The History of Queening:  

The use of the male face, nose, lips and tongue to give sexual pleasure to a woman was first recorded in Egyptian hieroglyphs. The courts of ancient China also record how long tongued male slaves were specially trained to be used by the ladies at court.  Once the slave was in position, the ladies would lift their skirts and use them to cover the entire scenario.  Gentle rhythmic hip and buttock movements meant they could enjoy private orgasms with others present.  Japan too copied this practice in its brothels, whilst in India graffiti still exists depicting similar scenes with gowned girls obviously in ecstasy, queening male submissives whilst gazing upon an enormous erection!  Queening also has a long tradition in the West.  In medieval times pages would provide "lip service" under their mistresses' skirts when their husbands were away in battle, enabling them to remain technically faithful!

Face sitting requires the proper balance between pleasing the dominant woman’s intimate senses and the dominance power of controlling the way the submissive man under her gasps for breath. In fact it’s not hard to realize that any man smothered under a woman’s ass will have a hard time trying to breathe, getting only the air that his superior Mistress allows him too.

Yes, you can say that the Lady has his life under her power and that is why face sitting is an art.

Furthermore, men are quite often required to perform some sort of oral service, be it ass worship or pussy licking.

While eating the dominatrix’s pussy is a sexual act, catering for her sexual needs, pleasure and gratification, ass worship is quite different.

Naturally it is also quite pleasant for the dominant lady having her ass rimmed by a submissive tongue but, bearing in mind that the ass is often associated with everything that is dirty within the human body, ass worship is also a meaningful female domination act because it represents the way the slave has to prove his devotion to the dominant lady that own, abuse and controls him.
