This is my body?

by TsukiTsundere

Summary:

“H..How are you so hot?”

Katsuki held the waistband of his pants to make sure they didn't fall as he screamed back at Kaminari. “Shut the fuck up Pikachu!”

His voice wasn't nearly as deep as it usually was and it was jarring. Everything about the situation was jarring.

He was a girl.

Kind of.

Somewhat.

Stupid Pikachu bastard.

 

A quirk accident leads to Katsuki changing to have the physical body of a women. Katsuki has..thoughts about it. Why does he feel more at peace than he ever has before? Why does he feel so off about the whole situation? And why is Yaoyorozu staring at him so much now?

Notes:

Transfem Katsuki!

I hope everyone enjoys the first chapter of the new fic!

Stay gay my friends

Chapter 1: My body?

“H..How are you so hot?”

Katsuki held the waistband of his pants to make sure they didn't fall as he screamed back at Kaminari. “Shut the fuck up Pikachu!”

His voice wasn't nearly as deep as it usually was and it was jarring. Everything about the situation was jarring.

He was a girl.

Kind of.

Somewhat.

Katsuki stood in the middle of the common room as most of his classmates stood around him and Aizawa stood next to him. He could see his teacher pinch the bridge of his nose. “Kaminari do not antagonize Bakugou.” He sighed deeply. “As you all can see, Bakugou has been hit with a quirk while he was out on patrol. A young girl panicked when a villain ran through the store she was in and as Bakugou ran through after the villain, she accidentally brushed his arm. He's been checked out and it should only last a week. He's still Bakugou, but physically he has completely changed genders. It's as if he was born a girl at birth. Any questions?”

Katsuki rolled his eyes when Kaminari raised his hand and Aizawa called on him. “Yes, Kaminari?”

Kaminari was staring at him with hearts in his eyes and it made him want to vomit and smack the electric rat bastard. Kaminari was basically drooling. “Why are you so hot?”

Katsuki was about to snarl at him but Kyouka beat him to it and he watched her smack Kaminari in the back of the head. He nodded at her as he heard Aizawa let out an even deeper sigh. “Are there any actual questions?”

The little cretin Mineta raised his hand and spoke. “Can I touch your..ow!”

Katsuki watched as a hardened hand clamped down on the little perverts shoulder and squeezed. He could always count on Eijirou.

Katsuki could see Yaoyorozu raise her hand and his heart did a little leap, but he squashed it back down and looked towards the floor for a second to regain his composure.

Aizawa spoke next to him after a tired sigh. “Yes, Yaoyorozu?”

Katsuki looked up to see Yaoyorozu smiling at him. He had to lock his gaze back on the floor immediately as he felt his cheeks start to flush. “I just wanted to offer that I could make Bakugou some things to wear, at least for this week. He looks to be roughly the same height he was, but his shape is different of course. I..I mean, if he'd like the help of course.”

Aizawa grunted, “That's all up to the golden boy.”

Katsuki rolled his eyes at the stupid nickname his teacher had given him his first year. He was a perfectionist, what of it? He looked up at Yaoyorozu, “That's fine. I..I appreciate it.” (And no he didn't fucking stutter. He just..tripped over his words.)

Yaoyorozu smiled, “I'll bring some things by your dorm later.”

Aizawa nodded out of the corner of his eye. “Any other questions? No? Good. Just go about your business as you usually would. Don't be weird about anything. Kaminari, Mineta. That especially means the two of you. I swear I will expel you both. Now, as you all were.”

Katsuki growled under his breath and Aizawa turned to him. “Come find me if anything happens.”

Katsuki just rolled his eyes, “I'll be fine, dad. I can handle myself.”

This time Aizawa rolled his eyes. “I let that slide once, stop calling me that.”

Katsuki rolled his eyes. “I'll see you and Yamada at dinner this weekend, so no.”

He could see Aizawa roll his eyes this time. “Whatever problem child. Don't forget to remind Hitoshi this time.”

Katsuki huffed as he watched Aizawa walk away, mumbling to himself, “I'm not the troll doll’s keeper.” He'd do it anyway. He then turned back to his classmates and friends who were mainly still watching him. “The fuck are you all looking at? Go away. Actually, do whatever, I'm going to my room.”

He cringed again at his own voice again. It was so light and feminine and it made it really hard to sound intimidating. It didn't sound bad by any means, he..honestly didn't hate it if he was being completely honest with himself. He just didn't want anyone thinking they could push him around now because he would still blow someone's head off in an instant if he needed to.

He made his way up to his room, he knew Eijirou, Mina, and Kyouka would probably be up to check on him in a bit, but he just needed a little bit of peace.

Katsuki changed out of his hero costume that was, as of right now, too big for him. He was going to throw on some boxers, a pair of shorts he could tighten, and a hoodie, but he stopped completely.

He had looked in the mirror.

He had never seen a naked woman before, and he never thought the first one he saw would be himself.

Truth be told, Katsuki had never really given a shit about his appearance. His mom cared more than he did. He took care of himself of course, he wasn't gross and he was in great shape, but he just didn't care for the most part. The only thing he had ever really done was keep himself pretty clean shaven. Body hair and facial hair bugged him.

When it came to his looks though, it had always been what it was. He didn't care how he dressed and he didn't really pay attention to when people called him hot or when people posted about how attractive he was online and shit. He just didn't give a fuck.

He took one of his hands and let it trace gently across his stomach. He still had his abs, but they were less defined and didn't look as harsh, there was also a softness around his torso that just wasn't there before. His waist was a little smaller too, which wasn't saying much but his hips were definitely wider. He didn't..exactly hate any of it.

He brought his hands up and carefully traced under his breast. He stopped for a moment when he touched them, they were soft, nothing like his usual pecs and it just hit him how fucking weird this was. Why wasn't he freaking out more though? He should probably be freaking out more, right?

It just didn't seem as weird as it probably should have. Don't get him wrong, it was fuckin weird, but it didn't feel..unnatural.

Katsuki felt his breasts in his hands. They weren't big at all, but a nice handful. People had always joked about his pecs and called them breasts. Now he actually had them. They were bigger than Kyo’s but not nearly as big as Yaoyorozu’s breasts. “F..Fuck..” He sucked in a sharp breath when he accidentally brushed one of his nipples with the pad of his thumb, why the fuck were they so sensitive now? Were all women's nipples sensitive like this? Yaoyorozu..

His face immediately flushed and he felt shame creep up his body. Nope. Not thinking about any of that. He was not that little grape shithead or Pikachu. Nope.

He took a deep breath. Okay..Okay..moving past all that.

He watched himself in the mirror. Was it weird that he thought he was pretty? He'd never thought of himself as hot or handsome before. He knew to others that he was good looking, but he had never particularly cared. This..felt a little different.

He let his eyes travel down his toned stomach to below his waist. What the hell was he supposed to do with that? Hell, how was he supposed to pee? Was he going to have to sit down to pee every time now? That was actually irritating. That seemed like the biggest downfall of everything so far.

He was just looking at himself all over when a knock startled him. He cursed under his breath. “Fucking hell.” He made sure his voice was even as he started grabbing clothes. “Just a fucking second.”

A very familiar voice came through the door. “It's just me Bakugou. I brought you some things that you'll hopefully like.”

He instantly felt nervous that it was Yaoyorozu but then he just chastised himself. “Calm the fuck down, idiot. It's just Yaoyorozu.”

It wasn't “just” Yaoyorozu though, but he didn't want to think about that right now. His nerves were already frayed.

He slipped on his clothes and opened the door where Yaoyorozu was holding two bags in her hands. He let her in and she set them on his bed. “I made you a bunch of things that I hope fit and that you like.”

He watched as she reached into one bag and pulled out some basic black track pants, a couple pairs of shorts, a few basic shirts and tanks and a couple pairs of boxers. He picked up a few things and looked at them. Everything looked like it would fit. It was his basic style but just a little smaller so everything would fit. “How'd you know my measurements?”

She beamed a smile at him. “I used Mina as an example. With her growth spurt over the last two years, you two are pretty close to the same height and have similar builds and body types even before you..um..changed. I guessed on what I couldn't figure out.”

Katsuki nodded. “Makes sense. T..Thanks.” Fuck, he stuttered again. Well, tripped over his words anyway. He then looked at the other bag. “What's in that bag?”

He looked back at her and he could see her slightly blush. “I didn't know if you'd prefer masculine or feminine styles of everything so I made both. I know you're used to masculine clothes but I figured the feminine clothes could give you..um..more support.”

More support? He raised an eyebrow as he watched her bring a black sports bra out of the bag. A bra? She wanted him to wear a bra??

The more he thought about it though, the more it made sense. He'd need the support and he couldn't just have his..breasts going free under his school uniform.

Had he made his point clear that this was fucking weird?

He embarrassingly grumbled, “M..Makes sense.” God damnit Katsuki, get your shit together!

Yaoyorozu had slightly flushed cheeks as pulled out more clothes. There were some more feminine cut joggers and a pair of leggings. There were several types of shirts. Some more loose and some more form fitting. A couple pairs of shorter shorts.

Then his eyes widened when Yaoyorozu pulled out several pairs of panties. Did she really think he'd wear panties? What was she thinking?

She finally turned to face him, cheeks completely flushed. “I..I just wanted to cover everything. Plus I have some scrunchies in there because I noticed your hair got longer and I feel like scrunchies would be best for how thick it looks. I also made you a boys and a girls uniform for school and a new hero gear. I know we only have a couple months left and we're only in classes a couple times a week now, but just in case. You don't have to keep any of them if you don't want to!”

She seemed to speak the last part out quickly, probably wondering what he was thinking.

He looked at the feminine styled clothes. He didn't exactly hate anything. They were still in his style of clothing, mainly black and not too complicated. Some of the items even looked..comfortable. Would it really be that weird if he wore them? It wouldn't be that weird, would it?

She must have taken his contemplation as an answer. “I..I can take them back if you don't like them. No worries!”

He panicked. He didn't want her to take the other bag of clothes. “No!” He closed his eyes and took a breath. That was too much of a reaction. “I..I mean, it's fine. I may give them a shot, plus the extra support would be nice, my back is starting to hurt already. Plus..I appreciate it.”

Yaoyorozu smiled a wide smile even though her face was absolutely flushed. “It's no problem really. I like helping out. I..I guess I'll let you get settled.”

He watched her walk over to his door, but she seemed to stop and look back at him for a moment. “You're super pretty, Bakugou.” The taller girl then stuttered. “N..Not that you weren't handsome before! Y..You're just super pretty..I..I’m going now!”

Yaoyorozu was luckily out the door before she could hopefully hear the involuntary and embarrassing strangled noise he made.

He took a deep breath and turned back to the clothes. He was..curious. He stripped completely again and grabbed a pair of panties. They were a simple light blue. They were cute.

He stopped. He had never really considered panties cute before. Not in a sense that he was going to be the one wearing them.

Katsuki shook his head and stepped into them and slid them up his legs until they sat snug on his hips.

He immediately liked them more than he had ever liked boxers, and that kind of freaked him out. They felt comfortable, safe, and secure in a way he didn't know clothes could feel. They were just fucking clothes though, why were they having such a fucking impact on him right now? Why was he such a goddamn freak?

He growled as he grabbed the leggings and then slipped them on. He wasn't stopping to look in the mirror until he was finished. He was going to grab the sports bra and try it on, but he had heard Mina and Ochako bitch about bras for years now. He was not in the mood for all that so he just grabbed one of the sweaters Yaoyorozu had made. It was a light gray and it looked soft and cozy. He even tied his hair up in a messy ponytail with one of the scrunchies because it was long and heavy and it was getting on his nerves because he was already irritated and confused with the whole situation.

After he had everything on, he looked in the mirror again. Hair up in a ponytail, a soft white sweater, black leggings, and some pink socks. He looked so feminine. So soft and so..cute?

He really was pretty, and he didn't know exactly what to do about it. He also didn't know what to do with the warm feeling he had spreading throughout his chest.

What the fuck was actually wrong with him?

Chapter 2: Harassment and self esteem

Notes:

I hope everyone enjoys the new chapter.

Tw: sexual harassment

Stay gay my friends

Katsuki made his way into the elevator and hit the button for the lobby. He really wasn't in the mood to deal with the buffoons that were his friends and classmates but he needed to eat. He hadn't eaten at all today and it was quickly approaching his time that he usually started winding down for the evening.

