I had joked one day to my girlfriend that we should join the MHC on our upcoming vacation to Europe. She had never heard of it! Once I started telling her about it, she was really interested. For the weeks before the trip, it was a frequent topic. As we were getting on the plane, she would occasionally brush by my penis. After dinner, and once the movie began, the lights on the plane were turned down. It was a crowded flight on a new A330 and we were in a window row to ourselves. I reached under our blanket and started rubbing her crotch. She just looked at me with a smile, then unzipped my fly. She started squeezing me and soon I had a rock hard erection. She pulled her pants partly down under the blanket. I wasn’t sure but I think this guy across the aisle and slightly behind us was watching us. She turned away from me and moved her ass to my hips. I started rubbing my penis against her clitoris. She reached back and put me in her. We moved slowly and went at it for at least half the movie. I had to cover her mouth while she had several orgasms (she is usually quit vociferous!). I finally came and we sort of just remained there in the same position. I eventually softened and pulled out. She didn’t pull up her pants till we almost landed. Several weeks later she gave me a scrolled up piece of paper. I opened it . . . and it said, “This is to certify that (me) is now an official member of the Mile High Club” She had made a certificate with her flight ticket stub pasted right on it. I want to frame it and put it up at work!
