Stephen doesn't just want his stepsister, Diane, for a day. After years of frustration, having her close but not being able to claim her, his need for her could never be resolved so quickly. If she wants him to appoint her as head of their Non-Profit Department, then she's going to have to work for it. At her desk. On her knees. And on her back. She might try to deny she wants him. But one thing she can't expect is that Stephen is more than just a young billionaire. He's a demon. And because he can read her mind, he knows exactly what his half-angel stepsister needs, even if she could never ask for it. Each day training with him will teach her something new. About business. And about herself. Because mistakes in the business world have consequences, and Stephen will be there every step of the way to enforce those consequences. ~My Billionaire Stepbrother: Internship Day Two is roughly 2,000 words and all characters involved are over eighteen.
