Venus Vixen and Nicky Rebel, left alone and unwanted, retreat into their own minds, each creating a free-use fantasy world. Venus, ignored and unfulfilled, explores her pussy with eager fingers, while Nicky strokes his straight, huge cock, lost in thoughts of using his step-sis anytime, anyplace. As they catch each other in the act, their fantasies intertwine, merging into a world where they're always ready, always available, fucking whenever the urge strikes. Venus's tight cunt aches for Nicky's massive dick, and he hungers to plunge into her, satisfying them both in endless, taboo encounters.
