Abusive! Cheater! Katsuki Bakugou X Abused! Male Reader X Izuku Midoriya
|3rd POV: Childhood!|

"You want Me to be your what?" the little boy questioned looking up from his book "My boyfriend. I don't really know what it is, but I know it's when you want to be closer than friends." Bakugou pointed out sitting on the bench. "Okay." the other boy said pulling out a crudely drawn stick figure out of his book giving it life. Katsuki hugged the other boy nuzzling him "Thanks Y/n, and also can you promise Me one thing?" he nodded as he gave another stick figure life "Promise Me that you'll never leave Me, no matter what I do, a-and you'll have to listen to Me no matter what." Y/n nodded as Katsuki looked at the stick figures hugging.

|Present|

You looked as Katsuki teased Izuku again, burning his book and throwing it out the window. "Uh... don't you think that's going a little too much, Katsuki?" You said as he glared at you "Shut up! Why are you defending him anyways?! He doesn't have a quirk, yet he's applying!" you shrugged "So what?! He could be the first hero without a quirk! Like Batman." you said with a cat smile, which earned you an explosive punch in the gut. "Shut up, Y/n!" he yelled kicking you in the stomach. "Ka-" "STAY OUT OF THIS DEKU!" Midoriya clasped his mouth shut watching as Bakugou took his rage out on you. "When we get home, you're gonna be so sorry." he said confusing Izuku.

You two did live together in a small apartment, paid by your parents who wanted you to get out of the house. Katsuki moved in with you when he had found out, his mother checks on him sometimes.

"See ya' Zuku." You said as you were dragged out.

~<><><><><>

The walk home was scary, though you are taller than him, you were weaker than him (physically). "Y/n." Bakugou stopped making you freeze "Yeah?" you questioned as he laughed turning around "Stay away from Deku. I don't want you anywhere near him." your eyes widen as he said that "B-But, Katsu! Midoriya, is My only friend! You've made Me cut ties with all My friends, why?" He walked up to you and hugged you. He firmly held onto your back as he did an explosive punch making you fall to the ground "What was that? I couldn't hear you." you stood up holding your gut crying slightly "I said I don't wanna leave IzuKU!" Katsuki kneed you in the stomach and grabbed your face, covering your mouth.

"Shut it! Unless you wanna lose your mouth." he snickered as you heard small popping around his hand. Nodding Bakugou let you go as you stood up "I'm sorry Katsu, I'll stop talking to Izuku." you sobbed as he glared "Oh, and one more thing," you looked at him as he crossed his arms "From now on it's Master, but when we're with the others it's whatever you want." He said turning around.

|Skip to U.A|

Entering the classroom, you saw Izuku. Huh, he got in? "Oh, hey Y/n!" he said running up to you. You ignored him knowing Katsuki was watching "Y/n?" he looked at you worried "What's wrong? This is a new school, shouldn't you be happy?" you looked away, but Izuku didn't get your signal. "Y/n, answer Me. Something is clearly wrong." you looked at him gritting your teeth "Get away from Me you quirkless bastard!" you noticed after saying that he had a shocked look. You wrote in your book and showed Izuku "Katsuki said I'm not allowed to talk to you anymore. I'm sorry for the insult, but can you please just leave Me alone." Midoriya nodded and left.

Katsuki then walked up to you snatching the book, he then gave a glare "This still counts as talking to him." he muttered burning the book. "I'm sorry Katsu, I didn't mean to." He leaned down to look at you "Then why do it in the first place? If you knew you weren't supposed to talk to him!" you thank god All Might came in with something in his arms "Student's! Today we'll be doing the Hero's and Villain's exercise again! Come on now!" he said zooming out.

~<><><><><>

You stood with the crowd shaking as you heard what was just said "Hero's, Midoriya, and Y/n! Villains, Bakugou and Todoroki." Looking at Bakugou he had his eyes on both you and Midoriya.

"Alright get into position, but this time it's not a villains protect the weapon, it's a hostage situation." All Might said walking off with the rest of the group.

~<><><><><>

As All Might said go you entered the building "Hey, Zuku. You go save the hostage dummy's." He nodded and ran off "Y'know I was gonna go after Deku, but you still decided to talk to him. Even if this is training, you still need to follow what I say." Katsuki said coming from the other hall way "Oh well," He chuckled cracking his knuckled "Guess I'll have to take it out on you!" He yelled launching at you.

You jumped at his sudden action, and quickly acted by putting paint on the floor and raising your hand. The floor reacted to the ink, creating a wall. "Sorry!" you said as Bakugou had hit his face on the wall. Katsuki then blew up the wall to see you not there "Come out Y/n! This won't hurt as much of you just take it." he said stepping while not noticing the trap you had set for him, that had blew up trapping him in an ink web. He shouted as he made a massive explosion, burning the ink in the process "GAAAHHH! You're so dead!"

