I want to bury my head in the sand.

My parents walked in on me yesterday masturbating, I found a double d**** in my older sisters room, Everyone was away for the day or so I thought, I hopped on my bed, Didn't lock the door because I didn't expect to get caught and was in the middle of enjoying myself when my door opened.
Let me set the scene, I had one end in me and the other end lubed up and was pretending to jack it off, buck nude and no way to hide.
F***...
