Straight, muscular hunk, Genius540, gets lonely and decides to take matters into his own hands. Alone in his room, he strips down to his boxers, revealing a massive bulge. He strokes his thick, veiny cock through the fabric, feeling it throb with anticipation. With a growl, he frees his mammoth dick, jerking it with urgency. His big hands struggle to wrap around his girth as he pumps furiously, his abs clenching with each thrust. The room fills with the wet sounds of his eager strokes, his breath coming in ragged gasps. He leans back, legs spread, and attacks his cock with renewed vigor, his hips lifting off the bed. His body tenses, and with a final, powerful stroke, he unloads, his hot cum spilling onto his abs and chest.
