The garage smelled like motor oil and sweat when Jake walked in, his jeans already tight from the heat. He was looking for a quick fix on his truck, but the mechanic, a thick-built guy named Marcus with grease on his hands and a smirk on his face, had other ideas. "You need more than an oil change, don't you?" Marcus said, wiping his palms on a rag before stepping close. His voice was low and rough, no bullshit.
Jake didn't answer with words. He grabbed Marcus by the belt and yanked him in, their mouths crashing together hard. Tongues shoved deep, teeth clacking, spit mixing fast. Marcus's hand went straight to Jake's crotch, squeezing the hard cock straining against denim. "Fuck, that's a thick one," he growled, popping the button and yanking the zipper down. Jake's cock sprang out, heavy and leaking at the tip. Marcus dropped to his knees right there on the concrete floor and swallowed it in one go.
The wet heat of Marcus's mouth hit like fire.

He sucked hard, cheeks hollowing, tongue swirling under the head before taking it to the back of his throat. Gagging noises filled the garage as he worked it, spit running down Jake's balls. Jake thrust forward, fucking that mouth, hands gripping Marcus's short hair. "Suck it deeper, you dirty cocksucker," Jake grunted. Marcus moaned around the shaft, eyes watering but not stopping, one hand jerking the base while the other reached down to free his own cock.
Marcus stood up after a minute, lips shiny with spit. "Bend over the hood," he ordered, voice thick. Jake turned, shoving his jeans down to his thighs, ass exposed. Marcus spat on his fingers and pushed two straight into Jake's hole, no slow warm-up. The stretch burned good, fingers twisting and pumping, scissoring that tight ring open. Jake pushed back against them, cock throbbing against the warm metal of the truck. "More, fuck me already," he demanded.
Marcus didn't need telling twice. He lined up his fat cock, head slick with precum, and shoved in balls-deep in one thrust. Jake groaned loud, the sudden fullness making his legs shake. Marcus started pounding right away, hips slapping against Jake's ass with wet, filthy sounds. Each thrust dragged over that spot inside, making Jake's cock drip onto the floor. "Take that dick, yeah, your hole's gripping me like it wants to keep it," Marcus rasped, gripping Jake's hips hard enough to bruise. He fucked like he meant it, deep and fast, skin slapping, sweat dripping.
They switched after a while, Jake flipping around to face him. Marcus lifted one of Jake's legs over his shoulder and slammed back in, the new angle letting him go even deeper. Jake jerked his own cock in time with the thrusts, precum making his fist slide easy. "I'm gonna fill this ass," Marcus warned, pace getting erratic. Jake nodded, eyes locked on him. "Do it, breed me." Marcus buried himself to the root and came hard, hot pulses flooding Jake's insides, some leaking out around the shaft.
Marcus pulled out slow, cum dripping down Jake's thighs. But Jake wasn't done. He pushed Marcus back against the workbench, dropped down, and sucked that softening cock clean, tasting his own ass and Marcus's load mixed together. It got hard again quick. Jake stood, spun Marcus around, and returned the favor, spitting on his own cock before driving into Marcus's hole. It was tighter than expected, gripping every inch. Jake fucked him raw and relentless, one hand reaching around to stroke Marcus's cock. "You like getting used too, huh?" Jake said through gritted teeth. Marcus just pushed back, grunting every time Jake bottomed out.
They came again like that, Jake unloading deep while Marcus shot across the workbench. Afterward they stood there catching breath, cum and sweat cooling on skin. Marcus grabbed a rag, wiped them both down rough, then pulled Jake in for one more slow, filthy kiss. "Come back tomorrow for that tune-up," he said with a grin. Jake nodded, already thinking about round three, jeans pulled up but the ache in his ass promising more. The garage door rolled down behind them as they headed out, the night still young and both of them hungry for whatever came next.
