Make her a mistress

It's not every day you find a girl like that. You feel no desire to marry her, but you don't want her working in the fields like a normal peasant. Much better to have her working your cock. Plus, if you sire any bastards with her it would be easier to keep track this way.

You decide on this course of action, but as you do a thought makes your blood run cold: how does one take a mistress? I mean, what bridges the gap between scandalous affair and wordless acceptance of sin? You ponder this question with great intensity for some time.
