The Learning Curve

Summary:

“You know what that spot is, don’t you?” Robby teases.

Yes, he should, because he’s a medical doctor.

Right now, he can’t seem to remember the term. Or the area. Or anything, actually.

“The—uhhhm.”

“It’s your prostate,” Robby reminds.

Sounds familiar, Langdon thinks. Maybe.

Work Text:

Langdon toes off his shoes at the entrance of Robby’s place. There’s enough space to fit a wide shoe rack against the wall. Above, a shelf is attached, and he plops his keys into the bowl on it.

That’s as much he can do before the rest of his energy has been zapped from him.

He loves his emergency medicine fellowship. The supervisors are wise and have passed that knowledge down to him, but they’re thorough and don’t let him prance around as he pleases. At least he could get away with a little tomfoolery at the Pitt.

Langdon drags himself up the stairs. He watches his feet carry him to the bathroom door. His hands set up the shower, wrestling his clothes off. An elbow gets caught in the collar of the shirt. Frustration simmers in his mind like a creeping headaches.

Footsteps echo from behind him, and he sighs when two arms wrap around his waist. 

In the mirror, Robby’s face emerges from behind Langdon. He plops his head onto Langdon’s shoulders, arms curling around him.

Robby’s his own personal battery pack. The closer they are, the quicker Langdon can feel himself returning to normal. His bones melt, molding to the shape of Robby’s body behind him.

Hands smooth their way under Langdon’s shirt. Robby helps him pull off the fabric and bunches it onto the counter. He turns his head into the warmth beside him.

“Missed you,” Langdon whispers into his beard.

Robby huffs. “I missed you too.”

The same hands massage at his chest, his neck, his back. They roam around and dig at all the sore sports cramping his body. Langdon can't help the pleasurable little groan that leaves his lips. Then, fingers dip into both the waistband of his scrubs and boxers.

In the mirror, he watches the obsessive look on Robby’s face. His fascination with Langdon’s body is obvious, which only gets Langdon's blood pumping even faster. Robby's honed into the dip of his hips, fingers brushing past his pelvis as he drops the rest of Langdon’s clothes to the ground.

Getting sucked into Robby’s affection never gets old. Even if this part of their relationship is still relatively new compared to how long they have known each other. He finds his own interest stirring south, and he bites his lips to keep himself calm.

Robby raises an eyebrow at the look in Langdon’s eyes. Langdon wishes he would do something. He wonders if he an extends an invitation to shower together if Robby will put his hands on him in ways that aren't just massaging the knots out of his sore muscles.

“Go shower," Robby orders.

“I’m not really in the mood to shower right now,” Langdon confesses.

His bottom lip rolls between his teeth. Robby’s eyes jut down to watch before he looks back up.

“Come find me when you’re done.”

Robby plants one last kiss on his lips before leaving the room. There’s a rising heat in the room that Langdon realizes is actually steam from the shower and not his vulgar thoughts boiling out of his head.

He lets the water rush over his skin. It flows down his head, cooling him off. The moment he relaxes, he feels his muscles ache. Like they forgot the tension that the ER engraves into them isn’t actually normal.

The wash cloth spreads soap over his body. When he looks down, he’s not surprised to see he’s growing interested. That’s easy when Robby molds him into such a laid-back and warm mood.

He lets a hand curve over his cock. Just to give himself something to do while the soap washes off. His teeth dig into his lip at the thought of Robby a few doors down.

Once he shuts off the water, Langdon knows where to find him. Doesn’t bother with blow-drying his hair or lathering himself in his elaborate routine. Just runs a towel over his hair that tousles the strands and pulls up a new pair of boxers.

There was a wordless invite in the way Robby had palmed his body that makes Langdon a bit reckless and cheeky.

He pushes open their bedroom door. Lo and behold, Robby’s sat straight up on top of the covers, back leaning against the bed’s headboard. Unassuming and relaxed as always in a way that makes Langdon a little crazy.

He’s changed into his pajama pants and a long sleeve t-shirt. Despite running cold, he still leaves the AC at 66. Maybe it's for Langdon’s own comfort and his ever-persistent body heat that feels like flames scorching the top layer of his skin. It’s nice to be accommodated in such a small way.

Robby reads a few more sentences of the book in his hands before placing the bookmark in between the pages and setting it to the side.

When Robby looks at him through the top of his lenses, Langdon’s body receives the message with a shiver.

His knees dig into the bed as he crawls across the mattress. He plants himself beside Robby’s legs. Leans in and plants a slow kiss to his lips. The glasses bump his face as he tilts their heads.

Robby stays a passive figure. Lets Langdon dote on him until his hands start wandering south. There’s a solid, not rough, hand around his wrist before Langdon can get past his belly button.

Langdon pulls back. “Not in the mood?”

“Oh, I never said that.”

“Can I suck your cock, then?”

The hand stays firm around his wrist. Robby pulls his glasses off, clamping them shut. He stretches to place them on the bedside table, and Langdon’s eyes follow the pull of his muscles.

There’s a subtle strength in his arms. And when he pulls Langdon into his lap with one arm, he digs his teeth into his bottom lip. Being manhandled by Robby sends a wave of heat between his legs, where Robby currently is. Warm and heady.

Langdon wonders if he missed a lecture during med school. His heart is hammering away in his chest. Is this a chronic condition?

Robby finally leans back into the middle of the bed. He’s holding something in his hand that Langdon can't see. The tiny smile on Robby’s face keeps Langdon’s eyes forward.

“I was thinking we could try something new.”

“Like what?”

A kiss is placed on his lips. Langdon shuts his eyes, leaning in, hoping really, for another kiss. When he opens his eyes, Robby’s looking down between them. Langdon looks down as well.

