Three beautiful guys, one girl, and a motorcycle all meet in the world's first 'trisexual' porno film.

A naked older man cruises around L.A. in his milk truck, picking up hitchhikers and voyeuristically watching the goings-on in the rear.

The classic story of three men, one woman, and a motorcycle, having heterosexual, gay, and man-on-machine sex, with its groundbreaking and climactic tailpipe penetration scene, in an auto repair shop in Los Angeles.
