Sayo ITANA, incest, mother and child fertilization

I have a secret that my husband can't tell. I actually had a physical relationship with my son. One day, when I was taking a bath, my son looked at me. Then the action gradually escalated. At first, I thought that if you treat it with your hand or mouth, you would be satisfied, but the cock remained hard and finally crossed the line. I know that it will be difficult if I get caught up in my husband, but if my beloved son thinks he wants it, I can't refuse it either.
