Their parents' voices echo from downstairs, oblivious to the sinful dance unfolding in the closet. Michelle's hand trembles as she unzips her brother's pants, his cock springing free, hard and eager.

He reaches out, tentatively touching Michelle's breast through her shirt. Their breaths sync, ragged and hot, as they teeter on the edge of no return.
