Choked by the stench of men and the madness of love, a "perverted old man" devours a girl's heart and body to the very marrow. Once caught, there's no escape—this is a story of a girl and an old man. A pleasure-training omnibus drowning in an excessively thick taboo situation, where even the viewer is swallowed by that madness.
If you like J-style girls, I recommend this. This work is an omnibus format where 12 J-school girls encounter erotic developments in various situations. Personally, I recommend the first episode the most. The first story has a high level of completion as an introduction, and it effectively builds anticipation for the other episodes.
