Never had sex in the public, unfortunately. One time, I went out with a guy for dinner and I didn't really like him too much. I clearly told him, I didn't want sex. He said that's OK, and we stayed a little while at the restaurant and after that he asked if I wanted to go to the bar. I said, OK, for one drink. So we sat in this crowded bar, we didn't have too much to talk but I had a drink or two. We said beside each other, so he took his hand and moved it under my sweater, first moving it slowly up and down my back, then somehow he reached to my breasts, pulled them out of the bra, pinching them. I was going to tell him to stop but I just couldn't, I just loved it. Even though I didn't like the guy, I enjoyed it so much, being touched in that way in the middle of a big crowd. He then moved his hand back, under my skirt, into my panties, his large hands cupping my buttocks. I was pretty close to cum but he kept teasing me and pulling his hand out, he wanted me to beg for him not to stop. I ended up taking him home sleeping with him. Which turned out to be a mistake, but that is another story.
