A direct correlation between the length of the Biffins Bridge (area between vag and butthole (see also, Derek's Ditch)), and the size of a woman's feet.
My god, she's got size 14 feet. According to Scott's Law, Her biffins bridge must be so long, her asshole will be between her shoulder blades and her fanny just under her tits.
