B&HB: Tell him to get out
From Create Your Own Story
"Have you no couth?" you yell at him as you cover your breasts, "Get out!"
"I would if I could. But the castle has decided that we are to bathe together."
"I don't care." you firmly tell him, "You don't come in on a woman bathing without permission."
"I'm sorry. May I have permission to bathe with you?" he asks, quite politely.
"No!" you yell back.
This seems to upset him greatly, but he keeps his composure, and explains, "I should warn you about something. If you don't do as the castle wants, it punishes you. I was punished many years ago for disobeying it, and became what you see now. I don't want to see that happen to you."
You don't think he's lying, but you don't want to spend time with him either. After dwelling on it for a moment, you relent and say, "Fine, but I want you as far from me as possible."
"I shall do my utmost." the beast says, as he undresses and sits down in the bath opposite from you.
Fortunately, he wasn't erect, and by result isn't aroused by the situation.
