How do you NOT have sex with that Beauty of a wife for a long period of time? That Husband must be a fucking loser.

Sometimes I have to wonder if western 70s porn is still a relatively new thing to Japan. Because this is plucked right outta one of them.

You have to remember that they're in a 2D universe people. So the wife probably is to the husband what 3D people are to us which makes things a lot more understandab-nah can't really justify why husband is giving up dat ass for porn.

You can't just pull someone pants down and not expect to pay for that. You got to give him ass now.

...Uh, what? They start having sex and then out of nowhere she's calling him Master? I mean, I know it's your fetish but you still need to have a little set up for shit like that.

@Ishmon:

Or, you know, the writer wrote it that way just so it could happen.

Seriously, why are you looking for sanity, common sense and realistic situations in a doujin tagged "netorare"?

9 times out of 10 none of them have anything resembling to realistic reasons for shit to go down the way they do in them.

Yeah the husband/partner needs at least some kind of vague awareness/suspicion of the situation for this to be classified as NTR. As it is now, it's just plain cheating.
