[MF] I’ve been sleeping with my wife’s sister for a month.

First off, a little background. My wife is 32yo and from Japan. She grew up in a conservative family and has two sisters with the one in question now being 27. We met here in the states but got married and spent most of our married life in Japan. She has always had a low libido and was not really interested in trying new things. I didn’t care at the time as I was madly in love and thought it wouldn’t be an issue. We talked and things got better and we were having plenty of sex (2-3times a week) for me. However, our first son was born right before we moved back to the states and things dropped off. We went to having sex once a week to every other week. It was a struggle for me. I tried everything. Talked with her. Paid a lot of attention to her and tried things like challenges to try and spice things up. I was a former Air Force officer and was very fit when we married. I’ve mostly maintained that level of fitness as I’ve entered law enforcement so it’s not like I let myself go and she lost interest. We talked and talked and she thinks it’s depression and stress from work. I became a frequent visitor to r/deadbeadrooms.

Fast forward a couple years and her youngest sister came to stay with us for period on a work visa. She is near identical to my wife despite being nearly 5 years apart. However, she has extremely large breasts which is very unusual for being Japanese and I have fantasized about her before. Although, it’s something I’ve never seriously considered.

Now to how it all started. As of a month ago, the sister has been here for 6 months. I was hanging with some friends and we were all drinking at our house. The sister was drinking with us and was very flirtatious with a couple of my friends and despite her attractiveness none would bite. They are all married. One of them actually mentioned he won’t be coming over to my place to drink like that while she is here because he almost took the dive. I probably would have stopped him as that could have cost him his job quick.

Later that night it was just us three and she mentioned in Japanese how horny she was and that she hasn’t been laid she has gotten here. She was really disappointed she wasn’t able to fuck any of the guys that were there. I was taken aback by the fact she said that in front of me but I started to fantasize again and got extremely hard. My wife noticed and grabbed a hold of my dick through my pants.

We retired to our rooms. I tried to initiate and went straight to eating her out but she stopped and said she was not feeling well from the alcohol and wanted to go to bed. This was like a punch in the gut. I was hard and could barely contain it. This feeling of rejection turned into drunken anger. I exclaimed that well if she wouldn’t fuck me maybe her sister would. It was a terrible thing to say and I regret it to this day as her LL is definitely not her fault. What she said next shocked me. She sat up and with all seriousness told me to go ahead. She said she felt really bad and wanted me to be happy. In my normal state I would have taken this hard and would have dropped it but I was still in my drunken state. I stormed out to the sister’s room and opened the door without knocking. She was standing next to the dresser in just a bra and underwear looking at her phone. She looked up in surprise but didn’t try to cover up at all despite my intrusion. I walked over behind her and started to kiss her on her neck. It was like fireworks when off inside of her. She gasped and started to tremble a little. I walked her over to the bed and sat her on the edge and moved her panties to the side and went straight to town. Normally I’m big into forplay and teasing but the andrenline and excitement gave me severe tunnel vision. She began to moan and started to do that slight wimper you her in Japanese porn. My wife doesn’t do it and I’m not a big fan of it but in the moment it was hot as fuck. I picked her up and laid her down fully on the bed. I kind of paused and admired her chest then reached around and undid her bra. These tits were probably the most perfect I have ever seen. I slowly began to lick and suck on them while undoing my pants. I slid my cock slowly into her pussy as she cried out that it was too big. Honestly I’m not that large at 6 inches with a thicker girth but that’s considered fairly big in japan and she wasn’t used to it. I took it slow for about a minute and could no longer contain myself. I started to pound her so hard the bed was knocking into the wall. She came very fast but it took me a few minutes because of the alcohol. I was about to cum and reached for the towel she was using for her hair as I didn’t want to cum inside of her. To my surprise she slid from under me and took my dick her hand and started sucking the fuck out of it. She took my load in her mouth and immediately swallowed it. I sat there in disbelief. I always came in my girlfriends mouth when I was in college and loved it but my wife hates the taste. It felt like a dream. I stumbled back to my room and laid down in bed and fell asleep.

I’ll add additional posts with specific encounters and my wife’s reaction after that night. This post was too tedious on mobile.
