Someone I believe must edit the housewife tag to point out that if there's adultery or cuckoldry, they need to tag that too. At this point they think they can just tag 'housewife' and move on.
For future reference please use this thread for all tag related issues (just no new tag suggestions please!):
FAKKU: Tag Edits/Corrections
To answer your question:
Netorare
Netorare (å¯å–られ), also referred to as NTR or cuckold, is a genre where the intent is to cause an emotion of deep jealousy or distress in the reader. A direct translation of the word results in the definition "having your lover taken from you" or "to have something taken from you while you sleep". This is often accomplished by having main protagonist's loved one seduced away from them, with or without their knowledge.
Housewife
Housewife is a term used to describe a married female who is not employed outside of the home, instead she manages the household while her husband works. Manga with this tag involve housewives while they are at home. Additionally it is used in place of a MILF tag.
I do think that the housewife term should change or there should be a milf tag and I'm talking to Jake about tags atm so things may change.
As for the two works you linked the first one by Tachibana Omina, I added the appropriate tags (also put it with the first chapter into a collection), it did indeed need the housewife tag.
As for the other work you linked, it does not need the housewife/milf tag. The women may be older but it is not the focus or fetish of the work. Milf and houswife is a unique fetish that deals mainly with a woman's age in comparison to there activities/partner, similar to how pettanko is the focus of small boobs or loli is a certain age/appearance.
