College life is normally difficult, but compared to saving the world with SEES twice and rescuing her best friend it was a breeze for Yukari Takeba. The enjoyable aspects of her college life, the freedom to go and do what she wanted, the interesting subjects covered in classes that she got to pick and no longer having to traverse hellish mazes battling shadows to save the world made her smile on a daily basis. Her problems in life had actually lessened since graduating from Gekkoukan High School.

Truly it was a different world, one that marked a new chapter in her life. There was only one especially pesky problem that had followed from her high school days and she loathed it. Now, as she paced back and forth in her room staring at the laminated chart covered in various numbers, it haunted her.

“I wish this wasn’t put up here…” she sighed, looking at all the red negatives as opposed to the very few green positives.

In an erasable space at the top the month was neatly written while underneath were the words that plagued the college student: Yukari’s Potty Chart.

The continuous use of her persona while fighting her way through Tartarus proved to be too much stress for her body. A little after Minato joined the Specialized Extracurricular Execution Squad she started having... issues. It wasn’t a common problem from what she could tell. None of the other SEES members developed it whilst using their personas, but over time Yukari grew increasingly incontinent through repeated trips during the dark hour.

It started with a humiliating accident as she and the group left the winding tower one evening. A steady stream of humiliating wetness snaking down her stockings and dripping from her panties, she was glad to be at the back of the group when it happened because she was able to hide it better.

Because of her position the only person who had noticed was Mitsuru Kirijo, who lept into action and spirited Yukari away from the others. Initially having written it off as a fluke after reassuring the upperclassman instructed Yukari to come to see her if it happened again. When the incidents began repeating more and more did they determine Tartarus to be the cause and the 3rd year offered an unorthodox solution.

Within a month of her initial accident, Yukari was wearing pull-ups built for a grown adult, courtesy of the Kirijo Foundation’s R&D department. When the accidents worsened she was demoted down to diapers.

As the problem became more and more consistent Mitsuru-senpai instituted a leveling system. Something to track Yukari's accidents and incentivize wearing panties again. The only way to raise her level was to use the bathroom normally, and she needed to tell her senpai about it almost immediately afterward.

Because her time in Tartarus didn’t lessen, neither did her time in diapers. Mitsuru’s system was extremely harsh; the only way to lower her “diaper level” was point by point while any accidents raised the level higher by multiples. By the time the entire SEES Crew had defeated Erebus and freed Minato from his duty as the great seal holding back Nyx, Yukari had fallen to the lowest end of the diaper level scale. This meant having to constantly wear a massive diaper with 2 stuffers in it.

Luckily, after graduation much of the SEES team ended up being accepted to the same college, making it easier for the responsible redhead to keep track of her “student.” Yukari herself hated the system, thinking the odds were unfairly stacked against her as it felt almost impossible to break out of diapers after the first time in them. Even getting the double diaper off to use the restroom was a difficult task and left Yukari piddling her pants more than once while staring at a porcelain bastion of relief.

Several months into her first year of college and lots of difficult potty re-training, she’d finally risen her diaper level to a respectable level twenty-nine. This meant that she got to wear pull-ups during the day and diapers during the nighttime. It wasn't ideal but it was better than being fully diapered 24/7.

"5:58." she noted pacing the room while waiting for Mitsuru. At 6:00 o’clock every night was when she’d come in to change Yukari and this time Yukari was ready for her. She was proud to claim that she’d kept her pull-ups dry all day and had a positive point for Mitsuru to chart when she arrived.

Still, 6:00 o'clock was her own personal “dark hour” and she found it hard to remain upbeat this time of night. “I can’t even fight it at this point,” she mused, “not unless I want to endure one of Senpai’s punishments…” Yukari thought about how her caretaker hadn’t started out as ruthless as she was now, but she was so insistent that the brunette adhere to her system. After multiple attempts to sneak back into panties or escape the system all together she turned to humiliating punishment, each growing more and more brutal than the last.

The promise between them was that if Yukari could maintain a month at diaper level 0, panties, she could be free of Mitsuru’s system.

