Work Text:
It’s been a week since Robby left for his sabbatical. Seven days of Dennis borrowing Trinity’s car to check on his plants, bring in the mail, and use the space as a safe haven when Garcia was expressing her feelings at their own apartment.
But today is the eighth day, and it’s about to be the weekend. Dennis feels like this shift took 10 years off his lifespan and his mind is still reeling with the events of the day, even as he grabs his backpack from his locker. So, by the time he climbs off the bus, weary body nearly tripping down the steps, he realizes that his mind had helpfully supplied him with the directions to Robby’s house, not his.
Perfect.
The situation’s not all that bad, actually. There’s food there, Robby’s got an actual AC and heating unit instead of a ceiling fan, and his water pressure is so good it makes Dennis moan in delight sometimes.
Dennis can never catch a break that easily, though. Because he helped deliver his first baby right at the end of his shift, and his scrubs are caked with blood, placenta, and whatever else had come out during the process. He hadn’t bothered to change there, seeing as he’d become overly friendly with the scrub machine his first rotation there the year before.
So that brings him here, standing at the entrance of the master bedroom, towel wrapped around his narrow waist while he decides if he’s going to cross that line. He wonders if he should just sleep naked in the sheets, but the house is cursed with floor-to-ceiling windows, and in Robby’s words - he’s not sure if his elderly neighbors would survive seeing that. Plus it’s not like Robby would know; he’d do the laundry a dozen times over to make sure the clothes were spotless.
Dennis pads softly into the room, taking the details in. There’s a big oak dresser on the wall opposite of the bed with a single bottle of cologne and a few miscellaneous items strewn about on it. The bed looks like a California king, probably because Robby’s so tall, and there’s a reclining chair in the corner.
The closet is connected to the en suite bathroom, and Dennis suddenly feels like a pervert staring at all of Robby’s clothes. That’s because you are one, he thinks.
His fingers skim the shirts, feeling for the softest one. They land on a worn black tee that has some rock band’s name on it, one that Dennis has never heard of. He snags it off the hanger before returning to the main room, staring at the dresser.
Snooping through your boss’ underwear drawer is probably not the best idea, but Robby must trust him, right? He won’t touch anything else he’s not supposed to.
Dennis finds what he’s looking for in the top left drawer, hesitating before reaching in. He scoots some pairs out of the way, knowing that they’ll be entirely too big on him. Robby probably keeps the pairs that don’t fit him at the bottom or back of the drawer; he has a hard time letting go of things that don’t work for him.
Bingo. A plain pair of forest green boxers - still a size too big for Dennis, but it’ll work.
This leads the boy to where he is now, curled up in Robby’s bed, wearing his clothes, and watching his TV like he owns the place. In fact, he’s got the volume on Scandal up so loud that he doesn’t even hear the door click open downstairs, or the footsteps that echo in the living room.
—
Jack Abbot has had enough of Robby’s bullshit over the years. This “sabbatical” was just another one of the man’s antics, but Jack was still pissed that he decided to actually leave. He thought they were in the clear when that ambulance hit Robby’s bike, but of course Duke was there to fix it up right away. Fucking perfect.
He knew that Robby had a thing for the skittish-looking blonde intern; could tell by the way Robby manhandled him like he owned the kid. And to be fair, Jack could see why he liked him. That cute little body, curly hair, and sweet blue eyes with a gaze that was practically begging for someone to take advantage of him.
He had actually put the hypothesis to a test one night over some beers, making a suggestive comment to Robby about him. He happily watched Robby get all flustered and hard, stammering out a bullshit excuse to leave Jack’s place early.
Jack also knew that he and Robby were probably his type; after hearing Santos gossiping to Javadi about Dennis’ late night activities, he figured the boy had a thing for older guys. Plus he'd heard the Grindr notification go off twice in the interactions he’d had with Dennis.
So when he heard down the grapevine that Dennis was housesitting for Robby, well, he couldn’t help but get a little jealous.
It’d currently been a week since Robby left, so Jack decided to pay his house a little visit. It was a Friday night, and he figured Santos probably dragged Dennis out to a bar after their shift.
He shut the door behind him, tossing his own keys in the bowl on the hallway tree. It wasn’t until he was untying his boots that he heard the noises from upstairs, what sounded like the television playing.
Safe to say he was wrong about Whitaker.
He climbs the stairs slowly, adding weight to his steps to alert the boy that he was there. Still no response. Dennis still hasn’t said anything when he reaches the top, so he calls out softly, “Whitaker? You here?”
Jack rounds the corner into Robby’s room, and fuck, he’s screwed. Dennis lets out a yelp, sitting up from the bed, clutching his chest from the jumpscare. “Doctor Abbot! What- What’re you-” The poor thing can’t even form a full sentence, his chest heaving as he stares at Jack, his mouth hanging open.
