This work features play footage originally published in an SM magazine. The protagonist, Kikue, is a company president's wife who has never been involved with any man other than her husband. However, she falls into a trap set by her younger sister, Mitsuiko, and is captured by her brother-in-law, Ryo, a sadomasochistic pervert. Under his intense training, Kikue experiences extreme pleasures such as vaginal stretching and fisting, gradually transforming into a complete female dog. In this episode, Kikue is depicted traveling naked to a hotel, then graphically shown taking her brother-in-law's erect penis and her sister's penis strap-on simultaneously. The explicit, intense portrayal of an innocent wife's gradual descent into sexual depravity delivers powerful shock and arousal to viewers.
