pencil e story: Konya Takashi

The volume is in Japanese, so I can only guess the story.
Fantasy tale set in a Japanese high school.
A beautiful succubus reaches Earth, but is quickly joined by a blonde rival.
Her origin makes her easily succumbing to the power of creatures from her own dimension.
A look is enough for the blonde to subdue and possess her.
The young woman is saved by the King of her kingdom, in love with her, but a little shy.
After sending the blonde back to the demonic realm, the two enroll in high school, but end up meeting another blue-haired succubus.
Also this time the protagonist is subdued and forced to satisfy, in addition to her rival, also the King, who ends up having a complete intercourse with her by deception.
A rather simple and not too pushed story, which plays on the classic insecurities of adolescence.
