Goddess Gabriella wanted to make sure that this guy stopped being insensitive. It was triggering her and it was something she did not want this guy to do. So she had no choice but to make the guy endure the pain of being facesat on with her jeans. The mistress not only facesat the guy, but she also trampled and stomped on his stomach with her feet. He was lucky she used her bare feet.
Goddess Gabriella wanted to inflict a lot of pain on this guy and she did it with her jeans. She knew that if she facesat him with her jeans, he would not have a choice but to do what she wanted. That is why the mistress did not care about him and what he felt. She only let him go when he peed his pants as he struggled to break free.
