Sleeping with my wifes sister
I've been fucking my wife's sister for 2 years now. I fucked her twice before getting married. We would always still flirt with each other, but nothing would happen more than just touching and teasing. Wife makes comments about her sister getting me turned on. Her sister is married too. A few years ago her sister started coming over and would stay at our house for couple hours to do remote work while she waited for her kids to finish sports practice which was close to our house instead of going all the back home. My wife suggested she just come over and work from here. I work remote too, but my wife has to go into the office. Her sister comes over 2 to 3 times a week. At the beginning we just would be in separate rooms doing our work. Now we work in the same room. About 2 1/2 years ago she was having problems with her husband. We would talk a lot about the challenges we were both going through. Then 2 years ago I was asked to lead a team in India for 1 month so was working nights and sleeping during the day. Her sister was still coming over, but I would be in bed. One day her sister came up and knocked on the bedroom door and said she needed to talk. Her sister came into the bedroom and sat on the bed. She was sharing some challenges going on with her husband and one point said thank you, and then wrapped her arms around me. i looked at her and then she leaned in and kissed me. We kept kissing and felt her hand go in my shorts and start rubbing my dick. I slid my hand under her shirt and pushed up her bra and started rubbing her chest and nipples. Her sister pulled off my shorts and continued rubbing. I took off her shirt and bra and continued kissing and rubbing. I slid my hand into the yoga pants and her pussy was so wet. Her sister wasn't wearing any panties. I fingered her and she took off my shirt. I pulled off her pants and started eating her pussy. Her pussy was so wet it was dripping down to her ass and onto the bed. I was licking it up and worked my way back up suck her nipples and kiss her. I felt her grab my dick and rub it on her pussy. Then she put it inside her. It felt amazing and she let out a moan and we fucked. I made her cum and as I said I'm cumming she wrapped her legs around me to keep me from pulling out. I came inside her and felt so good. We kissed more and I fingered her pussy again and she came again. We looked at the time and she had to pickup the kids in 5 minutes so she got dressed and left. We have continued this consistently 1 to 2 times almost every week since. We are both are still happily married, but enjoy this time with each other to talk and play with each other.
