being caught in an awkward spot...

I’m new to this forum and wanted to share a painful scenario with you.. Hi, I’m a 21-year-old male who enjoys tying myself up, living together with several friends. Most of the time it’s great fun having them around but not always… Not when I want to tie myself up! The reason is that most of them are unaware of my little secret, Well, one discovered it about a week ago: My friends were all taking exams and I wasn’t, so I was home alone. I felt quite horny because I hadn’t done self bondage for over a month and had been looking forward to it ever since. So when they left the house I started unpacking my “things”. Normally my bondage location is restricted to my own room, but like I said before I was pretty horny and I was planning my self bondage in the bedroom of a girl friend I have a crush on. So I went to her room. There I found her dirty panties near her backpack and decided to tie them around my head and tape my mouth shut. Then I undressed, put the lovely smelling panties on, and tied myself tight to her bed. Because they were gone for most of the morning I decided to use a frozen key as release mechanism. So there I was: Tied to the bed from the girl I liked blinded by her scent forced to smell her panties to be able to breath. I also put my mp3 player on loud punk to prevent me hearing a thing. I like the risk of someone coming home sooner and finding me tied up. It turns me on even more. I even left the room door open to expose myself to everyone entering the apartment. It took the key more than an hour to melt. When I was releasing myself I noticed that the door was closed! I was sure the door just closed by itself. But then I saw her pink backpack was gone! I was so embarrassed I cannot describe, Well We never talked about it. But I can’t stop the feeling that things aren’t quite the same between us… Do you have ever been caught, and if so in what embarrassing position?
