I went back in to the school's clinic, because they wanted to do some more research on their new drug. When I arrived there was a different doctor that was going to be doing the research. His name was Dr. James and he gave both Eric and I some of the medicine for to try a second time once we were back to the room. This time the sexual drug did not taste as bad, for us to try. The doctor had Eric get up on the table and take off his shirt. When doing his exam he found that he was warm, and so the pants and briefs came right off. Dr. James started to touch and even give head to Eric. I noticed that I was starting to feel very warm from the drug, so he had me strip down to my briefs. The doctor had me start to give Eric head, while he was playing with my cock. The three of us were missing around together with everyone getting touched boners were starting to form. Dr. James and I both worked on sucking on Eric's cock at the same time and that was a lot of fun for me. Eric pulled me up towards his head and he started to suck on my cock. The doctor was naked along with us, and had a very nice body from head to toe. Servicing his cock Eric made sure to give the doctor all the attention that he needed. And at one point I switched places with Eric and took the place for being on the table. I focused most of my attention to giving the doctor great head. What we did was rotated around the room giving everyone a chance to be on the exam table and having two mouths service their cock. It was the doctor that was last to take his turn on the table. Afterward Dr. James had me get up on the table and start to jerk off until the point when I could cum. For me to get off, I have to stroke my cock pretty hard in order for me to have an orgasm. My body has to be tense and I have to pound my dick very hard. I yelled out to have someone play with my balls and the doctor's hand was right in there touching them. Eric was a very loud moaner, and I could tell that the two of them were just wanting me to shoot my load all over myself. I was working up a sweat stroking my cock so hard, but everyone was still having a good time. To my surprise, Eric couldn't hold back his load any more, and came right on my side. He then began to rub my leg as he calmed down. The doctor was starting to stroke his cock really fast, and acting like he was getting close. I knew that he was about to go and bust his nut right on my side. He gave me a warning and shot his load right on my lower stomach right at the base of my cock. As soon as he had came, then I started to feel the cum about to shoot out of my cock. My load landed on my cock and leg. I was out of breathe, but thanked the Doctor for helping me. He asked us to come back for one final test tomorrow, and how can I turn down an opportunity to make some more money. I look forward to coming back into the school's clinic.