There’s an obscenity to the way both their half-hard bulges lean against each other. The bottle of lube that Robby is holding doesn’t help either.

Langdon swallows. He’s not a virgin. He’s had enough sex to spread across the rest of his long life. Still, when his eyes land on the lube, he asks,

“What’s that for?”

Robby reads his mind. He knows that Langdon knows what this is for. “I think you know.”

“For me, or for you?”

“For you.” Robby shrugs. “Thought it could be a good time.”

He needs to reiterate his previous thought.

He isn’t a virgin, but he’s never done…this before. As much as he loves a new challenge, there’s a unique obstacle to overcome here. A striking fear sits at the bottom of his stomach.

Except, he looks back up at Robby. He’s smiling, gentle and cautious, because that’s who he is. He’s not someone that would hurt him.

They aren’t cruel to each other. Not anymore.

Even if the trepidation in his stomach tells him this is going to be an uncomfortable, odd experience, he’s bound to enjoy something about it. This is Robby, after all, and he always finds a way to make it work.

“Okay,” Langdon agrees.

“Yeah?”

“Just…be patient with me?”

Robby’s thumb rubs circles up and down his spine, hand resting low on his back.

“Of course, baby. As slow as you need.”

Heat rises to his face. He bites his lip again, but Robby shakes his head and takes its place. Kisses him like he’s sweet and precious. Langdon arches closer as Robby’s hand pats up and down his spine.

Through the slippery slide of their mouths moving against each other, he hears the cap of the bottle snap open. He tries not to think about what’s about to happen. Throws his arms around Robby’s neck instead, pulling himself closer.

Robby certainly takes his sweet time. He mouths at every area of skin he can reach. Peppers kisses along his jaw and neck and shoulders and pecs.

“Does this feel good?” Robby whispers.

It’s just Robby feeling him up really, so Langdon nods.

“Yeah,” he says with a breathy sigh.

It’s hard not to watch Robby’s hand move in the tiny space between them. Even more difficult to hold back the strangeness that is Robby bypassing his cock entirely and slipping the hand further down.

There’s not a lot of room for Robby to move. He’s practically sitting in his lap, legs splayed out wide so that he can rut down on Robby’s bulge occasionally. He could really do that all day. Rub himself against Robby during a lazy makeout session.

Robby’s got other plans though. He makes that much obvious when a slimy finger works between his ass. He can see the determination on his face. Robby wants to make this work. Wants him to feel good and safe.

“God, Robby….”

There’s a heat rising to his face as he lowers a hand around his back to pry his ass open. To help speed up the process, because apparently, this is something he wants too.

Curiosity killed the cat and all that, but he really is intrigued to know what this feels like. If it’ll feel as good as what he’s read and seen.

He has no doubt that Robby will make this as pleasurable as possible for him, because there’s something sinful about how skilled he is with his hands and mouth.

Part of his nerves worry about whether Langdon has the right body for this. If he won’t just be thinking about the crude fact that there’s a finger up his asshole.

Langdon bites at his bottom lip. Not entirely for pleasure, but to give himself a distraction. Robby’s finger is thick, and his body grows stiff with the unfamiliar sensation.

He feels his fingers tighten around Robby’s shoulders. The front-most, primary emotion he’s feeling is discomfort, but he’ll push through if it means having sex with Robby.

Truthfully, this is something Langdon has been obsessing over for months, and he won’t let his own mental blocks stop them.

He likes this position on Robby’s lap. He likes Robby’s fingers, and his hands on his ass, and his mouth sucking kisses into his neck. This should be working.

“How does this feel?” Robby asks again.

“It’s alright.”

Robby gives him a look, and Langdon curses himself. Not exactly the most enthused response from your sex partner.

“It’s good,” Langdon amends with a swallow.

Robby’s hum draws him out of his head. Pulling away, Langdon looks down to see the worried edges of Robby’s face. His eyes are roaming all over him, eyebrows drawn together.

“Let me try something,” Robby says.

“I kinda thought that’s what we were doing.”

Robby ignores the comment as he withdraws his finger from inside Langdon. He clenches around the vacant space he leaves behind. The discomfort is muted now, but Langdon somehow misses the fiery sparks from before.

“You said you wanted to put your mouth on me?” Robby asks.

Langdon nods, head buzzing. It’s endearing how Robby can’t speak a little filthy without a blush rising to his face.

“Actually, I said I wanted to suck your cock, but yeah.”

Robby doesn’t roll his eyes, but the look he gives him is saying he really wants to—again. Maybe he thinks doing so would ruin the mood, but Langdon thinks he likes Robby a little mean.

“Well?” Robby says, gesturing a hand down. Presumptuous in a way that doesn’t come easy for him but, holy fuck, does it do it for Langdon.

His body shudders, senses muddying. Langdon nods again, struck dumb for words. He starts to crawl down Robby’s body, but Robby stops him with a hand to his lower back.

“Uh-uh,” he chastises. “You’ll do it the way I want.”

And, yeah, of course. Of course they will. Langdon nods, but he can’t help the confusion bubbling underneath. He lets Robby reposition him, hands molding his body around.

Langdon ends up with his knees once again beside Robby’s legs. Except this time, his back faces Robby. It’s more like his side is facing Robby, and they form an almost ninety degree angle. His core twists as he lowers himself parallel to the bed, holding himself up with an arm to the mattress.

Robby’s boxers are still on, but Langdon can see just how turned on he’s getting. The front is a damp mess, darkening fabric that’s wet to the touch. Langdon mouths over the fabric. A hint of Robby’s salty taste bleeds through, and Robby hisses.

After lavishing his boxers and tasting more of his own saliva than Robby, Langdon hooks his fingers in his boxers and pulls down. Robby helps, lifting his hips to shimmy the cloth off.

