Fuyumi was confused. She had been confused ever since she got a message from her littlest brother Shoko, err, Shoto - why did she keep thinking that his name was Shoko? That sounded like a girl's name - asking her to go shopping with him. Apparently he was also bringing some friends along too. It was so completely out of the blue that Fuyumi didn't know what to say.

But she was going to be a good big sister and help her little brother out with shopping. Maybe he found a girl he wanted to impress? That was actually kind of adorable, but she kind of thought her brother wasn't into girls, or men, her brother gave off some strong asexual vibes from time to time. Like that time Fuyumi's girlfriend Moe walked around topless to try and tease him.

It didn't work, Shoko, err, Shoto, didn't even blink, and all the act did was make Fuyumi herself that much more hot and bothered. Not that Moe needed to know anything about that. Seriously, why was she just so, so, so.

Gay! Seriously! She blamed her father on this! Seeing a large, muscular macho man all day made her want something softer so now she was probably the gayest lowkey gay she could possibly be. Not that she checked out every girl she saw when she was out in public like Moe did, she did have standards.

Like the group walking towards her. A striking sporty looking girl with red hair, dressed in a casual T-shirt. She was noticeably busty, but she was also the least busty of the group. Wearing a tank top that was somehow tight around both her gigantic breasts and slender stomach was a blue haired girl, that was bouncing around like it was nothing, she looked just kind of super cute. Then there was the shortest of the three, a girl with hair like her little brother's, half white and half red. She even had his eyes. Not the tits though. Those breasts and that dainty figure were far too girly to ever belong to her little brother.

And then there was the one red and one white fox ear poking out from the girl's head and a swaying fox tail.

Seriously, why were all of these girls so busty? It just didn't seem fair. Like they made Fuyumi feel flat. And she was not flat. While she wasn't as large as Moe was - Moe might be able to compete with the red head actually - she had a respectable pair. And why did she have boobs on the brain? Oh, right, because the three walking towards her had more boobs between them than her graduating class did.

And why were they walking towards her? And why was the short busty version of her brother smiling at her?

"Fuyumi," the fox girl said with a soft smile on her face. Come to think of it, they were just about the same height weren't they. More evidence that this wasn't Shoko, er Shoto. Really what was with that name. "Thanks for coming. I know it came out of the blue, but I really don't know anything about being a girl, and while Itsuka, Nejire, and, Momo have been a big help, I wanted your advice too."

"Uhh," Fuyumi blinked and stared at the girl for a few seconds.

"Oh, right, this is Nejire hado, she's an upperclassman, and this is Itsuka Kendo, she's strong, really strong. And pretty. I think they're my girlfriends." The girl looked back towards Itsuka who gave a half shrug, while Nejire nodded eagerly. "They're going to go shopping with us today, is that okay?"

"Uhh?"

Itsuka, clearly the only person in the group that was sane, took a step forward, slightly pushing the red and white haired girl back. "Uhh, Shoko, you did tell your sister what happened right?"

Fuyumi shook her head at that accusation. "Wait, so, let me get this straight. This beautiful fox girl with tits the size of my girlfriend's is my little brother?"

"Wow, Shoko was right, you are smart." Itsuka laughed, she had a pretty laugh. No! Bad Fuyumi! You were in a loving relationship with a smoking hot girlfriend! Don't start flirting with your now apparently little sister's smoking hot friends! And apparently they were all dating? What the hell was this lesbian love pile and how did they get an invitation? "But yeah, Shoko asked Izuku to use his quirk to turn her into a girl, but uhh, has she always been so spacey?"

"Yeah, she has," Fuyumi let her shoulders slump. She'd have to go check her texts again and make sure that Shoko didn't send a text saying that she was Shoko now. "And who's Izuku, and does his quirk let people change gender?"

"Kinda," Itsuka shook her hand back and forth. "His quirk is a bit uhh, unique. But Izuku is-"

"Our boyfriend." Shoko said bluntly. "Oh, and we have another girlfriend called Momo, and then there's Menu-chan. I don't know what to think about her. Also do you like my ears?"

"Yes," Fuyumi gave a nervous chuckle. "Your ears are very cute. So, let me get this straight, you went from having zero interest in girls, to having three girlfriends and a boyfriend?" Shoko nodded. "What the hell happened?"

Shoko placed a hand on her stomach and gave a smile that was way too cute for the line that followed it. "I had good soba."

Fuyumi sighed, Itsuka doing the exact same thing.

What on earth was their father going to think about all of this?

"Wait, where are the other two you mentioned? Uhh, Izuku and Momo?" Fuyumi asked, looking between the two other girls. The ones without animal ears. Though, they did make Shoko look just that extra bit cuter.

"Probably having sex." Nejire hummed, arms behind her back as she smiled, her large chest sticking out and nearly dwarfing any pair that Fuyumi had seen before. They also looked a lot nicer too. Dammit. What were the odds that Izuku's mysterious quirk was the reason for those things as well?

"Right, well, good to know, let's uhh, let's focus on shopping then." Fuyumi gave her best laugh, though to her surprise, having a little sister was actually quite nice, and her sister's girlfriends were certainly fun to be around too.

Still, her father was a bit of a concern.

XXXX

Once again Izuku was reminded that as calm, nice, and just so womanly Momo was, when it came to a fight, she was twice as scary as Itsuka was. And Itsuka had years of training because she lived above a dojo run by her father. Momo had like six months with Alfred and she turned scary.

