The pounding rhythm of the gym's music pulsates through the walls, resonating with the solo stud's pounding fist. His massive cock, a testament to his virility, is a sight to behold as it disappears into his powerful grip. The cramped toilet stall, with its stark fluorescent light, offers little privacy, yet he continues, his lust-driven need outweighing caution. His balls tighten, his body tenses, and with a guttural groan, he releases his pent-up load, painting the toilet wall with his hot, sticky seed.
