First super O, first dry orgasm then the 3e with ejaculation

Hi guys,
im an newbie to this forum,,, 31 years, from holland old and trying to get a super-o for e few years now,,
the last couple of weeks i again did some serious tries but had no real succes,,,
Today i gave it another go,, i grabbed a smaller aneros and expected nothing really,, but when i put it in i inmidiatly feld my prostate pulsing,,
within 5 minuts of relaxing i started contractions,, first soft ones that i bit harder,,
Then i started a mild to strong contraction for as long as i could hold it,, then i hade my first small super o,,, My body started shaking al over,, amazing feeling,,, then 5 minutes later the 2e one came,,, even more intens,, it was like i train i hade to get on,,
But then after another five minutes i hade the 3e one,,, but it was mind blowing,, i was shaking so bad that i couldn't control myself anymore,, it was like i was on drugs or something,,, nothing like 2 two others,, but after i stopped my stomach was full of sperm,,,

What just happend,,, ? Any ideas
Thanks !
Grtz
