Love in Training: The Wolf and the Kitten

Miyuki has a crush on her boss, Kurama. When she boldly confessed her feelings for him, Kurama told her that he has always liked her too...... But he asked her, "Are you sure about this? I have a sadistic fetish......" As Miyuki became more and more devoted to Kurama, she accepted everything he had to offer as she's disciplined both physically and mentally. It's an extreme and lewd love story between a dominant gentleman and an innocent maiden! (Source: Opal Bunko, translated)
