The Ageplay Club: Studying Human Behavior

(Another entry in the Ageplay Club series! Check out other stories in this series to understand what's going on here, but otherwise, enjoy!)

    “Alright, class is dismissed!”

    Rising from her seat as the last bell of the day rang, the ‘young’ girl by the name of Lavenza grabbed her bag and began to leave. Her first day of school had gone about exactly as she had expected it, and it was hardly a challenge for someone like her. After all, though she looked young, she was in truth an attendant of the Velvet Room, and therefore had lived many times longer than everyone else here, including the faculty.

    To that end, she knew much more than most here...in terms of technical things, that is. The sciences, maths, even stuff like literature and legends she knew well enough. After all, most of that was absorbed into the collective consciousness of the world, and so she learned by proxy. What Lavenza did not know, however, were what these humans normally did. In fact, that was what she was here for.

    Elizabeth and Margaret, her two elder sisters and also attendants of the Velvet Room, had given her a simple task. Enroll in a local school and learn more about humans so she could gain a better understanding of them. Of course, she had the guest that she saw often, but that was just one person. Surely not enough to get the level of understanding she desired. So Lavenza had enrolled in this school, but she found it exceedingly difficult to actually make a bond with anyone so far. Apparently it would need to take time...but she had heard of a way to help speed up that process.

    A club. A place composed of people with similar interests, and more importantly, a place that would keep her within close proximity of multiple people so she could learn about their behavior and what they were like. At this point, the only question was which one to join. A tricky question when there were so many!

    “So many interesting clubs...but I haven't found one that quite peaks my interest yet.” Lavenza muttered to herself as she wandered the halls of the academy, peaking into every club room she passed by. There were plenty of them, and for all different kinds of purposes. Even still, none seemed to really grab her, a problem when the options seemed like they were running out. There had to be more…

    Deep in thought, the blond-haired girl managed to accidentally wander her way towards an almost entirely unused section of the building. Once she realized where she was, she prepared to turn back, but was stopped when she heard something. Voices...a lot of them. It didn't take long before she found the source of the noise, right behind a door that led into a long abandoned classroom.

    “Perhaps it's a club…” Lavenza muttered to herself, and wanting to see everything this school had to offer, began to walk right up to the door and grabbed the handle. Without a moment of hesitation, she pulled it open and peeked inside. What she saw behind the door was...certainly something she had never expected to see. Namely, a bunch of girls wearing...diapers and clothes meant for infants? 

    Not just that, but playing with all manners of toys as well! Lavenza would have certainly mistaken them for babies if not for their size. Just...what was this place that she had stumbled upon?

      Slowly walking into the room, Lavenza continued to look around, but then silence fell across the room as the girls inside realized that someone else had just entered. “Oh, hello.” Lavenza said, waving to the group of eyes staring at her awkwardly. “Forgive my sudden entrance, but… This is a club, yes?”

    “Oh, umm, well...yeah, I suppose you could say that…” A girl with blond hair named Kaede said as the other girl walked into the room. “Are you, umm...new to this school? I don't think I've seen you around…”

      “Ah, yes, I am.” Lavenza said, realizing she had skipped introductions due to her fascination with the scenario she had just walked in on. Giving a curtsy to the other girl, Lavenza made sure she sounded as respectful as possible. “It is very nice to meet you. My name is Lavenza, and I started attending this school just today.”

    “Well…welcome to the school then.” Kaede said, stepping up as leader of this whole thing and awkwardly smiling as she had the other girl come in closer. When someone entered this room, to make sure the secret wasn't spilled, they had to become a part of it...which would apparently apply to this new girl too. “My name is Kaede, and you could say I'm the...leader of this club. Were you looking around for one to join…?”

      “Yes, actually. And I’m running low on options…” Lavenza admitted, thinking back to all the other clubs she had seen today, and how none of them had grabbed her attention. This one seemed rather interesting, though… “Do you think, perhaps, I could join this one?” She asked, hoping for the best.

    She was...already interested? Most new attendees had at least some initial reservations about joining a place like this, but she wanted to come and join right away? Odd...but certainly not something to be complained about. “Of course! You can join if you'd like! Just...one rule. Don't tell anyone outside this club about this, okay?”

