Xa2m
Xa2m is an acronymn that stands for “eXtreme ass 2 mouth”. In traditional a2m the penis is removed from

the anus following anal sex and put direclty into the reciever’s mouth. Xa2m is much like a2m, but it differs in that the penis is covered with the product of a fresh bowel movement.

Following the Xa2m scene, the porn star had to undergo treatment for hepatitis.
