In the dim light, Michelle's eyes widen as she sees her stepbrother's thick, veined cock for the first time. She tentatively reaches out, wrapping her small hand around the shaft, feeling its heat and pulsating life. He grows harder in her hand, and she can't help but imagine how it would feel stretching her tight virgin pussy. Their bodies are slick with sweat as they rut against each other, Michelle's juices coating her brother's cock, making their movements smoother and more urgent.
