In the heart of an uncharted jungle, Tarzan and Cayne, two bare-skinned beauties, stumble upon an ancient artifact. As they study it, the artifact's magic begins to stir their loins. Cayne's nipples harden, and she feels a strange warmth between her legs. Tarzan's cock twitches, growing stiff in his primitive loincloth. They look at each other, confusion and curiosity mixing in their eyes. The artifact's power compels them to explore their newfound desires, leading to a passionate, carnal lesson in the art of fucking.
