Katsuki Bakugou

Bakugou held the smaller boy to his chest, listening to the small snores of the passed out omega. Two days had passed and Bakugou felt his control slipping away bit by each time Izuku would be writhing with his heat. He kept holding his breath, pinching his legs, pulling his hair, reminding himself of the promise he made to Izuku, trying anything and everything to remain in control so he did not break his promise. 

Izuku was not making it easy for him either, the shit-head smelt so fucking good and every time Bakugou got him off, the next wave would make him braver an more bold. Izuku would beg and plead, saying that it wasn't enough and he needed 'his alpha'. Bakugou never let anything go past him jerking the omega off or going down on him, turns out Izuku's nipples are super sensitive as well when he is in heat, one time Bakugou actually made him cum from nipple stimulation alone.

Bakugou was still amazed at how he had not gone into rut this time around and how he had managed avoiding having hot sex with the lustful omega. It was extremely painful after a while though, after that first time of Izuku sucking him off, the omega had been so worn down and tired from his heat that he physically could not help the alpha. Bakugou would take care of Izuku, then rush to the bathroom and finish himself off. It was never as good as he wished it could be, when he would finish it would leave him a little breathless but nor fully satisfied. He wanted Izuku.

As morning came around, Bakugou woke up to warbled moans and wiggling beside him. He blinked the sleep from his eyes and looked over to see Izuku on his hands and knees with two fingers sunk into his ass. The sight alone was enough to have the alpha fully erect and possessively growling at the boy.

"I'm s-sorry, Kacchan..." Izuku whimpered and looked embarrassed for a moment before squeezing his eyes shut and moaning.

"Don't be sorry, Deku," Bakugou growled and moved quickly over to the omega, climbing in bed with him. He then looked over Izuku's sweating body, his eyes landing on those slim fingers that were fucking himself. There was something to be said about how, for a moment, the alpha felt dumbfounded and shocked. His whole body frozen as he watched Izuku get himself off in his bed. He hated that the omega was suffering because of him but he wanted to make him feel good. He wanted to make the pain go away, his own lust set aside as he watched the omega tremble.

"Stop." the blonde said and he grabbed Izuku's wrist, pulling his hands away and leaving Izuku feeling rather empty again.

"No p-please I need it!" Izuku shamelessly begged. Bakugou rolled his eyes and held up three fingers to Izuku's mouth.

"Suck." the alpha ordered and Izuku's eyes widened before he clammed down on the alpha's much larger fingers, sucking and licking them until they were coated. Soon after, the alpha had removed his fingers from Izuku's mouth, he reached his hand behind the omega and pushed one finger inside the trembling boy's entrance. It went in smoothly and Bakugou watched as the omega's eyes flew open and a loud and needy moan ripped through him. He smirked and felt himself slip back into his own lust, pulling his finger out and thrusting it back in before adding his second finger. Izuku yelped and the alpha slowly started pumping his fingers inside the boy, feeling his walls clench around them.

"Fuck, Izuku you think you can take one more?" the blonde asked and the omega all but screamed when Bakugou's fingers brushed his prostate.

"Fuck! Bakugou please! Yes I can take it!" Izuku shouted and the alpha growled happily before adding a third finger, stretching and scissoring the omega open. Izuku's words become mushed and slurred, the air was filled with lusty cries and choked out sobs of pleasure. Bakugou reached under the omega and gripped his member, giving it some attention while his other hand fucked him into tears.

"Cum, my little omega." Bakugou muttered against Izuku's spine, the alpha was hunched over behind him, kissing and licking his back as bringing hot waves of pleasure to the omega under him.

Izuku lost all control and spilled himself into the alpha's hand, his hole clenching and twitching around Bakugou's fingers, letting a loud scream of pleasure sound off. Bakugou growled, hearing his name roll off the omega's sore lips. He slowly pulled his hand away and gently cupped his hip, helping him lie down, the omega instantly falling limp. His breathing still rugged and his body trembling. 

Bakugou went to the bathroom and getting a wash-rag, soaking it in warm water and then going back to the bed and cleaning off the omega's body. It was hard for him to shower in the state he was in, so the alpha opted to just wash off his body at least twice a day, sometimes more if things got messy. To most people, an omega's heat seems enticing and sexy. The idea of a horny omega willing and wanting to fuck anything that offers itself to them, makes most horny alpha's toes curl and sets their teeth on edge. For Bakugou, after experiencing this side of it, not getting to actually fulfill his own biological need to mate and knot the omega, left him with a better understanding and appreciation of just how strong this omega is. Of course he still wanted to pound into Izuku like a wild animal, but something inside him wouldn't let that happen. He promised Izuku he would not do that, he respected the boy far too much. Izuku had chosen him to be his heat partner after all, he wanted to take care of the omega. Letting his alpha instinct take over, he washed and adjusted the omega's now-sleeping body into a more comfortable position, stroking his hair and murmuring quiet praises into his ear.

Izuku Midoriya

His body was tired and sore, the activities of the past 3 days had been the most intense experiences he had ever felt. Part of him was dreading today, his heat had stopped last night he was almost positive, now he had to get back into the swing of normal life. With hazy memories of what actually happened over the past few days, all he knows is that he is covered in love bites, scratches, and his hips and back hurt really bad. Izuku had woken up alone for the fist time since his heat began, part of him instantly felt sick, wondering where Bakugou was, another side of him wanted nothing more than a long, hot shower to wash away all the sticky shame that clung to him.  It wasn't nearly as bad as it usually is, considering he does remember Bakugou cleaning him every so often in between his waves.

Izuku winced when he stood up, a shooting pain down his backside. Fuck, what if they had actually had sex? Was Bakugou able to control himself? His mind was playing through as much of the events that he could remember but they all went blank midway through each memory. Maybe that is why Bakugou left, he must have know he did something wrong.

