A lone, horny man, lost in his thoughts, finds solace in the throes of self-pleasure. His hand wraps around his rock-hard dick, already leaking pre-cum. He strokes it firmly, feeling the pulse of his heartbeat in his engorged member. The room fills with the wet sound of his hand gliding up and down his shaft, faster and faster. His breath hitches as he feels the pending explosion, his body tensing, ready to release a torrent of sticky, white cum.
