Ever ask yourself the question.."Can the kids hear us getting busy?" Well..
I think most us who grew up in a 2 "adult" (Damn...can't say parents and cover everybody and that's a damn shame) clearly knew what was going down and when it was going down. For me it was when both doors to the bedroom and master bath were closed and locked. Also the TV was exceptionally loud so it was a dead giveaway to me and my brothers. Just don't think you slick as the above video will show you that you are not as smooth as you may think. They can hear you!! LOL!
