Michelle, a religious girl haunted by guilt, finds herself alone with her stepbrother in their cramped closet. As they squeeze together, she feels his hardness pressing against her. "You mustn't move," he whispers, but Michelle's curiosity and desire are too strong. She reaches out, touching his cock through his pants, feeling it throb. Her brother gasps, and Michelle, empowered, begins to rub him, her own lust growing as she dares to explore her taboo fantasies.
