For the past few minutes of slowly going
through an mental de aging process thanks to Harley
Joker has been whining and complaining nonstop.. Until she shoved an adult size dummy/pacifier into his mouth and since Joker has lost the mental strength to pull of spit it out he's just going to have to put up with it.

I enjoy the subject of mental age regression
But I don't consider it a fetish
So no hate please
