I saw my mother secretly masturbating while looking at a porn magazine! She was so engrossed in it that she didn't notice me looking, so I asked her "What are you doing?" She got very upset and said "Can you keep it a secret from Dad? If you keep it a secret, I'll do something nice for you," and she pulled down my pants and gave me a blowjob right away! I was upset by the suddenness of it all, but it felt so good that I came.
