In a house of religious constraints, two sisters find solace in secret masturbation. They don't mean to, but their sessions escalate into a game of gapping their tight cunts, filling the air with their moans and the scent of their arousal. The site of their sin is a cramped closet, where they squeeze in, their semi-clothed forms pressed together. Their father's voice echoes in their minds, "You mustn't move!" Yet, their bodies betray them, lubrication soaking their siblings' penises as they slowly sink down, rubbing their untouched vaginas along the hard cocks.
