Savage Weekend (1979)

Tapping into the slasher movie craze of the 1970’s and 1980’s, Savage Weekend (1979) follows the formula with a few twists. When several couples head out to the country for a weekend where they plan to drink, eat good food, have sex, and check out a boat that is being built, all seems perfect. Until a masked mystery killer beings taking them out one by one.

First we get some naked, sweaty sidage from  Devin Goldenberg as he drives his rod into a woman from behind. A little later he strips off his shorts, letting us see the twig and berries, before he crawls on top of a woman who is sunbathing and gets his freak on with her while another guy hides in the woods and watches.