He played with the hem of his sweater. He really didn't want to deal with the looks, whispers, and stupid questions he knew he was going to get but he needed to eat. He had a daily schedule to salvage. Hopefully Eijirou would still be down there to act as Katsuki's personal “leave Katsuki alone” guard shark.

Katsuki sighed as the elevator dinged and the doors opened, revealing most of the class still in the common room and eyes were immediately on him. Fucking Christ.

He didn't even hesitate, he made his way towards the kitchen. Katsuki made it about three steps before he heard Kaminari call out to him. “Bakugou! Can I take you out on a date?”

It sounded like it was said in gest which was better than the drooling and heart eyes from earlier, but still no less annoying. He could hear the snickers as Katsuki turned around and growled, stomping his foot. “Fuck off wall socket!”

Everyone went silent. Good. These fuckers needed to know he was still terrifying, but then a good portion of them started laughing. He crossed his arms and glared. “What the hell are you morons laughing at!?”

He could see Sero chuckling. “Dude, that was adorable. Probably the least scary you've ever been.”

Katsuki bared his teeth. “I'll show you fucking scary, stupid knock off Spider-Man. Just because I have tits now doesn't mean I won't kill you!” Where the hell was Eijirou? And now that he thought about it, where was Izuku?

That's when he noticed Mineta pop up from the couch. “Speaking of tits, you've got a great set there Bakugou.”

Katsuki looked down and noticed he was pushing his breast together and making them more prominent by crossing his arms so he dropped them and glared. “Quit looking at my tits!”

Mineta smirked, “I can see your nipples through your sweater.”

Katsuki crossed his arms and made sure to cover his breasts this time as he heard four different smacks as Mineta yelped. There were usually at least six, but that's when he noticed Yaoyorozu and Kyouka weren't in the common room.

This wasn't the first time Katsuki had been objectified because of his looks, but this time felt different. People weren't seeming to take him seriously now that he was in a women's body. They thought his anger was cute, and Mineta, who usually avoided Katsuki and kept his nasty remarks to himself, felt bold enough to talk about his new assets. It felt bad.

Katsuki felt his lip start to tremble. Why the fuck was he this emotional? Don't get him wrong, he was usually emotional, but he could cover it up with anger and people usually left him alone before they could see him cry, but now that wasn't working. He felt so fucking exposed.

Before he knew it, someone was grabbing his hand and pulling him along towards the kitchen. It wasn't until he saw pink hands wiping his face did he realize Mina had been the one to grab him and that he was in fact, crying.

He muttered as he let Mina wipe his face. “Stupid purple pervert.”

Mina gave a sympathetic smile. “Like you tell us all the time, he doesn't matter, but that doesn't change the fact of what he said was harassment.”

Katsuki shook his head. “I..I didn't get fucking harassed. I'll k..kill him.”

Mina's look turned stern. “He harassed you and we're going to do something about it. Let's tell Aizawa, he always listens. He told Mineta in first year to cut the crap or he'd be expelled. He's mainly left our class alone since then but I know he's still harassing others, I just don't have proof. What he said to you shows he hasn't changed, he's just been hiding it. Just like you've told us before, you don't deserve to be talked to like that.”

Katsuki knew he could tell Aizawa. His scruffy-faced guardian would take care of it in a heartbeat, but Katsuki didn't like being a bother and he could handle himself. “I..If it happens again. Then we'll go to my da..Aizawa.”

Mina sighed but eventually nodded. “Okay but I'm holding you to that, girlypop.”

Katsuki rolled his eyes. That dumb nickname. Mina has been calling him that since they met. Katsuki would never admit that it always made butterflies erupt in his stomach. He'd never admit it because it always confused him and it was embarrassing.

It was whatever.

He shrugged. “It just felt different. It felt like they weren't taking me seriously out there. It felt like Mineta only said what he said because of the body I have, that they think I'm weak or something now and that's not the case. Women aren't fucking weak. Especially the ones in our class, and right now, at least physically, that means me too.”

Katsuki had gotten used to people not taking his threats seriously, well because he didn't really mean them. When he was tired and pouty and he told someone to fuck off and die, people knew he didn't mean it, because he didn't. Out there, that had been different. It felt different. He wanted them to leave him alone and they didn't. It made him feel like they all thought he was lesser now.

Katsuki had heard the “locker room talk” from some of the guys before. Some of them truly thought that since they had grown bigger and stronger that the girls couldn't compete with them when in reality, that just wasn't the case. Katsuki knew that the girls in class, especially Mina, Ochako, and Yaoyorozu, could easily wipe the floor with most of the guys.

It had all just felt extremely demeaning in a way that Katsuki was not used to.

He had never let someone bad mouth the girls in class or the women in general that were around him, but after dealing with this, he was really going to start kicking in teeth when it came to people being stupid and shitty towards women.

Katsuki heard the front door slam open and then he heard a very familiar voice that was usually extremely cheery, but was now intensely pissed off. “Mineta! Where are you!?” Eijirou.

Mina winked at him. “Someone may or may not have let Kiri know what just happened out there.”

-

Upstairs, Momo screamed into her pillow as Kyouka rubbed her back. It was very undignified and immature, but right now Momo just didn't care. She could hear Kyouka chuckle above her, “You ready to talk about it yet?”

Momo sighed into her pillow and eventually set up. She threw her hands out and groaned. “It's Bakugou. He's just so..so..”

Kyouka lifted an eyebrow, “Hot?”

“Yes!” She flopped back on her king sized bed. “He's always been hot, but now, he's just on another level. It's no secret that I prefer women, but there's always been something about Bakugou that's always drawn me in. Him with that body now..it's driving me crazy. He has no idea how hot he is.”

She dreamily sighed as she looked up at the ceiling, trying to keep Kyouka from seeing her blushing face. “When I was in his room earlier, and as he stared at me with those piercing red eyes through those new long lashes, I just wanted to kiss him. I wanted to grab him around the waist or push him against the wall, and I wanted to kiss those plump and pouty lips until they were bruised and swollen.”

She covered her blushing face with her hands and groaned again. “Listen to me! What's wrong with me?”

She could hear Kyouka snort from beside her. “You're a young woman. There's nothing wrong with you. You're eighteen not eight hundred, so cut yourself some slack. You have a crush, a pretty big one at that. It's not a crime.”

Momo sighed, “The things I'm thinking about are not proper, and definitely not ladylike. They're inappropriate.”

She could almost feel Kyouka’s eye roll from how hard the shorter girl rolled her eyes. “Mo, you're allowed to be a little improper. You don't have to be perfect all the time. You can have all the nasty and raunchy thoughts you want, they're your thoughts. You're not doing anything wrong, they're just thoughts.”

Momo rolled just enough to see Kyouka shrug. “Besides, maybe he has the exact same thoughts about you.”

She scoffed. That was a nice thought but it was preposterous. Momo knew that she was smart, the top of the class actually, and she had come a long way in the confidence department when it came to her strength and her abilities, but that confidence didn't always carry over to other things. “Bakugou is not sitting around thinking about me.”

Momo poked her own stomach, she had noticed in her second year that being a little bit bigger and a little less muscular helped with her quirk, made it stronger and lasted longer, so she tripled her calorie intake. She was still physically strong but she had definitely gotten chubby over the last year. More than she had meant to. “I've let myself go.”

She had a muffin top and love handles now, and her thighs and rear end had definitely gone from firm and toned to outright fluffy and squishy.

Momo had been happier at first, she liked how she looked with a little more weight on her, but it had snowballed so quickly she couldn't stop it. The only positive things now were that she had an excuse to change her hero costume and Mineta and most of the other boys stopped ogling at her every time she breathed.

A hard flick to her forehead brought her out of her wallowing. “Hey! What was that for?”

Kyouka was giving her a stern look. A look she had seen so many times now. “You were spiraling, stop it.” Kyouka gently sighed and motioned for Momo to come to her.

Momo did as she plopped her head down in the shorter girl’s lap and let Kyouka thread a hand through her hair. “You're working hard on where you want to be Mo, and I know you'll eventually find the balance that you're happy with. Plus you and I both know that Kats doesn't give a shit about looks anyway. I know he appreciates the way certain people look but that's not his main focus. All Katsuki cares about is how strong someone is and how hard they push and take care of themselves. He cares about drive and character above anything else, two things you have an abundance of when you don't get stuck in your own head.”

Momo considered it for a second but she just couldn't wrap her head around that someone as amazing and attractive and incredible as Bakugou could possibly have thoughts about someone like her.

It's not like she thought Bakugou was shallow, she just didn't see a lot in herself at the moment. She hadn't for a while now.

She shook her head. “I'm fat, I'm meek, I'm not as confident as I should be, and I know I come across as arrogant and stuck up when I don't mean to. Bakugou probably thinks about people like Kirishima, Ochako, or Mina.”

Kyouka was the one who shook her head this time. “First, I can tell you for a fact he doesn't think about Kirishima like that, well not anymore. They had their little thing in first year but they both decided it just wasn't working. Now they have this weird eternal platonic soulmate thing going on, kind of like how Kat and Midoriya have their forever connected bond thingy. Secondly, Kats and Ochako are friends but it's based purely around respect and who can punch the other one harder. Third, Katsuki and Mina are like siblings. From his own mouth, Mina is his annoying ass little sister that he would kill for but would rather eat his own foot than tell her that and inflate her ego. His words, not mine.”

A hand stroked softly through Momo’s hair, “And fourth, you're none of those things you said you are. You're not stuck up and arrogant, you have a hard time relating to people sometimes but you're not stuck up. You've gained more weight than you originally wanted, but you're not fat and you're working so hard to get to where you want to be again. Also, you're quiet and a little introverted, but that doesn't make you meek. Plus you're confident, you just sometimes have some trouble finding it.”

“Katsuki thinks you're amazing, and you should to.” It was whispered so very lightly, but Momo heard it.

Momo shot up from her position and looked at Kyouka with wide eyes. “He does? He really does?” Momo knew that Kyouka was close to Bakugou. She had been brought into the blonde's small group last year.

Kyouka looked around in a panic and wouldn't meet her line of sight. “I..I..shit. Katsuki will kill me. I didn't say anything, okay?”

Momo crawled over so Kyouka would have to look at her. “Does Bakugou talk about me? What does he say?”

Kyouka still wouldn't look at her. “Mo, I really can't say anything. I promised Kats I wouldn't.”

Momo could tell Kyouka was starting to get uncomfortable so she backed up. “Sorry Kyo. I understand.” She did feel a little hope bloom in her chest though. Bakugou was talking about her to some degree and he had at least called her amazing at one point. That made her feel giddy.

Did she actually have some kind of chance with Bakugou?

Chapter 3: Master plans from the dumbest asses

Notes:

I hope everyone enjoys the chapter! I'm trying to keep this one serious to a degree but also light-hearted so I hope it's coming across that way

Stay gay my friends

Katsuki felt so strange as he ran through the morning fog. It was so weird to have the extra weight on his chest as he ran but he was extra thankful that Yaoyorozu had made those sports bras because they were coming in so clutch right now.

It wasn't as weird as he thought it may be to wear a bra, it was definitely an inconvenience but it wasn't as strange as he anticipated.

The only two things that really irritated him about his new body, physically at least, was sitting to pee every single time and how heavy his hair was now. Katsuki made sure to always stay hydrated so he went to the bathroom pretty often, and sitting to pee every single time now was just bothersome, especially when he was half asleep in the middle of the night. There had been two close calls last night and he was still not happy about it.

Then his hair, hell, his hair was so fucking heavy now and it kept getting in his face. He honestly liked the way it looked but it was so fucking annoying that he didn't know if it looking pretty and making him feel weirdly nice was worth the pain of dealing with it.

At least Ochako and Mina helped show him how to properly tie it up last night. He hadn't originally wanted to stay down in the common room even long enough to finish his dinner, but Kaminari had been threatened into silence and Mineta had been given a gnarly busted nose and black eye before being banished from the common room, so he stayed long enough for the girls that were present to give him tips on how to survive the week.

Plus Izuku had called, very apparently in a panic after finally getting the news about what had happened. It took ten minutes for Katsuki to reassure the nerd that he was fine and that he should stay and enjoy the weekend with his mom.

The green haired cry baby cared way too much about other people, even if Katsuki was glad he was one of those people.

Katsuki had gotten so lost in his own head that he didn't fully register that Eijirou was nudging him as they ran, until Eijirou had to physically grab him and stop him from running into a tree branch that he ducked every other morning run.

They almost fell but Eijirou steadied them before they could tumble over. “Sorry dude, but you completely zoned out. You almost hit the low hanging branch. Are you feeling okay? We can head back if you need.”

