In the dim light of the closet, Michelle and her brother huddle together, their bodies pressed close. Michelle's hand trembles as she guides her brother's cock to her entrance. "You mustn't move," their father's voice echoes in their minds, but their bodies betray them, lubrication coating their skin as they begin to move. Michelle's tight pussy stretches to accommodate her brother's size, their breaths coming in ragged gasps. They fuck silently, their bodies communicating what their lips cannot, until their climax crashes over them, leaving them spent and ashamed, their secret sin tainting their pure, religious upbringing.
