A lone man, driven by primal urges, takes matters into his own hands. In the privacy of his room, he strips down, his erection throbbing with anticipation. He strokes his length, his grip tight, his pace steady. The room fills with the sound of his pleasure, his breath coming in ragged gasps. His muscles tense, his abs clench, and with a final, powerful stroke, he erupts, his seed shooting out in thick ropes, painting his chest and hand in a sticky, messy masterpiece.
