Hi, I love your work, I’m a big fan, just lurking in the shadows :)
Two questions: one, is Josie an actual inflatable woman or does she just have a valve? And two, have you considered Josie deflating/popping?
In answer to your questions; yes Josie has an inflation valve that inflates her breasts. She can inflate and deflate whenever she want's / needs to. I have never considered popping i'm afraid, in her lore that would be impossible.
