Anyone ever read the h-manga about the housewife and her husband running a bath house where there are "special" washing services. The male mc runs a service to get his wife pregnant because he has low sperm count due to getting baddly sick in the past( of which the wife blames herself because she's the one who got sick). There's also the MC's mother-in-law(who originally ran the service) and a gyaru housewife. Series ends with MC getting pregnant.