While you ran through the halls hearing the explosions behind you as they got rapidly closer "Don't have time to make another trap, gotta improvise!" you thought aloud taking out a needle and pricking yourself dropping blood along the way. "Got you!" you ducked as Bakugou went flying passed you "I'm gonna blow your tongue off, so you won't talk back!" you shuttered "I'm sorry, but you'll need to find Me first." you said as the drops of blood turned into clones of you. He frowned while laughing "I don't care! I'll do it to everyone till I find the real you!" he said running into the crowd of clones.

While All Might was observing the others were slightly confused "Why is he saying sorry to Bakugou?! He doesn't do that to anybody else, when their his opponents." All Might then looked at the students "It appears we have a relationship right here, and it seems like a toxic one." He said turning back to the match.

"Bakugou please stop! Why are you doing this in the first place? I don't understand." you said as he destroyed the last clone "Because you're mine!" he said punching you in the face "You're mine. You have to do everything I say, and you can't leave Me. You promised long ago." He said holding you by your throat "Then why are you so jealous of everyone else? If I had promised then there's no need for you to cut Me off from My friends!"

Bakugou looked at you blankly "It doesn't matter. I need to shut you up." He said throwing you to the floor, and straddling you. He opened your mouth and pulled your tongue out "You won't feel that much pain." He said pointing his sparking finger at your tongue. "YOUNG BAKUGOU, STOP THIS AT ONCE OR YOUR EXPELLED!" All Might threatened, making Bakugou stop "Damn, we'll continue this at home." he said getting up and going after Midoriya, leaving you panting on the floor crying.

|Skip to end of school|

You sat at the front of the school waiting for Bakugou. "Where is he?" You questioned looking at the setting sun "Hey." you look behind you to see Izuku "Hey, Zuku. You know I'm not supposed to be talking to you right. So leave." He sat near you "But he's not here. He left with Eijiro." You looked surprised "Oh, I guess he forgot to tell Me." you said looking at your phone. "Wanna come over to My house?" Izuku offered "I guess, Bakugou won't know." You smiled at the small act of rebellion you just committed.

~<><><><><>

You sat on his bed as you two watched old All Might videos on your phone. He moved closer making your faces squish against each other "Izuku." He looked at you "Yeah?" turning off your phone you looked at him "Do you think I should leave Bakugou?" he nodded "Yes, We've all seen how he abuses you during the training." you started to cry with out noticing. "Then I'll leave him, and maybe I can find someone else soon. What do you think Zuku?" You were then kissed after finishing your sentence.

"Izuku~" you moaned as he straddled you "Once you break up with him... c-can you date Me?" you nodded "Do mind if we take a secret test run?" you asked receiving a kiss as an answer.

|Bakugou POV|

I sat on Kirishima's bed looking at My phone "What's up?" he said looking over My shoulder "Think he found out?" I shook My head "I don't know." I said lying down "Why don't you leave him? I laughed "I like leading him on. He's just so weak, he bends to My will so easily. Though I still kinda love him... a lot." Kirishima laughed "Nice. Wanna go again?" I nodded tackling him down.

|With you: 3rd POV|

"Y/n, I-I'm gonna!" Izuku couldn't finish his sentence as he came on his sheets, as you came in the condom. You laid next to him with a real smile on your face "Thank you, Deku~" you said dozing off. 'He- He called Me Deku! He never called Me that.' Izuku thought before passing out.

~<><><><><>

"What were you doing at his house." you looked to the side of the classroom, looking at everyone watching "None of your business." you sighed. "What did you say?!" you glared at him "You heard Me. None of your business." he grabbed you by your shirt "Why the sudden boost of confidence? I'll still kick your ass." You smirked "Go ahead. I'm done with you." the class gasped as Bakugou had a hurt look "Why? You promised you wouldn't leave Me." he said as tears built up in his eyes "I'm sorry." you raised a brow "Sorry isn't gonna cut it, not after all you've done, and that promise. I didn't know what you were talking about anyways, and when I did find out what you meant I was really happy. Then you turned out to be a bigger ass than Momo's real ass." you said as he wiped his tears away "What ever I was doing it with Kirishima."

You raise both brows "Oh, so you cheated on Me? Even more reason for Me to leave you." you said standing up and looking down at him "That whole promise was bull shit! So screw you."

You felt so refreshed and happy just saying that, then you turned to Midoriya "Keeping My promise. You wanna go out Izuku?" Bakugou looked at him and gritted his teeth "What is it with you! Always trying to one up, Deku!" you stepped in front of Bakugou "Don't try anything, or so help Me I'll gut you like a fish." you said making him flinch "S-Screw you! You won't *gasp!*" you made him stop by holding a blade you made with your blood. "I'm serious."

Bakugou backed off and sat at his desk. You were amazed by what you did, you never felt like this before.

~<><><><><>

You stood on a hill talking to Midoriya, and you noticed Bakugou watching from downhill with a clear view of the both of you. You smirked grabbing Midoriya by his waist making him blush "Y-Y/n, what are you" you kissed him. Dragging him down on the blanket you two had out there. "Y/n~" he moaned as you slid his pants down "Ride Me, Deku." you whispered in his ear "But we're in public." you chuckled "No ones gonna see trust Me, not many people know about this hill."
