I think she is a bit too rough with him. It would be much better if she teased him slowly as this is actually more tormenting than just tugging his cock the way she is doing. Also she paid no attention to his balls. She should have tickled and teased them a bit. Poor guy also said not to do it after he cums which to me is a boundary she crossed without his consent. I can see it was fun for her as she is evil but If i was her i would have given him a break after he cums and then go back to him for more lighter teasing.
