“Mornin’ babe…” you mumble into the sheets, arm reaching out to drape over the body lying next to you.
You’re greeted with a rough American accent, grumbling about it being too early to wake up, before you’re pulled close and two thick arms wrap around you, effectively crushing you against Marc’s chest.
You wiggle around in his hold just enough to free your arms and bring them to his back, rubbing at the tense muscles there. Marc relaxes a bit, moving to rest his head in the nook of your shoulder. You continue kneading the muscles on his back, his shoulders, slowly moving lower until your fingers are pressing into his lower back.
You trace idle patterns on the skin there, ever so slightly dipping your fingers into the waistband of his black boxers before-
“Fucking hell [Y/N]-“ Marc groans, scraping his teeth against your shoulder as you grab his ass under his boxers, squeezing his cheeks and humming at how round and full they feel in your hands.
What a lovely start to the morning.
Steven drops a pinch of fish food into the fish tank, talking to the little goldfish (Gus 2.0 and their new addition, Goldie) and occasionally Marc. It seemed like he had more control of the body today, and he’d decided to go about sorting through his books and cleaning up the place a little.
You were working on one of your projects, putting together some documents, looking up every once in a while, to watch Steven go about his day, mumbling under his breath as he marked sections in different books. It brought a smile to your face, seeing them happy, seeing Steven and Marc at ease now that they were free from being Khonshu’s avatar.
Steven moved around the apartment, crossing over to the kitchen to grab a snack and as he made his way back to his desk, your hand shot out and smacked his ass, the resounding clap drowning out Steven’s cute little gasp.
“W-what was that for?” he exclaimed, turning to face you with wide eyes. His cheeks were flaming red and he squirmed as your hand groped his ass cheek before you moved it up to grab his hip and pull him close to you. You looked up from your laptop screen with a mischievous smile, chuckling as Steven rolled his eyes. You tilt you head up a little more, puckering your lips in a silent request, and Steven smiles as he leans down and pecks you softly. You try to deepen the kiss but he pulls aways and fixes you with a look.
“Don’t you have work to do?”
“Ugh, yeah, but it’s boring!” you groan. “I’d much rather be doing you,” you say, waggling your eyebrows.
Steven blinks, before erupting into laughter. He’s leaning against you now, and his voice quiets down a little. He mumbles under his breath and you hold him as you watch his head droop a little. A few seconds pass before his head shoots back up and you’re now faced with Marc, who’s staring at you with a raised eyebrow.
“That was so fucking bad [Y/N].”
“Yeah well, it’s the truth,” you say, before you both laugh, holding each other’s hands and squeezing them slightly.
You really love working at home.
“Oh, hiya love!” Steven greets you as you walk into your apartment, waving excitedly from his spot on the bed, where he’d been reading.
“Hey…” you groan out, feeling the energy seep out of your bones the second you cross the threshold and drop your bag onto the couch.
It had been quite a tiring day at work, what with a new client dropping a project out of nowhere, leaving your department scrambling to make up for the loss. You’d already spent a sizeable amount of the assigned budget for this new project and to have them come out of nowhere and say they didn’t want to continue the project anymore was frustrating as hell.
Steven peered at you with concerned eyes as you slowly peeled off your coat and stripped down to your underwear before walking into the shower, shoulders slumped and head hanging low.
Yeah, we gotta do something.
The two make their way into the bathroom, which was filled with steam. You were in the shower, hands braced against the wall as you let the hot water from the showerhead fall over you, the heat soothing your aching muscles a bit. At the sound of the bathroom door closing shut, you look up to see Steven undress, before squeezing himself into the shower and standing behind you, his hands settling on your hips to steady himself.
“Hi sweetheart…” he sighs, kissing the back of your neck and lightly massaging your hips. “Bad day at work?”
You scoff. “Yeah, just an all-round mess.” You turn around to face Steven before dropping your head down against his chest. The hot water rained down over the both of you, and you felt Steven move a little to grab the body wash, before lathering it up in his hands and scrubbing your back.
While his hands worked on cleaning you up, yours slowly crept down his back and over his ass, your fingers digging into the round cheeks. You lifted your head up and onto his shoulder, looking down at your own hands as they squeezed.
