When you suck the shit out of a girl's asshole during sexual intercourse.
Dude I was so blown last night. This girl i was with was super fine but she would only suck my cock if i san francisco 49ered her. it was totally not worth it. i still got pieces of shit in my teeth and can feel it rumbling in my stomach.
