This encounter was in a Vegas parking garage, it may have ended there but it sure didn't start there.

It actually started at my best friends birthday bash he had at some local lounge. I was there with my wife and we were all having a really good time. I was drinking patron which is like an energy drink for me lol. The wife was drinking her vodka and that night was going well. The lounge was closing around 2am and it got pretty dead by that time but we weren't done, I had been flirting and groping my wife all night and it built up so much i couldn't wait. She went to the womens restroom and I was right behind her. I grabbed her inside and pinned her up against the wall and we began makingout and grabbing each others crotch. I'm 6'0 and the wife is 5'2.5 so I'm bending over a little while she is looking up. Now someone was coming in so we stopped and fixed ourselves, the person turned out to be my best friends female cousin.(we'll call the cousin J).Now I've met J a few times and even comforted her at one of my house parties when she was waiting for a ride. She was pretty buzzed standing there and she was acting all flirty asking what we were doing in a teasing manner, so I showed her and pinned my wife again against the wall and picked up where we left off. She said that we were turning her on and she came closer and started touching my wife and I. J began kissing my wife, now J is pretty tall like 5'10 so it was sexy watching her take control of my petite wife. We cut the make out short as we didnt want anyone to catch us as it was mostly my best friends family left in the lounge. We decided to meet follow each other and go to a casino in downtown las vegas.

When we arrived at the parking garage J had jumped into our car so we could smoke a joint I had brought. We smoked and talked with J about how my wife and I are into the swinging lifestyle a bit and how we are both a bit bisexual with the right people. J is getting super horny as she asked if she could watch us make out again. She is in the back seat of the SUV while wife and I are up front so we begin making out and I pull out the wifes breast and J asked is she could kiss her so my wife climbs in the back and starts kissing her. They kiss and suck on each others breast for a bit. J has some very large breast like DDD. I figured she would have some pretty big nipples but she had some very tiny nipples. My wife has C breast and has some very sexy hershey kiss nipples. Mmm. J then asked to watch me fuck my wife right next to her. So my wife leans on J with her back and I slide right in my wife. My wife is getting burried by Js massive tits and it looks super sexy. I then begin to makeout with J sucking on her lips and letting her suck on mine and my tongue, I slip in a breast suck once every few pumps on my wife. J is all worked up and ask if she can get fucked by me and my wife happily agrees so to make it more comfortable we all get out of the car naked so we can put the seats down and have the whole back to play. We climb back in and I go down on J first before we begin. Her pussy is smaller than my wifes with the lips and it looks and feels very fragile in my mouth J is liking it and it kissing my wife. After sucking J for a bit I start kissing my way up her body and I begin to slightly press my cock into her pussy but it goes further down than expected and she said that for girls her size I need to go higher. It was like a short joke on my wife. During this time my wife is starting to feel sleepy from her drinks and she lays down next to us and starts to fall asleep. J and I are still proceeding. I slide in her and it feels very warm and not super tight like my wife but still tight. She tells me how sexy my wife and I are and how she is lucky to get to do this with me. We fuck for a bit but its getting uncomfortable in the back. So we decide for her to come over so I can get the wife to bed She gets out naked and is getting into her car next to ours but I decide to get out naked as well and slide in her from behind when she bent over to lean in her car. I began pounding her hard and thought how kinky this was that I'm fucking this woman in public with my naked wife in the car next to us, I got so damn aroused I started to go deeper and harder. I could feel my balls wanting to burst so I pulled out and unloaded all over her thick ass. We talked about meeting up at our house for more and exchanged numbers. I didnt call her when I got home and we never got a casual encounter again but we keep in touch via FB today.