      Don’t tell anyone outside the club? Why not? Surely if this was a club, the school had to have known about it, and that meant it was normal for humans to do, right? However, Lavenza didn’t want to risk being rejected from the club for not adhering to the rule, so she nodded. “Yes, of course. I won’t tell a soul.” Besides her sisters, probably. “Now then, am I correct in assuming you need… a certain attire to be a part of this club?” She asked, looking at the other girls who were all dressed in infantile outfits.

    Before Kaede could go ahead and open her mouth again, another club member stepped up to explain...a rather excitable one too, at that. “That's right!” Yukiko said with a grin as she pointed towards the changing room they had. “There's plenty of outfits back there for you to put on, and I'll help you choose!”

      Lavenza smiled at the girl’s hospitality, and nodded at the offer, bowing respectfully towards the girl as well. “I would greatly appreciate that. Thank you for your assistance.” She said as she began to walk towards the room the black-haired girl had pointed towards.

    Yukiko led her there, and once inside, revealed a room filled with a multitude of different, infantile outfits...alongside plenty of diapers, of course. “Alright, undress and I'll get you into a nice, thick diaper.” Yukiko said with a smile as she began to go and grab one.

      While Lavenza wasn’t exactly up to speed on human societal norms, she was fairly certain that anyone would be embarrassed to suddenly be told to remove all their clothes. However, that was what she was told to do, so it wasn’t like she could refuse… Stripping off her long, blue dress, Lavenza laid down on a nearby changing table.

    Once Lavenza laid down, Yukiko walked over with the diaper in hand, beginning to slowly remove the girl’s undergarments before sprinkling on baby powder and taping the diaper up around her waist. It was light blue in color, with a butterfly pattern adorned across it…more fitting than Yukiko could possibly know. “There, doesn't that feel comfortable?”

     Lavenza looked down at her new thick underwear, poking it a couple times as she did so. “Yes, it is… rather comfortable. Thank you for helping me change.” She said as she began to hop off of the changing table. “Now then, what other clothing do I need to wear?”

    After looking between a few different outfits, Yukiko eventually held up a frilly, dark blue dress, perfectly sized for Lavenza. Well, even if it wouldn't cover her diaper up at all. “How about this?” She asked while holding it up.

      The dress that the other girl had held up looked like a more infantile version of the dress Lavenza usually wore, so she had no problems with the offered attire. “That looks fine to me.” She said, reaching forward to take it from Yukiko so she could put it on.

    However, Yukiko didn't dare hand the dress over to Lavenza. “Babies don't put on their own outfits, you know~” She said with a smile, having the smaller girl raise her arms up before promptly pulling it onto her, stepping away once she finished doing so. “You look adorable!”

       As soon as she was fully dressed, Lavenza went over to a nearby mirror that had been set up in the changing room and looked over her new attire. “I… Certainly do look cute…” She muttered as she looked over herself from every angle. “Thank you for picking this outfit out for me.”

    “You're welcome...now why don't you go back in there and begin playing, huh? I'm sure that the rest of the girls would be happy to give you some pointers on how to act like a real baby.” Yukiko said with a giggle.

       Lavenza simply nodded and began to head out into the main room once more, awkwardly waddling thanks to being unfamiliar with the feeling of thick padding between her legs. “Well, I suppose I should get started now…” She said out loud to nobody in particular. “But where should I start?”

    Suddenly, the girl’s attention would be caught by a few girls waving her over...a bunch of familiar faces, at that, though it was unlikely that they really knew who she was. “Hey, over here.” The voice of Makoto Niijima said while looking at their newest member.

      Lavenza walked over to the other girls, recognizing them as friends of her guest. Of course, none of them would recognize her in kind, but that didn’t matter much. Seeing familiar faces around here just reaffirmed her belief that participating in this club was normal. As she sat down next to the group, she smiled a little bit. “Hello, everyone. Are you enjoying your club activities today?”

    Nodding her head, Haru spoke up next, holding out a doll towards Lavenza. “We certainly are. Since you're new...would you want to try playing with this?” She asked while handing her the doll.

