In the dim light of the closet, siblings huddle, their breath heavy with anticipation. Michelle's hand trembles as she reaches for her brother's zipper, revealing his throbbing cock. Their eyes meet, guilt and desire warring in their depths. They've been taught to resist, but their bodies betray them. Michelle's pussy aches as she strokes her brother, feeling his length pulse in her hand. He groans, his hips bucking, as she guides him to her entrance, both knowing they're about to shatter their world.