Katsuki glared for a moment about the suggestion of quitting their run early, but it fell pretty quickly. Katsuki had a lot of things racing through his head, and he honestly needed to talk about them, at least somewhat. “Goddamnit, alright. Promise not to tell anyone else?” He knew Eijirou wouldn't, but it was his way of letting Eijirou know that it was about to be a more serious conversation.

Eijirou nodded, “You know I won't.”

The two of them sat on the nearest bench that lined the trail they ran every morning. Katsuki blew a loose strand of hair out of his eyes that must've fallen out of his ponytail. “I feel off.”

He could see Eijirou scrunch up his eyebrows. “Like you feel sick? Or is this about what Mineta said last night? We can still go to Aizawa if you'd like.”

Katsuki snorted, Eijirou was always so genuine about helping him. He'd always feel fortunate to have Eijirou in his corner. “No, none of that. I..I..” How did Katsuki even want to say this? How did he explain that he was feeling more at peace in this body than he ever had in his original one? What the hell did that mean? It confused and angered him, Katsuki hated not understanding things.

He clenched his fists, as little curls of smoke whisped up through the wind. “I..I feel so fucking weird. W..Why do I actually feel like this body feels more right to me? What does that fucking mean?”

Katsuki watched Eijirou's face go from surprised to concerned to that look of pure adoration and acceptance that made Katsuki fall for him during their first year. “Before I say anything, answer this, how would you feel if you were stuck like this for the rest of your life? Would you hate it?”

Katsuki scoffed, “What kind of question is that? Of course I would ha...” He stopped. Would he really hate it though? If he stopped bullshitting himself for five seconds, would he really hate it if he stayed like this forever? Sure, he'd hate parts of it, like dealing with shit like what Mineta had pulled the night before, but would he hate everything else? Or would he miss it?

Would he really miss the fluttery feeling he got every time he looked in the mirror now? Would he miss the giddy feeling that settled in his chest when he slipped on clothes now? Would he miss the gentle curves and softness of his skin? Or how soft and light his voice sounded in his own ears?

Fuck. Yeah, he would. He really would.

This quirk was really fucking with him.

Katsuki sighed, “I..I wouldn't hate it. I would hate some aspects of it, but I really wouldn't hate it all together.” He looked up at Eijirou, “What the hell is wrong with me?”

Eijirou slung an arm over his shoulders and Katsuki let himself lean into the big bastard. “There's nothing wrong with you, I just think you're figuring stuff out about yourself, and that can always be really scary.”

Katsuki frowned at his shoes, “What the hell am I figuring out? That I like being a girl? That's not going to do me any good when the quirk wears off. That's just going to fuck me up even more. In six days, I will just go back to being Katsuki, and now I have all these fucking thoughts in my head. It's not like I can just stay a girl forever.”

As he sat there, he felt Eijirou lightly headbut the side of his head. Katsuki growled lightly, irritation clear in his voice. “What shark face?”

Eijirou was giving him a soft grin. “Your body isn't what makes you a girl.” Katsuki felt Eijirou poke him in the forehead and then the chest, right above his scar. “Those two things are what make you a girl, if that's what feels right.”

Katsuki growled, “I don't know what feels right though! All I know is I feel pissed off, confused, and..and fucking terrified!”

He let out a ragged breath that signaled if he didn't calm down soon, he was going to probably blow something up and then cry. “I..I can't be a girl. People have already shown they're not going to take me seriously, and I have to be the best. I have to be number one, to show everyone how good I am. How hard I've worked. I can't do that if I'm some kind of confused..freak!”

His breathing was becoming even more ragged. “What am I supposed to do when I change back? Throw on some clothes and say I'm a girl? Nobody will take me seriously. I can't lose everything I've worked so hard for even if it could possibly make me happier..”

Large hands enveloped his own with an activated quirk. It was a sign for him to release a small blast into Eijirou's hands. It always calmed him down when he was on the verge of a panic attack.

Eijirou then deactivated his own quirk and started massaging his palms, another thing that calmed Katsuki down. “Okay, there's a lot to unpack with that. First thing, you're questioning yourself and that's completely okay, but it's not something you may immediately have an answer to. It may take time for you to really figure stuff out if there is something there. That's valid, it's not a race. Plus you got to remember how and where you grew up. That was not a safe environment to explore these types of feelings. Second, just say you do come to the conclusion that you're a girl, there's a lot of things you can do to make your body match how you feel. Even when this quirk wears off, there's ways to make your body match how you feel again. It all just depends on how you feel and what you want.”

Katsuki felt Eijirou slightly squeeze his hands. “Third, when it comes to your own personal goals and feelings, nobody else matters, at least in this context. You chase what you want, and I know this is probably discombobulating and really scary, but I know that's not going to stop you. Stupid and cruel people's opinions don't matter. You've got to do what makes you happy, Kats.”

There were a lot of emotions swirling in Katsuki at the moment and he really just wanted to scream and probably cry, so he did what he usually did, deflect. “Where the hell did you learn the word, discombobulating?”

He watched as Eijirou cracked a grin and lightly shoved him before yanking him back into a hug. “Iida taught me, but stop deflecting. Just take your time with this. There's no right and wrong answer, ya know? It's whatever feels right for you.”

Katsuki let Eijirou hold him for a little bit. “I know you're sweet and a cheese ball, but you're really accepting of your best friend, your violent best friend who you've called manly for the last two and a half years who may want to be a girl all of a sudden.”

Eijirou headbutted him again as they stood to finish their run. “You're not violent, and when I say manly it's gender neutral, but if you ever wanted me to stop saying it, I would. Plus you know none of this would change how I admire you, and you also know I have two amazing moms, but one of them also happens to be trans.”

That made Katsuki feel like shit. He had forgotten about that. Eijirou’s mama was an absolute angel of a woman. “Ei, about that freak comment..I didn't mean it like that. Trans people aren't freaks. It's just different when it comes to me. I'm..I’m not..I don't..”

Eijirou gave him a small smile then, “Katsuki, you're fine. I know you didn't mean anything by it. You're just lost, but I know you'll figure it out, and you know you've always got me to help. These feelings are sudden and rightfully terrifying. I know you Kats, It's hitting you all of a sudden, well it's kind of all of a sudden. I've had my guesses for a while now.”

That made Katsuki pause. “What do you mean that you’ve had your guesses?”

Eijirou just shrugged, “I'm one of the very few people that you’ve let see every side of you. I notice things, Kats, that's all I'm saying.”

The big bastard started running before he could ask anymore questions and it took Katsuki by surprise so he couldn't even give chase right away. “You big red bastard! What do you even mean by that!?”

-

Momo was sitting in one of the rocking chairs they had on the porch of Heights Alliance. She loved getting up early and just enjoying a nice cup of tea.

She was rocking in the chair as she watched Eijirou come running down the path, laughing and that's when she noticed Bakugou was right behind him. The blonde was in an absolute dead sprint with a look of pure determination on his face.

She could only watch on in amusement as Bakugou lunged and sent him and Kirishima tumbling into the grass.

Momo laughed just for a second before she involuntarily sucked in a breath and almost choked. Bakugou had a devious grin on his face as he pinned Kirishima to the ground. She could see sweat drip down his neck and into his sports bra, a sports bra that was doing a great job of holding up Bakugou's new..assets but was also slightly revealing of those new assets.

Momo tightened the grip on her cup. “O..Oh my..”

“Wishing girlypop was pinning you to the ground like that?”

Momo jumped slightly as she turned to see Mina smirking at her. “W..What do you mean?”

Mina just continued to smirk. “It's not the first time I've caught you making lovey dovey eyes at blasty babe, except this time it looked like you wanted to eat him.” Mina made her way over to the other chair and sat down. “You should talk to him about it.”

Momo looked down at her tea, her face warm from being caught more than from the heat from the tea. “Kyouka says the same thing.”

She looked over to see Mina smiling. “Kyo’s smart like that.”

That they could agree on.

Momo sighed. “I like Bakugou.”

Mina snorted, “I know that Yaomomo, most of us do. Most of us have been waiting on you two to finally get your asses in gear for like the last nine months.”

Momo looked over at her pink friend. “You say that like it's so simple. Like if I just told him how I felt, that he would just accept and return my feelings. I'm not like you or Kyouka. I can't just go up to him and say these things. I don't have it in me.”

Mina's look turned soft, “I'm saying it like that, because it really is that simple. Don't overthink it, and If you don't believe me, watch his eyes. They soften up when he looks at the people he really cares about.”

The pink girl then made a disgusted face. “Or just watch his face when you're in the gym together. I've seen the way he looks at you in there. He looks at you..well kind of how you were looking at him when I came out here actually.”

Momo felt her face heat up again as the two of them turned to see Bakugou trying to choke Kirishima. She could see Kirishima grinning and laughing as he batted the blonde's hands away. They weren't too far away so she could hear Kirishima speak through his laughter. “You know Yaomomo is watching us right now, right?”

Bakugou paused and looked over at her and she felt her face flush all over again as she could see Bakugou's face do the same.

Bakugou then squealed as he was unknowingly tossed aside by Kirishima.

It seemed like the red head was immediately making a break for the doors. He called over his shoulder, “You're not usually that distracted, Kats!”

As he passed them, Momo could have sworn that he winked at her before he gave a quick look back at Bakugou. “Kats, I'll grab us some water and a couple protein bars!”

Bakugou was still laying in the grass as he shouted. “I'll kill you!”

It was only a few moments later and Kirishima was standing next to her and Mina again. “Hey Yaomomo, I think that gremlin messed up my ankle when they tackled me. Can you bring em a water for me?”

Momo was never one to not help a fellow classmate and friend. She put her tea down on the small table next to her. “Of course, Kirishima, and make sure you put some ice on that ankle as soon as you can.”

She took the water bottle from him and made her way down the porch. It was only when she heard Mina's giggles did she know that she had been tricked. Kyouka had been so secretive but Mina had laid everything out into the open. Were they all in on this?

She didn't dare turn around and show them her flushed face. She'd show them one thing though, she could do this. She could talk to Bakugou without the help.

She made her way over to Bakugou, and she immediately felt her throat dry up. The blonde had on the small pair of running shorts and one of the tanks Momo had made for him. The shorts showed off muscular legs that led up to pale muscular but still soft looking thighs. Bakugou's tank had also been rucked up in the previous wrestling match apparently because Momo was also getting a close up of sweaty abs and a tight stomach.

She was going to die. Scratch that, she may already be dead and this was her heaven.

Momo traced over pale legs with her eyes again as the thought hit her. ‘I want in between those legs. I want to do so much between those beautiful legs.’

She squeaked as she forced her eyes anywhere else but the blonde in front of her. She stiffly held out the bottle of water. “B..Bakugou? I brought you some water. Kirishima said his ankle was hurt.”

The blonde shot up to a sitting position. There was a shocked look for a moment before he glared past her to the porch. She heard him mumble under his breath. “That red fucking bastard and that pink ass little shit.”

He sighed before he looked up at her and took the water from her. His hands were slightly shaking. “Thanks Yaoyorozu.”

She finally met his eyes and his entire look immediately seemed to soften.

Oh.

Oh! Maybe Mina and Kyouka were right and she really did have a chance with Bakugou.

Her chest warmed as she felt a sudden rush of adrenaline. “C..Call me M..Momo, please.” She then rushed out the following sentence. “Only If you would like to anyway!”

Red eyes locked onto hers again for a moment before the blonde was grinning ever so slightly. “Alright then, Momo.”

Chapter 4: I don't want to be your boyfriend

Notes:

Hopefully everyone enjoys the chapter!

Stay gay my friends

“Momo, don't look now, but a certain blonde is checking you out again.”

Momo sat up after she ended her reps at the sound of Kyouka's voice and was met with the sight of Baku..well, Katsuki now, staring her down. H..He looked like he wanted to eat her.

O..Oh my..

She felt heat bloom over her face and..somewhere else. She clamped her legs together as nonchalantly as she could. That look..that look was doing so much to her. “K..Katsuki needs to stop staring at me like t..that.”

Kyouka and Mina were the only two around that were close enough to hear her. She could hear Mina giggle. “So it's Katsuki now, huh? What's the matter Yaomomo?”

Momo shot her a glare. “S..Shut up. You know exactly what's happening and why.”

Kyouka chuckled next to her. “Mo, Kat looks like he wants you for breakfast. Use it to your advantage. Show him what he's missing and kick his ass into gear. You two could be making out by dinner tonight if you make your move.”

