That was the exact scene that made me start this thread. The problem with it is she's a pro, not an amateur, and the crowd is staged. I'm looking for the real deal -- a real group of girlfriends, where the producer explains the dare, and you can see the girls checking the guy out until finally one of them goes for it, while the others look on in shock.
The shocked amateur crowd is a big part of the turn-on. I think it was the original Shane's World - College Invasion, where Taylor Rain is fucked in front of a crowd of real college girls and guys -- the reactions from the girls was so fucking awesome -- a mixture of being disgusted she was a whore, intimidated by her sexual skills and power over the male audience, and suppressed kinky arousal.
So, a crowd of real amateurs, watching one of their own try to take on a huge cock, would yield an even more interesting set of reactions.
An alternate scenario would be a College Invasion style coed party, where it is announced there will be a pair of pornstars fucking, and the guy is supposed to be hung and have a huge cumshot and the girl is supposed to have great tits and suck cock better than any other girl alive. The announcer will ask if any amateur couples in the audience want to fuck in public and can impress the audience more than the pros, with the crowd noise being the judge.
