Seated on the edge of his bed, our solo adventurer starts slow, teasing his length with gentle touches. His eyes flutter closed, imagining a lover's touch. His strokes become faster, more urgent, his breath coming in short gasps. His free hand reaches down, cupping his heavy balls, rolling them gently. The tension builds, coiling in his core, and with a final, desperate tug, he finds his release, his body convulsing as he paints his chest with his warm, sticky seed.
