In the dim light of the closet, the siblings' breath comes in ragged gasps. Michelle's hand trembles as she guides her brother's cock to her entrance. She's never felt so wicked, so alive. Her brother's eyes widen as he feels her heat, her wetness. They move slowly, cautiously, each thrust pushing them deeper into forbidden territory. Michelle bites her lip to stifle a moan, her body tensing as she nears orgasm. Her brother follows, his cock pulsing inside her as they both fall into a guilty, panting silence.
