Hidden in the closet, brother and sister succumb to their secret longing. The room is cramped, their bodies pressed together, hearts pounding. Her breath hitches as his hands roam, cupping her breasts, squeezing her ass. She can feel his erection pressing against her, straining against his pants. Their lips meet in a hungry, desperate kiss, tongues dueling. She reaches down, stroking his length through the fabric, feeling him grow harder. He responds by sliding his hand into her panties, his fingers finding her clit, rubbing in circles until she's writhing against him, her juices soaking his hand.