Momo bit her lip as she nodded and laid back down on the bench, ready for Mina and Kyouka to spot her again. Maybe she could give Katsuki just a little show, just to see if he really did want her. She hated always second guessing herself but she wanted to make sure.

As she continued to work out though, she kept sneaking glances at Katsuki, and every single time he looked like he was ready to take her right here and now. She was feeling her confidence grow as she could feel Katsuki's eyes bore into her as she continued to push herself further and further.

She missed this feeling. The feeling of being confident in her own skin. The feeling of being wanted for who she was. It was such a beautiful feeling. She wanted Katsuki to keep watching her.

After another couple sets, she looked over to see Katsuki crossing his legs as one hand was clamped on a towel so hard she could see it lightly smoking. Was Katsuki..Was Katsuki truly aroused? Had she really aroused Katsuki? That was an intoxicating feeling and her thoughts began to run wild.

Their bodies shoved together, both of them sweaty as they made out in the shower. Pinning the blonde to the shower wall as she dove in-between those beautiful legs and tasting every little drop that Katsuki would give her.

Momo could just imagine worshipping every single inch of Katsuki’s body, for hours and hours at a time. Those beautiful legs, marvelous thighs, incredible abs. She wanted every inch.

Someone snapping their fingers in her face brought her out of her fantasies. She immediately felt herself flush as she could see Kyouka smirking at her. “Pull yourself together before you drop the bar on yourself next time. Fantasize later, pervert.”

Her face felt like it was on fire from their teasing. “I’m n..not a pervert!” She whisper shouted as Kyouka and Mina broke down into a fit of giggles at her expense.

She did know one thing, she was going to have to take care of herself later tonight. She had been trying to not touch herself while thinking of Katsuki because it felt inappropriate, but she didn't know if she would be able to stop herself tonight. The hungry look Katsuki had been giving her would fuel her thoughts and fantasies for weeks.

-

Katsuki didn't know what the fuck was going on. This was the third day of this quirk fiasco and her body was feeling weird. She..He.. He had been watching Momo workout from across the gym when he felt a strong but incredibly weird feeling in his lower stomach. It was like a tightening feeling.

His breath felt like it was becoming faster and more shallow, and he could feel his nipples getting hard under his sports bra. He felt weirdly full and heavy so he tried crossing his legs but that was an immediate and very apparent mistake.

A little sound escaped from his mouth all on its own. It was a light and breathy little sound and apparently he wasn't the only one who heard it.

Ochako was next to him. The two of them usually partnered up together in the gym. The brunette side eyed him and he purposely ignored the look. “Katsuki, are you okay?”

Katsuki fidgeted and another little sound involuntarily left his mouth. “I..I’m fine..mmmph..f..fuck… okay.. I don't know what's wrong with me.”

He could see Ochako look him up and down and then she must have followed his line of sight where he had basically zoned in on and had just been unforgivingly watching Momo workout. Ochako let out a little gasp. “Katsuki, are..are you horny right now?”

Katsuki turned to glare at her before he half shouted under his breath. “N..No!” Wait. Was he? Was this what it felt like when a woman got aroused? It felt so much more overwhelming than getting aroused with a dick, but in a good way. It was overstimulating but it also felt kind of incredible. He could feel this through his whole body, not just his dick like he was used to. “Maybe. Fuck, I don't know. It was easier to tell when I could just look down and see what was going on down there.”

His glare turned even deadlier as Ochako started giggling. He gripped the towel in his hand even harder. “Shut the fuck up! It's not funny. I feel like a fucking creep.”

Ochako continued to smirk but she did stop giggling. “You're not a creep. It happens. Just seeing Tsu get undressed used to make me want to jump her bones, still does honestly. Anyway, Yaomomo is hot and honestly I'd be a little more shocked if you weren't a little wet by seeing the woman you're clearly thirsting after working out and being a badass.”

Katsuki sputtered. “W..Wet? What the hell are you talking about?”

That's when Katsuki felt something slide down her leg. His leg! Fucking Christ this was beyond confusing. He needed to get his shit figured out. Also, d..did he just piss on himself because it sure and the hell didn't feel like sweat. Was that..was it because he was aroused? He could get so aroused that it would just drip down his leg? He even had underwear on. What the hell!?

He needed to get out of here. He needed some kind of distraction and some place that didn't have Momo in it. It was like she was radiating some kind of pheromones and he was addicted. He needed fresh air. Now.

A whistle was blown and Katsuki released a breath he didn't even know he had been holding. Then he could hear Aizawa's exhausted voice. “Alright, we're heading outside to Ground Beta. Quirkless sparing, round robin style. I pick your first opponent.”

Katsuki smirked. This is exactly what he needed. Punching someone in the face would easily clear his head. He listened as Aizawa called out names until his was finally called. “Bakugou and Yaoyorozu.” His smirk immediately disappeared.

Oh fucking hell. He was so fucked.

What had he done in the past to deserve this treatment?

Shit.

Nevermind, don't answer that.

-

Momo dodged a quick punch and rolled away.

Katsuki was distracted. His punches were sloppy and he wasn't being anywhere near as aggressive as he usually was in quirkless combat.

Something was up with him, and that concerned her but she was also about to use it to her advantage to end this spar so she could ask him what was wrong.

She waited for her opening and went for it. It took less than thirty seconds and she had the blonde pinned underneath her. Momo didn't think about it as she slid a knee in-between the blonde's legs to reach up and pin his arms at the wrists and that's when she came in contact with a very warm center and Katsuki made a sound that she had only heard in her dreams.

It was a breathy whimper and a light moan of her name. “M..Momooo..”

Momo felt her grip on Katsuki's wrists involuntarily tighten as she felt her own breath quicken. “Katsuki..d..did you..?”

Momo tried to remove her leg but she felt Katsuki's thighs clamp down around her leg like a vice. “D..Don't fucking m..move yet. J..Just give me a second to catch my breath. P..Please. Fucking hell, I don't know what to do.”

Momo tried to keep as still as possible as her own mind raced. They were luckily in their own little section of Ground Beta. She could hear their friends off in the distance but luckily nobody could see or hear them right now.

It was clear that Katsuki was aroused. She could feel the warmth and dampness on her thigh from Katsuki's clothed center. Plus those sounds. She'd remember those sounds for all her life. Katsuki had actually moaned her name. Her name!

It was taking all of her strength not to just lean down and plant kisses all over Katsuki's neck. She wanted to mark that pale skin and claim it as hers. Momo was almost shaking from just how much she wanted that scenario to come to fruition.

Momo heard Katsuki lightly gasp, “M..Momo..!?”

Apparently she had been so far in her head, Momo hadn't realized she had actually ducked her head and planted a kiss right under Katsuki's right ear.

She should pull back, she needed to, but she couldn't help herself. She gave Katsuki a second to refuse or to tell her to get off, and when he didn't, she planted another soft kiss, and then another, and a few more as she trailed down Katsuki's neck.

The blonde under her squirmed. “A..Ah..M..Momo..”

That's when she first felt Katsuki purposely grind against her thigh and they both let out their own moans as result.

Momo immediately went back to Katsuki's neck, this time biting certain spots, trying to figure out where Katsuki liked it the most.

Momo felt beyond intoxicated. She felt invincible. She broke away from Katsuki's neck just long enough to mumble praises she had wanted to tell the blonde for so long, right into his ear. “Katsuki, you're so beautiful. So amazing. So smart. You're everything I’ve ever wanted.”

She let Katsuki’s wrists go and felt hands immediately wrap around her neck. Katsuki tilted his head back, the muscles in his throat were taught and he had his mouth slightly open with his eyes half shut. It was like a gorgeous painting Momo wished she could immortalize forever.

Katsuki let out a slight whine, tilting his head up even further and presenting more of his neck. “M..Momo..p..please..” Those breathless whines and pleas were going to kill Momo, and she was going to enjoy every damn second of it.

Once again, Momo attacked the blonde's neck, speaking in between kisses and bites. “I've wanted this for so long.” She trailed her nose down Katsuki's jaw, smiling as she could feel Katsuki trembling. She felt like a whole new person. Where was this confidence coming from? “You drive me wild, p..pretty girl.” The words felt foreign on her tongue but Katsuki seemed to like them, and Momo did too.

Momo sunk her teeth down into a spot between Katsuki’s neck and shoulder. The blonde again ground down against her leg. “I like you so much, Katsuki. I've liked you for so, so long. I want you to be my boyfriend.” She was feeling things that she had absolutely never felt before and she never wanted it to end, it was letting her get all of her own feelings out without being beat down by her own insecurities and finally tell Katsuki everything she had wanted to tell him.

It was like a fantasy come to life, and then it immediately wasn't.

Momo felt Katsuki immediately tense up under her after she admitted she liked him and told him she wanted him to be her boyfriend. It felt like every single muscle in Katsuki's body went rigid all at once, and that's when Katsuki burst into tears.

Notes:

Just the lightest sprinkles of smut for now :3

Chapter 5: I want to be your girlfriend

Notes:

I hope everyone enjoys the chapter!

Stay safe my friends

One second Katsuki was on cloud nine, in absolute bliss as Momo touched him, kissed his neck, praised him, and then the next second he was involuntarily bursting into tears. It was like he had no control over his emotions or body, he just started crying. It was fucking embarrassing.

Oh who the fuck was he trying to kid, it's because Momo said boyfriend instead of girlfriend. He..fuck..she. She just didn't want to be seen as Momo’s boyfriend, she wanted to be her girlfriend.

As soon as Katsuki started referring to herself as she in her own head, everything immediately started to quiet down just a little. Her head was always just so fucking loud, but referring to herself as she seemed to quiet things down, just a little.

She had been going back and forth with this for the last couple days, especially since she had talked to Eijirou. She had been scared to admit it, even to herself, but hearing Momo say boyfriend apparently was the catalyst she needed. She was a woman. Of body and soul. Katsuki was meant to be a woman.

Katsuki had set up and was wiping her eyes, lightly sniffling when she realized Momo was standing a couple of meters away. Looking absolutely petrified. Good job Katsuki, the woman of your dreams would probably never want to come near you again. Fucking emotional mess. “M..Momo..”

They locked eyes and he could see Momo’s lip start to wobble. “Katsuki! I'm so so sorry! I..I should have asked or shouldn't have done what I did. I'm sorry! So sorry!”

Katsuki shook her head slightly and patted the ground right next to her. “Y..You don't have to apologize. I'm still processing everything. Just come here so I can explain everything the best I can.”

It took a moment for Momo to start moving, but she finally started to slowly make her way over until she was sitting down next to her. Katsuki took a deep breath and just plowed through what she had to say because if not, she wouldn't be able to get through it. “I'm a girl. Not just physically because of this stupid quirk, but like emotionally and mentally and shit. I..I think I'm trans or whatever. This fucking quirk has left me so fucking confused and I've been trying to figure out what it all means, and I had a full blown breakthrough at the worst possible moment. Everything you were doing was amazing. Beyond amazing. It's..It’s just that when you said boyfriend..I guess I just didn't like it.”

Katsuki wouldn't look up, she was too busy studying her shoes. “As soon as you said boyfriend, all I could think about was wanting to hear you call me your girlfriend instead.”

An uncomfortable silence hung in the air for a moment and Katsuki started to panic. “I..I know this whole situation is really fucking weird, trust me. It seems like you like me, but if you don't after that shitty bombshell then..” A hand being placed gently on her thigh stopped her rambling mid sentence.

She finally looked up at Momo who was now softly smiling at her. “I still like you, Katsuki.”

Katsuki could feel a goofy grin break out over her face, even though she knew she still had fresh tear tracks on her cheeks. “I like you too, Momo.”

Momo’s smile seemed to widen. “Just for the record, I don't think this is weird. I think it's really beautiful that you were able to find yourself even though this whole ordeal must be terrifying.”

Katsuki snorted. “It's been insane and confusing and downright terrifying, but I was able to find out more about myself. I think this part of me has always been there, at least somewhat. I was just never able to stop and examine how I was feeling.”

A light blush seemed to make itself known because Momo’s cheeks turned a little pink. “I've liked you for a while. For most of my life, I've just been attracted to women, but then all of a sudden on my first day of Yuuei, there you were and there was something about you that immediately drew me in, and it always confused me. You're a woman though, so now things make a little more sense. Maybe that's the energy that initially pulled me in.”

That made Katsuki think of what Eijirou had said. That he had his guesses before this. Maybe she really was trapped and just waiting for her chance to escape way before this whole quirk disaster.