You could hear Steven panting, his warm breath washing over the skin of your shoulder. One of your fingers dips into the space between his ass cheeks, sliding over his puckered rim, which clenched slightly.
“Can I fuck you?” you whispered, your voice cracking slightly. “In here? Don’t wanna move to-“
“Gods yes, please-“ Steven groans, moving to kiss you, while you blindly reach over to grab the lube that Marc had decided to stash in the bathroom when he’d gotten a little too impatient that one time.
Neither of you was in any mood to draw this out. You were tired from your long day at work and Steven and Marc had already had their own little fun time when you’d been at work, so neither of you was going to last long.
You had Steven leaning against the shower wall, his back pressed against the wet tile and one of his feet resting against the little ledge on the side as you fingered him. One of his hands was moving furiously over his cock, while the other was situated between your legs. His fingers rubbed at your clit, the water and lube making everything so slippery but feel oh-so-good.
You curled the fingers inside him, trying to find that spot inside him that made him sing, and it didn’t take long until your fingers were pressing right over that bundle of nerves, over and over, meanwhile, Steven’s fingers continued laving attention on your pussy, switching between rubbing circles around your clit and dipping into you, feeling how wet you were.
You were vaguely aware of just how depraved it all sounded, your moans echoing in the shower, the slick sounds of your fingers in Steven, his fingers inside you, his hand moving over his cock, the occasional sound of skin slapping together, all made louder due to the water that dripped down on them.
It didn’t take long for Steven to spill onto his own hand, cum dribbling down, some of it getting washed down the drain. You weren’t that far behind, tensing as you felt your orgasm wash over you. You come around Steven’s fingers, clenching rhythmically around them, and even after you come down from your high, his fingers continue to move inside you, feeling the wetness, before bringing his fingers up to his mouth and licking them clean.
You moan, slipping your fingers out of him and kneeling in front of him, licking at the remnants of his spend that dripped down his cock and his thighs, before reaching back to squeeze his ass again.
“Your ass just made my day less sucky.”
Steven shook his head and laughed, before helping you back up on your feet. He spent the next few minutes cleaning the two of you up, relaying messages to and from Marc, while you vented about your day.
Eventually, you moved to the bed, where you snuggled close to Marc, who’d fronted at some point between your walk to the bedroom. He wrapped himself around you, letting his weight press you down against the bed just the way you liked it, and pretty soon, you were fast asleep, one arm spread out beside you, while the other stayed wrapped around Marc as your hand stayed on his ass.
You really loved that ass.
“Oh fuck, Marc, please- oh my god-“
You craned your neck down to see Marc resurface from his spot between your legs, his lips and chin glistening. He smirked as one of his hands reached up to intertwine your fingers together, before dropping his head back down to lick at you core, his tongue moving all over you.
Your free hand moved towards his head, your fingers grabbing his curls in what must have been a painful grip, as Marc ate you out. The sounds that filled the air were absolutely obscene as he swirled his tongue around your clit before sucking your pussy lips into his mouth, making your back arch off the desk that he’d pushed you on top of earlier.
You were in one of the empty conference rooms in your office. It was after work hours, so the only people in the building were the night guards and a few people that worked for the other companies that shared the building. When you’d told Marc that you had to stay back at work to finish up some stuff, and that everyone else had left, he’d wasted no time in showing up under the pretense of accompanying you back home so you wouldn’t have to be alone so late at night.
That had been an hour ago. He’d watched you work for a bit, sorting through some files and what not, and when you’d announced that you were done and ready to leave, he’d stalked over to you with that smirk of his and pulled you into the closest conference room, before pushing you down onto the table and pulling off your slacks and your panties along with them.
“Marc…” you whimper, the grip you have on his hair tightening as he smiles against your core. You want to tell him you want him, that you need him to fuck you, but it’s getting harder to form words in your mouth and all you can do is moan and squeeze your thighs around his head.
After what seemed like hours but could only have been a few minutes, Marc stands back up on his feet, his hands dragging up over your legs and thighs, squeezing them lightly as he moves to stand between your hips. You can see the clear outline of his hard cock straining against his jeans, and before you can focus on anything else, he’s unbuckling his belt and pushing his pants down just enough to free that giant cock.
