Here’s an Insert copybon from C79. It’s apparently a parody of a manga, although I’m not familiar with it. Enjoy!
I think the manga is Maken-ki by Hiromitsu Takeda. It’s a decent boobs/fighting manga.
Takeda draws porn.
Takeda draws Maken-ki.
Insert sees Maken-ki.
Insert draws Maken-ki porn.
Funny how the world works, sometimes.
Same thing applies to all the artists drawing High School of the Dead porn… :)
