(Picture not related)Since there doesn't seem to be a futanari section of 2chan, I was wondering: Is there some Japanese image board that produces futanari pictures at a reasonable rate?
Looking through my bookmarks, there used to be several, but they're just giving me 404s now, sorry.
/d/ is the futanari section of 4chan. There are certainly enough girl + penis fans here.
