Teenage Twins (1976)

The twin sisters Hope and Prudence share a close and unusual psychic bond that enables them to feel exactly what each of them is feeling. Moreover, Prudence turns out to be the proper vessel needed to invoke a spell from the legendary magic book The Necronomicon that could grant anyone who participates in an appropriate group orgy ritual immortality. This ridiculous H.P. Lovecraft-inspired horror erotic is pure exploitation.

Starring: Brooke Young, Taylor Young, Leo Lovemore, Eric Edwards, Tia von Davis & Todd Davis.
