A lone male, hidden from the world, loses himself in the throes of self-pleasure. His firm grip slides up and down his engorged shaft, coaxing a bead of pre-cum to form at the tip. He leans back, eyes closed, and imagines a lover's touch as he increases his pace, his breath hitching with each stroke. His body tenses, and with a final, desperate tug, he spills his load, gasping in satisfaction.
