Plus, the lactation doujins practically write themselves.
One thing that I've wondered is that while they have adult male, adult female, and loli draphs illustrated, I wonder what a male draph of grade school age would end up looking like. Are they always ripped, or are they more or less the same size as females until puberty hits and suddenly become muscle mountains?
Also, we have elderly draph men in the game, but no elderly draph women. I'm curious how they age.
