I will go into some details
I too was at the gangbang Friday. There were 4 guys but one stepped out "to the ATM" and never returned. So after waiting for a while, we went with three which was probably better.
It was great!! She was up for anything except anal digits. We tried DPP, DP and all the pornstar stuff except covered of course.
How often have you heard "Can we try two cocks in my pussy now?". Heh heh.
What I learned is that those porn guys must be pretty limber to do that stuff.
Even when you wanted to take a break to catch your breath, it was still fun to watch her sucking and fucking right there. You could be as busy as you wanted or relax and watch for a while. I grabbed a beer (BYOB) and enjoyed having a sip and bragging to my buddy on the cell as she was blowing me and getting it doggy from one of the other guys. I let her try to talk to my buddy but all she could do was gurgle.
And near the end looking for cum, it was great to have her say directly "would you like a blowjob, or fuck? Or handjob?" Quite the menu.
It was a great experience and I will repeat if she offers again.