      Lavenza nodded in response, taking the doll into her hands with a soft smile. “I would be happy to.” She said as she began to make the doll dance around a bit, humming music to herself as she did so.

    Lavenza really had taken to all of this fast. The other girls there all smiled as Lavenza played, Makoto grabbing a doll of her own and moving it over towards the other girl’s. Quickly she made it dance around as well, playing along with whatever scene was playing out in Lavenza’s head.

      Lavenza hardly even noticed that Makoto had joined in her playtime, far too caught up in her own little world as she continued to hum to herself and make her doll dance around without a care in the world. This was far more fun than she had expected…

    “She's already gotten quite used to this.” Haru said with a smile as she looked over towards Makoto, who herself had gotten more than a little into her playtime. It was adorable...so adorable that she had to join in herself, grabbing a plush rather than a doll.

       “She really has… It’s crazy how quickly she just accepted this.” Futaba chimed in, simply watching the playtime for now, not partaking in it herself. “Maybe she’s just into this stuff normally, and this club gave her the opportunity to have fun with it?”

    “That certainly seems possible…” Haru replied while moving her plush around, giggling as she had it interact with some of the other toys. Mostly Makoto’s, since Lavenza herself seemed far too preoccupied with her own playing.

      Lavenza eventually finished the song that she was humming, finishing her doll’s dance with a flourished pose and grinning. “That was much more fun than I expected. I can see why this club is so popular.”

    “Yes...popular.” Makoto repeated. In all honesty, the club had grown to a rather considerable size...and with Lavenza joining, it just kept getting bigger. Even if it was a secret, this club could be considered popular in a sense. “But I'm happy to hear you're having fun.”

      “I certainly am. This club was absolutely the right choice for me to join.” Lavenza said with a smile as she reached forward to pick up a rattle, beginning to shake it happily without a care in the world.

    As Lavenza began to play with the rattle, another girl went to go up and play with her. Someone rather unexpected too...Satsuki Kiriyuin, who Lavenza would recognize as that serious looking girl she earlier saw walking through the halls. Nonetheless, she grabbed a rattle of her own and began to shake it as well.

     Lavenza was surprised when the serious-looking girl suddenly came up to her, but she didn’t object at all, instead just continuing to shake her rattle with a smile on her face. “I hardly expected someone like you to be in this club as well.”

    “Well...let's just say that there are all kinds of people in this club.” Satsuki said, smiling ever so slightly as she shook her rattle, beginning to get into a more infantile mindset.

      “I can see that. It’s quite the popular club, it seems.” Lavenza said as she looked around the area once more, seeing all the girls enjoying their time in the club. “I’m very excited to be a part of it.”

    “We’re always happy to have new members.” Satsuki replied in turn. It seemed like there was a never ending supply of students they could recruit for the club, and she had a feeling that in no time almost the entire school would be in on it… As if that could ever actually happen.

      “Well, I hope I live up to your expectations of how a new member should be.” Lavenza said, smiling at Satsuki as she continued to play with her rattle. While playtime was rather fun, Lavenza had to assume that there was more to the club than just this…

     Something that would be proven when one of the club’s resident caretakers walked up towards Lavenza. “Are you hungry?” Kirumi asked while looking down at her, giving a soft smile to their new member.

       Lavenza was caught a bit off-guard as one of the other girls came up to her, asking if she was hungry. The girl in question wasn’t wearing any sort of infantile clothing, so she could only assume this girl was here to attend to the needs of the other club members. “Ah, I suppose I could eat, yes.” In truth, Lavenza had no need for food, but she didn’t want to be rude by declining the offer.

    Once she heard confirmation, Kirumi promptly lifted up Lavenza, something remarkably easy given her small size, and carried her over towards one of the highchairs set up in the room. In the one right next to her, there sat a black-haired girl...one that seemed to be smiling, although Lavenza could tell that it was forced…

       Lavenza was rather confused about the expression of the girl sitting next to her, so she decided to make small talk while she waited for whatever food she would be eating to be brought to her. “Ah, hello… Are you enjoying your club activities today?” She asked.

    “Yes...of course…” Maki said, though straining herself a little to say such a thing. This situation she had found herself in was less than ideal, but for now she just had to continue pushing through with it… “You seem new here...welcome…”

      Lavenza could tell that the kind words were practically forced out of the girl’s mouth, but she smiled anyway. “Yes, I am new. I just joined this school and this club today. I look forward to continued participation in both. How long have you been a part of this club?”

    “Quite a while, actually. Though, not always like this…” Maki muttered, before suddenly peeking up the moment that Kirumi came over with two jars of baby food. “Mommy! I was just talking to our new member.” She said, apparently quite eager to be cheerful now that the maid was within sight.

    “Really? I hope you become good friends with her. Perhaps I could even organize some sort of play date outside of the club.” The maid said with a soft smile, before turning towards Lavenza and setting down one jar of baby food on the highchair’s tray.

      Mommy? So these two girls were acquainted outside of the club… She would have to keep a mental note of that. However, her focus was soon broken as the jar of baby food was placed on the tray of her highchair, and she looked down at it with a curious expression. “Is this what I’ll be eating?”

    Nodding her head, Kirumi lifted the lid off of the jar and picked up a spoonful of it on a plastic spoon, beginning to gently move it over towards Lavenza’s lips. “That's right, so open up and I'll feed it to you.” She explained.

      While Lavenza was a bit confused as to why she wasn’t allowed to feed herself, she didn’t question it, instead just opening her mouth as she was told for the first bite of baby food. And once she ate it, she was surprised at how sweet it was. Was this what babies usually ate? She was missing out, if that was the case… As soon as she swallowed the first bite, she eagerly opened up for more.

    After confirming that Lavenza did indeed like the food, Kirumi wasted no time in getting another spoonful of the sweet mush and moving it over towards Lavenza’s mouth again. “I'm happy that you like it.” She said as she placed the plastic spoon in her mouth.

       Lavenza ate up the second bite with just as much enthusiasm as the first. Since she didn’t actually need food, she could eat as much as she wanted without a care in the world. So she continued to open up her mouth for more and more until eventually the jar had ran empty. A fair bit of the food had found its way stuck to Lavenza’s face, but she didn’t seem to care. “Thank you very much for feeding me.” She said with a smile.

    “You're welcome.” Kirumi replied, before grabbing a rag and beginning to clean up Lavenza’s face. After she managed to get all of the mush off of it, the girl being surprisingly still all the while, she proceeded to then grab a bottle and hold it up to the girl’s lips. “Now, here's some nice milk to wash it all down.”

       Lavenza stayed still as her face was wiped up, trying to stay calm and respectful so she could leave a good first impression for the rest of the club. As soon as the bottle was placed in her mouth, she wasted no time in sucking on it happily.

    Leaving the girl to drink the bottle on her own, Kirumi moved on to begin feeding Maki, a task that had become rather simple over time. She really was a well behaved baby now...even if that was just because Maki knew that doing so would get her the best treatment.

      Lavenza continued to drink from the bottle happily, even sucking on it after the milk had run empty because she found the experience pleasurable. However, she eventually spit out the bottle regardless, and set it down on the tray before turning to the caretaker. “Excuse me. I believe I’m finished with my meal now. May I please go back to playing?”

    “Well of course.” Kirumi said as she lifted Lavenza out of the highchair and placed her back down into the floor, sending her off with a smile as she finished feeding the other girl. “Just tell me if you need anything, alright?”

       “I certainly will.” Lavenza said with a smile, beginning to crawl over to the pile of toys once more (she found crawling was a much more effective method of movement with the padding between her legs). Once she got to the toy pile, she grabbed a rattle… but also grabbed a plush, looking between the two with an intense expression of concentration on her face. They both looked so appealing, how was she to decide which one to play with first…?

    It was certainly troubling, so much so that Kaede could tell that something was wrong as she waddled over to check on her. “Lavenza? Are you alright?” She asked, before looking at the two toys in her hands. “Having trouble deciding what to play with?”

