You play her game.

"Okay," you say, "what do I need to do to earn clothespins?"

“Oh you make me so happy. Come here and give me a kiss.” You kneel up and lean towards her. You kiss for a few minutes, tongues intertwining. It is a very enjoyable kiss.

“You have earned your first clothespin for choosing to play with me. Stand up.” You stand up and wince as she places a clothespin on the head of your cock and flicks it. This is going to be harder than you think. You have only one clothespin on your cock and hurts. “You are so hot. Look at you. You are standing in the street completely naked with a clothespin on your cock. Oh good god I am so wet. Are you ready for your first task?” You nod. “Good she says,” as she twists the clothespin. “Here is your first task.”
