You'll use both hands in this method to create a sense of a continually rising stroke. Start one hand at the base of the penis and lift it to the top and off. While you're doing this, as soon as there's room start the other hand at the base and follow the first hand. Continue alternating in this fashion, and you should create the sensation of one infinitely long gentle pull. If you do this in reverse you get the Infinitely Going Down stroke.
