I actually did these a few weeks ago that was basically just a silly idea to kill some boredom. I only just remembered to post em on my blog the other day.
Started by me thinking "what if these hentai anime were uncensored" and so I took a few screengrabs of various scenes from four random ones I have that I re-watch from time to time to be inspired by as it were lol. My goal was to simply redraw the parts that the japanese government doesn't want people to see and I think I did an ok job.
The original scene is at the top of each pic with my edits below. I dunno about you guys but it sure does as always make me think "man why on earth does Japan still have that dumb law". Oh I know the answer but that doesn't stop it from remaining one of the dumbest things ever.
I would even go as far as to say the reason Japan has always created so much porn is because of said law, its almost like its been decades of mass compensation. "they wont let us look at naughty things so we're going to create the naughtiest things EVER gosh darn it!" Quite ironic if that were the case.
Anyway here's the details for those of if you're interested in tracking down the sources of these, I certainly recommend all of them:
Scene 1, from Himekishi Lilia: episode 3.
Scene 2, from Kanojo X Kanojo: episode 1.
Scene 3, from Kuroinu Kedakaki Seijo wa Hakudaku ni Somaru
Scene 4, from Viper RSR, which is technically a video game but the animated scenes and gifs of said scenes have been floating around the net forever along with the billion other Viper games that were made. Google Sogna (the creators who went out of business years ago sadly) and Viper and you'll find em all in some form or another.
Fun fact!: Takahiro Kimura was the lead character artist and animator on the Viper games, he's worked on such anime as Godannar, Gun X Sword, Code Geass, GaoGaiGar, Big O, Bastard, Dirty Pair, Golden Boy, Girls Bravo, Lupin the Third, Kiddy Grade, Macross, Naruto, Gundam, Jin-Roh, Wolf's Rain and well a lot more.
His animation style is a bit trickier to notice but you'll certainly know when he's the one in charge of character design, like me he's a fan of curves and exaggerated figures/proportions.
So I'm a huge Kimura fan if you couldn't tell. My art style I would say is somewhere between 50 and 70% a ripoff of his most of the time haha.
