Depends.

If you are a sadist or a masochist, then House, so you can beat her every time she won't shut up or you can punish yourself by listening to that.

Run of the mill degenerate, Field, so you can hit her in the back of the legs with a switch, lift her tattered dress up, and get some plantation style luvin before you get back on your horse and ride to the saloon. Of course the stench from unwashed field slave ass would probably lend itself to missionary position. When that is taken into consideration, I guess a BJ behind the outhouse would be your best bet. If you have a good horse, you could sit on it sideways and let her stand while she sucked you off, like an 1800's car date. If it is a really good horse you have, then you should let him get sloppy seconds.

And FYI, in her writings, she considers her self a field slave.
