The thing with massive boobs women in hentai stuffs is because societies has this somewhat annoying notion of "small/flat chested women are loli/underaged" no matter what their bio says otherwise.i agree 100% with you brother, but if alot of fans ask for it maybe he consider make one
Same goes for a "non-muscular hairless sub male considered as underaged male".
This problem can be seen generally over reddit.
P.S:
So there are other doujin artists had to draw huge breasted females so they won't get into trouble with the law
