🔞 impact play, t/b dynamics but it’s atsumu slapping kiyoomi during missionary, telling him to do better. if anything, it only makes kiyoomi go sloppy with each of his thrusts, whining and so turned on by how it stings. or—

it’s kiyoomi getting slapped while atsumu rides him, degrading kiyoomi with mentions of him being on top and doing all the work, how kiyoomi is a “useless top,”

atsumu and kiyoomi always sitting together just to atsumu can lay one of his thighs on top of one of kiyoomi’s own. and kiyoomi absentmindedly forming this habit of squeezing or running his hand on atsumu’s thighs from time-to-time.

🔞 atsumu thought that breaking the bed after a not-so-few rounds would be the end of their steamy honeymoon night, so he expect aftercare. that is until his newlywed-husband lifts him up, carefully lays him on the rug of their hotelroom floor,

continuesly planting kisses on his bare skin as kiyoomi adjusts him to a new position. “sorry atsu, you know as that i hold utmost respect for you, baby. it just might not seem like it for the rest of the night.” kiyoomi says, breathless,

🔞 kiyoomi like this after his first with atsumu. he’s all clingy after, keeping his body close to atsumu’s and making sure they’re locked in each other’s arms. “did i do well, atsu?” kiyoomi asks before pulling out of atsumu while planting a kiss on the latter’s hand.

🔞? kiyoomi and atsumu who found themselves in some unspoken situation. to an extent, their relationship would be nothing more but teammates—friends at best. or that’s what it should be.

they never really expected that they’d find their selves in some fucked up, freak relationship. sending nudes to each other after a long day of practice, sometimes just randomly, or when one notices that the other’s obvious pent up frustration. it just kind of started,

like that man cannot control himself with atsumu. atsumu’s clothed ass is brushing on his hard-on and he feels himself twitch and ache, feeling a knot on his stomach form. he’s making out with atsumu, the latter on his lap, and they both feel kiyoomi’s pants stain with cum.

🔞 like kiyoomi’s balls deep inside atsumu, and atsumu—with all his remaining strength and pride—shamelessly runs his mouth and fucks with kiyoomi. god, atsumu swears he can feel kiyoomi twitch inside of him before kiyoomi fastens his pace, feeling all rough and needy for more.

one sakuatsu headcanon that i love would be that bickering turns them on, and that they’d bicker during a sex.
