Mated with the golden alien, Romulus, Garnet gets more than she bargained for when she learns the wealthy sex slave merchant has a clone, Remus, whom she is also expected to service.
Aghast at first, Garnet soon learns the advantage of menage a trots with the two identical aliens. Still, she wants her mate for her own. Remus begins to feel left out, so Romulus gifts him with a eunuch sex slave.
Garnet and her alien mate find joy...an boundless pleasure on Obsidian, as its prince attempts to curb some of the practices that Earthlings have brought with them to the Pleasure Planet.
