She's Kidding, right?

"Ok, like I said in the cabin, don't be gross." I rebuked her gently.

"Brent, don't fucking lie to me, It turns you on, and I can tell." Charlotte sighed, stroking her hand along her chest. Her eyes dropped to my crotch. "You're fucking hard right now, just talking about it, so please don't pretend. "

"Ok, but it's just a fantasy." I nodded. I admit that I was hard as hell at this point, and Charlotte's subtle movements in the seat next to me were not helping.

"Sure as hell isn't for your sister," Charlotte giggled. "From what I read of those texts, I seriously had no idea she was your sister. I'm sorry, I'm nosy and didn't ask. "

"What if I said that I was still kinda pissed about that?" I commented dryly.

"I'd say, sorry, I'm wearing your clothes and no panties, and if you want to take it out on me we could always find a place to pull over and let you have what we both wanted last night but were too chicken to do. I know what you really want to do to me, Brent."

I swallowed nervously. That fantasy of her pregnant ran through my head. The thought of claiming her totally, mating with her. It was always there in the back of my mind, but to have her acknowledging it...

"You want me to say it? I can say it, Brent." Her hand drifted to the buttons of the blue and green shirt, slowly beginning to undo them. "I really am fucking horny and the thought of it... Are you looking for a place to pull over yet?" I glanced over and noticed her hands sliding over herself, pulling open the shirt to reveal her bikini clad, gorgeous breasts.

"You know we're on a deadline here. I can't do it like you deserve. And I thought you didn't want to do it in the back of a van."

"If you want to turn me down because you think I'm not allowed to change mah mind..." Charlotte laughed. "Look, we can pull over, you can fuck me, I can pretend to be your sister, and you actually deal with her like family instead of your girlfriend, because let's be honest, she is playing you like Galaga. "

"That would just be too creepy. I want you." I blurted. I couldn't go that far. That would be just wrong. Besides, using Charlotte to deal with my sister? How could I ever look her in the face again?

"Oh, so you want Charlotte, huh?" She smiled, reaching her hand around the back of her neck and causing her breasts to heave beautifully. Damn, she knew how to use what she had, and was using every bit of it. "I do want you that way, and you've already had a sample... You want to go all the way with me? You want to come inside me? I know that turns you on. Coming inside of women. You had a lot of searches with that. You want to take a chance?"

Her voice was taking on a sultry tone that she didn't use with her southern accent. There was still the sexuality inherent there, but there was something more genuine. She was enjoying the game, enjoying seeing how uncomfortable it was making me. She knew I wanted her, and was trying to eke every moment she could out of it. To be honest, I was getting a little bit of a thrill out of it.

"You know Kaila and I are trying for a baby." I swallowed heavily. I had thought the previous night would have taken almost everything out of me, but somehow despite the sore muscles and light bruises on my chest, I could feel my ardor rising again.

"I know. And it turns me on. Thinking about how last night you were breeding her with my girlfriend watching." Charlotte grinned. "You seriously not going to pull over because it can not be easy to drive that hard?"
