I was sleeping over at my friend's house. Her parents had recently gotten divorced, and she was staying at her fathers' for the weekend. We were a few girls. As these things usually went we stayed up chatting and playing games. After a while everyone else fell asleep, but I couldn't.
From the living room I could hear that the TV was on. I decided to go see what was on, so I snuck out of the bedroom and down the hallway. From the entrance to the living room I could see my friend's father sitting on the sofa. There was some horror flick on the TV he wasn't paying attention to.
On the table between him and the TV was a laptop with something on, and in his hand he was holding his cock, stroking it slowly. Except in some porn some boys shared with me as a joke I'd never seen a man's penis before. I stopped at the sight, startled, but mostly curious. I slowly walked into the room to get a better view. The sight of his hard cock, the glistening head and his hand caressing it was beautiful, it made my whole body tingle.
Suddenly he looked up, and quickly he put his cock back in his sweatpants and slammed the computer shut. - Ehem, what are you doing up? He asked. I told him that I couldn't sleep and that I wanted to watch TV with him. He seemed a bit embarrassed but let me sit next to him on the sofa without any further conversation on what I'd just walked in on. His cock was still hard and his sweatpants formed a neat tent around his crotch as a reminder. I wanted to see more.
