It's quite a surreal story. I was downstairs late at night just after my eighteenth birthday and everybody else had gone to bed. I know that my dad subscribes to some unsavoury channels so I flicked over to them and put in the pin that I had acquired through much patience.
There was all the soft porn I could ask for, tits and ass on all over the place. I started to get a little hot so I undid my button and took out my semi and stroked it a while.
I was just in my shorts and t-shirt, and I jumped to see my dad behind dressed fully in his jeans and t-shirt he wears for work when he'd gone to bed ages ago. He said to me, 'What you watchin?', completely patronisingly with a cheesy grin on his face. I was dumb struck sat there with my shorts pushing my balls up right into view and my dick in hand with the porn on the tv. There was NO way of explaining it away!
I guess I went white, and was incapable of speaking. We both sat watching the porn, me with bone showing as I didn't dare put it away.
Next thing I know he pulls his out, much the same as mine and starts thrashing at it, 'You can do it too' he said indignantly so slowly I started. As we got into it I relaxed and he took my dick in his hand and thrashed it. So I did the same and we did it, he got into it more, started squirming and what have you, but I came first. It was odd!
