Fairy Dust (Patreon)

I really liked that fairy design and wanted to show her current predicament! After returning home the spell worked as intended and the whole world see's the adult princess as nothing more than a diaper wearing brat. Her parents hire a mouse nanny to take care of their Princess, and to make things worse -- a second part of the spell kicked in when the fairy returned home, her magical powers and wings both disappeared.

Today the Princess suffers her most indignant shame, a diaper change followed by a spanking.

It's gonna be a long ten years for the Princess.
