So, let me say, this isn't about my biological dad, because I never knew him, but this is about the man I assumed was my dad until I was 14. I always knew my dad jerked off, ever since I found his porno mags under my parents bed. When I found these, I began to become attracted to the fact that he was probably jerking all the time, well at least in my mind he was.
So when I was 15 I decided to start spying on him to try and see if I could catch him, since I was so turned on by the thought of him playing with himself. So I decided I would try to spy on him while in the bathroom. When I went upstairs to his bedroom and saw that his door was locked while my mom was at work. I knew he had to be doing something he didn't want anyone to know he was doing. So I went and got a key that I used to unlock his bedroom door, and I quietly walked through his room toward his bathroom. My parents bedroom had a bathroom in it, without a door in between, so I snuck around their bed, and peaked into the bathroom, and low and behold, what did I see, I saw my dad sitting back on the toilet, with a full erection, pumping away at it. I don't know why, but for some reason he never even looked towards me. I could basically see him from the side view beating his hard throbbing cock. He was looking at a hustler magazine, while playing with himself.
As I watched, I felt my dick begin to become hard within my underwear. I was getting hot all over. I just stood there watching as my dad, took his large penis in his right hand, and beat it over and over. All I wanted to do was to go in there and help him out. His dick was approx six inches long, but very thick. I stood there watching him until he bucked up, and pushing his cock into the bowl area of the toilet, he began to convulse and pant heavily. I realized he was cumming into the toilet, and so I decided I would walk in and surprise him. My dick is fully erect by now, and I'm so turned on. I startled him, with one hand on his dick he looked up at me, and said 'what?', I just made up an excuse while staring at his hard-on. Finally I walked out, and went to the other bathroom downstairs, and began to jack off until I came harder than I have ever came in my life. I love to think back to my peeping days, when I would catch him jacking away.
Next time I'll tell you about catching him jacking off in a penis pump.