The clock by Yukari’s bedside hit 6:00 o’clock and on cue, the door of her dorm creaked open slowly. Mitsuru never did knock as the concept of privacy between the two of them was completely lost, instead striding in confidently. Behind her a figure with headphones hanging from his lapels stood quietly in the doorway, blue hair sweeping over one eye.

“Mi-Minato!?” Yukari exclaimed, surprised to see her former teammate following her caretaker in. She turned to Mitsuru who was eyeing her with her usual calm, emotionless gaze. “What’s going on Senpai, Do you think you can just bring other people in here like that!?” she asked indignantly, feeling her emotions well up, “Why is Minato here? Don’t we have to do the thing?”

Yukari crossed the room, strategically placing herself in front of the potty chart displayed so prevalently on her wall. She hoped her attempts at being secretive with her problem hadn't been for nothing. Her long-running infatuation with Minato had forced her into putting extra effort into hiding her “problem” from him in the past.

Mitsuru’s earth-toned eyes focused on Yukari, specifically her skirt. The brunette noticed this and stepped back towards the wall, trying to keep the distance from her. “This is a solution,” Mitsuru said coldly, approaching her schoolmate while she remained backed into a corner, “I’m feeling rather overwhelmed attempting to keep up with my college work while taking care of you.”

Yukari was somewhat surprised to hear this as her friend had never mentioned it before and seemed rather uncharacteristic of her. She'd considered in the past that Mitsuru maybe even enjoyed toying with her, so she wasn't sure what'd suddenly changed. When she thought about it, panic hit her. “Wait, what’s a solution?” she asked tentatively, still on her guard.

“I’ve decided that Arisato-kun will be in charge of your issue from now on.” Mitsuru said matter of factly, “I’ve already let him know about your problem and the history of it so we can have a smooth transition, now please allow me to check your pull-up so he can see how the system works.”

“Not happening!” Yukari yelled, stomping her foot on the ground, “Stay back Senpai, I won’t let you do this!”

Mitsuru just sighed and continued closing the space between Yukari and her. “You seem to think you have a choice in this–do you remember what happened last time you told me no?”

Yukari shuddered, she did in fact remember what happened last time as the soreness in her rear seemingly took forever to wear off after senpai’s brutal bare-bottom spanking.

“Mitsuru-senpai, you can’t just bring in someone else to deal with me.” Yukari said with anger flowing through her, “I trusted you and you’re just going to pass me off to someone else? To tell them my secret?”

As her outward anger flared a feeling of warmth spread between her legs. Her pull-up swelling with an uncontrollable accident brought on by hightened emotions. Yukari whimpered, feeling Mitsuru’s hand lift her skirt at the perfect time to watch the simple pink training underwear stain and sag between her legs. Without words Mitsuru dropped Yukari’s skirt and guided her away from the potty chart on the wall, marking today with a minus 3 and tallying her score.

“You have descended back down to level thirty-one.” the redhead said, motioning Minato in from the doorway. This whole time the stoic student said nothing, instead choosing to watch the scene unfold. He responded to Mitsuru’s beckoning, closing the door behind him as he entered.

While the redhead began explaining the chart to Minato, Yukari stood stammering. “I-I can’t believe he saw…” she said, stunned. She turned her attention to the pair going over the chart and stamped her foot again. Her emotions were now a runaway train, and she couldn’t contain her anger towards her senpai despite the threat of punishment.

“Stop talking about me like I’m not here!” she shouted, “I don’t need diapers, she can’t make you put me in diapers either Minato-kun. Don’t you see how insane this is? I’m not a baby and neither of you can treat me like one!"

Misato stood quiet, locking his unblinking, unemotional blue eyes with Yukari’s for a moment before cracking a slight smirk. “What you just did here shows otherwise.”

Even with so few words Yukari was shocked. “Is he enjoying this?” she wondered, making for the door to her dorm. She didn’t have to stand there and listen to this.

However, a stern word from Mitsuru stopped her in her tracks. “I don’t think so.” she said coldly, “Talking back like that and then trying to run? That definitely earns you a punishment for tonight.”

