Catheterization is a lovely pastime, I have complete control, As soon as the tube hits the bladder you have the urge to pee, except I have clamped the tube off with forceps. Now I can massage your stomach to make the pain even worse. I give you some little pleasure by un clamping the catheter for a second. The vision of joy on your face is short lived though as I clamp it on again. This will continue until I decide that I have had my fun, then I will allow you to empty your bladder into my sample bag.
