Natural Mama [English], by Nakayama Tetsugaku, has been DECENSORED! :)
Well, I’ll make it short. I found the uncensored version of this shotacon work. The story is a huge meh (mother-shota son = total loss of interest from me), but I have to reckon the art is very good, and hentai is always better without censorship.
Same old link as before, only with updated links this time, enjoy
