Chapter Text
sluggish, rainy days like this always leave dennis in a daze. on a lucky week, he gets one precious day off. one day to catch up on his rest, to stretch out his aching limbs and alleviate the exhaustion that sits heavy in his bones. so when his body naturally, cruelly, woke him up at 5am sharp this morning, he was devastated. nothing could put him back to sleep, not with the fatigue that festered into frustration and left him so horribly weak he could bury his face into his pillows and cry.
but he was given one last resort, a final measure of desperation allowed to him by his angel, his savior. a key to robby’s home. a stunning house that always settled into a comfortable temperature that seeped into his perpetually touch-starved skin. the space’s distinct scent was so warm he couldn’t begin to imagine how robby ever forced himself out of the door for work every day. the fact that he pulled himself from the king sized bed each morning was unfathomable in and of itself. it was a safe haven dennis covertly dreamt of every night and robby had so selflessly given him the key.
he was welcome over whenever, always. robby made that clear. but dennis’s response was stubborn, insistent that he’d never come by without invitation. he wouldn’t dare intrude like that. maybe it was the rain that clouded his head, or the build up of enervation over the course of weeks that made him betray all instinct.
the plan was to message robby as soon as he stepped through his front door, waiting till he was certain he wouldn’t back out as soon as the pipedream was becoming a reality. dennis was sure he’d leave before robby was off shift, make the bed to his standards, and even cook him something nice if he had the time. he had every intention of paying him back for the gracious favor of unknowingly letting him crash in his bed.
and his room, god, his room. it smelled overwhelmingly of robby, seeping into the pillowcases and the sheets with a thread count so high dennis would have to bleed himself dry to afford them. the muted tiffany lamp on his nightstand glowed warmly in the otherwise perfectly dark room, blackout curtains keeping the day away even when the sun was shining high, that left him so good and sleepy that he really couldn’t help it. as soon as his rain-soaked t-shirt and sweatpants were discarded to the floor, and the comforter was pressing his perfectly dozy body into the mattress, he passed out into a sleep so deep not even the shock of thunder could wake him.
-
if long shifts at the pitt are harsh, long shifts without the reprieve of dennis’s company are agonizing. there’s something so uniquely comforting in the ability to feel the warmth of dennis’s shoulders through his scrubs when robby desperately needed something to ground him.
his rainy ride home is spent envisioning what it’d be like to go home to him, to have something to fall into after such a draining day, while droplets wash over the motorcycle helmet dennis insists he wears regularly.
and by some miracle, he’s there. in the flesh, in his bed. robby only intended on laying down for a few minutes, maybe half an hour at most. he’s still got to make himself dinner and shower the day off. but nothing can keep the man from caving when he sees the figure beneath his perfectly kept dark comforter and the peek of dirty blond hair snuggled into his pillow.
his intentions are only pure for a split second. it twists into something blatantly sinful when he pulls the covers back to reveal den’s horribly vulnerable state. he’s left in nothing but black briefs that hug his build perfectly, while sprawled out on his stomach with one leg extended towards the end of the bed and the other bent at the knee, hitched up higher.
robby is practically drooling at the sight - the elegant slope of his back, the supple skin on the back of his thighs, the way the elastic fabric of his boxers clings to his heat. he couldn’t possibly resist. but he doesn’t have it in him to do all the disgusting acts flooding his mind, his legs are far too sore and his back aches the way it tends to after a shift that goes on as long as it did. he can dream and fantasize over tugging him to the end of the bed, bending him into impossible positions and drilling into him till he’s a mess all he wants; but all sense tells him it’s not in the cards right now. he’ll have to make due.
“sweetheart?”, he whispers lowly as his tough hands find dennis’s body.
it’s intoxicating, the way his hands look holding his waist, eager thumbs pressing into the small of his back. he wants - needs him to wake up. no amount of patience could keep him from getting what he’s pining for.
