I was watching a movie with my aunt one night and got aroused. My penis was really stiff and the boner would not go away. I pretended to go to sleep because I thought she might start masturbating since there was a major sex scene in the movie. I could tell she was watching the people in the movie make love very intently, and so was I.

I could see her out of my mostly closed eyes as she kept looking over at me to see if I was asleep. As I pretended to be asleep, she rewound the DVD to the sex scene in the move, and then she finally she started masturbating.

She opened her big legs and pushed her underwear to the side as she started rubbing her pink hairy vagina. I was under a blanket, so I took of my pants and began to trust my penis back and forth against my hands. I kept my hands flat against my body so I could masturbate my penis without making the covers go up and down.

I think she saw me, so she stopped and came over. She lifted up the blanket to find me with an erection from masturbating. Since everything was out in the open now and there were no more "surprises", I decided to make one more "surprise". I reached up and opened her private parts. She was shocked! But then she told me to take my clothes off and lay down next to her. I said I would if she would get naked and stand over me first. I reached up and spread apart her vagina and started rubbing myself against the carpet. MY aunt then layed down on the bed and began masturbating herself again while I pumped up and down as fast as I could on my penis.

I finally started to ejaculate and it was an amazing feeling. Although I have had sex with women many times, this was the first time I ever masturbated with a woman watching me. Not to mention, this was quite taboo since this was technically my aunt. About a minute later she yelled, "Oh my God… Oh my…" as she came to a shuddering orgasm.

Strangely enough, we never mentioned this to one another and we have not done it again since. It has been over a year since this incident happened. I think about it sometimes when I masturbate by myself. I wonder if she thinks about the experience when she masturbates by herself.
