What is Housewives manga?

A housewife is a mature woman (should be out of high school age) who doesn't necessarily have to be married in our context, but typically is. A housewife doesn't work (depending on context, she would be an Office Lady instead), however, since we're not as much down to technical details as we are of visuals, that restriction can be discarded if the character in question is shown mostly in home environment wearing leisure time clothing or a kimono and an apron can also be safely added to the bunch. Almost completely exclusive to hentai animations.
