Is it more Insulting if she Feigns Enjoyment really badly?

[tyler]

Just curious if any guys out there have ever had a foot experience where the female obviously faked her enjoyment REALLY badly.

The thing I'm most curious about is if you felt more insulted by the fact that she tried to pull one over on you big time or if you think it would've been more insulting if she just didn't showcase the loving display of emotions at all.

Has anyone out there ever had an experience along these lines?

Here's a visual aid (where a guy gets duped) in case anyone is wondering what I am talking about. It gets really bad toward the end and you can kind of see the sexual interruption in his face at one point (cuz he has to look at her briefly to assess if she's for real or not) that maybe he has been living a lie the whole time, LOL:
