She asked me what kinks I have and, feeling brave and tipsy, I told her one I’ve had bottled up since forever: Ass play. My wife isn’t the kinky type so there was nothing much to say about her. My sister-in-law started asking the things we enjoyed during sex and if my wife and I had any kinks. We kept talking and soon, the topic drifted to sex. At some point, my wife left us and went to bed, leaving the two of us alone. One night, we were up late talking as usual. Just basically stuff we don’t bother doing when it was just me and my wife. Such as staying up late, having some drinks and talking, and going out together. Generally, it was fun having her around as she made us do the things we don’t usually do. She’s a few years younger than us - my wife and I are both in our late twenties. My wife and I have a great relationship with her, so it hadn’t been an issue when she asked if she could come stay with us.