Yukari huffed and turned on her heel, facing the pair once more. Mitsuru was already at the bottom drawer of Yukari’s dresser, pulling sinister things from it while Minato watched the brunette’s angry display. Normally she wouldn’t be so outwardly aggressive, especially towards Mitsuru, but the whole situation bothered her; she didn’t want to be diapered again, not after fighting to work her way out of them like she had. Minato’s presence made it all the worse too–an extra layer of humiliation.

The redhead returned with a length of rope in her hand and something red and rubber in the other. “Strip.” she said, giving a simple command with more authority than either of the other two had ever felt before.

Yukari shot her an angry look and an exasperated sigh. “I will not, not while he’s here.” Yukari said, crossing her arms and standing her ground.

Mitsuru shook her head and waggled a finger at Yukari’s defiance. “This can still become more severe for you.” she said flatly.

Yukari’s eyes went momentarily wide, and the realization that Mitsuru likely wouldn’t hold back frightened her a bit. She slowly started to peel away her clothing, giving off various sighs and huffs with each piece.

Even Minato was surprised by this and turned away to afford his diapered friend some modesty. “I wouldn’t bother,” Mitsuru said, “you’ll see it all soon enough.” Still, the normally quiet young man was hesitant to turn around, letting Yukari know that there was still decency left in him.

Yukari dropped her skirt and uneasily removed her top, unhappy to be exposing herself to the room. Even as a college student who was of age it felt weird, especially with the sagging pull-up between her legs.

With expert movements, Mitsuru tied the rope around Yukari’s wrists and cinched it tight, leaving a long section trailing out like a leash. She worried for a moment that senpai would take her and parade her around just like she had in front of Minato. Luckily she wasn’t due for that much misfortune. Instead, the extra rope was fed through a metal ring attached to her dorm’s ceiling and tied off to her bedpost, leaving Yukari standing in one spot with her trapped wrists slightly raised toward the ceiling.

“When did she install that?” Yukari wondered. It was only the latest addition to her room: often when she left for classes she’d return to see a new component added to her room such as a bench for spanking or a new stash of diapers waiting to replace the ones that she’d run out of earlier.

Yukari stood waiting in just her pull-up as Mitsuru pulled a red rubber bag from behind her back, within which must have been liters of water sloshing around inside. “I think to cement the fact that you are descending back into diapers full time an enema is appropriate.” Mitsuru said, her tone had just a hint of sadism in it.

The redhead hooked her thumbs into the stretchy waistband of Yukari’s pull-up and wiggled it off her hips, allowing the soaked padding to plop to the ground with a heavy squish. “Arisato-kun,” Mitsuru called, causing the room’s other inhabitant to turn around, “Please come take this pull-up and dispose of it in the diaper genie next to the dresser. I will also need a fresh diaper from the cabinet right next to it.”

Minato gave a simple nod at the request and stepped forward, carefully picking up the soggy diaper while deliberately avoiding eye contact with Yukari. He shuffled away without a word, following Senpai’s orders quietly.

Yukari in the meantime was left hanging and waiting. All she could do was sulk at her situation. “Are you at least going to clean me up?” she asked, throwing as much annoyance at Mitsuru as she could.

“What’s the point?” the redhead asked, “You’re about to lose another 3 points to a daytime messing. It’ll give Arisato-kun a good chance to change you afterward.” Without any warning Mitsuru pushed the lubed enema bulb between Yukari’s cheeks, eliciting a loud gasp.

“You could have said something.” Yukari murmured, shifting uncomfortably.

From behind Mitsuru scoffed, “Fine–here comes the water next.”

The cold flow of water made Yukari feel instantly uncomfortable as it filled her insides. Minato meanwhile returned with the folded thick diaper, handing it over to his senpai while locking his eyes onto Yukari’s squirming form.

“Q-Quit looking dummy…” the brunette said through gritted teeth toward Minato. She wished so much that he wasn’t here to see this and if she had to push him away to make it happen she would.

