" With effort, Nella shoved the vision aside. “Never.” She drew herself up. “I am a princess of Ariel. I would never—”
“Yes, you would. You will. But I’m glad to hear you get mad at me. That means whoever is chasing you, whoever is trying to make you his slave didn’t break you. You’re whole and strong.”
“Then why do   you   want to break me?”
“I don’t.” Rio stepped closer to her. “I want you to submit to me.”
“What is the difference?”
“There’s a big difference. Submission is complete trust. It’s giving yourself and your pleasure to the hands of your lover. You’ll free yourself, and give yourself entirely to me.”
“If it is so freeing, why do you not submit yourself?”
Rio laughed, a sound so filled with mirth it made her want to smile along. “Tell you what, beautiful. You submit wholly and completely to me— let me train you to be my sub— then I’ll submit to you.”
Nella gave him a suspicious look. “Would you?”
“I never go back on my word, sweetheart. We’ll get Rees to help out if you don’t believe me. He’d be happy to chain me up, although not for the same reasons. He thinks I’m a pain in the ass. "
