Controlling Your Instincts
"Yes Alpha" Kirishima blushed as the words slipped out of his mouth, his head tilting in submission. The fear Izuku had planted in him as he said these words combined with his inability to move made him let these dangerous words out.
Izuku gulped hard as he stared down at the smaller alpha in front of him, these words were never meant to say as an alpha. It meant that he knowledge the other as his superior, as better than him. That other was his alpha, that was giving up his status to him.
He would practically be his bitchslave beta, an offer that nobody turned down without a good reason. Izuku's instincts screamed at him to claim the cute boy under him, to fuck that guy through and mark him for everyone to see.
To breed that disrespectful bastard that dared to say he wanted to fuck him, to let him give birth to his pups.
Izuku had never in his life fought so hard before, his hands clenched down so hard he could. The boy under him hissed at the pain, but that didn't matter to him.
Just one wrong move and he would ruin this guy's future, even if it was him that challenged his luck. He felt how the boy had used his quirk to hinder him from breaking his bones, smart one at least.
Think Izuku think, his mother always told him that he should always make sure that the person is in his right mind. That he should respect them like he wanted to be respected because his quirk and Prime Alpha status were given to him.
He had done nothing to earn them, luck and just luck alone had given him power, he would not abuse it.
"You will slowly make your way to the door and lock it once you are out. Don't run, if you run you will have my cock up your ass in a minute. Now go" Izuku said as he forced his hands to let go of his prey.
Kirishima listened as he slowly walked over to the door, he took the key from the inside before locked the door once he was out.
Izuku relaxed as he let himself fall to the ground, he breathed in a couple of times. His breathing became more normal as his instincts relaxed, he needed to make sure that the boy was okay.
Izuku moved to the door as he thought about what to tell the boy, he wasn't going to ruin him with a claiming mark. He would have all rights over that person, he could forbid him from attending U.A.
"My instincts are calm now, you can open the door" Izuku heard how the other took a shaky breath before the key turned.
Izuku grabbed the other by his neck the moment he could, just because he calmed his instincts didn't mean his mind was.
"Kneel there and I dare you to move" Izuku hissed out as he sat down on the bed, the naked boy kneeling in front of him. His cock was still rock hard from his rut, he just hoped that it was over soon.
"Do you have any idea how incredibly stupid and dangerous your words were?" Izuku said as a rush of anger went through him.
"If I had any less control and you would be my fucking bitch now, didn't they teach you in school that you don't say these words, as an alpha no less" Izuku ranted as Kirishima looked at the ground in shame.
"Do you have no pride as an alpha?" Izuku said or more than asked. Though the reaction was surprising, the boy stood up as he stared at him down.
"Of course, I have" He growled out as his canines showed.
"Then act like it" Izuku yelled back.
"How?" Kirishima yelled back in frustration.
"Control your instincts god dammed" Izuku said frustrated.
"How the hell do I do that"
"How about you will your fucking cock down for the start" Izuku said as he tossed the boy's t-shirt and pants before he found the underwear.
Kirishima put his clothes on as Izuku went to the table to do the same, they needed to calm down. Alphas fighting would only result in pheromones being sent out that made them even more aggressive.
"Okay, I know that you are in your rut and mentally even more unstable as it should be. Let's sit down for a moment before we continue" Izuku said as they both set at the bed. Silence took over them and Izuku noted the smell of arousal coming from Kirishima.
It seemed that the shock was over, and his lust started to take over, he will train this boy a little for now. It was dangerous for an alpha to run around like this, if he continues like this then he will really end as a cock warmer.
"Okay, I will show you how I trained. You have to find the confidence in yourself, not your alpha, but your human being. You have to understand that you are a human being that has instincts, but also a mind that is way more powerful." Izuku explained as the other listened.
"We will start slow, I will set a timer of an hour. Until the time is over you will not touch yourself, you will sit still and read something." Izuku said as he got his book from the table he had worked with.
"This will help you to understand that you are more than just instincts, I will reward you if you manage it." Izuku said as he pulled his phone out and set a timer.
Two days continued like this, Kirishima had to control himself always an hour after each orgasm. It was painful, stressful and tiring, but it also helped him.
He could feel it, how he had control over his instincts. Midoriya always rewarded him with a hand-job if he managed it, it wasn't nearly as good as his blowjob, but it was still a lot better as his own.
