Woman of Gor
Fabian Perez
(As performed in Explorers of Gor)

" I hear from the chain master," said Samos, "that you have learned the tile dance creditably."

The tiny cups and glasses shook on the tray. "I am pleased," she said, "if Krobus should think so."

The tile dance is commonly performed on red tiles, usually beneath the slave ring of the master's couch. The girl performs the dance
on her back, her stomach and sides.

Usually her neck is chained to the slave ring. The dance signifies the restlessness, the misery, of a love starved slave girl. It is a
premise of the dance that the girl moves and twists, and squirms, in her need, as if she is completely alone, as if her need is known
only to herself; then, supposedly, the master surprises her, and she attempts to suppress the helplessness and torment of her
needs; then, failing this, surrendering her pride in its final shred, she writhes openly, piteously, before him, begging him to deign to
touch her. Needless to say, the entire dance is observed by the master, and this, in fact, of course, is known to both the dancer
and her audience, the master.

The tile dance, for simple psychological and behavioral reasons, having to do with the submission context and the motions of the
body, can piteously arouse even a captured, cold free woman; in the case of a slave, of course, it can make her scream and sob
with need.

Sometimes the Dance of Seduction is also called the Dance of red tiles.
