Work Text:
What struck Dennis the most about housesitting for Dr. Robby was how quiet it was.
For Dennis’ entire childhood he’d lived on a farm with three older brothers and dozens of animals, so there was always some sort of noise and commotion at all hours of the day.
Then, during college, he briefly lived with three roommates who enjoyed making elaborate meals in the middle of the night and Dennis would regularly be kept up with the sound of pots and pans, at least before the rent got too high and he got evicted.
The hospital was open 24/7, so even if there wasn’t anybody else on the upper floors, where Dennis was sleeping, there was always a constant stream of people and movement happening below. After a while, the noises just faded away into the background and it was sleeping in stark silence that actually made Dennis uneasy.
And then, he lived with Santos, who was a fairly relaxed roommate, for the most part, but it was still comforting to know that there was somebody else in the building with him.
Compared to his past living experiences, Robby’s house was surprisingly solitary and silent. It took Dennis a while to get used to it.
On the first day of Robby’s sabbatical, and subsequently, Dennis’ first time inside of his house, he felt like a strange intruder.
Dennis had fumbled with the keys in his hand before finding the right one and unlocked the front door, slowly, as if cops would suddenly materialize and arrest him for breaking and entering. It was a silly fear, Robby was the one who gave him the keys in the first place, but it still felt wrong to just go into somebody else’s home alone, especially if that somebody else is your senior attending.
Dennis wasn’t sure what he was expecting, but when he opened the door he was faced with… a pretty normal looking house. The kitchen was modern, with marbled counter tops, a black stove, and dark wood cabinets. The living room had a soft brown carpet covering the floor and a large leather couch sitting in front of a tv that looked twice the size of the one he and Santos shared. Down the hall there was a bathroom, Robby’s master bedroom, and a guest room.
He checked the slip of paper in his pocket Robby had given him and entered the security code into a small alarm box on the wall next to the door.
Dennis took off his shoes and scanned the house, trying to memorize how Robby liked to keep everything so, if he moved anything, he knew how to put it back.
He went inside the guest room and put his bag down. This was where he’d be staying for the next three months.
There wasn’t much in the actual room except for a queen sized bed and a single nightstand. There was a bookshelf, but it was completely bare except for a small stack of medical journals.
Do they even print this stuff anymore?
Dust had collected on almost every surface in the guest room, but Dennis wasn’t going to complain. He could handle a little staleness in exchange for no rent.
The first two days were mostly spent cleaning and figuring out where to place his belongings without messing with anything of Robby’s. Robby had told him to help himself to anything in the fridge, which at first Dennis was too self conscious to do, but then he remembered that if he wasn’t going to eat those apples in the bottom fridge drawer, they’d rot and then nobody would eat them. That was a good enough argument. So, for the sake of reducing food waste, he let himself break his own rules and eat out of Robby’s fridge.
Mid-bite of his apple, Dennis’ phone lit up with a reminder that said, “DON’T FORGET ABOUT GUINEVERE”.
Dennis quickly grabbed a mug that had a photo of a very grumpy cat wearing glasses on it, filled it up with water from the sink, and went into Robby’s bedroom.
He was extra careful not to mess with anything in there; he couldn’t deal with the embarrassment of Robby accusing him of rummaging through his belongings.
He searched around the room before, there, sitting by the bedroom window in a brown flower pot was ‘Guinevere’. Robby had given Dennis specific instructions for how to care for the aloe vera plant, specifically not to over-water it.
Robby’s voice echoed in his head, “You’re gonna think ‘oh she seems thirsty, a little extra water won’t hurt, right?’ Wrong. She’s a finicky thing. You douse her no more than once every two weeks, when her soil is completely dry.”
Dennis pressed down on the soil around the plant to check it was dry, and then he dumped the water into it.
Dennis took this job seriously- it was a real responsibility that Robby had given him, outside of the hospital. Dennis couldn’t help but think that Robby asking him to housesit was an olive branch that would blossom into them spending more time outside of work, that would lead to them being more than just coworkers.
When Santos found out about Robby’s offer, she teased him relentlessly. She knew very well about his less-than-workplace-appropriate feelings towards him.
Dennis wasn’t naive enough to think anything would actually happen between them- Robby was twice his age and treated him more like a lost puppy than a romantic option.
Still, his crush was harmless and it was his. If Dennis wanted to reminisce about Robby’s graying beard, and his sly smile, and his large arms, and intelligent brown eyes, and-
Well that was his business.
It wasn’t that ridiculous of a fantasy, though, you’d have to be blind not to see how attractive he was. Dennis had spent many nights over the past year of working at the Pitt replaying every time Robby touched him. A pat on the shoulder, a fist bump, hand on the small of his back (it happened once, and Dennis almost evaporated into the air), all innocent enough but still they fueled the fire.
