What is it with guys sticking their hand in the girl's mouth in porn?
 

discuss...

you mean the fish hook?

I'm more into the porn where the guy sticks his fingers up the girls nose. Snot is so hot, thats why it rhymes.

Degradation I believe.

Checking their tonsils:1orglaugh

They like to serve good buffet lunches on porn shoots, like BBQ ribs, chicken, egg rolls - so it is just reminding the starlets of a really good meal waiting at the end of the scene.

i don't know what it's called

Well, I think it's because when a guy is fucking a girl he can't get a blowjob at the same time, so to include some oral action, they use fingers...it's a real turn-off imho, especially when the guy has some ugly fat thumb with long fingernails :ak47:

They saw some other guys doing it and thought that's what sells... :Graucho

To check how far it goes, to, later on, fuck her throat...
