Two straight, muscular fitness enthusiasts, both adorned with intricate tattoos, challenge each other to a unique workout routine. As they oil up and flex, their competitive nature turns into something more primal. They start with dick-sucking exercises, the thick, cut cocks slipping in and out of eager mouths. Soon, one bent over the workout bench, his ass ready for the next set. The other, curious and excited, lubes up and slides his massive cock into the tight, virgin hole. They moan and grunt, the bottom's ass stretching to accommodate the intense pounding.
