[Request] Porn Story: Mother in law and mother arrange for cuck wife impregnation

I don’t remember what it was called, but the general plot:

Wife’s mother/protagonist mother agree that they’ve had long enough – it’s time for the wife to get pregnant. They arrange for a bull to breed her while his mother gives him a handjob. Husband and wife are reluctant, lots of talk about a “real man” breeding her and how he’s had long enough, so something must be wrong.
