Derek is a 32-year-old martial arts instructor with a whole lot of muscle! Like most martial artists, however, he is dedicated to the study of perfecting the body’s skill and discipline rather than using the training for actual fighting. Sean Cody found out that he had never worn a jock strap! So they put him in one and Derek was a great sport about it. The instructor side of him came out a few times as he demonstrated some exercises and martial arts moves, and he was very intense in working his cock. He made the room shake!
