In the bustling streets of Monterrey, a brother and sister, strangers to each other until recently, find themselves alone in their apartment, a six-pack of Ale their only companion. As they drink, they grow closer, their eyes lingering on each other. The sister, a wild child, dares her brother to play a game, their hands brushing as they reach for the cards. The tension builds, their bodies inches apart, the Ale fueling their courage. They play truth or dare, the questions becoming more intimate, the dares more daring. Until finally, the inevitable happens, and they're entangled in a dance of taboo lust.
