Animated flash version at post #143861

Are you sure it's a male? :?

I've got no clue what book this is from (as it does seem to be from one) so I can't confirm anything, but I think it is, yeah. It could be a futanari, but I'm more inclined to think it's a boy just because of Po~ju's tendency towards very feminine-looking shota.

You can also see that he has a penis if you look at the bottom right.
