A lady friend and I once made up a goofy scenario where Rosetta walks in on Mist using turnips on Raguna in disturbing ways, and Rosetta has to be all "No, bad Mist, that is not how you use turnips!"
... I think she said she'd write a fanfic about it. She never did.
I was imagining it being like this, except on herself. I've heard of women using phallic-shaped fruits and vegetables to masturbate in place of commercial devices, so this seems reasonable enough to me.
