Lethal Calves does simple calf raises in this clip. The girl is gifted in the calf department, as you shall see. She is barefooted. Her hard edged calf muscles appear under her pink skin when she flexes. Up and down she goes on one foot, the vein on her hard calf getting bigger and bigger as she does. Her Achilles tendons are sharp. The higher up on her toes she goes, the harder her calf muscles get.
