------------------------------

It wasn’t often that they were left alone in the house together. It was almost too quiet, too uncomfortable, and Sebastian knew his mother would worry about them both equally. Robin herself being away at a carpenter’s conference for the weekend - something both her children and husband encouraged her to do for herself, not for them, not for the community, but for her own interest. And Maru, well, she told her father she would be spending the night at Penny’s but, really, Sebastian could tell that was a lie a mile off and that she would definitely be sneaking around with a certain doctor - and Sebastian is almost a little proud of his little sister lying so boldly to Demetrius’ face.

Which left Sebastian alone with Demetrius for the evening. It shouldn’t have been a problem really, he could have heated up some leftovers in the fridge and stayed comfortably in his bedroom until midday tomorrow when Demetrius would likely be out working. Still there was that itching urge again for a smoke, so he unceremoniously got up, shrugging on a jumper over his plain t-shirt and shorts and left the comfort of his own bedroom.

The air was cool outside, not enough to give him goosebumps on his exposed legs but enough that he was glad he wore a jacket. The transition into fall was fast approaching and Sebastian was grateful, sick of the sticky sweat and stifling heat. He watched, entranced, as the smoke drifted away with the wind, across the lake, into nothingness. But soon enough the cigarette was gone and he made his way back into the house but into the kitchen instead of heading downstairs.

He shouldn’t have been surprised to see Demetrius sitting at the kitchen table, yet the sight of the older man startled him a little, enough to pause in the doorway and for the man to lift his head up from the newspaper he was reading. He gave Sebastian a tight nod of sorts which he weirdly returned in confusion, they were never ones to acknowledge each other's presence but he supposed with the absence of Robin and Maru there wasn’t really any other choice.

“There’s some stir fry left in the fridge,” Demetrius spoke, voice as steady and neutral as ever, as if bored by his own words, his eyes moving back to the newspaper, avoiding Sebastian’s half-hearted eye roll as he went for the fridge.

There was a leftover container of stir fry sat there inside, Sebastian took it out, closing the fridge door behind him, speaking up, “do you want any-”

“I’ve had some already,” Demetrius cuts him off, passively waving his hand towards the younger man, gaze never leaving the page.

“Fine, fuck you too,” Sebastian mumbles under his breath as he turns to open a drawer for cutlery, deciding to eat it cold rather than spend more time around Demetrius whilst it microwaves.

“What did you just say?” Demetrius asked, no, he demanded, that familiar tone of anger rising in his voice like he usually had around Sebastian, not enough to be shouting but patronising.

“I said,” Sebastian starts, turning back around and leaving the tupperware on the counter top, “‘Fine. Fuck. You. Too.’”

Sebastian stops, staring at his step father, and swallows nervously when the older man stands, leaving his newspaper folded on the kitchen table, even tucking the chair under it. Demetrius stops in front of him, close enough to touch and that Sebastian has to look up slightly at him, it’s a little intimidating but that only serves to make him angrier.

“You need to learn to hold your tongue in my house,” Demetrius says, eyes firm and strict on Sebastian who can feel himself flush under the intensity, “you have no respect for me and you never have, the least you can do is not use profanity against me within my own house which I will remind you that you live in rent free so you could learn with being a little nicer now and again, be grateful for what you have got.”

“Is that it?” Sebastian snaps back, eager to be anywhere but in this conversation, “can I go then?”

Demetrius' face changes to something like anger, frustration, impatient for a moment, a mere flicker of humanity before he steals his expression again, “apologise and you may go.”

Sebastian huffs, crossing his arms, pouting like he is no more than a child, fitting as that is all Demetrius seems to see him as.

“No.”

“Sebastian, I do not wish to fight with you, your behaviour was unacceptable and I am merely acting for an apology,” Demetrius explains, a hint of exhaustion hiding behind the monotone, “you need to start accepting the consequences of your actions.”

“Not from you I’m not,” Sebastian argues, wincing as his voice cracks, betrayed by his own emotions, “I don’t owe you shit.”

