Boot worship
From the Internet (and so true)
Boot worship is an act of reverence and devotion, where the submissive shows his admiration by paying attention to the boots of the dominant lady.
It is not just about the physical action of kissing or cleaning; it is about embracing the power dynamic, the symbolism of being at the feet of a femdom.
Through this ritual, the submissive male acknowledges his place under the Dominant and reinforces his submission with every touch, kiss, or cleaning. The dominant woman reigns in the worship, knowing that she deserves so much respect and desire.
Worship, when done properly, is an act of pure devotion, a gift from the submissive to the Goddess.
