Mark is a personal trainer and does some massage work also. Though he is straight, he works with a lot of gay guys, and is very comfortable around them. He has been talked a few times into messing around with them, so it was natural next step for him to do some guy-on-guy video for ChaosMen. Clearly he spends a fair amount of time in the gym, and even grew his pubes out for this shoot. You can tell he is normally a shaver, so it was great to see some masculine body hair in place. And his cock is a great asset, ample and plump.