Minato didn’t waver, paying no heed to her hard looks and cold words. He just shook his head and stepped back, leaving Mitsuru to unfurl the massive plastic-backed diaper in her hands. A small slap to Yukari’s thighs was the only indication she needed to spread them at her caretaker’s command. She felt the plush crotch of the nappy press up against her, bending the rubber tube and encasing Yukari’s waist with a crinkly plastic protective shell.

The redhead worked quickly, her practiced hands taping up the diaper tight without the aid of a changing table. She pulled out the length of the rubber tube that brought water into Yukari's rapidly filling bowels up through the ruffled waistband of the nappy, leaving it in place as she was diapered.

With her work complete Mitsuru stepped towards the door and pointed Minato towards his new charge. “She’ll need a change once the enema bag is emptied, just remove the bulb once it’s done and make sure she’s fully emptied or else you’ll have a bigger mess on your hands.

Minato nodded, his face, as usual, not betraying any emotion about the situation. “I will.” he said.

Mitsuru turned to leave, tossing a comment over her shoulder as she walked out, “And make sure you mark this as a daytime accident. It reinforces her shameful dependence.” The door shut behind the redhead, leaving the other two alone.

Minato’s eyes locked with Yukari’s and he shook his head. “I’m not going to do that.”

“Why not?” she asked, wincing at the fullness and pressure building in her lower abdomen, “It’s what Senpai told you to do.”

The student just shrugged, crossing the room to check the rapidly deflating enema bag. “Hardly seems fair.” he said, “Looks like it’s about empty, just a few more seconds.”

Yukari grimaced, feeling the churning liquid irritating her intestines as they were filled. While it had just been a two-liter enema bag the amount of liquid causing her tummy to bulge out felt like much more. She’d never been so stuffed in her life.

Once the flow into Yukari stopped she let out a sigh of relief, glad that at least the worst was over. That was until she remembered what came next, especially when Minato’s hand worked its way past the waistband of her padding and popped out the bulb of the enema tube.

She had only seconds until the flow forced its way back out of her and into her padding. “I-I can handle this if you just untie me.” She groaned, her belly gurgling loudly, “I don’t need you or these stupid diapers.”

Minato stood off to the side nodding at her statement. “We’ll get you to that point eventually,” he said quietly.

Unsure how to respond, Yukari let out a soft groan as her body’s first push bulged out the back of her crinkly nappy. She grimaced, unable to make eye contact with Minato as lurid sounds filled the room and her nappy dipped lower and lower.

Had Yukari been able to look up despite her embarrassment she might have been able to see a genuine enjoyment of the situation in the normally emotionless Minato’s eyes. He jumped at any chance to see Yukari more as she had been influential in his release as the seal holding back Nyx, not to mention sealing the entity against Erebus to replace him.

Their time in SEES together left him with great respect for the brunette along with a slight crush that only grew as they spent more and more time together. Now in college, he felt like they barely saw each other. Yukari was constantly busy with her acting classes and archery club whenever he had time.

When Mitsuru approached him with her offer to take care of the brunette’s embarrassing secret he was initially shocked. Not only was he completely unaware of his teammate’s problem, but he was also surprised with how little it mattered to him. His opinion of Yukari didn’t decline because of her diapered state, rather, he felt a strong urge to take care of her. He even wanted to see her diapered once he knew. With a newly acquired special interest in Yukari’s diapered exploits, he agreed to help Mitsuru in taking care of her.

Once she finished expelling the massive enema, Minato stepped forward and rubbed her back gently, feeling a slight sweat from exertion creating a slight film on her bare skin. “Ready for a change?” he asked gently.

Yukari looked up at him with a sour look on her face, “Just untie me and I’ll do it myself.” she said, the humiliation of the situation leaving her with a venomous tone.

Minato didn’t falter, freeing her wrists from the rope and leading her by the hand toward a changing mat. “Senpai wouldn’t like that would she?” he said. Yukari’s attitude didn't affect him. Instead, he met her with a tender smile that softened her.

