I have to admit, as a pedantic mother fucker, that one bothered me a bit too.
Normally I would agree with you, but in this case, she doesn't take anything off at all, just whips her tits out, so I would call that 'normal' not 'nude', especially once you unlock the other outfits. It is a bit jarring when she is wearing less that than before you ask her to start, then when you ask her to be 'nude', and she gets dressed. I mean, she wears that rope outfit most of the time after all...
Hahaha...
Sorry, had to throw my two cents in there as well. Either way, I like the maid one better anyway, she calls him 'master' in that one, it's cute.
