There are a few stories that I have about my ex wife. I was only married to my first wife for about three years - college sweethearts and weren't meant for each other. The sex was great - probably because we didn't know what we were doing so we did a lot. The thing about her was that we wouldn't set out doing weird things but it ended to up there. I would start and she would come along - then eagerly join in.
Several times I masturbated her in public - movie theaters mostly.. The best time was going to back on the bus from the Jersey Shore to college at Fordham. The bus was kind of empty, the seats around us were not full. I started slowly, rubbing her through her jeans and watching for the reaction. She let me go, trying not to show emotion, but over a few minutes I would press hard on her mound and she would start to slightly open her legs. I moved to open the top button on her jeans - slowly as not to attract attention, and slipped my hand in. She spread little more and give me better access. I pulled the zipper down, looking if anyone was staring. There wasn't, so the zipper came down more and I exposed her pussy a bit. I rubbed her clit faster and she started to slightly breathe heavier. Just then, I looked in the bus window and you could see our reflection - and the reflection of a guy two seats behind who could see what we were doing. I started rubbing her harder and she started to come. She turned her head and had a great O face - which I saw in the window - and so did a guy in the car passing the her bus window who got a great view of her cumming. All of this before we hit NYC.