She submitted to her change and bedtime easily under the calm control of her new caretaker. She still blushed and squirmed but her huffy attitude quieted down, making it easier for Minato to enforce Mitsuru’s system.

When the blue-haired boy left the dorm, flicking off the light and closing the door, Yukari almost mentioned that he’d forgotten to mark her negative points from messing her diaper. She quickly realized this was intentional as per his previous comment about it being ‘unfair.’ The brunette nestled under her covers, feeling the bulky plastic of her diapers rustle as they dragged against her sheets.

Underneath the covers, she blushed, feeling the creeping emotions of infatuation again. While they’d jumped several steps due to her exposure Yukari felt like she’d also grown closer to Minato. His care showed a soft side he didn’t display to the rest of the world, one she hadn’t seen since their hug in her dorm room in high school.

Yukari kept up her general resistance to diapering over the next month, fighting back and squirming against Minato whenever the time came for a change. It made it all the harder that she almost outright refused to go to him for a change in the beginning. As a method of rebellion, she sat through many classes and meals in soiled pampers, preferring to get a rash as opposed to involving her crush.

When Minato caught on to this he counteracted by tracking Yukari down and checking her regularly. She almost shrieked the first time he strode up, took his hand out of his pocket, and pulled the back of her skirt and diaper’s waistbands to see if she’d had an accident outside of a regular check. When he saw that she had, he was quick to take her hand, an action that caused her heart to quicken, and pull her into a nearby bathroom.

The normally silent student was more prepared than she knew with a backpack full of changing supplies and faith that the changing table would hold her weight.

“Hop on.” he said.

“You can’t be serious…” Yukari said skeptically.

“I am, do you want me to lift you?” He asked, positioning his arms to cradle her form.

”You don’t think I’m going to let you lift me, do you?” she scoffed.

“I’m sure you’re not that heavy.” he said with a slight smile.

Yukari bristled at this, whether the joke was unintentional or not. “Don’t make jokes about a woman’s weight!” she said, climbing onto the table herself, “I’m not too heavy.” Even with all her bluster, she wasn’t sure that she believed her own declaration.

Luckily the table held and Minato was able to change her privately and without any hassle. She caught the whispers of a few other students who saw them leaving the bathroom together and blushed but resigned herself to not letting it bother her. After all, they didn’t know the full extent of the situation.

As they walked Minato pulled out a small notebook. Yukari saw out of the corner of her eye that she was marking her score on a miniaturized version of her potty chart, making sure to put it on the big one later.

“You know,” he said hesitantly, his eyes locked on the copy of her chart, “If you’re not careful you’ll be down to the lowest level on Senpai’s scale.”

“I know.” Yukari said, remembering that brief time she was actually rising on the chart rather than gaining negatives because of her stubbornness.

“If you want,” he started, turning to focus more on Yukari and drawing her gaze into her own, “I can help you. I’m not going to punish you like Senpai. She wants progress reports, but if you’re getting better she won’t get involved.”

Yukari felt herself blush a little, struck by the earnest nature of Minato’s offer. “Y-Yeah!” she said enthusiastically.

From that point on the two spent most of their time together, only separating when they had classes and clubs. Even then Yukari’s caretaker regularly texted her to see if she needed, as he put it, ‘the potty’. To her surprise, the constant reminders and positive reinforcement afterward actually helped a great deal.

Other than that they ate, studied, and relaxed together the rest of the time, with Minato providing consistent diaper checks to his charge while they were together.

Yukari’s reluctance to allow this was severe at first, but eventually she softened to it, not even realizing until after when one of his fingers slipped past a leak guard to check her nappy at a certain point. He was never as harsh as Mitsuru when it came to discovering her wet or on a close call. The redhead’s system called for Yukari to take a negative point whenever she wet due to just barely not making it to the bathroom. Minato however, never counted these against her, citing that at least an effort was made on her part.

With Minato’s help, Yukari brought her ‘diaper level’ all the way up from a paltry thirty-eight to a respectable eight, meaning she’d gone from thick diapers 24/7 to simple pull-up during the night and her regular panties during the day.

