Unbeknownst to her brother, the little sister sneaks into his room, drawn by the scent of his cologne and the memories of their close bond. She lies on his bed, her heart pounding as she lifts her skirt, revealing the innocent white panties that hide her secret. She touches herself, her fingers tracing the damp fabric, her breath hitching as she dares to slip a finger underneath, gasping at the intense sensation. She imagines it's her brother's hand, his touch, and she loses herself in the fantasy, her body arching as she nears the edge of release.
