Sister-in-law [MF]

It’s not what you think.

This is a fresh one though, just happened a couple weekends ago. My wife and I went to a family wedding and afterwards some people went back to her parents house for a little after party. Nothing crazy, just a lot of wine and some other refreshments. It was my wife, myself, her parents, a high school friend of her dad (James), his wife, my wife’s sister (Amy) and her brother as well. My wife is the middle child.

About my wife’s sister Amy. I wish I could share a pic. She is one of the most gorgeous 36 year olds you’ve ever laid eyes on. Very healthy, very fit, just an amazing body with a face that matches. Tight is the best way to describe her probably.

We were all just hanging out and drinking and having a good time. Eventually things started to wind down and the booze really kicked in because I started to fall asleep. I think some other people had already gone to bed by that point to but I’m not sure because it’s all a little hazy. We went up to the spare room and I passed out as soon as my head hit the pillow. It’s a 3 bedroom house with an office and a bonus room. Her parents have their room obviously, my wife and I were in a room, James and his wife were in a room, my wife’s brother was in the bonus room and her sister was on the couch downstairs. That was the sleeping arrangement as I understood it.

So I’m sound asleep and then my eyes shoot open. Fuck, I gotta piss. I just went straight to bed after all that drinking and didn’t pee first and it caught up with me. It was 2:30ish in the morning. So I got up and made my way to the bathroom. I was super parched from all the red wine and could tell that I was about to start getting a headache, so I decided that I’d better go downstairs and get a glass of water.

When I got to the top of the stairs I heard what sounded like murmurs or faint human voices. The lights were dim so I knew nobody was awake, I figured the TV was on or something. I started walking down the steps really slow so I didn’t wake anybody up. One of the first things I could see was the TV. It was on but there was no volume on. The next thing I could see was the couch, but nobody was on it. And then I heard a light tapping. It sounded like someone packing a pack of cigarettes or something like that. As I hit the landing where the curve makes a 90 degree turn I saw movement. It was kinda dark, there was some light and the light from the TV but I couldn’t make out what it was. I stood there for a second and let my eyes focus. It was legs with high heels on.

My wife’s parents have a huge ottoman in their living. It’s leather and pretty firm and basically doubles as coffee table. If I had to guess I would say it’s about 4 feet x 4 feet wide. That’s where I could see the feet hanging off of. My initial thought was why is she sleeping on the ottoman and not the couch? And why does she have her heels on still? She wasn’t wearing them after we got back to the house so why would she be wearing them while she’s sleeping? Then I realized it was 2 pairs of legs. What the hell is going on? My drunken half asleep brain was having a really hard time trying to make sense of it all.

I peaked my head around a little more so I could see more of the ottoman, and then I realized what was going on. Amy was laying face down on the ottoman. The dress that she was wearing to the wedding was pulled up above her waist. James was laying on top of her and he was fucking the living hell out of her. The sound I heard wasn’t a pack of cigarettes, it was the sound of James’s pelvis slapping against her ass. The sound I heard was her muffled moans. James is a big guy, like 6’2 or 6’3 I would guess. Amy is not. She’s tiny compared to him. He was on top of her with on hand holding her wrist and the other covering her mouth. And he was going hard.

I couldn’t fucking believe it. First of all, James has to be at least 20 years older than her. He’s married and his wife is asleep in the other room. Amy is also married (her husband didn’t come because he had to work, but nobody really likes him anyways). They’ve known each other all of Amy’s life. The house is full of people. Yet drunk James is banging Amy out like nobody business.

I didn’t know what to do. So I did the only thing I could think of. I stayed hidden, unzipped my pants, and started jacking off. I’ve fantasized about Amy 100 times over the last 10 years. This was absolutely the best thing I could have stumbled upon. I couldn’t believe it. Honestly, I still can’t. It seemed like it went on for an hour but it was probably less than 5 minutes. He only slowed down one time. He moved his hand from her mouth and she let out a gasp with some heavy breathing. I heard him whisper something to her but I couldn’t tell what it was. Then I heard him ask if she was on birth control and she said no. Her husband got a vasectomy So that wasn’t news to me. Then he said something else that I couldn’t hear and she said “anywhere you want” so I have a pretty good idea what he asked. He started fucking her again. This time he slid his hand underneath her and grabbed one of her tits. Her amazing tits. I’m super jealous of that hand.

He repositioned himself and moved up on her back and started going faster again. She immediately started to make noise and the hand went from her tit to her mouth again. I could tell the way he repositioned himself that he was getting a lot deeper because her muffled moans turned more to muffled screams. He got going as fast and as hard as he could. I could feel the house start to vibrate a bit. He was moaning and I could tell he was about to loose it. I was too. She looked like she was taking the biggest dick she’s ever had and she probably was. He took the hand that was on her wrist and put it around her neck. That must have done it for both of us because I could tell he was cumming and he was shooting it deep inside her. I didn’t have anything to cum in, so I just let it fly all over the stairs. They’re carpet so I was hoping nobody would notice but in that moment I didn’t really care. He finally stopped and backed away. She didn’t move. That was about the time I decided I better head back to the bedroom before I get spotted. I tiptoed back up to the room. I laid there for probably 45 minutes thinking about what I just witnessed before I fell asleep.

The next morning when I woke up (with a badass headache because I never got my water) me and the wife headed downstairs for some coffee. No signs of my cum on the stairs that I could tell. Everyone else was already awake except for her brother. Everyone was sitting around drinking coffee talking about the wedding and the night before. I was looking at the two of them to see if there were any exchanged glances but I never even saw them make eye contact. At one point she got up and kinda hobbled a bit. My wife asked if she was ok and she said she’s fine, she just thinks she danced a little too much at the wedding. I couldn’t help but smile. I know exactly why she had trouble walking!

James is my new hero. Getting to be with someone like Amy who is smoking hot and way younger than him is awesome, but the fact that he made her put her heels back on before he fucker her is legendary. I really wish I could have known what happened between the time that I went to bed and the time that I woke up that got them to that scenario, but I guess I’ll have to leave it to my imagination.

And I am so glad I didn’t pee before I went to bed.
