Best ride to date!!!-gctid155350

I have been riding for a few years now. It has been a very slow progressing journey for me. I have had some nice consistent feelings mostly, some really nice mini o's, and a super o. I just wanted to share and maybe get some thought s or comments on my ride the other night that I had. I had got home from work and decided to take a ride. I had to mow the lawn so i thought hey I will slip this thing in and mow the lawn. When I'm done I should be relaxed and used to it. So I lubed up slipped in my helix syn and mowed the lawn. Nothing happened but grass getting cut. I usually ride naked so of course I got naked laid down put some porn on the TV and turned up some music. I'm laying there getting some really nice feelings goings. Waves coming and going. All of a sudden the helix decided to do a little grass cutting on it's own. This thing took off and started bouncing around in me. The gentle feeling of it sliding in and out. Raising my arousal with each movement. I wanted to grab my cock so bad but I held off. Had some really nice contractions that had me in a u shape. I was laying on my back knees bent. After about 45 mins I was kinda at a flat spot. Couldn't get the feelings any stronger so I decided I will slip in my progasm. Had also got another thought about putting on a pair of underwear that I got for a laugh but ended up actually thinking they where very comfy and my girfriend loves when I wear them around the house. They are elephant trunk underwear. See pic. So I skip things in and on. And right away I feel the tightness against my prostate and it feels great. Riding for about 10 or 15 minutes and this thing took off. Pressing and releasing. I felt my thighs start quivering, my asshole start puckering in and out. Auto pilot was fully engaged and this flight was airborne. My ass getting pounding and asking for every bit of it. It just wanted to swallow the progasm up. I'm in a full body contraction again bent up in the shape of a u. I could not let it go. My body was stuck. I was trying to do the do nothing approach but with every sensation hitting me, my muscles going crazy it's hard to just lay there and let it be But I managed thru it. All of a sudden I felt my balls tighten a warm rush from chest down to my stomach and into my cock. My cock was dancing on its own to the beat of the music. Up and down tightening and loosening. I got another warm wave over me. This time it it came to the base of my cock and very slowly rose up to the head with a feeling like I was being jerked off. No hands here. No one or thing was touching my cock other than the underwear. I shot out the biggest load of cum I ever seen. Not one spurt, not 2, not 3. It was a long stream of cum rising up about 2 or 3 inches out of my cock. It lasted for like 15 to 20 second. It felt like spurts but I think that was the progasm sliding past my prostate each time giving it more energy and making it more intense. At last my body let go of the contraction and I was able to relax with this huge pile of cum covering my cock,balls,my stomach and my inner thighs. Wow. I tried to ride longer but I was spent.
Not sure if this was the underwear that helped or just a good ride. I will try it with them on again to see. Thanks for reading.