“den”, robby hikes one of his knees onto the bed, just between dennis’s legs, “wake up, baby”.
but it’s no use. not even when his lips find the nape of his neck, trailing hot kisses down his spine till he reaches the waistband of his boxers. the boy’s fast asleep, face pressed firmly into his pillow with just slightly parted lips while he inhales his scent with each deep breath. the poor thing needed this, and robby doesn’t have it in him to shake him awake.
so he doesn’t. his hands trail down, groping his ass without shame. he’s testing the waters, working him up to elicit a reaction that doesn’t come. not when his hand slips between the searing heat of his thighs and not when he applies a firm pressure to the clothing just barely concealing his cunt. and it doesn’t take long for dennis’s body to start responding without realization, robby’s greedy fingers ghosting over him till there’s a subtle damp spot forming in the fabric. it’s all the permission he needs.
the bed dips when robby pushes the blankets back and crawls over the student, spreading his thighs further to give himself plenty of access to what he so desperately craves. the groping goes on till he’s satisfied with how flustered he’s getting, finally starting to emit little, sleepy noises that tell him the pleasure is working its way into his dreams. perfect.
he’s good and pliant when he’s this knocked out, allowing robby to pull down his boxers with an agonizingly slow rhythm without shying away the way he tends to. and the slick accumulating sticks to the fabric as it’s tugged down his thighs, a sticky mess aching to be cared for. once one of his legs is free, leaving the boxers loose around the other ankle, he’s perfectly vulnerable for him.
dennis is sheepish, usually spending so much time wrapped up in his own head that he presses his legs together when robby tries to admire him like this. but now, he’s on display, at robby’s mercy. both hands grab at his ass, reveling in the sight when he spreads and shows off both of his holes. if robby wasn’t fucked before, he’s far gone now.
his thumb swipes over his rim, teasing him, while the other hand resolutely presses the pads of his ring and middle finger to his t-dick. the poor baby’s already throbbing. it’s all intentional, firm presses into the puckered flesh and raw skin, toying with the bundle of nerves till he’s leaking filthily. he doesn’t even think when he pulls back and tugs his cellphone from his pocket, using one hand to keep his holes spread when he snaps a picture. he’s beautiful, divine.
finally, he’s ready to give himself the rest he’s been longing for. he mirrors dennis and lays on his stomach, settled directly between his legs and carefully lowering his head till his breath is fanning over his ass. they’re both melting into the mattress, floating in relief they could only find in each other and this miracle of a bed. once his full weight is pressed into the sheets, already feeling the stress of the day ease off his back, he pulls the blankets up to his shoulders to keep them both safe and warm.
a hungry groan slips from robby and vibrates to dennis’s core when he finally licks a slow stripe through his folds. he can feel his brain settling into something amicable while he mouths at his boy, switching between heavy laps that gather his wetness on his tongue and rushed licks that just brush over dennis’s needy dick. he’s stirring now, just barely. his hips circle gently each time the warmth of robby’s mouth smothers his cunt, and his face presses further into the pillow as small sighs leave his pretty lips.
robby’s hands shift from his thighs to between, using his thumbs to spread his cunt open and admire the obscene sight. it gives him perfect access to swirl the tip of his tongue around his erection, flicking back and forth a few times before allowing himself to dive back in and bury his face in the mess. his heavy eyelids finally flutter shut as his lips wrap around his dick, mouthing and sucking for his own pleasure. it’s calming, the taste and the sweetly repetitive actions. he neglects all other needs while he goes down on him, nose buried into his heat and ignoring his own breathing till it’s absolutely necessary.
each time he pulls back for air, he pushes himself forward even more aggressively just after. like he aches for the feeling, needs it to shut his brain off. the only thing louder than the wet squelches are his own moaning, open-mouthed and raspy. nothing brings him more pleasure than when he finally lets himself delve his tongue into his hot cunt, the noises only growing more needy and disgusting while he explores his fluttering walls. it’s slow, almost tender while he circles the pulsing flesh and laps up whatever juices dennis so graciously gives him.
