Well, it would be kind of difficult to tease him about it and still keep it secret from him.  Especially if she tends to always be naked (er, how often are pokegirls naked in public?)  Perhaps she always preferred to be wearing little/no clothes, just not when she was around other people, so thresholding only got rid of her modesty, not her whole personality (and really, when you make everyone nearby want to have sex with you just by being near them, modesty will probably go away pretty soon...)<br/><br/>Edit: Gonna go with this for now, I'll hash out more details with you later and change things if needed, Hollow.  Yell at me on IRC if you see this tonight.
