One night I promise to treat you to a night of erotic pleasure such as you've never had before. The only catch is, I say that you must obey my every word. We get in the car and I take you to a downtown skyscraper office complex. I bring you to an empty doctor's waiting room and tell you to wait and that you will be told what to do then I leave. You sit nervously in the waiting room.

The doctor enters after a moment and looks down at your erotic naked body. You are so hot; you can't help your hips moving a little bit in anticipated pleasure. The doctor moves to a drawer and takes out two strange looking devices that look like large paper clips. "My job is to prepare you for erotic pleasure.", says the doctor.

He squeezes each breast carefully and then squeezes the nipples. "I want you to tell me which gives you more pleasure, pulling on your nipples gently like this or pulling on them very hard like this."           

"Very hard", you say. The doctor lets go of your nipples and without saying anything else leaves the room.

"You'll enjoy this, I think".
