[MF] brief encounter with wife’s sister (long)

Ok, this is the “in the light of day” kind of post. Last night my wife and I went out with her sister and husband. There was a local event at a bar we like; they had a huge tent set up in the parking lot, had to park a mile away, but great band, great booze, great time. We’ve done this kind of thing before as a foursome, so I expected the norm. I was so wrong.

I should add a little info to paint the picture. My wife and I have been married for 14 years and have an open marriage, while we try and keep it a secret, I think most people close to us have figured it out. My wife and her sister are fraternal twins and they’re nothing alike. Wife is 5’9, blonde, curvy and a very free spirit. While her sister is 5’0, brunette, petite and generally has a permanent stick up her ass. I love to give her a hard time and, despite her short fuse, I’m one of the only people that can poke fun at her without being blacklisted, which is fun.

Back to last night. We were well into the night and all well lubricated. The band was playing all the hit from our “younger days” and we were all into this party. By this point the crowd was generally in the same condition as us and had grown to be pretty congested tent. Packed in like drunken, ear-ringing sardines. Wife at my side singing and dancing and, because of her short height, sister was in front of me, next to her husband. Essentially, her ass was rubbing on my thigh all night long. At one point she turned to me and, while singing, gave me the sexiest smile I’d ever seen on her face and she pushed her ass back into with obvious intent.

My mind raced for a minute as I was putting it all together and instantly became hard as a rock! A moment or two later she pushed back into me and my newly developed erection. She turned and smiled again and I felt a hand on my crotch! I quickly looked over at my wife and hubby in front of her. With the crowd, the lights and the music, there was no way anyone would’ve seen that, or could notice her continue to do that for the next couple of songs. I occasionally reciprocated by caressing her tight little ass and reaching around to rub her perky little tits under her t-shirt. It was dangerous, but extremely fun.

This went on for the remainder of the night, until the band wrapped up around midnight. The crowd drifted apart and most went home. We decided to not rush home and continue the night back in the bar, which was also packed with the concert goers. We got a table and ordered a round of drinks and some appetizers. Sister was sitting across from me now, giving me the fuck-me eyes and rubbing her foot up and down my legs. Clearly, the fun wasn’t over.

After ordering a second round, sister mentioned that she was getting heartburn and asked if anyone had tums, etc.. Everyone knows that I suffer from acid reflux and am never far away from antacid, so I mention that I have tums in our car. Perfectly, my wife suggested that I take her sister out to our car to address the situation. We head outside and she is instantly grabs my cock again through my jeans as we’re walking, and start making demands about what she wants me to do to her and how long its been since she had cock, etc. Once we reach the car she pushes my against the car and guides my hand into the waistband of her jeans down to her soaking wet pussy. I was just as shaved and tight as I had hoped for. As we stood by the car, we kissed, fondled and I rubbed and fingered her clit. She had her hand down my pants and was stroking my cock in my jeans. I turned her around and pressed her chest against the car and continued to squeeze her firm tits and pinch her hard nipples under her shirt. Soon, she was bucking back into and flooding cum all over my hand. She opened the driver’s door, turned, sat down and undid my jeans, finally freeing my painfully hard dick. She proceeded to suck harder and with more passion than I’ve ever experienced. She guided my hand to the back of her head, so I grabbed her ponytail and fucked her sloppy, spit and tear covered face. I pulled back to give her a breath and she angrily yelled at me “cum down my fucking slut throat”! I’ll never forget that moment. She quickly returned to swallowing my hard cock. About two minutes later, I exploded, filling her throat and mouth. She swallowed what she could, but a lot of it leaked down her chin and neck. She stood up and slapped me hard across the face, smiled that sexy smile again and said “I’m not done with you”!

We cleaned up as best as we could and headed back in, all in all, we were only gone about ten minutes. The rest of the night was kind of cloudy, but I clearly remember her sitting across the table from me with little cumstains around the neck of her t-shirt. Not really sure what to expect next, but I’m eager to find out!
