My Bf an I recently had his best friend and gf move in with us about 4 months ago. They were having hard times paying bills due to him loosing his job. They stay in the other bedroom and at first, they kept to themselves.

After a few weeks, My bf and I would be in the living room watching TV while they stayed mostly in the bedroom. One nite after we went to bed and I had fallen asleep. I was awakened I could hear the faint sounds of heavy breathing. I needed to use the bathroom so I walked down the hall to use the restroom and as I walked by the bedroom and the door was shut. I could plainly hear them having sex. I went into the restroom across from their room and sat on the toilet. I soon found myself with my panties down rubbing myself to the sound of them giving each other pleasure. I quietly, lay down on the floor in front of the bedroom while listening to them under the crack in the bottom door. I could really hear them good as I could hear him penetrating her and could hear the sound of her sloppy wet pussy. My heart was racing, and I found myself laying there on the floor with my panties off and feeling so good as I rubbed to the pleasant sound. After just 3 or 4 minuets, I finished myself off, pulled my panties up and went back to bed. I lay there for a few minutes and thought about how nasty and dirty for doing such an immoral thing.
