In the quiet of her room, a curious sister explores her body, fingers dancing over her clit, legs spreading to welcome a tentative touch.

Flustered, she covers up, but the sight of his shocked face ignites an unexpected thrill. She watches him leave, her heart pounding, her pussy throbbing with an unfamiliar hunger.
