My wife and I spent the weekend with another couple and had an accidental night time mix-up.

Last year, my wife, Lily, and I were invited by another couple to stay in their family cabin in rural Michigan. The couple, Alice and Robert, had their first child about 18 months prior and were taking their first vacation since. Lily and I were in the same boat at 15 months, and desperately needed some time away to recharge.

The vacation was fairly standard as far as cabin trips go. We swam in the small lake that the cabin sat on, grilled food out on the deck, and played some drinking games off of a makeshift saw horse/plywood table. It's important to note that neither couple had been drinking much for the past few years, especially the moms since they both had primarily breastfed. The drinks were hitting harder than usual, but we kept foolishly drinking like we were back in college.

Somewhere along the line of the night, Robert broke out some edible gummies and offered them to everyone. Considering how drunk everyone was, we should've said no, but we were still in party mode. We threw our gummies back and went back to playing more drinking games. Roughly two hours later, the high started to kick in. I rode it the best I could, but the combination of the gummy and whiskey put me on my ass.

I must have faded out because I awoke hours later in bed next to Lily. It must have been late because it was dark, like pitch black can't-see-an-inch-in-front-of-your-face dark, and everyone in the house appeared to be asleep. My head was still spinning from the edible and I had to piss badly. Before I could get up to go to the bathroom, I heard someone stumbling their way down the hall towards the kitchen. It must be Robert, I thought. I don't remember him eating too much throughout the night so he's probably trying to get something on his stomach. I got up to use the bathroom, but couldn't find my phone for a light source. I blindly made my way down the hall the same way that Robert went because I knew there was a bathroom in that direction. I finally made it to my destination, but had to take my time because my head was swimming. I finally finished up and made my way back down the hall towards the bedrooms.

I was still pretty unfamiliar with the layout of the house, but I got to the room that I thought I came from. When I reached the door, I heard rustling coming from the bed and the sounds of kissing. I quickly backed out, realizing that I accidentally went to Alice and Robert's room! As I walked away, I realized that hearing them fool around in such close proximity had turned me on and I decided to take that energy back to my own room.

I finally found the room, fully stripped down, and climbed back into bed where I began spooning Lily. I wonder if she heard the other couple going at it, too, because she immediately reached back and grabbed my hard dick, though I don't think she expected me to be naked already! I reached around and started rubbing her through her panties, realizing that she was already starting to soak through them. I pulled her panties down and blindly guided my dick inside of her, going slowly at first. After a bit of warm up, I started going faster and deeper. I lifted her shirt and took her breasts in my hands, gently pinching her nipples between my fingers. Since I was still positioned behind her, she craned her neck back to kiss me. I could taste the tequila and faint blue raspberry from the gummy on her tongue. At this point, I realized that we could hear the other couple fucking in the room next to us and it made us more aggressive in our own love making.

Since it had been a week or so since we last had sex/I masturbated, I could feel an immense orgasm coming on. I decided to switch positions to delay this and we moved to missionary. We kept a good pace in this position until a few minutes in when Lily put her mouth to my ear and said, "keep going like that, I'm going to cum!"

Wait.

That's not Lily.

My clouded mind quickly began sobering up and I realized that I was fucking Alice, not Lily. Unfortunately for me, I didn't realize it in time because the mixture of the surprise and the hot breath in my ear sent me into the biggest orgasm I have ever had. I filled Alice with a week's worth of pent up sperm, which overflowed onto the mattress. Alice was riding her orgasm out while my mind raced on what to do next. At this point, I also remembered that Alice and Robert were trying for another kid and she was likely not on any form of birth control. Once she had finished, I sheepishly said, "Alice, I'm so, so sorry; it's me."

Alice made a jerking movement for the nightstand light and yelled under her breath, "WHAT THE FUCK?!" For a short moment, we were both silent, staring at each other. And just like that, the silence was broken by a moan from the other room. We both laid back, shaken by confusion and disbelief. I'm not sure what was worse: hearing my wife getting the same experience on the other side of the wall or the thought that I just inadvertently became a potential donor for our friends' next child.
