Hidden away in the dark, the siblings cling to each other, their bodies heat rising as they try to suppress their growing lust. Michelle's hands tremble as she reaches out, tentatively touching her brother's hardness through his clothes. He gasps, his hips bucking slightly, and Michelle feels a surge of power. She leans in, her breath hot on his ear, "We shouldn't," she whispers, even as her hand begins to stroke him through the fabric. Their bodies move in sync, their breaths coming in ragged gasps, as they teeter on the edge of taboo, ready to plunge into the depths of their forbidden passion.