Izuku watched as the ceiling became the floor and back again, while his arm pulled his body around. Then he hit the mat and found himself staring up at the ceiling, Momo's brutal combat smile fading from her face and a small smile gracing her lips. "I think that's my win."

"All the wins are yours." Izuku grumbled, barely able to stand up after a throw like that. He wasn't even sure what the hell just happened. Man, he might be able to put up against someone more normal, but all of his girlfriends kicked his ass. Well, he might stand a chance against Shoko if she didn't use her quirk, but he saw Itsuka bend a crowbar the other day and had mixed feelings about that.

"Thanks." Momo laughed, pulling off her padded headgear, her padded gloves were next before she finally pulled her hair out of her long black ponytail, letting those thick locks fall free around her back. Honestly, it was almost as good as stripping. "Now then, I think you deserve a reward."

Little Izuku knew exactly what that meant. And big Izuku grabbed his sports bottle and chugged it like it was his life line.

[Your stamina has been restored. Go get em.]

He should probably keep on the protective gear.

[Coward.]

Momo grabbed the back of his head and forced the helmet off before she kissed him, her fingers deep into his hair. And he returned the favor, her body was slick from sweat as he grabbed her wide hips, feeling the slick fabric of her work out shorts before he moved up, and up, and up towards that glorious zipper that managed to hold her sports bra together. He touched it for just a moment before Momo pulled back.

"Hold on, I want to try something." Momo grabbed his arms and pulled him over to a free weight bench.

"Should I be worried?" Izuku asked, he was still wearing the gloves. He sat down and watched as Momo adjusted her sports bra a bit. She rolled up the bottom just a bit and somehow made her cleavage just more present. It was kind of hot. Okay, it was a lot of hot. "And less clothed?"

"Less clothed is a must." Momo smiled and got down onto her knees. She then grabbed onto his pants and yanked them down, exposing his now very hard dick. Honestly, ever since he had moved into this place his dick had been harder than it had been when he was thirteen. Then again, he lived with some of the most beautiful women in the entire world, so he had a good reason to be horny as all hell.

Plus, those girls were equally horny.

Oh. And Momo was really hot.

Really really hot.

Like, even when she was covered in sweat, she just looked divine.

She grabbed his dick, carefully moving her tongue to his tip and locking eyes with him. A blow job? While they were still so sweaty? He wasn't going to say no. She swallowed him carefully just taking the tip into her mouth, her tongue still swirling inside and driving him absolutely crazy.

"Momo, that feels good," He half said breathlessly, moving his hand to push her hair out of her face. She redoubled her efforts and sucked on the top just the slightest bit harder, and then let it all out with a satisfying pop.

"Well then, tell me how this feels." Momo brought her breasts up, her tight sports bra straining to contain them. "Just sit back and relax Izuku. I've been wanting to do this for a while now."

Hearing that felt almost as good as his dick sliding between Momo's tightly packed tits. It was completely different from sex or a blow job, a tit fuck was something new. Something amazing. And no doubt Momo's breasts were some of the best for something like this, their fullness, size, and texture all squeezing his dick to capacity.

Momo began to move her breasts, both hands on her sports bra as she bounced up and down, his dick head barely managing to appear in the shadows of her cleavage. "Well Izuku? How's this feel? It feels good, right?"

"It," He swallowed, feeling a shiver go through his body. Wait, already? Was he seriously going to cum already? "I think I'm going to-"

He exploded, his thick white goo shooting up and covering Momo's face.

"Uhh, sorry." He said, rubbing the back of his head, and watching as Momo sat there blinking at the sudden explosion of cum. "I umm, yeah, that felt pretty good. Really good actually. Sorry Momo."

"Hehe, don't worry about it." She stood with a smile on her face, then unzipped her bra, finally letting those large breasts of hers free. A thick layer of cum was resting between them. Did he really cum that much? That felt like a lot. "You'll just have to make up for it by fucking me clean in the shower right?"

And just like that his dick was ready for round two, and three, and four.

On the plus side, his stamina was really going through the roof with four crazy horny girlfriends.

XXXX

Shoko considered this to be inevitable.

It was only a matter of time before her father found out about her new gender and demanded to see her. So now, she was standing in her father's office, completely bored out of her mind dealing with this purely so she wouldn't have to deal with it later. She wanted to go back and eat Izuku's soba.

Or maybe more of that green mushroom thing he made last night.

She was mostly just hungry.

And horny.

And bored.

"Are you done glaring at me?" She asked, crossing her arms in front of her chest and making sure to flick her tail in annoyance. Having a tail was fun. "Can I go now?"

"Will this affect your training?" Her father growled, her flames glowing brighter by the second. "You're still going to surpass All Might like this. Correct?"

Shoko rolled her eyes, considering how Itsuka had All Might's quirk now and there was no way in hell that Shoko was going to get through that girls absurd defense anytime soon surpassing All Might felt kind of moot. That and she was really happy with her life right now.

"Actually," She blinked and started to use both her ice and fire. She created a turning pit of ice right, and a similar pattern of fire to her left. Time to show off her new feat. "It's actually made me a lot stronger."

Bounding out from the fire and the ice emerged two vulpine constructs, each the size of a car, glistening with the power of the element that created them.

Seeing her father's eyes go wide was worth the trip over here.
