I'm guilty of this on more than one occasion but my best public hot tun orgasms came when I fucked my volleyball coach in the hotel hot tub while we were traveling for a tournament. That was a great time!

I think both are fun and like to do both. I like the taste of cum so enjoy having it in my mouth, so I frequently like the guy to fuck my pussy or ass and pull out and shoot in my mouth. If he wants to cum on my face, that's cool too. If he wants to cum in my pussy or ass I like that as well, just not as much.
