The Ax Master(1977)

Super-bodied Don Talon is a man's man, if there ever was one! Roughing it in the redwoods with a couple of 19-year-olds, Talon rises early and goes off to chop wood for their campfire. When he returns with the firewood, Talon discovers his young charges relieving one another's hard-ons. Feigning anger, the burly stud drags the naked duo from their tent; but instead of getting on their case, he gets into the action himself, for a blistering session of might and submission. A trip to the woods you'll not soon forget!
