This chapter brings up a problem I wasn't thinking about. Sure, Ax could just say he needed to go to the bathroom near the two hour limit. But after he demorphs and remorphs, his orifices go back to being tight. I'm not sure how far he'd get with the "I tightened myself back up" excuse, but I can't really think of anything better.
Maybe there will be drinks there, and the guys will be too drunk and horny to notice or care.
