In the dimly lit room, the rhythmic hum of the stationary bike sets the tone for this solo session. The rider's thick cock bobs with each pedal stroke, his hand wrapping around the engorged shaft. Precum beads at the tip, a testament to his growing excitement. His pace quickens, his grunts filling the room as he nears his climax. With a final, powerful thrust, he erupts, his cock pulsing as he coats his hand and abs with his hot, sticky load.