Marc looked like a mess, his hair standing up from the way you’d grabbed it earlier, and his face was flushed red and wet from the nose down. He looked so fucking sexy it made you want to scream. He grabbed the back of your thighs and pulled you closer to the edge of the table, before licking his fingers and rubbing your pussy, making sure you were still wet enough to take him.
You hooked your legs around his hips as he slowly pushed into you, his cock stretching you out and filling you up, making you quiver and moan out loud. Marc licked his lips, before grabbing your hips and thrusting deep into you, smiling with satisfaction as he watched you grip the edge of the table.
Everything was a blur after that. Marc set a punishing pace as he fucked you hard and deep, making you clench around his cock. At some point he’d pushed your shirt and bra up to expose your breasts, and he’d taken the time to leave hickies all over them, biting and sucking at the skin harshly before soothing it with gentle licks.
You mouthed at his neck, biting at the thick vein as he continued fucking into you, when you felt his head drop against your shoulder. His hips continued thrusting back and forth, stuttering every now and then when you clenched around him.
“Bloody hell, I can’t believe we’re doing this at your work, this is insane,” Steven whispered right against your ear, before standing up straight, pulling you up with him. Your hands instantly moved into his pants and grabbed his ass, urging him to thrust deeper into you, licking up his neck and sucking on the spot behind his ear that you know will get him to move faster.
“Steven, fuck- oh, right there, baby, please- where’s- where’s Marc?”
They sounded drowsy and you feel their hips falter against yours, slowing down and speeding up at random. Steven and Marc were both trying to chase down their orgasm, and you were holding on for dear life, your nails digging into the skin of his ass cheeks. You were so fucking close, but it still wasn’t enough, so you keep grinding your hips against theirs until-
“I’m cumming- oh my fucking god- fuck-“ you scream, feet digging into Steven and Marc’s lower back, holding them in place as you gush around their cock. You slumped against the body holding you close, arms wrapped tight around you as the cock inside you pulsed, and suddenly you were being filled with thick, hot cum.
“Fuck that was good…” Marc whispered as his hips stuttered, and you both feel the cum inside you leaking out from where you’re still joined.
You stay like that for a bit, foreheads pressed together as you come down from the high of your shared orgasm. A quick look to the left has you gasping because good lord, it was so late and you still had work tomorrow.
“Not without cleaning up!” Steven exclaimed, pointing at the mess on the table and down on the tiled floor.
You make quick work of cleaning yourselves (and the office, which you make sure to lock up) before quietly leaving, your hand in Steven’s back pocket, and his arm slung around your shoulder as you walk out the front door, avoiding the gaze of the nightguards.
“We…we actually shagged in your office-“ Steven whispered excitedly. “That was-“
“Fucking awesome, I know,” you say with a toothy smile as you pat his ass. “Next time, bring a condom so we can avoid the mess.”
“Oh hell yeah,” Marc whispered, leaning over to kiss you, biting your lip lightly, like a promise.
“Next time?” Steven looked scandalized, like he hadn’t just had semi-public sex a few minutes ago.
“You know what? Maybe next time we should hit the museum. Steven, you know any good spots in there where we could fuck?”
You giggle as Marc and Steven bicker back and forth, Steven appalled at the possibility of being caught and being fired again and Marc having fun teasing their shy, adorable boyfriend.
These boys were going to be the death of you.
You loved the weekends. Two whole days where you and your boyfriends got to just kick back and relax, catch up on some TV shows, lounge around in your underwear, and just enjoy each other’s’ company.
You find every opportunity you can to smack that delicious round ass of theirs, watching it jiggle, delighting in the way Steven gasps and blushes, or the way Marc leans in to the touch, grunting softly before pulling you towards him and kissing you.
Sometimes you’ll sidle up behind them and grind your hips against their ass, and Marc or Steven will whisper ever so softly if you could fuck them, and you pretty much live for those moments.
So here you are now, kneeling on the bed facing Steven, who’s laying face down on the bed with his ass high in the air while you finger him open, watching the way his hole stretches around your fingers. You’re already strapped up, the harness digging ever-so-slightly into your hips and the big, veiny dildo hanging from the front, which you grind against Steven, watching his skin erupt in goosebumps.
You continue fingering him, listening to him groan against the sheets as he fists them. From time-to-time, you hear Marc’s moans mixed in there too, telling you to hurry up and just put it in already.
