Nefele y las seductoras de lesbos (1980)

Guy with short blonde hair and a tight build gets blown by two young women with long brown hair — both slim, both wearing barely anything. The blowjob starts in a dim bedroom, close-up on one girl choking herself on his dick while the other strokes him and kisses her neck. They move to a couch in what looks like a living room, wide shot showing the full layout — coffee table, lamp, messy cushions — and both girls take turns riding him and going at him from behind. One brunette gets fucked doggy style while the other watches, then switches in for missionary with lots of grinding. Camera stays wide for most of the group sex, no shaky close-ups — you see their faces, bodies, how they switch positions without stopping. Last few shots show the guy jerking off alone on a bed, then later reading at a desk like nothing happened.
