2. Wild Things (1998)
It starts out as a face-slapping, hair-pulling cat fight in a swimming pool and ends up in a make-out session, complete with bikinis and T-shirts being tossed aside with sultry music in the background. Denise Richards plays the naughty rich girl and Neve Campbell plays the naughty poor girl. Despite coming from opposite sides of the tracks, they manage to get together to concoct some rape accusations against their high school guidance counsellor (Matt Dillon). The fact that this takes place in South Florida makes the whole movie feel even more steamy and tawdry. Wild Things also made our Top 10 Erotic Thrillers list a while back. It's so multipurpose.
