,p>That's what the biceps on these muscular women look like! The rock of Gibraltar!! The first scene is not strictly muscle control, but she pops it up till it threatens to burst through her skin! Again and again! A huge peak on this woman!!

The second scene is more traditional muscle control. And this woman has a huge arm!! You can see her pecs bulging too on some of the flexes!
