It denotes the act of fixing undesirable aspects of a work. In the case of adult-oriented art, it can also mean adding black censor bars and mosaics.No, no, you can still see bits and pieces through the censor! If you aren't okay with the front, spreading your back hole works toooo!The 'back' isn't considered a sexual organ if there's no penetration, so in those cases not doing any retouching is fine too.Heeey, Kazaguuuumo! Spread your lips a bit, will yoooou! I need a reference, okaaaay!Show us the creases too!!—wait, that's still no reason for me to show you, huhh!?Aww, it didn't work...Seeee! The back hole is OK, as she says!
