A brother and sister, both in their early twenties, find themselves in a motel in Puebla, far from the watchful eyes of their parents. The room is simple, the air thick with anticipation. They start to explore each other's bodies, their inhibitions melting away with each touch. The sister's nipples harden under her brother's fingers, and he can feel her wetness growing as he strokes her through her panties. Their lovemaking is intense, passionate, and filled with the desperation of two people who know they're playing with fire.
