Welcome Kate. Although she is too modest to say it,
@Eulalia has written and posted many of the best sub stories on the site.
Check the Archives for:
For The Pleasure Of Prince Uday - a girl to be whipped
The Interrogation and Punishment Centre for Girls - an expansive classic
Lassie Hunting in the Northern Forest - an ancient and honorable sport
Beauty and the Russian Beast - so prolonged suffering!
And several other excellent works.
My one, half-hearted effort in that direction was A Slave's Diary, mostly a sugary romance disguised as a Master/Slave relationship.
Agin Welcome!
