He get's destroyed!

Before Izuku can do anything, Ochako runs behind him and pulls him down so her dick is between his ass cheeks.

Ochako: I call dibs on his anal virginity!

Tooru: NO!

Before any of the other girls can do anything, Mina grabs his head and pulls it down so his face is floating in front of her balls.

Mina: And I take his first time oral sex!

Momo: Damnit! We can't change that, we said first come, first served...

Ochako: Yay! Get ready Izuku! Here I come!

She lifts his skirt a bit and pulls down his panties before slowly going inside him. Izuku muffled screams as Ochako pushes herself forward, moaning at how tight his ass is.

Ochako: God you feel good.

Mina can't hold back anymore and removes Izuku's gag.

Izuku: Mi-

But the moment he opens his mouth, Mina rams her dick into his mouth. She moans as he screams as Ochako goes deeper and deeper. Mina goes deep inside and starts fucking his throat. He chokes as he feels the huge meat rod move up and down his throat. But suddenly he has to moan and Ochako starts to grin.

Ochako: I found your G-spot, Izuku~

Ochako picks up the pace as she begins thrusting, and Mina follows suit. Izuku can't help but moan now, he's never felt anything like that before. He looks to the side and sees how the other girls have got out their cellphones and are filming him and masturbating at the same time. Ochako speeds up and holds on to him tighter. He can feel her dick starting to throb.

Ochako: God, I'm about to cum, get ready Izuku, I'm cumming inside you!

Mina: Same Ochako! Get ready to swallow Izuku!

The only thing Izuku was able to do was shake a little as he felt Ochako load her load into him. To him it felt like someone stuck a hose up his ass and turned on the water. Ochako moans as she holds onto Izuku tightly. Mina is no better when she cums in his mouth, he thinks he's never eaten anything as salty as her cum. He desperately tries to swallow all the cum but it's hard with the amount.

Mina: Yeah! Swallow it, Midori! I see in your eyes how you like it!

Ochako pulls out and a large amount of cum comes out of his ass, he sighs in relief as the pressure in his ass slowly eases, but it doesn't last long as Kyoka grabs his ass.

Kyoka: My turn~

She immediately sticks her dick inside him and starts thrusting, Izuku moans as this happens and she spanks his ass.

Kyoka: Yeah you little slut! You like that don't you?

Mina pulls out as well, but another shot of cum comes out of her dick and shoots him right in the face. Tsuyu grabs his head and puts her dick on his lips.

Tsuyu: My turn. Open wide, Izuku.

Tsuyu puts her dick in his mouth and follows Mina's example by throat fucking him. The two don't hold back as they fuck him at full speed. Izuku moans at every thrust and punch from Kyoka. After a few minutes, the two cum at the same time, filling him with even more cum.

Kyoka: God! That was nice!

With a last firm smack on the already red cheeks she pulls out and some cum comes out.

Tsuyu: You're really good at it, Izuku. Ribbit.

She pulls out, he has to cough up some cum, but gets another small load in his face. But before he can be happy that he doesn't have any more dick in his mouth, Momo puts hers in. He looks up and sees her standing there with her phone taking some photos.

Momo: You look so cute like this~ Get ready for my nectar

She grabs his pigtails and uses them to thrust.

Tooru: Well my turn now!

He didn't think it could get any bigger than the other two girls, but Tooru's dick feels almost twice as big. She moans as she goes deeper and deeper. The other girls say they can even see the dick bumping into his stomach. But what gets him moaning is when she starts thrusting, he feels pain and pleasure at the same time.

Tooru: How many times have I wanted to do that! I fill you up well now!

With one last thrust, she cums inside him, his stomach getting bigger from all the cum shot into him. Momo cums as well and pulls out with a satisfying smile.

Momo: Ah that was good. Ochako you can lower him now.

Ochako disables her quirk and Izuku falls to the floor in the cum lying there, sitting down and breathing heavily as the girls surround him.

Tsuyu: So Izuku, we have a request for you now.

Ochako: Yeah, you're going to be our little sissy and we don't send everyone the pictures and videos we took of you.

Kyoka: Then you can continue living your heroic life and we get our little cum slut.

Momo holds up her phone with a grin and makes a copy of the key to his Chasity Cage.

Momo: Ain't like you got much of a choice~

Izuku looks up with a few tears in his eyes before nodding.

Izuku: O-okay... I will be your little sissy....
