While I don’t watch Fairy Tail anymore (due to the story seemingly going nowhere…), I did hear about Erza Scarlet’s age-regression misadventure, and was inspired to start a sketch which turned into a full blown drawing.

Humiliation, Spanking, Diapers… A page of outrageous fetish fantasies. Only meant as empathetic fantasies for BDSM enthusiasts, and all fiction, thankfully.
