Confined to a tiny closet for punishment, two siblings find themselves alone and horny. He's thinking about her, she's thinking about him, and the cramped space only intensifies their desire. She reaches out, touching his hardening cock through his pants, making him gasp. He reciprocates, his fingers finding her wetness over her panties. Their breathing grows heavy, their bodies flush against each other. They're about to go all the way when their dad walks in, catching them in the act and leaving them breathless and guilty.
