A Smell of Honey, a Swallow of Brine (1966)
Short-haired brunette and a long-haired blonde team up in this threesome. Both girls are slim and petite, early 20s type. They start by going down on each other while the guy watches from the background. The camera gets super close during the oral parts, so you can see everything. Later, the brunette sucks him off in a car with mountains in the background — it’s a unique outdoor setup. The scene switches between indoor and outdoor, keeping it interesting. Solid variety of positions and angles throughout.
