My Best Friend Is a Vampire (1988)

High-school kid Jeremy Capella (Robert Sean Leonard) finds his life turned upside down when he sleeps with an exotic older woman (Cecilia Peck) and she turns him into a bloodsucking undead monster in the 1980s comedy My Best Friend Is a Vampire. Suddenly Jeremy is being chased by men he thinks were sent by the woman’s jealous husband but are actually vampire hunters who want to drive a stake through his heart. There’s no skin here, but the sight of lingerie-clad Cecilia Peck will give you a Gregory Pecker!
