I live with a Bf/Gf couple and share an apartment with them. I have my own bedroom and the other night I went to the store to get a few things and was gone about an hour or so. I stopped by a fast food restaurant and picked up something to eat and headed home. When I got home, I lay on the couch and dosed off to sleep with the TV on. I was awakened by the sound of my roommates making noise. I laid there for a moment and could hear the bed squeaking and the sound of heavy breathing. It was then obvious that they were getting into it pretty heavy. I then got up and walked down the hall closer to the bedroom and noticed the door was not fully closed. I peeped into the room and noticed he was on top of her and all I could see was his ass and her legs wrapped around his back. As I stood their and seeing them getting off, I did something that now I feel ashamed of. I actually got so wrapped up in watching them. I found myself using my hands to pleasure myself and then could not help but to pull my panties down to my knees as I continued watching through the crack in the door. I was so wrapped up watching and listening as I cranked up the speed of my fingers as I rubbed my clit. I was feeling so dirty and nasty getting off to watching them pleasure each other. After only standing there for about 10 minutes I could feel I was getting ready to cum. I took a couple of steps back and put my back to the wall and finished myself off as I listened to them. I pulled my panties back up and slowly walked back into the living room as if nothing happened. As I sat there, I really began to feel trashy,ashamed and dirty, that i had done something wrong. Now I look back on what I did and it causes me to regret what i did. I wanted to tell them because of my conscience, But it is just way to embarrassing for me. I'm really sorry for what I did and have learned what not to do from now on. I have committed a really bad sin and I cannot express how bad this makes me feel.

Please do not think bad of me, But, I felt like confessing this to vent my feelings!
