Les Suçeuses de mâles (1982)
Two slim blonde girls in their 20s take turns sucking the same guy dick, both outside by a pool and inside a room. The oral work is relentless — deep throat, sloppy lip action, one of them even strokes him while the other gags on his shaft. Camera stays tight on the faces and dicksucking, lots of visible spit, throat flexing. One blonde has short hair, barely any pubes, and a tighter face — she takes more dick deeper. The other has slightly longer hair, fuller lips, and likes to tease before swallowing the cock. They switch off, sometimes both go down on him at once, cheeks squished together. Outdoors scene happens on a pool deck in daylight, wide shot shows the lounge chairs and clear sky before cutting back to tight oral close-ups.
