In the dimly lit closet, siblings huddle close, their bodies pressed together. Michelle's breath hitches as she feels her brother's hardness against her. They're both dressed, but the heat is intense. Their father's stern voice echoes, "You mustn't move!" yet Michelle can't help but rub against her brother. His cock twitches, growing harder, and she can feel her panties growing damp. Their bodies move in sync, their breath ragged, as they succumb to their taboo desires.
