The more the doctor stroked the harder my dick got, so when he had to use two hands to stroke that was a good sign to start. Putting these two blue strips on my dick at different parts, they were a little tight. It only took a few more moments at this level, and I told him that I was going to shoot my load. Everyone needed to have one of these machines at home. He told me that he had another experiment that I could take part in, and to come back next week at the same exact time.
