it took me 4 years, but i made it

First a little back story. I bought an Aneros before there was an MGX or SGX which was about 4 years ago. Whenever it was that they updated their product line to include, the Helix, I bought one immediately, since I never had the feelings that I felt I was promised. Again, whenever the Progasm was released, I bought that within a few weeks. I've been using it about once every week or so, whenever I had time to myself in the house.
Finally last week, while I was home from work I had what I think everyone has been referring to as the Super-O. It took me a long, long time to reach the promised land, and I think it was due to marijuana. I hadn't smoked in years, and had swore the stuff off, but had one of those ah-ha moments where I remembered something that had happened to me that I thought might be a connection.
About 8 years ago, I had smoked too much pot, and put myself down to sleep, because I could no longer keep my act together. I wanted to masturbate, but didn't have any porno around to get aroused, so I tried to imagine what it would feel like if I mentally tried to send signals down there to pump in up. I tried to imagine a brain wave traveling from my brain down my spine, up into my prostate/penis. It worked, and before I knew it, I had a rock hard erection. I kept going with it, and started contractions in my sphincter, thinking about a rumor I'd heard that yogis could bring themselves to ejaculate without touching themselves. It got to a point where it felt amazing, but I eventually had to masturbate to finish myself off.
I'd always thought about that experience whenever I used the Aneros, and I've always tried to recreate that experience. But by the time I'd purchased an Aneros, I'd quit smoking pot. This past Monday, I was home from work, and smoked some pot, because I had it laying around the house after a party. I thought it would be a nice way to re-introduce it, by trying it by myself, and not stressing out or getting paranoid around strangers. Something in the back of my head told me to try the aneros at the same time, and that maybe that connection I'd always imagined might be a real connection.
I had what I would consider a usual session and after about 45 minutes I got up, smoked a big bong-full of pot, and laid back down. About 10 minutes afterwards, I imagined those brain waves again. It started working really great, and had the Aneros moving around much more than usual. I tried to think about it moving, while not actually forcing any movements. My dick was bouncing around a bit, so I put on a g-string/pouch type of thing I'd bought as a joke years ago, simply to hold my erection in place.
I'd previously gotten to a point where I had some hip gyrations and hip thrusts, and this time was no different. I had previously thought I shouldn't move around too much - that it was the Aneros that should be moving, and not my hips. This time, I decided to go with it. I started thrusting my hips, and it started feeling out of control. It was as if someone else was making me fuck an invisible woman who was on top of me. I got a cramp or two, but after about three tries, I finally had a rhythm going, and even thought my dick was being held in place by this g-string I felt like my dick was really going in and out of a super hot and wet pussy. I had a laptop on my chest this entire time, and I was checking out some porn, but my thrusting was getting way too intense, so I had to set it down. Once I'd cleared myself of distractions, I finally let go, and felt like I was an animal fucking the hottest piece of ass I'd ever seen.
It felt like I was humping this invisible babe for several minutes, and finally it happened. It felt like I was shooting thick, powerful ropes of cum 10 feet in the air. It lasted for about a full minute. I looked down, and the g-string, that was made of a satin material, was leaking cum. I'd never touched my penis, and I came a tremendous amount!
I've yet to even attempt it again, but I will. Has anyone else had an experience like this? Is a Super-O actually cumming, or is it simply everything leading up to it? I have a million questions, but I'd like to hear what people think of this experience before I try again.
