Jack is doing some flexing and stretching for you. He's so casually cool and effortlessly handsome. He plays sports all the time so he's naturally strong. Not like a bodybuilder. But just strong from being young and playing sports all the time. I love his V shaped back. Let me calm down. I digress. What was I saying? Oh yes! Jack is doing some upper torso muscle flexing for you. Enjoy you flex lovers.
