In the dim light of the closet, the siblings' eyes meet, and they know they've crossed a line. Michelle guides her brother's cock to her entrance, and he pushes in, his thickness stretching her virgin pussy. They move in sync, their bodies pressed together, their breaths ragged. Michelle's hands roam her brother's chest, her nails digging into his skin as he hits her G-spot. They come simultaneously, their bodies shaking with the force of their orgasms. As they catch their breath, they realize they've become each other's secret, their taboo lust binding them together.
