I was just chilling on the sofa listening to a nice track. I had on my “chastity cup” as usual and was greatly aroused. The erection subsided but about 20 minutes later, it came back, stronger than before. I began to meditate on the connection between arousal and sex. And when I did, some time later, I began to feel a quivering in my prostate and further-down in my anus Yes, it was an orgasm. A strong one. But not one, not two, not three. Rather it was an entire series of orgasms. Way beyond the “usual” MMO. By moving ever so slightly, or even breathing, I could “trigger” another one! And then another one! This was mind-bending! I felt like I have never felt before, even within an Aneros session! I don’t know how long I remained in this state….I feel like I could have prolonged it for as long as I wanted. Interestingly, at no time did I feel like I would ejaculate, even in spite of this extreme sexual arousal.

PS It is called “Extended Sexual Orgasm”. Here is some info. from Alan P. Brauer and Donna J. Brauer, who have written a book called “Extended Sexual Orgasm – How You and Your Lover Can Give Each Other Hours of Extended Sexual Orgasm”.
“For men, ESO is a state in which that moment of glorious sensation immediately before you ejaculate is extended – potentially for as long as you want – while your penis remains hard and erect and secretes copious amounts of clear pre-cum. The physical and emotional feelings that go along with this are like those of sustained orgasmic pleasure. To prevent you falling over the crest into a “normal” orgasm and ejaculation, you apply some simple techniques which allow your pleasure to continue to rise, plateau and rise again without you having an ejaculation. Remember that orgasm and ejaculation are separate processes – you can have an orgasm without ejaculating. That’s what happens during ESO. “

Without a doubt, this was the best experience of my entire Aneros “career” (except maybe for a few Super-O’s). This feeling easily “tops” anything I have experienced during a “normal”ejaculation! A caution: this is an extreme sexual arousal feeling and may result in an altered state of consciousness.
