Immoral

Summary:

In where your boyfriend likes watching you get fucked, and you are a bit too late to tell him that maybe it’s a bad idea.

Work Text:

The first time was a once-off, you’d thought. You had been clingy all day, and your boyfriend had been so tired from practice. So he asked someone to help out for you, and that’d been that. No big deal. You’d been a bit surprised that of all people, he’d asked Miya Atsumu to do the job, but considering the setter’s long fingers had soon been stuffed deep into you it didn’t occupy your thoughts much. You’d all be going your separate ways anyways, you and your boyfriend back to your apartment, and Atsumu would stay in his own little world far enough away.

So when not three days later Atsumu was seated on your couch with a brilliant smile on his face, right opposite your significant other, it’d made you a bit cautious. From as soon as he’d gotten comfortable around you, Kiyoomi had liked prodding at your boundaries. Reaching at but never past ‘em. It made intimacy fun, made your heart beat and so you’d always been pretty open with his suggestions. But this had been difficult to grasp. “I want to try something new. I think you should let him fuck you,” he’d said, and you’d been able to close your gaping mouth just long enough to catch the intrigue in Atsumu’s eyes.

 

“W-What? But what about you, Omi?”

“I want to watch. If you’re comfortable with that. I think you’ll like it.”

Looking back, you had liked it. It made you feel desired, hot and flushed and it didn’t hurt that compared to your boyfriend, the blond loved showering you in endless praise. Telling you how pretty you were, how sexy your sounds and how great your touch. You had liked it once and twice, and with that, had learned to like his attention too. Slight touches brushing past your hand in public just made you feel like you had a secret of you three. But maybe you should’ve talked about it with Kiyoomi more than you did. Atsumu fucked you in front of your boyfriend more than he did himself after a while, and you started missing his touch. Any time you’d initiate something, he’d tell you to shower, and by the time you came out of the hot water Atsumu would be at the door to help you out.

“Yer a bit touch starved, aren’t cha? Pretty girl,” he’d whisper, pressing kisses to your crown when drawing you close. “I’ll make ya feel good, baby.” The more Atsumu came over, the less touchy Kiyoomi grew. But in daily life, he was the same man you’d fallen in love with, which made it so much harder to complain about the strange dynamic. He wasn’t touching you, but he seemed happy to stay on the sidelines and watch. And you were getting all the sex you could ever need, even if it wasn’t with your boyfriend. Maybe you should’ve talked about it more, but you’d been thrown into the dark so suddenly that it felt easy to cling to the strong arms wrapped around you every other day.

“Keep yer eyes right here, baby girl,” the lithe voice calls, fingers under your chin and aiming your face up. Atsumu hovers over you, pressing you back into the plush of the bed with his weight supported on his forearms. He presses a few kisses to your lips, giggling when you whine at his slow movements, before he trails his fingers down your naked chest and over your nipples. He’d been at this for quite a while, and you are definitely growing more impatient by the second. When you reach up to wrap your arms around his neck with another whimper, he tutts his lips. “Shh, pretty thing. Play nice.” He flicks his finger against your pointed bud as a punishment, before continuing his slow, meticulous movements a bit longer.

But you can tell even he’s getting testy. His fingers keep going back and forth between messing with your lips, your tits and your drenched panties, as if he can’t decide which of his toys to play with first. He smacks his lips before dropping his mouth to the swell of your breasts, starting to mark you up in the places the bruises of previous nights aren’t scattered. The warmth of his mouth leaving more obnoxious blots of color. Atsumu lifts his face from your skin for long enough to settle back between your legs, rutting his hardness against you with slow drags of his hips. “Stick yer tongue out for me,” he breathes, and as soon as you do he pinches it between his fingers to tug. “I’ll get ya nice and messy for me, don’tcha worry. Would’ya like that?” With your tongue still held out of your mouth, he peers down at you with those pretty browns for an answer.

Saliva builds up in your mouth as you breathe out, humming in reply. Always concerned about your pleasure first, he rolls his hips into yours harder. “Good.” He leans down to press a kiss on your tip of your tongue, and as messy and overly intimate as it is, you’ve long grown appreciative of all of it. Even if it makes you feel dirty, you savour the feeling. You’re more than happy to take it all if that means you’re being touched. You let your eyes drop closed when he lets go of your tongue, leaving it out still. Spit’s collecting in your mouth and going down your face, and the blond grunts like it’s the best sight he’s had in a while. “Keep it out, good girl.” He leans down to you again to lick up the length of your tongue, before he sucks on the wet muscle, moaning.

