Request Looking for *slightly* sadistic girls

Hello! I am looking for porn where the woman is amused by or gets some visible joy from a man's suffering. I don't want full on torture, but just some discomfort and the girl enjoying it. Like she gives him a handjob but the motion slaps the balls.

I sadly don't have a good example, but it is important to me that the girl is happy, cheery, maybe giggling - not sadistic in her tone. just a bit in her actions. thank you!
