This isn't Moriya Makoto. Not quite sure who the artist is, but it ain't Makoto. Doesn't look like any of his early stuff (as Maeda Takaya and Naruse Yoshimi) or his new work. The boy looks nothing like a Makoto boy; the mother looks nothing like a Makoto MILF; and her tits, though oversized, are, without a shadow of a doubt, not Makoto tits. Guess again.
