You release her

You walk up to Rebecca in her cell, and you unlock the straps of the straitjacket holding her arms.

"Why did you do that?" she asks as she gets her arms out of the straitjacket with routine moves.

"I want in," you tell her. But even now your legs are trembling. And you can barely believe that you actually released her. Are you ready to go through this? Are you ready to live the rest of your life as a ****?

Rebecca senses your indecision, and she quickly steps behind you, grabbing one of your arms and forcing you to kneel. You could get out of her hold if you wanted. You have the training for it. Problem is: you don't. Instead you endure as Rebecca dresses you naked, then she locks you into the very same straitjacket that you made her wear when she was captured.

"And now we are going to have some fun you and I," Rebecca says smiling.
