I was masturbating in my room and I had my door shut. I was trying the stop and go technique that people always talk about. My girlfriend opens the door and sees me on the bed. She said 'You don't know how to work it at all'
She started using both her hands, teasing the tip of my penis. She went so slow, but worked every inch of my cock. It started to throb like crazy and then she stopped. She began to say 'you want me to keep going don't you?' I nodded and she began to slowly stroke again. This time she worked only the tip and it felt so good.
Again my penis began to throb and she stopped. She said 'Why should I finish you off, what's in it for me?' I said 'Please'. She said 'Since you said please' and started to stroke faster and faster. Before long I came so hard all over her hands and my chest. It was the best orgasm.