Robby’s cock is eye level with him now as it springs free. The flush to Robby’s face is equally exhilarating as it is endearing. Despite his years of experience, Robby is still shy about a little oral sex with Langdon.

Electrified, Langdon licks a stripe up just to get a first taste. He does it again, and again, and again just to get one more taste. Robby pulls a shaky hand to his mouth, covering his little breathy sighs that are driving Langdon crazy.

It’s not the most gratifying move, licking Robby like a lollipop, but Robby doesn’t seem to mind. His other hand on his lower back keeps rubbing in circles as Langdon uses his cock as a popsicle.

“Enjoying yourself?” Robby asks.

Langdon nods, and his mouth, glistening, drags spit along his length. Runs his tongue underneath the head of his cock just to get a fluttery breath out of him.

The hand on his back grows more assured. He palms at Langdon’s ass, moving from one cheek to the next. He massages the tissue there before splaying his fingers wide. Langdon feels how Robby’s thick fingers frame his hole.

At some point, the lube must have come back out, because the finger circling him is warm with a slippery wetness. Robby doesn't go in. Just…feels the edges of him like he’s memorizing the ridges there.

Langdon can’t focus too much on what kind of shapes he’s drawing. His mouth is too occupied, too full of Robby’s precome dribbling around the corners of his mouth.

Everything about Robby is amplified right now. Langdon’s so low to Robby’s body that he might as well be dipping inside of him. He can’t see Robby’s expression, not turned away like this. Especially not with Robby’s hard cock obscuring the view.

He doesn’t bother craning his neck up to watch Robby. He’s got Robby right in front of him, after all. Hollowing his cheeks, he rubs the head against the inside of his cheek. The slippery slide of skin is magnetic.

It’s purely for Langdon’s own pleasure that he toys with Robby’s dick like this. Using and experimenting with different lavishes and techniques. Robby’s little hums are encouraging to his ears.

As he’s about to take Robby deep, his ass clenches around a finger. It’s an instinct to arch his back, away from the discomfort. 

Another hand finds its way into his hair. Langdon peels open his eyes to blink up at Robby, still propped up against the headboard and poised as ever.

“Relax,” Robby advises in a hushed voice.

“Trying, boss,” Langdon hears himself say.

Langdon feels Robby twitch against his face. He’s large enough, girthy too, to cover part of his face. He must look starstruck like this. Eyes hazy and dragged open with a line of drool connecting his lips to his cock.

“Like when I call you that?” Langdon huffs. 

His breath ghosts against his length, and Robby’s grumble comes out breathy and husky.

“I like when you do as you're told.”

He can take a hint, especially when his cock twitches on his cheek. Parting his lips, he sinks his mouth around Robby once more.

Langdon feels that finger prodding around again. It’s difficult to ignore, but Robby’s scent, strong and heady, keeps him too busy from analyzing his own self-conscious doubts. Doesn’t let himself over analyze rocking his hips back on the single digit.

“That’s right,” Robby coos. “Keep doing that, baby.”

Pleasing Robby will never not hit his brain like the rush of adrenaline. Like a rocket breaking past the final layer of earth and shooting into outer space.

Langdon mouths at the side of his length. He tries to ease the muscles inside him. Taking Robby further as he pokes around.

After a few seconds, Robby’s finger moves. Touches something in him that floods his body with a quick spike of unbelievable pleasure.

Aggh—”

Langdon’s body twitches so loud, his legs scramble from under him. He’s flat on the bed, ass sticking up in the air.

“What the fuck,” he gasps.

Looking up, Robby’s eyes can’t seem to pick between watching the slow slide of his finger or the blush rising to Langdon’s face. He ends up looking Langdon in the eyes with a smirk.

“You know what that spot is, don’t you?” Robby teases.

Yes, he should, because he’s a medical doctor.

Right now, he can’t seem to remember the term. Or the area. Or anything, actually. His mind is a meddled mess with only the words more, more, more shouting through the fog.

“The—uhhhm.”

Robby’s finger curls, and again, like lightning striking the ground, the following thunder rolls through his body as a spike of pleasure. The intensity is so strong, he has to look down to make sure he hasn’t come yet.

“It’s your prostate,” Robby reminds.

Sounds familiar, he thinks. Maybe.

“I knew that,” Langdon mumbles, voice hollow and raspy.

Robby’s a bastard. He feels around the edges of him. Feels the stretch of his hole and avoids that bundle of nerves throbbing to be touched.

As Langdon rocks back, his own cock drags along the mattress. There’s a dampness to the spot beneath him that tells him he’s achingly hard right now.

“C’mon,” Langdon hisses through a full-body shutter. “Do that again.”

“Think you could handle two?”

Langdon stares up at Robby, but the new angle means his hard cock covers half of his face.

He hopes that Robby can see him. Hopes and pleads that he’s doing good for Robby, and that he’ll be rewarded with that mind-boggling feeling once again.

“Yeah.”

“You sure?”

“Robby, I need you to keep fucking me right now.”

Maybe Robby had only asked just to hear him beg. Apparently, under the right conditions, that’s not something that’s beneath him.

His hole tenses when Robby prods a second finger in, but Langdon is much quicker to relax himself. Robby has stretched him out enough to help the muscles expand as well. He can take more of him now.

“Robby,” Langdon pleads, voice high and drawn out. “Again—please.”

“Well,” Robby says. There’s a crinkle of a smile to his eyes. “Since you ask so nicely.”

His fingers move up, then curl in on that same spot. Langdon’s legs twitch all over the place. His mind clouds with an increasingly strong desire for more. More of Robby and his fingers and his cock and this feeling inside him that wants to boil over.