Now, a full month later Yukari sat in class, enjoying the lack of bulky padding between her thighs. As she half-listened to the professor at the front of the class lecturing, she thought about her time with Minato and how much she wanted to see him again after this course.

They’d grown increasingly close in this time, even having the subject matter between the two of them having drifted more towards shared interests and things they could do together. Minato attended one of her archery meets and during lunch one day she found herself listening intently to him explaining his time in an online game despite having no interest in it previously.

She felt something come over her while she sat there half-listening to her professor. It was a brief sadness because, despite the nature of their time together, Yukari actually enjoyed hanging out with Minato even if he spent some of it checking her diaper. Maybe that made it a little better even, brought them closer. She tried to shake that thought out of her head quickly, but a dawning realization that it may soon end hit her like a Megidola.

She didn’t want their relationship to end like that, even if it meant being diapered while she was with him. A buzzing from her bag signified a text message, one that she’d somewhat expected. It was Minato, making sure she didn’t need to use the bathroom at that moment. Yukari wasn’t sure how he did it, but he almost always was right on time with her needs. A slight pressure in her bladder was nagging at her.

There was plenty of time to make it to the bathroom, and Yukari briefly considered all the hard work it’d taken to get here after how long she’d spent in diapers under Mitsuru’s care. None of that mattered more to her at that moment than her time with Minato though, and in a rash and impulsive move she gave a slight push with her bladder muscles.

Warmth spread through the thin fabric of her pink underwear, quickly seeping through due to their lack of absorbency and pooling on the plastic chair beneath her. The heated liquid built up quickly, soaking her bottom and the back of her skirt as it spread with the increased flow. The basin of the chair filled within seconds, Yukari’s flimsy clothes failing to soak up the accident. A steady stream of the acrid liquid began overflowing down towards the floor, making a steady *plip* *plip* *plip* sound that filled the space around the brunette.

She regretted her decision almost immediately, realizing that the aftermath wouldn’t just be seen and handled by Minato or Mitsuru. This was a mess she’d have to deal with and there wasn’t even a way out of this classroom without somebody spotting the puddle forming underneath her.

From behind Yukari, sitting about two rows back, Fuuka Yamagishi sat up in her chair. Her ears perked to the faint sound of dripping and she looked around quizzically. When her eyes hit the back of Yukari’s shuddering form she immediately gathered what was happening, especially upon noticing the steadily growing puddle under her friend’s chair.

Without thinking the shy girl sprung into action, grabbing Yukari’s hand and tugging her up from her seat. “W-We should go.” Fuuka said quietly.

“I-I-I c-can’t...“ Yukari said, frozen, skipping like a broken record. Her friend pulling her to her feet hadn’t done her any favors either, several students most likely noticing the massive wet spot on the back of her skirt and the dripping liquid from the fringes serving as an even more tell-tale sign of her accident.

With hushed whispers from other college students all around them who’d noticed both the puddle and the scent of urea, Fuuka led Yukari out of the room by gently tugging on the stunned girl’s hand.

Once removed from the situation Yukari recovered from her stunned state, giving a thankful look to Fuuka for her help. “I can’t believe I did that,” she said in between calming breaths, “thanks for getting me out of there.”

Fuuka nodded, giving a kind smile to her sniffling friend, but didn’t let go of her hand. She pulled at Yukari, trying to lead her away from the classroom door.

“Fuuka, what are you doing?” the brunette asked, “I’ve gotta go find Minato for—reasons…” She needed a change and going to Minato was how she'd accomplish that, but she didn't want to let her shy friend know that.

Fuuka kept her hand in a tight grip and was still pulling Yukari away from the class. “I-I know where Minato is, I c-can take you.” the blue-haired girl stammered, she wasn’t sure how convincing her lie was but she needed to get Yukari away. She had a specific destination in mind for her friend.

Lucky for her Yukari followed without question, whether it was because she was still frazzled from her accident or didn’t think her very sweet friend could have ulterior motives was unknown to Fuuka.

