Les Collegiennes (1977)

Two college-aged girls, a blonde and a brunette, kick things off in a garden setting. They’re both slim, with the brunette rocking a casual, sporty look. The action moves indoors, where the guy joins in. He’s a brown-haired, athletic dude who wastes no time unbuttoning his shirt. The blonde lies on the bed, partially nude, while he goes down on her. She returns the favor, giving him a slow, teasing blowjob. The camera gets nice and close, so you see every detail. Later, they switch it up, with the brunette joining in for some shared oral fun. It’s all shot in a cozy bedroom with soft lighting, making it feel intimate and real.
