Whenever you and Midoriya would hang out, it was always at your dorm. You both knew he was pretty embarrassed about showing people his own dorm because he was a fanboy. So, you agreed to always stay in your dorm when you hung out.
Midoriya had been your best friend since you were both young, since you had been the only person to be able to calm Katsuki down and get him to stop making fun or Midoriya. You thought it wrong to bully the poor kid for something he couldn't control. Eventually, the three of you had gotten into a Poly-amorous relationship.
Your own quirk was decently strong, like everyone else's. You had a quirk that allowed you to shape-shift. The only downside was however long you shifted, that would be the amount of time you had before you could shift again.
"Hey Izuku." You grinned, looking up at the already flustered boy. He looked down at you, as you were laying across his lap.
"Yes, [Y/N]?" He responded, playing with your hair.
It was a quick transformation, as you really only added cat ears- of which caused your human ears to disappear- and a long, slender tail.
"Nya." You said, causing you both to burst out laughing.
"Do you wike me now Izuku-kun UwU" You said through laughs. Midoriya poked your ears, causing you to giggle.
"That's adorable!" He exclaims, scratching the spot between your ears. This sent you into absolute bliss. You pushed your head up against his hand, as Bakugo, your other boyfriend, walked in.
"I brought cookies-" He said, holding a box before looking up and seeing you with cat ears and a cat tail being pet by Midoriya.
"Hey Katsuki-" You said, giving a small wave. Katsuki scoffed and rolled his eyes, sitting down on the bed next to you. "What are you two fucking doing?" He asks, sitting down the box and kissing your cheek.
"Having fun!" You purred, laying across Katsuki as well as Izuku.
Katsuki scoffed, rolling his eyes and running his fingers through your hair. He wasn't exactly the happiest about Deku being a part of your relationship, but as long as he had you he would be just fine.
You wiggled your way off of Izuku and onto Katsuki's lap, locking lips with him. He was quick to kiss back, running his tongue across your bottom lip as to ask for permission. You stubbornly denied, causing him to snake a hand down and squeeze your ass which made you gasp as he thrust his tongue into your mouth.
You allowed him to take control as he moved to kissing your neck, and you reached out to Izuku, who had just been watching in embarrassment. Katsuki did not like that and gently bit down on your neck, causing you to moan. "Ka-Katsuki." You moaned out as he grinned against your neck.
Izuku made his way over and his hand touched the hem of your shirt. "Are you okay with this, [Y/N]?" He asked. He was much gentler than Katsuki.
You nodded, assisting him in taking your shirt off. You also started removing your bra, making sure to tease the two boys as you fidgeted with the clip/bottom {Whatever type of bra you prefer}
Impatience taking over, Katsuki roughly removed your bra and Izuku gently latched onto one of the rosy pink buds, his tongue flicking over it. "Izuku!" You moaned out, gripping tightly onto Katsuki's shirt.
Katsuki, upset that Izuku was getting more attention, trailed a hand to the top of your pants/skirt. He looked at you, his eyes asking for permission. You nodded, and his hand slipped inside of your pants/skirt and began playing with your clit.
Biting your lip, you tried to keep the moans that threatened to escape out. Izuku was rolling his fingers over one of your nipples and gently sucking on and flicking his tongue over the other, and Katsuki slipped a finger inside your wet pussy. No longer being able to hold it in, you moaned out Katsuki's name as he thrust his long fingers inside, eventually adding another one.
The amount of pleasure the two males made you feel was amazing, and you moaned out their names.
Katsuki slipped his fingers out, and Izuku pulled back from your breasts, causing you to whine in disappointment.
"Don't worry [Y/N]." Katsuki says huskily, hooking his thumbs in the band of your pants/skirt. He pulled them down, looking up first for your approval. As he pulled your pants/skirt down, he pulled down your panties with it. He picked you up and placed you down where Izuku had laid down, placing you on top of him. You moaned as Izuku pushed himself inside of you, having taken off his pants and boxers when you were being pleasured by Katsuki. "Iz-Izuku!" You moaned out, gripping onto the sheets.
You felt something wet at your ass, and looked back to see Katsuki holding a bottle of lube. "This may hurt at first baby, okay?" He says, pushing himself inside of your ass.
You shouted out in pain, your eyes tearing up. Izuku wiped them away, having also stopped to allow you to adjust to the pain of Katsuki being in your ass.
After a few moments, Katsuki moved to test the waters and you moaned out his name, to which he grinned and started going a bit faster. Izuku started thrusting, his hands grabbing your hips. "Nng.. [Y/N]" Izuku groaned, thrusting in and out of you.
It's like the two males were in sync, one went out and the other slammed back it. Your moans filled the air, along with the occasional groan of one of the two males. You felt yourself nearing climax, unable to stand the pleasure of being fucked like this anymore.
"Izuku! Bakugo!" You moaned out as you came, the two coming shortly after you did.
Sorry this sucks ass >-< I'm not the best at writing threesomes
