In the dim light of the closet, the amateur siblings stand, their bodies barely inches apart. The sister, haunted by religious guilt, clutches at her brother's arm, her knuckles white. The brother, his cock already hardening, reaches out, tracing the curve of her waist. She gasps, her eyes fluttering closed, and he takes that as his cue, pulling her close, his hands roaming over her body, feeling her soft curves through the thin fabric of her clothing. They stumble, their bodies pressing together, and she can feel his hard cock against her belly. She moans, her resistance fading, and they begin to kiss, their tongues tangling, as they give in to their taboo lust.
