The Best Landlady (diaper version): An ABDL/Sissy Baby book

Martin was a solitary young man who was about to be evicted from his run-down apartment, and this presented real challenges. He couldn't afford a house, and most places rejected him because he wore nappies/diapers as he was still a genuine bedwetter. But that was only the start of his quirks, and the idea of finding a new place to live was horrifying. But then he got an offer to board with an older lady who apparently was tolerant of diapers.

What could possibly go wrong? Or right?
