Chapter Text
Your eyes widened and your heart pounded after he said that. He could do that?
Your head was pushed down to look as he did it, his cock getting even bigger with ribs along it. They weren't sharp, they looked smooth and it made you indescribably excited.
"Are you ready baby?"
He cooed and gave your shoulder a gentle kiss.
"It's ready and ribbed for your pleasure."
"Y-yes..."
You panted and he lowered you down, pushing himself inside.
You both moaned together and you could feel him stretching you as he went, his ribbed cock providing an extra level of pleasure as he pushed deeper.
"Look at you, your pussy pulls me in..."
He groaned as he bottomed out.
"It's practically squirting your juices out just to take me..."
He moaned as he slowly started to lift you up and down.
"Fuck..."
You moaned out, you could see how deep he was going as he kept your head pushed forward.
He was right with what he said, it was intense. He was going slow, letting you adjust to the new feeling. You were loving every second and every inch.
You were trying to speak but you barely get out a syllable. Even these slow movements were giving you undeniable pleasure and already making the knot build up within you.
"You trying to say something baby shark?"
He cooed and pushed deeply, coming to a stop.
You panted and took a moment to collect yourself.
"I love it when your dominant and rough, Eijiro..."
He chuckled a little.
"You do?"
He bit your shoulder a little harder to leave a mark.
"Then beg me to rail you on this cock."
"E-eijiro!"
You moaned as he started to move again.
"You know I love it when you beg for it."
He moaned as he continued.
You were both silent for a moment, you couldn't speak. The only sounds in the room were your pants and the sound of your wet heat taking him so perfectly.
"H-harder Eijiro..."
You moaned a little louder and tried to roll your hips.
"Rail me, please!"
You begged and he pulled so far out you could barely feel the tip.
"As my baby wishes..."
He moaned loudly as he slammed back inside you and you let out a staggered high-pitched moan as your knot untied, your first orgasm rolling over you.
And then the extra intense part started.
He was hammering into you hard, you could hear the loud slapping of skin and the bed creaking beneath you both.
He kept an iron grip on you as he railed you up and down. His strength always amazed you but this was something else. Your body was already shaking as you hit another orgasm, your moans getting louder and louder.
This position was intense, it's like every single inch of you was being hit. It was making you so sensitive and sending you dizzy.
You came again, and again, and again. Your legs and body shaking and quivering while Kirishima never faltered, his rhythm perfect as he repeatedly slammed into you.
Your mind was fogged and overcome with pleasure as you lost count of the amount of times he made you cum.
"You like this baby?"
He moaned louder, he loved the sight of you coming undone.
"You like it when I rail you up and down on this cock?"
"YES!"
You moaned in response as yet another orgasm hit you.
You were so sensitive every movement felt like a spark of fire, it was intense and amazing and his thrusts were finally starting to lose his rhythm.
"FUCK!"
He was moaning loudly as he rammed into you.
"I-I'm gonna cum so hard!"
You moaned in response as you came undone for the last time and he slammed as deep as he could. You could feel him pulsing as he filled you up.
He grunted and rested his head against the back of your neck, slowly lowering your legs down. Your legs were weak and you fell back against his chest, your head resting on his shoulder.
You were both panting and breathing heavily as he wrapped his arms gently around you and kissed your cheek.
"I didn't hurt you did I?"
He asked quietly as he kissed your cheek again. As much as he loved to be rough, he was always worried he'd accidentally hurt you.
You shook your head.
"N-no..."
You turned your head to look at him.
"It was just... really intense."
You smiled up at him.
"I did tell you it would be."
He smiled back and tucked a lock of hair behind your ear.
"I'm probably going to need your help to move."
You giggled a little.
"In a minute, it's warm like this."
He playfully smiled.
"Eijiro..."
"Just a little longer?"
He kissed your nose and it made you giggle.
"Okay."
You smiled back.
You did enjoy the feeling of him inside you but you never thought he'd be into this, just having you sit there to keep him warm.
......
You stayed in his bed the entirety of the next day, you were happy it was a Saturday evening he decided to try the Unbreakable full nelson on you because you could barely move at all.
When he eventually lifted you off him and into the bed, you fell asleep almost as soon as your head hit the pillow. He just cuddled you from behind all night, gently stroking across your skin and just admiring your body as you slept next to him. And when you woke up, he made sure to bring you food and drink and also massaged your body.
He was the perfect mix of soft and rough and you loved it, he'd even put you in one of his shirts and your bed shorts so you didn't have to stay naked.
You rolled over and watched him at his desk, he didn't get to finish his work last night and spent most of today looking after you so he was doing it now.
You just smiled, wondering how events had managed to unfold so perfectly and make you this lucky.
......
"He must have done a number on you Saturday night huh?"
Helia nudged you as you, Mina and Helia walked to the gym for some evening training.
"You're loud most nights Y/N but that was something else. What did he do?"
Mina asked as you all entered the locker room.
"Nuh uh."
You replied as you got to your locker.
"You got your two tidbits of information before, not this time."
Helia just laughed as she started to get changed.
"Clearly Mr soft manly man is a freak in the sheets."
You just blushed as you took off your top to change into your hero clothes.
"And that proves my point."
Helia laughed while pointing to the bite mark on your shoulder.
"You should have seen Kirishima's back the other week."
Mina laughed and so did Helia.
"I knew Kaminari wasn't good enough."
Helia snorted as she finished changing and went into the gym in her hero outfit.
"I'm never going to hear the end of this am I?"
You asked Mina as you finished getting changed.
"Nope!"
Mina grinned as she headed into the gym, but she wasn't in her hero outfit.
As you opened the door, you spotted Bakugo and Kirishima working out near the back in their gym clothes. You followed the girls but made sure to keep an eye on Kirishima until you started working out. He was in some grey shorts and a black tank top, doing a work out with Bakugo.
He saw you looking and smiled at you as he kept going. You smiled back as you, Mina and Helia stopped.
"Alright Elementana, I've been gone for a while so lets see that improved quirk of yours."
Helia stretched and grinned as your head swung round to her from the use of your hero name.
That's when you noticed Mina was heading over to the mats with the boys while you and Helia were near the ring. It was a new addition to the UA Gym, a ring specifically designed for quirk sparring. It had a fence around it designed to try and keep quirks contained.
That explained why you were both in your hero clothes. You: a blue, yellow, white and green patterned V deep neck body suit with some red marks and red converse. Houndara: a Black hooded dress type top with fire patterns over it and black footless pants for her clawed feet.
"Alright then Houndara."
You smiled and used her hero name while entering the ring.
"Game on."
