Carlos, a young man with a penchant for the taboo, finds himself alone with his stepmother Marifer, who's been eyeing him lustfully. She's a nymphomaniac, and today she's set her sights on him. Wearing his favorite leather jacket, Carlos tries to keep his distance, but Marifer's persistence is irresistible. She teases him, running her hands over the jacket, her breath hot on his neck. Carlos' jacket becomes a symbol of his resistance, but as Marifer unzips it, revealing his heaving chest, he knows he's lost. The jacket hits the floor, and so does his self-control.
