A brother and sister, trapped in a tiny closet, succumb to their taboo desires. The sister, haunted by religious guilt, can't resist her brother's growing erection. She guides him inside her, wincing at the initial pain, then moaning as pleasure takes over. He grabs her hips, pulling her onto his cock as they fuck silently, their bodies straining against each other. Their father's voice echoes in their minds, but they can't stop. They come together, their bodies shaking with release and shame.
