Embrace of the Vampire (1994)

Synopsis
An innocent girl becomes the victim of an ancient curse in this erotic horror story. Charlotte (Alyssa Milano) is a beautiful but chaste college freshman who is nearing her 18th birthday. Charlotte's boyfriend Chris (Harrison Pruett) would like to take their relationship to the next level, but Charlotte isn't sure if she's ready. Meanwhile, Charlotte finds herself aggressively pursued by a mysterious new suitor (Martin Kemp). What Charlotte doesn't know is that she's the reincarnation of a Transylvanian princess (Rebecca Ferratti), and her new friend is a vampire who once loved her. The vampire will be able to retain his powers of eternal life only if he can seduce Charlotte before she turns 18 -- which only gives him three days. To weaken Charlotte's resolve, the vampire arranges for lovely Sarah (Charlotte Lewis) to introduce her to the pleasures of lesbianism. Embrace of the Vampire featured former child star Alyssa Milano in several nude scenes; a large number of internet fan sites began posting frame captures of Milano topless from the film after it was released on home video. Milano and her mother responded by taking legal action against web sites using her images without permission; as a result, she has since pledged not to disrobe onscreen again. ~ Mark Deming, All Movie Guide