      “Yes, I am…” Lavenza muttered, still looking between the two toys with the same concentrated expression. “Both of these toys look so enticing, I can’t decide which I’d rather play with first…” She muttered.

    “Hmm, that certainly is a problem...but you can just go ahead and play with both.” Kaede said, mainly referring to the fact that she could just randomly choose one and play with the other after.

       “You’re right, I certainly could.” Lavenza said, beginning to focus once more, but this time on something different. Her whole body began to glow, and in a burst of blue light complete with ethereal butterflies flapping away, Lavenza…

     ...Had suddenly turned into two separate, identical-looking girls, each one wearing an eyepatch and a large blue hat. In place of the infantile dress Lavenza had been wearing, the two girls were wearing dark blue onesies, with a diaper bulge clear around their waists. “I’ll be playing with this rattle, thank you very much! Justine, you can play with that plush.” The girl with her hair in two tight buns said as she began to shake the rattle.

    “That's the one I was hoping to play with anyways, Caroline.” The one apparently named Justine said as she picked up the plush and alternated between making it dance around and hugging it tightly.

    Meanwhile, the whole room grew so silent that the shaking of Caroline’s rattle could be heard all the way from the other end. Wide-open eyes stared right towards the two… Well, were they two? Or one? It didn't make sense, and none of them could believe their eyes. Was this some kind of illusion? A magic trick? A prank their new member was pulling on all of them? None knew the answer, and they could hardly find it within them to even speak up and comment about what had just happened.

    Well, except for one of them. “Oh, this is great!” Yukiko exclaimed, hardly appearing fazed by the whole thing. Sure, this was strange, but there was something far more important to focus on. “Now we have two new club members instead of just one!”

       Caroline hardly paid attention to Yukiko’s excitement, instead being more focused on the fact that everyone else was staring at them. “Hey! What are you punks looking at?! Get back to what you were doing!” She shouted, slamming her rattle against a wall to achieve the same intimidation effect as her usual electric baton. “Stop staring at us, weirdos!”

    “Yes, we really would prefer if you would stop staring. I was under the impression we were to be treated as normal club members.” Justine replied, much more calm than her twin had been, but no less annoyed with all the glances that were being thrown her way. “Really, such a strange group…”

    While everyone else was still utterly confused about what had happened, and rightfully so, being told off by the two girls made them begin looking away as told. What they had seen was utterly impossible...but it wasn't as though stranger things hadn't happened.

       Once all the weirdos finally stopped staring at them, Caroline went right back to playing with her rattle, a cocky, satisfied smile on her face. “I can see why these humans love this stuff so much! This is great!” She said, shaking the rattle as if it was the most interesting thing in the world.

    “These humans do have such interesting toys. In fact, I'd say that we've been missing out all this time. We should have come sooner.” Justine replied, still hugging her plush and making it move around, before grabbing another and having them interact with making her own fantasies.

       “I agree! We’ll have to come to this club every day from now on! No exceptions!” Caroline responded boisterously, laughing to herself as she continued to shake the rattle. However, her complete lack of concentration on anything except the rattle bit her in the ass when suddenly a hissing noise filled the air, and Caroline’s diaper began to grow warm and wet. Not that she noticed…

    However, the far more perceptive Justine did notice, and it didn't take her too long to realize what it might have been. Mostly because she heard the same sound coming from a few other girls since she had been here. “My, my. Did you wet yourself?” She asked in a rare teasing tone. “Perhaps between us I'm the big sister after all…”

      Caroline was finally brought back to reality as Justine spoke to her, and she looked down at her diaper with a large blush on her face. “I-I did not! That sound was probably just you wetting yourself, and now you’re blaming it on me!” She shouted, despite all the evidence to the contrary.

    “I think I could tell when I wet myself.” Justine replied, poking at her padding through her onesie and finding no sign of a squish or warmth. “You, on the other hand…” Reaching towards her twin, she prodded the padding she wore, and could practically feel it even through the onesie. “Well, you apparently need these diapers.”

      Caroline continued to blush, and glared at Justine with all the intimidation she could muster. “O-Oh, yeah? Well, if you’re gonna keep teasing me about this…” She said before jumping towards Justine. “Then maybe you should know what this feels like!” She shouted, before a bright light enveloped the two once more. 