You opt to ignore his urges, because the dildo is a little big and even though they’d used it before, you don’t want to risk hurting them, so you take your time stretching them out.
“[Y/N], please…” Steven whispered so sweetly, turning his head slightly to look at you with those pleading eyes and who were you to deny him anything?
Your pull your fingers out of his hole, before quickly applying a generous amount of lube over the dildo. You lean closer towards Steven, rubbing the lubed-up dildo against his hole, watching it clench around nothing.
“Hey babe? I wanna try something…” you hum, pushing the head of the dildo into his hole slowly and watching it stretch around the formidable girth.
“What- fuck, what did you have in mind?”
“Wanna see if you can come with just this. You think you can do that?”
“[Y/N]…” Steven groaned, feeling the head of the dildo push into him fully, waiting for the rest of it to fill his insides.
You lick your lips, feeling the temperature around you rise a little. “You didn’t answer the question baby.”
“I’ll try, please- please just fuck me.”
“Alright darling, I got you.”
You slowly thrust into him, watching the rest of the dildo disappear into him, and you both groan as you bottom out, your hips pressed flush against his ass.
“Remember, you can’t touch your cock yeah? Want to make you cum just using your ass.”
“Good lord [Y/N], please-“
And without much warning, you pull almost all the way back before thrusting back into him. Your thrusts are pretty hard and deep and you relish in the way Steven’s ass jiggles when your hips smack against him at every thrust.
You really, really, love that ass.
Seemingly on autopilot, you bring a palm up to your mouth, licking it, before raising it up over Steven’s ass, and smacking it down onto his right ass cheek, hard, watching the skin redden.
You still for a moment, keeping an eye out for Steven’s reaction, but it turns out you don’t have much to worry about because he moans really loud, his back dipping even lower down onto the bed.
“Oh gods, do that again, please-“
“Fuck, you like that baby?” you ask, fucking him with shallow thrusts as you grope his ass. You watch him nod against the sheets, and so you decide to give him what he wants.
With every few thrusts of your strap-on pressed into him, you’d raise you arm and smack him on his ass, alternating between hitting his right and left ass cheek. You switch from deep, hard thrusts to fast, shallow ones, hoping to find his prostate, and when you did, Steven cried out, thrusting his hips back against you and sobbing as he urged you to go faster.
You could tell he was close, and a quick look down at the sheets between his legs confirmed it. His cock had leaked profusely down onto the sheets, leaving a giant stain of precum. And all without touching his cock.
“You close?” you mumbled, biting your lip as you tried to keep up a consistent pace, but watching Steven fall apart, all because of you had you feeling light-headed.
Marc was the one who answered. “Yeah- fuck, we are, keep going, please- [Y/N], please-“
His words were a little slurred, and you hear Steven chiming in, adding his own set of pleas, so you fuck into them, sweat dripping from your forehead at the exertion. It’s like you’ve got tunnel vision, the only thing that mattered in that moment was giving your boyfriends what they wanted, you wanted to make them feel good, you loved that you could make them come undone, and one a particularly hard thrust, you raise both your palms, licking them to make them wet and cool, before smacking their ass cheeks in succession, left, right, left, watching the skin flush red, and before you know it, they’re coming, groaning out profanities, still pushing back against the strap-on as they chase their orgasm.
You watch them with amusement, wiping the sweat from your forehead and pushing back the hair that had fallen over your eyes. Steven had slumped down onto the bed, wincing when he felt his precum smear against his stomach. The dildo had slipped out from him, making a squelching noise from all the lube.
You straddle the back of his legs and spread his ass cheeks, watching his gaping hole try and clench around the air, and because you were a little tease, you dipped two fingers in, thrusting in and out slowly just to watch him squirm from the overstimulation.
And just for good measure, you smack his ass again, before bending down to press a few quick kisses to the red skin, feeling the warmth, and you snicker as a weak moan reaches your ear.
“I get it, you love my arse,” Steven grumbles, drowsiness evident in his voice.
i tried to be a little more accurate with the DID representation, consulted videos from systems online to best portray co-consciousness and switching, but please let me know if there's anything that feels wrong in my writing. i want to be as respectful about this as possible, but know that if i did something inaccurately it was not my intention. i am open to constructive criticism and i hope you enjoyed the fic :]
