ここは関東某所にあるS特別老人ホーム。一見するとごく普通の介護施設なのだが、そんな老人ホームで触手の餌食となった人妻介護士Mさん。とある日、体を麻痺させる感覚遮断エキスを下半身に打たれ、下半身は感覚遮断で何も気づかない体になる。その豊満な体は知らぬ間に触手に貪られヤラレ放題！感覚復活のトリガーは触手による大量中出し。そして気づいた頃には全身を侵食されて、快感に気づかないまま蓄積された刺激は感覚が戻った瞬間に連続アクメとして解き放たれるのだった…。五感を殺して、悦（エツ）に溺れろ！

This is S Special Nursing Home, located somewhere in the Kanto region. At first glance, it looks like a perfectly ordinary nursing home, but it is there that Ms. M, a married caregiver, falls prey to tentacles. One day, she is injected with a sensory-depriving extract that paralyzes her body, leaving her lower body completely numb and unaware of what is happening. Her voluptuous body is devoured and violated by tentacles without her even realizing it! The trigger for the return of her senses is a massive ejaculation inside her by the tentacles. And before she knows it, her entire body has been invaded, and the stimulation that has accumulated without her realizing the pleasure is unleashed as a series of orgasms the moment her senses return… **** your five senses and drown in pleasure!
