Lock

With your thump hold middle and little finger of your left hand. Then with the others , index and ring-finger,grab your cock and the head must point up between them. With the right hand make the shape of reverse U and hold the two extended fingers of the left hand. You just put a lock on your cock. Now you can start masturbation without lubricant ,cause the presemen liquid works well. The shape of reverse U you can make it with any combination of fingers like thump and index ,thump and middle finger which I recommend to the fellows masturbators ,cause the head of my cock touch my palm. Keep on masturbating.
