After he was done the next thing that he had to accomplish was getting a sample and to do that he needed me to get hard. The Doc gave me an option, I could get rock-hard myself or I could have his help to do it. I thought for just a second before I replied and said that I would take his help. Gripping my dick, he took a hard hold of it, and positioned my boner in his mouth for him to embark throating on. Dr. Topnbottom was very great at providing head, and able to get me hard. He would twist his head from side to side, and in an up and down movement at the same time. After a while of it though, I could tell that he was getting weakened and he asked me to take over and jerk off. I did so and as I got close to shooting my load, I told him and he took over stroking me off. I restrained back as lengthy as I could and I shot a couple times over the cup that he had in his hand. Squeezing my man meat forward I couldn't help, but setup since my prick was so sensitive. As soon as the last drop was out, the Doc said that he dreamed a taste of his own medicine.
