Cristal Bentley debuts today as our newest Mongo Big Calves girl. Her calves are 18 solid inches in circumference. That is as big as the average coconut, and take it from the photographer, they are as hard as coconuts. This first clip features Cristal doing one calf raise after another, getting those pins totally jacked. They are massive and vascular. This girl is a brickhouse! Much more to come, so stay tuned.
