A straight man, unassuming and alone, begins a seemingly innocent edging session. He strokes his cock, feeling the familiar-building pressure. His body tense, he reaches the brink, but to his surprise, he loses control, and ropes of cum shoot out, catching him off guard. Unwilling to stop now, he powers through, his desire intensifying. He strokes harder, faster, bringing himself to the edge again, and again, cumming multiple times in a relentless, solo marathon.
