This time, the one who came to my fuck room was "rena". She is my son's new wife. They've been together since college, and it seems they haven't had sex since getting married, so I'm comforting her instead of my son. At first, he genuinely hated it and I was worried that my son would rat me out, but as we did it more times, he seemed to get along well with my cock. He started initiating oral sex himself and tried to insert my cock into his wet pussy. Is this a sense of immorality? The more I think it's bad for my son, the more fiercely I move her hips, and as usual, I gave her a good filling with my middle-aged semen deep inside.
