the game between karasuno and aoba johsai was going to start in only fifteen minutes, but oikawa insisted that it would be fine if you snuck away with him for a little. you knew his intentions as soon as you felt his hand on the small of your back, but you went with him anyway. 

under the dingy light of the storage closet, oikawa was setting you on fire. brushing his hands against your bare waist. peeling off your clothes. kissing all over your neck and chest. you could hardly breathe after he sealed his lips over yours in a fit of passion, tongue slipping into your mouth like he knew it belonged there.

the tent in the setter’s pants was too noticeable to brush off. and, after all, he couldn’t be all pent-up during his game. (oh, you were so going to be in trouble for helping out the enemy.)

a few whiny pants fell from your lips before you suggested, “you’re so big. why don’t you just fuck me already?” 

“thought you’d never ask,” oikawa breathed out, voice low and husky in your ear. 

and that was how it began. 

you underestimated his power. oikawa was ruthless; fucking you like there was no tomorrow and drilling his cock into you so hard that you were seeing pinpricks of stars in the corners of your vision. meanwhile, his fingers were working in tight, small circles around your swollen clit, rousing sweet moans and whimpers from you.

“stay quiet, princess,” he growled. “you don’t want them to catch us, do you? if you know what’s best for you, then you’ll stay still and take it like a good little girl.” 

you mouthed an okay, but you couldn’t voice it. your brain was turning to mush, too hazy to think straight, too overcome by pleasure. all you could focus on was how oikawa’s cock was kissing your g-spot in the most perfect way. 

“t-tooru,” you whimpered out, eyes nearly rolling back in bliss. 

“did i fuck you stupid, angel?” oikawa asked, words burning into your skin despite how gentle he sounded. the ceaseless smirk on his face was making you go crazy. “fuck, you know how sick i am of seeing you being drooled over by those other guys? shitty losers. i need to mark you so that they fuck off.” 

your core was throbbing and clenching around oikawa’s cock as he littered hickeys on your neck. there was a wolfish look in his eyes, and you couldn’t even process how dangerous he looked because you were reaching your climax fast. 

before you could, however, oikawa shot his hot seed deep within you, making you glad you were on the pill. he let out a low groan against your sweat-beaded skin, breath hot and heavy. 

“g-gonna cum!” you whispered, burying your face into the crook of oikawa’s neck as your body convulsed. 

you succumbed to the tug of your orgasm, letting yourself get caught in the tidal wave of pleasure that washed over you. you fell in completely with a loud gasp, nails digging into the setter’s back as your legs shook and your pussy throbbed. the world fell apart around you until it was just you and oikawa, your body flush against his. oikawa clamped a hand around your mouth to silence your moans, which helped when you squirted over his cock. 

for a moment, you two just held each other and tried to catch your breaths. the game was about to start soon, though, so oikawa had to pull out of you and let go. 

with a cheeky grin, he asked, “round two if i win?” 

“if my team doesn’t kick your ass,” you fired back, folding your arms over your chest. 

“well, that’s impossible because—”

“oikawa tooru!” iwaizumi hajime’s voice boomed from outside. “where the hell are you?!” 

oikawa, startled for a second, looked over at you with a sheepish grin. he leaned over and pressed a chaste kiss to your lips.
