A Passion for Bondage 9: The Self-Bondage Club

Mary is a single young woman with a strong love of feeling helpless, as in being tied up. However, the poor girl lacks a partner to provide that service and is too embarrassed to admit to anyone that she is as kinky as can be, so she resorts to doing it herself, usually with handcuffs and the key frozen in an ice cube. It's not a good as the real thing but it partly satisfies her kinky desires. Imagine her surprise when she discovers that another woman who works in the same office as she is also into self-bondage.
And even better, she's a member of a group of young ladies, all of whom are heavy into bondage. Let the adventures begin!
