Golden Angel, Unwilling Sex Slave 1: The Abduction of Number Seven - Claire Thompson
I’ve read a few books with BDSM that came close to being offensive and this one was standing at line. Laura was happy working in a gentleman club’s when a gorgeous man invited her to a test in a model agency, but the truth is he was just getting to know her secrets and family, because his real job was to scout new girls for a very close circle of Masters.

So Laura was kidnapped and suffered a lot in her first house. Her new masters decided she should enjoy a beating per day and even enjoy it. She was supposed to lose her name and forget her old life. Her new life was treasure some twisted people and accept everything.
