In the dim light of an empty house, a brother and sister, drawn together by curiosity and hormones, explore their forbidden desires. She teases him, her body barely concealed in a silk robe, while he struggles to maintain composure, his cock tenting his pants. Their kisses deepen, hands roaming, until she guides him to her waiting, wet pussy. He slides in, filling her, as they fuck in silence, their bodies slapping together, until they climax together, biting back moans.
