"We'll be having a week break. Since the USJ attack, we thought it'd be good to let you take a break. But don't think it'll be easy when you get back. Class dismissed."
School ends after a ton of eyes darting over to me then looking away when I catch them. I tap my alternate self's shoulder. "Come on, let's walk home." I say, and she shudders again. She packs her stuff up and nods her head. The girls watch in jealousy, all of them wanting her to be them.

We walk out in silence, the hallway being lively as everyone is excited to go to their homes or go out somewhere.
"What's your name?" I ask, causing her to tense up a bit more. 'Why is she nervous?'
"I-izumi Midoriya. Y-you're Izuku M-midoriya.." She replies, shaking a bit.
All of a sudden, I hear a female voice behind me. "Uhmm.. Midoriya?" We both turn around to the female voice, to see the holy one, Ibara Shiozaki. "Yeah?" Izumi replies. "Why are there two of you? No offense.. but to be honest, she doesn't even look a girl.." She says bluntly. "Oh, because he's not. He's a g-guy." She replies. "A GUY?! PLEASE DON'T RAPE ME!" She yells, as she activates her quirk immediately. 'Holy shit.. what'd I do?' "A GUY?!" The girls around us shout. They all activate their quirks, ready to beat the shit out of me.

"Ladies! Ladies! Calm down." The voice came from the principal. 'Nezumi you lifesaver!' I say in my mind. "I know guys are supposed to be disgusting pigs and like to rape and rob girls. But him, he's different. He has a quirk!" She says excitedly. "A QUIRK?!" The same girls shout. They go from fear to admiration really quickly.

I quickly grab Izumi's hand and dash out of there, thankfully escaping before they swarmed us.
I sigh in relief as I pant, landing in front of my apartment building. "Before we enter, let's speak over there." I say, pointing to a opening to an alleyway. "Okay.." She replies, obviously hesitant.

I lean against a side of the wall, getting ready to speak. "I'm.. not from here." "What do you m-mean..?" She asks confused. "I died in another world, and woke up here thanks to god." I reply. "Horokoshi?" She asks. "No, god." "Yeah, Horokoshi."

I sigh but it quickly turns into a chuckle, and she giggles. "Okay.. continue." She says, done laughing. "You see, I'm you.. but from another universe." I say. "Wait, so that me and you aren't blood related?!" She asks excitedly. "Guess not." I reply. "Yay! Yay! Y-" She stops as she realizes what she's doing.
I sigh as I pat her on the head to calm her down. She pouts while we walk out the alleyway opening, back towards the apartments.

She opens the door, and I follow. Instantly, a very good smell enters my nose. 'Ohhhh shit..'

"Izumi honey! Foods ready!" Inko yells from the kitchen. "Okay! Wait up!" Izumi shouts back.
She leads me to the kitchen, and gains her attention by tapping the wall. "Hm? What is it ho-"
She sees me.

"W-wait.. I didn't have twins.." She says confused. "W-why is her body.. so masculine?" She says, as she sees nothing on my chest, and pants instead of a skirt. "W-well, because it's a he." Izumi replies. "Wait.. a h-he? IS IT A LONG LOST BABY?! OH COME HERE!" She runs up to me and gives me a crushing bear hug. I smile as I see Izumi looking at me, a blush forming on her face.

"So.. can I call you mom?" I ask. "Yes! Of course you can! It doesn't matter about gender in this home!" She replies excitedly. "Now, go with your sister as she gives you a tour of the home. I'll be making another dish of Katsudon!
'I love you mom.' I say to myself as I follow Izumi.
I sit on the girly bed, and lay down, my legs coming off the bed.

"So, what's your quirk?" I ask, curious on if she has One For All. "I-it's a stockpiling qu-" She gets interrupted by me standing and my mouth next to her ear. "I know about One For All too." Followed by me blowing into her ear, causing her to blush madly.

I could tell I was seducing her, as she held a massive blush on her face. "I-i have One For All too.." She says nervously, wanting more.

"Okay, good to know. I'll take a nap really quickly so wa-" I get interrupted. "No.. I want more.." She says, as if she was horny. "More what?" I ask. She jumps onto the bed, now on top of me.

I get this looks like some incest shit, but honestly I don't care right now.

She hungrily makes out with me, grinding on me. My face turns tomato as my attempt to seduce got 'reversed' on me.

But, as if on instinct.. my hands move to her ass.

I give it a hard squeeze, and she gives a muffled moan in the make out session. It all stops in one moment though.

"Kids~! Dinner is ready!" We hear our mom calling out for dinner. "L-let's do more.. later.. please.." Izumi pleads, still on top of me. I nod nervously, and put a hand in my pocket to make it seem like I don't have an erection.

