Heterosexual womanizer: Kimberly Sterling’s brief seductive scene with a young virgin step-sister

Kimberly Sterling as the sl__y seductress steps out and takes her friend’s innocent stepsister for a spin. Seduction starts in their bedroom and the audience is exposed to the girl’s sexuality, forbidden in the film. They both reach an orgasm together and such a beautiful interchangeability of the friend and the lover kind of makes little sense.
