Following the living room fuck fest in Part 1, Sandra (the Slut) is carried upstairs by Eric (the Step-Son) accompanied by Harry (the Step-Father). Instead of a nice comfy bed, Sandra is hooked to a rack where Harry can flog her ass and back while Eric fingers her and shoves a vibrating dildo up her cunt. Oddly Sandra seems to enjoy the pleasure and pain combo. What a kinky slut.
