“I'll do it. I'll do anything you want”Raiden clicked his tongue in a disapproving tone then raised Hiro's head once more.“That's not what I want to hear, Hiro” He said. “I want to hear you say it with your lips. I want to hear you acknowledge what you will be to me and your status from this day henceforth.”He stared deep into Hiro's beautiful brown eyes as he spoke; “Say that from this very second, you belong to me. Your body, your soul, your mind, every part of you belongs to me. You will be my pet and remain by my side. You will do whatever I ask you to do. Tell me that I own you, Hiro.”Raiden's voice was frighteningly deep and Hiro felt shivers run down his spine.

Every part of me is yours. My body, my mind, my soul, everything is yours. I will be your pet. I will do anything you ask of me. I will give you everything that I am.
