Yuri is an ordinary, plain-looking married woman who wears glasses. Her husband is addicted to drugs, engaging in chemsex daily. This has driven her mental state to the brink—whenever she's high, her libido runs wild, though she remembers nothing afterward. The protagonist is a regular office worker, living a mundane life with no girlfriend. One day, a strange couple moves in next door. The wife is a quiet, unassuming woman with glasses, but her husband clearly acts suspiciously, possibly using drugs. One evening, the protagonist hears moaning from outside. Hesitantly opening the door, he sees the plain-looking, bespectacled wife masturbating in a wide M shape, drool dripping from her mouth. Her cries are desperate: "Aaaahhh~ uuuuhhh~ an-an-an-an-an-an-an-an-an-an-an-an! I'gghhh! I'gghhh!" Shocked and traumatized, he freezes in place. The wife, clearly under the influence, locks eyes with him and gives an unbelievably skilled blowjob. Overwhelmed by pleasure, he cums instantly. Afterward, she forces him to take pills, dragging him into intense chemsex. Her massive tits bounce wildly as her entire body trembles—every inch of her skin turned hypersensitive. Rumor has it she once worked in a pink salon. As the protagonist unleashes all his pent-up stress, he gradually loses control, becoming aroused, submissive, and completely feminized. Again and again, he cums inside her, his sperm drained until he's completely dry. In the end, he loses his memories, his mind shattered—ceasing to be human. This work portrays an extreme experience where madness and desire collide. [Celebrating KMP's 20th Anniversary!!]
