Kristen was so sexy in her cutoff jean shorts so I had to get her in a pair of black high heels in them. She walks in the heels and flexes her calf muscles in all positions. She reps both together and solo. She shows muscle control with bending each leg up behind her and making her calf muscles jump. Watch her rock hard vascular calf muscles contract as she walks and flex in her high heels in Hi Res!!
