In the quiet of an empty home, a brother and sister find themselves alone. Boredom turns into curiosity as they explore each other's bodies with tentative touches. The sister's moan escapes as she feels her brother's hardness against her. They freeze, then resume, their hearts pounding in sync. The brother's hands roam her curves, his fingers finding her wetness. She gasps, her body arching into his touch. Their breaths grow ragged as they give in to their forbidden desires.
