Frankie and Joanie (1991)

The beautiful Deidre does only a lesbian scene here with Alyssa Jarreaux and it's really hot: first of all, the babes are all natural and not toy boys enhanced Frankestein monsters, they complete each other well (Deidre is always in charge and Alyssa lets go), they use the best position (69). Thus it's steamy because it looks true, not fake.
