This work compiles footage sent to the editorial department of an SM magazine, focusing on 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, Mitsuiko, Kikue is captured by her brother-in-law, Ryo, a sadomasochism enthusiast, and gradually transforms into a pleasure-seeking female dog obsessed with vaginal stretching and fisting. In this segment, the two sisters are restrained with electric vibrators clamped to their crotches as they compete to reach orgasm first. Kikue climaxes prematurely, leading to her punishment: a fig enema followed by being diapered. The scene unfolds in an intensely graphic and realistic manner, powerfully drawing in the viewer.