Nghnn—yes—”

Langdon rocks himself on the bed as he scoots back up on his knees. He realigns his face with Robby’s cock. Gives a long lick from base to tip before sinking back down.

It’s almost too much, bordering on overstimulating. When Robby curls his fingers over that funny spot, Langdon’s body spasms forward into the sheets.

Ahh—fucking, Robby!”

His cock ruts against the blanket as he mouths down Robby’s length. As he sucks back up, he drags his cock across the mattress just to fuck back on Robby’s fingers.

“Fuck,” Robby mumbles. “You look so fucking good. You don’t even know.”

Langdon forces his eyes open past the haze of pleasure wrecking him. His pathetic humping means his vision’s shaky. Robby comes to in the brief pauses, but when Langdon does get a clear view of him, he’s no longer smirking.

Robby’s mouth hangs open, tiny, breathy gasps falling out. His eyes are narrowed too, eyebrows drawn together like it’s a surprise to find Langdon so taken over with lust.

The two fingers in him start working faster. Robby’s whole hand moves with the motion, curling over and over again at that spot relentlessly.

“My good boy,” Robby coos. “Just like that. Keep taking me in—hah. Just like that.”

Langdon moans around Robby’s cock, hands grasping uselessly at the sheets. He needs something to hold onto. Something to keep him attached to this planet.

His first hand grasps at the shin in front of him. His other hand aims higher, holding the base of Robby’s cock.

Langdon drags his hips across the mattress in quick ruts. There’s a distinct pleasure building between his legs that tell him holy fuck, he’s about to come from this.

He only lasts a few seconds, and it’s almost a surprise that he’s coming now. It feels like he’s been hanging over that edge for the last fifteen minutes.

The surprise also comes from the fact he’s never felt such an intensity of pleasure wash over him. He’s boneless. Lacking any support that keeps him standing upright.

Robby doesn’t last long in his mouth either. Langdon wonders briefly if his last straw was watching him twitch through his orgasm. Always the giver.

Come dribbles onto his lip and down his chin. He holds a hand to the base of Robby’s cock. Robby’s hips stutter up, and the fingers that are still very much inside him twitch as well. He grazes that goddamn spot inside of him again.

Langdon feels scraped and scrubbed raw. He can’t possibly be roaring for another round so fucking quickly, but the heat thudding low in the pit of his stomach says otherwise.

He flops down onto the bed with a heavy huff. He doesn't care that he’s laying all his body weight on Robby’s leg. He couldn’t move even if the house fell into a sinkhole.

His hole clenches around nothing when Robby finally pulls out. There’s an embarrassing mewl that leaves his lips. The sound echoes in his head, and a fire red blush raises to his cheeks.

It’s too late for them to undo the damage. Langdon apparently is really, truly into this.

Robby’s hand works up his spine and cups his neck. His thumb works over a damp line of his face that Langdon hadn’t even noticed was there. Had he been crying?

Fuck, he is so screwed.

Robby caresses his cheek a few more times, truly ensuring his tears have dried out. His hands wrap around his forearms as he drags Langdon’s body up the bed. Robby meets him halfway, scooting down the mattress to finally lay down.

They lay side-by-side, wordless and thoughtless for a while. Langdon’s still catching his breath, more out of shock than any energy exertion. His eyes can’t leave the pink dustings across Robby’s cheeks.

“Did you have fun?” Robby asks. He phrases his question as a joke, but there’s a cautionary tone hiding.

Langdon gulps. ”I can’t feel my body.”

Robby huffs a laugh. He slides away from him, and for one horrifying second, it feels as though Robby’s about to leave the bed. Leave Langdon and the wet fucking mess he’s made.

In that same second, Robby leans back in. He nudges Langdon to lay on his back. The damp rag in his hand cleans at the come drying on his stomach.

Langdon feels himself growing teary-eyed again for entirely different reasons when Robby plants a kiss to his forehead.

Enough of that. Langdon sniffles, dragging an arm across his eyes. Like a rocket shooting off, he springs off the bed and hovers above Robby.

His eyes are something he can easily get lost in. Often does, really. Big and round and brown bordering on black. They’re wide as they stare at Langdon.

“We need to do that again.”

Robby raises an eyebrow. “Right now? I don’t think my body works that fast.”

“Whenever. That was….”

“Yeah?”

“Good. Really good.”

Robby smiles, and from so close, he can hear a breathy exhale from his nose. Like a sigh of relief. Was he worried about how Langdon would respond?

“Mind-blowing,” Langdon adds.

“Wow.”

“Life-changing.”

“Now, you’re dragging it.”

“Or I just had really good sex with my hot boyfriend.”

Up close, he can watch the individual patches of skin on Robby’s face flare with a blush. Like a slow-changing light bulb.

“We should do that again,” Langdon suggests.

Robby nods with a soft smile. “I’m not opposed to that.”

“Was that…good for you?”

The blush stays high on Robby’s cheekbones. “You’re something else entirely.”

“In a good way?”

Very good,” Robby quickly emphasizes. “I’m a bit star-strucked by you.”

Robby’s eyes darting around means he must not have meant to say that. Post-coital joy making him fuzzy and soft around the edges.

But, Langdon’s curiosity is never quite fulfilled, even if he does know what Robby’s fingers up his ass finally feel like.

“Star-strucked?”

Robby’s hand curls over his ass. His palm is flat as he tenderly rubs over his body.

“How could I not be when I’ve got an attractive young man in my bed?”

Our bed, you mean.”

Robby smiles. “Exactly.”


Langdon wakes on Robby’s chest. Hears the quiet lull of his body still emerged in sleep. When Robby is knocked out, he’s usually out completely. Could probably sleep through a tornado sweeping up the house.

