Hat ein arschloch einen thread?

This time it was about finding out whether my girlfriend's cute asshole actually has a thread into which you can screw a huge screw. This toy is really huge and we didn't know if she would make it. The result: the hole has no thread or at least it is already worn out properly and the rosette remains really wide open after such an extreme treatment and her horny pussy is totally wet. This is really awesome assplay. This is Marcus Pollack!
