Sisters Theresa Lynn and J.J. North are crazy for cock in Psycho Sisters (1998). Actually, they’re crazy to cut off your cock and put it in a mason jar. It all goes back to when they witnessed the assault and murder of their sister. They promptly went nuts and ended up in the care of a psychiatrist who was a little too quick to declare them cured. Now they’re busy whacking the tallywhackers of unfortunate young men. But if you think that’s a crime, check out how Tina Krause keeps her clothes on throughout this film. Fortunately, Theresa and J.J. show off their talents, as does Kris Burtt as their unfortunate sibling.
