Slutföra en beställning att slå mina bollar 150 gånger med en gummiklubba

I am chatting regular with a nice girl (18+) who likes to order me to hurt my balls. She does not not ask for any money like most of the Mistresses. Therefore, I always complete all tasks of her. Same for the one when she asked me to hit my balls 150 times a rubber mallet.
