How does this sound. Friday, I take you and Kaia to dinner and a show on Friday, let you two get comfortable with each other. Then, we get a nice hotel, and you and I make sure it's a night that she never ever forgets.
Then Saturday, you join me and Professor Fischer, Taylor, and you do whatever she wishes while I either join or watch. I'm sure you'd enjoy her attentions, though she does break out a whip now and then.
