In the quiet of their empty home, a curious sister can't resist exploring her own body. She slips off her clothes, her fingers tracing the curves of her young, firm flesh. Her mind wanders, filled with forbidden thoughts. She's alone, but the house feels alive with possibility. Her touch becomes more insistent, her breath ragged as she imagines hands other than her own caressing her skin. The creaking of the floorboards breaks her trance, and she quickly hides her nakedness, hoping her brother hasn't caught her in her private moment.
