The tiled walls of the bathroom amplify the sound of his ragged breathing as he wraps his large hand around his stiff, aching cock. The sight of his thick, veiny shaft disappearing into his fist sends a jolt of pleasure through him. He picks up the pace, his grip tightening as he pumps his dick with increasing urgency. The scent of his pre-cum fills the small space, a heady aroma that only serves to fuel his desire. His balls tighten, and with a guttural moan, he spills his load, his cock throbbing as it paints the bathroom wall with ropes of hot, white cum.
