I am rather a strange guy. I like to know why things are the way they are.
One day I was fucking my girlfriend for the second time one night and I thought, "I wonder what my cock is thinking, if I am overworking it or expecting too much from it."
When I shot my load in her cunt, I couldn't help but think if my cock was done for the night or if my cock would be ready for more later on.
My cock never failed me before so I just assumed it would be ready for more later on.
So, I decided to do an experiment.
I know a lot of girls and I have fucked most of them. So, I called them up and asked if they would help me with my experiment.
After they stopped laughing, most of them said they would help.
Now, this wasn't going to be a pure scientific experiment where the results would be published but the results could help me in my sex life.
I arranged for the girls to come over my house every night for a week to fuck. That meant seven girls in seven days which would would put my cock to a good test, figuring on how many times my cock would be able to perform (cum) with each girl.
Prior to beginning the experiment, I didn't jerk off or cum for the whole week before.
Monday night, Diane came over. She is 19, 5'7", 115, brown hair, normal size tits and a great fuck.
We had some wine and then went into the bedroom. By this time my cock was already hard. Obviously, it knew what I was thinking.
We undressed and my cock was ready for action as it was well rested. My cock was in a hurry to get into a warm, wet spot, so I slipped it in her cunt.
Now, my cock was in a hurry but I kept it under control and rested it a bit before I put it to work.
Then, it happened. My cock started thrusting in Diane's cunt without me telling it to. It had a mind of its own, for sure. It wanted to do its job and cum.
