Caught Masturbating?

How many times have your parents caught you masturbating? My mother has walked in on me twice... :(

When I was a teenager, spice came in scrambled-the audio was perfect, but the video was just screwed up enough that you could make out the various titty and undulations if you got lucky.  So I'd fap to that, sound low and trigger finger on the previous channel button.  I was very careful.  If I suspected movement outside my door, not only did I hit a previous channel, but I would change the channel ONCE MORE so I couldn't be traced.  In fact this worked out once.  My dad busted in my room with his remote, and hit previous channel.  went to something harmless.  He looked at me.  "Good work."  He left me alone after that.  I guess he respected my attention to detail.  XD

If you did the thing with prev. chan + chan change as well lemme know.
