Pleasing the Partner by Annika Rhyder

Zora:

Zora’s husband isn’t the man she thought he was. He’s actually an embezzling, cheating, gambling addict, and he’s offered her to his firm’s senior partner to buy his way out of trouble. That should outrage her, and she should definitely refuse to go along with it. Except Sterling Ashe is temptation itself. With his commanding personality, contrasting with his tender side, he’s nothing like Jim, and everything she’s ever wanted.

Sterling:

She’s been his since he first laid eyes on her despite the ring on her finger from another man. When her jerk of a husband makes his terrible offer, Sterling seizes the chance to offer Zora a way out of the mess Jim created and a way into his life. Now that he has her, he’s never letting her go. He’ll do anything to keep her, including filling her womb with his baby.
