Update: Sister in-law trouble.

You can check my post history for the background info on this.

Shortly after I posted yesterday I decided to hop in the shower. I told myself it was to clear my head, subconsciously I think it was hoping Sue would come home during and find me there. She didn't. I got out, threw on so relaxing clothes and took it as a sign I need to talk to Sue about what's going. I paced and wandered around the house waiting to hear Sues car and after about an hour she pulled in the driveway.

I watched her out the window sit in her car and check her phone. I panicked wondering if I should head for the door, wait in a room I know she'll be in or see if she finds me. I decided to go to her and made it as far as the landing on the stairs. I heard her come in and froze.

Sister in-law trouble [M/F]

My sister in-law (I'll say Sue) has been staying with us for around a month and a half while her house is getting renovated. My wife and I have a great relationship with her. She's a few years younger than us we are both late twenties. It was fun having her around doing things we don't normally do the first week. Staying up late having some drinks and talking, going out together. Stuff when it's just my wife and I don't bother doing. We were up late talking one night and my wife went to bed early leaving us alone. We kept talking and soon it drifted to sex. Sue didn't ask much about her sister. I just assumed she knew everything already, they're close. Then she asked me if my wife had any kinks. I didnt give up much but she does have an obsession with being rimmed. She was intrigued and we talked more about that. She asked me what kinks I had and feeling brave and tipsy I told her one I've had bottled up forever. Assplay. I've always wanted it done to me and have never had a partner willing. She was surprised and couldn't believe my wife had a similar kink but never returned the favor. I told her of the one conversation my wife and I had about it shortly after leaning of/fulfilling hers. It fell very flat and we never talked about it again. She started asking what I wanted and if I ever did anything alone and I felt a bit uncomfortable. I gave some quick answers and feeling exposed I did my best to get to bed.
