This is my first story, and by the way this really did happen
A couple of days ago, the marching band that I'm in, marched in a parade two or so hours away. We took a couple of charter buses with probably 50-60 on each. I sat with my girlfriend and we talked and was playfully toying with each other, turning each other on slowly.
We arrived there, and marched and by now it's dark outside. We got back on the bus and she took her sweatshirt off (she had a t-shirt on under it) and tossed it casually on my lap. I went to move it and she told me to keep it there. We left for home and she reached under the sweatshirt and was pushing and prodding my dick getting me hard. (this was the first time that she had done this) She was grabbing my dick through my pants and she slipped her hand up and undid my zipper, my dick popped out because by now I'm very turned on. She then pumped and was playing with my dick until I told her I was going to cum. She put her other hand on top of it and I let go. It was one of the best orgasms of my life! after that she licked all of the cum out of her hand and we made out until we got home.
