Dark Alpha Side of The Billionaire's Mistress

Nathan is happily married to a beautiful woman who he is in love with. But, he's also got another beautiful woman on the side who gives him what his wife will not. Nathan feels like he has to choose between these two women that he loves.
Elisa, his beautiful wife, who has stuck by his side through thick and thin and is the woman that he has always wanted. Despite all of his money, she does not allow it to change how she lives her life and she continues to live her life as if she does not have a husband who has billions of dollars in the bank.
And then there is Natalia. The sexy secretary whom he knew about but did not know all about until he met her in a BDSM dungeon. When he learned that she was into BDSM, they began to casually sleep around, but it slowly turned into something more!
With Natalia, Nathan gets something that refreshes his soul and helps him to get past what he is not getting with Elisa. Nathan, despite how much money he has, does not throw it around to keep the women in his life. He keeps them both. Needs them both.
In the end, Nathan has the best of both worlds!