dennis’s instinctive movements are growing more aware, but still lazy and languid. he’s carefully rutting against his face while robby pulls him apart meticulously, leaving a wet splotch on the sheets of both his own mess and the man’s saliva while the pillowcase accumulates with dennis’s drool.
by the time robby’s movements become more intentional, fueled by a deep seated starvation for his student, he’s stirring awake. and robby doesn’t mind, doesn’t let it stop him. his lips are wrapped deliberately around his dick, sucking with a hard pressure and flicking his tongue against the pulsing nerves.
dennis is groggy, erupting into confused whimpers while he tries to lift his hips from the bed. his mind hasn’t quite registered the pleasure yet, nor the overwhelming feeling that’s forming in his abdomen. robby’s hands find the small of his back, pressing down firmly and earning a grunt from the student.
“wha- what’s-? shit, ah- ah”, dennis whines.
he lifts his head up, just slightly, and hopelessly blinks the sleep from his eyes. the poor thing couldn’t be more disoriented, and robby isn’t giving him a chance to process or move while he sucks his dick raw. it’s so much, too much.
“mmgh- fuck, wait-”
the smaller’s all too weak to squirm out of his grasp the way he’s trying to before he can feel his climax creeping up on him. his hips lift and press, squirming in his grip, but robby doesn’t relent. by the time he’s had his fill of torturing his dick, he moves his attention up and shoves his tongue into his cunt again, followed by a loud, unrestrained groan. one of his arms continues to press down on his back, giving him no option to shy away from the pleasure, while his other hand snakes beneath the writhing boy to find his heat. as soon as he has his fingers pressed against his dick, unmoving and simply applying pressure firm enough to gain a little jolt of his hips, dennis is breaking.
“holy sh-it, fuck! ah- ah, ah!”, his voice is breaking, unrestrained and whiny.
he doesn’t have the energy to withstand how hard he comes, the orgasm ripping through every muscle in his body and turning him into a trembling wreck. it doesn’t keep robby from fucking his tongue in and out of him as his walls pulse and helplessly try to push the intrusion out, alongside the rush of slick he swallows happily. it’s perfect - he’s perfect.
dennis’s knuckles are white from how hard he’s gripping at the pillowcase by the time robby is slowly, carefully pulling his tongue out of him. they’re both breathless, panting and at a loss for words. the student is far too fucked out to even begin to question what’s happening, how long he’s been working him open like this. he doesn’t even think to ask how much more he’s expected to endure, a poor lapse of judgment on his part.
he’s lapped clean just after, robby even going as far as to lick at the sheets to make sure not a drop of him goes to waste. and he kisses the sore area over and over, ensuring he’s dripping in adoration as they both try to come down. but robby’s not done.
only a few measly minutes have gone by when robby’s deciding he needs more. dennis is still floating somewhere far from earth, and a comfortable silence hasn’t been allowed to settle properly by the time robby’s strong arms are flipping him onto his back decisively.
“oh-”, dennis gasps, eyes still half lidded despite the sudden shock and licking his lips as he speaks, “you’re home”.
robby laughs breathlessly as he lowers his head again, this time kissing the inside of his thighs. when dennis starts to let his legs shy together, the doctor’s teeth nip at the delicate skin. it’s a warning, however gentle.
the mere feeling of his breath fanning over this now sore cunt makes him stir, and the way he gasps and jerks his hips when robby licks another full stripe up his heat is pathetic.
“robby-! already- i already-”
“i know, i know”, robby’s attention shifts back to his thighs, gracing more sloppy kisses over the area between words. “you already came so hard”, he cooes.
dennis can barely lift his head from the bed to take in the sight with his sleep-heavy eyes. it’s filthy, the way robby has his thighs pried open while he presses his face between them for his own satisfaction. robby’s beard is soaked, and the way he keeps darting his tongue over his still-slick lips tells him he wants more.
