it's not cheating if it doesnt go in... right?
cw: female!reader x bestfriend!roommate!satoru <3 implied satosugu, poor attempt at smut, dry humping, cheating but not really, kinda voyeurism??, just horny thoughts and horny stuff in general
playfighting with bestfriend!roommate!satoru clearly wasn't a good idea. you just know that you have absolutely no chance against those big, bulging biceps, rock hard pecs and abs and strong thighs of his. still, you like to push his buttons a little, blatantly cheating when you're competing against each other in whatever videogame he chooses and then saying that you'd never do something like that. that always ends up with a smirk on satoru's face, and you being pinned down underneath him and tickled almost to death in a matter of seconds.
usually his boyfriend, bestfriend!roommate!suguru would come to your rescue, just a simple "satoru~" in that sultry, sweet, but also warning tone of his could stop satoru just as fast as he started and make him apologize to you, with a kiss on the cheek and a little chuckle too.
this time tho, suguru is not here to rescue you. he's in the shower right now, while his stupidly hot boyfriend is quite literally torturing you. no amount of "satoru please, I'm sorry!" in between laughs, kicking or punching could move him from his solid position on top of you, quite literally straddling you while tickling not just your waist, but every part of you he can possibly reach.
satoru is grinning so so much, really doing his best not to look at how your shirt is slowly going higher and higher up your body revealing that you're not currently wearing a bra, and how perfect you look like this, all disheveled and breathless underneath him.
seeing him distracted for a second, you finally find the opening you've been waiting for, and switch positions with him with all the force you can muster. satoru is surprised to say the least, blinking repeatedly while staring up at you, all smiley and giggly. when he finally realizes that you're sitting exactly on top of his slowly hardening cock, he tries to play it off with a "getting stronger, aren't you sweetheart?" smirking non-chalantly, but the blush creeping up his neck is very much visible. he gulps loudly when you adjust yourself to sit better on top of him, he's even starting to think that you're doing this on purpose as your little revenge, but your sweet smile and innocent eyes prove him wrong. he should be feeling awful about how much he currently wants to just ruin you, tear off the poor excuse of a pajama you're wearing and make suguru think you're watching a horror movie from making you scream so loud.
key words: he should be feeling awful, but he doesn't. why? because as he sees you gasp at the realization that his cock is rock hard underneath you, he realizes that you want this just as much as he does.
that's why you glance quickly towards the bathroom door, making sure that the water is still running, before slooowly grinding on satoru, your shorts and his pants the only things in between your increasingly wet pussy and his concerningly long cock. biting your lip at the pressure, friction and pleasure running through your body, you don't even need to wait for a reaction or some sort of consent from him, as satoru's hands are quick to find your ass and make you grind on him again. his pupils are blown wide, his breath accelerated, he's never looked better.
"toru- w-what about sugu?" you manage to stutter as you grind on him just a bit faster, suddenly too aware of your own shorts now sticking uncomfortably to your most sensitive part because of how wet you are, and growing more and more frustrated at the amount clothing separating you from him. satoru lets a low moan slip past his rosy lips followed by a chuckle, and doesn't teally hesitate to say "it's not cheating if it doesn't go in baby, it's alright~ sugu will- fuck- will definitely understand~".
that's how you end up desperately dry humping him on the couch, tv long forgotten and still open on the game you were playing earlier.
both you and satoru try your best to keep your clothes on, to not cross the line... failing miserably. your shorts and his pants end up on the floor, and as soon as you start grinding again on his swollen, naked, hard cock you're a mess. with chills running all over your body and teary eyes, you just can't help but moan and claw at his chest every time his now pinky-red tip comes into contant with your sensitive clit.
satoru is totally convinced that he's in heaven, gripping your ass so tightly that you're sure he's gonna leave marks, and even giving it a slap because he just can't control himself. everytime his dick feels like is about to slip inside your hole he's rolling his eyes, numerous curses and praises slipping past his lips. "that's it- you're doing so- fuck- so good sweetheart. use me- rub that sweet pussy on me to make yourself feel good, just like that~" he groans, one of his hands now slipping under your shirt to grope at your tits and play with one of your nipples.
chasing your orgasm desperately, you pick up your pace even more, moaning loudly with some drool coming out the side of your mouth. "toru- feels so good- gonna cum!~" you whine almost pathetically, making him coo audibly. what makes you finally lose it is the feeling of his hand on your neck, pulling you down towards his face and kissing you oh so lewdly, all tongue, teeth and saliva. you respond to the kiss at the best of your abilities as you feel your eyes cross, your legs tremble and the most life-changing orgasm hit you like a truck. it doesn't take too long for satoru to reach his orgasm too, with the mess you're making on him, you soft lips on his and the sounds you're making more than enough to send him over the edge, moaning into the kiss and making a mess on his own abs.
slowing down the pace of your hips to come down from your high and panting loudly, both you and satoru are still buzzing. you keep your eyes closed as you softly rub your nose on his and peck his lips, gaining a soft smile from him as he kisses you back while keeping you as close to him as he physically can.
you both don't even realize that the shower stopped running long ago, and that suguru has been watching from almost the very beginning! <3 he was almost tempted to interrupt and join you two, but seeing his lover and his best friend, who he's had the biggest freaking crush on for the longest time, put on a show like that was simply divine. and even though his cock is so fucking hard and leaking even, he just silently goes to the kitchen to get you both some water, taking care of his beloveds being his top priority. but he just knows for sure that later he's gonna need another shower, and not alone this time <3
