A throbbing, uncut cock strains against tight boxers, the fabric tenting with anticipation. A solo male's hand slips inside, stroking the rigid length. Moans escape as he picks up the pace, his cock pulsing with need. The boxers darken, a wet spot forming where the head of his cock leaks pre-cum. The fabric becomes see-through, outlining every vein and contour. With a final, guttural groan, he erupts, cum soaking through the boxers, creating a large, damp stain.
