How long has it been now since you've given up cumming for good? Six whole months? You're so advanced! By this point, you must be ready to graduate to the next stage.
Oh, you didn't think this was it, did you? No, this was just a stage. You've done very well so far, but the next stage is going to be much more challenging than anything before today.
So far you've been edging anytime you wanted. Basically, you've had free reign over your genitals, as long as you didn't cum. That stops today. Today, you get to make a very important choice.
You have to pick the path for your future development. Your options are: becoming an oral-only slut or an anal-only slut.
That sounds equal parts good and scary, doesn't it? You've probably already have a preference between the two, which is good, it means that you already know what kind of service you fantasize about. However, you shouldn't rush into it. Once you choose, the decision is set in stone. Take the time to really think about it, weigh the pros and cons of each alternative. Let's take a look at them together.
Becoming an oral-only slut
This is by far the more challenging of the two paths. Your mouth and throat don't have the pleasure centers that your genitals or ass have. This means it will be very difficult for you to reach the edge ever again. It won't be impossible, because arousal is a function of the brain, and with a lot of work, it is possible to rewire your brain to get the same kind of arousal out of sucking, licking and gagging that you get from edging your genitals.
However, it is the more rewarding of the two as well.
First of all, by choosing to be oral-only you are making a statement that your pleasure does not matter to you as much as the pleasure of your partners. You are saying that you accept and crave a life of servitude and obedience. You are saying that your goal is to be the best toy you can possibly be, choosing to disregard your own sexual gratification as irrelevant.
Second, choosing oral-only service means that you will never risk accidentally cumming. You will be facilitating the denial you started all those months ago. No chance of an accidental orgasm, no chance to be relieved from the needy state you have chosen to spend your life in. Your mind will continue to grow fuzzier and fuzzier with arousal, while your genitals stay unused and untouched, reduced to being just a reminder of what a needy, submissive little slut you are.
Third, your quest to be able to reach the edge again will make you explore ways to rewire your brain to associate your mouth, tongue and throat being used with physical pleasure. This will mean you will ultimately be drawn to hypnosis, making yourself more obedient, more submissive, more willing to explore new fetishes in the process. You'll start craving that nice fuzzy feeling you get when in trance, which feels a bit like how your mind first felt when you started denying yourself, but much stronger. Ultimately, you may wind up overwriting your whole personality with that of a perverted little mouthslut.
Becoming an anal-only slut
The main advantage for choosing anal-only service is that anal play is a lot more pleasurable physically than oral service. That means that it will be easier for you to retrain your body and edge using your ass instead of your genitals.
A second advantage is that for any cocks you may be servicing, your ass will feel much better than any other way you could possibly service them.
A disadvantage is that you can't really use your asshole to service a pussy, so that is something that you'd be giving up by choosing this path.
Furthermore, the fact that anal play can bring you to the edge easily means that it is possible to have an anal orgasm, ruining your denial streak. This risk will be especially high when you get started and don't yet know your limits.
Being anal-only will make you into a needy little slut as well, and the position of your asshole means that when your partners fuck it or tease it with cocks, toys, hands or mouth, they will be very close to your genitals. They will, however, never touch them. Knowing this, feeling this every time your ass is being used will prove to be more frustrating than you can anticipate now. This is both an advantage and a disadvantage, as you no doubt already know.
This is not a complete summary of the advantages and disadvantages of becoming oral-only or anal-only, but it will help you start thinking more seriously about it. Take the rest of the day to ruminate and then make your choice. I wonder what path you'll take.