It's one of those rare mornings that they're both off on the same day. The lack of responsibilities and Robby's warm body makes him a bit self-indulgent. Lets himself stretch out of his sleepy haze and drags his eyes over Robby's body.

So, really, the kisses he presses to Robby’s neck are mostly for himself. Keep him occupied and in the arms of his lover.

He licks at skin just above his collar. Mouths and teases the area enough to give a hickey. His hand roams under his shirt to push the fabric up.

There’s a singular buzzing thought that Robby would look dazzling covered in hickies. So, Langdon sets sail and marks up and down Robby’s chest. Sucks a little on his chest and stomach.

He knows to avoid the neck, but one day when they have a few days off, he’ll get him for sure. Decorate that gorgeous area of skin with proof of his love and devotion.

Langdon slides between Robby’s legs which fall open easily. He mouths at the jut between his shoulder and neck as his hands massage Robby’s pecs.

He feels himself growing hard, but he doesn't want to disturb Robby. It takes all the strength in the world to keep himself from rutting against Robby’s lap like he wants to—like he usually does, because Robby has a weird obsession for watching Langdon get himself off.

A hand curls into his hair. Langdon looks up from where he’s mouthing just above Robby’s waistband and smiles.

“Did I wake you?” Langdon asks.

He wonders if the breath of his voice tickles, because Robby’s stomach clenches. He rubs a palm down his face. Can already hear him saying how it's ‘too early for Langdon’s nonsense.’

But, like always, the hand in hair is encouraging. He pets at Langdon rather gently. Scratches and massages with the tips of fingers in a way that melts his brain and makes everything a little fuzzy.

“You should keep doing what you were doing," Langdon murmurs.

Robby lifts his hips, readjusting his legs around Langdon and pulling him closer. The bedsheets fall off Langdon’s back and pile around their ankles.

“Can you fuck me?” Langdon asks.

Robby raises an eyebrow, face a little amused. “You liked it?”

“Came all over you last night, didn’t I?”

A cute blush rises to Robby’s face. He never thought he’d use a word like ‘adorable’ to describe a fifty-five year old doctor, but if the shoe fits.

Robby settles against the headboard. He pats his lap, and Langdon scrambles to sit on his legs. They’re thick enough to give Langdon a cushy seat that he’s discovered he loves to take over.

He runs his hands up Robby’s chest and cups either side of his neck. He sees Robby’s soft smile as he watches Langdon do as he pleases. Mapping his body with his hands up to his face and rubs his thumb under those tender eyes.

“Insatiable baby,” Robby coos quietly.

Langdon leans close. Hovers his lips in front of Robby’s before pulling back. Robby chases after him with a grunt. He narrows his eyes when he catches Langdon's little trick.

“Let me finger you again.”

Fuck.

Langdon wiggles around in Robby’s lap. With a grin, he moves to peel off his boxers. Robby slaps his hand and mutters a teensy ‘stop that.’ Langdon’s help goes as far lifting his hips and watching Robby push the fabric down.

Robby leans over towards the bedside drawer—Langdon leans too, because Robby’s got an arm wrapped tight around his back—and picks up the lube. They hadn’t even bothered to put it away last night.

Wrapping his arms around Robby’s neck, Langdon lets himself get lost in kissing Robby. Partly because he loves the feel of his lips, but also partly to distract him from Robby rubbing at his ass.

The sensation starts to build a pool of heat in his stomach, but part of his past anticipation is still sitting heavy. But, the anxiety starts to dissipate when Robby runs a finger around his rim.

It doesn't hurt, luckily. Not a bit. He’s still a little loose from last night. So, when Robby dips a slick finger in, feeling around, Langdon’s mouth drops open.

“Robby—”

He hasn’t even hit that fucking spot yet, but he’s already panting. His blood is rushing in his ears. He thinks maybe Robby’s heart is hammering the same way. There’s a slightly deranged look in his eyes as he stares up at Langdon. Intense and adoring all at once.

Then, with a curl, Robby does hit his prostate. Langdon yelps, tightening his arms around Robby. He leans in closer and smushes their cheeks together. Lets Robby rock them side-to-side as he adds a second finger and massages that spot.

Robby must be looking over his shoulder. Staring down his back, surely, and watching his fingers slide in and out of him. Langdon hears him huffing like he’s too absorbed by what he’s seeing to regulate his own breathing.

His hand on the back of Langdon’s neck is tight, keeping Langdon pressed close. Like Robby can't stand to be too far from him either.

Langdon feels drool dribble out his mouth. He wipes his hand across his face, lacking any coordination and precision. His back arches up as something strikingly hot shoots up.

Nghnn, shit—”

With a palm to Robby’s chest, Langdon pushes away. Robby follows the movement with his eyes and a smirk, fingers curling faster and faster on that same spot. He’s hitting a rhythm that’s pushing Langdon towards that cliff’s edge that he doesn't want to fall over just yet.

Aghh—wait, wait. St—”

Robby’s fingers immediately stop in him. He’s still as a statue, but his eyes move up to Langdon’s face. His face drops with a frown that Langdon is terrified to find endearing. Robby looks all over as he licks his lips.

“Are you okay? Does something hurt?”

“Feels too fucking good. I was about to come.”

Robby hesitates, a smirk pushing onto his face. “What’s the problem, then?”

He moves a hand behind him to palm at the erection that’s been poking his underside for the last ten minutes. Robby bites his lip, and Langdon immediately wants to trade places and kiss him deeply.

“I wanted you to fuck me,” Langdon explains.

Robby wiggles his fingers with knitted eyebrows. “Kind of currently doing that.”

“Robby. I want you to fuck me.”

“Oh.”

Robby runs a palm down his beard, mouth gaping a little. Langdon pushes a finger into Robby’s mouth.