“You shouldn’t be here.”
“You shouldn’t be wearing your attending’s boxers.”
He doesn’t even think about the situation he’s been caught in. Not until Jack’s eyes land on his chest, reading Robby’s shirt.
“Nice one, kid.” He grins, standing his ground in the doorway. Can’t wait to see how this one plays out. He decides he’ll have a little fun tonight, on Robby’s dime.
“I can explain! I came after work, and I- I had no clean clothes. So I had to-” Jack cuts him off with a tsk tsk, shaking his head like a disappointed father. Dennis’ face is cherry red, and he can’t help but egg him on.
“Ah, right. What were your plans for the night? Have some guy over, let him fuck you in your boss’ bed, hm?” His words are utterly filthy, and Dennis wonders where he’s going with this. The man starts moving towards the bed, stalking like a predator closing in on its prey.
Dennis looks up at him, eyes teary and wide. “No, I swear! Please, sir, don’t tell Doctor Robby.” He practically begs, bottom lip quivering. The bed squeaks underneath him as he tries to scoot away from Jack, but a large hand snakes around his ankle before he gets far.
“We’ll see about that,” Jack chuckles, “You’ve got that old man wrapped around your finger, y’know.” He grips Dennis’ ankle hard, yanking him towards the edge of the bed. Dennis’ arms lay uselessly beside his head, his legs bent at the knee and spread open slightly, revealing his semi-hard-on.
The tension in the room reaches a peak when Jack starts stroking Dennis’ leg, rough fingertips trailing up his calf. “Doctor Abbot? What’re you doing?” He tries to close his thighs, but Jack pries them back open with ease, eyes drifting down to where Dennis is hard and leaking. Jack’s own cock twitches in his army pants, thickening by the minute.
“Don’t play dumb, sweetheart. I’ve seen the way you and Robby look at each other. Doesn’t help that Santos was out there blabbing about your older hook-ups. We’re right up your alley.” He smirks.
Fucking Trinity, he thinks. He’ll get her back for that one.
“Robby and I didn’t do anything, I swear!” Dennis’ eyes look like they’re about to overflow with tears, and Jack’s never been harder than he is at the sight. The hand on his leg trails up to his thigh, a finger slipping under the leg of the boxers.
“But you want to, don’t you? Want him to put you on your knees in the supply closet, let your attending teach you how to be good?” Jack’s voice is dripping with fake sympathy, almost mocking the boy beneath him.
“This is highly inappropriate, Doctor Abbot.”
“Tell me you want it, sweetheart. I know I haven’t been crazy, you’ve been acting like a little tease.”
Jack’s other hand reaches up to Dennis’ mouth, tracing a thumb along his bottom lip before pushing in. “‘M not a tease.” he mumbles around the thumb, sucking it deeper into his mouth. Jack scoffs at his response.
“Sure you aren’t, kid. What do you say we make that old man jealous, hm? Show him what a good boy you are, make him lose his mind over you.” He uses his grip on Dennis’ jaw to nod his head up and down, slotting his body further between the boy’s thighs until his clothed cock was pressing against his ass. He’s big from what Dennis can feel through the boxers, moaning around the thumb when Jack ruts up against him.
“Yes sir,” he says sweetly when Jack pulls his finger out, “Wanted you since the first time I worked the night shift.” He admits. Jack hooks his fingers in the waistband of Robby’s boxers, starting to tug them down Dennis’ lean legs, freeing his cock. It’s a pretty pink, the tip darker red and leaking steadily, making a mess on his tummy.
“What a pretty boy you are. ‘Bout time we give Robby a taste of his own medicine. Always making little displays in the pitt, thinking I don’t notice you two.” He wraps a hand around Dennis’ cock, thumbing over the flushed head to spread the wetness around.
“Oh my god, Doctor Abbot.” Dennis is a whimpering mess, hips bucking up, trying to get Jack to stroke him faster. He reaches down between his thighs, fingertips pawing at the thick green belt, trying to undo it from Jack’s pants.
The room is filled with Dennis’ panting and Jack’s degrading words, the air around them becoming thick. “Hang on honey, gotta open you up first.” He reaches over to the nearest nightstand where he knows Robby keeps the lube, successfully retrieving the mostly-full bottle.
“How- how did you know?” Dennis has a cute confused look on his face, watching as the man generously coats three of his fingers.
“Seriously kid, we’ve known each other since med school. You don’t think we were experimenting back then?” He laughs, tracing his middle finger around Dennis’ pink hole before sliding in slowly. “In fact, we did after this concert,” he nods down to the shirt that Dennis has on, “Probably before you were even born.”
