Sam’s breathless and panting as he rides Dean, leaned against the headboard, while he praises Sam, litters his throat with pet names that end with a bite at the base of his neck. Sweat rolls down his tensing body, rolls down like Dean’s voice over his skin full of admiration for how Sam feels around him, how good he is, how pretty, beautiful all those long limbs aching with stress to make himself last a little longer.
“C'mon baby, lose it for me-”
“Dean-” Sam gasps in warning, eyes shut, jaw dropping as he seats himself fully. He’s shivering, hair falling in his face as he huffs out a breath before picking up speed again.
“It’s all right, baby boy, I got you-”
The taller man bows his head on a grunt. His hips falter and Dean smirks into those lips that he pulls toward him by cupping the back of Sam’s head; his fingers tangle in his hair possessively. Sam’s makes a noise somewhere between pained and hissing and it makes Dean pull a little harder.
“Fuck- Dean-”
“What’s wrong, sweetheart?” Dean croons lovingly, voice slightly shaken up because fuck- fuck, man- Sam’s falling apart on his dick and he’s looking to Dean like wants him to stop and keep going until everything is too much, until his sight whites out. “Look so pretty, babe, fucking perfect-” he kisses him gentle but Sam overpowers him, breath harsh, hands gripping either side of Dean’s head. Sam’s begging with his eyes, pleading silently with his thrusts snapping and stinging Dean’s skin; Sam’s hips roll slow with Dean’s hands on them and then-
“C'mon, come for me, baby boy-“
Sam seems to suck his words in because he’s shuddering and burying his head into Dean’s shoulder while the other folds his arms across Sam’s lower back and follows suit because Sam is fucking gorgeous and Dean can’t help but fall over the edge with him, silencing his groans into Sam’s neck and then kissing along it, whimpering slightly as those hips drag up his length while clenching to make all his muscles tighten and lock up.
”Jesus, Sammy,“ he lets his head fall back, chest heaving as Sam rocks into him. “Good- good- perfect, Sammy, baby boy-” Dean hums at the feel of lips on his neck. Even though they’re spent, he can feel Sam smile into the skin there, his teeth sinking in slightly. “Did so good, babe- ah!” and then they sink hard into the spot where neck meets shoulder and all Dean can do is groan and let Sam mouth at every inch of Dean’s glistening, sated body.
