I think it's time for a little pain, remember how I said I like a balanced session.
If you just edged when I commanded you to, then I want you to give your balls 10 slaps and then squeeze them hard for 20 seconds.
If you edged while doing the 250 strokes a few pages ago, then give me 20 slaps and squeeze for 40 seconds. For each additional edge, add the same penalty.
Since you're a self-described masturbation addiction, I don't think it is unreasonable to have some expectation of stamina on your part.
