Makes you seduce her.

She strips off her jacket and turns around. She raises her skirt up a bit, showing a little ass to you.

"...what are you doing?"
"I'm getting comfortable. Does that bother you?"
"It just... feels...inappropriate," you say.

She ignores you and keeps stripping.
The blouse goes next, and she slides her skirt off.

"I'm just going to go," you say, "This isn't right."
"Fine. Go. Just remember that I'm going to be naked, and you will be seen leaving my office. What are all of the words that start with 'R?'

You stop walking and look back at her.

"So... what do you want then?"
"I want you to prove that you're good enough for my daughter."
"How?"
"Eat my pussy. Make me cum," the Dean explains, "If you please me, I'll see how good you can fuck me too."
"And if I don't, you'll cry ****, and my life is ruined. I suppose this seems like an easy call."
