I'd never been to a sex club before. Hell, before I saw the new erotic romance movie, I didn’t even know what BDSM was. I was that naïve. 
Mix together a few shots of alcohol, my dangerously adventurous girlfriend and a dose of curiosity, and you had the recipe for a very crazy night. 
That’s how I ended up inside the sex club.
How did I end up being schooled in the arts of BDSM by my sinfully sexy stepbrother? 
Now that was just pure madness.
