Crucible of Horror (1969)

Crucible of Horror (1971) aka The Corpse, is a British psychological thriller about a sadistic husband and father who plays cruel mental and physical games with his family. When the mother and daughter (Sharon Gurney) have finally decided that they've had enough, they turn the tables on this brutal bully and give him a taste of his own medicine.  Before the revenge plot kicks in, we get some nice looks at the luscious young Sharon Gurney in several compromising positions. In one particularly barbaric scene, the father takes her out by the lake and humiliates her, making her strip nude and run through the water. We get a nice view of her big ol' booty and breasts in the screen caps below, and there's also another long look at her lobbers as she changes out of her nightgown in the third pic. Crucible of Horror will make you as stiff as a corpse!