“Oh jesus.” Dennis moans once his thick finger is in to the last knuckle, nudging up towards his prostate. “That’s so hot. That shouldn’t be hot.” He whines.
“You can’t help it, honey. It’s not your fault your perverted attendings are gonna take advantage of you, you poor thing.” He looks down at Dennis, watching the boy’s cock drool more precum at his words. He slides his pointer finger in alongside the other, scissoring them to stretch the tight rim out. He knows he should take some more time with him, really play with his body, but if he’s hooking up with older men like Santos said, then he can take it.
Dennis’ thighs shake while he’s spread open, hands gripping the sheets near his head. Jack’s hard as a rock in his pants, it’s a shock that the zipper hadn’t burst from the pressure yet. “One more finger then I’ll fuck you, m’kay? Say ‘thank you, sir’.”
“Thank you, sir! Please- please fuck me.” Dennis begs, not caring how desperate he comes off anymore. His cards are out on the table now, and he knows there’s no coming back from what he and his boss are about to do.
“Good boy, Denny, so sweet.” Jack groans as he slides the final finger in, really working him open now, battering his swollen prostate. Dennis is moaning like he’s getting paid for it, cock bobbing on his tummy from the force of the fingers inside him. “Knew I had to get to you before that bastard did.”
He cruelly presses his free hand to the boy’s lower tummy, feeling his fingers moving deep inside him. Dennis keens at the feeling, trying to nudge his hips downwards.
After another minute, Jack can’t wait any longer. He pulls the fingers out of Dennis with a pop, his hole winking, begging to be filled again. He hurriedly unbuckles his belt, undoing his pants just enough to pull his cock out. And holy shit, Dennis thinks, there’s no way that’s fitting inside him.
“See something you like, honey?” Jack grins as he notices Dennis’ wide eyes locked on his cock. He’ll be damned if that’s not the most beautiful dick he’s seen in his life; thick around as Dennis’ forearm, flushed dark pink from the previous neglect, and a few thick veins running up it. His mouth waters at the sight and he was suddenly wishing this wasn’t spur-of-the-moment, that he actually had time to worship that man.
Jack wraps a hand around himself stroking a few times before Dennis places a small hand over his, nudging it out of the way. His jaw drops open, watching as his fingertips don’t even touch around the girth. “I- Is it gonna fit?” Jesus, Jack nearly cums on the spot, his boy sounding nervous like a cute little virgin.
“Don’t you worry about that,” Jack hooks his hands under Dennis’ knees, pushing them up to his chest, “Daddy’s gonna make it fit.” If Dennis’ face wasn’t red before, it sure was now. A jolt runs down his spine, shooting up his cock and causing it to smear more precum on his skin. He looks up at Jack with those sweet, sweet eyes, looking like he’s begging for it.
“Be a good boy and hold your legs up for me.” He commands, releasing them to wrap a hand around his cock instead. He grinds the tip against Dennis’ rim, letting it catch a bit before sliding in.
Dennis moans loudly once he’s pushing in, carving out a spot for him in the tight body. Fuck he’s tight, but Jack bullies his way in, he’s waited long enough.
“God you look so fucking cute like this,” Jack grunts, “Robby’s gonna regret leaving this behind.” He slides a thumb through those pink lips and Dennis immediately hollows his cheeks and sucks obediently.
Dennis’ body is sucking him in like a pro, accustoming itself to his length like he was made for it. Jack thinks he looks beautiful like this - blissed out, completely at his whim.
Through his cock-drunk daze, Dennis sees the older man reaching into his back pocket and retrieving his phone. He’s sliding open the camera app and saying “Smile honey!” before Dennis can even complain or move himself out of the compromising position.
He looks absolutely ruined and Jack loves it. His knees hiked up high by his pink ears, hair ruffled, teary wide eyes, and eyebrows furrowed while Jack fucks him like a whore. You can clearly see that it’s Robby’s shirt he’s got on, too, and Jack is quite pleased with himself for that one. He sends it to Robby without a second thought, sending a snarky “Housesitting is going quite well” text along with it.
Jack’s torment only knocks Dennis deeper into that fuzzy headspace, letting the attending use his body how he wants. He sees stars when Jack delivers a harsh blow to his prostate, pleasure exploding between his thighs. “Yes sir, right there please, mmph, again!”
Each assault on the bundle of nerves seems to come faster, a sob wrenching from his throat. Jack doesn’t slow down, though, just pulls his thumb out to wrap his hands around Dennis’ neck to get better leverage.
“Such a slut for it, aren’t you sweetheart? Gonna have to fuck this tight little ass every night ‘til Robby comes back.” Dennis writhes when he applies pressure to his throat.
