In a cramped room, a Mexican couple, driven by curiosity and a wager, decide to record themselves indulging in self-pleasure for their partners' enjoyment. The brother, excited, sets up the camera, catching his sister, a morrita, in all her intimate glory as she touches herself, her breath hitching with each stroke. The moment they think they've captured enough, they stop, unaware that the camera continues to roll, preserving their most private acts for an audience they never intended.