Demetrius sighs, finally perhaps accepting this is a futile and lost cause, that he and Sebastian are just as stubborn as one another.

“I wish you would not force my hand.”

It happened quickly. Just like the other time, and the time before that, and- you get the picture. Demetrius’ hands burn against his skin, once upon a time Sebastian might have anticipated a slap, something harsh and painful, but the hands are strong yet gentle on his hips, steadying, focusing. And Sebastian hates the way adrenaline rushes through him at the simple touch.

He could push away, Sebastian knows, he has done before with excuses like ‘not now’ or ‘fuck off’, leaving Demetrius high and dry whilst finding himself later, in the shower or hand down his pants, thinking of those hands. He doesn’t this time, letting himself be guided a little harsher than he normally would be - he supposes Demetrius doesn’t want to ‘reward’ his bad behaviour particularly, but they’re never left long, not like this, not for this long.

The kitchen table is a little on the shorter side and not exactly comfortable but it isn’t the first time his stepfather has bent him over it, and Sebastian bets it won’t be the last. The edge of the table cuts a little into the soft of his stomach so he squirms only to be trapped, Demetrius firmly stood behind him, hands on his hips keeping him between the table and himself.

Arousal thrums through Sebastian at this point, there is no denying that is what it is. He’s hot and wet and so fucking horny for his asshole of a stepdad. He’s so fucked. But Demetrius is hot at the backs of his thighs, hands warm and wandering up his t-shirt, urging Sebastian up off the table just enough to worm his hands up to Sebastian’s chest, past the scars that Demetrius never sees because they don’t undress, they don’t take their time, they never have time.

Except they do now.

Demetrius must notice this suddenly because Sebastian is hauled up, still wedged between the table and his stepfather’s quickly hardening bulge. His jacket comes off first, draped over one of the chairs, then his t-shirt, the room is chilly but not cold yet the way Demetrius’ fingers run over his nipples makes him shiver, breath catching in his throat. Sebastian whines when the warmth of his stepfather’s hands leave his chest only to whine that octave higher when they grasp the elastic of his shorts, pulling them and his boxers down in one swift movement, leaving him to step out of them and kick them aside, no doubt to embarrassingly pick up later.

His chest makes contact with the cool table once again, flushed skin against smooth wood, and his cunt embarrassingly exposed to Demetrius. It isn’t anything he hasn’t seen before but the position is humiliating enough to make Sebastian blush a few shades darker than he already is, hiding his face behind his hair as he feels those hands on his ass, spreading his cheeks apart so obscenely, and he knows Demetrius is victoriously taking in the sight of his pussy leaking with such need and arousal for him.

Sebastian mentally curses the fact he can’t see what Demetrius is doing, he wants to see that thick cock pulled out just for him. It doesn’t matter, he feels it soon enough, the blunt head of Demetrius’ cock pressing up and down his cunt, teasing and gathering the slick there, before unceremoniously but slowly pressing inside. And Sebastian hisses out a breath, unable to breathe again until Demetrius’ hips are almost flush with his ass, cock deep and throbbing inside his criminally underused pussy.

And he knows, partially, why Robin likes this guy so much. Demetrius’ cock is thick, stretching his cunt open wide enough that Sebastian knows he’ll feel the phantom stretch of it later tonight and maybe even in the morning. He cannot help the whisper of a moan that escapes him at the carnal feeling of being filled to the brim. Demetrius is warm behind him, hands gripping his bare hips, bent over himself, engulfing Sebastian with his frame.

Demetrius’ breath is hot on the back of his neck, breathing unevenly and, as always, that sends a thrill of vindication through Sebastian, to ruin a composed man to this.

Then Demetrius speaks, “you reek of smoke.”

It’s a statement but his tone is sour with judgement.

Sebastian grunts under the force of a hard thrust, palms slammed flush against the wooden table top, “comes with the addiction,” he forces out.

