Wearing a Vibrating Device in the Gym

I have several pair of compression (spandex/Lycra) shorts I wear under my pants to the gym to keep things in place while I workout or do cardio.  They have a pouch in the front, I assume for an athelic supporter that I've not used but it got me thinking... I bought a toy to test out on my woman and it was a smashing success, its an odd shape and wasn't really useable as a cock ring for couples but when I sandwiched her clit between the two prong ends she came repeatedly several times until she made me take it off, got too sensitive.  If you are in the market, its a pretty damn effective vibrator.   I was feeling a bit left out, but while getting ready to go to the gym, I decided I could smuggle that little toy in the front pouch of my compression shorts and see how it felt to get buzzed in public, in front of random strangers in the gym.  This one comes with a small remote control that will cycle through its various vibration patterns and a middle "pause" button if things are getting too serious.   I wore it to the gym on cardio only day, figured it would be too distracting for weight training.  Once I started stretching, I reached in my pocket and hit the pause button and it buzzed right to life.  The way it was configured in the pouch, the solid part was on the bottom, resting on my sack between my balls and the little finger ends were going straight up, but my cock was flaccid and  laying over to the right.  The buzzing was pleasent and sure enough, I started getting hard so I had to surreptitiously adjust my cock so it was straight up, between the prongs.  The prongs vibrate much more than the solid base so I had to pause the thing pretty quick so I wouldn't cum.  I started cycling through all the pulse patterns until I found one that was almost sync'd to a resting hear rate, just enough to keep my hard but not enough to push me over the edge.   I found an open treadmill and started an incline walk at a slow pace so I could focus on the toy and finding various vibration patterns.  Within short order, a young woman with a very nice figure positioned herself not far in front of my treadmill and started working stiff-leg dead lifts, in some really form fitting yoga pants.  They were light grey and I swear I could just make out her labia from behind when she would bend over.  I tried my best to not be completely obvious with my gaze, adjusted the buzzing frequency to a nice steady buzz and let my imagination run wild.  Within a minute I reached the point of no return and had to slow the treadmill to a slow crawl and hang on to the handles as my cock erupted inside my compression shorts.  I felt the warmth instantly spread around my waist, just below my belly button and start trickling down either side of my cock and pool around my balls.  I'm sure my walking got all unsteady, as if I was having a stroke or drank too much.  It was a complete thrill to know I just jizzed my pants in public, walking on a treadmill, staring at a beautiful girl bending over and flaunting her wonderfully developed peach.   Of course, I had to drive home in my sticky mess which wasn't the best feeling and when I got undressed I was amazed at how strongly and pungent the semen smell was.  It smelled exactly like the powdered amino acid L-Arginine which I take as a pre-work Vasodilator.
