Introduction
 I decided to have a ‘quick’ session with the Helix Trident.  I had not ridden it in a while.  I am only in Day 3 of SR so my expectations were not too high.  As soon as I started, I began to feel the nice P-waves and an almost immediate erection.  I was wearing my SafeTGard “chastity cup” with the XO ProCup (instead of the Cage Cup).  I did not feel any Dry-Os this time around but that was okay.  I still expelled some prostate fluid (not precum because it was not slippery and sticky).  The Helix Trident (due to the combination of P-tab and K-tab) allows for a nice, easy and quick “in-out” motion caused by the two tabs.  It doesn’t take too much anal or PC contractions (kegels) to get the flow going.
An “Experiment” In Male Chastity
 I don’t know what prompted this but as soon as this session was over, I decided to replace the “chastity cup” (which I wore during the session)  with a traditional jockstrap (athletic supporter)  for the rest of the night and see what develops. I didn’t want to ejaculate so in my mind, this substitution was okay.   I couldn’t predict the outcome.   I selected a Bike swim/run jock (which is not too restrictive and has a nice soft knit pouch), put it on under my PJs and went back to bed.

 An hour or two later, I awoke with a NPT (night-time erection) that belied my Day 3 SR condition.  I could not believe the stimulation now acting on my penis and especially the frenulum.  Saying that I felt close to the PONR was a gross understatement.  What I felt was a combination of a near-wet dream feeling and literally being in a (female) penetrative state of sex. Literally!  In other words, f*****g awesome!    No exaggeration here;   I was completely paralyzed in the feeling of sexual intercourse and  felt that with only a few more “strokes” I would be ejaculating!  But it’s only Day 3!   So much for this “altered” male chastity state!
