The siblings huddle together in the tiny closet, their bodies barely contained within the narrow space. Michelle's breath hitches as she feels her brother's erection pressing against her thigh. She looks up at him, his eyes filled with a mix of guilt and desire. She tentatively reaches out, her hand brushing against his hardness. He sucks in a sharp breath, his body tensing. She continues to stroke him through his pants, feeling his length pulse with need. He leans down, his lips barely brushing against hers, as they both struggle against their taboo desires.
