jerked off after seeing sexy woman while walking with my wife

My wife and I were walking downtown today after seeing a movie. It was in the 90's and women were wearing as little as they could (which is usually the reason I agree to go downtown with her...). We happen to stop at a bench across from an ice cream parlor and sat down for a few minutes. Just as we were about to get up and head back to the car, a fucking gorgeous dark skinned woman walked by wearing a skin tight full-length black lycra dress that was juuuust barely seethrough and hugging her in all the right places. But the way the sunlight hit her, as she was walking towards us, I could clearly see that she wasn't wearing a bra and her huge tits looked amazing. As she passed us, I couldn't help myself from looking at her ass. Again, the sunlight made it just a little seethrough. I got so hard it almost hurt. So, I suggested we get some ice cream. We walked in and I told my wife that I needed to use the restroom; told her what I wanted so she could order. Yeah, went in, locked the door and used the mental camera to rub one out. It was pretty quick. Thank you, whoever you were.
