Caged Virgins (1972)

Still sporting their clown costumes, Michelle and Marie, two virginal women on the run, flee a New Year's party in a stolen car. As the young runaways wander the picturesque French countryside in search of safety, before long, they chance upon the decrepit château of a centuries-old vampire king and, unaware of the risks involved, enter the castle. But there, torture, sadism, and sexual abuse await the eternally lost girls. Now, the only thing that matters is submitting to the will of the pitiless lord. Who can escape the intoxicating pleasure of pain and the evil master's harem of vampiric vixens?
