Penny Birch 
Regime [EPUB ebook] 

Annabelle is the perfect mistress, and determined to prove it, claiming she can make a submissive woman yearn to be not just her plaything. but her property. Penny is talked into taking up the challenge, to be put through Annabelle’s regime of elaborate sadism and to try and resist the pain, the pleasure and the mind games. At the farm purchased by Annabelle and her boyfriend, Penny is systemically brought low, made into a servant, stripped of her volition and her liberty, treated as a wild animal, and at last made into Annabelle’s pet. By the end she is close to breaking point, and needs only to make the final act of submission.
