than necessary, Lily. The last thing I want to do is to take my fifteen-year-old daughter to the gynaecologist because she's got a diaper rash. It's important to take the right precautions, so I'll show you once how to apply barrier cream in the correct way and then I'll diaper you. Once I'm done, you can do it on your own, but it's important for you to know how to do it the correct way."
Lily, knowing her mother and hearing from the tone of her voice that there was no point in discussing this with her, sighed. Then, she took off her jeans, put them beside the bed and lied down. Next, she pulled down her slip and kicked it away. It landed perfectly on the backrest of Lily's desk chair and both her and her mother laughed at the fact.
Once Lily was done undressing, her mother took some things out of the bag she had brought with herself.
Then, she took a quick look at Lily's private parts and said: "If you really want to wear diapers more often, you should probably get rid of your pubic hair. I've read on multiple websites that it's more hygienic to not have hair… down there when you're wearing diapers."
Lily turned a little red, but replied nothing. Her mother meanwhile placed a small mirror at the foot end of the bed, explaining that this was necessary so Lily could see where to apply the barrier cream. Then, she took out a tube of said cream before completely unfolding the diaper that Lily had taken out of its package just minutes before. Once it was unfolded, her mother fluffed it up.
"You should do this before you put a diaper on," she explained to Lily, "It will make for a better distribution of the absorbent material and thus, the absorbency will be better."
Lily nodded.
"Okay, bottom up, Lily," her mother said. Then, she added: "Good lord, I don't remember when I last said this."
"Me neither," Lily replied, lifting her bottom of the bed so her mother could place the diaper underneath her.
Her mother moved the diaper from side to side a bit, until she was satisfied with how Lily lay on it. Then, she squeezed a good amount of barrier cream onto her finger and told Lily to watch as she applied it. Lily didn't really feel well as she felt her mothers' hands in her private area for the first time in years. However, she watched as she was told, eager for this to be the only time for her mother to do this. Once she was done, her mother smeared the remaining cream on her finger on the inside of the diaper. Then, she looked at Lily with an expression on her face that seemed somewhat disappointed.
"Lily," she said, "You're fifteen. I really thought by now you knew how to wipe properly when you peed."
"What?", Lily replied, "I always wipe properly. And I haven't been to the toilet since before you picked me up at school and it's been hours since that."
"But you're… lady parts were damps when I put the cream on," her mother replied to emphasize her point.
Lily combined this information with the tingling in her stomach just minutes before and her face turned bright red. She didn't respond anything, but her mother, realising what the origin of the dampness was, turned red now, too.
"Listen," she stuttered, "I'm sorry, Lily. I didn't want to interfere with your privacy or embarrass you or anything."
Lily shook her head and muttered: "It's okay, mum. It's not your fault. Now can you please finish diapering me?"
Her mother nodded, feeling at least as embarrassed as her daughter. She grabbed the front of the diaper, pulled it up and taped it shut with the expertise that one gathers from changing hundreds and hundreds of diapers. The only difference was that these diapers had four tapes instead of two. Once she was done with that, she asked Lily to spread her legs a little further. Lily did so and her mother made sure that the leak guards were positioned properly.
Then, she grabbed the mirror and the barrier cream, put it back in the back she had brought them in and said: "Alright honey, that's it. Again, I'm sorry, it wasn't my intention to embarrass you."
"It's alright, mum," Lily responded while getting up from her bed, "Just let's don't ever talk about it again, okay?"
Her mother nodded and said: "Alright. But I have to repeat what I said on the weekend, you do look very cute in a diaper. Almost like when you were a toddler."
"Thanks mum," Lily replied, her voice soaked in sarcasm, "That's what I need to hear, given that I feel like shit all the time anyway because I'm so much smaller than all my peers."
"Oh my god, sorry, honey," her mother said and hugged her.
"It's alright," Lily said, "But can you please leave me alone now? I want to get used to the feeling of wearing such a big diaper."
"Sure honey," her mother said and left the room.
Lily waited for the door to close, then she got in front of her mirror, pulled her shirt up a bit and looked at herself in the adult diaper from all angles.
