Sisters or brothers

My ex-wife's sister, yes. I went to her house one day to help her move some stuff around. Wife was OK with it, in fact she volunteered me to help her sister with the job. It was some distance to travel and I ended up staying the night and having sex with her. If I have to give a score I'd say wife was better because we knew each others ways. I suspect my wife knew about the sex with her sister because when I got home she asked me if I had enjoyed the visit with a big grin on her face!

No but I fucked my brother's wife and he has fucked mine. We both agree that my wife is the better fuck.

I fucked my girlfriend's sister one night after we came from a party. My girlfriend was drunk and she wanted to get out right in front of the house before I found a place to park. Her sister was still in the car in the front seat next to me. As we watched her stagger up to the front door and open it, her sister looked at me and said, "let's get a room". I took her to a nearby motel and fucked the crap out of her. I'd always wanted to fuck her anyway and she knew it.

There was another time when I fucked this really cute chick that I secretly liked. I gave her some money after we got through. A day or so later Her mother paid me a visit and asked me if I would fuck her for money. I fucked her mother too. They both were good, but mom was better.

Accidental sex with wife’s sister. We were at our vacation home, two bedrooms. My wife and her sister are ten years apart, my wife was 32 and her sister was 22 at the time, three years ago now. We had been drinking a lot at the beach and bar after, and when we came home they sat on the sofa and were drinking more. I was with them for a while, told my wife in private that I wanted sex, she agreed so I was expecting some. It was about 3 am, and I went outside for a smoke, and was on my phone for a while. When I came back from my angle the girls were out of the living room so I went to the bedroom and got into bed and started feeling up my wife beneath her dress, and said “let’s have sex” she moaned and stuck her butt out as I felt it up, so I pulled her panties down and took her hand and she was rubbing me to get hard, and I slipped it in and it felt different. Her butt felt different, her boobs felt different, and not even one minute went by before I realized it. She was on her side and I was behind her in my side, and she was pushing back and doing me. I knew it felt different and it felt so hot I kept going and it didn’t last long. Maybe 5 minutes and I came on her butt. I got towels to dry her off and put her panties back on. I went to the other bedroom and it was empty. I went to the sofa and my wife was passed out there, I didn’t see her from behind the sofa and her sister must have went into our bed by mistake. I laid down on the sofa with her and roused her, and had sex with her. I felt so much shame and needed to make love with her. In the morning I was so worried but her sister woke up with a huge hang over and never mentioned it.

Before we met:
BF of my wife's sister volunteered to help my wife carry stuff back to her apt. Feeling down after a big break-up, my wife let him fuck her standing up in her kitchen. Wife said they went back to sister's party - "smelling like sex, and feeling a little guilty". Not too guilty - later, he hid his car came back- she let him in and he fucked her again in her bed!

I'm sure my wife was the best fuck of the two sisters!

In college I was fucking my gf's sister for two years behind her and the sister's bf's back. We were completely incompatible but she's still the best I've ever had in the sack. 5'4" blonde hair blue eyes with perfect tits and ass. We'd get into heated arguments over dinner with the family and then fuck so rough that same night when everyone was asleep.

My wife cousin sat next to me a picnic. she was feeling my leg up under the tablecloth. With 3 beers she was feeling my hard dick over my shorts, while continuing normal conversation with others. When the others left to play games I felt up her bare leg, went under her wet thong and fingered her pussy till she came.

Incest is nasty

I never did. But our older brother would parade his girlfriend naked around me and my other brother. I'll never forget
