With no one to please but himself, our solo adventurer takes his time, exploring every inch of his erect cock with greedy fingers. He starts slow, teasing the sensitive head, smearing the beads of pre-cum that form at the tip. His hand moves down, gripping the shaft firmly, pumping with increasing speed. His other hand cups his balls, massaging gently, sending waves of pleasure coursing through him. His body tenses, his abs contract, and with a final, deep moan, he comes undone, his cum shooting out in thick streams, coating his hand and dripping onto the floor, a mess he'll clean up later, with a satisfied smile.
