By this point, it's becoming pretty clear you want to get as dumb as you possibly can. Well, good news, dummy! You're on the right track.
You've already started edging regularly and cumming less often. That's good. Keep doing that. In fact, do more of it. Edge more than you currently are and try not to cum at all. Your main objective by this point should be to be constantly edging and to never cum again.
You've already begun to hypnotize yourself with texts, images, gifs and videos. That's good too. Keep going down that path. When you're not edging, watch hypno videos or stare at one of the many spirals you can find on here.
Go a step further. Message your favorite hypno creator and ask them to hypnotize you. Ask them to give you instructions on how to edge and be sure to mention you don't want to cum. Ask them to imprint whatever triggers they like in your dumb head. Let them know what a dumb, horny, denied edgeslut you are and how much dumber, hornier and more denied you want to become.
You've already started drooling all over yourself when you edge. Do it more. Take a loose button and suck on it while you edge in order to stimulate more saliva production. Make sure to push all of that messy drool out of your mouth with your tongue from time to time. No swallowing!
Pick a mantra from the list below and repeat it to yourself constantly as you edge:
Once you have done this daily for a few months, you'll get to be really dumb. That's when you're going to stop edging like you are now. You will no longer use your hands to edge. You will only be allowed to hump pillows and furniture. All the other rules will still apply, making sure you keep drooling over yourself, you keep getting dumber, you keep getting more hypnotized. It's just that you'll be doing it while humping. This will be especially effective if you hump the pillow you sleep on, so when you try to sleep at night you can smell all the juices you leaked on it during the day.
That's it! That's all you need to do to get to be the dumbest possible, horniest possible, messiest possible, neediest possible edgeslut.
