I have had that talk between a father and his son. It was a little awkward, but I was okay with it and my son seemed fine. I told him about what sex is and how babies are made and that men and women can please themselves in private when they have the urge. I know he masturbates because I do his laundry. That is why I knew I had to give him the talk when he had a wet dream. I see tissues and I know he is having a healthy masturbation life.
But recently, things seem a little more obvious. The tissues used to always be in the waste basket and if someone else were to talk in the room, you would never know. Until recently, tissues were just on the floor and lube on the table. At first I thought that was just an accident but then he one day he left our iPad on and the music was still playing so I went to turn it off. But it was porn. It was daddy and son porn.
It was hot porn, I jacked off right there in his room. I used his cum from the tissues to jack my dick off. I imagined him walking in on me like in the porn. It was the best jerk off, I shot four thick ropes. I cleaned myself off and continued to do the laundry.
I keep getting weird hints, like the other night he showered with the door cracked. He tends to leave a lot of porn on our iPad. It is one thing to have it on his laptop, but we share an iPad and he doesn't even try to hide his history. Weird porn links like getting caught, and sleeping and daddy porn are often linked. I have yet to catch him, but part of me wants to in order to understand why. I am a little scared to find out, but I want to see where it goes. Nothing beyond mutual masturbation though.
