Heavy breathing.

Sweat dripping.

Skin on skin.

Gasps..whines...

Muffled moans, and bite marks on pale skin.

Midoriya Izuku is in utter bliss as he lies on his back having his mind blown by Bakugou Katsuki.

At least 3 times a week they meet like this, between 10pm-1am in Izuku's dorm. Sometimes, but very rarely, Izuku comes to him. Katsuki doesn't normally want Izuku in his personal space, but his desire to have mind blowing sex is too great, so he endures the All Might posters and bed sheets instead. Sometimes, he is tired enough to allow him entrance into his dorm. But those nights are rare.

"Ahhhh—-Yes—Right there!!"

"Fuck— Deku~So tight!—Shit!"

They need to be careful of their volume. They have already moved the bed so it's no longer up against the wall, and have tried to shift their weight so the frame doesn't squeak. They are also rarely in the position they are in now, but someone was feeling needy. Izuku's face is normally pressed onto a pillow, and his ass is in the air, so any noises he makes can be muffled. Katsuki also can't contain himself when he hears the sounds he produces from the smaller boy's mouth. Izuku's noises make Katsuki's own voice start to respond, and neither of them are quiet.

"I'm s-so close Kacchan— you feel so good~~"

"Deku—f-fuck! Shit!!"

A hand moves over Izuku's mouth, and another around his length. It's getting late, and Katsuki is getting desperate. His movements are also getting sloppy as he chases his orgasm. He needs Izuku to be quiet. But he also wants him to cum.

A muffled cry erupts from Izuku's mouth, and his vision goes white. It's like nothing else matters as his body starts shaking. Katsuki follows soon after.

The heavy breathing slows as both start to come down. It's always in this position that Izuku is surprised with a kiss - almost like a thank you - planted on him before Katsuki pulls out.

Before he gets up, he cleans them up and discards the condom. Clothes are tossed back on, and a blanket is thrown over the fast asleep boy on the bed before he walks back to his dorm to go to sleep.

No words exchanged, no goodbye kisses given, and neither of them ever stay the night.

It's just sex. An arrangement they made 2 years ago at the end of their first year. It started as just a once a month thing - new and thrilling, but also terrifying. It then turned into a once a week thing, and now it's an at least 3 times a week (though, depending on the amount of stress, it can be everyday) thing.

And it's just sex. For both of them. Very little kissing is involved, no cuddling, and just enough foreplay to make the sex enjoyable.

They have tried so many things. Katsuki will even bottom for him every once in awhile. It feels good either way, and that's ultimately all that matters.

(Don't tell anyone that Katsuki Katsuki isn't always a top, he'd kick your ass.)

They were each other's firsts, and are still one another's only.

Katsuki doesn't share. He also doesn't trust anyone else to be clean. Because sometimes they use condoms, sometimes they don't. It depends on how they're feeling. That night, they were feeling lazy, and not using condoms requires extra clean up that neither of them felt like engaging in. Although neither of them would admit it.. they didn't just have sex today because it was a particularly stressful day. No, they were just really fucking horny.

Izuku would be lying if he said that he didn't find Katsuki attractive. There were days during class after they'd endured a rather tough training where Katsuki looked really, really hot. The way sweat dripped from his body, and the material of his costume clinging to sticky skin, drove him absolutely insane. His chest was one of Izuku's favorite features. He loved those solid pecs, and his toned abs. He loved to run his tongue over them, and the noises that Katsuki made when he did.. were like music to his ears.

And Katsuki? Well, he would also being lying if he said he didn't like that ass. Izuku's hero costume didn't leave much to the imagination when it came to the curve and overall shape of his butt. Katsuki, and others in his class, have caught themselves staring more than a few times. He also loves the shape of his lips, and the strong muscles in his thighs. His arms are also very impressive, and although he doesn't use them much anymore when he fights, he sure knows how to hold him down and bend him over to fuck the ever living shit out of him. And when he did that, there was no escape. So yeah, he also found Izuku to be very attractive, but like hell he would let him know that.

No, Katsuki and Izuku didn't like each other. They lusted after one another to no end. But they would never show this lust in front of anyone else. They hardly showed it to each other if they could help it. The most risky thing they've done, which is a thrill to them both, is sex in the public showers of the locker room. They like to wait until they know everyone else has finished changing and showering, and then have loud and nasty sex in the shower stalls. Sometimes, they cannot wait until later that night at the dorms. And Katsuki is a bit of an exhibitionist.

