Naked in a gynecological position, my patient is practically ready for the operation with his balls well tied by me previously; I have to manipulate them well to plan the surgery I am about to perform. I have to evaluate whether everything is ready, how full the balls are and while I touch and pull them I must say that I'm having a lot of fun: I like to mess with them and see him writhe in pain but also in pleasure as confirmed by his constant erection. I squeeze his balls and pull them hard, the patient no longer exists, for me now there are only these balls and I can't wait to start the surgery...
