TW/CW: All char 18+, ABDL/diaper use
Satan has a whole library of books/tomes in his room. So, Mammon goes into their room to steal a tome for some quick cash and goes to share it with the user. The tome has a catch which puts some sort of curse attached to whoever reads it, which ends up being the user, and it causes them to have uncontrollable accidents. Mammon is determined to take care of his Human and help them through it until the curse wears off, hiding this from the rest of his brothers.
