Courtney flexes her 17 inch muscular calves wearing black low heels. She's really starting to get the hang of the muscular calves flexing. She shows them off walking around the courtyard. She also reps both calf muscles at the same time and individually. Nice shots of her heels lifting off the ground as the camera pans up to her flexed calf muscles. There are also full body and closeup shots. Check her out in Hi Res!!
