Hiding in the closet, the siblings' breaths mingle in the confined space. She, a picture of religious devotion, he, her curious and eager pupil. As she recounts her transgressions, her voice grows husky, her eyes dilate. He leans in, drawn to her scent, her warmth.

Their hands roam, seeking, finding, as they give in to their forbidden lust, their bodies pressed together, their moans muffled in the dark.
