La dérobade (1979)

Starts in this dim, pink-lit lounge with a blonde and a brunette standing close to two guys. The blonde’s got shoulder-length wavy hair and a tight, petite frame—she’s the first to drop to her knees. You see her take one guy’s cock in her mouth while the other stands right next to her, waiting his turn. The camera’s angled just right so you get a clear shot of her lips sliding up and down, no awkward cuts. Later, the brunette joins in, and they switch it up—one girl riding while the other gets pounded from behind. The lighting’s low but you still catch every detail, especially when they’re both on their knees in front of the couch. No crazy positions, just solid, no-frills group action with two girls who actually look like they’re into it.
