Dr Ami Mercury's Cockslapping Research Study

Description: 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.