“i missed you. so fucking much”.
the sweet, twisted vulnerability in robby’s voice sends a shiver up his spine. he missed him- dennis would be wrong to deprive him of this. so he lets his head fall back into the pillow with a defeated whimper while his still shaky hands find robby’s hair. putting aside how overwhelmed he already is - dennis knows how much this means to robby. he’s never seen his brain shut off the way it has now, broken down and drowning in the taste of his student that he’s finally found peace in.
there’s a steady pressure behind dennis’s hands as he guides robby’s messy face back down, allowing him the reprieve of burying his tongue into his cunt again. and the desperate man’s trying to mumble out what dennis can only assume to be a flurry of “thank you”s while the flat of his tongue runs up in methodic laps.
and fuck, it’s too much. dennis can’t help but mewl and buck his hips off the bed when robby’s lips wrap around his dick again, sucking with a brutal pressure he swears is intended to break him. but the look in his eyes tells him that robby is dumbed down too, pupils blown while he takes lazy glances up through his lashes.
each time he lifts his head to take in the scene, robby’s so lost in it he can’t even take the time to admire how pretty the boy looks from this angle. sprawled out so vulnerably, his own arms wrapped around dennis’s thighs and hands planted firmly on the inside to keep them spread open wide. but he can feel the way his chest heaves each time robby pulls back for air and forces himself down again, nose prodding dennis’s swollen dick as his tongue works him open.
even when robby’s tongue starts to ache blissfully, and his jaw tires into a dull pain, he can’t will himself to give the writhing student a break. both of dennis’s hands paw at his hair and scalp, trying to tug him away and push him further down interchangeably. the pressure builds till it’s too much, leaving him a shaking mess while he uses the little strength he has to keep himself from squirming away from robby instinctively.
robby’s tongue moves with more and more persistence, resolving himself to a mess of his own whimpers buzzing against the student’s sensitive cunt. it’s enough to make dennis shove his head back further, gasping,
“oh my- oh my god. ah- jesus!”
his thighs desperately try to wriggle together, and finally robby allows him some reprieve. his hands slip back, instead both settling on his tummy as his abdomen spasms. dennis cries out when his thighs finally press around robby’s head, only drawing him closer in. tears blink from his lashes and drip down his flushed face, slowly finding their way to the mess of a pillowcase.
robby couldn’t be more gone. his groans only grow more ravenous, the gravelly noises rumbling deep in his chest and only enmeshing with the filthy noises between them and muted, broken “hah”s. his own hips weakly rut into the bedsheets, finding whatever sort of friction he can. dennis can’t even bring himself to admire the shifting beneath the covers he can see each time he throws his head forward, too overpowered by the edge he’s being forced over again.
the world quiets the moment it hits; dennis’s vision fades around the edges and his jaw falls lax in a silent cry. he finishes around nothing this time, robby instead focusing on swirling his tongue around his throbbing dick and only taking little breaks to shift down and lick up the creamy mess forming. his nose does the work for him instead, leaving dennis whimpering each time it presses into his all too sensitive areas.
he has even less time to prepare this time - robby’s cruelly pulling himself away before his high can even settle. dazed eyes follow his figure as the comforter falls back and bunches at the end of the bed, followed by the long-sleeved undershirt robby had kept on before climbing beneath the sheets. he barely finds the energy to remove his pants and underwear after, shuffling around lazily and kicking them off the bed.
robby’s in too deep to focus on anything but his own desire, all sense of mercy and grace dissipates. he’s drunk on his want for the work of art below him, staring up with eyes that aren’t fully present. it’s stunning: dennis’s arms stretched lazily above his head while his legs continue to weakly fall open. the slight irritation forming on the inside of his thighs shows robby just how lost in it he was, is, but the way he still tastes on his lips and beard is enough to strip him of concern.
“i can’t- i can’t”,
dennis chokes out when the tip of robby’s cock presses to the underside of his own. the gentle action sends a jolt up his spine and forces his hips to jerk in reaction. it earns an enamored sigh from the doctor, repeating the action and smearing his own pre over dennis’s poor swollen dick.
“can’t? or won’t?”, robby’s voice is soft, strewn together with a genuine interest.
the student can barely blink back his tears, let alone process the question. but all sense tells him it's can’t - there’s nothing he wouldn’t do for robby.
“i don’t know i- i can’t. i’m sorry, sorry- fuck-!”,
he hisses when robby cruelly slaps the head of his cock against his sopping cunt, shuddering under the sting. but robby doesn’t relent, instead repeating the action until dennis is whimpering instead of turning to his obstinance.
“shhh, that’s okay”, robby whispers with a tone so warm it leaves dennis melting into the mattress, “i’ll just have to fuck all those silly doubts out of your head, yeah?”.
his own hips tremble as he finally pushes forward and lets the tip of his cock press into dennis. it’s impossible to keep himself composed, not when his walls so obediently flutter and allow him to slip in with one torturously slow thrust. he’s all but drooling as he watches dennis’s folds stretch around him till their flushed skin meets, an almost panicked realization to how tight his boy is around him leaving him a mess of little whines and continued twitches of his hips - even when he’s buried balls deep inside him.
but dennis is a wreck compared to robby’s pathetic state. normally he spends more time working him open, prepping him with experienced fingers and waiting till he’s begging for relief. a sob rips from his chest when he opens him up with one thorough push, tensing and clenching around the intrusion till he’s derived to a mess of squirming and gasping.
“hah- just like that, uh huh. my good, good boy”, robby’s gaze is fixed on dennis’s cunt while he speaks, both of his hands continuing to pry his thighs open to give himself the perfect view.
exhaustion has both of them beat, the burnout in their body’s betraying them. but robby gets plenty from this - from kneeling ahead of his student and reveling in the feeling of his cunt clenching down on him each time he rocks his hips forward, from pulling dennis apart and proving to him that robby knows his body better than he ever will himself.
dennis can barely bring himself to claw at robby’s thighs for support.. he has both arms reaching down, desperate to find something to stabilize him and settling for pressing the curve of his nails into his warm skin. and robby doesn’t mind, he’s far too enthralled with the way dennis jolts beneath him when his thumb brushes against his dick.
the babbles dennis finds himself spewing come out closer to incoherent cries, too overstimulated to communicate through the tears. he’d never felt so good, so fucking overwhelmed by something so slow and careful. his brain melts with each firm circle the pad of robby’s thumb drags over his dick, rubbing the mess of saliva and pre-cum under the hood and into his pulsing nerves. his body responds without permission, each shock of pain and pleasure sends his hole clamping down on robby’s dick, leaving the doctor groaning lowly and instinctively rocking himself deeper into him. it’s a vicious cycle, mind numbing and messy.
“ple-please? mmn, robby- ah!”, the poor thing can barely keep his eyes open, articulating anything in this state is a miracle.
“close?”, robby breathes out.
it’s humiliating. it seems effortless on robby’s end, pulling apart dennis bit by bit. he doesn’t have to resort to all the flood of gross scenes that play out in his head when he sees his student like this - not right now, at least. this is enough. his fingers are unforgiving as they continue to knead into him, the movements so gradual and precise that the build up is punishing. even as he tries to shy away, his hips twist and buck robby’s cock into all the right, horribly sensitive spots deep inside him.
robby’s tone drops, heavy with blurred guilt and crushing desire, “you’re taking it so fucking well, doll”.
his movements slow to a subtle grind of his hips into dennis, both of his hands then shifting to his waist. the admiration is obvious, putting no effort into concealing the way he looks the student up and down, committing every detail to memory. and when dennis foolishly mistakes the pause for mercy, he takes in the sight ahead of him too. his tame, trembling hands reach for robby’s torso in tandem, immodestly dragging his palms up the soft hair on his tummy, up his chest and to his strong shoulders - and suddenly robby’s leaning over him. it’s harsh, giving no warning as his thighs are pushed open with more force and arms are rendered useless and hastily wrapped around robby’s neck. dennis couldn’t even begin to process how much further his cock hits into him from this angle.
