Mark spotted the guy across the crowded bar and knew he had to have him. Tall, broad shoulders, thick arms, and a bulge that said he was packing serious meat. No small talk needed. Mark walked straight over, grabbed the guy's wrist, and said, "My cock's hard and your mouth looks like it needs filling. Back room. Now."
The guy, built like a fucking truck and named Derek, didn't hesitate. He followed Mark past the bar and into the dim hallway that led to the storage area. The door clicked shut behind them. Derek shoved Mark against the wall first, their mouths crashing together, tongues pushing deep while hands ripped at belts and zippers.
"Fuck, get my dick out," Derek growled. Mark dropped to his knees on the concrete floor, yanked Derek's jeans down, and freed a fat, veiny cock already leaking. He wrapped his lips around the head and sucked hard, tasting salt and heat. Derek's hands clamped on Mark's head and thrust forward, shoving half that thick shaft straight into his throat.
Mark gagged but kept sucking, spit running down his chin as Derek face-fucked him in steady strokes. "Take it all, yeah, choke on that cock," Derek muttered. Mark reached up, grabbed Derek's heavy balls, and tugged while his tongue worked the underside of the shaft. Derek pulled out, strings of spit connecting them, then hauled Mark up and spun him around.
Mark braced against a stack of crates. Derek yanked his pants down to his thighs, spit on his fingers, and shoved two straight into Mark's hole. "Tight fucking ass. Gonna wreck it." He worked them in and out fast, then added a third, stretching Mark open with rough twists. Mark pushed back, grunting, "Do it. Fuck me raw."
Derek lined up his cock and drove in with one hard thrust. Mark's hole stretched around that thick dick, burning and full. Derek didn't pause; he started pounding, hips slapping loud against Mark's ass, balls swinging. Every stroke went balls-deep, the head punching Mark's prostate until his own cock leaked steadily onto the floor.
"Harder, fuck me like you mean it," Mark snarled. Derek grabbed his hips and slammed in faster, the wet sound of skin on skin filling the room. He reached around, wrapped a fist around Mark's cock, and jerked it in time with his thrusts. Mark came first, shooting thick ropes across the crates while his ass clenched tight around Derek's dick.
Derek didn't stop. He kept fucking through the spasms, then pulled out, flipped Mark onto his back on the crates, and shoved back in. Legs over Derek's shoulders, Mark took every inch again while Derek leaned down and bit his neck. "Gonna fill this hole," Derek said, voice rough. He hammered faster, sweat dripping, until his cock swelled and he unloaded deep, pumping cum in heavy pulses that Mark felt flooding inside him.
They didn't leave right away. Derek stayed buried, slowly thrusting through the mess, keeping Mark hard again. Round two started with Mark on his knees sucking the cum and ass taste off Derek's cock until it stiffened once more. Derek bent him over again, this time slower but still deep, grinding against his prostate until Mark shot a second load onto the floor. Derek followed, adding another hot flood inside him.

By the time they pulled apart, both were dripping and spent, breathing hard. Mark wiped his mouth, pulled his pants up, and grinned. "Same time tomorrow." Derek just nodded, already tucking his cock away, both of them knowing the night had only started.
