stroking with my son

I'm a single father with one son. During my son's teen years I discovered he was a major masturbator like myself. When I was his age, I was stroking my cock day and night. Sometimes, I would beat off alone and sometimes with the two brothers that lived across the street. My own dad caught me a number of time stroking my hard cock. Sometimes mid-session of self-pleasure and other times during the clean up. I even spy on dad a few times jacking his own hard cock. My son Mark started not to be too shy about jacking off around his 16th birthday.

One of the first time I "caught" him was a Sunday morning. I walked into my son's bedroom and found him naked. He was standing naked with his back to me. I asked Mark if he wanted to go to breakfast at the local diner. Mark then turned around facing me. Mark had a huge load of cum on his chest and pubic hairs. His cock was still half hard and greasy. Both of his hands were also greasy. Mark just smiled at me and said "yeah, I'm hungry. I'm going to jump in the shower first." I left his room and when into my bedroom and removed my robe, and when I heard the shower come on and then started stroking my dick. I stroked my hard cock fast and furious. Listening to the sound of the shower and in my mind the vision of my own son with his cum on his chest. Just as the shower shut off I blew my load. I then cleaned up my load and took my own shower.
