Masturbating with Bladder Full

I discovered how pleasurable in a really novel way it could be to have an overly full bladder one time when I decided to rush and not take a bathroom break after a day-long conference so I could get on the road right away for my 2 hour drive home. So, what I didn't recognize right then was that I already had to pee, not badly but still. And since the last time I went to the bathroom I had drunk 2 cups of coffee, two cans of diet Coke, and a bottle of water. It wasn't long before I had to pee badly and was stuck in traffic. Still I persisted on my way and soon was wiggling my leg in bladder agony. However, this was different, too. I had felt all pent up sexually because it had been days since I had cum. My body felt full from the time I got up in the morning with an erection from some pretty sweet dreams. But because I had to drive to the conference, I had no time to masturbate before the work day. While I was agonizing over my bladder in the car stuck in traffic, my cock got hard. Really hard. I figured this could help because I thought, at the time, you can't piss yourself while you are that hard. When I got home I hurried into the house as fast as I could and had to pull my pants and shorts down to my ankles because I was so hard. I leaned over, way over, looking like I was a drunk or something because I had to try and point my hard cock down to the toilet. But no urine would come out and instead the tip of my cock was getting wet with precum. What to do? I figured I might need to cum first and then pee, but how? I figured that if I got naked, got in the shower and tried masturbating, no matter what came out I could wash myself off. This could get messy, no doubt. So, naked and hard and aching in two different ways, I got in the shower and sprayed the Neutrogena body oil my wife has in there on my penis and balls. I started stroking and oh my, what a great new deep sensation that was. My bladder ache turned into a sublime pleasurable feeling and so did the tension in my prostate. I didn't know what would happen first until I felt a flow start. I stopped my strokes to see what would happen. First, a short stream oozed, flowing out about 2 inches from the meatus of my cock, and I recognized that is prostate fluid, no contractions but was thick and clear and without sperm in it. Then that stopped as I felt something inside, deep, like a switch being turned. Next the pee squirted out and was so stimulating that my muscles inside clamped like an orgasmic contraction. And so what I call the pee-gasm started and I had some free flows of urine and some with contractions. My penis was still hard so I started my stroking more firmly and fast. A few short pee bursts and then, that clamped down and I felt that lovely orgasm burn inside and my cum began ejaculating. It wasn't as far as usual but seemed to be a lot. Lovely feelings, then my penis started to soften and I peed fully. I felt pretty weird that time standing in pee, and cum, in the shower, shriveling oily cock in hand. But, I was very relieved. I've now tried it a number of times and enjoy it when I can manage the time and arrangement necessary to be full like that and free to have the shower without interruption.