When the end of the trail led to the library though, the brunette seemed a little confused as to why they’d ended up here. “I thought we were going to see Minato,” Yukari said, her concern slightly growing.

“N-No.” Fuuka said, pointing at the sliding door into the room, “Senpai is in there, I-I’m bringing you to her.”

Yukari now understood her friend’s outward nervousness and why she’d been stuttering this whole time–she was taking her to her other caretaker. “She knows!” Yukari realized, “She not only recognized my accident in class but also knew to go to Mitsuru-senpai about it.”

Before Yukari could make her objections heard Fuuka was pulling her through the door and toward the table Mitsuru-senpai occupied. Once inside the library, the brunette kept quiet, knowing that disturbing everyone would only pull attention towards her soaked skirt.

Upon hearing the pair’s footsteps Mitsuru looked up from her book to see Yukari in her pee-stained outfit and Fuuka proudly leading her. The shy girl quietly explained the situation while the brunette waited patiently, knowing leaving would only extend her punishment. Once Fuuka finished her explanation she turned to leave, earning a soft “Thank you.” from Mitsuru. She turned and left and as she shuffled out Yukari could swear she caught a slight crinkle from around her waist as she walked.

Back in the Library, Mitsuru packed up her books and took Yukari’s hand, leading her along just as Fuuka had done. “I’m disappointed,” she said, taking her charge back to the dorm rooms, “From what Arisato-kun was telling me you were actually making progress toward your potty training. To know that you’ve slid back down with such an embarrassing daytime accident…”

Yukari tried to stammer back in defense, but no words left her mouth–she didn’t even have a good excuse for Mitsuru. Her wetting her panties like that had been entirely intentional, and deep down she was sure she deserved the punishment. “I hope this doesn’t mean that senpai is going to take over again. I-I want Minato to take care of me…”

It was the first time she’d admitted to herself that she desired her crush’s care like that. To her it showed that she didn’t just have a simple crush: while he’d spent his time caring for her, Yukari was apparently falling in love with Minato.

Once inside the dorm, Mitsuru began removing Yukari’s clothes, prepping her for the next punishment. Her soiled clothes were tossed aside and the brunette was instructed to lay down on the changing mat while the redhead gathered supplies.

A quick wipedown ensured that Yukari was completely clean before shoving a new and very thick plastic diaper under her. Two puffy stuffers rose upward when compressed by the brunette’s bottom. “Hey!” she complained, “I only went down to level eleven. I shouldn’t have to be diapered with stuffers during the daytime!”

“That’s it.” Mitsuru said with a huff, opening the small fridge by Yukari’s bed and grabbing something from inside. In a flash, the brunette felt something cool pass between her lips only for an extremely cold and sour bulb to rest on her tongue. “I’m tired of all your complaining, so maybe that sour soother will teach you a lesson. When all the ice mixed with lemon juice is gone it’ll fall out and then we will see how much you talk back.”

Yukari fumed behind her pacifier but said nothing, sucking on the sour-tasting ice and hoping it would diminish faster because of it. While she suckled babyishly, Mitsuru taped up the new diaper, pressing the stuffers inside tight against Yukari. The plastic shell felt excessively full with the mound of fluff and she hardly believed it had room for any accidents she might have.

Next came the rustling plastic pants with a tinkling chain hanging from the back. Mitsuru slipped this over Yukari’s legs and diaper with ease, cinching the chain tight around her waist and locking it with a small *click*. “Now we just need an outfit for the trip.” Mitsuru mused.

“Trip?” Yukari wondered while sitting up. It took a little effort given the bulk of the padding and she ended up falling back once or twice because of how compact the cushion around her bottom was. When she finally got up and saw what Mitsuru had pulled from her closet she shook her head vigorously only to be met with a slightly sadistic nod from the redhead.

Before she knew it Yukari was traveling across campus with her senpai leading her by the hand wearing her old high school uniform. The black pleated skirt was far too short to cover the bulging diaper crotch contained within her bright pink plastic pants. She tried to pull down the hem of her skirt and hide the padding from various students walking by to no avail as tugging one way lifted it up on the opposite end and more than once she exposed the waistband of her diaper by tugging a little too hard.

