Mistress Dula and her friend had tried to get some info from this guy but it did not seem to work. They did not have any more time to waste and they decided to dominate the guy in a way that he would not forget. That is why she chose to use sph to dominate him. She could tell he had a small one and so she used that to get the info.
This guy had a small dick and mistress Dula could tell. She knew he was the perfect person to make fun of as well as tease and deny. So she used her hot body to tease him and when he was turned on, she denied him on account of his small dick. It did not end at that as she humiliated him some more by making fun of his tiny cock.
Mistress Dula was not comfortable with the fact that this guy had a small dick. She had to make sure he did not try to hit on her again and to ensure that, she made fun of his small dick. He was humiliated and he did not want to face her again after that. The mistress even took photos and videos of it and of him. He never wanted to meet her again.
