I walk in on my son jerking off to porn in the living room of all places. Based on his reaction, he clearly didn't know that I was home. I was too intrigued catching a glimpse of his hard cock that I had to see more. This turned into a bit of a teaching moment where I decided to quiz him to learn if he's ever been with a woman. He had not, so I thought I'd show him what it's like to get a handjob and blowjob.
