Crouch position with your leg wide open. Masturbate infront of your mistress and beg her to observe your pathetic face. You’re not allowed to cum unless your Mistress allowed you to do so.
With the permission of your Mistress, masturbate with one hand and spank your ass hard with the other hand.
Remember to count each of your own spank in the order of ” 1, thank you Mistress ” ” 2, thank you Mistress ” and so on.
