Machine Gun Orgasm

Okay… so I experienced something over the last couple of days which I have never experienced before… and which I also haven't really read about… so here goes.

I started with the Aneros back in late July, and had my first non-ejaculatory orgasm sometime in early December of last year… so it's been a little over a month since I achieved that. Basically, I achieved it using the Peridise, and in particular, the two middle sizes work the best for me so far.
I think the Peridise is my favorite product.

So, I decided to take a break for a couple of weeks. During this time, I had many non-ejaculatory orgasmic sessions without the Aneros. A couple of days ago, I decided to end my break, and I decided to use the Progasm Jr. Before I started with the Aneros, however, I had been having some Aneros-less dry orgasms and I had been doing that for maybe an hour or two that day, not directly before using the Aneros, but I took a few long breaks. So I had had the Progasm Jr. in for a while… maybe an hour, and I had a typical "climax" moment like I do many times, where there is the feeling of suspension, the spasms in my legs, my abdomen, etc. But then something very new and unexpected happened…

I would describe the rhythm of most orgasmic muscle contractions whether traditional or non-ejacultory as being a longer, slow, and very organized rhythm like this:
___ ____ ____ _____

Then you have your non-ejaculatory orgasms where one comes on top of the other, and they have a more erratic pattern like waves on a pond, from two or more separate rocks being thrown in.
__ . __. .__. _._ .__ __. . __ ._

These tend to be more erratic. This is just like an interference pattern with regards to wave propagation, for those of you who are physics nerds.

Then there is what I experienced that night, which I will, for obvious reasons, refer to as the "machine gun orgasm". It goes like this:
……………………………………….

It is a highly organized, insanely fast muscular contraction. Also, obviously, it feels insanely good. Interestingly, I was wondering if those muscles could move that fast, and I was very doubtful that it was possible since other orgasms which seemed to come on top of each other lacked such coherence.

When I experienced this for the first time, I thought it was just moving in time with my heart, and that my heart was really going just that fast, but I realized that it was actually going much faster than my heart. It kind of scared me at first, so I quit. A couple of days later, I tried it again with the Peridise, the second largest one. This time, it went even faster even than the first time, or so it seemed.

Since I had my first non-ejaculatories… I've been sort of unclear as to what constitutes a true Super-O as opposed to "lesser" non-ejaculatory orgasms, and I've seen some discussion about that on the forum here. Obviously there seems to be some kind of grey area. I assume that what I've been experiencing for the past few weeks has been a Super-O, but then there is this *new* level to it that I've just discovered.

Has anyone else experienced this machine gun orgasm that I'm describing? Is this a common phenomenon? Is this just a higher or more intense form of Super-O?

Just curious as to what you all might think.
