Chapter Text
Dennis sat at the small table in the kitchen of Robby's apartment. Outside the window the sun was going down, and Dennis was growing impatient. He knew how crazy things could get in the ER, he know how often Robby has to stay past the end of his shift. That didn't stop him from bouncing his leg anxiously, willing himself to not look at the clock. The heat in his stomach was making him dizzy and short of breath.
He got up, moving to the living room and flopping on the couch. He stared at the ceiling while his mind drifted to Robby. All of Dennis' favorite parts of Robby flashed in his head. His strong arms, his big hands, his stern jaw. God, he could climb him right now. Palming his needy cock, Dennis sighed, his eyes fluttering closed so he could focus on conjuring a detailed mental image of Robby's hip bones, the dark brush of hair leading right down to the base of his--
Metal rattled in the door. Dennis' eyes shot open and he froze. Robby pushed the door open, smiling at the sight of the younger man. Dennis jumped off the couch, eager to greet him with a kiss.
"So good to see you. Need a shower." Robby mumbled into Dennis' neck, his arms wrapped around Dennis' waist.
Dennis laid on the bed, trying to be as patient as possible. No doubt Robby had a chaotic day. And being that much older than Dennis surely didn't make things easier. Let him take a breath. Dennis rolled on to his stomach, eyes closed, trying to breathe deep and slow.
In through the nose.
The steam from the bathroom was making the bedroom humid. He could feel sweat on his lip.
Hold it.
Dennis slipped a hand under him, just something to grind against.
Out through the mouth.
He rocked his hips slightly.
In through the nose.
Dennis could feel himself growing harder, stifling a whimper into the comforter.
Hold it.
His other hand gently gripped the sheets. He arched his back, pushing harder against his palm.
Out through the mouth.
The pipes squeaked and the water stopped running. After a moment, Robby emerged from the bathroom, a cloud of steam accompanying him. He froze when he saw Dennis. For a moment he just stood watching the younger man, the way his body moved so fluidly, the pretty little whines he made barely audible with his face turned down towards the bed. Robby's cock twitched. The kid knew how to rile him up.
"And just what am I going to do with you?" Robby said slowly, drawing out the words. Dennis whined, swaying his hips.
"Whatever you want, just -- Please. I need you."
Robby climbed on top of him, straddling the younger man's hips, his cock resting perfectly against Dennis' ass. The weight of it made Dennis keen beneath him.
"I can see that," Robby said, stroking his blond curls. "So needy. Couldn't even wait for me to get home."
He dragged his hands down Dennis' back, bringing them to rest on his hips with a squeeze. Dennis arched his back, pushing his ass harder against Robby's cock. Robby tsked at him, lightly slapping his ass.
"Such a naughty puppy, hm?" Robby leaned forward gently to pull each of Dennis' arms behind his back, securing both wrists in one large hand.
"Yes, sir," Dennis whined, squirming beneath the weight of the older man. "I'm sorry, sir."
"It's a little late for that," Robby sighed, using his free hand to slap Dennis' ass again, harder. "Now I have to punish my poor little puppy."
He reached forward, taking a handful of hair in his fist to lift his head. With his other hand, he gripped Dennis' wrists, keeping him in place while he started to grind against his ass. Dennis moaned, the light contortion of his body pushing his cock against the mattress even harder.
"Please, please, I'm sorry," Dennis cried. He could feel his cock dripping, no doubt making a mess of his boxers.
Robby released his wrists and pulled him up, his chest to Dennis' back. The hand in his hair reached around to the front of his throat. He kissed his shoulders and the sides of his neck slowly.
"Please what, baby?" Robby growled into his ear. Dennis gasped, his hard cock trapped in his boxers. He squeezed his eyes shut while he tried to catch his breath.
"Hm? Please what?" Robby asked again, grinding against the boy, reaching around to palm his cock. "Oh, you really got yourself worked up, didn't you?"
He let out a light laugh, the heat on Dennis' neck making him shiver and whine pathetically.
"Come on, puppy. Use your words." His voice dripped with condescension that made Dennis' limbs weak.
Dennis took a deep breath desperately trying to ground himself, to regain his ability to speak.
In through the nose.
Robby's thumb brushed his adam's apple.
Hold it.
Robby hummed a kiss against the side of Dennis' neck.
Out through the mouth.
"Please fuck me, sir. Please." His voice gave out on the last word, more of a whimper than a plea.
Dennis could feel Robby smile against his shoulder and his cock twitch against his ass. He melted under the weight of the older man. Restrictive, without a doubt. But there was no doubt Dennis was right where he wanted to be-- under Robby's control, physically and emotionally.
"You sound so pretty when you beg for it," he said, leaving kisses on Dennis' shoulder. "You haven't been a very good boy though, have you? I can't reward you for bad behavior, puppy."
He bit down on Dennis' shoulder. The boy yelped and Robby squeezed his cock in reply.
"I'm sorry, sir," Dennis groaned. "Please, I promise I'll be so good. I'll be such a good boy for you."
"Oh, I don't doubt that. Especially after I'm done with you."
Dennis might as well have lost consciousness. Robby pushed him forward, Dennis landing on all fours. He didn't even have Robby's cock in him yet, and he was scared he'd cum any second.
Robby pulled off his boxers, spit into his hand, and reached around to stroke Dennis' cock mercilessly, making him gasp and twitch immediately.
"I'm gonna-- Sir, please. I'm gonna cum," Dennis panted.
"I don't think so, puppy," Robby cooed in his ear, his fist on Dennis' cock keeping its speed. "You're going to behave for me."
Dennis squeezed his eyes shut, willing himself to obey.
"Please, sir. Stop, I'll cum. Please," he begged, desperate
"You better not," Robby said sternly. The wet sounds of Robby's hand on Dennis' slick cock took over the room. The noises were obscene, pornographic. Dennis moaned like Robby was fucking him hard and deep.
"Wanna be good, sir, please," Dennis managed. Robby's pace on his cock didn't falter.
"Such a needy boy, you couldn't even wait for daddy to fuck you," Robby sneered. Dennis' cock throbbed in his hand and he squeezed it. Unintelligible whines poured out of Dennis' mouth. He was getting close, God, so close.
"I'm sorry, daddy, I-- I needed you so bad."
Robby wet him thumb in his mouth and brushed it against Dennis' hole. Dennis flinched then tensed, eyes screwed shut. His whines turned to moans, uncontrollable and animalistic. He was done for.
"It's pathetic. Such a bad puppy."
With a harsh jerk, Dennis came, Robby's hand unrelenting on his cock while he shook and cried out. Robby pressed his cock hard against the boy's ass. With a groan and a whine, Dennis exhaled and collapsed, flat on his stomach, just where Robby wanted him.
Robby rolled him onto his back and took Dennis' twitching cock in his hand.
As if regaining consciousness, Dennis opened his eyes, desperate to catch his breath, the sensation becoming too much for him.
"Please, please," Dennis whined, grabbing at Robby's hand, stroking his sensitive cock.
Again, Robby tsked and shook his head at the wide-eyed gasping boy.
"Sweet puppy, I'm not done with you yet."
