Mistress Valentina needed to have fun at the expense of this guy. She teased him with her gorgeous tattooed body. He loved what he saw and he planned to do some crazy and naughty things to her. She got him to wear her chastity device and that is when everything changed. She now had him by the balls and she had fun dominating him and getting him to do whatever she wanted.
This guy was getting too comfortable with mistress Valentina and she did not like that. She felt that he needed a wake up call and so she went out of her way to trample and scare the loser as painfully as she was able to. She used her chastity fetish to deal with him and he cried as she did her thing on him. He regretted getting too comfortable with her.
