Chris Cannon and Jerk Douglas play faculty members of the titular Underground Sex School. They "interview" prospective students and give private lessons at a typical Hollywood country club patio.

Douglas pulls up a lawn chair and gets a rigorous hand job from Layla Jade. Lots of nasty talk from this UK tart, who proves to be scholarship material. Passing over the intermediate level of vaginal penetration, she proceeds directly on to the advanced anal colloquium. In mid-fuck she dismounts and sucks her own butt juice off her professor's cock - a practice no accredited sex school would recommend. She is rewarded with a mouthful of cum as a chaser.

Kerkove takes the same course with Cannon at poolside. He plumbs her gape from several different positions and she displays no hesitation about devouring the stinky thing fresh from the hole.

After such heady precocity, the remaining three students don't seem to apply themselves as earnestly.
