In the dim light of the closet, the siblings' bodies press together, their hearts pounding in sync. Michelle's hands roam, tracing the muscles of her brother's chest, her fingers brushing against his erection, making him gasp. He responds by cupping her breasts, his thumbs teasing her hardening nipples through her thin shirt. Their breaths grow ragged as they lose themselves in the moment, their bodies moving in rhythm, their hands exploring, their lips tasting. When Michelle guides her brother's hand under her skirt, they both know there's no turning back.