While he traces your tongue with his, his hands grab at your ass to drag you into him more, and you grind back on his slow motions to the best of your ability. His hard cock pushing exactly where you need it to, though you’d love it even more if he just gave up and fucked you already. Alas. When he pulls back to let you breathe, you frown at him and try to speak without disobeying his order. You compromise by pulling your tongue back but keeping your mouth mostly open. “You’re so nasty, ‘Tsumu,” you manage to mumble, swallowing some of your spit before you make more of a mess of yourself.

Atsumu just laughs, a soft, breathy one, burying his face into your neck. “Yer one to talk. Droolin’ all over yer own face.” He presses wet kisses to the expanse of your neck in between the words, leaning up to wipe some of the spit on your chin away with a thumb. “But ya look so pretty like that, ya know I can’t help myself.” He slowly pushes your tongue back into your mouth with one finger. Then he slides his hand back down your body to rub over your covered slit and to give a mind-numbing pressure on your clit. You groan at the feeling, both at his calloused fingers being used so well and at the way your wet panties feel on your skin. He’s quick to silence your noises with a proper kiss, lazy pulls of his tongue around yours and his lips melting to you in a perfect rhythm to drive you crazy. It still surprises you, how good his is with that loud mouth of his.

A soft click sounds through the room. You don’t have to look to know that your boyfriend is freshly showered, and will take his seat in the chair positioned right next to the window soon. Atsumu doesn’t allow you to tense up though, pulling back from your body to start shimmying your panties down your thighs. “Finally. Poor thing’s been wet for fifteen minutes.” You would’ve been able to start much sooner if he hadn’t insisted on a rule that you can only have sex from the moment the spiker is in the room, and not a second earlier. Hell, you would’ve been able to start much sooner if he didn’t want to watch you get fucked more than he wants to do it himself. 

Kiyoomi gives only a soft sigh in response as he plops down in the chair, springs creaking. You open your eyes and are met with Atsumu’s adoring gaze, one which he keeps as he taps the sides of your hips. “Lift ‘em, please.” He takes off your panties and tosses them at the foot of your bed, before he finally uses those pretty hands on your dripping slit, working you perfectly. He swirls around your clit for a moment, dragging two digits up and down to slick them up and you’re already so worked up from all the teasing that this makes you shudder. He always is a dream when he gets to put his hands on you. His tongue peeks out between his lips when he glances between your bodies, focussing on every twitch and tug. He’s so pretty.

You take a moment to glance away though, meeting Kiyoomi’s calculated expression. His dark hair still damp, shirtless and slouched into the red chair, he regards you. His stare is blank. You can’t remember the last time he looked at you with genuine lust, but then again, you’re not sure he ever actually did. Even so it’s been months, you can barely remember what his touch feels like. The tenseness of dredging through the thick tar of your thoughts must follow through into your body, because Atsumu looks back up at you with a slight frown on his handsome face. “You okay?” You nod right when he slips in a finger and kisses you on the temple. “Yer so tense, baby girl.” The faint kisses down your neck and collarbones feel like heaven. 

He rubs his thumb over your sensitive clit as he sucks and bites at both nipples. His long fingers curl inside you just right as soon as he adds a second and a third one, stretching you out. His fingers are so thick and strong, able to hit the right spot inside you every pump. And the added feeling of his breath on your wet chest, the weight of his body on you. You whine out his name, tangling your fingers in his hair as your back curls off the mattress. Atsumu grins, even with shut eyes you can hear it in his voice and you call for him again, the coil in your belly already winding tight. “Feels good?” he asks, giggling when you nod your head up and down without thinking. Yes, yes, he feels so good. He always does.

 

Your legs are spread wide apart, thighs trembling the longer his brutal pace continues on your body. “Ah— ‘Tsumu, I’m close.” Beads of sweat pool under your breasts, and you open your eyes long enough to catch the look on his face. There’s nothing there but devotion to bringing you pleasure. You couldn’t believe it when he fingered you the first time, and it’s still hard to believe now. Your body shudders at the sight. His thumb gives a particularly hard few circles on your clit, making your head spin. And his other hand is pinching at your tits, using his nail to flick over the peaked knob. It’s rough, but so good. “Uh, oh- p-please Atsumu,” you ramble, “‘Tsumu, wan’ cum. Wanna cum, please. Please.”

