This goes back to my college days. I was going with my girlfriend to see our football team play in a late season game. It was early November, cold, damp, windy and overcast. We had Bob Uecker seats at the top of the stadium so we took two sleeping bags to get into to keep us warm. We got to our seats and began to get settle. My girlfriend suggested we zip the two bags together so we can both get in. So we did and got settled to watch the game.
Well our team, as usual, was not doing well. As it drifted toward the 3rd quarter people started to leave. I was not very interested in the game and was about to suggest we leave when I felt my girlfriend hand sliding between my legs. It surprised me to no end since she is a very conservative person. Anyway, my cock popped right up. She ran her hand up and down it as I closed my eyes to enjoy the moment. She then found my zipper and soon my cock was in her hand. She looked at me with a smile and started to pump it. I was so afraid that someone would know what we were doing, though there was empty seats right around us because they had left early. But this also heightened the excitement. I could feel my precum beginning to flow out which she used to lube it. This went on about 10-15 minutes. I finally felt my load building. I indicated to her that I was close but she did not stop. Before I knew it, I was shooting my cum all over the inside of the sleeping bag. It was unbelievable. The hardest part was not to be overt with my reaction. Once my orgasm subsided I look around and no one seemed to have noticed. My girlfriend took a napkin that she brought along and wiped up her hand, myself and the bag.
The game continued well into the 4th quarter. It started raining lightly so we covered ourself with some plastic. The rain and the lopsided score sent a lot more people to the gate. However, I had one final score I wanted to make. I slid my hand between my girlfriend leg and started rubbing her. She started immediately moaning ever so quickly. I think she was wondering what took me so long. After a while I opened her pants and slid my hand down her panties to a very wet pussy. After a few minutes of this she stopped me. She was moving around a little then slid over to sit between my legs. Then I realized she had slid her pants and panties completely off. I then reached around and started to heavy play with her pussy and tits. I really began concentrating on her clit. I turned up the speed slowly. As I did this she ground her ass more and more into my crotch which now had expanded to its full length. I went faster and faster and so did her ass. Soon I felt her tightened up and start to cum. Her grinding kept going and this let loose another spasm of cum out of my cock.
Next thing we knew the game was over and there were very few people left in the stands. We quickly cleaned up, dressed and rolled up our sleeping bag. I can say that this was the most exciting football game I have ever cum to!