“Gonna let the flies in if you keep your mouth wide open like that.”

Something must snap in Robby. His head turns into Langdon’s hand and sucks on the single finger in his mouth. Saliva pools on his tongue and soaks Langdon’s finger. He dips another finger into Robby’s mouth, and he sucks eagerly.

Robby’s fingers grow slack in him. Like he’s forgotten what he was originally doing, and he accidentally brushes against that spot in Langdon.

Fuck. His legs twitch against Robby’s hips, and he falls back on Robby’s lap.

A hand wraps around his wrist and pulls it towards the waistband of Robby’s boxers. Robby peels his eyes open and struggles to know what to look at first. It’s fascinating to watch his eyes jump around Langdon’s face.

“If you want me to fuck you,” Robby says slowly. “You’re gonna have to get me ready.”

“Yeah,” Langdon hears himself say immediately.

There’s an immediate need to follow. His hand pushes down Robby’s boxers only as far as he needs. Langdon wraps the sopping wet hand around Robby’s cock. He’s pleased to feel wet of his precome already slicking him up.

It’s an easy up-and-down glide, and Robby leans back with a sigh.

“You’re very good at this,” Robby sighs.

“I know what you like,” Langdon replies back, beaming with pride.

The look on Robby’s face cracks something in him. He rolls his head to the side, smile pulling from cheek to cheek. His fingers are still inside, and Langdon thinks he does it on purpose when he massages that spot again.

Langdon feels himself melt. His shoulders hike up, hand spasming before he reroutes back to a normal rhythm. His thumb slides over the head, and that hiss which falls from Robby’s mouth is delicious. He keeps rubbing that spot to hear Robby curse again and again.

“Okay, okay,” Robby interrupts. “Fuck. That’s good.”

Langdon grins as he licks the precome from his fingers. Not that it’s a lot, but he enjoys how Robby tastes, and it’s just as satisfying to watch Robby’s eyes drop wide like he’s doing something scandalous.

“You’re a fucking tease. Get on your back.”

Langdon frowns. “Why can’t I ride you?”

The fingers pull out of him, and two hands massage up and down Langdon’s hips. Robby’s little smirk sends heat spiking up his spine. He unintentionally arches his back into the touch.

“Honey, you can ride me all night long, if that’s what you want,” Robby whispers. “But to start, it may be easier on your back. I want you on your back."

He really wants to stay in Robby’s lap. It’s a bit petulant, but he enjoys feeling close to Robby. Chest-to-chest, legs intertwining and knocking into each other.

He supposes that can happen in any other position, so he complies and lets Robby twirl them around. Langdon lands on the bed with a soft ‘umphf’. 

It's nothing new to have Robby hover over him, but the sight never gets old. He's a bit lost in the soft look on Robby's face, that he doesn't notice the condom he pulls out until Robby's teeth tear open the thing, because he's a show off and knows that makes Langdon's stomach do tricks and it's fucking working. But, it does bring an important conversation to mind.

"Wait," Langdon says. "Do we need that."

Robby scrutinizes him with a wild look. "You are a doctor of medicine. Protective sex is important."

"Don't lecture me right now. I'm already hard." Langdon sits up on his elbows, and he pushes past the nice blush on Robby's face to voice his concerns. "I mean, do we need to use them? I'm clean, and if you're clean too...."

The time between the words leaving Langdon's mouth and Robby's response takes longer than Langdon hopes. A bit of anxiety sits in his chest as he sees Robby's face flicker through several different emotions.

"I'm clean," he finally says. "I trust you."

Robby sets the opened condom wrapper to the side. He turns back to Langdon with a heavy sigh. Langdon tries to appease him with a smile.

"If you'd rather use it, we can," he says.

Robby shakes his head. His hands massage up and down Langdon's legs. Like he's working himself up to this. Like it's his first time here too. The shared nerves eases Langdon's own self-conscious anxieties.

"You wanna feel all of me, hmm?" Robby voices.

The statement goes straight to Langdon's head, and then it goes straight to his dick. Langdon nods his head, but its a loose movement. His brain's all mushy, and he's losing control of himself.

"Yeah, I do. Robby, I wanna go all the way."

"Okay," Robby sighs. He shifts, hovering just a bit closer over Langdon. “Are you ready?” 

Langdon curls his arms around Robby’s neck. Bends his arms so Robby has no choice but to lean as close as into Langdon’s space.

He won’t lie. There’s a fearful amount of anticipation sitting in the bottom of his stomach. But, there's also heat and an intense, fiery need to melt into Robby’s hands. To know how it feels to come from Robby’s cock alone.

Langdon nods.

“I need to hear you say it.”

“Do you want me to beg? That’s definitely something I can do, you know.”

“Just—don’t be a brat.”

“I think you like when I’m being a brat.”

“I like when you answer my questions,” Robby deflects.

A hand on his ass cuts his joke short. He licks his lips and nods again before remembering Robby’s words.

“Will you…start slow?”

Robby’s smile is sweet as he says, “as slow as you want, baby.”

“Not that slow. I still want you to fuck me into this mattress, Robby.”

Robby huffs an air of amusement. His eyes are soft as he shakes his head. He leans down to press a kiss to his lips.

“Okay, okay.”

Just when he thinks the show is finally getting on the road, Robby reaches behind them and pushes Langdon’s body up with one hand. There’s a base impulse to comply, so when Langdon keeps himself floating off the bed, Robby slips a pillow beneath his lower back.

“For your back,” Robby explains. “For when I ‘fuck you into the mattress’.

Langdon barks a laugh, but it’s not all that funny when he realizes it's happening to him. His own desperation to come and the screaming desire to finally feel Robby inside him muddle his brain. He’s not responding like a normal person.