The squelching of your sloppy pussy fills the room, as Atsumu groans. “Yeah? Yer gonna cum all over my hand, huh?” The deep tremble of his voice feels deafening, you’re so close it’s almost painful. You pull him closer, wanting to feel him, his warmth, the smoothness of his skin, anything at all— 

“Let her cum on your cock,” Kiyoomi orders, drawing your attention over. He has his hand wrapped around his cock, lubed up with lotion and jerking his wrist to slide over the pretty, pink head. The time you were allowed to do it for him seems distant. At the soft moan he lets out you fight the urge to call out his name, because that too isn’t allowed anymore. Something about breaking the immersion. You can’t help but think anyone would be hurt that the sound of your voice bothers him when he’s jacking off. Maybe you just sound gross— no, Atsumu loves hearing you. He could get off on your noises alone. And turning back to find reassurance in the man nestled tight between your legs becomes easier each time it happens.

You hold the immensely frustrated pleads that work up your throat to bite your bottom lip, instead just going along with it. There was a time where you’d have pleaded to let you cum, a time where he’d have his own fingers on and in you, where your begging actually meant something. But you know by now that the more you talk back, the less Kiyoomi allows you to receive. The blond seems almost as angry at the denial of your orgasm as you are, because the slight twitch of his brow stays. But as he stills his fingers, he curls them obscenely once more and presses his lips to yours. “Sorry princess, ya heard the man.” He then pulls the digits out of you to slip them into his own mouth, cleaning your juices from them with a lewd ‘pop’. He shoves his boxers down his thick thighs to expose himself, giving himself a quick few pumps.

“Bend back yer legs for me, pretty girl. I’ll make it up to ya.” He helps you lift your knees to your chest and runs the flushed, leaking head of his cock up your slit until he’s as wet as you are. Then he presses another kiss to your parted lips, and smiles into it. He pulls back with a low whisper, slowly starting to push in as he pushes out the words. “I love stuffing this pretty cunt. It’s mine.” The stretch feels so good, so so good and he’s so warm, you mewl as he sinks into you. And as you reach one hand back up to his shoulders to steady yourself on his big cock, the other searches out his touch. His long fingers tangle easily with yours, slotting perfectly together.

“Ahgh,” you moan at his first thrust, “so full. S’big, ‘Tsumu.” He leaves kisses all over your face as you get used to the overwhelming feeling of his cock, and you glance over for just a moment to the chair. Kiyoomi is dabbing at himself with tissues. You didn’t even notice he already came. You want to feel bad, you should have noticed, you should have— But then Atsumu switches out the slow draw of his hips for a faster rhythm and you’re gone from the world. You babble out his name and cling to him as the orgasm that was so cruelly denied earlier builds back to a peak, the heat in the pit of your stomach overflowing. “Oh fuck, oh fuck, oh fuck, ohfuckohfuckohfuck, Atsumu!” Your legs tremble, your walls squeezing around him so hard he can barely pull himself out enough to thrust. Black and white marks the edges of your vision.

 

You’re still far off from the world when you feel the setter’s lips on yours, but the vague words from your side filter in not too much later. Your boyfriend clicking his tongue. “You’re such a filthy slut, cumming all over someone who’s not even your boyfriend. You just need any dick to get off, tch.” You come down after that, feeling too hot but slightly cold as well. Atsumu pulls his hips back far enough to allow you a moment more to get back to yourself, before he touches your chin to draw your face back to his.

“Can ya do another, baby? I wanna give ya another.” It’s sweet. He’s sweet. You nod. So ever so slowly he starts back up, giving your sensitive body extra attention. You bury your face into his neck as he hovers himself back over you, his chest heaving up and down from the effort. “Yer so pretty. So good, so tight for me. Always so fucking tight for me.” You plant kisses there until Atsumu starts groaning out his words, your name over and over and you forget about the stinging gaze on the both of you. Maybe you should have talked about this with Kiyoomi more. No, you definitely should have. Then you wouldn’t be falling so hard for the guy your boyfriend brings in to fuck you when he can’t be bothered.
