Hand + Floor

Take your hand, lube it up with your favorite stuff. This method works better if you have a place to stretch out. Take the hand with the lube, and make sort of an 'O' with all of your fingers. Lie on your stomach, or side, whichever is more confortable for you. Take your hand and place it on the floor with the 'O' facing up. Take your cock and place in the 'O' and slowly pump back and forth. If you can master this technique, it can be one of the best.
