Just before work.. it was cold outside and so nice and snug in my car. I didn't get any morning relief so I thought this was a good opportunity.
I started flicking through latex porn pics while I felt my cock growing. When it was nice and hard I started rubbing my balls and around the head squirming in pleasure. I ended up edging myself for about half an hour this way until I found a hot pic of a trans threesome and shot my hot cum.
I'll add pics next time.
