You little slut hit your balls hard 10 times.
To thank you for listening carefully to what I asked you to do, you will be able to jerk off, which is rare, I don't let all my submissives do that.
But I'm not crazy either, every 10 hand strikes you hit your balls hard 5 times.
I want you to do this 10 times, and you're lucky it's not me doing it because I wouldn't have held back.
