It's really just muscles sliding under skin
Maybe a well-placed bit of fat
Lush roundness to smooth the curves

Yet it pulls the eye off course
Perfect geometry as line folds into shadow
Folds again into still-hidden geometries

You want to sketch, to freeze that moment
Capture the mind in the transition forever
But then the next change would be lost

So instead you try not to stare and think
It's really just muscles sliding under skin
That makes you think of skin on skin
