I find,

The glitter of her teeth
Is directly proportional
To the width of her grin
And a narrowing of chin

Also,

She has shallow sparkling eyes
Of raw want and feminine whys
Like cool blue in crimson skies
Like black nights and fireflies

And then,

The softness (and so innocence)
of her wheat-and-marble skin
Belies a surprising ability
And a fine propensity to sin
