I'm wondering what's sick about it. She's conscious, he's a big dude strong enough to hold her weight AND keep rhythm... I'm a bit impressed. Just because you don't like him because he told you that you weren't funny doesn't mean you need to go all PC Police on him.
*whispers* I don't know if you're aware of this, but this is a board about s-e-x. :O
What porn clip is it from? The girl looks very small and unable to defend herself if she had to. Unlike russ' example. One looks abusive/aggressive/forced on a very small paraplegic body and the other doesn't.
I can see why it would make someone wonder. But if the "actors" can be verified for age and willingness then ya its just more sex on a sex site.
