From handsfree to aless in one hour

During last several months I'm trying to achieve handsfree ejaculation. Reading, relaxing, watching porn...Yesterday I was lying naked in bed for afternoon nap. Slept for 30 minutes and woke up from noise. I was still fully relaxed when decided to give a try. Watched some porn on my laptop, breathing and 15 minutes later got an erection. Tried to focused on penis head, visualizing tongue licking and female mouth sucking me. I got some precum, contractions and vibes on my cock. Lost erection, but contractions continued. Then again semi erect I had the ejaculation feeling but no cum. Maybe 30 minutes later I could feel that all feeling is going to my prostate. Lost erection but pulsing started inside me. Oh my god...It hit me at once. I lost control, my eyes were closed and started seeing some color circles. My head was pulsating, so was part of my lower belly and perineum.
I was flying. I got full body orgasm, 30 seconds, then back on earth but just for a while, then again aless for a minute or two and this one for about an hour. At the end I realized that this was the biggest orgasm I ever had so far.
Most interesting part was moving sensation from my cock to my glant even my mind was busy trying to achieve ejaculation. I will try again, to see if result will be the same next time.
