When I was 18 and still a freshman in college, I let a group of eight much older men pay me a lot of money to be the center of their circle jerk.
It was actually kind of fun, we hung out for a bit, had a couple of drinks then they had me get naked and lay on a covered futon mat. There was a no touching rule so I just laid there and played with my titties and pussy like they asked while they all stood over me and jerked off. It took a little while but once one guy started to cum they all went soon after and I got covered from top to bottom!

I must admit I enjoyed it. Something about making eight guys cum for me and not even touch one of them is really hot to me. But, I bet they loved cumming all over my eighteen year old body more though..lol
