This happens during rough sex when the female gets extremely wet and the man is thrusting the entire lenghth of his fuck stick in and out of her gushing gash. He then gives her a good jam and unknowingly enters her backdoor and slides all the way up her turd tunnel. Generally, this will force the session to come to an abrupt stop as the woman struggles to catch her breath, while the man rinses the kidney bean off the end of his purple headed yogurt slinger.
