Definitely a Gold Nugget - 20 minutes of non-ejaculatory multiple orgasms followed by 5 minutes of ejaculatory contractions even after there was no more seminal fluid - pumped dry!

Well here's an adventure worth noting!
Have been having solo MMO's for a
couple months. Only mild to moderate
intensity. I have, er, issues. Seem to
tighten up and disassociate when too
much pleasure calls. Oh well, it's pretty
enjoyable to investigate and work with it.

Today, on impulse, my wife started to
stimulate my penis manually just for fun.
As I got fairly excited I did KS a couple
times and had nice echoes but was
starting to approach PONR. I asked her
to switch to perineum. When she did and
I KS'd BIG echoes started. Increasing
rapidly to full on orgasmic waves. I think it
was the added excitement of having her
doing it plus the mysterious influence of
the Yin balance, at any rate, I had a very
intense non-ejac orgasm that lasted in
rising and falling waves for maybe 20
minutes. Mostly perineal stim with
occasional, brief, light penile contact.

At that point she switched to more intense
and constant penile work. Later she told
me that though she was enjoying
watching my obvious ecstasy, she had
more fun directly on my penis and she
was starting to get a bit bored. This type
of stim caused me to slowly shift over to
a more physical excitement combined
with the pre-existing energetic orgasm
that was continuing.

I passed the PONR and ejaculated with
some of the most intense pleasurable
sensations I have ever felt. The
contractions and waves of pleasure
continued long after my store of semen
was, um, all over the place and even
though there was no more to ejaculate, it
was as if my body was still trying. The
intensity finally gradually subsided. She
estimated that that final phase lasted at
least 5 minutes. Also I continued to have
occasional mild waves for an hour or two
after.

I've said it before, I'll say it again, "Jack,
thank you! You're a genius!"
