Feet!

"Feet?" asks Raven.

"Yes. Feet" he answers.

"What about them?" you ask.

"She" he points at Raven "will lick your feet. And you'll be pleasing me orally. Maybe later we will switch."

"This is getting too far" Raven protests.

"You want to lose another round?" he asks calmly.

"No I want to get away as far from you as possible!" she announces.

"And how exactly do you plan to do that? Being tied up and blindfolded."

"I'm not doing this."

"So, you'll lose another round."

She falls silent. You know that she's considering her decision. Either she will try to keep some part of her pride and she will lose another round or she'll swallow her pride. From your perspective it's a win-win, either this bitch will get to lick your feet or you'll win another round.
