Two pec flexers hitting it hard!! The first models big boobs bounce and jiggle from the of her huge pec flex! Very powerful flex!!! This one great flex is looped, slo-moed and zoomed.

The second model has a neat trick, blowing into her thumb to "inflate" her pec muscle! Cool to watch her massive chest muscle pushing her big boob up and out!!! Looped, slo-moed, and zoomed!!
