Backfired plan (Patreon)

Ruler Moriarty wanted to get back at his older self but in the end the old man was smarter, and now he has to deal with a non-stopping growing booty!

In case you might have forgotten, Ruler Moriarty was the runner-up on the FGO Rulers poll, and as such here is his drawing! These butts have just keep getting bigger and bigger don't you think? haha, hope you enjoy it!
