Not quite the same room but the night I lost my virginity my best friend was fucking her man in the room right next door to our room. Completely unplanned we both (best friend and I) ended up heading to the bathroom at the same time afterwards ... lots to compare and discuss, especially with it being my first time!
There have been some parties and stuff where people were paired off and doing various things. Nobody was pretending it wasn't happening or trying to hide anything, but there wasn't any real effort to rotate partners or anything, maybe just a little bit of watching.
Location: I am currently in (polk County) central Florida. I currently reside in the city of Lakeland.
I have had same room sex because I accidentally got to waisted. I climbed into the bed with my girlfriend at the time and we really went at it heavy. I was eating her pussy and she kept saying fuck yeah fuck yeah eat this wet pussy. I heard a noise and turned to look and my aunt had a toy in her pussy saying Please eat my pussy next.
When we were younger we had sex with each other with friends in the same room. Tried to be quiet, but each of us knew what the other was doing.
In a few swinging situations we had had sex with other couples in the same room. We have an occasional glimpse at each other, but spend most of our time focused on who we are with. When the first one finishes, we spend more time watching the other.
