You have had your sister-in-law stay with you for a couple of weeks now.. but you can't stop imagining what it would be like to be inside this woman. You watch her walk around and listen to her chatting to you but all you think about is her pussy and how different she could be in bed compared to your wife. She is left alone with you one day when your wife heads off to work. She tells you that she is aware you look at her and that she knows you don't get fucked as much as you use to. Before you know it, she's slowly sucking your dick on her knees, then you have to do some serious edging as she starts to fuck you. She is so tight! Your wife walks back in but she laughs it off whilst bouncing on you and playing with her tits. Its too much for you and she asks you to cum on her face whilst your wife watches!
