OP, when you go in for the close up, whip it out. She'll be surprised, but she won't want to waste the sex tape so she'll just play along. Trust me. Trust us.
Play it straight OP, direct it in a serious manner, and make sure when it comes time for the money shot we don't get the overdone "hairy armed man jerking off on female's face" mix it up a little bit.
Since the question is "would we do it" and not "should OP do it" it would really depend on the friend asking and their partner. I don't have any moral qualms against it but I'd really hate to witness some bad sex and have to pretend it wasn't. I also wouldn't want to make any eye contact with my friend, especially since I'm not sexually attracted to any of my good friends. It would just be awkward.
I'd be more likely to say yes to good acquaintances whom I don't see very often. Who also happen to be hot. That would really help.
It's a gesture of friendship because I'm a natural tipper with all types of service. Sometimes she insists that I don't tip or most of the time I will get free dances on the house. So you go to a restaurant, your buddy is your waiter, and you don't leave him/her a tip because 'friendship'? You sound like a mean friend!
Yeah, I tip generously but whenever it's a friend working I tip even better. I'd imagine if my friend were a stripper and I still got lap dances and I'd get one from her I'd give a better tip too.
Answer to the question in the OP:
It really, really depends. I don't have any friends that I'd do this for at the moment; but in the right state of mind and with the right friend/couple I might. Not to get involved in the action, but to have that experience I guess.
There's a good chance you can get laid. I don't know you and the girl well enough tell you exactly how to play it, but I'd play it straight. Try not to be creepy camera guy. Play it cool, and she'll invite you if she feels like it.
