How I [M] cheated on my wife [F] with the sister of her best friend

My wife and I were invited to spend a long weekend at a house in a gated resort community. The house was a rental property that belonged to our friend’s father-in-law. The house was huge on a lake in the woods, it was beautiful. Our friend’s sister Leslie met us there. She managed the rental properties for her father-in-law and was going to spend the weekend with us. Leslie was very beautiful. She wasn’t the skinny model type but she had her curves in all the right places. She had dirty blonde hair that was down over her shoulders. It is safe to say that she was the type of woman who immediately stands out.

​

The first night we all sat on the deck talking and telling stories around the fire pit. I always enjoyed sitting by a fire. There is something earthy/primitive and romantic about it. Joining us were our married friends, their parents, and Leslie. Leslie was married, but her husband was not there. I had never met him though but heard he was travelling a lot for work.

​

We eventually headed to bed and I had to stop and use the bathroom as my wife walked down the stairs to our bedroom. As I came out of the bathroom, Leslie walked up to me and told me how was glad she were I could make it. She gave me a quick hug and kiss on the cheek and walked away.

​

As I said, this was a huge house with 3 levels, dens, porches, game rooms, and more. My wife went to bed and I was not ready yet, so I stayed in one of the dens and started to watch TV. About 15 minutes later, Leslie came into the den and sat down next to me on a sofa, asking if there was anything good on. I said something like the movie just started. I can’t remember the movie, but I was just sitting and watching a few minutes when Leslie moved closer to me and put her hand on my thigh. After a few minutes I did the same and she did not push me away. I started to rub her leg and slowly moved my hand down to the crotch of her panties; she was soaking wet. I slowly pushed her panties aside and started to move my fingers in and out. She had her head back and eyes closed enjoying the fingering. It wasn’t long after until she suggested that we retreat to her room.

​

================= HOT STUFF =================

When I checked on my wife, she was deep asleep, so I went to the bedroom where Leslie was in the bed waiting. We kissed passionately and in no time at all we had removed our sleepwear and were gloriously naked under her sheets. Finally, I was able to see her glorious breasts. I went down to kiss them and suckled on her nipple while also running my fingers through her wet slit. I rolled Leslie on her back, climbed on top, and mounted her. She wrapped her legs around me as I pushed my cock deep inside her. She was very wet and tight as she had no children so I really enjoyed the feeling of her pussy. Apparently, Leslie liked it too as she was moaning in my ear that she was about to come and to cum inside her when she orgasmed. I could feel her urge to orgasm and I sunk in deep, unloading rope after rope of my hot, thick cum inside her. I stayed inside her until I got soft, slipped out, and rolled off of her and onto my side.

​

After a few minutes, Leslie said thank you, that was wonderful. She said we could talk more tomorrow but that I should get back to my wife. I went back to our bedroom and climbed into bed next to my wife.

​

The next day, Leslie met me outside as I was getting ready to go for a hike by myself. She said that she really enjoyed last night and asked if I would like to meet her at one of the rental properties she managed later in the day. She knew that I had asked her for a pass for the Fitness Center nearby she belonged to. I normally work out almost every day so it would not appear abnormal to my wife. She gave me the address and location and time to meet her there. About 2 hours later, I got into my gym clothes and told everyone I was heading to the gym. Leslie had left about 15 minute earlier. When I got to the house at the address that Leslie gave me I walked to the front door and found it open and Leslie was sitting in the great room drinking a bottle of water. I walked over to her and took her into my arms to kiss her. She hugged me and kissed me back. She said that she wanted me again, but that we needed to talk. We sat down and proceeded to tell me that she was about to leave her husband and that her only concern was that she did not want to break up my marriage. I assured her that I understood and appreciated it.

​

She then leaned over, kissed me, and took my hand leading me to a bedroom. She told me to get into bed and she did a slow striptease removing her top, shorts, bra, and panties. In the full daylight, she was a goddess; full breasts, rounded hips, and a flat stomach. She had a little blond landing strip above her slit, my favorite. She told me that she wanted to enjoy this and to lay down and let her take charge, I said yes Ma’am. She climbed into the bed reached over and took my semi-hard cock in her hand, leaned over and took the mushroom head into hear mouth. It felt great as she sucked on my tip using her tongue and cupping and massaging my balls. As she was sucking on me I was running my fingers through her puffy wet lips. When I was fully hard and ready Leslie climbed up put her leg over me, reached for my cock and rubbed it up and down her lips.

​

When I was lubricated with her wetness she proceeded to slide all the way down until she bottomed out. After a few moments, she started to ride up and down on my cock, she would bottom out and grind her pubic bone against mine. It felt great and it took all my control not too cum too soon. Her beautiful breasts were dangling in my face so I took the opportunity to take turns sucking on each one. As we were alone this time, she was much more vocal with moaning and telling me how good it felt. I could tell she was getting close by her breathing and that her moans where more frequent, suddenly she tensed up and told me she was cumming, I grabbed her bottom and pulled her to me and shot my huge load as deep inside her as I possibly could. Eventually, she collapsed on my and we staid like this for quite some time.

​

After some more cuddling and kissing, she said that I better get going to the gym, so we exchanged one last kissed, got dressed, and went on our way. Later that day she send me a message saying and that she did not regret our coupling at all and if we ever had the opportunity to meet up again, she would love to.