Damn Robby and his stupidly attractive face and clever hands.

The fingers running around the rim of his ass make way for Robby’s cock. It’s not an easy slide even with the lube and precome slicking them both. He already knew he was on the tighter side and Robby on the girthier side. They have to both put in genuine effort to fit together.

Langdon hisses, low and pained as Robby pushes in. He can feel Robby’s eyes like a physical weight as he takes his time.

“It’s okay,” Robby appeases. “You’re okay. Shhhh–shhh.”

Something about Robby shushing him sends a flare of heat running to his face. He’s toeing that thin line between affection and patronizing that really does it for him.

He’s never felt so full in his life. His body is struck still, a single minded focus on the way Robby fills him up. He’s not at all surprised at how much he enjoys being surrounded by Robby, but he hadn’t expected to enjoy how completely weak he feels.

His arms and legs fall numb as Robby settles into him. Their hips are touching so closely, and the strong collection of bodily fluids and heat in that one spot sends a shiver up his spine.

“You okay?” Robby questions.

Langdon opens his mouth to respond, but—

Aghh—”

Robby…he must not mean to do it. It probably occurred from readjusting his hips or lifting Langdon into a more comfortable position.

All Langdon knows is that his brain is blank. Like all his trains of thoughts have just collided into one another and caused a fiery explosion of his neural pathways.

He rubs against that fucking spot in him. That area that drives him insane and brings out a rather needy and whiny side of him that somehow they both enjoy seeing.

Langdon grabs at Robby’s hair. It’s a harsh tug. Probably ripped a few short strands out, but Robby grins like a madman. All the fear has fallen away, giving in to an affectionate desparation.

He pushes their heads together, but there’s not much space to close between them. Their noses bump together, so close, but Langdon can still feel Robby’s smile against his face.

“Fuck me, Robby. Please, fuck. You need to fuck me as hard as you can.”

“What happened to slow and gentle?”

“We can do that later. Fuck, do it, Robby.”

Robby nods. He wraps two arms around Langdon, one high around his shoulders and one low on his back. A rush of cool air falls between his legs, and Langdon shivers with a frown before realizing it’s from Robby pulling back, and he’s—

Langdon’s voice cracks. It’s airy and high-pitched in a way that should be embarrassing. But, it’s not, because Robby’s actually pushing into him like he wants to break the bedframe.

Fuck—Robby. Ahhh–”

“Just like that?” Robby asks through heavy breaths.

“Yes, please, Robby, don’t stop, Robby—”

Robby’s pleasured pants are loud in his ear, and when Langdon turns, he sees how heavy-lidded his eyes have become. It’s become an obsession to see just how consumed Robby can become by lust.

Lust, and love, and complete devotion. And it’s aimed at Langdon of all people.

Langdon curls his arms tight around Robby’s neck. Brings them chest-to-chest, and the drag of their chesthair is surely going to leave a drag of red all along their torsos later, but Langdon doesn’t care.

His nipples catch onto the expanse of Robby’s chest, sending just another tiny spark of pleasure to his cock. Feels himself growing tenser like the final push up a mountain hike.

“Robby, I’m close—”

The puff of air in his ear is amused. Demeaning. “Already?”

“Fucking—”

He’s going to end up killing Robby one day. With his bare hands, too, but for now, he settles with gripping the back of his head and tugging his head.

He sets his mouth behind Robby’s ear and sucks. Saliva pools over the skin, and it’s hard to get a grasp, especially through Robby fucking into his body like tomorrow doesn’t exist.

His body’s loose, moving with the push of Robby’s body. He can’t help the embarrassing little mewls leaving his lips. He’s losing all control of his body. Molding, really, to Robby inside him as he fucks him at the pace he needs. Deep, steady, hitting that same spot over and over.

Ah—you like this?” Robby asks, holding his body close. “My cock’s what does it for you, baby?”

His hands are tight around Langdon’s biceps. He’s getting chattier too, tongue loose with his pet names and his questions. Langdon realizes that Robby’s getting close too.

“You’re close too, right?” Langdon teases back. “You—Nghn—”

Robby’s wrapped a hand around his cock. His hand is slick and warm as he pumps him quick and steady. The way that’s meant to get Langdon to become overcome with pleasure. He’s trying to get Langdon to beat him to the punch.

“All night long,” Robby says. “I promised, didn’t I?”

Landon fucking whines. God, he won’t stop replaying that noise in his head, and he knows Robby’s probably doing the same thing.

It doesn't matter, though. His body falls slack into the sheets.

Langdon gets the energy to peel his eyes open. Robby’s staring down at him with glazed eyes and a heavy pant. It’s attractive to see the morning light from the window curl over the curvature of his muscles.

Langdon can’t help but push a hand up his torso. He squeezes Robby’s pec and reels with joy when he hears that quiet whimper. Robby bites his bottom lip and looks Langdon in the eyes with the face of a man about to fall apart.

“Frank,” Robby whispers.

It takes a few seconds for his brain to compute what’s happening. “Yeah?”

“Can I….”

Langdon smirks. “You wanna come in me?”

Robby’s nod endears him. He can’t say no to those watery eyes and pout and, god, that fucking body. He doesn’t want to say no, anyways, but it’s fun to keep Robby on this ledge.

“Please?”

Oh god.

That sweet look in Robby’s eyes and his pleading. Langdon bites his lip as he nods. Yeah, Robby’s definitely adorable.

“You can come in me. Go on.”

Robby sighs. He sits back on his knees and grabs Langdon’s waist with a force that will definitely bruise. Instead of pulling back, he pushes Langdon forward and drags him onto his cock. Like Langdon’s just something to move around for his own pleasure.

“Frank. Fuck. You feel fucking incredible.”

