Dr Ami Mercury’s Cockslapping Research Study

I was in need of a little money, so I decided to take part in Dr. Ami Mercury’s research study. I probably should have read over what I was signing up for, but she was hot and I was horny. Oh, did I make a big mistake. She was researching the affects of cockslapping on sperm production. My little cock was bruised and battered in the name of science, and I loved every minute of it.
