Chapter Text
"You're staring," Mina told Denki with an amused smile.
"Sorry." It made Denki blush a little, the beta realising he had indeed been staring at Katsuki for quite some time. But how could he not when Katsuki was wearing a black suit that looked so damn hot on him, his half-opened white shirt and lack of tie making the alpha look even more handsome?
Today was the day they were graduating, and so UA had organised a small party in the dorms where all the students could come. There was music, food and drinks; no alcohol, of course, but some people had brought their own in secret so that everyone could have fun.
It was a great party all in all but, even though Denki was surrounded by his friends, he simply wasn't able to enjoy the moment.
"You think he's gonna fuck her?" Sero asked and Denki felt his heart painfully clench inside his chest in response. The reason why he couldn't have a good time was because an omega girl was talking to Katsuki, the way she was batting her eyelashes at the alpha enough to guess what were her intentions.
"I'm sure he will. He always does." Kirishima said with a chuckle.
The thing was that Katsuki was a player. It often was the case for dominant alphas. Actually, as soon as his first rut had arrived in his last year of middle school, Katsuki had developed the habit of sleeping around. He didn't even have to try to find someone to sleep with: omegas were instinctively drawn to him and would do anything to spend a night with him.
It irritated Denki like nothing else could. Each time Katsuki left to fuck someone, it filled him with intense anger and indescribable sorrow. The only thing that reassured him was the fact that Katsuki never seemed to sleep with the same person twice.
"Maybe he won't. We don't know." Mina said as she gently squeezed Denki's arm to comfort him. She was the only one to know about his feelings among their group of friends.
Denki didn't know why but he had developed feelings for Katsuki throughout his time at UA. It had started as mere admiration. Katsuki was incredible, after all; always at the top of his game and so skilled no one could compare. He was everything Denki wasn't: smart and naturally talented.
Then, admiration had slowly turned into lust. Katsuki was sinfully handsome, it was a fact. He had beautiful eyes and sexy muscles, his body so hot Denki often found himself hiding his erection when they were training together.
He had known he was bisexual for a while now and had no problem admitting he was attracted to both guys and girls. Everyone knew it too since he had dated Jirou in their second year of high school then Ojiro in their third year.
However, both relationships didn't last long since they weren't the person Denki really wanted...
He was in love with Katsuki. He had realised it not too long ago, but he was sure of it and knew his feelings wouldn't disappear any time soon. It was quite hard to accept when he perfectly knew Katsuki would never agree to date him. Katsuki wasn't interested in anything serious. He thought it was a pain in the ass and much preferred to focus on his future carrier as a hero.
Still, it didn't prevent him from fucking someone different almost every day.
"Look. They're leaving." Kirishima pointed to Katsuki and the omega girl heading toward the exit, the sight making Sero laugh. "Yeah. No need to be a genius to know what they're gonna do." They were all used to Katsuki's behaviour, by now.
"I'm going, too." Denki unexpectedly stated.
"What? Where?" It surprised his friends, a worried look taking over Mina's features as she looked at Denki with concern. "Just to get some fresh air, don't worry." The blond beta answered half-heartedly.
The truth was that he was sick of watching other people sleep with Katsuki. If Katsuki was fine with anyone that looked cute, then why not him? Denki knew he was pretty. He maybe couldn't produce slick like omegas, but his body was great and his mouth did miracles. He'll show Katsuki how good in bed he was.
"Hey, Bakugou!" He called out as he arrived in the corridor where he had followed Katsuki. However, he didn't expect to find Katsuki with a hand already down the omega's skirt, the girl quickly pushing Katsuki away when she noticed Denki.
"What the fuck do you want, dunce face? Can't you fucking see I'm busy?" Katsuki exasperatedly growled at Denki's interruption.
"Yeah, I can see that..." The blond beta embarrassingly blushed in response, not knowing how to act after what he had just seen. Katsuki sure moved fast.
"So what the fuck are you waiting for to piss off?" Katsuki asked and Denki suddenly remembered what he was here for, determination quickly replacing embarrassment as he focused all of his attention on Katsuki.
"Do it with me instead." He suddenly said.
"What?" It obviously took Katsuki aback, the way Denki looked incredibly serious making him frown.
"Just once, please. I want to sleep with you." Denki added in a tone devoid of any hesitation. It was now or never if he wanted to sleep with Katsuki. Today was their last day at UA, and so there was no way to know when Denki would get another occasion like this again.
"And why would I fuck a male beta? You can't even get wet." Katsuki pointed out the obvious.
He didn't mind that Denki was a boy. He had already fucked plenty of male omegas, after all. But Denki was a beta and that changed everything. He didn't have slick and wasn't made to get penetrated. He would need to prep before doing anything and that would annoy Katsuki for sure.
"But you can be rougher with me," Denki replied right away. He had already known what Katsuki would say and so had thought a lot about what he could answer to that. "You can fuck me as hard and as deep as you want, I won't break." He wasn't fragile like a girl or an omega was.
"And you don't even have to use a condom with me." He continued to speak with confidence. He couldn't get pregnant since he was a beta and knew he was clean of any std. Katsuki was too since he always made sure to use protection.
"It means you can come inside me as much as you want." Denki boldly said with a flirty smile. He had to give all he had since he surely wouldn't get a second chance, but it looked like it was working by the way Katsuki was now looking at him with interest. "So, what do you say about it?"
"You really think you can keep up with me?" The blond alpha asked.
"Of course." Denki immediately answered and so Katsuki thought about a few instant, before unexpectedly turning around toward the omega girl he had been about to fuck just seconds ago. "Get lost. I don't fucking need you anymore." He told her without beating around the bush.
"What? You can't be serious?!" She clearly wasn't expecting that, the look of shock and anger on her face making Denki smirk. "Sorry, sweetheart, but you heard him." He told her with a mocking smile. He couldn't help it since he finally wasn't at her place. "Better luck next time."
"Assholes." The girl cursed in response, making sure to bump into Denki's shoulder as she furiously left the corridor.
Denki didn't mind it. Not when he finally was going to have what he had been waiting for for so long. "So, my room or yours?" He asked Katsuki, his heart fluttering inside his chest at the only thought of spending the night with his crush.
"I don't have lube," Katsuki answered and Denki thought he should have known, the fact that Katsuki didn't have lube not being surprising since there was no need for it with omegas. "Right." But it wasn't a problem. Denki had plenty of lube in his room.
"Then, let's go to my room." He told Katsuki before leading the way.
