From all over the country, futanari girls gather at Maragami Shrine.

The sisters who work there as shrine maidens, Mafuyu and Koharu, spend another day solving the worries of those futanari girls...

Koharu is flustered and panicking over her shrine maiden debut. That's when a visitor, Akiyama Kaede, shows up.

After she states her problem in front of the worship hall, Koharu comes out from the main hall and welcomes her in.

- have a strong habit of fantasizing, and the moment I start thinking dirty thoughts I get hard. (her worry) To solve a problem unique to being futanari, there's nothing to do but decide instantly and act! Koharu takes Kaede's first time.

Mafuyu performs the "goddess descent." The goddess Maragami possesses her and appears!!

Kaede is worked over by Mafuyu and Koharu at the same time, and a violent tremor runs through her body. In that instant she feels that everything is happiness and that everything is being affirmed, and she comes to know a sexual joy she has never experienced before.
