In the dim light of the closet, the siblings' breaths mingle, their hearts pounding with a shared secret. Michelle's hand trembles as she guides her brother's massive cock to her untouched entrance, her mind racing with taboo thoughts. She lowers herself slowly, gasping at the intense pleasure-pain of her hymen breaking. Their bodies find a rhythm, their moans muffled by their clothes, until they're both teetering on the edge. Michelle's orgasm rips through her, her brother following suit, their fluids mingling as they collapse into each other, their bodies shaking with the weight of their forbidden act.
