He never saw it coming. One minute Mark was nursing a beer at the dive bar on the edge of town, the next he was waking up in a stranger's basement with his wrists tied behind his back and his pants yanked down around his ankles. The guy standing over him was huge, built like a linebacker, with a thick black beard and a cock that hung heavy and half-hard between his legs, already bigger than anything Mark had ever seen on a man.
"Look at you, straight boy," the man growled, voice low and rough.
"You came in here acting tough, but your ass is mine now." He grabbed Mark by the hair and forced his face toward that massive cock. "Open up. Suck it."
Mark tried to turn away, but the man slapped his cheek hard and shoved the fat head past his lips. It tasted salty, thick, stretching his mouth wide. "That's it, choke on it," the stranger said, thrusting deeper until Mark gagged. Spit ran down his chin as the cock pushed into his throat, veins pulsing against his tongue. He struggled, but the man held him there, hips pumping slow and deliberate, making him take every inch until his nose pressed against the man's trimmed pubes.
When he finally pulled out, Mark gasped for air, strings of saliva connecting his lips to the glistening shaft. "Please, man, I'm not gay," he rasped. The stranger just laughed and flipped him onto his stomach, kicking his legs apart. Thick fingers shoved between his cheeks, rubbing spit over his hole before one pushed inside. Mark bucked, but the intruder was relentless, working that finger in and out until the muscle gave way, then adding a second, scissoring him open.
"Look at this tight straight hole," the man muttered. "Gonna wreck it with this big cock." He spat on Mark's ass and lined up the massive head. The pressure was brutal. Mark cried out as it breached him, the fat crown popping past the ring and sinking in. Inch after thick inch followed, stretching him wider than he thought possible. Pain flared hot, but the man didn't stop, grinding deeper until his balls rested against Mark's ass.
"Fuck, you're squeezing me so good," the stranger grunted, pulling back and slamming in again. Each thrust forced more of that huge cock inside, pounding against Mark's prostate until sparks of unwanted pleasure mixed with the burn. Mark's own cock, trapped against the floor, started to stiffen despite himself. The man noticed and reached under to stroke it roughly. "Yeah, your dick's getting hard while I fuck you. Knew you'd like taking big cock."
He fucked harder, the wet slap of skin on skin filling the room. Mark's protests turned to groans as the stranger angled his hips to nail that spot over and over. Sweat slicked their bodies. The cock felt endless, dragging along his walls, owning him completely. When the man reached down and twisted Mark's nipples, he arched back into the thrusts without meaning to.
"Take it, slut," the stranger snarled, speeding up. His balls slapped heavily with every drive. Mark felt himself clenching around the thickness, body betraying him as pre-cum leaked from his own dick onto the concrete. The man pulled out suddenly, flipped him onto his back, and shoved back in, hooking Mark's legs over his shoulders to go even deeper. The new angle made Mark shout, the big cock battering his insides.
They stayed locked like that, the stranger pounding relentlessly while jerking Mark's cock in time with his thrusts. "Gonna fill this ass," he warned, voice strained. Mark's orgasm hit first, sudden and intense, ropes of cum shooting across his stomach as his hole spasmed around the invading cock. The man groaned and buried himself to the hilt, flooding Mark's guts with hot, thick loads that leaked out around the shaft.
He didn't pull out right away. Instead he stayed buried, grinding slowly as the last pulses emptied into Mark. When he finally withdrew, cum trickled from the stretched hole. Mark lay there panting, body sore and used, yet strangely satisfied in a way he couldn't explain. The stranger untied his wrists, helped him sit up, and smirked. "You'll be back for more. That ass was made for big cock."
Mark didn't argue. He already knew the man was right.
