We never had sex in front of anyone. Unless you count the time we were doing it in the front seat of his mother's car, in her church parking lot (I assume there were people somewhere that saw), or the time his roommate walked in on us, or when were were on the beach in Biloxi, MS.
We've done this a few times as it is a huge turn on to be watched. But was it your closest friends, roommates, another couple, or just a large group of people?
Like a few of the folks who have replied my husband and I have gone to a few swinger parties and events. As such, we have had sex in front of... from a few folks to an entire room full (20??? +/-) we were to busy to count. Probably the coolest and most planned expose we had was at a place called Sea Mountain Resort in Palm Springs, CA. Its a swinger type place with indoor and outdoor play that markets as a nude resort during the week. We went there for the first time and when you check in you check in with a totally naked hostess chick who cruises around all day in nothing! Super cool job!!! So we are laying out by the pool and notice some other couples being a little frisky but nothing super crazy going on... One couple who is in an open air upstairs room is for sure diddling each other but a few folks are just laying out reading books and stuff to. So my husband starts in touching me and before you know it I'm getting doggy-styles along the side of the pool with just about everyone watching. One lady has put down her book and seems to just be enjoying the show... the naked hostess girl actually walks over and offers me a bottle of water because i look like i am getting hot in the sun! I finish by riding on top of him and take a full on internal creampie in front of all these people who just go back to whatever they were doing before it started without even blinking an eye. Before we left I sucked him off along the side of the spa and then he ate me in the locker room before we got dressed to leave! Awesome awesome place!!! XOX CreamySweet
Two people. When I was younger, an old girlfriend and I had sex in front of her best friend and her boyfriend, then we switched partners. I've been watched by friends of girlfriends in the past, but that was only one person each time.
