Mina Ashido was nervous as hell as she waddled through U.A. School's halls, trying not to meet anyone's eyes as she hurried to her classroom, class 1-A. She didn't want to see the looks of disgust or amusement on other people's faces.
You see, usually Mina would be quite the athletic and sport girl, with a lightly toned stomach, healthy thighs, good muscles and despite her pink skin, dark eyes and horns which might be off-putting to some, she was still quite the snack to look at usually if she did say so herself.
Key word being usually. Because usually she wasn't up earlier than normal for class, usually she wasn't on her way back to U.A. from her parents house due to helping them move into a new home the night before. Usually, she wouldn't have been hit by a villain's quirk misfiring that…
That made it so she had to put up with the effects of all the food she would eat and had eaten over the past and future 30 days all at once, resulting in her turning into what could only be described as one thing.
Fat. She had become fat. Her breasts had become like sagging beach balls in size, her thighs were as thick as tree trunks, yet had none of the solidness, instead being as about as firm as jello. Her neck had expanded enough that she swore it could be classified as a second chin, and her cheeks had begun to droop. Her arms, while not as thick as her thighs, had also grown as thick as street lamps and she swore she could feel extra flab flapping under her armpits, slapping against her.
And her stomach… Her once toned flat stomach had expanded enough that several of her outfits' lower buttons had popped off, her belly button on full display as her stomach wobbled and bounced with every little step, now at a size that could make one be forgiven for assuming the U.A. student might have swallowed a mini cooper.
Mina… would have usually brushed it off to be honest. Sure some people would of been jerks about it, but Mina didn't care what most people thought of her looks. Most people. There were two however she cared deeply about that and had her nerves on fire.
Green haired, freckle faced cutie and hunk Izuku Midoriya, and hot, sharp-witted purple haired Kyoka Jirou, her classmates in 1-A and Mina's long time crushes since her second month at U.A.
She had been trying to ask the two out for months, with increasingly frustrating results (no it wasn't her fault she never came out and asked outright and instead resorted to things like trying to convince them to do things like wear matching Halloween costumes with her to a party so she could call them dates after the fact, shut up), yet she was certain they liked her back. She'd certainly caught them staring enough times.
But Izuku was quite the fitness nut, up from five in the morning to do his runs, going out for another run after dinner and working out in the gym for hours some days, and Kyoka? She never failed to speak her mind in most cases, and if she didn't like something, she'd definitely make it known.
And Kyoka had always been sensitive about her small size so…
She gulped as she looked at the 1-A door. Everyone else she could ignore, but she still avoided their gazes because if Izuku and Kyoka were disgusted, which it felt distinctly possible they might be, that would hurt enough without the build up of others staring at her.
'...Might as well get this over with…'
And so she opened the door, only to be greeted with what she thought would be the worst case scenario. Kyoka and Izuku alone, the latter helping the former with some song. Not even Iida, the usually incredibly punctual class president was in yet, leaving Mina faced with only the two people she was most nervous to see.
"Mina?!" Kyoka went wide eyed, and Izuku turned, the freckled teen's jaw dropping at the sight of her.
'Oh god here it comes-'
Their eyes suddenly seemed to sparkle as they both rushed up to her, taking her in with wide excited eyes.
"Did you get hit by a quirk?" Izuku asked, yet his tone, while it held concern also held… awe?
"Or is this a new look? Because it. Is. Amazing." Kyoka muttered with similar awe, unconsciously poking the pink girl's massive stomach and seemingly drooling. "You look…"
"R-Really cute?" Izuku supplied and Kyoka nodded with a blush.
"I was gonna go with hot but… Yeah." The purple hair girl nodded, twirling one of her elongated earjacks, a mutation her quirk gave her. It was an adorable nervous tic.
"E-Either way it's amazing…" Izuku muttered in delight, seemingly distracted by the pink stomach and smiling dopily to himself as it jiggled when Mina began twisting to look between the two of them in shock.
She was shocked and confused, having expected either similar shock and confusion, or even outright disgust from her two crushed. She hadn't at all expected... well, being fawned over essentially.
Hell, the two seemed almost... drunk with pleasure over her size as she stared at them, with their blushing faces, slightly open mouths and eager eyes.
Did they… Were they into bigger girls? Was that the answer? It wasn't anything she'd considered before in regards to what they may have liked when trying to seduce them but... well, if that was the case... maybe this wouldn't be so bad after all?
Maybe… Maybe she could even use this!
"You... really like my size?" She asked, testing to see how they felt before she went full speed ahead with her new, half-baked plan. Izuku looked up at her with a genuine smile that made her heart skip a beat, and made her confident in this new attempt at seducing her crushes.. "You're g-gorgeous like this, right Kyoka?"
Kyouka nodded excitedly, almost seeming dazed as she took in the large and tubby pink skinned visage that was Ashido, wobbling around as she turned to look at the purple haired girl. "A fucking Goddess !"
Mina went wide eyed, her jaw dropping slightly and colliding with her new double chin at the pure and utter joy that had come from the smaller girl when she said it.
"A goddess?" She muttered quietly, stunned at such a visceral reaction from her skinny girl crush.
"The only thing that could be better is if you got even bigger!" Izuku smiled shyly, finally starting to realize how… instinctively he'd reacted to her size, finding his shyness catching up with him, yet Mina's positive response kept him from losing the wind in his sails.
Kyouka nodded again, her own excitement even more pronounced than Izuku's, her eyes practically sparkling. "Yeah! You'd be even hotter with more size, not that you aren't already amazing like this!"
"..." Mina blinked, then smiled down at them, began to bounce and made the room shake slightly as her massive thighs slapped against her enlarged butt. "Then you know what? I'm going to try and become the fattest woman in the world!"
Izuku and Kyouka's eyes widened, before they both seemed to begin absolutely radiating joy as they beamed. "We'll help you!"
Mina giggled, her own eyes sparkling in delight. It was actually working! 'Time to go for the big strike! If I knew this would work I would have been gorging myself on buffets for weeks! Goodbye exercise, hello cute lovers~'
"Good, cause that was my one condition for it. I need a boyfriend and a girlfriend who will bring me all the food and feed me and love me so I don't get discouraged."
They both blushed, but their smiles only grew wider. "We can be your boyfriend and girlfriend. We'll get you whatever you want!"
The exclamation was immediate and excited, as if they were just waiting for this opportunity, and perhaps they were. After all, Mina was certain her size was enticing enough to give them confidence, but she had caught them staring before.
She just had to thank her new life as a fat woman for giving them the courage to actually approach her. She grinned, revelling in the moment of finally being able to say this, even if it wasn't the exact line she had planned in the past for when she got together with them. "Perfect, then come give your big, fat girlfriend smooches~"
And just like had occurred in many, many, many of Ashido's dreams, both of them leaned up as best they could and kissed her each on either of her quivering far jowls, scrambling to get higher to kiss her cheeks properly while their hands pressed against and felt up her soft fat stomach.
That was how 1-A slowly began to become more and more unable to contain the massive pink blob that used to be the fit and sporty Mina Ashido over the next few months... and how Izuku and Kyoka began to need to carry pants to change due to often ejaculating on sight any time they spotted their gorgeous whale of a girlfriend.
Which with her size was eventually nearly 24/7, much to their endless delight. They were well and truly, massively in love. Pun fully intended.
