Welcome to Room 13, where submissive men confess their sins and are properly punished…

It's not easy leading a double life, especially when you have an overprotective best friend who assumes you're asleep by seven o'clock every night.

To Jennifer, I'm a vanilla librarian, a woman who's perfectly content shelving books and reading in bed with a cup of herbal tea.

However, I'm actually Mistress Klara: an unrelenting Dominatrix with a carnal desire for BDSM.

At the Dungeons, I'm able to shed my dull, bland librarian persona and embrace my inner sexuality.

Those who visit me are introduced to Female Supremacy via leather cuffs, leather whips, and even a leather collar.

Their bodies will shudder once they realize what they've signed up for, too.

A scrawny computer hacker will beg for absolution.

A tough cowboy who exudes Alpha energy will enjoy a different kind of meal while being restrained.

I might even have a little bit of fun with a couple, too.

All of them will be torn between crying out for help and begging me to punish them harder.

Perhaps the best part, however, is that my true identity is hidden behind a mask.

Not too shabby for a vanilla librarian, if I do say so myself.
