When I was 14 my 84 year old grand mother fell ill. My parents had to travel up state on week ends to look after her and left this college girl looking after me. I remember doing everything to make her leave and keep my friends from finding out I had a baby sitter. I admit doing horrible things to her to get rid of her and threatened to tell my parents about her bringing in her girl friends into our house. But then my plans fell through when she caught me rubbing my dick in the bathroom. I used to masturbate twice a day, forgot to lock the door and she walked in. Having her tell my parents horrified me. "Maybe know you'll stop being a pest" knowing that the world had just caved inn on me. She knew I was scared and embarrassed and a way to get even with me. She had her girl friends over the next day, told me to take a shower and go to bed. I did it without making any fuss about it and them walked in, removed my towel and clothing, told her girl friend if the wanted to see me naked and dragged me out in front of them. "He likes to jerk off thinking of naked girls" and humiliated me bye sexually arousing me in front of. Turns out what they were watching on TV was much more boring than looking at a naked boy with a hard on that wouldn't quit. The feeling of being watched naked with my penis stiff as a rock, proofed to be the must horribly humiliating experience of my life. She exposed me stark naked, enjoyed the hell out of it, knew I wouldn't dare say anything about it and then made the long walked up the stairs naked to my room. Couldn't sleep a wink that night thinking her girl friends would be there the next day and probably end up the same way. Embarrassing moments and forced to keep them secret.
