I [M] [f]ucked my SIL at my in-laws’ house

My wife (at the time) and I attended an event for a close friend of her family, and most of the family was there—her parents, 2 brothers, 2 sisters, and all of their spouses. The event was at a big open hall, and there were probably 100 people there.

I had met this particular SIL several times (she was my BIL’s wife) but didn’t know her well. We got along just fine, and no tension good or bad existed between us. In other words, a pretty normal unremarkable relationship between in-laws. Until that event.

On a few occasions, we found ourselves standing next to each other, just the two of us, kind of watching the goings-on. My ex’s family is rather…dynamic…and we were “outsiders” being that we had both married into it. We mostly made comments to each other, chuckling about this or that crazy sister. But there were a few moments in the silence between where there was the presence of….something. A connection, definitely, being married into this crazy family.

My SIL was about 10 years younger than me, quite short, with dirty blonde hair, a cute but plain face, and a curvy body with great tits. That day she was wearing a tasteful dress that came down a little past her mid-thigh and showed off her curves without showing a lot of skin, just enough cleavage for you to know she had a bangin’ rack, and low heels that gave her short legs a little shape.

After the event the family all headed back to my wife’s parents’ place for the after-party…they lived in a beautiful old Victorian in San Francisco that had been 2 separate units (1st and 2nd floors) when they bought it. They used the downstairs for their offices and lived upstairs, where we all gathered after the party for more food and drink. Places to sit were scarce, and pretty quickly SIL and I ended up next to each other on the far end of the sofa. This is when things started to take an interesting turn…

As the wine continued to flow, SIL moved ever closer to me, to the extent that our entire thighs were touching and I could feel her amazing tit on my arm. Since it was so crowded, nobody really thought anything of us being basically on top of each other. At one point, she got up to use the bathroom and when she came back, I didn’t move my hand from the sofa cushion quickly enough and she plopped her firm, full ass right on it. As I twisted my hand to start to pull it out, she realized it was there and pushed her ass over and down into it…so I left it there and began to slowly squeeze her ass… I looked at her and said “Comfy?” She looked right through me and said “I’m great…”

We continued to sit super-close together, legs touching, her tits on my arm, me kneading her ass, as she very slightly rocked her body into my hand. My FIL came out of the kitchen and looked at us, and said “[Me] and [SIL], make yourself useful—go down to the basement and pick out a few more bottles of wine.”

We immediately got up and tried to calmly walk down the stairs to the front door, but it probably looked like we were sprinting. To get to the basement, we had to exit the house entirely, go back in through the garage (which is below the 1st floor), and through the garage to the wine cellar. As soon as the garage doors were closed, her mouth was on mine and her hand was stroking my cock through my pants. I reached into her dress and bra and got her beautiful tits out, and we made out and I sucked her nipple for a minute before we made our way through the garage to the wine cellar.

Once we were there, she leaned forward on a table and pulled the bottom of her dress up over her waist…I unzipped and pull my throbbing cock out, pulled her panties to the side, and slid in to the hilt on the first stroke (her pussy was drenched). I pounded her from behind while I pulled on her tits and tweaked her nipples, and fucked her through a quick orgasm before I dumped a huge load deep inside her. I was probably inside her for no more than 4 minutes total…

I pulled out carefully and grabbed a paper towel for the mess…she wiped up what she could, then pulled her panties back over her pussy with the paper towel in between and re-situated her gorgeous full tits back into her dress and bra. We grabbed a few random bottles of wine and headed back upstairs, where she went to the bathroom before rejoining me on the sofa—right back on top of my hand…

We were able to hook up one more time, after my ex and I moved back east and she and BIL came to visit. We were able to take lots more time that time (we sent wife and BIL out to lunch just the two of them for a couple hours)…my ex and I split up a few months after that and I haven’t seen SIL since. But I still have those amazing memories…

  1. Did the event motivate the separation or something else entirely

  2. Great story. I can’t wait to hear about encounter #2… if you’re so inclined.
