So the wife and I go to Vegas for a weekend with a friend and her boyfriend and stay at a buddies house that was out of town so we had two bedrooms. The gf of the couple we went with had slept with the wife and I prior to her officially dating the other guy. They had an open relationship so we knew it was going to be fun. Wife and I are in the lifestyle but had only full swapped in the same room once before this.

I had been up for almost 24 hours as I drove all of us to the airport, couldn’t sleep on the flight, and then we hit the strip and had drinks etc. Everyone else had slept during the drive etc., so we head back to the house to get cleaned up and we were going to head back out. We start chilling in the living room start and then we start fooling around. The wife and I were playing and I stripped her and the other two were playing on the other end of the couch. I excused myself to use the restroom.

Now I don’t find this out until later, but the other girl got my naked wife to sit down next to them. My wife ends up checking to see if I’m coming and then checks out his cock, which turns out to be huge, and strokes him for a few minutes before I come back in the room. Mind you, we never played in separate rooms and hadn’t had any discussions about it.

So I didn’t know she has already been stroking his huge cock as she had already moved back to where she had been when I come back in the room. I tell her I need to take a nap before we go out so I’m not a zombie so we head to our room and they head to theirs.

My wife is super horny and based on comments they made, knows they are playing in their room. I’m half asleep already and she asks if she can go to their room and I don’t even think about it and say sure just wanting to get some sleep.

So off she goes completely naked and horny to their room and I start dozing off. She comes back in a little while later and wakes me up and and whispers that they want her to “sit on his cock”. I asked her if she wanted to and she said “Kinda” and seemed out of breath. I say go for it and she asks how far she can go. I tell her “Go have fun.” as I simply wanted to go back to sleep, not thinking that I just gave her permission to do whatever she’s wanted with no limits.

So she basically runs out of our room to theirs. I lay there and dozed off for a while and then it hits me what I just did and it woke me up with a gut wrench. Like fuckkkk. What did I just tell her to do?! But didn’t want to go in and look like a bitch and tell her to leave after I already gave her permission. So laid there with everything running through my head.

So finally I get up trying to decide whether I should go in or not. A few minutes later his gf comes in and invites me into their room. I walk into the dimly lit room to see my slutty wife on her hands and knees slurping and sucking on his huge semi hard cock and massive balls. I noticed a large wet spot on the sheet under her pussy but didn’t think much of it in the moment.

I dove in and ate her pussy out from the back as she noisily sucked on his cock and balls. Seemed like she was over the top excited as her pussy was extra soaked. I end up fucking her and noticed she seemed a bit loose but chalked it up to how excited she was. Later after we go back to our room I asked her what she did with them. She told me she sucked him and they wanted her to sit on his cock but she didn’t. Later after the trip she changed it to not sure if she had and said she didn’t remember everything they did since she was tipsy.
