Eve and the Merman (1965)

Starts on a beach with this slim blonde chick Eve and two hairy dudes—one’s got long brown waves, the other’s a muscular brunette. They look like they just finished surfing, all sunburned and sandy. Cut to Eve in the water, playing with her tits while the waves lap at her waist. Then it’s indoor time: a redhead with long straight hair straps up and makes the brunette dude suck her dildo while Eve watches. Best part? The close-up of the brunette going down on Eve—she’s got her legs spread wide, and he’s really getting in there. Lighting’s all warm and moody, like a sunset filter, so everything looks soft but still dirty.
