[MF] [MF] I heard my sister having sex in the other room, and it turned me on

I’ll try to make a long story short. My wife and I decided to have a very small gettogether at our condo on New Year’s Eve. We only invited two people: my sister and a friend of mine from work. Both had been COVID tested very recently, and we specifically chose them because my sister is single and lives alone, and we didn’t want her to be alone. And my friend is also single and lives alone, and he has some on-and-off issues with depression and anxiety; nothing too severe, but I feel bad for him because he’s a really nice, humble guy. He’s the shy introvert type, so I thought it would be good for him to have a fun night over at our place without too many people to make him anxious.

The night turned out to be a blast. We were all drinking pretty heavily, watching movies at first, then socializing and playing cards and listening to music, stuff like that. Everybody was enjoying each other’s company. The drinks were still flowing after midnight, and my friend was coming out of his shell. My wife and I both noticed an hour or two prior that there was chemistry building between him and my sister, and it was getting more and more obvious. A little later on at around 1:00 a.m., my sister approached my wife privately and said something about how she was pretty sure something might happen between her and our friend that night, and my wife wasn’t really surprised at all because she saw it unfolding a few hours prior.

My wife suggested that they should just stay at our place because they’d both had too many drinks to drive, and it was 5 F that night where we live, and she would feel guilty having them take a taxi. My wife then approached me privately and asked if it would be ok if they stayed overnight and asked me if it would creep me out if they did, because there was a pretty good chance at that point that they would end up having sex. I was pretty damn tipsy at that point, and at the time the thought actually didn’t really bother me, so I said it would be okay. I didn’t want to send them out into the cold night either.

Our condo isn’t terribly big, and the spare/guest bedroom we have is right beside ours. So about 5 minutes after we all crashed, sure enough, the playful noises started coming through the wall. Then within about 10 minutes it was full on sex; bed springs and moaning and the whole production. I don’t know why, but I started getting that really excited naughty butterflies feeling in my stomach, like that feeling you get when something is erotic but weird/naughty at the same time. That’s the best way I can describe it. And I could tell it was getting my wife a bit riled up too. So we ended up having sex while we could hear them at the same time, and it was so weird but hot at the same time.

I feel absolutely no attraction towards my sister at all and have never had a sexual thought about her, but I still wonder if I’m some kind of a sick freak or perv. My wife assures me that I’m not and feels that the only reason it excited us both is because it was so naughty and taboo and out of the ordinary. I think she’s totally right, but part of me still feels guilty.

They are still casually dating and both seem pretty happy about that, so that’s pretty cool. I just hope remembering that night doesn’t make either of them too awkward if they become more serious lol.

  1. Not creepy at all though I wouldn’t want to hear my sister having sex in the bedroom next to mine either. I think your feelings are completely healthy though

  2. I think it’s fine. You even had sex with your wife because you both got off on the naughtiness. It doesn’t seem to have awakened some incest fantasy in you, so its just a fun anecdote between the two of you.

  3. Concur. Those sounds are designed by nature to make you want to engage in that same activity.