“You really should quit that nasty habit,” Demetrius counters, breathy in his response, but the grip on Sebastian’s hips tighten - he would not be surprised if he bruised - and he thrusts again, gaining a rhythm of sorts.

Sebastian laughs though, a choked out sort of thing that cuts off with a moan, “right after you quit this one.”

There is nothing but the sound of skin against skin, the slickness of Demetrius’ cock in and out of his stepson’s wet cunt.

He can’t help but edge Demetrius on that little bit more, “imagine what mom would say if she saw us now.”

He does gain a slap for that. An open palmed spank across his right ass cheek, then a one on the left to mirror the bright red palm print growing. It’s humiliating, truely, but what is more is the shriek of a moan Sebastian lets out, panting breath against the wood, palms slicking with sweat as he scrambles to steady himself.

But the table legs wobble under the forceful thrusts and Sebastian’s own weight - if only Robin knew what her husband and son did every so often on her homemade furniture - and Sebastian stops struggling, urging his legs that little bit further apart, doing his best to collect any strength and fuck himself back onto Demetrius’ cock. His stepdad’s grasp doesn’t falter though, letting him be little more than a sex toy to be used and, embarrassingly, Sebastian loves it.

His little cock is so hard and straining between his legs, slick with his own arousal and undoubtedly Demetrius’ too. And Sebastian already knows he’s fucked, that this whole thing is fucked, but he reaches down, wrist uncomfortably bent and arm squished between his stomach and the table, and finds his cock with familiar fingers. Sure, he could wait, Demetrius doesn’t leave him hanging, but he’s impatient, he needs it now.

Sebastian almost cries with relief, pinching and rubbing at his slick little cock, tips of his fingers messily bumping against Demetrius’ cock where it constantly dips in and out of his wet cunt. It’s almost too much stimulation but he’s so close, the harsh, well placed thrusts, the almost complete immobility of his lower half, the friction on his cock and, well, Demetrius doesn’t warn him in the slightest.

His stepfather comes with a long drawn out groan of satisfaction, hips bucking over and over until they settle into grinds, spurting copious amounts of come deep inside Sebastian’s cunt then leaking out of him with each pull and grind of Demetrius’ cock. Sebastian follows over the edge into climactic bliss in moments, fingers scrambling yet quick over his cock as his cunt clenches and spasms around the thick intrusion, milking his stepdad for all he can.

There is no time for Sebastian’s breathing or heart rate to settle. Demetrius pulls his cock out of him with seemingly no care or attention, letting his come leak out, trickling down Sebastian’s thighs and dripping down onto the tiled flooring. Tucking himself away to maintain modesty as his stepson stays bent in half over the kitchen table, nude and leaking come.

“Clean yourself up.”

Demetrius is gone before Sebastian even considers talking back to him, undoubtedly up to the hallway bathroom to clean himself up. And Sebastian just lays there, breathing hard, forehead resting against the once cool wood, hair matted to his skin with sweat. He’ll get up in a moment, collect his clothes, wipe the come up off the floor, and force himself into a shower, fish his stepfather’s come out of his cunt and undoubtedly make himself come again at the thought of how depraved he is. For now he lets himself breathe.

And we fall into each other - Alex/Sebastian

Minors / Under 18s Do Not Interact

Summary: Alex is on the phone with Haley when he’d really rather not be, Sebastian helps to distract him in the worst (best) kind of ways.

Warnings: use of the terms ‘cunt’ in reference to trans guy’s genitalia, non-consensual voyeurism, teasing, light dom/sub play, riding, slight rough sex, fingering

A/N: obviously this is a work of fiction, I don’t condone actually having sex while on a phone call to someone who hasn’t consented to the situation

Word count: 2.4k

------------------------------

“Yeah, Hales, of course, uh huh, yeah,” Alex mutters into his cell phone, his posture bored and relaxed against the couch, one arm swung over the back of the couch whilst his other holds the phone to his ear. He sighs, heavy in his chest, eyes bored as they survey the muted television in front of him. The house is a little on the warm side, the heating on due to his boyfriend’s seemingly constant low body temperature, so, he sits in nothing but some old gym shorts and a t-shirt, listening to the shrill constant tone of Haley through the phone.

