Trapped alone in his apartment with nothing but his imagination and a steady supply of lube, a horny man embarks on a marathon masturbation session. His solid, veiny penis never softens, as he strokes and teases it, watching it grow even larger and more engorged. He dreams of faceless lovers, their bodies entwined with his, their moans echoing in his mind. After hours of relentless self-pleasure, his balls tighten, his cock swells, and with a final, shuddering thrust, he spills his pent-up seed, a torrent of cum jetting from his cock, coating his hand and belly in a slick, milky puddle.
