Synopsis: [Ichiba Reika finally lets her be tied up!!] It all started with a phone call from my boss... He had sold me off to a slave trader like I was some kind of bulky trash...

I clung to him, but he looked at me as if he was sizing me up, and began training me in my tied up state without my permission... I was unable to move...