And now this: the housesitting. He wouldn’t have asked Dennis for this favor if he didn’t trust him and respect him, at least a little.
Regardless of Dennis’ futile mission of searching for hidden meaning in what Robby did, he liked living in his house.
After the first week or so, he started becoming more and more comfortable in it. He was less obsessive of where he left his belongings and he started actually cooking without being paranoid about accidentally burning the place down.
By the time that Dennis had been staying there for over two months, it had become a proper home to him.
Dennis was enjoying one of his few days off, relaxing on the guest bed, and he considered texting Santos to see if she wanted to go out and do something together. The quietness was peaceful, but, occasionally, boring.
Although he'd never admit it out loud, he sort of missed having Santos around. He didn’t miss listening to her and Garcia going at it at one in the morning, though.
He texted her, but she responded with: “sorry fuckleberry, i’m working all day but maybe 2morrow????”
Dennis smiled and rolled his eyes at the nickname.
Before he could respond, his phone screen suddenly went black. He tried to turn it back on, but- nothing. Damn. He must have forgotten to charge it.
He reached on top of the bedside table, but couldn’t feel anything. He checked under the bed, in the drawers, and inside his own bag and he still couldn’t find his phone charger.
Did he leave it at work yesterday? In all the chaos of the Pitt, he couldn’t remember.
Maybe Robby has an extra one somewhere?
At the beginning, he would have been too nervous to mess with Robby’s stuff, but by that point he had long grown relaxed about it. Dennis snooped through the living room and the kitchen, pulling open random cabinets and checking every outlet, but couldn’t find anything.
He considered peeking into Robby’s bedroom.
Even though he’d gone inside a handful of times to water Guinevere, it still felt separate and more private than the rest of the house.
It’ll just be for a second.
He opened the door and dipped his head under the bed to check if there was a charger on the outlet and- still nothing.
Without thinking much of it, Dennis pulled open the drawer on Robby’s bedside table.
Dennis choked on his own breath. Sitting inside the drawer was a bottle of lube and a small box of tissues.
Ah.
His gaze landed back onto Robby’s bed. His face warmed. How many times had the older man sat there, jerking himself off? How many times had he come into his hand in this exact spot?
Something stirred in Dennis’ stomach and he couldn’t stop imagining Robby using that lube. What would his cock look like? What noises would he make?
He pressed his thighs together and felt the wetness growing between them.
He looked at Robby’s bed.
His want quickly began to snowball, bigger and bigger.
He shouldn’t. He knew it was wrong, but that only added to the thrill of it.
He considered putting everything away and leaving, pretending he didn’t see anything.
But…
Screw it.
It’s not like Robby would know.
He laid down on Robby’s bed and sprawled out. This is so stupid. Am I actually going to do this? It turned out that horniness was quite good at drowning out common sense.
He wriggled out of his plaid pajama pants until he was just in his oversized shirt and boxers.
He trailed his right hand under his boxers and spread himself open. He worked himself up until his middle finger was soaked and started rubbing small circles on his clit.
Dennis was actually jerking off in his attending's bed. Every second he ruminated on that thought, another shock of arousal went through him. He rocked his hips forward and moaned into the empty room.
He slipped two fingers inside of himself and imagined they were Robby’s. He clenched down, but he still ached for something more.
He turned his head to the side and sighed against Robby’s pillow. Although it had been over two months now, Robby’s scent still hadn’t faded and he breathed in a mix of woodsy aftershave, soap, and cigarette smoke.
Dennis had a brilliant idea.
Robby’s pillows were stiff and kept their form well, unlike the soft floppy pillows Dennis had gotten used to sleeping on during his time living inside the hospital.
He grabbed one of the pillows and put it in between his thighs, so it pressed directly against his crotch. He started slowly, dragging the pillow back and forth against his cunt. The pressure and drag of it was delicious and soon all Dennis could think about were the sparks buzzing in his head.
He started speeding up until he was fully humping the pillow, unashamedly chasing his orgasm.
The bed springs squeaked quietly. Dennis bit his lip and whined when he wrapped his legs around the pillow and shoved his hips against it.
He'd have to wash the sheets and the pillow later. He imagined Robby coming back in a few weeks and sleeping soundly right there.
He still had his boxers on, but they were soaking wet. The texture of the wet fabric rubbing against his clit was intoxicating. He liked when it wasn’t completely smooth- the slight roughness just made him more desperate.
He ground down on the pillow, imagining Robby’s leg or his hand or- fuck- his face.
He started breathing heavier and letting out small moans as he sped up. He closed his eyes and focused solely on the slow, hot pleasure building up in his spine.
“Uh.”
Another voice spoke.
Dennis’ eyes flew open and he was faced with what was possibly the most horrifying moment he’d ever experienced in his twenty-six years of life.
Robby.
