Izuku Midoriya 

The next morning, the boys were awoken rather abruptly to the sound of more robots outside their cabin. Quickly taking action, Bakugou and Izuku rushed outside only to spot 3 robots in this one location, what surprised them more was that Kirishima and Kaminari were both there as well, struggling to fend off the 3 monster-bots alone.

"Bakubro, Midoriya! Glad to see you both right about now!" Kirishima called out. Bakugou sprung into action, quickly taking down one of the bots and while Izuku ran to Kiri's aid. The fight lasted maybe 10 minutes longer after the arrival of the two boys. Bakugou was a force to be reckoned with, his movements were precise an focused, landing hits every time he threw one. Izuku manged to not break anything in his body when using his quirk, he was successfully able to dismember one of the robots while Kirishima and Kaminari took down the final bot. Izuku was sitting on the forest floor, panting and laughing to himself. Kirishima fist bumped him and chuckled as well.

"Serves those fuckers right." Bakugou snickered and winced a little. His eyes flickered around, trying to see if anyone noticed his pain, of course Izuku did. His eyebrows pulled together a little and Bakugou just waved his hand towards the boy, telling him to drop it. Izuku only rolled his eyes and got up, dusting the dirt from his joggers. Kiri and Kaminari gave their farewells before heading back off towards their cabin, how they got all the way to our location left Izuku dumbfounded. 

Bakugou could tell that Izuku was not going to leave him alone about his injury, and he was right. As soon as they got inside, Izuku approached him with a stern look on his face.

"Okay, now let me see your shoulder." Izuku demanded and Bakugou only sighed, not wanting to upset the boy anymore than he had already the other night. He pulled his left arm over his head, disregarding the shirt he was wearing and tossing it to the floor. Bakugou sat down on the coffee table, making it so Izuku could see better.

"Does it hurt to touch it?" Izuku asked, softly tailing his fingers over the swollen socket. The blonde felt the hairs on his arm stand up at the tender trails Izuku's fingers were making.

"Kind of, but it hurts more when I rotate my arm."

"I am gonna move your arm some, I have fucked up my body so much the last 10 months from this quirk, I can pretty much tell what is wrong." Izuku said and gently took hold of the blonde's arm, moving it slowly around and feeling where the tension started and ended. Bakugou only gritted his teeth and grunted when the boy pulled his arm out and over, trying to stretch the joint. 

"Okay, I see." Izuku said and gently brought his arm back down to his side. Bakugou grunted sarcastically.

"What's wrong with it then, nerd?" 

"You pulled it out of place a little. It needs to be readjusted. I can do it if you'd like." Izuku said mater-of-factly. Bakugou looked back over his shoulder at the boy, he looked serious but caring.

"Tsk. whatever. If it will make it stop hurting." Bakugou shrugged and Izuku nodded.

"It will hurt a bit, but then it will feel better. It will need to be massaged afterwards to help the swelling go down."

"I said okay." Bakugou replied and Izuku grabbed back onto his arm.

"Relax and take a deep breath." Izuku instructed and lifted the boy's arm, adjusting the position and then pausing.

"Okay, one, two, three!" Izuku said and Bakugou breathed in harshly, Izuku twisted the alpha's arm and pulled, adjusting the arm back to the proper place. Bakugou hissed in pain and then hummed in satisfaction when the burning slowly went away and left him able to move his arm a bit better.

"I'm sorry, I know what hurts. I have done it a lot..." Izuku mumbled keeping his hand softly on the blonde's shoulder, rubbing lightly. Bakugou just hums his approval.

"S'fine." Bakugou said now that he seemed to relax some.

"Okay, go lay on your stomach on the bed. I need to massage the muscles so the swelling doesn't get inflamed." Izuku said and moved his hand from Bakugou's shoulder. The alpha gave him a small look before rolling his eyes and going to lay down. The smaller boy followed him, grabbing a bottle of massage oil that was packed in his bag. The students frequently had to get massages from how strenuous their lives were, it is extremely important for them to take care of the bodies that they have. The boy climbed on the bed and hesitated.

"Um, I am gonna have to kind of sit on you since there is not actual table for you to be on." Izuku muttered before swinging a leg over, straddling Bakugou's lower back. Izuku couldn't help but notice how warm the blonde was as well as how well defined and toned his back was. Izuku quickly dripped some oil onto Bakugou's back and tossed the bottle to the side before gently rubbing his hands on the alpha's firm back, spreading the oil around before beginning to knead and rub out some very hard knots in the boy's muscles. There were a few grunts and sighs of pleasure from the blonde that made Izuku's heart beat faster. The boy's hands moved across Bakugou's soft skin, working up to the shoulders and gently working through any knots. Izuku couldn't help but notice how close their bodies were. Bakugou let another groan out when Izuku found a tender spot on the boy's hip.

"Sorry..." Izuku mumbled and gently worked out that knot as well. Bakugou didn't say anything the whole time and just let Izuku fumble around and work out the stress and painful knots from this past week. Izuku smiled and chuckled.

"I am kind of jealous, you're getting spoiled." the younger boy said and then slowly moved off of his perch over the blonde's backside. Bakugou slowly sat up and rotated his arm, wincing a bit. 

"Feels better." He said shortly before adding a quite 'thanks or whatever' on the end. Izuku just smiled and started to slide out of the bed, a firm hand shot out and grabbed his arm.

"Your turn, nerd." Bakugou said gruffly and pointed to the bed. Izuku's face went up in flames as his mind trickled to very risque places. He brushed it off with a smile smile and chuckle.

