My biggest fear became my biggest turn-on!
To this day, I still think about it, the day I got caught for the first time after five years of brazen masturbation. I was 18 and lived with my mom and brother. Mom was liberal about sex and so there was no fear of getting yelled at or anything, but the thought of someone walking in on me mortified me. Mom was 38 and looked 10 years younger.
On this particular day, Mom was supposed to take me somewhere, so I had to take a quick shower. I turned on the shower but instead of getting in and doing it there, I laid on the floor naked, holding a tissue. I played with myself for a few minutes. Then she opened the door! I jumped up holding the tissue. My face was flushed! She didn't say a word, and closed the door.
My mind rushed. I had just been caught playing with myself! Suddenly, and surprisingly, this turned me on! The sad thing was, she never mentioned it to me afterward. I wanted so badly to talk to her about it, to ask her if she knew. In the months to come, I tried to get 'caught' by her several times but chickened out each time. I wanted her to walk in on me and acknowledge it with a laugh, or 'whoops' or a gasp. I wanted my pants to be down to my ankles where there would be no covering up. I wanted there to be no doubt.
I still fantasize about being caught. Stories of brothers getting caught by sisters also turn me on. Guess I'm not the only one.
