Snowballing (1975)

It's more fun than skiing!

Two buddies start out on a camping/ski trip that turns into one of the hottest sex trips ever captured on film. Bob and Sam are horny young studs who know just what to do to turn each other on — and they've both got the equipment to do the job right! When they get it on in the great outdoors, they give new meaning to the word "snowball!"
