Billionaire Bound: My Billionaire Boss, Part 1 (A BDSM Erotic Romance)

Delilah's plan worked a little too well...
She thought a low-level job in the records department of the Stone-Black Corporation would allow her to uncover wrong-doings she could show to the world to take the company down. But after only three days she's suddenly promoted to work as executive assistant to Jackson Stone, mercurial billionaire CEO and number #1 on her list of bastards who deserve a slap in the face.
He has a temper.
He has a secret.
He is absolutely gorgeous.
When he punishes her for snooping around his office, she realizes she may be in over her head.
