Childhood Friends & A Foxy Oracle

The trouble maker foxgirl oracle is my childhood friend!?

[Story]
Chizuru, the daughter of a family that maintain a small Shinto shrine, secretly harbors feelings for her childhood friend Kouichi. When they were young, the two often played together with a foxgirl oracle by the name of Kuu-ko.

As they grew older, Kouichi lost his memory of Kuu-ko.
However, due to her family's spiritual lineage, Chizuru was able to maintain her connection to Kuu-ko and the two grew up together like sisters.
Kuu-ko is well aware of Chizuru's feelings for Kouichi, and has watched over them... until now.

One day, Kuu-ko teases Chizuru about her indecisiveness towards Kouichi and the two end up quarrelling. Having worked herself up into a fit, Kuu-ko possesses Chizuru's body, and decides to take matters into her own hands by directly approaching Kouichi.

Chizuru, who's spirit has been ejected from her body, attempts to stop Kuu-ko, but her resistance is futile.

Kuu-ko proceeds to invite Kouichi into the shrine where they played as children... and seduces Kouichi with Chizuru's body. Unable to resist her temptations, he mounts and kisses her...
Kuu-ko herself gets in the mood and the two get down and dirty together.

Chizuru can only standby and watch as Kouichi passionately makes love to her body...
Which in turn gets her hot and horny too... Unable to hold back, she begins to touch herself...
