I don't think this one should be considered a ntr, because she didn't fell for the other guy (I think), she is just having sex behind her husband's back.

I... I...
wait, i cannot tell if this is Netorare.
In heart and nature, this is indeed Netorare.
But the way she is treating sexual intercourse,
she is not metally hurt or distressed by sleeping with another man.
The reader don't feel particurally bad either.
Personally, i don't think this is Netorare, this is just a slut story.

what will you do if you already have a wife, and your wife having an affair with another man? You must be sad, isn't it?
is it true in a mind of every woman there is just sex? the answer is no.
I just like the picture only. XD

The source is an (milf?) anthology called 孕み妻 (Haramizuma), but only this chapter is found on the internet. The chapter is also present in a tankoubon but with different page numbers.

Chinese version of the anthology: /g/438933/d443d76386/

This husband needs to take care of his horny wife, he's so stupid for neglecting her.
