The Erotic Adventures of a Victorian Doctor

What must Lady Juliette be willing to do in order to have an erotic threesome with Doctor Damian Thatch and his maid?

Damian has, to this point, been content to satisfy his sadistic nature by dominating Rosie, his maid and private dolly mop. But since he has developed a romantic relationship with Lady Juliette, he also wants to to include her in other aspects of his sexual life. Juliette is playful and enjoys being spanked, but Damian has yet to broach the subject of having her become submissive to him. However, her interest in Rosie may provide him with the means to do so. And a threesome would be a plus.