Katsuki threaded her fingers between Momo’s. “I know I just had like an embarrassing ass meltdown, but could I kiss you? I've wanted to kiss you for a long time now.”

She watched as Momo’s other hand came up to cup her cheek. “Are you sure? Don't push yourself if you need more time.”

Katsuki was a hundred percent sure she wanted to kiss Momo. That she knew for certain. She leaned in and let her eyes flutter closed. The second their lips touched, Katsuki knew she wanted to kiss Momo a million more times. It was cliche as fuck, but kissing Momo felt magical. The butterflies, the fireworks, all of it. She felt all of it and she wanted to feel it forever.

Katsuki let one of her hands come up to caress Momo's cheek before sliding down her neck and resting it on her shoulder.

“I'm pretty sure that's not what Aizawa sensei meant by hand to hand combat.”

The two of them sprung apart immediately and Katsuki whipped her head towards the annoying and monotone voice that she had to hear on the daily and when on patrol. “What the fuck do you want Icyhot!? Creepy ass fucker!”

Todoroki and Shinsou were both just there staring at the two of them. Shinsou smirked at her. “The whistle blew, it's time to switch partners. You two would have heard that if you weren't over here sucking face. I'm so telling our dads.”

Katsuki glared at him. “You aren't telling them shit or I'll tell them that you constantly sneak over and stay with 3B just so you can fuck your boyfriend.”

Shinsou's smirk vanished as he groaned, “Fuck, I forgot you knew about me and Neito.”

It was Katsuki's turn to smirk. “Yeah fucker, who do you think covers for you ass at least once a week? Now both of you scram, we'll switch partners in a minute. Also, for future reference, I know you're both awkward as fuck and gayer than a rainbow but maybe next time don't stand there and just watch two girls make out. S’kinda fucking weird.”

Katsuki paused. She had just called herself a girl. To other people that weren't Momo or Eijirou! She cooled her expression though. They wouldn't think anything of it. They'd probably just think it was about the quirk.

Shinsou rolled his eyes. “You get turned into a girl for a week and you start throwing around gay jokes.” Katsuki went to open her mouth but Shinsou already beat her to it. He waved his hand in a dismissive manner. “I know you're bi, but you know what I mean. Shut up. Come on Shouto.” Katsuki released a breath, she was right. They seemed to just think she was talking about the quirk. She'd have to watch what she said a little more closely from now on.

Todoroki just looked between them for a moment before giving them an awkward wave, shrugging, and then he followed Shinsou away from them.

Katsuki rolled her eyes but cracked a grin as Momo began giggling next to her. “Sorry, it was my fault we kind of got caught. It was kind of exciting though. I've never done anything like that before.”

Katsuki snorted out a laugh and stood up, holding her hand out for Momo to take. “Nah, don't apologize. I'd do it again in a heartbeat.”

Momo grabbed her hand and Katsuki helped pull her up. Momo held onto her hand as they began walking towards the center of Ground Beta to find new partners. “I hope we get to do it again, the kissing I mean, not the getting caught part, I really liked kissing you.”

Katsuki felt that goofy grin spread over her face again. “I like kissing you too, a lot.”

The two of them made it almost to the center of Ground Beta when Momo stopped them, “Katsuki, before you go, I want to ask you. D..Do you want to be my girlfriend?”

Katsuki took a step forward, stood on her tiptoes and gently kissed Momo. They were both smiling when they separated. “Yes, I'll happily be your girlfriend.”

Katsuki was very much in a good mood later that day. She had figured out her identity and she had a girlfriend! A pretty productive day all in all, and a productive day always made Katsuki feel good. Plus she was going to see Momo later, so that was also a plus.

She was looking for Eijirou. He wasn't in his room so now she was down here looking for him. She entered the common room to find a lonely Eijirou which was odd. It was unusual to find the common room with only one or two people in it, unless it was early morning. “Shark face, where's everyone else?” She knew Momo was out on patrol. Plus her, Todoroki, and Izuku were off today. Same with Eijirou.

Eijirou grinned over at her as a piece of meat fell from his lips. “Chew your food, you nasty ass. You're not actually a shark.” Katsuki fondly rolled her eyes as she made her way over to sit next to him.

He finished the bite he had and set his bowl of food down. “Most people are at work or training as far as I know. Plus Mina and Jirou went to the mall. Midoriya and Todoroki are off on a date, so that just leaves us two.”

Katsuki nodded as she maneuvered so she was laying her head on one of his thighs. His hands immediately found her hair and she grinned. She loved when he played with her hair, and that had even been when it was short. Even after they broke up years ago, they had always been like this. Eijirou was just her safe person. She suspected he always would be.

She could hear him lightly chuckle above her. “I haven't seen you in this type of mood for a while. You're in a great mood.”

Katsuki smiled up at him, she loved that he said it as a fact. He just knew her that well. “I am. I got a girlfriend and I finally figured out I'm a girl all in one day. Started off embarrassing as fuck, but I'm pretty happy with the results.”

She watched his face go from shocked to even more shocked to completely fond within five seconds. He grinned at her. “I'm extremely proud of you, and I'm so happy for you too. It's nice to see you this happy and content. Plus about time you and Yaomomo finally got together. At this point I have to keep dying my hair red to get rid of the grey hairs because I've grown old waiting for the two of you.”

He laughed as she swatted at his chest. “Shut the fuck up..but thank you. I told her everything too. You two are the only ones who know. I don't know what I'll do after this quirk wears off but I'm going to figure it out. Whether I have to find another person with a quirk like this or even if I have to take estrogen and the other stuff I gotta do. I'm a woman and I want my body to match how I feel.”

Eijirou gently threaded his hand through her hair. “It's been a bit since my momma has seen him but she used to see a doctor who had a quirk that could change people like how this quirk did but it's always been permanent when he did it. I think you still have to go through a bit of like therapy and paperwork and all that stuff but it's an immediate transition when he does it. I'll talk to momma and see if she still knows if he's still seeing patients.”

That was perfect! It would be hard when this quirk wore off because of how she felt now, but if she could find that doctor, maybe it wouldn't be too long before she could feel like herself again. “You're the best, you know that? Seriously.”

He smiled softly at her. “You know I'd do absolutely anything I could to help you, Katsuki.”

Hearing her name made her remember the other thing she had originally been looking for Eijirou in the first place. “I want to change my name. I don't think Katsuki fits.”

Eijirou’s eyebrows rose slightly, “Yeah? Any name in particular you're thinking of?”

She felt her cheeks lightly blush as she looked down at her hands. Last night when she had been going over moments in her life that were probable signs of her screaming to be heard, she remembered a particular memory.

She couldn't have been more than five and she had snuck and grabbed one of her mom's skirts and blouses so she could be the lady civilian for Izuku to save while they were playing heroes.

She remembered looking in the mirror. She looked ridiculous of course, the clothes were way too big on her and she had to hold them to keep them on, but she remembered feeling an odd sense of joy mixed with longing.

She also remembered the “random” name she had come up with back then when she played a lady civilian.

It was a time when her hands used to produce only tiny sparks that shined and glittered like tiny fireworks. A time when she had never hurt a soul with her quirk. She looked back up to Eijirou. “My name's Kira.”

Chapter 6: Study date with Kira and Momo

Notes:

I hope everyone enjoys the chapter! I'm not the best when it comes to writing smut, but hopefully this is still good!

Stay gay my friends

Kira whimpered as she felt Momo attack her neck with kisses, the blonde dug nails into the taller girl's shoulders. “Mmmph! M..Momo..”

What had started as a study session and just overall hanging out so Kira could tell Momo about her new chosen name quickly had turned into a make out session, and this is where they were currently.

Kira was on her back with her legs slightly spread, enough that Momo had one legging covered thigh pressed against her pajama shorts covered center. Momo was stradling one of her thighs and Kira could feel her girlfriend slightly grinding against her and that was knocking Momo’s thigh right against her already aching center.

Kira felt so flustered and so hot that she felt like she was going to combust at any moment. The full and tight feeling was also back in her stomach and it kind of felt like she had to pee. Was she about to cum? That's what the Internet had said it felt like for people with vaginas to be close to having an orgasm. (What? It wasn't like she had any experience and she liked to be prepared.)

Whatever was happening, she felt like she could die again and this time she could die happy. Kira felt Momo suck a particular mark onto her neck that she knew immediately would bruise. “Y..You're purposely trying to m..mark me. Aren't you?”

Kira didn't particularly care, she just had to give her girlfriend a hard time. Honestly it kind of felt like a privilege to have someone as incredible as Momo mark her up. Which made her feel a tad guilty for a moment because she had never let Eijirou do that to her, and Eijirou was the most amazing person on earth.

Her thoughts were quickly washed away as she felt Momo smile against her skin. “You're so beautiful Kira, why wouldn't I want to show off how lucky I am to be the one that gets to touch you like this? Maybe I should sign every little mark on you to really let everyone know you're mine.”

Kira could feel herself leaving scratch marks down Momo’s back, even through her tank top. She loved when Momo was confident in herself. The taller girl was so amazing and beautiful and talented, and Kira loved seeing her feel that way.

She couldn't help but let out a little giggle that ended in a moan as Momo bit her neck again. “It will be one hell of a way to tell the class..Momo!”

They had decided to not hide the fact that they're dating but Kira wasn't going to tell anyone but Eijirou, Momo, and maybe Izuku, Mina, and Kyouka about her being a girl, for now at least.

Momo nuzzled up her jaw, peppering kisses along the way. “I love hearing you moan my name. Kira, c..can I..” There was a momentary pause before Momo continued. “C..Can I touch you in other places?”

Kira didn't even have to think about it. She eagerly nodded. “Y..Yes, please, yes.” Maybe they were moving way too fast by normal standards, but it really didn't feel that way. It felt so natural, and it didn't feel forced or rushed. Plus Kira had never really been one to be considered “normal.”

A moment passed before Kira felt warm hands travel under her shirt and ghost across her abs, and her back arched at the touch. Nothing had ever felt like this before. Every little touch from Momo felt like electricity running through her whole body but in the best way possible. Not like when that stupid Pikachu sneezed and ended up frying anyone in a three meter radius.

Hands continued to slide up until Kira felt a slight pause right before she felt the light touch of the pad of Momo’s finger brush against her right nipple. “O..Oh fuck.. That f..feels so good.” She had never expected her nipples being played with to feel this good.

She couldn't help but squirm under Momo’s touches as she let her girlfriend play with both of her nipples for a while. It was beyond euphoric but Kira also couldn't block out the extreme ache between her legs. She needed something, she needed something but she didn't know what.

Then it hit her, she wanted Momo inside of her. More than that, she needed it. She craved it. “M..Momo.. p..please.. I want you inside me.. I need you..” She figured she would find it embarrassing to beg and plead to be touched, but it really didn't feel embarrassing, and maybe because it was just with Momo.

Momo’s hands left her nipples and the taller girl cupped her face gently. “Are you sure, Kira?”

Kira nodded fervently. “I'm sure. I wouldn't want it to be anyone else but you. I want you to be the first one to touch me since I've finally felt like my true self. I want you. I need you.” She wanted Momo to be the only one to ever touch her like this again, but that was way too early on to say.

Momo kissed her lips, and smiled. “I’m honored, Kira, and I promise I'll be gentle.”

It took a few moments of shuffling around, but Kira soon felt a hand slide into her shorts and panties. She then heard Momo softly gasp. “Y..You're so wet, Kira. Your panties are soaked.”

Kira slightly arched her back and was able to give a little half smirk. “What can I say, the touch of a beautiful woman does that to a lady.”

Her smirk instantly vanished when she almost choked as she sharply inhaled when one of Momo’s fingers barely even brushed her swollen clit. She was already so close. She could feel it. She knew it wouldn't take hardly anything at all and she was going to cum. She just wanted to feel Momo inside of her. She needed to feel it. She wanted Momo to be the one to give her her first orgasm in a body that finally felt real to her. “Mmm..M..Momo c’mon, please touch me. I need to feel you inside me.”

She finally felt one of Momo’s fingers slide into her, and then a moment later, a second one. “F..Fuck. Fuck, f..feels so good.” She could feel it coming. She felt like a wire about to snap.

Momo was grinning into her neck. “You're so tight, Kira, but so wet for me. I can't wait to see the beautiful face you make when you cum.”

It didn't even take three pumps of Momo’s fingers and not even a full swipe against her swollen clit and she was cumming. “M..Momo.. Momo..babyyy!” The pet name rolled off her tongue like it was something she said on the daily, and it came out in a high pitched scream as she felt her back arch off the bed and she saw literal stars.

