We are in La Siora, Tokyo's most established dominatrix house - a dimly lit den of debauchery with wall-to-wall implements to satisfy one's most perverse desires. We are greeted by Rie, manageress and head dominatrix of the establishment, who is beautiful and immaculately groomed. Her hair is curled to perfection, her face is pretty, and she volunteers the information that she "likes to whip" as we walk to the main apartment where all the action takes place.

We witness a session that doesn't seem to differ stylistically to what the West has to offer, although the doms are particularly skilled and La Siora boasts an impressive client database of about 4,000 slaves.