Dr. Robby stood in the doorway to the bedroom, with one hand holding his motorcycle helmet, and the other still on the doorknob. He was back from his sabbatical, a whole three and a half weeks early.
Dennis shot up straight and the pillow slid out from between his thighs. He flinched at the sudden loss. “Dr. Robby. I-”
What the hell could he say?
There was no way to hide what he was doing. He couldn’t see himself, but he knew his face was probably red and his pants were halfway on the floor. For fucks sake- he even left Robby’s lube out.
A pit opened up in his stomach. That was it. It was over. Robby was going to fire him on the spot and he’d be kicked out and he’d never be able to show his face anywhere in Pittsburgh again. Dennis stammered out, “I’m so sorry, I didn’t- I thought you wouldn’t be back for another month?”
As if that would somehow justify masturbating in his bed.
God, and he was making noises. Outloud. How long was Robby standing there? Did he hear him when he came in?
Maybe, maybe this is all just a bad dream?
Dennis blinked, and silently prayed that when he opened his eyes again, Robby would magically be gone and this was just a horrible dream.
His heart dropped when he saw Robby was still there, staring at him. His expression was unreadable. Finally, Robby said, slowly, “I had to come back early- I texted you.”
Shit. Dennis’ phone was still laying in the guestroom, dead.
Robby let his helmet drop to the ground, cocked his head to the side, and said “Is this what you’ve been doing while I’ve been gone?” His voice was low and cautious.
Dennis shook his head frantically. “No- No! Not at all. I just- I’m so fucking sorry. I’ll leave.”
Maybe if I beg, he’ll take pity on me.
“I didn’t say I wanted you to leave.”
Dennis’ brain was overheating; any more of this conversation and he was worried smoke would start pouring out of his ears.
He replied, “Wh-what?”
Dennis expected to see embarrassment, anger, confusion, or even disgust written on Robby’s face, but instead he looked hungry.
Robby stalked closer and Dennis was frozen, still sitting on his bed, like a deer in headlights just waiting for the crash he knew was inevitable.
Dennis looked up at Robby, who loomed over him. Robby picked up the pillow that was pressed up against Dennis just a few seconds ago.
This can’t be happening.
There was a clear wet spot on it from where it was rubbing against the sticky fabric of Dennis’ boxers.
Red-hot shame expanded inside of Dennis’ chest.
I'm dead. I'm dead and this is Hell.
Dennis abruptly grabbed his pants and stood up. “I’ll go, I’m sorry.”
Robby dropped the pillow and put his hand on Dennis’ chest to stop him from bolting out the door. He said, “You’re not listening to me, Whitaker. Let me be more clear: I don’t want you to leave.”
Dennis didn’t get it. “But, but…”
Robby lightly pushed Dennis backwards, until he fell back onto the bed.
Ohhhh.
Dennis got it.
Robby added, “Unless you want to leave?”
Dennis couldn't think straight. Was it some kind of insane trick? A prank?
Still, he wanted nothing more than to stay exactly where he was, laying on Robby’s bed, looking up at him.
He shook his head.
“Good. That’s what I thought.” Robby leaned down until his face was hovering right over Dennis’.
Dennis couldn’t tell you which one of them made the first move; it happened so fast it didn’t really matter.
Dennis wrapped his hands around the back of Robby’s neck and pulled him down at the same time that Robby cupped his face and pulled him up into a scorching kiss.
There was no preamble. One moment they were coworkers in a potentially humiliating situation, the next Robby was kissing Dennis like a man starved.
It was wet, and heavy, and not at all graceful.
And, fuck, did it make Dennis feel desired.
If Dennis thought the scent of Robby’s pillows were overwhelming, it was completely different having him so close. Everything about him was warm and irresistible and Dennis didn’t think he had ever wanted something so badly in his life.
Even just a kiss was enough to make him dizzy.
Robby’s hand rubbed Dennis’ cunt through the outside of his boxers, making him gasp and grab his arms. He smirked and said, “Naughty thing.”
Robby repositioned Dennis towards the middle of the bed and peeled off his boxers, so he was left naked from the waist down.
He didn’t have a moment to feel self-conscious, though, as a second later Robby kissed Dennis again and rubbed two fingers around his cunt. When they were properly wet, he slid them inside and- “Oh. Shit. Robby.” Dennis moaned.
It was far better than when he had used his own fingers earlier. He stretched him open and rubbed deep inside until he pressed against a spot that made Dennis' legs shake.
Robby pushed the palm of his hand against Dennis’ clit and Dennis feverishly started grinding down on it. The same hands that he’d watched perform a thousand procedures and save hundreds of lives were now fucking him easily.
He was already so close to coming beforehand, so it didn’t take long at all for Dennis’ whines to pitch higher and for him to shove down against Robby’s hand desperately over and over again, until his back arched suddenly off the bed and he shivered through a mind-numbing orgasm.
