Hobbyist

 Her hobby is to humiliate public footslaves whenever and wherever she can, by having them kiss her feet

She spots another prey that she can exploit as part of her hobby

'You're gonna kiss my feet, slave!'

'Yes, mistress. At once mistress-madam.'

She skilfully switches her long-socked legs in front of my face

From my lowly and impotent position, I can observe the lines of stitching in her orange socks...

...socks which tower over my humble head as I taste her shoes

Several times she switches feet in front of my face...

...just to add to my humiliation!

Then she turns and walks away in triumph - another public footslave humiliated at her feet and socks!

She knows she is an infinitely better being than the slave she is leaving behind in the dirt

She's a goddess...

...whereas he is just a common-or-garden, public humble head...

...fit only to look her in the sock and shoe

Her sock creases are the highlight of his humble day!

How he looks up to her socks - though not above the ankles!
