Nurse CBT

You have an appointment today. As soon as you walk in I instruct you to close the door and remove your pants. In order to see your full potential, I must tie a string around your cock and balls. I make it super tight and your dick is instantly harder. You keep moaning loudly so I shush you and cover your mouth a few times. My voice becomes softer and I whisper to you. I keep stroking your cock and once I put lube on it, it becomes more difficult for you to hold in your moans. Finally I let you cum in my hand. I expect to see you next week