His face heats up as he watches Robby lose himself. Both their faces are fixated on that single spot between them. Robby’s hands are tight as his hips fuck in and out. Langdon flies a hand out into the sheets to keep himself from whimpering.

“Robby—”

Robby’s tongue is loose as he grunts a moan. He’s not high-pitched, not like Langdon. More throaty and husky, much like his voice as he says,

“You’re doing good—so good. Always so good for me, baby. You take me so well.”

It’s bordering on too much, feeling Robby slipping past that same spot that has his body shaking. He doesn’t hit it quite as often, clearly fucking Langdon at a pace meant for Robby’s pleasure.

The thought of that is…fuck. Langdon’s truly fucked in the head. He’s proud to bring that look to Robby’s face. To see him lose control of himself and come inside him with Langdon’s name on his mouth.

"Can I—" Robby asks, grunting in between words.

Langdon doesn't need him to finish his sentence to know what he wants. He nods, before realizing Robby's too dazed to actually see him clearly.

"Yeah—Robby, fuck—do it."

Robby’s head drops onto Langdon’s chest. All he can see is how his back heaves with effort to inhale, exhale, inhale again, but he's overwhelmed with how much fuller he has become, if that was even possible.

Langdon drags a heavy hand over the muscles of his back, eyes locked on the dips and bumps of his body. He takes in the hot sensation between his legs.

It's...not as unpleasant as he was anticipating. To be filled so entirely by Robby actually makes him feel adored. Like he's the only one who can make him feel this way. 

Langdon winces when Robby looks up. His eyes are wide like black holes that suck him in. The straight line of his mouth starts to worry him.

“You okay?” Langdon asks.

“You’re the most incredible person I’ve ever met.” Robby hovers a hand over his mouth. “Oh.”

Langdon feels himself grin. That loose-lip is getting him in trouble again. His stomach tightens again when Robby’s hip moves. He’s a bit too overstimulated for Robby to be moving around so much.

“Robby.”

“Yeah?”

“You’re still inside me.”

Robby’s head finally peels away and looks down. That scandalized look on his face is always a joy.

“Fuck. Right.”

With a palm to his stomach, Robby pulls back. It leaves Langdon with an obvious emptiness that he can’t get off his mind. His legs fall onto the bed, and there’s not enough energy to move from the starfish position he’s found himself in.

Luckily, Robby does, and he stands from the bed. He leans down and runs a loving hand up Langdon’s body before saying, “stay there.”

“Can’t move,” Langdon says. “Wasn’t planning on it, either.”

Robby smirks but doesn’t add anything else as he pulls up his boxers and leaves the room. That feeling of abandonment doesn’t rise to the front of his chest like it had last night. He knows Robby will be right back. Can hear him in the bathroom running something under the water.

Robby circles back into the bedroom. He sits beside him, knee digging into the bed. Thinks he’s going to wipe the come off Langdon’s stomach, but he starts with his forehead. Dabs away the sweat before moving towards his stomach.

“You gave me a hickey.”

Langdon hums. “I think you mean ‘hickies.’ If you look down—”

“Not these,” Robby grumbles.

Langdon traces his fingers over the bruises. He’s always been pretty good at making sizable, prominent hickies. He can’t wait to watch these change colors over the next few days.

Robby pulls Langdon’s wrist up his chest, then his neck, then to behind his jaw. Langdon pushes Robby’s head to the side to see the loud red mark right behind his ear.

Ah. He’s broken the golden rule. No visible hickies.

“Well, at least now no one can say you’re cranky cause you aren’t getting laid.”

“Thank you so much for still contributing to the Pitt’s ever-churning gossip mill months after your residency has ended.”

 “Always happy to help, boss.”

Robby stares him down with a glare, but his mouth stutters into a smile. He plants a hand on the other side of Langdon’s body and hovers over him.

“How are you feeling?” Robby asks.

Langdon stretches his body, lifting off the bed with a long groan. He feels his face ache with a grin. His eyes flutter shut as he stares at Robby. The light looks nice over him.

“Incredible,” he mutters.

Robby’s hand is slow across his body. A gentle drag that nearly tickles. “Did I…hurt you?”

With a spike of energy that takes genuine energy to muster, Langdon curls an arm around Robby’s neck and drags him down. Presses a kiss to his mouth, and they lose themselves in the drag of lips for a few minutes before Robby’s back gives out.

“That was amazing—you felt amazing," Langdon assures.

Robby ducks his head, but Langdon can see his smile still. Langdon presses another kiss to his cheek just because it's in reach, and because he can.

"Good. Good."

The towel suddenly moves between his legs, and Langdon can't help the groan that escapes his lips when Robby begins wiping at his own come leaking out of him. It's hot. Not just temperature-wise, but mentally as well. He can feel the heat in the pit of his stomach roaring for another round.

"I'm sorry—"

"If you apologize for coming in me, I'm going to hit you"

Robby looks up at him with a face that suggests that he wouldn't mind that punishment at all, and that's...definitely something to examine at a different time. When Langdon's brain isn't a melted mess, and Robby isn't staring at him with those lovely eyes.

“We’re doing that again,” Langdon declares. At Robby's raised eyebrow, he adds, "in every position—and all over the house, too. Hey, do you think the motorcycle is sturdy enough to hold the both of us?”

Robby looks up, and for a split second, Langdon thinks he’s about to refuse the idea. But he’s got that mischievous grin, and his hand is still warm on his thigh as he massages the muscle.

“If we’re careful,” Robby promises. “If you keep yourself still.”

Langdon takes a second to pretend to think over the idea. “We’ll work up to it.”

Robby’s laugh isn’t loud. He’s quiet, just like the calm of the morning they’ve woken up into. He fits perfectly under the glow of the new day’s sun.