Two years ago outside the dorms, Katsuki was pissed. Izuku had yet again, come out ahead of him during a rescue exercise in class that day. He decided he needed to confront him about it, because clearly the other had cheated. He must have There was no other explanation. At least not one that Katsuki's prideful ass would admit to.

It was 10 pm, and Katsuki knocked on Izuku's dorm door, commanding him to confront him outside behind the dorms in 10 minutes. Izuku rarely ever refused a request that Katsuki asked of him. At that time, he still feared the blond, and knew if he didn't meet him outside, it would just mean hell for him later.

When he got outside, he was instantly met with fists and explosions.

He reacted instantly, dodging and fighting back. This was after their fight at ground beta, neither of them have learned. Izuku,however, was determined to beat him, and part of him found a lot of excitement in fighting him like this. He quickly realized though that he was going to be beat. After a extraordinarily painful punch to his abdomen, he was doubled over, and the contents of his stomach spewed out.

A normal, rational thinking person, would stop and realize they have won. Not Katsuki. Instead, he seized this opportunity to pummel him to the ground, causing him to practically choke on his vomit.

After shifting his head to the side so he didn't choke - Katsuki didn't want to kill the boy - he waited for him to stop coughing before leaning in close to his ear and whispering the sinful words that would start everything.

"I won Nerd. But you know, there are other things you can choke on. All this vomit ain't a good look for you."

Izuku managed to push the hands holding his head away from his face enough to wipe his mouth and produce a response. Katsuki's hands moved to Izuku's cheeks, leaving his face only inches away from the boy below him. Selecting his words carefully, Izuku cleared his throat.

Although there were still times when he still really feared him, he was secretly really turned on from these fights. There was no way in Izuku's mind that Katsuki meant what he just said to be interpreted any other way than how he interpreted it. What he was about to allow to come out of his mouth would change everything.

"Oh yea Kacchan? And what would that be? Your cock? I bet you get off on beating my ass don't you?"

Izuku braced himself for what he thought might be another blow to his stomach or face. But instead, as he clenched his eyes shut, he was met with hot lips slamming into his own. The kiss was messy and filled with teeth, but the desire behind it was clear. It didn't take long for him to return the sentiment, for him to wind his arms around Katsuki's neck to pull him in and deepen it. It was his first kiss, and judging by Katsuki's awkwardness, he'd guessed it was his as well.

What started as a kiss quickly turned into Katsuki grinding himself downward against him, tearing off his clothes. Thankfully, they were far enough away from the dorms that no one saw. They didn't have sex that first night, but Katsuki did get some of the best head he'd ever receive. He'd told him to put his money where his mouth was, and to suck the cock the knew he craved. Izuku did so willingly.

Katsuki had bitten his knuckles so hard trying not to moan that they bled. Izuku was blessed to hear some of them sneak out though, and they further fueled him to suck Katsuki's cock like his life depended on it. He blew his load into the back of Izuku's throat and watched as the other swallowed it all, licking up all that was left on his slowly softening cock.

Katsuki decided to reward him. Calloused hands roughly jerked Izuku off, and lips connected to his own to muffle the moans being produced. It didn't take long for him to be pushed over the edge, seed spilling all over Katsuki's hand.

After a few moments, Katsuki wiped his hand on the grass, pulled his clothes back on, and started to walk back to the dorms. Izuku was left half naked on the ground just watching Katsuki walk away. He quickly threw on his own clothes, trying to catch up with the blond.

"Wait!! K-Kacchan!-- Stop!"

Izuku tripped and fell on his face in the effort to reach him, and as he fell to the ground, Katsuki stopped. He didn't even turn around to say his next and final words.

"Tell no one. You hear me? NO ONE."

Izuku merely stayed there in the grass, watching him go. He waited until he was no longer able to see him before he got up to head back.

Neither of them talked about what happened. Weeks passed, and people were starting to take notice that they barely spoke to one another. How were they supposed to move on from that?

Izuku was confused. He didn't think he liked Katsuki like that, never thought of him as more than his childhood friend. Someone he admired, someone that he looked up to - not someone he wanted to have sex and a relationship with. But he was so turned on that night. He loved the skin on skin contact, and the orgasm he had was like nothing he had ever experienced.

