to see how badly she wants it

I wanted to see how much she craved sex with me. "How badly do you want me to fuck you?" I asked.

"I want you sooo badly!" she said.

"Bad enough to beg?" I said.

She dropped to her knees. "Please, I just...I need you to fuck me! I'm so horny! You have me so hot and horny!"

I could sense a bit of shame and confusion amid her horniness and desperation, and that turned me on even more than her naked body.

I stripped naked. "OK, give me a rim job first." I turned around.

"What's that?" asked Vivi.

It figured a high class dame like this would not know what a rim job was. "You tongue out my asshole. Lick it and probe it and try to stick your tongue up in it. Do it or no sex."

I twisted a bit to see her. She looked a bit scared and repulsed, but her chest was heaving, and she was horny. Her pussy had started to leak.

"Um, OK, I guess," she said.

I twisted back around. Soon I felt her tongue tentatively probing my asshole then she started to go at it with more gusto. "Yes, this turns you on. You love this." I said. I heard Vivi moan and the fact that something she probably found totally repulsive just a short time earlier was turning her on. "Keep it up. You're good at it. You're a great asshole licker. It's amazing how nasty you are that licking an asshole gets you so hot!"

She moaned again, and I wondered if she still felt any shame. Vivi kept it up for a while then pulled back. "Will you please fuck me now?" She pleaded.
