The good thing about women is that as long as you're Man enough to actually treat them like the bellies and tits they are, they'll essentially train themselves to be your personal breeder, the sign of a good cow is one that you barely need to lift a finger to train.
Of course once you're flooding her womb with your thick, misogynist cum, the training will all wash away in favour of a baby-addled, foggy brain, but that's okay, she'll be dumb enough to just do what you say once her belly starts coming in.
