Japanese men that partake in these kinds of bondage Japan BDSM videos are always fucked up in the head. I wont go through all the details, but one of the men kills someone, with his lover watching. He then takes her, and has her before unspeakable act after unspeakable act, all in a way for him to try to cleanse himself of this sin. He was going to be the new master of her, and she could do nothing but comply, since her love had died. She was now his servant.
