Your step-sis asks you to come over for a chat. Strangely, she’s in her bedroom wearing a robe and lingerie, rubbing baby oil onto her body. You’re confused and ask her what’s going on, and she says her skin is dry. She asks, “why, do you want to take a picture?” She continues to apply the oil, and asks you to rub it in. You’re not complaining, but you have a bad feeling. She finally cuts to the chase and asks why you have sexy pictures of her on your phone. She’s pissed and says you’re fucking disgusting. You explain that things have been tough with your marriage lately and you haven’t had sex in a long time. After some consideration, she feels bad for you. She decides to be a good big sister and lets you see the real thing. She begins to strip down slowly and asks you to tell her why you like her body so much. She asks if you’ve been perving on her for a while and you admit it. She asks if her tits and ass are better than your wife’s, and you admit that as well. After showing off her tits, shaking her ass and stripping completely naked, she sees that you’re hard. She decides to help fulfill your fantasy a bit more. You sit down on the bed and bounces her butt on you, rubbing your cock between her cheeks. She then tells you to titty fuck her as well. She says that you have a really nice dick, and had she known, she might have had pictures of you on her phone. Once both of you are worked up she lays on the bed and tells you to fuck her missionary. Her pussy feels so good! While you’re fucking, her phone rings. It’s your wife. She answers, telling you to continue but be quiet. She tells your wife that she’s still having a serious conversation with you, but she’ll call back later. After hanging up she tells you that your wife is the one that told her about the pictures. She tells you to lay down so she can ride you reverse. She wants you to only think abut her ass when you fuck your wife from now on. She bounces her big booty on your dick and when you’re ready to cum, she has you pull out and shoot your load all over her ass. After, she takes some pics of the cumshot and her naked body and texts them to you. You better hide these pictures better this time!