       Once again, with a flash and a flock of ethereal butterflies, Lavenza stood there once more, wearing her infantile dress that clearly exposed her now wet diaper for the world to see. “Ah, I see that my two halves caused a bit of trouble while they were out…” She muttered as she looked down at her padding.

    Once again everyone was left in shock, and it only confirmed that what they saw before was not a trick of the eyes. However, though still utterly shocked, Kirumi saw a girl in a soaked diaper and knew she had to come to her aid. “Yes, it certainly seems so...now why don't we get you out of that wet thing and into something more dry?” She asked while starting to lift her up.

      Lavenza had the faintest hint of a blush on her face as she was picked up and cooed at like she was an infant, but she nodded regardless. “I would certainly appreciate that… Thank you for your assistance.”

    “You're welcome...it's what I'm here for, after all.” Kirumi said as she brought the girl over towards a changing table and laid her down, reaching towards the tapes of her diaper and tearing them away, before lifting her legs and beginning to wipe.

      The feeling of the cold wipes on her skin admittedly caused Lavenza to shiver a little bit, but she didn’t move much outside of that, since she didn’t want to make this job any harder on Kirumi than it needed to be. “Once again, I appreciate your help…” She said with a small blush still on her face.

    “Trust me, I've changed plenty of diapers while here. This is nothing much...and in fact, you're more well behaved than plenty of them…” Kirumi muttered as she proceeded to powder and grab a new diaper, identical to the one Lavenza had on before, and promptly taped it on.

      As soon as she was taped into a new diaper, Lavenza hopped off of the changing table, smiling at Kirumi before going back to playing for what little time she had left in the club for today. “I must say, this club has been far more fun than I expected. I will certainly spend every day I can here.”

    “Really? That's good to hear. We’re happy to have someone like you.” Kaede said, even if she was weirded out by a few things this girl did and said. Mainly the splitting into two. Yeah, that would need to be the most concerning thing. “Just remember, as I said. Don't tell anyone.”

      “Of course, I won’t tell a soul. This club shall stay secret.” Lavenza said. While she still didn’t really understand why Kaede wanted to keep this club so private, she wasn’t about to go against the rules she was being told. “You needn’t worry.”

    “Good...then continue playing for now, and when you're ready to go, you can get dressed back as normal and head out.” Kaede explained, before quickly adding on. “And feel free to keep the dress if you'd like...and take a few diapers with you. Plenty of the girls here do.”

      Deciding that now was as good a time as any to leave and prepare for the next day of school, Lavenza nodded as she stood up and began to walk off towards the changing room. “I shall do just that. Thank you for your kindness, Kaede.” She said as she headed into the adjacent room.

         It didn’t take long for Lavenza to come back out, wearing her usual Velvet Room outfit, along with a backpack that seemed a lot more full than it was when Lavenza first showed up. Giving a respectful curtsy to the rest of the club, Lavenza smiled. “Thank you all for welcoming me as a member of this club. I look forward to our next meeting.”

    Many of the girls waved to their new club member as she prepared to leave, telling her to enjoy the rest of her day and come back any time, before resuming what they had been doing before. She was certainly a strange new club member, but plenty of them were strange in their own ways too…

      Lavenza began her walk away from the school and towards her home as soon as she was waved off by the rest of the club. Of course, that walk didn’t take long at all, as soon enough a door that only she could see appeared in front of her, and she walked into it without hesitation. To anyone looking, it would seem as if she had just disappeared into thin air, but in reality she had stepped into the Velvet Room once more.

      Waiting for her there was Elizabeth and Margaret, both eager to hear about how her first day at school had been, like excited parents who were waiting for their daughter to get home. Lavenza simply smiled, before tossing her bag over her shoulder and beginning to unzip it.

      “My first day at school was quite an eventful one, sisters. And I have many interesting things I obtained from said day to show you.” Lavenza said, fully unzipping her bag and pulling out the contents of it. Namely, a thick blue diaper and the infantile dress she had worn today.

        “Allow me to tell you the story of the club I decided to join…”
