Have you ever wondered, how does it feel to go extra hard on a deepthroat blowjob? That is almost what face fucking is about. You practically use her face like a pussy and just fuck it till she either drops unconscious or she has been vomiting all over your cock. If she is a good girl, she won't do any of those of course, and just let you bust your load deep into her throat, while she is trying to survive the onslaught of your manly rod. Face fucking for president, of course, no pun intended!
