El último amor en Tierra del Fuego (1979)

Starts with this older guy—gray hair, mustache, looks like your uncle who grills too much—standing in a living room with two girls. One’s a skinny blonde in her early 20s, the other’s a goth chick with black hair and tits spilling out of her top. The blonde drops to her knees and goes to town on his cock while the goth girl presses up against him from behind, playing with his chest. You get a solid side view of the blowjob, so you see her lips stretching around him and her hand jerking the base. Later, the goth chick takes over, bending over a couch while the older dude pounds her from behind. The blonde joins in, riding his face for a bit, then they switch it up again. Camera work’s decent—nothing fancy, but you get close-ups of the action without missing the full picture. Feels like a chill hangout that just happens to involve a lot of sex.
