Stepdaughter's secret masturbation caught by stepdad

A man came home from work early and found his stepdaughter sitting on the bed, playing with herself. He was surprised because he had never seen her do this before. He asked her what she was doing, but she told him that she was just playing with her toys. He didn't believe her, so he started watching her more closely. She continued to play with herself, and he couldn't help but get aroused by what he was seeing. He decided to join her and started touching her. She didn't mind, and soon they were both naked and engaged in sexual activity. It turned out that she had been secretly masturbating for a long time and had been waiting for an opportunity to do it with her stepdad. It was a wild and exciting experience for both of them, and they both enjoyed it very much.
