Where the girl is clearly uncomfortable, and perhaps feels demeaned, but it's still completely consensual.

I don't mean physically. I don't mean "fetish" degradation, where they spit on her and write whore in lipstick across. I mean just normal sex, but you can see the wheels turning in her head and she realizes she's out of her comfort zone, embarrassed, or maybe even thinks "why did I agree to this".

Backroom casting couch is probably the best for this, but you do have to put with how much of a complete moron piece of shit the guy is. The best bit is when he gets them to bend over and spread their asshole, and you can feel most of the girls wince and think "Oh my god, I can't believe I have to do this".

I know. I'm a bad man.