“you needed this”, robby groans as his forehead settles against dennis’s, his frame swamping the smaller’s body with fluency, “to shut your pretty brain off and let me do all the thinking. needed me to take good care of you, yeah?”.
every thrust into his sore cunt grows more deliberate once dennis is properly pinned into the mattress by robby’s steady bodyweight. the wet noises alongside the unfiltered, carnal thoughts being spilled into the little space between them keeps him good and sheepish, even when he’s entirely unable to shy away in a position like this.
“dr. robby-!”, dennis’s head falls back with the shout, burying his now disheveled fluff of hair into the pillow.
he tries to stay gentle, he swears he does, but he can’t keep the tips of his fingers from shifting into dragging the sharp of their nails down robby’s shoulderblades. the broken skin that trails beneath his fingers’ wake is enough to leave robby whining again - only cracking further when dennis’s legs wrap more sternly around his waist and the heels of his feet press into the small of his back, forcing him closer.
everything blurs when robby crashes their lips together, both dissolving into a puddle of muffled moans and desperate grinding into one another. dennis is too far gone to kiss him back properly, instead letting his lips part obediently while robby’s tongue shoves into his mouth. he nips as his lips and laps at the drool already forming at the corners of his mouth, all while dennis’s eyes roll back and his body continues to tremble in his arms.
they both shatter as soon as the harrowing sensation overtakes both of them. tears stream freely down dennis’s face as his eyes screw shut, the glistening on his cheeks under the lamp’s light sparks something primal in robby. he’s grunting with every uneven thrust, settling into a harsh rhythm determined on working dennis through another violent orgasm. he screams and gasps for air while his abdomen spasms again, just before he lets go, diverting him into a mewling wreck while he makes a creamy mess all over robby’s cock.
the doctor has to pull away from abusing dennis’s already raw and spit-slick lips, instead burying his face into the crook of his neck while he splinters in his arms. robby’s teeth sink into his neck, just enough to leave a few indents and a delicate bruise, if he’s lucky, at the same time that he shoves his cock to the hilt in one resolute thrust. the drawn out whimper released as he spills ropes of cum inside the student is downright deplorable, music to dennis’s ears. they’re both panting while robby slips in and out of him a few more times, selfishly, and lets his spend leak from his used hole and onto the bedsheets.
neither have the capacity to fill the silence that settles around them. they’re both too twitchy, too disoriented after finishing so hard. for a moment, dennis is almost convinced robby’s falling asleep there atop him. and he doesn’t complain, instead basking in the security he finds beneath his weight and still stretched out around his cock. he’d abandon whatever dreams of heaven he had for a few more minutes of this without hesitation.
“mmgh-”, dennis whines as robby starts shifting.
it’s careful, but no where near cautious enough to keep dennis from complaining. he needs the pressure, the warmth he’s finding so much peace in. he needs robby. but he’s already slowly lifting himself off the boy, groaning over the ache in his biceps and the sting of cold air when his cock reluctantly slips from dennis’s heat.
they’re both weak and huffy, staring at each other with half-lidded eyes once robby is finally sitting up just ahead of the smaller again. he looks groggy, to say the least, gnawing at his lip as his mind continues to race. but dennis wouldn’t be able to place that exhaustion with the way robby abruptly grabs his hips and rolls him on his side.
“what’re you…?”, dennis lifts his head to watch, using the back of his hands to wipe sleep from his eyes.
the deceptively virtuous look robby gives as he starts to dip down again is sadistic - and dennis doesn’t even have the time to catch it before he’s being manhandled again.
his leg is shoved up into the air and settled onto robby’s shoulder as he finds himself between his boy’s thighs again. it’s impatient, mean. and still, dennis has never experienced such thorough care before. all he has the strength for anymore is tugging at the doctor’s hair and helplessly humping his face as he’s cleaned up so diligently, lovingly. robby’s too busy tasting himself in his student’s overworked cunt to worry himself over the tears dennis can’t keep from soaking the sheets.
