Last night I [F] blew a stranger [M] in a bar bathroom while my bf [M] got me a drink

Last night I [F25] I blew a stranger in the bar bathroom while my bf [M24] was getting me a drink.

To start off, my SO and I have discussed threesomes and having sexual experiences with others. We are both very adventerous when it comes to sex which is what has led us to start posting on reddit.
He has told me , more than once, that he thinks the idea of me hooking up with a random guy is really fucking hot and to be honest the idea really turned me on too. But it was always talk and we never really made any real steps to make this happen… until last night.

We were travling for the weekend, in a new state, staying at an airbnb. Our last night out, my SO and I were both very horny, we barely even left for the bars because we just wanted to fuck eachothers brains out. Eventually we called the Uber, both of us were already buzzed as we were pregaming the night with some good wine.
I had on my short black dress that fits really tight on my body. At the request of my bf I was not allowed to wear any bra or panties. Which was just fine with me because I love to flash him whenever I get a chance inside or while we are between bars.
