You love the idea

"I love the idea!" you smile and answer without hesitation. "It's what I was born to do. I'd even be a willing participant in helping childless couples have a baby. The brothel, the on site nursery, everything. It just feels so right, and it turns me on at the same time. In fact, I'm still so turned on I want you to put another load in me to make sure I am pregnant. But, how do I explain all of this to James?"

"Leave that to your sister" answers Robert. "She's going to work him over real good tonight, since you're not going to be making it home. She's very persuasive, and she'll talk him into joining our little group. I think he'll be happy being able to fuck anyone he wants to, including you. You'll probably even be able to stay married to him after she works him over. He's a man first, a husband second, and Sarah knows exactly how to handle men. She could even talk him into having a foursome with us. That I don't doubt."

You know Robert's right. Your sister is very persuasive. After all, you're here right now because of her persuasive powers. "Well, I can't go anywhere any way. It seems I don't have any clothes to wear. So we may as well stay here and fuck all night to seal the deal." you slide your hand between Robert's legs, and give his cock a playful tug. It springs to life as it twitches in your hand. "Oh! Look at what just came up!" you say in a playful voice. "Ready for another round?"

"I'm ready to go for as many rounds as you can last for" says Robert as he takes you into his arms.

"Mmmm, now that's what I like to hear!" you exclaim. "You, sir, are turning me into quite an insatiable slut."
