Billy (credited as Quirky) and Milo think they're just going to the dungeon owned by Mistress Shaydee and Sabrina Belladonna for a quick fuck, 'cause they're your typical lame-ass, sex-starved straight boys. Once there, they quickly find out that the women had "something more esoteric in mind" - like starting off with a bit of light flogging and a spanking with a spiky hairbrush until they're prepared for "the next level of bitchdom."
That next level proves to be quite some jump. Shaydee pairs up with Milo, lights a torch and burns the hair off his back and legs. He takes it well, so she play-pierces his nipples and penis with a multitude of needles (and then removes them; the best part!). While the tears in Milo's eyes are captured for posterity (good), there's no close-up of Shaydee's blood-drenched handiwork as they're removed (very bad).
Billy goes through his changes with Belladonna's excellent CBT. She grabs his nuts and twists delightfully, crushes them beneath her boot, lifts and separates them with a length of cord (then attached to his feet, so he's a party to his own torment), and grips his terrified little dick with a pair of rubber-tipped tongs, pulling hard as his moans increase.
