When I was boy of 15, another boy propositioned me. I naturally (for a 15 year old) recoiled from him. A few days later my younger sister complained about having somebody following her. The next day my admirer made it perfectly clear that he was going to have either her or me, and it was my choice. After school, I followed him into some nearby woods and allowed him to have sex with me. Until he left school, we would have a sexual encounter 2-3 times a week.
I hadn’t seen him for nearly ten years until last month. I met him by accident in a bar, and he picked up exactly where he had left off by threatening my family. So we left together and had intercourse for the first time in nearly a decade. I’ve been meeting him twice a week since to service him.
I’d love to bring this to an end but I have no proof of blackmail, nor do I have any marks on me to indicate being physically forced into sex. I can’t risk my wife or sister being hurt, so I’ve resolved to keep satisfying him sexually for as long as it takes. I’m just terrified that my wife will eventually find out. Should I keep it a secret and hope for the best, or should I tell her. And, if I do decide to tell her, how do you advise me to approach the subject?
