You, the prince/princess, are bathing. Your knight is standing guard outside your chambers when you call for him. You tell him you “forgot” your towel, and ask if he can fetch it. You then ask (order) him to stay while you dry off. You can tell he’s trying to keep it professional, doing his best to not stare, but he just can’t help it. Once you’re dry, you lead him to the bedroom, beginning to touch yourself because he clearly can’t take a hint.
