>>1644009Some potential ideas for a way of getting the princess into ENF situations:
Her spellcasting is fuelled by clothing, so she needs a continuous supply of garments in order to cast spells.
In order to keep up with rapidly changing fashion, she wears only a magic item that generates illusory clothing, to save on elaborate outfits which are only worn once. Unfortunately for her, outside the castle this requires immense concentration to use.
She gets cursed with a sexual equivalent of the movie Speed. Should her arousal level drop, her clothing starts disintegrating. Bad things happen if the curse runs out of clothing to consume.
