I said that I understood about her need to see Claire, and I didn’t see that as cheating on me as it was out in the open. She kissed me passionately... before making her way down my body and taking my clitty between her lips, As she sucked on it, she took hold of the vibrator and turned it on and held it against my pussy. I lay back in ecstasy as she worked my clitty and pussy together, building me up inside. Then she surprised me by taking the dildo off and lowering herself onto my clitty/cock,. I just need to talk to him about my last paper. Please be on your best behavior.”“Even my best behavior isn’t very good,” she joked.“I just mean that you should try to make him feel comfortable. After all, he’s your professor too.”“I promise that I will try to make him feel comfortable.”For some reason, the tone of her voice made me question her intentions.Jennifer and I spent the morning cleaning around the house and messing with each other. We had to stop for a blow job break and a quick fuck. There is something so completely taboo, something you don't want to admit to yourself, but all the focus, all our eyes, are just on his dick and her holes. Dragging (barely) my eyes away from their fucking, I looked at Ben at got even more turned on when I saw him looking down at his dick fucking her ass. Knowing how much he loves when I talk dirty, I said "baby, are you looking at her cunt while you fuck?" Continuing to pump his dick in her, he said "Yes yes I wanna see it cum" I told him,. Now most brothers might find the thought of their sister being hot totally disgusting, even revolting. But I always thought my sister was a goddess, a slutty goddess sent down from heaven. When I say slutty, I mean slutty. She was always in yoga pants or short shorts while wearing a tank top or a cut shirt where you could always see her thong or G-string. My parents didn’t mind because they were barely around. But whenever I saw her I almost always got hard.Just as the movie started to end.
