You are in hospital and in your adult baby clothes and wearing a cloth diaper with plastic pants that you have wet big time. What else could you do? You could not get to the bathroom on your own.
But lucky for you, sexy diaper lover nurse Kari has come in to change you. When she is wiping your pee pee she realises you and getting a stiffy and enjoying being touched.
Well, Kari adores cocks in diapers so she rubs her hand up and down, over and over until you get rock hard ready for her willing mouth to suck your rigid tool before putting a fresh diaper back on you.
