I don't find a woman with a shaved head attractive. But I'd be an interesting visual to see the victim's saliva/snot/vomit leak, unobstructed, to the top of the victim's upside down skull.

You know, you're absolutely right.

You'd have to shave their heads (preferably without their consent) while shooting the scene. Otherwise, the only whore who'd show up with a shaved head would be Belladonna, and let's face it, that would only be degrading to the stunt cock.

Can Belladonna be face fucked with her teeth clenched? I mean through the gap in her teeth.

Yes, but it would be called "Gap Factor".

Belladonna's not doing anymore Gag Factor shoots any time soon unless JM is prepared to meet her demands and give her a stake in the company (not likely), since these days she's high stepping it with partner status at EA.
