what a question, thanks for reaching out^^!! unfortunately don't think it's something katie would particularly pursue, if anything i can see her putting a camera in the potty or something similar that wouldn't require phoebe's knowing partipation. if anyone wanted to commission me for some katie/phoebe scat action, though, i could definitely see ways for her to make that happen! katie's totally the type to fantasize about phoebe using her face as a toilet, and in her more sadistic moments, using phoebe as a toilet. Again, probably nothing she'd pursue that hard unless phoebe started showing interest, which would be an interesting turn for her at such a young age 😅

Sorry if that's not the answer you were hoping for, but thank you for the ask!