Fiddling with her skirt couldn’t hide the bright bink pacifier in her mouth and despite her protests, Mitsuru had insisted she keep it in. She suckled at the sour bulb and grimaced. Part of her had expected to get used to the harsh flavor of the frozen juice, but she never did and it effectively made Yukari wish she hadn’t been so quick to talk back to her caretaker.

The walk took them off-campus and to a small apartment complex a few blocks away. Yukari was confused as she recognized this place, though only in passing. It was the building Minato lived in. While glad to see that the building was seemingly deserted and that she might get to see her kinder caretaker, Yukari felt a nervousness creep over her. When she caught the sight of someone with short silver hair walking down the hallway towards her and Mitsuru it only grew worse.

“Akihiko!” Mitsuru called, waving down her fellow upperclassman and motioning him over.

He waved back, drawing closer to them, his casualwear slightly damp, indicating he was working hard on something, enough to make him sweat anyway.

Yukari in the meantime cringed upon seeing him, trying to turn away and hide despite Mitsuru’s grip holding her firmly in place.

“Is it all done?” the redhead asked, indicating down the hall where he’d walked from.

“Yeah it’s done,” he replied, wiping away some sweat from his forehead. “That was a lot of work for just him to do. You should have called me in sooner.”

Mitsuru turned to Yukari whose gaze was firmly planted on the floor. “I didn’t think we’d need it sooner…”

The brunette couldn’t believe it, Akihiko didn’t even acknowledge her diapered state to her or Mitsuru meaning he likely knew already. “Did Senpai tell the whole team!?” she wondered, feeling even more flustered than before.

“Well,” Akihiko said, walking past the pair, “It should be perfect for her.”

The pair continued down the hall where a cracked apartment door waited. Mitsuru didn’t bother knocking, pushing her and Yukari’s way inside. In the middle of the apartment stood Minato in a t-shirt, similarly sweaty like Akihiko was. All around his room interspersed with his own simple furniture was an assortment of gigantic baby furniture. A crib, changing table, and high chair were all scattered around the space, looking shiny and new in comparison.

At that moment Yukari’s pacifier slipped from her mouth, the last bits of frozen lemon juice having melted away and coated tongue. “Wha’s this?” she asked, surprised to hear that her numb tongue couldn’t quite form letters correctly.

“This is your new home if you continue down this path.” Mitsuru said seriously, gesturing to the room. “Obviously you cannot be trusted as a college student if you continue to wet your pants so shamelessly. I’ve decided that if you slip back down to level 45 again I’ll take you out of classes and you’ll live here from now on. Originally I was going to set you and I up in an apartment like this, but Minato has volunteered to be your full-time caretaker if that happens.”

Yukari couldn’t believe what she was hearing, it all sounded insane to her that all agency would be removed from her like that if she failed Senpai's system. However, she wasn’t necessarily opposed to the idea upon hearing that she and Minato would be the ones living together. Something about letting her former team leader care for her as opposed to Mitsuru didn’t sound as bad.

“For tonight,” Mitsuru continued, “you’ll stay here, just to give you a taste of what this life would be like if you keep doing this. Those locking plastic pants will stay on until tomorrow, so it’d be best to hold back as much as you can unless you want to be sitting in a very soggy diaper by the morning.”

Outwardly Yukari huffed at the concept, stomping her foot which elicited a loud crinkle from her bulky padding, but inwardly she smiled. It wouldn’t take long for her to break the training she built up with him and with a slight push, she let a small stream into her padding to bring her one step closer to living with her new “daddy”.

She locked eyes with Minato as the flow left her body, splashing against her pure white stuffers and soaking them. His blue eyes showed an understanding that not even Yukari could explain. Part of her screamed that her actions were rash and impulsive, that she should stop. Another part of her made it seem like she should keep going–that in the end, it was the right path. No matter what she decided later she'd already taken the first steps toward babyhood under Minato and something about it felt right.