For an alpha Midoriya showed a godly amount of patience for him, he was forgiving and always helped if he could. The only time Midoriya growled at him aggressively was when his phone ringed and he wanted to give it to him, but it was normal for alphas to be possessive.
Izuku called his mother each day to have her know where he was and that he was safe, it seemed that his mother worried quite a lot. Unlike his parents that left him with a stranger and never called, but in their defense, he didn't call them either.
"Okay, your rut is almost over, let us speed things up" Midoriya said as he stood before him, the lost three days he had come to the conclusion that Midoriya was the nicest person he had ever met.
That guy forgives him for forcing his cock down his throat or for calling him slut and other things. If he had been in Midoriya's position, well let’s say the cock warmer didn't sound too bad.
"I will touch you around your body, you will hold your instincts under control" Midoriya instructed and he just nodded.
Midoriya then slowly started to round him like he was his prey, his instincts instructed him already to go into defense position.
He stayed still as Midoriya's hand touched his naked back, then it touched his left hand. He felt how the alpha in him wanted to growl or attack directly, he can do that, he will restrain himself.
A touch to his cock let him squirm, but he was getting used to being touched there. Midoriya's hands traveled over his entire body over time and he was proud of himself that nothing more than a growl escaped him.
That was until the hand touched his ass, this was a no-go for another alpha to touch there.
"Now let's see if you are good enough for this" The alpha in him rose to the challenge, he will show him how under control he was.
Midoriya's hand stayed at his ass as they continued to squeeze his butt, he even gave them a small smack. Kirishima couldn't hide his smug smile as he didn't react, his inner alpha was fighting with all his might to get away.
All his thoughts stopped when Midoriya pocked against his hole, he was about to turn around when a strong hand on his neck prevented it.
"You have come this far, are you sure that you want to give up?" Midoriya's tone was mocking, challenging his alpha to handle it, but at the same time, his alpha wanted that finger away from there.
An Alphas hole was never touched, it was a signal to give up his status. It was the same as the words he had said, but he said them and here he was still an alpha. He brought up all his willpower to overwrite the feeling to lash out.
"Good boy" Midoriya praised as he circled the hole, what came next shocked him as Midoriya pushed his finger in.
He lost it as his canines showed and he growled dangerously low at Midoriya, he was about to attack when Midoriya pressed him against the floor.
"I'm sorry, but I'm not so forgiving as you might think. Coming down my throat, calling me slut, begging for cock, but my favorite was cock warmer. You damaged a huge amount of my pride as alpha, so I will have to put you into your place." Midoriya said as he started to thrust his finger roughly in and out of him, he whimpered as his ass ached.
He tried to get free, but Midoriya like always had completely overpowered him. This was humiliating in so many ways, his alpha instincts were throwing a tantrum.
The taller alpha ignored his shouts as he put a second finger in him, they opened him up as he gave up getting free. Then it struck him, an electric pulse of pleasure shot through him.
He moaned shamelessly as Midoriya started to hit this spot over and over again, after two minutes he was a mess. His cock rock hard as he was still pressed against the floor, then horror overcame him as he was felt that he was about to come.
He was about to come from his fucking ass, no even worse, he was coming from his ass that was finger fucked by an ALPHA.
"Are you enjoying yourself Kirishima? Because I do, seeing you like this I start to regret not having claimed you" What? What the fuck was happening, was Midoriya enjoying fucking him up like this or that he could put him in his place.
"This hot body, not like the pitying build beta's and omega's had, but still small enough that you wouldn't look weird setting in my lap" A blush formed on Kirishima's face as he heard Midoriya's words. Nobody had told him that they liked this build, he was always too small to be a proper alpha.
"This cute pink hole clenching around my fingers, how it would feel around my cock" Midoriya whispered as he was just inches away from his face, he then buried his nose into his scent gland and took a deep breath.
"Fuck yes, your scent is so delicious. I have fucked countless beta and omegas, their scent while sweet is already fast to get sick of. Yours, this smell of mountain fresh air, always so refreshing and nostalgic." Okay, he must be in the wrong movie, who in the world liked his scent. It was weak and pathetic, but it seemed that Midoriya liked it.
"Maybe I should make you mine now, you would be such a good pup for me. You would make me happy, would carry my pups" Izuku said and the praises added with the prostate stimulation brought him over the edge as he came with the loudest moan he could make.
