Pleasing the Master

The Master is known for his intense, 24/7 BDSM practice.  When a shy girl with plenty of repressed, dark fantasies enlists his services for the week and immediately gets cuffed and put in a chastity belt, she knows she's in for a lot of pleasurable pain, all over her body and in every hole.

This story is the first installment in the series, and covers Day 1 with the Master.
