when person A proceeds to give what person B thinks is a blowjob, then simply holds the head of the penis in her/his mouth and proceeds to jerk person A off without actually doing anything with their mouth but holding the penis in it.
I was so happy that chick was finally gonna suck my dick then the bitch pulled a head fake on me.
When a female performs oral sex on a male. The motion that is done with the neck imitates a basketball player when he fakes out an opponent by using his head in quick jerking like motions to fake them out.
Oh you know Mary is really good at throwing the head fakes.
