Billy stripped out of his jockstrap, leaving it crumpled in a pile of his sweat-soaked gear on the floor. When he returned from his shower, a mountain of a man was holding the jockstrap to his face as he inhaled the musky scent. "That's mine," Billy squeaked, a tremor of fear in his voice. With a predatory grin, the man replied "It smells like a dirty boy," he growled, "and dirty boys get cleaned." He didn't just pull Billy back to the showers; he dragged, throwing him onto the slick, wet tiles. The "washing" was brutal, the man's thick, soapy fingers violating Billy's asshole, twisting and plunging as Billy begged. "I'll wash it! I promise I'll keep it clean!" he sobbed. The man laughed, a deep, menacing sound, and then Billy felt it. The man's massive cockhead slammed against his clenched hole, forcing its way in. He didn't just fuck Billy, he impaled him, driving Billy into the tile with every brutal thrust, using his ass like a cheap fleshlight. With a final, guttural roar, the man unloaded what felt like a gallon of hot cum deep into Billy's asshole. He pulled out with a wet, sucking pop, and without a backward glance, scooped Billy's soiled jockstrap from the floor, wiped his filthy cock on it, and walked away.
