You walk downstairs late at night to see your sister in law standing in your kitchen. It's your wife's family reunion tomorrow, so her sister is staying with you two for a few days. Your sister in law seems really happy to see you. The two of you begin chatting with one another and you notice that she is being kind of flirty with you. It doesn't take her long to admit that she has been attracted to you since the two of you first met. She continues to tell you about how she believes that you should have gotten with her instead of her sister, but you met her sister first. You are surprised to hear that she also knows all about the issues between you and your wife, her sister. Like how the two of you never have sex anymore. She also comments on how your wife has been letting herself go, something that you have also noticed, especially now compared to her much more attractive sister. "I know that you are a man who needs sexual release" You do. You have so much pent up sexual energy, and your sister in law's eagerness to suck you off, the way she is praising you, and her overt bitchiness about your wife is getting you rock hard. Then, she takes her top off. You've wanted to see her topless for years and now you are finally seeing it. Your cock is harder than it's ever been and you need her mouth around it. She doesn't disappoint. She gets down on her knees and begins giving you the best blowjob you have ever received. Knowing that at any point your wife could walk in the kitchen to see her sister blowing her husband, thinking about how this is the kitchen your wife cooks you breakfast and dinner at everyday, it all turns you on even more. And you sister in law knows this. As she slobbers all over and sucks your cock she comments on exactly what you are thinking. She talks dirty to you and makes you feel better than your wife has ever made you feel in all the years the two of you have been married. She even tells you how if you were to leave your wife for her, you would receive this special treatment on a daily basis. Soon, she is getting off her knees and pulling down her shorts and underwear. You begin to fuck her rough from behind. She keeps on moaning and at this point you don't even care if your wife sees the two of you. You almost hope she does. After fucking her from behind she turns around and you push her up against the counter top, her small breasts bouncing sexily and her leg lifted up onto the counter top until you are both cumming together.
