In the confines of their shared closet, the siblings find solace in each other's company, their bodies pressed together for warmth. The brother, a virginal teen, can't help but feel his sister's soft curves against him. His cock hardens, pressing against his sister's thigh. She looks at him, her eyes filled with a mix of fear and desire. She reaches out, tentatively touching his hard cock through his pants. He gasps, his body tensing with pleasure. She bites her lip, her hand moving up and down his length, exploring his newfound pleasure.
