After a few minutes' recap from Parts 1 and 2, where we are reminded that the aliens' mission on earth is to find suitable women to impregnate, we pick up with the alien-infested Nick Long still deciding whether the smashing-looking Kerri Downs is a fit candidate for alien motherhood. (Downs looks absolutely great with those big glasses and her hair in a bun. She should do this more often.)
Look for lots of clothespins on the nipples and labia, an electric shock device and more before Long puts Downs in a tub and attaches devices that pump fluid into her mouth and pussy. Then his true alien nature is revealed, as he forces Downs to suck his red-and-blue impregnator, which deposits a surfeit of white liquid in her mouth. The inadvertently funny ending has Long wrapping Downs up in clear plastic so she'll keep until he returns. This whole series has been at least interesting for bondage and sci-fi fans, if not erotic for the multitudes (who shouldn't try any of the acts seen here at home). The whole series is worth checking out — and retailers with bondage clientele should stock all three.
