Propose her to get a corporal punishment

"So at least you care about being ****", you say. "You still have some kind of pride, so", you add. "Well, my proposal is that you get a proper corporal punishment from me, and I don't call the police. It's gonna hurt, and probably your skin is gonna bear marks forever, but you'll remain a pure virgin."

She shivers.

"Sir, please... Don't beat me. Actually I don't mind loosing my virginity. I don't want to be **** by brutes, but you don't look like a brute. Have me. Make love to me. I'll be good to you", she says.

"What is your name?" you ask.

"I'm Alice", she replies.

"Alice", you say. "I personally mind having sex with the little slut you are."

"Oh!", she says angrily.

"A little slut. Perfectly. That's what you are. Sure, those guys who **** your sister were bastards, but you're not much better than them."

Alice starts crying.

"Well, I suppose I should call the police then", you continue.

As you are taking the phone in your hand, Alice speaks.
