The stepbrother and stepsister had always been curious about each other, despite their familial relationship. One day, while the stepbrother was in the bathroom, he heard a soft knock on the door. Thinking it was just their mother, he didn't hesitate to answer. Imagine his surprise when he saw his steamy, nubile stepsister standing there, eyes wide with excitement.
She didn't waste any time, pushing her way into the bathroom and locking the door behind her. Before he could say or do anything, she was standing right in front of him, breathing heavily. Without another word, she reached out and grabbed his now-erect cock through his towel.
Her touch sent shivers down his spine as she began stroking him, her eyes locked on his. He could feel the heat emanating from both of them as they stood there, inches apart. She took a deep breath before stepping closer, their bodies now touching.
