Kate Kennedy loves BDSM dates with her insatiable sadist fiance Ramon. She often suffers spanking of her perfect round ass. Sometimes she likes a strap wrapped around her throat making it difficult for her to breathe during sex. One day, Ramon was more than surprised to hear a voice on the other end of the line claiming that he was Kate’s half-sister – Febby Twigs. He is even more surprised and dismayed when Febby enters his workshop in a depraved outfit, demanding money for cheating Kate. When Ramon no longer knows what to believe, he brings Febby to her knees and tries to wrest the truth out of her. But Febby is a tricky slut and she enjoys his cock in her throat and in her pussy. It’s only when Ramon finally ties her up with an intricate shibari tie and starts shoving his huge cock up her ass that she realizes what problems she and her sister really have. Febby tries to resist his interrogation, but Ramon constantly hits her with a stick on her hot body, and then fucks her in the ass, bringing her to screaming orgasms. Ramon punishes both Kate and her sister with squirt-restrained orgasms, zippers, whipping and hot wax.
