Horny and alone in her sister-in-law's empty room, a curious woman can't resist the urge to touch herself. She strokes her clit, imagining her sister-in-law's husband watching her, his thick cock hard for her. Her fingers delve deeper, fucking herself as she thinks about his hands on her body. She's so lost in her fantasy that she doesn't hear the front door open, or the footsteps coming closer.
