Rossybologna's sister can't resist the urge to touch herself, even with her brother just a wall away. She slips her hand into her panties, her fingers finding her clit and rubbing in slow circles. Her moans are soft, but she worries he'll hear, making her even more aroused. She pictures him joining her, his hands replacing hers, his cock filling her. The fantasy pushes her over the edge, her body shuddering as she comes, her pussy pulsing with pleasure.
