In the dim light of the closet, brother and sister find solace in each other's arms, their bodies entwined in a dance of lust and longing. She grinds against him, feeling his hardness through their clothes, while he kisses her neck, his hands roaming her body, squeezing her breasts, slipping under her panties to find her soaking wet. They strip each other slowly, their eyes locked, their breaths mingling. He enters her, filling her completely, and they move together, their bodies slapping, their moans echoing in the small space. It's wrong, they know, but it feels so right.
