Hi, my name is Liu and I'm a 70-year-old man with a muscular body and small ass. I've lived in this country for over 50 years now and I've seen quite a bit during that time. In fact, one of the most memorable experiences was when I was a young student at the university.
During those days, my financial situation was very difficult and I had to work multiple jobs to make ends meet. One day while working as a cleaner in the school's science department, I accidentally stumbled upon some of the students conducting an experiment on the effects of various substances on semen production.
I can't even begin to describe how excited I was when they invited me to participate in their study. Of course, being the shy Chinese immigrant that I was, I had no idea what they were asking me to do at first. But once I understood, I jumped at the chance.
They led me into a small room where there was a stool and a chalkboard with some written instructions. As soon as I sat down on the stool, I felt my heart racing with anticipation. The students then began to explain what they wanted me to do. They explained that they needed me to masturbate while they recorded the amount of semen that I produced.
At first, I was very nervous and didn't know if I could go through with it. But as soon as they started filming, something inside of me snapped and all of my inhibitions disappeared. I began to masturbate furiously while thinking about all the money that this study would earn me.
As soon as I finished, they instructed me to stand up and pose in front of the chalkboard. They wanted me to show off my body for the camera so that they could document the results of their experiment.
At first, I was hesitant because I had never been naked in public before. But once again, something inside of me took over and I began to undress without thinking about it. When I stood there completely nude in front of the camera, I felt a sense of power that I had never experienced before.
As soon as they finished filming, they paid me handsomely for my participation in their study. From that day forward, I knew that I could do anything if I put my mind to it. And I have been living proof of that ever since.
