Swinging Ski Girls (1975)

One of the girls has long blonde hair and a slim body — she’s the first to blow the guy in the bathroom, deep throating with her head bouncing fast. They move to a dim bedroom, where the second girl, also blonde and slim, rides him facing away in doggy style, then flips around for missionary. The guy cums on her stomach after pulling out — thick load, multiple spurts. Later, both girls are outside in ski jackets and nothing else, leaning on a concrete barrier with mountains in the background. Not much talking, just straightforward porn with decent lighting on the sex parts. Camera stays close during oral and creampie.
