Miss Laid Lovers (1978)
This one’s all about tight spaces and tight bodies. Two brunettes, one white, one with curly hair, both in their 20s, team up on a muscular white dude on a yacht. The bedroom scene starts with a blowjob, close-up so you see every bit of it. Dim lighting sets the mood as they move into doggy style, the curvy one taking it deep while her friend watches. There’s a lot of kissing and embracing between the girls, and the guy gets involved too. The slim brunette rides him later, her long hair down her back. It’s all indoor, all intimate, with a mix of medium shots and close-ups to keep it interesting.