She felt such a flood of emotions flow through her that before she knew it, she was crying but she really didn't know why. It was one of the best feelings she had ever felt, but it was also so overwhelming and overstimulating that she just had to cry. She couldn't keep it in as she felt Momo helping her ride out her orgasm.

It probably took close to fifteen minutes for her to even realize where she was again and what was happening. Kira realized that she was under Momo’s comforter and that Momo was holding her while stroking her hair.

As soon as she opened her eyes, Momo was kissing her forehead gently. “Are you okay, sweetheart?” Sweetheart? Kira liked that. It made her chest feel warm.

Kira slowly nodded, “Y..Yeah. T..That was incredible. Holy fuck. I've never felt anything like that b..before.”

A yawn then involuntarily ripped through her and she pouted when Momo giggled softly. “We've got about an hour or so before curfew. Why don't we get a nap together?”

Kira almost agreed to that immediately. She was spent and it honestly felt like she could sleep for a whole twenty-four hours, but she also knew that Momo hadn't gotten the chance to get off yet and Kira wasn't a quitter. “Nu uh. Your turn, if you want me to touch you that is.”

She could see Momo’s eyes darken and her cheeks flush. “K..Kira.. don't feel like you have to just because you came. Seeing you like that was enough for me. I'm going to remember the way you looked as you screamed out for me for the rest of my life.”

Kira reached out and stroked a thumb along Momo’s jaw. “I want to, Momo. I don't feel obligated, I want to.”

Momo nodded, “O..Okay, Kira.”

They maneuvered so Momo was on her back and Kira was laying beside her. She was honestly out of her depth, she hadn't really touched a woman before but she was going to do her best. Momo deserved that, and Kira had always been a fast learner.

She trailed her fingers up and under Momo’s sleep tank top, but as soon as Kira let her fingers touch the skin of Momo's stomach, she noticed her girlfriend squeeze her eyes shut and go rigid. “Momo..baby.. do you want me to stop?”

Momo shook her head without opening her eyes. “I..I’m just very self conscious about my stomach, and my body and general. I've gotten bigger than I wanted and I haven't been able to get back to a place where I'm comfortable with myself yet. I don't want you to think I'm gross and don't take care of myself.”

Kira withdrew her hand and slid up to gently cup Momo’s cheek. “Momo, hey.” Momo finally opened her eyes and they were immediately watery. “You can take those thoughts, kill em and bury em because nothing could be further from the truth. Do you have any idea how much I respect you for how hard you work? Do you have any idea how beautiful I find not only your body, but your mind as well?”

Momo sniffled and slightly shook her head. Kira traced gently along her cheek, wiping away a stray tear. “I know you work hard. I know how fucking incredible you are. You are one of the most hard working people in this school. I find that so fucking attractive. You're so smart too and I also find that attractive as well. There are so many things about you I find attractive. Your body is also one of them. I don't stare a lot because I don't want to come off like a creep but Momo, you have no idea how hard it is not to stare. Your body is so fucking sexy.”

Kira dipped to kiss along Momo’s collarbone. She was rewarded with a little giggle and a slight inhale. She then moved to kiss Momo’s slightly exposed sternum before finally moving down and lightly grabbing the hem of Momo’s tank top. “Can I? You have every right to say no. You tell me no and I'll stop.”

They held eye contact for a moment before Momo nodded. “You can.”

Kira made sure by the look in Momo’s face that she was truly okay before lifting up Momo’s tank and pressing kisses to the soft skin of her stomach. She whispered loud enough for Momo to hear. “Absolutely beautiful.”

Kira didn't know how to explain to Momo that she was her absolute perfect body type. She truly found Momo to be one of the most beautiful women she had ever seen. Her girlfriend was soft in all the most beautiful places and Kira loved it. She wanted to place gentle kisses along her wonderful tummy, she wanted to leave bite marks and bruises along her incredible thighs, and she wanted Momo to eventually sit on her face. Momo’s weight wasn't a fetish to her, her girlfriend was genuinely just so goddamn beautiful and attractive to Kira. Kira wanted to shout to the whole world and gesture towards Momo as if to say, “Look at this beautiful goddess of a woman I get to be with.”

Kira pressed some more kisses around Momo’s navel. “You're an absolute goddess of a woman, Mo.”

Kira felt hands thread through her hair as she heard Momo sharply inhale before whimpering out her name. “K..Kiraaa..I'm already so close..I've been worked up all day..p..please..”

Kira followed her instincts and slid between Momo's legs, pressing a kiss to Momo’s still clothed pussy lips. In that kiss alone, she could feel how soaked Momo’s leggings and panties were. She waited until Momo was looking at her through half lidded eyes, and panting so hard Kira could see the quick rise and fall of her chest. She flattened her tongue against Momo’s covered lips and licked a long stripe up, maintaining eye contact the entire time.

Just the little bit of taste Kira had on her tongue was enough. She was going to be addicted for life. She smirked as she watched Momo’s eyes blow wide. “I can't wait to finally get a real taste of you.”

She shimmied up and slid her hand down Momo’s leggings, she wanted to try to eat Momo out, but she also didn't want to push things too far too fast. Kira quickly found out that Momo truly had soaked through her panties and leggings. She wasn't even in Momo yet and her fingers were coated. “You still okay?”

Momo hastily nodded. “Yes. Please touch me K..Kira.”

Kira felt her way around until she pressed into what she presumed was the right spot with her index finger, and by the way Momo inhaled and moaned, she was on the right track. She soon added a second finger just like Momo had done with her and slowly started to pump her fingers. “J..Just like that, Kira. I'm already so c..close. Touch my c..clit, pleaseee.”

Kira continued to pump her fingers and blindly felt around for Momo’s clit with her thumb. It took a moment but the moan Momo let out when she thumbed across a sensitive bud told Kira she had found the right spot.

It was only a minute later when Kira felt Momo grip onto her arm and harshly squeeze. “Right there, sweetheart! I'm going to cum! I'm going to..Kira!”

She could feel Momo tighten around her fingers but she also knew enough that she wanted to help Momo ride this out, so she continued to pump her fingers until Momo whined and blindly pushed her hand away.

Kira would never forget the look on Momo's face as she came, or the sounds she made. It was incredible. It truly was.

Kira was about to slide up so she could cuddle Momo but that's when she realized her hand was still soaked. “S..Sorry, I'll grab you a towel or y..you can wipe it on the blanket.”

Kira looked up to see Momo staring at her with half lidded eyes. Kira smirked, “What are you apologizing for?”

She stuck her soaked digits in her mouth and sucked them clean as she could hear Momo whimper. “K..Kira.. O..Oh my..”

Just like Kira had guessed, she loved the way Momo tasted and she was very much going to be addicted to the taste of her.

She made a show of licking her fingers clean before sliding up and pulling Momo close to her as they both slid under the blanket again.

Kira felt her eyes immediately start to droop when she finally settled and let her body relax. Momo softly spoke to her but it sounded like she was on the verge of sleep too. “You're beautiful, Kira.”

Kira contently sighed into Momo's neck. “You’re beautiful too, Momo. You always have been.” Her body felt so heavy all of a sudden. “Can I just crash here?”

Momo let out a sleepy laugh, “I'm not one to usually break rules, but I really want you to stay with me. Just don't tell Iida.”

Kira snorted, “No problems with that h..here.” She could barely keep her eyes open and her speech was slurred, but as she heard Momo’s breaths even out, she quickly fell asleep too.

Chapter 7: Riot girl

Notes:

I hope everyone enjoys the chapter! Every time I write about Transfem Katsuki, I always think of the song Riot Girl by Good Charlotte. Like that just fits her.

Stay gay my friends

Kira woke up early the next morning for her run by just pure muscle memory, she didn't even have her phone with her. She had barely even moved when arms wrapped around her waist and she heard Momo whine. “Nooo. Kiraaa, it's too earlyyyy.”

Kira laughed softly as she let herself be pulled into Momo’s embrace. “Baby, I have to get my morning run or it'll throw off my whole day, plus we actually all have class today so I have to get out of here before class prez is up and running around.”

She could see Momo start pouting, which was so fucking cute it should be classified as illegal. “At least give me ten more minutes, please? With our schedules, we probably won't get to really spend time with each other until tomorrow evening.”

Kira couldn't be upset with that. She really couldn't. Plus, she really did want to just stay in bed with Momo but she also had to keep somewhat of a daily schedule or it would completely throw her day off kilter. She settled back down, this time on top of Momo, and buried her face into her girlfriend’s neck as she felt arms wrap around her. “Alright. Ten minutes, baby.”

She could feel herself getting comfortable and drifting back off to sleep almost instantly which was odd for her, must have been because she actively wanted to stay with Momo, so she decided to cause mischief to keep herself awake instead. She nuzzled her nose along Momo’s neck, giving light kisses until she sank her teeth into the spot between Momo’s neck and shoulder.

Kira smirked against Momo's neck before licking and sucking on the mark, turning it into a hickey. The whole time Momo’s whines and whimpers spurred her on. “K..Kira..not f..fair.” Kira smirked to herself as she felt Momo’s hand travel up into her hair and pull slightly.

She felt proud when she finally leaned away to get a nice view of the already bruising skin. She also knew her own neck was covered in them from the night before so it was fair play.

She felt proud for about five more seconds before she felt the hand that had made its way into her hair tighten. She then had to bite her lip to keep from moaning as Momo yanked at her hair. Kira then proceeded to squeal as Momo flipped their positions.

Kira had just learned something new about herself, she really liked to have her hair pulled apparently.

Momo instantly had her arms pinned above her at the wrists and was trying her best to glare down at her, but Kira could see the grin trying to fight its way to the surface. “What do you think you're doing, sweetheart?”

Kira felt her previous smirk vanish completely. The mix of Momo physically tossing her around, the hair pulling, and the raspy nature of Momo's sleepy voice immediately made her bite her lip again to keep from releasing the most needy sounds.

She could immediately tell that Momo knew what effect she was having on her. Her girlfriend grinned and it was feral and it was making Kira feel things she had never felt before. She wanted Momo to hold her down and fuck her until she couldn't remember her own name. She wanted Momo to ravage her. Lap her up all the way to the bone.

Momo leaned down and brushed their lips together for just a second and wouldn't let Kira chase after when they separated.

Momo proceeded to growl in her ear and it made Kira ache with need. “That was dirty. If you wanted to mark me, all you had to do was ask, sweetheart. Keep stuff like that up and see what happens. Don't be a n..naughty sl..slut..”

Kira whined outright at Momo’s words. The words were slightly stuttered, probably from being nervous but they still had an effect. Slut. She liked being called that, huh?

Kira tried to lift her hips to get some kind of contact. “I w..want you to put a baby in me, Momo.” Kira’s eyes went wide when she registered what she had just said. W..What the fuck was that?

Not to even mention the fact that that wasn't physically possible for the two of them right now, It just came rolling out of her mouth in the first place. It just felt instinctual. It honestly felt like a need but she was not ready to look at that feeling right now. She felt her face heat up and she was so embarrassed she wanted to die, but it only seemed to make Momo’s eyes darken.

Her girlfriend kissed and nipped up her jaw while still holding her wrists. Momo then began to slowly grind against her crotch before switching their positions again. Kira ended up on her knees with her chest pressed into the mattress.

Kira felt Momo rock into her from behind as a hand threaded through her hair just for her to hiss and then whimper when Momo yanked on her hair, pulling her head up and back towards her girlfriend. “Don't be embarrassed, sweetheart. I'd love to put a baby in you.” Her voice was so sultry and it was driving Kira insane.

Confident Momo was a goddess among mortals and Kira would stand by that until she died.. Again.

Kira did in fact not get a run in that morning, but she still got plenty of cardio in for the day by the time she left Momo’s room to get a shower and dressed for the day.

It was a couple hours later and Kira was walking into home room, she’d still never get over how great she felt in the girl's uniform. It made her wonder what would have happened if this quirk accident happened a couple years earlier. Would she have felt even remotely safe enough to find herself? Probably not if she was being honest.

Kira was usually first to class but she could also hear Mina and Kyouka coming down the hall behind her and that was unusual. They were usually in class like ten or fifteen minutes before class started at most, not thirty.

Kira didn't like it. It felt like trouble and as she was taking her seat, she heard Mina's high pitched squeal. “Look at your neck! I knew I saw you and Momo kissing outside of her room this morning. Girlypop, I want details!”

Kira instinctively tried to cover her neck. She had thought she covered the marks up pretty well.

