Sent to look for a cure for the demonic trance the Devil Dolls have over Batwoman, super sisters Amber and Ruby soon find themselves in their own precarious predicament. While searching for clues they come across the curious box DeSade. Before Ruby has time to scan it for information, Amber brazenly opens it setting loose a strange red smoke. She quickly shuts it, but it might be too late! The diabolically seductive smoke seems to have a dastardly effect on it's victims, making them lust after the first person they see. In this case the super sisters become impassioned for each other, falling into an erotic frenzy and tearing one another's costumes off. Unable to keep their hands off, they soon find themselves in a mindless tangle of wet tongues, fingers and pleasure. These two heroines are taking sisterly love to and entirely orgasmic level.
