Karen, a devout woman, finds herself in a cramped closet with her brother, their bodies pressed together in the dark. She feels his hardness against her thigh, a forbidden stirring that she can't ignore. Her brother, equally tempted, whispers, "We shouldn't..." but his words trail off as Karen's hand finds its way to his zipper. She hesitates, her religious upbringing screaming at her to stop, but her body yearns for more. She frees his throbbing cock, feeling its heat in her hand. He gasps, and she knows he wants this as much as she does. Their bodies move together, their breaths coming in ragged gasps as they give in to their taboo desire.