It isn’t that he doesn’t like Haley, she’s his best friend, nor does he mind her talking his ear off about her newest shoot or how she’s redecorating her flat but right now listening and responding the best he can as Haley goes on and on about her most recent fling that has, inevitably, broken her heart. Alex doesn’t even attempt the ‘I told you so’ even if he did, in fact, tell her so. She’s nothing if not a hopeless romantic.

“And she totally blew me off as if, like, we hadn’t been together for months and, like, I’d totally been in love with her, she just ignored me, and I was like ‘what the hell?’ because, you know, what the actual hell?” Comes her voice from the other end of the phone, he can almost hear her pacing back and forth, hands gesturing – he’d seen it enough times.

“Uh huh, that sucks,” he supplies automatically, he should have a script for these events at this point. Sure, it was some pretty girl art student this time and that cool business major last time and the time before was the boy who had all his daddy’s money and next time, who knows? Alex knows to mostly just shut up, listen, and offer sympathetic noises at the right times. She doesn’t want solutions, she wants a shoulder to metaphorically cry on, he’d learnt that the hard way.

Sebastian takes that moment to walk in from their office which, really, is an over glorified storage room where he works after Alex told him one too many times that he couldn’t work from bed.

He raises an eyebrow at Alex, uttering quietly as he edges closer to the couch, “who is it?”

“Haley,” he whispers back, mostly mouthing the word.

And Sebastian rolls his eyes, “boy trouble?”

Alex can’t help laughing a little, turning off the speaker function on his phone, leaving Haley to her own devices mostly, “girl trouble,” he replies.

“Same shit, different day,” his boyfriend quips back at normal volume, stepping forward and leaning down a little to capture Alex’s lips in a soft, chaste kiss, all too brief for Alex’s liking, “enjoy.”

Sebastian goes to step away, but Alex moves his free hand to grasp at his hoodie, drawing him nearer, pleading, “stay please, this is torture.”

His fingers are peeled one by one out of the dark material and Sebastian steps away, ignoring the obvious pout on his boyfriend’s face, uttering, “patience.”

“And so she clearly went and bitched about me to them so the next time I saw them they were all glaring at me and I was confused, like, what was I supposed to think? I didn’t think she’d go so low as do drop me in shit, I never even did half the things she said I did, that bitch, but god she was pretty so I’d forgive her. Anyway, she clearly told them that I…”

Alex doesn’t hear a word from his friend, her words are nothing but background noise to the display occurring right in front of him, in the low light of their living room. The dark hoodie pulled up and over, exposing expanses of pale skin, dropped to the floor carelessly, those hands with painted black nails skimming downwards, catching on barbell piercings, lower until they catch on the waistband of tight jeans, popping the button and dragging down the zipper. He struggles a little, like he always does, pushing the skin-tight material down his thighs until they pool around his ankles, he steps out of them, taking the socks off with them, then the underwear, as skin-tight, if not more so, than the jeans, leaving nothing to the imagination, fall to the floor, kicked aside with the rest of the discarded articles.

His mouth is dry and his palms starting to sweat, Alex has never been particularly patient before, but for a sight like this, well, maybe Sebastian can convince him, even just for a little. He watches, a little stupid and dumbfounded, as Sebastian takes two of his own fingers into his mouth, wetting them with saliva before sliding the same two fingers around his cock, down his lips, inside of his cunt just barely. And Alex’s fingers inch to do just the same.

“That was so rude of her, like, in public and everything, she basically screamed at me, the actual audacity of the bitch, in front of all those people, in front of my friends. Like you just wouldn’t. If you were going to dump someone for being a ‘self-centred pretty bitch’ you’d do it somewhere more private right, Alex? Alex?”