Katsuki also would never admit to any feelings whatsoever for the Nerd. Never. Hell, he's the one who initiated the encounter. He had no idea what to say. He knew he wanted more, though. But feelings for Izuku? Yea, right. No. He was a punching bag with hot lips.. or no, not hot. Katsuki did not think anything about the boy he's been beating for the past few years was hot. Nor would he ever admit that he ended up with the best sleep of his life that night, thanks to that insane orgasm. Nope. Never.

It wasn't until he was studying one night with Kirishima that Katsuki was asked about what was going on between him and Izuku. Kirishima was his best friend. He also secretly thought Izuku was really cute. He watched the two of them very closely, and knew there was something 'off'. He wasn't sure what, but the tension they created was starting to make a lot of people in their class very uncomfortable.

He took in a deep breath before asking, "So, what's up with you and Midoriya? Did you guys get into another fight or something?" Red brows furrowed with concern. "You guys have barely spoken in weeks. I thought things were better after house arrest? I mean, you don't even threaten him outside of class anymore."

Katsuki glared at the red head. Like hell he'd tell him about what they had done together that night. Nah, not happening. But he did realize it might be time for him to get a grip. He wasn't acting like himself.

"Shit, nothing is going on between me and that Nerd. We fought. That's it."

Kirishima knew there was something more to it, but didn't want to pry. Instead, he smiled and thought for a moment before voicing what he wanted to say next.

"Well, maybe you two should talk. It's starting to make people uncomfortable, bro. I know you couldn't care less about what anyone else thinks... But the last thing you want is for this to affect your performance." The redhead noticed that this got Katsuki's attention, so he continued with that line of thinking, "You've seemed distracted when you fight! You're better than how you have been lately, man... maybe talking will help?" He also wanted to stop seeing the cute little cinnamon roll that was Midoriya Izuku look so stressed out.

Fuck that. But then again... he didn't want these feelings to negatively impact his performance and lead people to think he was weak. He was not weak.

"Tch. I'm fine. Now, get back to work," Katsuki scoffed, "You're going to fucking fail our next test if you keep thinking about me and that god damned nerd. Got it?"

Kirishima smiled to himself and decided to drop it. He knew he got through to him.

Uraraka, Ashido, and Izuku were hanging out in the common room that same night watching videos on YouTube when Katsuki walked in to get a bottle of water from the kitchen. Izuku suddenly tensed, immediately clamming up and not speaking again until after Katsuki had left. After he entered the elevator, Izuku noticeably relaxed.

Uraraka and Ashido have been watching this type of thing happen for weeks, but it was Ashido who decided to address the elephant in the room,"So.. Midoriya.. What's up with you and Bakugou? Did you get into another bad fight or something, hon? You've been super tense around him!"

"Yeah.. are you OK, Deku?" Uraraka asked tentatively, "You guys have barely spoken... I know you aren't really friends, but things seemed to be looking up for awhile there."

Izuku wrung his hands, remembering what Katsuki said to him that night behind the dorms,"Tell no one. You hear me? NO ONE"

There was no way he was going to tell them. Katsuki detested him, or so he thought, and he didn't even want to think about what he would do if Katsuki found out that someone knew what they had done. He needed to try his best to act natural. Nothing was going on. He was fine.

"I-I'm fine guys... Really! K-Kacchan is... j-just Kacchan. W-we had a, uh, a fight. Nothing more!"

Ashido knew there was more to it.. but she decided to drop it in the face of Izuku's clear discomfort with the matter. They spent the rest of their evening doing as they routinely do: watching YouTube videos, and giggling about the boys and people in them.

Izuku came out to Uraraka and Ashido not too long after their midterm exams. It was becoming obvious to Izuku that Uraraka liked him in more than a friendship way... and well, he would never like her like that. So, he told her one night in the common room that he was gay... so as to save her feelings in the long run. Ashido was there for moral support. They made sure to keep it quiet, though. Outside of Ashido and Uraraka, only Izuku's mom knew, and well, Katsuki presumably knew now.

Later that night, Katsuki knew he needed to talk to Izuku.. knew he needed to talk more about their.. situation.

