Gage saw one of the many flyers on Campus looking for sperm donors for lab experiments and came in to see what it was all about. After checking to make sure his heart was safe for sexual activity I decided to check his temperature just to make sure he was tip top. Just as I was about to start jacking his dick the phone rang. It was the X-ray room. One of the technicians overloaded the control panel and asked for my assistance in resetting the device. So I left Gage to squeeze one out on his own. When I returned to the exam room Gage had just dropping a massive cum load in my collection jar.
