She married my brother when I was fourteen and way back then she used to flirt with me, just to make me blush. It amused her and my brother both. For instance once, while visiting them I was sitting on the living room couch and she was showing my brother the sexy undies she had just bought. She showed a pair of skimpy leopard print ones and suddenly asked me what I thought. I blinked and sat there mouth working like a fish, no words coming out and she said "What?? try em on for you later?? Ok then." She and my brother laughed, I just flushed red. Which made it all the funnier to them.
Around the age of sixteen, my brother and his wife started having some marital problems. My brother was cheating and he wasn't trying very hard to hide the fact. At the time, they both lived in the guest house behind our parents house and one night around 1 a.m. I noticed my sister-in-law standing on the porch alone, smoking. Then she went back inside. I pulled on my jeans and walked out the backdoor (my "bedroom" was the back porch) and knocked. When she answered I asked was everything ok. She smiled. Yeah, sure. My brother was off screwing around again, but she really didn't care anymore. I stood there, and looked at her. I was horny as hell. I wanted her. But she was my brothers wife and so I pushed the desire away and went back to bed.
A pregnancy and a new baby fixed their marriage short term, but eventually they divorced and my sister-in-law moved away. I was in college at the time and figured, well that's that. You'll never get a chance now. I let it go. A few years came and went and my brother passed away. I started caring for my nephew and by 2012, I was twenty-six and my nephew was eight. While out at the park on afternoon, my former sister-in-law, my nephew's mother came walking up "hey there!"
She had been living in Washington state and working as a nurse in a long term care facility and hadn't heard of my brother's death. She asked if she could visit and get acquainted with her son. I said absolutely, so we exchanged numbers and addresses.
She began spending as much time with me as with her son, often arriving at my place hours before my nephew got home from school. She'd lost her job in Washington, she told me and now she was having some pretty rough times. She was staying with relatives, but they were all potheads and drinkers and she was getting sick of the constant partying and filthy house. Well, I said, you can stay here. I know your son would love it.
Almost as soon as she moved in, we started having sex. The second night she was there, we ended up in bed together. We didn't have to speak about it really. The desire was just there, had always been. We were just finally acknowledging it.
We've kept our sexual relationship as behind closed doors as possible. But my nephew is growing up fast. We can't hide it forever. And so, I've decided to end it. I think I'm in love with his mother, but it just wouldn't be right for me to pursue this. It'd mess the kids head up and I need to do right by him.
