Heath is always bone hard for his shoots. Most viewers like to see a dude go "balls deep" on a dude, but Heath knows his dick has a long reach. He monitors his depth by not diving in too far, and yet still keeps hard.
This works for Chip who often has to keep a hand on his partners leg to make sure they don't hit his spleen. Given that Heath is decently hung, Chip was rarely jerking away from Heath's dick.
Also given the challenge of fucking on the massage table, the two did great together. And Heath really gives Chip a nice "internal" massage.
Heath also was about to cum through most of this shoot, so fucking Chip till he cums was pretty easy and it is an awesome breeding session!