Jirou snorted. “Saw them? I heard them last night. I had to leave my room the first time I heard Momo’s name get moaned out, but apparently that wasn't long enough because as I was coming back, I heard Momo screaming from down the hall and I had to turn around and go back downstairs.”

Kira felt her face flush hot. “Both of you shut the f..fuck up. Did anyone else hear or see anything? I don't care that people know we're dating but I don't want people being perverts either. I mean Todoroki and Shinsou already caught us making out yesterday, that was bad enough.”

Kyouka shook her head. “Most of the class was already downstairs last night and Shouji was out late on patrol. He'd be the only other one who sometimes hears stuff even if he tries not to.”

Kira sighed, that was a relief. She didn't feel like explaining to the entire class why Momo had been moaning out Kira and not Katsuki. That and she just didn't feel like talking about her sex life with people she wasn't close to.

She checked the door and she couldn't see or really hear anyone coming. “Can you two fuckers keep a secret?” Kira knew they could but she was going to make sure anyway.

They both nodded, and Mina seemed to pick up on the seriousness of the situation. “Of course Kat, you know that.”

Kira sighed as she leaned against her desk. “I'm a girl. Not just like physically and shit right now, but like mentally and emotionally and shit too. I'm trans and whatever. My name's Kira. The two of you, Momo, and Eijirou are the only ones that know. I'll probably tell Izuku too but I haven't had the chance yet.”

Mina softly smiled at her. “I'm proud of you, girlypop.”

Kyouka also grinned at her. “Kira’s a really pretty name.”

Kira was relieved at their casual acceptance, but just like Eijirou, they were taking this well. Too well. “Did you both already know or something?”

Mina giggled. “Kira, other than Eijirou and Midoriya, Kyo and I are the two other people you've spent a massive amount of time with the last couple of years. When you're not tense and you finally let yourself relax, the real you comes out. Your vibes have never really screamed bi guy, more like just one of the girls. Sure, you could have just been a more feminine guy but I just never got those vibes.”

Kyouka nodded. “Basically what Mina said. You've always given off badass big sister vibes more than protective big brother. When you got hit with this quirk, it just kind of became apparent, at least to us anyway. I could tell you were freaking out, but I don't know, there seemed to be a sense of longing for acceptance. We're your friends, Kira. We pay attention just like you do.”

Them having their guesses just like Eijirou did made her feel embarrassed, relieved, confused, and all sappy all at one time. Plus if they knew, there was a good chance Izuku knew. Did anyone else know though? “Do you think anyone feels this way?”

Mina shook her head, “I don't think so. Midoriya probably does cause you two grew up together and you two are like history books for each other, but I doubt anyone else does. Maybe ‘Raka because you two have spent quite a bit of time together over the last year, but other than her, I doubt it. You've expanded since our first year but you've always kept your core circle pretty tight knit.”

That made Kira sigh a little in relief. Mina was probably right about that. She had become friendlier over the years but her close group of friends stayed basically the same.

That's when Kira noticed Mina’s fond smile turn mischievous. “Nowww about you and Yaomomo. I. Want. Details. Girl.”

Kyouka smirked and nodded. “Spill everything. Momo looked like she was absolutely glowing this morning when she was making her morning tea. She was all happy and giddy as she hummed through the kitchen. She's usually in a good mood in the mornings, but never that good of a mood.”

Kira felt herself flush. “It may have been one of the best nights of my life.” She went over most of what happened with them yesterday, skipping some of the more embarrassing and intimate details until she heard other students approaching.

Kira watched as Izuku, Todoroki, Tsuyu, Iida, Kaminari, Eijirou and Momo all walked in as a group. She could feel a smile make its way to her face when she spotted her girlfriend.

Momo smiled and walked over to her. She could tell by the taller girl's walk that Momo was feeling confident. Momo approached her. “Hi sweetheart.”

Kira felt her face flush once more. “Hi Mo.”

She watched as Momo reached out towards her and tucked a strand of her hair behind her ear.

Kira heard a dramatic gasp come from her right. “You two are dating!?” She rolled her eyes at Kaminari’s voice. She rolled them even harder at his next question. “Does this mean I'll finally have a chance with you, Jirou?”

Kira had to suppress a snort as Mina giggled and Kyouka rolled her eyes. Mina and Kyouka weren't official as far as Kira knew but everyone knew those two were bound to get together eventually.

Kyouka gestured for Mina and their pink skinned friend ran over to her with a squeal, throwing her arms around the shorter woman. “Our blastybabe and Momo weren't the only ones who made things official yesterday. I took Mina out before we both had work and I asked her to be my girlfriend.”

Kira grinned as she happily stood corrected. The two of them were official.

Sero piped up from his position by the door, him and a few others had just entered the class. “Isn't it crazy that the only five official couples in our class are queer couples? Plus Shinsou is with Monoma. It's beautiful honestly, we may really be the gayest class to ever grace this campus. Keep it up, guys.”

Kira had to suppress another snort. She wanted to snark something about that being funny coming from an out bi guy who thirsted after Todoroki for over a year and who was openly thirsting after Iida now. But, Sero was chill so she wouldn't throw him under the bus like that.

See? She could be plenty nice.

“Aren't Bakugou and Yaoyorozu a straight couple though?” The question came from a dejected but honestly confused sounding Kaminari. It hurt, but Kira couldn't be mad. None of them knew who she was now.

She wanted to tell them. She wanted to tell everyone and just rip the bandaid off. Most of them would understand. None of them would care if she was a girl, but she just couldn't force herself to say anything. There were too many uncertainties and that scared the piss out of her.

Kira just watched Sero shrug. The tall boy looked towards her out of the corner of his eye and gave her the subtlest little nod. “I don't know man, they're still a bi for bi relationship, so it sounds queer enough to me.” Fucking hell, did Sero know too? She knew he was more receptive than the “mindless stoner” title he had been awarded ín their second year. The sneaky little accepting shithead.

Luckily Aizawa entering the room gave her enough of a distraction for the discussion to shift to something else.

Momo gave her hand a squeeze before the taller girl made her way over to Iida to probably talk about their last upcoming representative meeting. Kira turned her attention to Eijirou who was smirking at her. She shoved at his stupid hair but he easily dodged and that's when she noticed Izuku had made his way over next to them. “Kacchan?”

Kira looked at him, there was a bright smile playing on his face and his eyes were sparkling like they always did when he was insanely happy about something. “Yeah, Izuku?”

The skin around his eyes crinkled from him smiling even wider, “I'm really happy for you.”

Kira couldn't help but grin as she shoved at Eijirou again. She could tell Izuku was saying he was happy for her and Momo, but she could also tell he was saying something else. This was Izuku after all. He knew. He'd probably always known and he accepted her. She didn't need to tell him she was a girl and he didn't need to tell her he knew. They both just understood. “Thanks, Izuku.”

Chapter 8: 48 hours early

Notes:

I hope everyone enjoys the new chapter!

Stay gay my friends

It was reaching the end of day five of this quirk and Kira was trying to not let it get to her. In less than forty-eight hours, she'd have to go back to being “Katsuki” and pretending to be a guy and she just didn't think she could do it.

The thought of having to have that body again and to deal with everything now that she knew the truth about herself and she was finally fucking happy, it was depressing.

She had talked to Eijirou and Momo about how she felt, and they tried to help the best they could. Eijirou finally got information back from his momma and she had given him the information of her doctor to give to Kira. The doctor was still in practice and Eijirou’s momma said he should easily be able to see her. Which did help her feel better. At least there was some light at the end of the tunnel. Hopefully she wouldn't have to deal with pretending to be Katsuki for too long.

Momo also told her she was going to treat her extra softly and intimately the next couple of days and Kira was excited to get to be cuddled up with her girlfriend tonight, even if she had to endure a class movie night.

Kira was humming to herself as she got ready to go downstairs for the movie night. She was wearing a light pink soft and silk pair of pajama shorts that she had bought herself after patrol one evening, and she was currently slipping on one of Eijirou's massive and worn out Crimson Riot hoodies that she had stolen when they dated a long time ago.

She smirked as she looked in the mirror, she felt so fucking cute. She really hoped she could continue to feel this way even when the quirk wore off. She wasn't going to think about that tonight though. Tonight she was going to go downstairs and cuddle with her girlfriend on the couch, hang out with her friends, and eat shitty junk food. That was what she was going to do tonight.

Kira grabbed her phone and slid it into her hoodie pocket as she made her way out the door, hearing it shut behind her.

As she made her way to the elevator, she got a message from Aizawa. “You know if you ever want to tell Hizashi or me anything, you can. You're our kid. And remember to tell the others not to stay up too late tonight. It's still a school night. Have a good night and keep them all in line, golden child.”

Kira stopped in her tracks. It always made her feel so weird when Aizawa said stuff like that. Neither of them were super good with emotions. He was a great dad, but neither of them really talked about it all that much.

Plus that sounded very much like Aizawa and Yamada both probably had some idea of who she really was. Which made sense honestly, they were her dads. She had been under their legal care for a while now. Plus she didn't have to worry about them not being accepting or anything.

Golden child. Aizawa had always called her the golden boy, but he had called her the golden child. He definitely knew, or at least had a guess probably.

Kira typed out a quick message and shoved her phone back in her pocket, and the thing was, she wasn't nervous at all when sending it. “I'm a girl. My name's Kira.” She pulled her phone back out and sent another quick message as she felt her cheeks heat up just a little. “Thanks, dad.”

She made her way down and immediately went towards the kitchen where Momo said she would be. Kira smiled when she found Momo making herself some tea.

Kira wrapped her arms around the taller girl from behind, letting her arms rest on Momo's stomach. Momo giggled, “Hi sweetheart.”

Momo twisted so they could hug and Kira leaned up for a kiss. “Hi baby.”

She never thought she would like pda or pet names, and she still wasn't the biggest fan of either thing but it just felt right with Momo. Plus the only other person she had seen in the kitchen was Shouji and she knew he wouldn't say anything to anyone. He was respectful like that.

She should have known she wasn't that lucky. Kira heard a very familiar squeal from the one and only pink demon in her life. “Oh. My. Gods. You two are so cute!”

Kira turned just slightly to see Mina jumping up and down and Kyouka smirking as she waved a phone. Kira lightly growled. “Let me see the picture I know you just took.”

Kyouka tossed her the phone and Kira looked through the recent photos. Her and Momo were actually really cute. She knew Momo was adorable, but it was weird seeing herself like this. She was smiling softly at Momo. They looked happy. Kira looked happy, because she was. There weren't many pictures of her that existed where she looked genuinely happy.

Kira smiled as she tossed the phone back to Kyouka. “Send me those, will ya? They're super cute.”

Kyouka gave her a fond looking smile in return. “You know I will. I'll send em to both of ya.”

Kira felt her phone vibrate in her pocket and she knew Kyo sent her the pictures. She was definitely making one of them her new lock screen for her phone.

Thirty minutes later found Kira happily snuggled up next to Momo when she started feeling incredibly nauseous all of a sudden. She leaned her head against Momo’s shoulder and whispered to her girlfriend. “Mo..I really don't feel good. Can you help me upstairs?”

Both of them knew that if Kira was actually asking for help, then she really didn't feel good. She could see Momo give her a concerned look. “Of course sweetheart. Do you need me to make you anything?”

Kira shook her head. She just wanted to lay down. She had no idea why she felt bad and why it came out of nowhere and her head and body were starting to hurt too. It felt just like when that girl touched her with her quirk..

There was no way! She was supposed to have two more days! She couldn't change back now. “M..Momo.. I think it's the quirk. I need to get out of here.”

She didn't want the quirk to wear off with others around. She didn't want to have to explain to everyone when she was probably going to end up in tears when she changed back.

Momo tossed the blanket off of them but as Kira stood, she felt that familiar tug in her stomach and she felt like doubling over. It hurt so bad that she closed her eyes and when she opened them, she could immediately feel the tears making their way to her eyes.

She just felt wrong. Her body felt wrong. The comforting weight she had grown to love was gone from her chest. She slowly reached up with a trembling hand and found her hair was back to being short. Everything just felt wrong.

Kira heard Momo softly whisper to her. “Sweetheart, let's go to your room. Come on.”

There was a chance she could have made it to her room without crying, there was a great chance she could have, but then Kaminari had to open his mouth. “There's the ole beast again. Ya know Kacchan, I'm going to miss seeing how pretty you were.”

