The camera is aimed up at the great big calves of Christal Bentley. Her feet are on the heater and she is flexing, just the way you like it. You see the vein that runs up between the heads of her gastrocs. The more Christal flexes, the more engorged it gets. Now her strong hands run over the tightly stretched skin. You shudder when you see this. It is exciting to see. It is clear that Christal enjoys knowing you are wanking to her muscular calves. She wants you to call her name as your goo flies. Do it.
