I'm Thelma, a 30-year-old divorcee with a 14-year-old son. We've been having sex together since he was 12. It just happened one evening when Chris got a hard-on and I just couldn't resist it. I had never thought about incest before, but now I'm into it I can't stop. No other sex is like it. When my son is at school I often bring myself off with my vibrator imagining it to be my son's cock. He fucks me four or five times a night and always leaves me exhausted.
