Stroke that cock of yours 100 times. I know that some of you out there cheat on your strokes and stroke down for 1 stroke and up for another, but one stroke in front of me counts both the up and down parts, so don't try to cheat.
If you have to stop during this section smack your balls 25 times each with a wooden ruler. And don't even think about slapping them softly. I want those strikes as hard as you can. I want to see tears in your eyes, and red marks on your balls before you are done. Don't forget to finish your stroking session after you strike your balls.
