When one gives oral intercourse to a male partner while supine, with the scrotum inside the mouth and the tongue reaching down to as close to the anus or the perineum as possible. The sloppiness comes from the salivary secretions as lubrication.
when a guy is fucking a girl from behind in the vagina then pulls out and goes into the ass, the girl gets shocked and climbs up the wall in a goanna like fashion.
last night i was rootingchristy against the wall and i wanted some ass so i went in for the kill but she got so shocked she climbed that wall like the goanna!
