Insemination, the deliberate introduction of semen, defines the essence of bareback fucking, the sharing of seed between men, the most intimate moment in mansex. Following up to Spunk's smash hit Insemination, director Gary Carlton brought six couples together, and with his minimalist directing style, captured the lust of the moment in which a top injects his bottom with sperm. Each pairing demonstrates the fucking frenzy leading up to that powerful ejaculation, the grunts and groans of the top, the moans and prolonged, often inarticulate, sounds the bottom utters, knowing his guts are filling up with manseed, as a throbbing cock slides deep inside.
