This work is presented as a video recording of a session published in an SM magazine's editorial department. The protagonist is Kikue, a company president's wife who has never been involved with any man other than her husband. Trapped by a scheme orchestrated by her younger sister, Mitsuko, Kikue is captured by her brother-in-law Ryo, a sadomasochistic pervert, and forced into a life as his sex slave. On this day, a man claiming to be Ryo's subordinate joins in, brutally assaulting Kikue's anus. Initially tormented in both orifices using thick vaginal vibrators, she gradually has Ryo's extremely large cock forced into her ass, then is made to take the subordinate's cock as well. With each act, Kikue experiences simultaneous humiliation and pleasure, being completely drawn under Ryo's domination.
