Here is what you will do for me.
You can jerk off how fast and how often as you like. Now doesn't that sound nice?
I know, that's way too good for you, loser.
However, it will come at a price.
After every 20 strokes you do, you will LET GO of your fucking cock.
Then, you will squeeze the head of your cock with one hand until it hurts, and with the other hand, give yourself 2 smacks to the balls, and you better make them hard. Your pathetic little balls should be able to take two little slaps, right?
I know it will hurt so badly, but you can always jerk off some more and take away the pain, IF, and only IF, you are willing to hurt yourself all over again.
You will love this game, I'm sure.
When you think you are getting close to orgasm, let go of your cock, give your balls five slaps, that's right, FIVE SLAPS. I will be watching you.
Now fucking do it.
