In the dim light, the siblings' bodies press together, their hearts pounding in unison. The girl's slender fingers trace the length of her brother's untouched cock, making it twitch and throb. He, in turn, tentatively explores her tight, untouched cunt, his fingers slipping through her virgin folds. Their first time is a feverish, urgent joining, their bodies moving in sync, their eyes locked, and their breaths mingling. As they reach their peak, they cry out together, their voices echoing in the closet, a testament to their taboo union.
