Incestuous [silence] Incest. My father is next door...

I knew my son had been acting strange lately. He was licking my body and masturbating using my underwear. However, I didn't think much of it because I thought it was due to the stress of taking university entrance exams. That's when the incident happened. While I was video chatting with my husband who was on a business trip, my son suddenly started touching me... Then, in front of her husband and unable to speak, she ended up having an affair with her own son.
