The walls of the apartment thin, the neighbor's voice echoes, a symphony of profanity and pleasure as he jerks his throbbing cock with abandon. His grip is firm, his rhythm relentless, his body flexing with each stroke. His cock, a thick, veiny beast, leaks copious amounts of pre-cum, a sign of his intense arousal. As he nears the edge, his voice grows louder, his words more heated, until finally, with a roar, he comes, his cock pulsing as it coats his hand and the floor with his hot, sticky cum.
