Heiße Nächte auf Schloß Dracula (1978)

A newly-wed couple is lured to Schloss Schreckenstein, the residence of Count Dracula – condemned for all eternity for shagging his grandmother. Soon, Eva is under his spell and is taken away to be the centre of an orgy. The apparent purpose of the exercise is to fill her up with spunk before the Count takes a bite.
