I Can Have an Orgasm, Part 2

I was sitting on the back seat between Barbara and Annie, wondering what was going to happen next. Then I was shocked to here Annie say to me, you are going to show your penis, and Barbara is going to show her vagina, and I am going to show you how they are the same. That's crazy, I said, they are entirely different. No, she replied, it's a scientific fact - I saw it in a book -- now, let's see. I looked over at Barbara, and she wasn't doing anything, but I thought why not, and I unzipped my pants and started to pull my fairly erect penis out through my underwear. Then, Barbara pulled up her skirt and began to pull down her panties, all the while looking over at my erect penis. She seemed surprised by what she was seeing, and she asked why it was so big - it isn't that big all of the time. No, Annie said, it's big because we are 'doing sex'. Anyway, I said, it's obvious that my penis and Barbara's vagina are not at all the same.