Izuku felt a deep nagging in his stomach and he pushed it away, staggering to the shower attached to Bakugou's room. The shower was long and Izuku felt the need to get out when after around 20 minutes, his legs were growing weak. Re-dressing was a challenge as well, he had no clean clothes in Bakugou's room. With a towel wrapped around his hips, he hurried across the hall to his room and put some clothes on, instantly feeling better after a shower and fresh clothing.

There was a banging on his door that mad him jump and then wince at the pain throbbing in his hips. Izuku shuffled to the door and pulled it open slowly. 

Bakugou was standing there, a look of concern on his face that instantly relaxed when he saw that Izuku was standing there.

"Come in?" Izuku hesitantly asked and stepped aside, making room for the blonde to walk in. Bakugou stepped inside and followed Izuku to the bed, where Izuku sat down, wincing and then rubbing his hips. Bakugou's face flushed a bit and he muttered.

"Sorry for your hips or whatever."

"Y-yeah... Um... They really hurt... We didn't... you know? Did we?" Izuku looked uncomfortable and Bakugou's eyes widened.

"You really don't remember do you?" He said, a bit of shock laced with his voice. He looked at the omega, who now had wide eyes and he looked really upset. "No, no, no! We didn't... I mean, I didn't... I promised you I wouldn't..." Bakugou quickly added in, trying to calm the panic look on the omega's face. It worked, his mouth relaxed and his eyebrows furrowed slightly.

"...Oh" Izuku sighed and bit his lip. "Thank you... And sorry, for jumping conclusions..." Izuku blushed and ran his fingers through his slightly damp hair.

"Tsk, whatever... So, are you good? Like, you're heat is over and shit?" Bakugou grumbled, going back to his usual sparky self.

"Yeah, it should be. I just need to rest now. I should be back to normal tomorrow." Izuku said and watched Bakugou, his lips moving before his brain could recognize what he was saying.

"Bakugou, what is going on between us?"

The blonde stilled for a moment before running his fingers through his hair.

"I don't fucking know" His voice sounded more frustrated than angry.

"Was it just... I don't know.. Instinct? Or was it something more?" Izuku said quietly, knowing that the alpha' hearing was superb. Izuku felt a little deflated, he didn't know why but he wanted to hear Bakugou say that it was something more for him. Izuku knew there were some feeling involved with them, it made him buzz with energy when they were together. His body would turn towards Bakugou's direction when in the same room. They shared lingering glances and would seem to get along, some times. Bakugou sighed.

"I don't know what I am feeling Deku, but it was something more than instinct... If it was purely instinct I wouldn't have kept my promise... But, I somehow managed to keep my word. For three fucking days." Bakugou groaned and rolled his eyes, making Izuku smile a bit.

"I am glad... I didn't want to regret my first time. Not that I would regret it with you! Ah, I mean... I just didn't want to not be able to remember my first time! I knew I could trust you, b-but I am glad to hear we didn't have sex! Ah, shit..." Izuku rambled before just tugging in his hair and shutting his yapping mouth. Bakugou looked at him with a curious smirk before sitting down beside him and taking his hand, holding it between his two larger hands. Izuku took a deep breath and sighed, relaxing some.

"Relax, Izuku..." Bakugou sighed and the two boy's sat in the comfortable quiet for some time.

"I want there to be more to us... More than the lust...." Izuku started but was cut off when Bakugou swiftly pressed his lips into Izuku's lips. A small gasp puffed out and Izuku kissed back slowly. This was different than he remembered, Bakugou gently cupped his jaw and kissed Izuku softly, leaving nothing to be desired when he pulled away, the kiss settled any doubts and nerves he had previously.

"I want more too. I don't know how to do this whole relationship thing, but I don't want to ever see you with someone else, and that's how I know that there is more to us..." Bakugou shared and Izuku smiled softly, leaning in to peck Bakugou on the lips once more.

"I want that too, Kacchan... I want to try this, see where it goes. I want us to be more than just heat partners or scent buddies... I like you..." Izuku blushed and Bakugou's lips curled, showing his teeth in a silly grin. He wrapped his arms around Izuku's waist and was about to pull him over towards him when Izuku hissed out in pain.

"Ah, fuck. Why do my hips hurt so bad?" Izuku grumbled and Bakugou quickly released him and blushed.

"Ah, well... It's a long story, I kind of... fingered you?" Bakugou said, blushing harder now. Izuku's face heated up and he groaned, hiding his face in his hands.

"Should I have not done that?" Bakugou asked, getting worried.

"No, no, that's not it! It's just embarrassing..." Izuku groaned and suddenly Bakugou laughed, a real fucking laugh.

"That's what you're embarrassed about? Not all the moaning and the fact that I have now seen your orgasm face, and I was the one who caused said orgasms?" Bakugou teased and Izuku rubbed his face, trying to rid it of the blush.

"Ugh, stop talking." Izuku begged with a small shy smile. Bakugou chuckled and leaned over, removing Izuku's hands from his face and pressing a small kiss to his cheek.

"Alright, for now..." Bakugou smirked and gently hugged Izuku to his side, being sure to watch his face for any discomfort. Izuku only sighed and snuggled into Bakugou's side, nuzzling into his neck and humming happily. The two boys sat like that for about 10 minutes until Izuku's stomach growled loudly, breaking the tender moment.

"Time to feed the beast." Bakugou muttered and snickered. Izuku bit his lip and rolled his eyes, enjoying how things have seemed to calm down and go back to a normal type conversation.

"Yeah, I'm starving." Izuku chuckled and smirked happily to himself.
