Slumber Party '57 (1977)

Men, even the most worldly of us, are always surprised at the raunchy avidity with which women discuss sex, and that's why Slumber Party '57 (1977) has a built-in audience that includes every breathing heterosexual whose balls have dropped. The story is simple: A clutch of teenage women spend a single night at the tail end of the 1950s at a sleepover in a big house. None of the budding beauties wants to be the first one to nod off, so they stay awake by regaling one another with their cherry-popping tales. Two points that make Slumber Party '57 essential viewing: The picture was shot keeping in mind the giant screen of the drive-in theater, and one of these bragging sexual newcomers is portrayed by Cheryl "Rainbeaux" Smith. You can also see the likes of Mary Ann Appleseth showing her ripe fruit when she makes out with some movie star. A few minutes later you can see her nips again while she gets pelted with produce. You can also get a great view of Janice Karman's gorgeous globes at the 64-minute mark when she takes her blue shirt off with Janice Wood. You'll feel some wood in your pants! If that's not enough to get your rocks off, Noelle North and her booty and breasts can be oogled while she gets a spanking. Cheryl Smith's ass is also on display a mere 12 minutes in as she sexily slithers her way out of a pool. Your little buddy downstairs will awake from its slumber!
