I think we are all aware of the hate these two have for one another. How about making a series, Porn Feuds.

Volume 1: Mandy vs Missy. Start out with both of them smack talking, and then perhaps a cat fight or some hair pulling. Let them go at one another with strap-ons on a 5 minute clock. And finally get them in position of face to face with one another in doggie position and break out the meat puppets for deep anal drilling with PLENTY of ATOGM. The first one to or break down to loses.

just a thought
