Jes and I had a couple, about 25 years old who lived below us in an apartment we had a couple years back. While we do fuck quite a lot, we aren't exactly the type to have three hour screaming marathon sex on a daily or even weekly basis.. lots of foreplay is more our thing.
Anywho, I got a call at my desk at work one day, back when I worked in a cubicle for an engineering firm - where I sat smack dab in the middle of the office. It was the property manager ("pock faced bitch" I call her)who called to inform me that there was a problem that she couldn't discuss over the phone so she needed me to come to her office after work. I explained to her that I would not attend a meeting, for anybody, without being given a reason for wanting to attend said meeting. She eventually realized she would have no choice but to tell me what was going on, and proceeded to tell me that one of the neighbors called and explained to her that she heard "very loud intimate noises" coming from our bedroom.
I tried to maintain my composure being that I was in my cubicle, but I just simply could not refrain from busting out laughing hysterically at this woman. I then proceeded to inform her that I was in no way shape or form responsible for the noises produced by Jes while I was deep inside of her, and that I would under no circumstances do anything to reprimand the situation. I also told her that the neighbors might not care so much if somebody would come into my unit and fix the noisy ass floor under my bed.
Being that I was very upset with the situation, I came home that day and proceeded to make some very loud intimate noises of my own in the hallway outside my lovely neighbor's door.
Moral of the story here I suppose is that if you like to fuck, you had better have enough money to afford a house, or at least a very high quality ball gag, but even that won't shut up your noisy floor or nosey neighbors who can't get a good lay.
