You are on the floor watching the size 9s of Christal Bentley as she poses her calves. Her powerful feet are smashing into the rug. With each change of pose, her toes scrunch up, their edges get white with the stress of flexing. You see the thick sole of one foot as she holds on tiptoe, and this makes you feel very, very good. You realize how powerful is this big girl and you have an orgasm, just thinking about her strength.
