Chapter Text
(Y/N) walked through the hallway, muttering to herself as she scribbled in her notebook, " And if this happened then Kirishima would " Bakugo snatched her notebook, A shit eating grin painted on his face. " Whatcha writing? " Bakugo questioned, his grin becoming wider when he saw (Y/N)'s face reddened.
" I'm not writing anything! Give my notebook back Bakuhoe! " (Y/N) yelled, attempting to grab her notebook from the Ash Blonde. " Mmm No " Bakugo sneered. " Don't be a dick you dick " grumbling, (Y/N) kicked Bakugo in the toe, successfully grabbing her notebook. " Whatever, also. " Bakugo's brows furrowed, his face seeming to have turned serious. " Don't go to Kirishimas room, he's sick. "
" Well why can't I just take care if him? "
" its something you can't take care of "
" Mhm yeah yeah Whatever "
Turning a sharp corner, (Y/N) arrived at the kitchen. Making her way to the fridge, she got raw seasoned steak. " Kiri's a shark, he can eat this raw right? " (Y/N) muttered, shaking her head, she grabbed a pan and began to cook.

Humming, (Y/N) held a cooked steak, strolling to Kirishimas room. Knocking on the door, she heard nothing. Strange.. Normally Kirishima answers quickly. (Y/N)'s thoughts got cut off when she heard a door knob turning. Rubbing his eyes, Kirishima opened the door, his gaze traveling her up n down with a confused gaze. " Bakugo told me you weren't feeling well so I brought you steak! " (Y/N) chuckled, handing the steak to Kirishima. " Oh, uh Thank you (Y/N) but you didn't have to " Kirishima took the steak with one hand, while the other scratched the back of his head. " Oh I know! But I wanted to " (Y/N) wiggled her eyebrows playfully, chuckling when she saw Kirishima stiffening. Waving, she turned to leave. Kirishima quickly grabbed her wrist, his face red with blush. (Y/N) looked at Kirishima, her head tilted with a brow arched. " Thank you, (Y/N), can you return later so I can actually thank you..? " Kirishima smiled, his breathing becoming uneven as his face reddened even more. " Of course! Anything for you big red " (Y/N) Purred, winking at him when she skipped down the hall. Kirishima sighed, looking down at the steak and licking his lips. " She's probably gonna taste better.. "

Knocking Kirishimas door, (Y/N) stood there, waiting patiently. Smiling, she watched the door open to see a flustered Kirishima. " Hey big red! " (Y/N) chirped, hugging Kirishima as he smiled. Blushing brightly, Kirishima held onto (Y/N) tightly as he walked into his room, shutting and licking the door behind them.
" Hm? " (Y/N) peaked at the door then at Kirishima, shrugging her shoulders (Y/N) smiled. Panting, Kirishima held (Y/N) tighter, sniffing her neck as she shivered. " Kiri are you okay? " (Y/N) questioned, pulling away as a worried look painted her face. " I - I need your help.. " Kirishima muttered shyly, slowly pointing down to his pants. Her gaze traveled down and landed on a growing bulge, her eyes widening as her face reddened.
" I- "
" You don't have to help if you don't want to. I'm sorry I asked, its just its Shark week for me which means I'm in Rut and you smelled so good and I can't help myself and I- " Kirishima babbled, but was cut off as (Y/N) crashed her lips on his, softly nibbling at his lower lip. Pulling away, (Y/N) smiled, " Don't worry big red, I'll take care of you. " Kirishimas eyes glazed over with lust as he pushed (Y/N) onto his bed, panting heavily as he crawled on top of her and nipped at her collar bone.
" hah.. Kirishima " (Y/N) mewled, her legs wrapping around him as as he suckled on her neck. Kirishima smirked as he pulled her shirt off, admiring your body as his hands made way to your pants.
" You're so beautiful.. " He muttered, pulling her pants off. Blushing, (Y/N) pulled Kirishimas shirt off, outlining his abs as he let out a whine. Panting heavily, Kirishima grinded against (Y/N)'s core, earning a mewl from her.
" P - Please.. " (Y/N) whimpered, bucking her hips against the red heads bulge. Smirking, Kirishima pulled his pants down along with his underwear. (Y/N)'s breath hitched. Staring at the member, its head seemed to habe been blushing too. Kirishima whined, his head buried in the crook of (Y/N)'s neck as she slowly began to use his precum as lube.
Pushing her underwear aside, Kirishima slowly pushed his member into (Y/N)'s core, moaning softly as he nipped at her neck. (Y/N) groaned, her nails scratched the Sharks back as his tail swayed. Panting heavily, Kirishima began a slow pace, groaning as he felt (Y/N)'s core tighten around him. " You're so perfect.. Ah~ " Kirishima whispered in her ear, his pace seeming to pick up. Mewling, (Y/N) began to feel the knot in her stomach, but it was far.
" .. F - Faster.. please!.. " (Y/N) whimpered, moaning as Kirishima picked up his pace.
Groaning, Kirishima felt his knot begin to swell. Biting onto (Y/N)'s shoulder, his thrusts quickened. (Y/N) let out a cry, her legs tightening around Kirishimas waist as the knot in her stomach begin to snap.
" Hah!~ K - Kirishima! " (Y/N) cried, her legs shaking as she tightened around Kirishimas member. Biting deeply onto (Y/N)'s shoulder, Kirishima moaned as he buried his knot deep in (Y/N), his cum painting her womb white.

Panting, Kirishima pulled out, laying next to (Y/N) as she breathed heavily. " Thank you for helping me. " Kirishima smiled softly, hugging (Y/N) as she drifted off to sleep.
