Yes, I've had something like that happen to me before. In fact, it was when I was taking some selfies outdoors and I posted one of those pics in my profile. I was standing in front of my storage shed (with the doors open) after a day of pressure washing a big rug outside. After taking the pics, I reached forward for my phone and I felt my cock (semi) pulsate once as a spurt of cum/precum shot out onto the cement. It was just that one shot.
This happens to me when I use a vibrator to stimulate my prostate. Loads of pre-cum and what feels like mini orgasms. Ive had at least four mini orgasms and then stroke to a full orgasm. Feels amazing, but I have to make sure I make time for this.
