Ejaculates inside his mother and to his father

my son and I are fuck in secret. The verity is that satisfies me more than his father. I want that our sex will last forever. But my son is always reckless and wants to fuck all day, every day. Does not matter if the father is at home or not. Last week at dinner, my son started to jerk off. I did everything I could to stop it, but it was useless. Before I could do anything, he had already ripped off my underwear and put my fingers into my pussy. When my husband left the table, I was very horny and I made him a blowjob. And I am sitting on him so that I penetrate, but at that moment my husband arrived back and my son got me ejaculate in front of him.