It was 10 pm when Katsuki made his way to the second floor to confront Deku. Along the way, he was super careful not to be seen either. He took the back stairs, and though they were drafty and creepy as fuck, he knew no one else would be around. He didn't need anyone asking him why he was visiting Deku this late at night. Yes, for someone who normally goes to bed at 8:30, this was late.

Even his knock was probably more tentatively than the usual slamming and shouting he would lay on Kirishima's door.

Izuku was awake. He doesn't normally go to bed at a decent hour, investing more time than the average student taking notes and studying. He has to document all the events of his day into his notebooks! He learns so much. So, he needs to take it down in order to remember it all. The knock at the door startled him, though. He normally doesn't have visitors, especially not at - he glanced at the clock by his bed - 10 pm?!

"Coming!"

He quickly put away his hero notebook and made his way to the door. The visitor outside didn't say a word to offer any hint as to who they were, and this made him just a little nervous. He cracked open the door slowly and was surprised when his eyes met crimson..

"K-kacchan!"

"Let me in, Nerd."

He quickly let him in, and as soon as he was, Katsuki locked the door behind him. This action didn't go unnoticed by the smaller hero.

"S-so, ah... what do you need t-to talk about Kacchan?" Izuku stumbled, stepping backward into his room and a few more steps away from Katsuki.

Katsuki was silent. He was pacing the room and looked to be deep in thought. This was making Izuku very nervous. Katsuki was wearing a simple pair of black sweat pants and a black tank top. His arms and chest were shown off very well with the top he was wearing, and Izuku couldn't help but take notice. Although the scowl on Katsuki's face made him nervous, he was also kinda turned on by the body in front of him.

He was internally cursing himself, now was not the time to be thinking about that.

When he finally stopped pacing, Katsuki stopped right in front of the smaller boy and slammed him into the wall, pinning his hands above his head with one hand, and shoving his knee between his legs. The other hand was was placed on Izuku's hip, holding him in place.

"I don't like you, Deku," he growled.

"I-I know Kacchan..."

Katsuki pressed his body further into Deku's, chests now touching, and brought his knee up to press again against his crotch. Deku couldn't help but start to feel aroused. He could feel himself beginning to harden, and he let out a small whimper.

Katsuki leaned closer, breath fanning over the other's ear, voice husky,"Stop. Talking."

Izuku whimpered again and sweat began to bead at his brow. There was no denying how hard he was now. The hot breath in his ear sent shivers down his spine, causing all the blood to rush down to his lower region.

"Tch. Pervert, you like this don't you?"

Izuku nodded his head. He was told not to speak and didn't want to anger the blond further.

Katsuki smirked. "Again, I don't like you, Nerd.. but, I do like.. this"

He moved his knee from between Izuku's legs and replaced it with his hand, forcefully shoving it through the opening in the All Might pajama bottoms and gripping the hard length inside. He spread the precum on his tip with this thumb, wrenching a small moan of pleasure from the smaller man.

"I see you do, too."

Izuku nodded again, eyes wide, still too nervous to speak.

"Speak, Deku. I need you to tell me."

His mouth was dry, and he was nervous. Izuku swallowed and licked his lips before responding.

"Y-yes.. I-I like this, too.."

His eyes darted down to the ground, and he couldn't help but notice the tent in Katsuki's pants.

"Good."

He leaned in close to Izuku's ear again, this time kissing right behind it before he spoke, "Then let's make a deal. As long as you tell no one about this, how 'bout you let me do whatever I want to your body, and in turn, I'll let you suck my cock and even fuck you with it," he raised a brow, smug, "How does that sound... De-ku?"

Izuku let out another moan, everything he said sounded so hot.. and it was an offer he could not refuse.

"O-okay.. b-but if I don't like something.. Y-you need to stop. You can do whatever you want.. w-within reason, unless I, uh, say not to."

Katsuki rolled his eyes. He didn't want to rape him, so making sure he liked something was always a part of the plan. He'd let the nerd think that he came up with that, though. The blond moved away from his ear to look him in the eyes.

"Fine. Do we have a deal?"

Izuku's mind was going a million miles a second. He no longer felt in control of the words about to come out of his mouth. He knew this arrangement was dirty and risky, but his needy body really didn't care. He liked the thrill of it all and the excitement of possibly getting caught.

"Yes. We have a deal."

"Good," he leaned back in, this time pulling those pajama bottoms off completely.

And so it began.
