Penthouse Variations Magazine: Variations is an adult entertainment magazine featuring erotic and sexually explicit content. Every issue presents readers with the outrageous and exciting tales of real-life lovers. The submitted stories never fail to be on the edge and red-hot in nature, and often can be considered over the top from what many are used to reading in pornographic publications. Variations is a spin-off magazine from Penthouse, and differs in that the content focuses on racier sexual topics than its more mainstream mother publication.
