You know... I intended for this to be a sexy boudour style pin up pose. I wanted to do sins. But the sins wouldn't happen XD. Then again Undyne isn't really the sort of lady that would do that sort of thing unless Alphys wanted it.
There's a few things I like about this piece, and more than a few things I don't like. But hey, Ya'll wanted fish wife, you get fish wife. Ya'll didn't even ask for sexy fish wife? TOO BAD :P
Mature for fish nips.
