"Don't worry, we'll switch back midnight Saturday, July 21st." Great, the weekend of the town carnival. Everyone was there. Shit. "C'mon, let's get yo... dressed," she said. "We need to teach each other how to be each other over the weekend." I could tell she already had today's outfit planned out by the look in her eye. She opened the first suitcase and threw me some black silk panties. I just stood there, gasping for breath. She sighed, and came over to me. "You put them on just like your. “Yes we can,” I replied, kissing her. She kissed me back, licking her taste off my lips. “We shouldn't,” she moaned, kissing me harder. “We are going to,” I stated, pushing harder against her. The thought that I was going to fuck my sister rose in my mind. The naughtiness of the words made me hornier. “Jackson no,” her mouth said while she moved her hips, letting my cock slip into her pussy. I thrust into her slow, savoring the feel of her tight, wet pussy. She moaned, urging. I focus on his upper body, finding his erect nipples and slowly swirling my tongue around in a circle. I suck gently on each of them and take a tiny bite of the skin between my teeth. He groans and his body jerks. I move down his belly, and work my tongue around his belly button. My hands are roving up, down and around his upper body. I lick below his belly button, slowly following the trail of hair which leads to his groin and stop. I spin my body to face the other way and start kissing his. Instead she opened her legs wider for him."Baby you are doing so good, Daddy's going to make you feel so good," he croons as he starts to slowly thrust in and out of her. Even with only half of his cock inside her he can tell that she has an amazing pussy. He can't recall having a cunt as good as this since her whore, mother left. He picks up speed, and she begins to moan under him, her pussy gripping his cock each time he pulls back to thrust forward.The initial pain starts to fade giving way.
