Demon Sex starts with a fun opening narration about Reptoids, Greys, containers, vampires and an ancient astronauts like origin of Humanity. The Greys are known as demons now and the movie's bare plot has something to do with bringing them back through genetic engineering. The plot makes way for extended scenes of strippers, a bloody slapping/choking sex scene that goes on forever, a cute and totally nude girl being sliced up all over (including her cooter!) and then having the blood washed off her in the shower with no wounds showing because she's a witch now for some reason in another very long scene and some more pretty graphic at times nudity, because the film didn't have enough. There's some decent cheap messy gore like torn out throats, torn off kneecaps and a very fake decapitation. There's also the birth of a demon child at the end, this being the second film I watched today with demon child birth (the other being Headhunter). The "star" of this is Brinke Stevens and she's probably one of the less attractive women in this. I'm not really a fan of the more famous screen queens. The film lives up to half of the title, I don't know why they bothered with the demon/aliens part when they obviously just wanted to make a softcore film with sleazy sex scenes. Oh, I should mention this was on that Tomb of Terrors set I'm slogging my way through and while this is abysmal in most ways of normal films it's still better than quite a few films on that set.
