Today I had a new candidate for a study we were running on the campus walk into the office. He saw a flyer and brought it into the office and presented it to me so I said," Step right up and sit on the examination table. I explained the study geared towards gentlemen with extra large penises. He told me he would be more than welcome to show me what he was working with. So he dropped his pants and boy was I taken back with the size of his soft cock. He must have been at least six inches soft. When that monster started getting hard it became a whooping thick nine incher. I covered it in lube and started to jerk his mammoth dick. It felt so thick in my hand and I could feel every pulse. I got the petri dish ready as I felt his cock head swell and start to spew a nice thick load from his dick. I was definitely ready to see some more from this guy.
