My oldest son is 12, I also have an 11 year old and an 8 year old, and have never been caught in the act of sex till a couple of weeks ago. Luckily it was only my son who is 8. He really doesn't know what was going on he is autistic and is not in that kind of mind set yet. I would have died if it was my older son. Has anyone else been caught by there kids and if so how do you explain it to them?