Robby kissed him through it, muffling his moans against his lips.
Robby slowly pulled his fingers out and Dennis took several, shaky breaths. He mumbled, "Oh fuck. I can't believe that just happened."
Dennis still wasn’t totally sure that he hadn’t gone completely delirious. That would be more logically than if Robby really was in front of him, putting the hand that had just been inside Dennis up to his mouth and licking it clean.
He blinked trying to refocus his eyes on Robby, who started stripping naked. Dennis openly stared at every new bit of skin exposed. He eyed Robby’s dark chest hair and god, those arms- he needed to get his hands back on them as soon as possible.
“What? You wanna take a picture?” Robby teased, while he unbuckled his pants.
Dennis mumbled, “Kinda. Yeah.” Robby’s dick was sitting in front of him, hard and perfect and it was better than any fantasy he’d had. It was big, which wasn't surprising considering how much larger Robby was compared to Dennis, and Dennis needed it inside of him now.
“You with me, kid?”
Dennis nodded. The parts of his brain required to produce speech were still booting back up.
Robby sat back down and kissed him again. The softness of his lips contrasted with the intensity of, well, everything else. Dennis wrapped his hand around Robby’s cock and stroked it leisurely. Robby gasped softly and said, “Shit, I have been wanting to do this since the first day we met.”
That was a piece of information Dennis was going to hoard forever.
He tried to catalogue everything he saw, from the curve of Robby's cock, to the vein running up the side, to the way his pupils dilated when Dennis jerked him off faster. In case this was his one and only shot, he wanted to remember as much as possible.
Dennis said, “I um, I’m on birth control.”
Robby kissed down his chin and neck. Dennis relished in the feeling of his beard rubbing against his skin. Robby teased, “You are so eager, aren’t you?”
Finally, he pulled back and said, “Lay on your stomach.”
Dennis turned around so he was laying face down on the bed and he wriggled his hips up, towards Robby.
Robby’s hand dug into Dennis’ hips as he dragged his cock against the outside of his cunt, making it slick and wet.
He was still a bit sensitive from his first orgasm, but he didn't pull away.
Dennis moaned when he felt Robby’s blunt head push in, stretching him out.
Dennis wasn’t even fully naked, he was still wearing his shirt, but it didn’t matter. Nothing mattered except for the satisfying weight of Robby’s cock inside of him.
Robby kept pushing until he bottomed out, with his hips pressed against Dennis’ ass. Every nerve in his body felt alive and hot.
“Ah, fuck. Robby. Please. Good. S’good.” Dennis paid no attention to how whiny and pathetic he probably seemed.
Dennis clenched down and nearly came right then at the sensation of being so full.
“Jerking off in my bed. In my house. I bet you were just dreaming about this, huh?” Robby started thrusting into him at a pace that was near fatal for Dennis. He dug his fingers into the bed covers as his whole body shook with the force of it.
Dennis nodded against the bed. “Y-yeah. Mph. Oh my god. Yes, I wanted-mm.”
Robby’s voice was deep and breathless. “Ah- fuck. I wish you could see yourself right now, you look perfect.” Dennis liked hearing how much of an effect he was having on Robby.
The angle let him thrust deep, deeper than Dennis’ last (far more brief) sexual trists had been.
Dennis lifted his hips and groaned as he got lost in the constant pressure.
Robby leaned down so he could whisper in his ear, "What a lovely thing to come home to, and making such pretty noises-" Dennis hid his face in the covers, embarassed at being exposed so completely.
Robby’s thrust became more erratic, he dropped one of his hands down to rub against Dennis’ clit and the mounting pleasure peaked far faster than Dennis expected. He gasped, half in surprise, as his whole body tensed and he clenched around Robby’s cock.
Barely a second later, Robby slammed back inside of him as his dick twitched and came deep, leaving Dennis’ legs shaking.
He shivered and whimpered at the warmth filling him. Robby's come is inside of me.
Robby pulled out slowly and Dennis flinched from the over sensitivity. The two of them collapsed, boneless and tired onto the bed.
Robby dragged his hand across his face and said, “Fuck. That was…”
“Mhm.” Dennis felt the satisfying blanket of afterglow settle over him.
The two of them just laid there for a few seconds, catching their breath.
Robby turned to look at him and said, "You okay? I wasn’t too rough, was I?”
“No, I’m great. Fantastic.”
Robby chuckled. “I can’t fucking believe you were getting off on my pillow. I didn’t peg you for that kinda guy, Whitaker.”
Dennis laughed at the absurdity of it all. “In my defense, the front door was locked and I thought I had a lot more time.”
“Next time just text me, I’d be happy to help.”
Next time?
Dennis bit back a smile.
Next time.
He let himself sink further into the mattress.
Santos is never going to believe this.