Timeskip, Nighttime
"Sooo.. mom where am I gonna sleep?" I ask while she's reading a book. "With Izumi. You don't mind do you?" She asks, glaring at me with a friendly smile. 'Horrifying.'
"Y-yeah, I don't mind. Goodnight Mom." "You're forgetting something!" She pouts. "Right."

I kiss her on the cheek and walk towards Izumi's room, she said she'd come here to take a nap.

The door's already slightly opened, so I peek to see if she's asleep or not.
Well, she's enjoying herself.

Masturbating, moaning out a name. My name.
'I'll just sleep on the couch..' I say to myself. As I walk into the living room, I run into my mom who's about to leave the house for some reason. "Where are you going?" She asks. "The c-couch.." I reply nervously. 'But where's she going?' "No, you're sleeping with Izumi. You see, she hasn't had any action and I want grand babies soon." She says seriously. "W-wait, that's incest and underage sex!" I reply, whispering. "What's incest?"
I mentally facepalm. 'Right, this isn't my world.'

"Plus, consent is at 13 years of age. So, underage doesn't apply here." She says. 'Holy shit, what is wrong with this world?!' I get snapped out of my thoughts as she continues. "But since I can wait 3 more years, here." She hands me a condom. My face turns into a tomato once again. "You want me.. to have s-s-sex with her?" I ask, anxiety and excitement shooting up. "Correct. Plus, it looks like she's having fun right now." She points to Izumi's bedroom door, and she walks to it. She puts her ear against the wall, not the door since it'll open. I put my ear against the wall, and what I hear excites me.

"Izuku! Izuku! Oh god~"

A small smile forms on my face while Inko giggles excitedly. "I'll be out for tonight. Good luck, Izuku."

She walks out the door, leaving me and Izumi home alone for the night.

Mini Lemon starts here!

Out of pure instinct, I open the door to her room, in a loud noise from the door. She freezes as her head slowly turns, her hands drenched.
My excitement rises, and not only that.

She only had a crop top on with no bra underneath, and nothing under that. "I-i-izuku?!" She shouts nervously, scrambling to cover herself. I don't say a word to her as I rip off the covers, and slowly get on top of her. Our hands connected, as I start to make out with her angrily. She moans, definitely liking this side of me.

She rips open my shirt, adding to the seductive vibe in the air. I tear off her crop top as we flip, now her being on top of me. She was definitely fit, thanks to All Might. Not really muscular, but you can see a defined 6 pack on her. Plus, all natural, which means better.
We flip over, her now being over me.
She had large breasts, and her ass having no exception. Caught up in the moment, she rips my shorts off.

'This'll be a long night..' I say to myself, as she gets smacked by my member in the face.

Timeskip, 1 Week Later
Break was over, and school was back. Izumi holds my hand as she leans her head on my shoulder, as we're heading to school. We've only smashed once, for 6 hours straight. After that was just sneaky blowjobs and handjobs, not complaining.

We arrive, the normally shy Izumi Midoriya now bubbly and happy.
The girls were obviously jealous. The way she was on him, and how her mood changed drastically.

One of the girls, finally decided to make their move. She walks alongside Izuku, and taps his shoulder. "Hey, new boy.. what's your name?" She asks, nervously. "Izuku Midoriya. Yours?" I reply, Izumi tightening her grip on my hand. "I-itsuka Kendo." She replies. "Hey! Don't hog all the man-meat!" Says a girl with short black hair. My hand gets even more squeezed, and it's becoming painful.

"Izumi.. that hurts.." I say to her. "Hmph." She pouts as she looks away. "Uhm.. Midoriya?" Both oh our heads go towards Itsuka. "The guy.." She assures. "Yo." "C-can I get your number?"
I remember my phone contacts, only 2 people.
So, I was desperate. "Sure." Is all I answer with, and she happily squeals as she gets her phone out. "Hey! What about me?" The blackette asks. "Sure." She squeals happily too as she gets her phone out.
I show them my phone number, and they Usain Bolt my shit on their phones. I get a message from them at the same time, both saying 'Hiiiiii'

"Whoa whoa whoa! What am I missing out on?" The female Kirishima says, looking over my shoulder. "Oooh! I want your phone number!" She looks over, typing my number into her phone.

Izumi sighs as she makes me follow her into the building, the other girls following too. She whispers into my ear. "We're doing it all night as a punishment. I'll be dominant." She says, causing me to uncontrollably smile. I get a whisper in the ear from another girl. "Me and Yui just agreed on something. Meet us at the end of class at the entrance okay? Only you." She says. It caused my uncontrollable smile to turn into a massive smile. Even Koro-sensei can't compete.
