I came home one day and found my 15 year old son jerking off in front of our computer. Everyone else was out of the house for the day, and I'm sure that he wasn't expecting me to be home so early. He was sitting there as comfortable as he could be, completely naked except for his socks. He had his feet up on the computer desk, and his legs were spread out like he was about to give birth.

At first I was a little pissed off about all of this. Not because he was playing with himself, but just a couple of months earlier I had to pay $200 to clean a whole bunch of viruses out of the computer after he went on some infected porn sites. There was no way I wanted to do that again, so I figured there might be something I could do to make him stop.

I walked into his room as quietly as I could and stood behind his chair. With the volume up as high as it was, he never heard a thing. He had his hard cock in his hand, and he was stroking it in rhythm with the action on the screen. I admit that I was somewhat impressed by my son's size. At 15 his cock was probably as big as his father's, and I wondered how big it might eventually become.

I had no plan as to what I was going to do, but this is how it started, and then things got a little out-of-hand, so to speak.

I gently put my hands on my son's shoulders and brought my mouth to his ear and asked, "What's going on sweetheart??"

Needless to say my son's heart probably skipped a beat or two, or three. He said nothing, and then his initial paralysis was quickly followed by a futile attempt to run. Because of his awkward position, a small amount of pressure applied to his shoulders was all I needed to keep him in place. Funny thing was, he still had his cock in his hand.

"Lower that," I demanded.

My son finally let go of his cock and lowered the grunting dialog of the video, and then I asked, "Watching some porn??"

There was still no verbal response from my son.

"Having a little bit of fun jerking off??" I asked. I then went on a strange little rant, thinking of a couple of other ways I knew that one could say jerking off. "Pulling your chain?? Slapping the monkey?? Pulling your pud?? Greasing the pipe?? Yankin' your crank??"

The silence was deafening as my son's hard cock continued to point straight into the air.

"So who we watching??" I asked.

I looked at the screen as some very hot, older-looking woman with bleached blond hair was sliding her shaved pussy up and down on some younger guy's hard cock. And I have to admit that the sight of these two people fucking, "making love" does not describe what they were doing, did have an effect on me. I grew attracted to the young man's ripped body, his huge, hard cock, and I began to wonder what it would be like to "fuck" someone half my age.

"Boy, she looks like she's as old as me. Shit, she's old enough to be your mom. Is that what turns you on baby?? Is that what you like?? Do you want some old lady to make you cum??"

I suppose that my thinking went crazy just about then. I was still watching the action on the computer screen. They were now fucking doggie style, and this guy was just slamming this woman's pussy as hard as he could. And she was liking it, asking him to fuck her even harder, and I suppose I asked myself, "Why couldn't that be me??".

"How about your own mother??" I asked my son. "How about me?? Would you like me to jerk you off. I can you know. I can make you cum. You don't have to watch porn on the computer. Just come and ask me. I'm pretty good at giving a guy a hand job, or even a blowjob. Just ask your father."

The next thing I know I've got my hand over my son's cock and I'm stroking it. My eyes keep flicking back and forth, watching the couple on the computer, and then looking at my son's cock. I notice that my hand isn't sliding good enough. There's too much friction, so I put my head over my son's cock, and I let my spit drip over it. Instantly my hand is slipping over my son's cock as if he had dipped it in oil, and the next thing I know, cum is shooting everywhere.

I milked my son's cock until it was dry, and then I wiped my cum covered fingers onto his balls.

"Don't look at porn on the internet," I warned my son sternly. "I can't afford paying to fix a computer every time you fuck it up. Go out and buy some magazines if you want to jerk off."

I walked out of the room and never said a word to anyone about what had happened. I knew my son would keep quiet too.

I never caught my son jerking off again. I assume that he was just more careful. And I'm sure he still went online, because it wasn't long before he bought his own computer. This happened four years ago, and I still think about that day. I wish I could tell my son that I'm sorry for what I did, but I have to admit that I had fun. Sometimes I wonder how big his cock is now.
