A brother and sister, both horny and frustrated, find themselves alone in the house. She retreats to her room, craving release. Her fingers dance over her clit, and she imagines it's his touch, his cock filling her. He, too, is in his room, stroking his hard dick, thinking of her. Their shared lust is a tangible force, a current that flows between them. They both know it's wrong, but they can't deny the pull they feel towards each other. The question is, will they give in to their desires, or will they resist the temptation that's been simmering between them?