Alex swallows dryly, fumbling to put the speaker back on, “right, yeah.”

Sebastian laughs at him, with two fingers inside of himself and his legs spread slightly he still manages to make Alex feel embarrassed.

“Quiet, baby,” is whispered into his other ear, the one not being talked into by Haley.

His lap is then full, bare thighs spread either side of his own still clothed thighs, cunt wet and warm above his very responsive cock, leaking into his underwear at every other moment.

“Like, I get it, I’m not going to be right for everyone, but I thought she was happy, she seemed it, so what? She lied to me throughout our entire relationship? That hurts more than having my ass dumped in front of everyone, was she never happy with me? Then why drag it out? I don’t understand her,” Haley drones on, obliviously.

His cock aches as its fished out of his shorts with the familiar practiced ease that comes with Sebastian touching him, so used to his body, perhaps more so than himself. Alex cannot help the sharp intake of breath and slight hiss as the fingers encircle and squeeze around him.

“Hush, baby, don’t want to let her hear how needy you are,” Sebastian dares to coo at him, accompanied by soft laughter that is borderline mean, it only makes Alex shiver and his cock twitches in the grasp of lithe, cool fingers, pre-come leaking eagerly out of his slit. Sebastian is almost nonchalant in the way he jerks him off, as if Alex doesn’t have to bite his lip to stop himself groaning or force his hips back against the couch to stop embarrassingly thrusting into that torturous grip.

Then his cock is sliding through the slick wetness of Sebastian’s cunt, once, twice, then alarmingly quickly his lover his baring down on him, thighs either side of his own, straddling him and forcing him still. Alex knows his expression must be just short of hilarious – scrunched up in pleasure whilst forcing a sort of silence over himself, it’s torturous in the most glorious of ways. But Sebastian’s eyes are closed, mouth open in a soft panting, and it feels like a small satisfying victory for the moment.

“Maybe I am just a pretty bitch but, you know, she’s not worth it!” Haley huffs, more irritated and louder than before.

Alex supresses a groan, biting his lower lip a little too hard, as Sebastian moves, barely, up off his cock for a moment before grinding down again. He responds, “you know that’s not true, Hales, you just fall too fast, you’re a hopeless romantic, you’ve got to- to take your time.”

He doesn’t know what he’s saying quite frankly, it could be garbage for all he cares. The sight, sounds, pleasures of a nude, pale porcelain boyfriend atop of him is clouding most of his thoughts.

“That’s easy for you to say, lover boy,” Haley retorts, but there’s a hint of laughter, and he’d rather her laugh at him than sulk in her post-breakup mood, “you’ve got it easy, living the high life with your boy toy, never had your heart broken. I’ve seen your Instagram, makes me sick, if it’s not a gym selfie it’s pictures of him, I can practically feel your sappy love dumb expression through the lens. If I didn’t love you so much, I’d totally kill you for being so in love.”

Alex isn’t exactly happy about the segway into his own relationship, Sebastian sat on his lap, grinning like a maniac, clearly having overheard Haley’s words, the smug bastard, as if he doesn’t tell him how much he adores him every day, several times a day. Bastard. He decides to deliver a rather sharp upward thrust in retaliation, one hand on Sebastian’s hip, and the other rights himself with hands on his shoulders, nails barely digging in through the t-shirt, gasping perhaps a fraction too loud.

“C’mon, Hales, you don’t need to be- ah, mean,” Alex stutters out more than he intended, and perhaps patience definitely isn’t his strong suit because he wants nothing more than to ‘accidentally’ hang up on his best friend and throw his boyfriend down onto the couch and fuck him until he has him begging to come and apologising for teasing.

“I’m just telling it how it is, doll, life’s unfair to me but, hon, you deserve love,” Haley says, there’s the soft sincerity in her voice that hurts a little bit when he thinks about it.

