Yes. I have. I had to provide some cum for a sperm count. I thought that all medical labs had a room in which the seman could have been "collected," but I was wrong. The seman had to be less than 10 minutes old. My choices were to rent a sleezy motel room near the lab, or "do it" in my car.
I didn't want to spring for the 40 or 50 bucks for the motel and I didn't want to J.O. in a parking lot near the lab. It suddenly occrued to me that there was a McDonald's just up the street.
It was lunchtime, and the place was crowed. It was winter. I hung my coat over the stall door to indicate someone was occuping the space. Then I lowered the baby changing table and put my "cum reciptlable container" on it. Like I said, the place was crowed. I could hear men talking, peeing, talking and bitcing. They were just a few feet from me.
I pulled my trousers and underware down. I have never had a proplem getting a hard on, so I started to J. O. I could hear all the men coming ino the restroom. I contiued to stroke my dick as I Ilistened to all the commotiton, just a few feet from me.
Within a few minutes, I shot my "speicum" into the conntainer they gave me and, I ran it over to the lab. But YES, iit was one of the most exciting jack offs I have ever had, just because there were so many people going about their business, while I was going about mine.