"You really don't have to do that." Izuku protested, holding his hands up an waving them. Bakugou only rolled his eyes.

"I know, but if I was that fuckin' tense then you must be too." Bakugou said and Izuku thought how nice it would feel to get a massage. He nodded his head and shuffled over on his knees to the center of the bed before tugging his shirt off and tossing it to the side. Izuku flopped down on his stomach and felt as Bakugou's thick thighs shifted and was straddling him. A deep red shade covered his face, and he was thankful it was covered by the pillow he was hugging and shoving his face into. Izuku heard the cap of the oil open and then shivered when a few drops landed on his back, rolling down the groves of his muscles. Izuku's mouth popped open, threatening to release a soft croon. Bakugou's hands went to work, kneading and roaming over his back, working any tension out along the way. Izuku noticed how the blonde's hands would roam up to his shoulders, squeeze, and then in one long stoke pull their way down to his lower back, pausing as his hands reaching the waistband of his joggers.

Izuku keened softly and sighed when Bakugou's firm hand pressed into a knot on his shoulder blade. 

"Damn." Bakugou huffed as he worked on that one spot for a while, causing the omega to groan in pleasure when the knot was fully worked out.

"Feel's good." hummed the younger boy and Bakugou huffed his approval before giving his back one final run-over with his hands. 

"All done." Bakugou said, his voice thick with some kind of hidden emotion that Izuku could not identify. The alpha got up off the bed and Izuku rolled over, stretching and smiled.

"Thank's for that." the omega said happily and Bakugou shrugged.

"Just repaying the favor." he brushed off and headed for the shower to wash off the oil that left a shine to his back. Izuku bit his lip as he watched Bakugou walk away. He looked so good and the way his back rippled as he walked had this omega internally groaning. Why does Bakugou have to be so damn hot? Izuku rolled his eyes at the thought and went to the kitchen to find some breakfast before it was his time to shower.

Katsuki Bakugou

Fuck.

Bakugou stood in the shower, hands pressed firm into the cool tiles of the wall. He looked down his body and groaned when he saw his erection. There is no way he got hard from giving Deku a back rub! Bakugou shut his eyes and let the semi-cold water run down his body, attempting to get his body under control. Those fucking soft moans Deku was releasing were music to his ears. Every little groan and comment made by that fucker had his dick twitching to life, he barely had enough time to finish the massage or else he would have had a full erection poking into that damn nerd. Fuck, Fuck, Fuck.

Bakugou gritted his teeth and moved his hand, wrapping it around his length and giving it a long stroke. Fuck. Bakugou swallowed hard and the sounds of Izuku's moans were filling his head. It was impossible for the alpha to not imagine pinning the omega down and fucking his brains out until he was a pile of fucked-out putty on the bed. Bakugou groaned as he palmed his member and thought about the sickly sweet omega in the next room. He thought about every time his hands found a sweet spot on Izuku's body, the boy would wiggle, brushing his ass against his groin. He almost lost it right then. He thought about the soft yet somehow very firm muscles in Izuku's back, and every time his hands brushed the band of his joggers he swore he heard the little shit moan. His sounds were breathtaking and it confused the hell out of him. Here he was, jerking off in the shower to the thought of Izuku-fucking-Midoriya. 

But he couldn't deny it, his body was reacting to the nerd. It was lust filled, instinct driven, need that clouded his vision. He didn't know how he felt about Izuku, but he did know that he was physically attracted to him. It was no longer something he could deny. Bakugou stroked himself in long hard movements until he felt a familiar warmth in his stomach, building. Images of the smaller boy bent over in the shower, stuffed and stretched by his dick had Bakugou throwing his head back and riding out his orgasm, almost letting Deku's name roll off his lips. Fuck. 

Bakugou came down from his high and let the water wash away all signs of his shame. He quickly washed off and finished his shower before getting out, drying off, and redressing into fresh clothing. His body feeling more relaxed than it has in a while, it had been over a week since he last got off and was feeling a lot better, considering the massive amount of embarrassment from just getting off to Deku. Bakugou was dressed in black skinny jeans with rips in the knees and a red shirt paired with an open leather jacket. He fixed his hair and came out of the bathroom and went straight to the kitchen to grab something to eat.

"Did you eat?" He asked Izuku and heard a small hum back from the boy.

"Yeah I did." Izuku said and got up to head to the shower. Bakugou closed his eyes when the nerd had entered the bathroom and locked the door. If Izuku only knew what he was doing in there not 15 minutes ago, Izuku would probably flip out. He was not stupid, he noticed how the shit-head would watch him come out of the bathroom shirtless. He saw how Izuku's eyes would darken and his mouth would fall open nearly every time they touched each other. He did not know what to do, he cared about Izuku, he did not want to hurt him, but he honestly didn't think he wanted anything more than to have Izuku sexually. He blamed it on biology and the alpha/omega curse of biological cluster-fucks. The fact that omegas and alphas are biologically meant to be together meant nothing, Izuku is a guy first of all. On top of that, Bakugou is not the type to settle down, his career comes first. He is only 17. There is no time to be thinking about mates and all that forever and ever bullshit. So, with that, Bakugou came to the conclusion that it was only lust driven sexual desires, nothing more. Him and Deku would have to break off the scenting thing soon. This is just too much for him to handle right now. 

"Fucking Deku." He muttered to himself and made a bowl of cereal and thought of a way to break things off with the shitty nerd once back at school. He had to end this before he hurt Deku, before he hurt himself thinking he could actually be a good mate, or even just a good friend to the fucker.