Fuck. She needs to stop being so sincere and genuine when he is literally balls deep in his boyfriend who won’t stop his incessant grinding on his cock like it was all he is made to do. But then Sebastian is leaning over, lips a whisper away from skin as he ghosts breath against his cheek, then jaw, before pressing kisses against his throat, foolishly exposed as Alex relents under his touch, and then Sebastian seems content with the permission and sucks.

“Hales- c’mon you know you deserve love too, you just jump in too quick and- and for the idiots that don’t deserve you too,” he responds, barely, with a cut off groan towards the end, attempting to cover it with a soft cough but it just makes him that little more embarrassed which, humiliatingly, makes his cock twitch and hips jerk under the weight of Sebastian who, unfortunately, will not give up until Alex has maybe finished himself inside of him with Haley still on the other end of the line.

“You’re sweet, Al, real sweet, I can see why he picked you up so quick,” Haley responds, lighter and softer, “go have fun with your boy, you perv. Hi Sebastian!”

Sebastian does take that moment to detach his mouth from Alex’s throat, leaving behind wet, red marks, laughing at the obviously mortified expression on his boyfriend’s face, uttering a louder, “hey Haley.”

This is it. This is how Alex dies. Of mortification with his dick still firmly, and hard, inside of his boyfriend on the phone with his best friend. He decides neither can speak at his funeral then.

“Try not to tire him out too much, I need him for tomorrow, he’s my wingman!” Haley shouts, though she need not as Sebastian is right there, lips daring against Alex’s jawbone – and he better not mark him too much if Haley is going to see him tomorrow. Shit.

“Can’t promise that,” Sebastian responds, thankfully, getting his lips away from Alex’s bare skin. His hips though have slowed barely to a grind, seemingly content with the turn of events.

“Goodbye, Haley!” Alex interrupts, quickly and impatiently, hanging up the phone on a giggling Haley. And he knows he’s going to have to face her tomorrow and answer anything she might have but that’s a tomorrow problem for him.

“You’re fucking insatiable,” he says, phone falling quickly from his grasp to instead have two hands on Sebastian’s waist and, easily and effortlessly, he pushes and lifts. Sebastian ends up wide-eyed with his back to the couch cushions and Alex above him, what of his cock had slipped out he gladly shoves back inside with a firm thrust, in no mood to return the teasing or playfulness.

The somewhat shocked yelp that escapes Sebastian only fades into a groan, body arching upwards in an effort for anything more, and Alex doesn’t hold back, eager and needy. His eyes squeeze shut and like a rubber band snapped he comes, hard and fast, almost embarrassingly so, forehead resting on Sebastian’s heaving chest as his thrusts grown sloppy then weak then stop altogether.

“Fuck,” Alex breathes out, taking his time before looking up at his very flushed lover, open mouthed and still somewhat panting as though he hadn’t expected Alex to flip quite so quickly and go quite as hard, Alex laughs a little, “tease.”

There’s still a hint of a satisfied smirk on Sebastian’s lips which does slip and falter when Alex pulls out, fingers quick enough to push his come back inside of him, curling and beckoning. And it doesn’t take long for Sebastian to come, almost silently as his entire body seems to tighten and then relax, legs still splayed either side of Alex, feet hooking around his thighs barely. Alex gets the hint, drawing forward into a kiss that Sebastian eagerly accepts, fingers slipping out of his boyfriend as they swap kiss after soft kiss.

“She’s going to kill me tomorrow, I hope you’re happy,” Alex mumbles between them, “and these,” he gestures to the hickies travelling up his throat, “won’t help.”

Sebastian snickers, actually snickers, his smirk returning but his eyes are something softer, gentler, lovingly.

“She won’t kill you,” he reassures, running a hand through Alex’s hair, “but if she does you have to promise to haunt me.”

Alex rolls his eyes, granting his boyfriend another single chaste kiss before pushing himself up and off him, “deal. Only if you stop seducing me on the couch because we have to clean it again now.”

Sebastian has the decency to look a little embarrassed at that at least.