Maybe on any other day, she wouldn't have cared about that comment because she knew there wasn't any real malice behind it. Maybe on another day, she would have been fine and just told him to fuck off, but today wasn't one of those days because she started to just uncontrollably sob. “I..It wasn't supposed to b..be today. I was supposed to have two more d..days!”

She didn't care about anything else as she buried her face into Momo’s neck. Momo gently shushed her. “Kira. My Kira, it'll be okay. W..We'll get this figured out.”

Kira whimpered softly. “I..It’s not f..fair. I just found myself and now everything is just gone.”

“Uhh what's happening? Why is Bakugou crying? Is this like a hormonal thing?”

Kira heard a smack and she heard Mineta yelp from pain. She felt Momo tap her thighs, and under any normal circumstance, she wouldn't have done what she did next with such a big audience but she just didn't fucking care right now. Kira jumped enough to wrap her legs around Momo's waist and let the taller girl carry her towards the elevator.

Neither of them spoke until the elevator doors shut and Kira was standing on her feet again but they were still in an embrace. “I'm so sorry, Kira. I'm so sorry, but I need you to know that nothing changes. You are still who you are. You are still Kira and I still love you. With Eijirou’s help, I did a lot of digging and I found that girl who activated her quirk on you. I found her and her mother. I haven't made contact of course, but I was thinking that maybe we can try talking to them and seeing if she'll let her daughter activate her quirk on you again. At least it'll give you a little more time until we can figure everything out with your doctor.”

Kira looked up at her girlfriend. “You two did that for me?”

Momo smiled at her and ran a hand through her hair. “Of course, sweetheart. I'd do anything for you.”

Kira leaned in and kissed her. “I love you.”

She heard Momo lightly gasp before she was kissed again. “K..Kira..I love you too.”

Maybe they were moving too fast for some people, but everything felt right. Kira knew she loved Momo just like she knew she was a woman. She knew how she felt and she knew who she loved.

She felt Momo gently thread a hand through her hair and Kira tucked her face into Momo’s neck, mumbling into her skin. “M’sorry you have to deal with this awful body now too. I'll understand if..”

“Kira, stop. Please sweetheart.” Kira bit her lip to try to keep from crying as Momo continued while wrapping her arms around her in a protective manner. “You are my girlfriend. I love you. Your body doesn't change those things. Remember, I liked you before any of us knew who you really were. I was attracted to your fire and determination. Your intelligence and your wit. I also found your body attractive before this quirk incident. I like you for you. I love you for you. I know this must all be extremely painful and disorienting, but please don't think it changes how I feel about you at all. Okay, love?”

Kira nodded against Momo’s neck. She believed Momo, she really did. “Okay, Momo.”

Happy pride and stay gay my friends

“Katsuki Bakugou liked being a girl.”

That was all Kira had heard for the last week. She heard in direct statements, whispered questions from people who thought she couldn't hear, and from messages and rumors.

It was irritating.

It had been exactly seven days since the quirk wore off and she had to go back to being “Katsuki” but she couldn't even do that because people kept fucking with her.

After her little freakout in the common room, most of her class knew that she at least liked being a girl. They may not know the specifics but most of them could put it together, but someone had said something to someone out of class, and well they may be inspiring heroes, they were all still third year students and it didn't take long for word to spread.

Kira cared less than she thought she would. Maybe it was because people didn't fully know what was happening, or maybe she truly didn't give two fucks about the people who weren't in her inner circles, it was just irritating more than intimidating. People kept whispering, staring, and pointing and it was just obnoxious. Like fuck, leave her be.

Today was going to be a good day though. Her, Momo, and Eijirou were on the way to meet with the girl who had activated her quirk and her parents to see what they could work out, plus Kira had an appointment with the doctor Eijirou had told her about.

It was over six months from today but progress was progress.

Kira wore a simple pair of high waisted black jeans and one of Momo's jackets that covered a worn out band shirt. It wasn't anything overly feminine but it made her feel a little better.

The three of them walked into the restaurant they all had agreed to meet at, and Kira scanned for the girl. As soon as she saw her, the little girl waved. “Dynamite!”

Kira waved back as the three of them made their way over. They all exchanged welcomes as the three of them sat down. The little girl's father introduced them. “We haven't really been able to meet, We're Mr. Nakamura and Mrs. Nakamura, and this is our daughter, Kimi. We're still incredibly sorry that you had a mishap with our daughter's quirk. She's only had it for about a year so sometimes when she gets scared she accidentally activates it.”

Kira politely shook her head. “There's no need to apologize, accidents happen.”

Mrs. Nakamura smiled. “You're such a lovely young man. We talked on the phone to a young lady named Yaoyorozu. She asked if it was possible to meet. Are you having some lasting side effects? We'll answer any questions we can.”

Kira tried not to physically recoil from being called a guy. It's not like these people knew. She glanced over at Momo and let her start the conversation. Kira still wasn't really a people person so to speak. “I'm Momo Yaoyorozu. I called you because..because we were wondering if your daughter would be able to activate her quirk again?”

Mrs. Nakamura looked genuinely confused. “Why would she need to do that?”

Kira picked at her painted nails out of nervousness and just figured she'd get right to the point. “While I was changed during that week, I figured out a lot about myself. I figured out that I'm not a guy. I'm a woman. I'm meant to be a woman. I have an appointment set up to permanently transition me but it's over six months away. I..I was just curious to see if I could feel like myself again. Even if it's just for one more week.”

There was a silence that settled over the table and Kira immediately started to fidget as her brain went into overtime. ‘Oh fuck, they're going to think I'm a freak. They're going to tell people I came to them with a fucked up request. We gotta get out of here.’

Kira went to stand, “Forget we were even he..”

Mr. Nakamura held his hand up gently. “There's no need to freak out, I promise.”

Kira sat down and mumbled. “I'm not freaking out.” She was. She really was.

Mrs. Nakamura smiled at her. “I won't lie, it is a little surprising but that's basing who you are only on news coverage and that's not how we should do things and we aren't the type of people to judge. Plus I can definitely see how our daughter’s quirk would ease the pain of everything you're feeling now. I have no issues with it, as long as my husband and Kimi agree as well.”

Mr. Nakamura nodded. “I'm fine with it as well, it's always nice to help someone feel like themselves. What do you think, Kimi?”

Kimi looked up at her. “You mean you like being a girl? You're not mad about my quirk?”

Kira smiled softly. “I do like being a girl. I am a girl, and I'm not mad about what happened with your quirk. Even if I didn't like being a girl, I wouldn't be upset with you. Accidents happen all the time.”

Kimi grinned with a wide smile. “Okay! I'll help you, Lady Dynamite.” Kimi giggled and Kira couldn't help but like the sound of Lady Dynamite.

Kira smirked, “I may have to steal that name from you, kid. Lady Dynamite is a pretty cool name.”

After a little bit more discussion Kira held out her hand and was ready for Kimi to activate her quirk. Mr. Nakamura gave her a look, “Now be prepared, this may not work.”

Kira scrunched up her eyebrows, “Why wouldn't it?”

He gave her a soft look, “So far what we've been able to tell, our daughter’s quirk works by changing someone to the opposite gender physically. You've figured out that you're a young lady, so the quirk may not work or just give you the same body you have now. It may even do something in between because there are all kinds of possibilities out there.”

That actually made a lot of sense. Kira really wanted a body to match the way she felt, but if the quirk gave her a body like she had now because she was truly a woman, it would suck on one hand but it would also be kind of euphoric to be validated that she really was a woman. It would be bittersweet either way.

Kira nodded, “Let's give it a shot.”

Kira watched as a silver glow emitted from Kimi’s hand and felt her lightly touch her hand. The feeling was immediate and she braced for the pain, shutting her eyes and waiting for it to stop. Once it did, she knew immediately that her body hadn't changed. She still felt like she was a spectator watching a husk walk around.

It was painful not to have the body she wanted, the body she needed, but she also felt somewhat peaceful because she had been validated in her feelings. She was a woman and there was no room for arguments.

Mrs. Nakamura gave her a sad smile when she opened her eyes. “Sorry, honey.”

Kira shook her head. “No need to apologize. It sucks that I'll have to wait, but it feels validating in a way that the quirk gave me a man's body. I am a woman and it's nice to have that validation.”

Kira felt Momo give her thigh a gentle squeeze, and she looked over at her girlfriend with a small but genuine smile. “We'll get it figured out.”

-

Momo sat on the couch for class A’s final movie night together in the dorms. They all graduated tomorrow morning, so they all agreed to spend the night together and watch movies. Most of them promised they would all try to keep in touch after graduating, but Momo knew life had its own way of working so she was excited for this night.

Kyouka was on her left and there was a corner spot open on her right that she was reserving for Kira.

Momo heard Mina chime in from next to Kyouka, “Yaomomo? Where's Kira? She's the only one missing and we can't start this night without her.”

Momo was about to respond when someone else responded for her. “Don't get your leopard print panties in a twist. I'm right here.”

Momo smiled over her shoulder as Kira strolled into the room and flopped into the spot next to her, immediately pulling her into a simple kiss before nonchalantly leaning into her side.

Mina stuck her tongue out at her girlfriend. “Like we don't have the same pair of leopard print panties. We bought them together, blondey.”

She couldn't help but grin as she threw an arm around Kira’s shoulders and held her close as Kira and Mina playfully bickered. Momo loved how comfortable and confident the blonde had gotten over the last seven months. It took Kira a while, but she eventually hit her stride, especially when she had her appointment and she was able to permanently transition. That had been three weeks ago and Momo hadn't seen the smile fall off Kira’s face since then.

They both were in good places. Kira felt like her authentic self and Momo had finally gotten back to a place where she loved her body again. She still had curves, a muffin top, and love handles, and her thighs were still soft and her rear end was still plump, but she was in a spot that felt good. She was at her ideal body image now and it made her feel confident in herself again and that's what mattered.

Plus it was always nice when she caught Kira staring at her when she worked out or was bent over doing something. She always felt ruby eyes trained on her and it made her squirm in the best of ways.

Her thoughts drifted to the first time Kira had told her to fully sit on her face. Momo had been nervous at the time because of her weight but Kira grabbed her legs and forced her entire weight down on her. That had been one of Momo's most intense orgasms of her life and Kira told her to never hold back on her, that she could handle a “goddess” sitting on her and if she couldn't then she deserved to suffocate.

Momo felt her face slightly blush at her thoughts but as she quickly looked around, it seemed everyone was still engrossed in their own conversations, everyone but Kira.

Kira smirked at her and shifted them so Momo ended up on Kira’s lap. Momo felt her face heat up even further as Kira whispered in her ear. “I can't wait until this movie is over so I can take you upstairs and make sure this whole goddamn building hears your screams. I know by that little blush that you're thinking of me fucking you senseless.”

Momo bit her lip and tried to weakly and quietly reprimand her girlfriend. “K..Kira..such vulgarity.”

Kira grinned at her. “You don't seem to complain about it any other time.”

Momo couldn't help but hide her face into Kira’s neck. They'd battle for dominance later, but for right now, she was content to let her girlfriend possessively hold her waist and whisper dirty and naughty things into her ear while she tried to focus on the night with their friends.

Well..until about halfway through the movie that is. When everyone was engrossed in the movie, Momo let her hands travel under the blanket she had brought down and into Kira's pajama bottoms and panties.

She smirked as she heard a sharp intake of breath and watched as Kira dug her fingers into the arm of the couch. Momo teased Kira for about ten minutes before she heard a quiet “fuck it” be murmured in her ear. That's when her hand was being removed and she was being lifted into the air bridal style and Kira was carrying her towards the stairs.

“K..Kira!”

Momo heard Kaminari chime in from behind her. “Wait, where are you two going? The movie isn't over yet.”

Kira barked out a laugh as they went up the stairs. “Use your imagination, pervert, and turn up the volume. Or don't, I honestly don't give a shit.”

There were giggles and she could hear Kyouka chuckle. "Horny damn bitches."

Momo buried her face into Kira's neck until they got to her room. She then squealed with laughter as she was tossed on the bed and Kira was immediately on top of her and kissing her neck. “You're going to fucking pay for that shit, brat.”

Momo moaned before grabbing a handful of Kira’s hair and pulling, making Kira moan as well. Momo couldn't help but smirk, “I’d like to see you make me, Lady Dynamite.”

Kira gave her a lustful but feral grin. “Oh, I'm going to, princess.”

Hours later, Momo had Kira tucked into her side as they were both fast asleep, and even in her dreams, Momo wished for her and Kira to have many, many more lovely nights like this one to come their way in the future.