Jack’s hips pump impossibly faster, lewd noises filling the room when they meet the skin between Dennis’ ass and thighs. The rough material of his pants and belt must surely be turning his ass red by now, but Dennis can’t bring himself to care. Not when Jack’s looking down at him like that – like a puppy that needs a scolding for chewing on the furniture.
“Yes Doctor Abbot, anything for you. I-I’ll do anything!” He chokes out, hands slipping beneath his knees from the sweat and his trembling.
“You might regret saying that.” The man chuckles, completely pulling out of Dennis’ body. He lets out a high-pitched whine at that, confused on why exactly he’s stopped. “Hands and knees, kid.”
Dennis feels like a baby doe learning how to walk, weak-limbed and meek as he flips himself over. He mewls at the soreness in his body and he knows he’s in for a fucking that he’ll never forget. Meanwhile, Jack removes his prosthetic and props it up against the bed. Robby has a spare pair of crutches in the coat closet that he’ll make Dennis fetch for him in the morning.
The bed shifts at Jack’s added weight, causing the boy to fall onto his chest with his hips jutting up in the air behind him. Jack watches as the pink hole gapes around nothing, and he’s just as eager to get back inside that tight heat as Dennis is to get fucked.
Jack hastily strokes himself before lining back up, pushing all 8 inches in quickly. He places a bruising grip on the boy’s hips, picking up the same pace he had before. Dennis’ brain short-circuits at the rough handling, bearing down on the cock inside him.
“Get your hand under there and play with your pretty cock, baby. Wanna see you cum all over Robby’s shirt.” Jack says gruffly, voice hoarse from the exertion. He’s not gonna last long at this point, either.
Like the good boy he is, Dennis listens and wraps a trembling hand around himself, a whorish moan ripping out of his throat at the sensation. Drool is leaking out of his lips and onto the sheets and he can’t stop himself from babbling a blur of fuck, sir and oh my god I’m gonna cum!
Jack can feel his hole clenching tightly around his cock, creating a vacuum seal from how snug he is. Heat spills over Dennis’ body, his muscles locking up and hips knocking back to meet Jack’s thighs, when an inconspicuous ping is heard over the wet noises filling the air.
The older man picks up his phone, not even halting his thrusts for a moment, and smirks at what he reads on the bright screen.
You son of a bitch. I’m coming home, keep your hands off him until then.
“Looks like it worked, puppy. Daddy’s all jealous I got to this sweet little hole first.”
Jack’s hips pump once, twice more, and Dennis is cumming, sobs shaking his lithe body. He goes limp, jaw hanging open and eyes rolling to the back of his skull as he lets Jack use his body to get off. His hand drops from his oversensitive cock, content to lay there and take it.
The boy isn’t talking anymore, and Jack knows he’s won, he’s fucked Dennis like no one has before, and he knows they’re in for a good time when Robby gets back in a few days. He’s close now too, thrusts growing sloppy and uncoordinated from the pleasure.
He’s rambling too at this point, voice rasp and deep after the long day. “Gonna fucking cum inside you baby, you want that? Hm?” Dennis’ chin dips down in a poor semblance of a nod, and Jack takes that for what it is.
He pounds into the poor boy underneath him until his hips still against the pink flesh of his ass, finishing deep inside him. Jack lets out a string of curses, holding Dennis’ body still until he’s satisfied that every last drop is out.
Jack gingerly pulls his softening cock out, careful not to startle Dennis with any sudden movements, and pulls him to lay down. He’s still shaking with the aftershocks, hole swollen and tender, body sore from holding the position for so long. “Good boy, Denny. Did so amazing for me. ‘M gonna get something to clean you up then we can sleep, okay?”
Dennis nods softly, curling into himself while Jack climbs off the bed. After pulling his boxers up and removing his pants, he slips his prosthetic on for the moment, limping to the bathroom to grab a washcloth.
While the water’s warming up, he snags the crutches from the spare closet down the hall, propping them up next to the bed before grabbing the warm rag and wringing out the excess water.
“I’m gonna take care of you honey, I know that was rough. But Robby and I really care about you. He’ll tell you himself once he’s here.”
“I can’t believe you did that.” Dennis whines, burying his face in the nearest pillow.
Jack laughs at him, gently maneuvering his legs around to clean up his spend and sweat. He tosses the rag off to the side, removing his remaining clothing and prosthetic before climbing back into the bed, pulling the thin sheet around them.
“I like you guys too,” Dennis admits quietly, “I wasn’t gonna have anyone over tonight.”
“I know you weren’t, sweetheart. Such a good puppy for us already.”
Dennis smacks the muscular arm that circles around his waist and pulls him closer to a hairy, broad chest. He would never admit that the nickname made his spent cock twitch again.
And if Robby sprayed extra cologne on his clothes before he left in the case that Dennis might wander into his room, then that’s his secret to keep.
