Mark slammed the door shut behind them, his breath already ragged. "Get on the bed, ass up," he growled, yanking his shirt off. Jake didn't hesitate. He stripped fast, climbed onto the mattress on all fours, and spread his knees wide. His hole twitched in the cool air, already slick from the lube he'd worked in earlier.
Mark's cock was a monster, thick and veined, nine solid inches of heavy meat swinging between his legs. He stroked it once, twice, spitting on the head for good measure. "Look at that fucking ass. Begging for it." He stepped up behind Jake, rubbed the fat crown up and down the crack, then pressed hard against the tight ring.

Jake pushed back. "Shove it in. I want every inch."
Mark didn't tease. He gripped Jake's hips and drove forward, forcing the massive head past the muscle in one steady thrust. Jake's hole stretched wide, burning and clenching around the girth. Inch after inch sank deep until Mark's balls slapped against Jake's taint and his pelvis pressed flush to those spread cheeks.
"Fuck, yes," Jake hissed. "Deeper. Split me open."
Mark pulled back halfway and slammed home again, setting a hard, pounding rhythm. Each thrust buried the full length, the thick shaft dragging along Jake's inner walls, hitting that spot that made his own cock leak onto the sheets. The sound was filthywet slaps, skin on skin, Jake's broken moans every time Mark bottomed out.
Mark leaned over him, one hand fisting Jake's hair, the other reaching under to grab his leaking dick. "Take that huge cock, you greedy fuck. All the way in your ass." He hammered faster, balls swinging, sweat dripping onto Jake's back. Jake's hole fluttered and sucked around the invading meat, gripping every ridge and vein.
They stayed locked like that, doggy style, Mark's cock punching deep on every stroke, Jake rocking back to meet him. When Mark finally unloaded, he buried himself to the root and pumped thick ropes straight into Jake's guts, filling him until cum leaked out around the shaft. Jake came untouched seconds later, his hole milking the last drops from Mark's still-hard cock.
They stayed joined, breathing hard, Mark's massive dick still twitching deep inside.
