Shoujo Dominance - My Precious Reina -

In a world where the hero has defeated the demon lord and peace has returned…
One of the villages in this world is attacked by a succubus, and the women of the village begin to act strangely…?

Reina’s parents had to be away from home for a while due to work, so she came to stay at the protagonist Hiroki’s house for some time. Since their parents were close, and Hiroki had a responsible older sister, Natsumi, Reina was welcomed warmly.
Although Reina and Hiroki were childhood friends and had played together often since they were little, this was the first time they were living together, so Hiroki was nervous. Reina was quiet and didn’t show her emotions, so their days together were somewhat awkward.
Through the accumulation of these ordinary daily experiences—eating meals together, playing games, studying—Hiroki began to notice new sides of Reina…

The demons that are rampant in modern society threaten people’s lives.
People who make a living by exterminating such demons are called “exorcists”.
Reina the Exorcist, an elite girl who works as an exorcist even though she is a student.
She discovers the base of demons lurking in the city.
Reina, who accepted her mission, decided to infiltrate the demon’s stronghold.

Our disciplinary committee is made up of three members: Misaki Saotome, the president; Reiko Toudou, in charge of student guidance; and Sakura Takanashi, the strictest disciplinarian.
The protagonist, Takashi Suzuki, has average grades, but is blacklisted by the disciplinary committee for his sloppy dress and habitual lateness.
One day, he is caught smoking behind the building by the three committee members.
Normally, he would be immediately suspended, but the three propose a unique rehabilitation program.
They decide to waive the punishment on the condition that he undergo “special instruction” in the disciplinary committee room.
However, the reality of the special instruction is that it is an excuse to satisfy the sexual desires of the three.
Takashi is at the mercy of Misaki’s high-handed control, Reiko’s sweet and poisonous seduction, and Sakura’s unexpected aggressiveness.
At first, the protagonist reluctantly follows their orders, but gradually he becomes attracted to the charms of each of the three.
Misaki’s mature sex appeal, Reiko’s seductive aura, Sakura’s innocent curiosity.
Eventually, the roles are reversed, and the three of them become immersed in Takashi’s masculine charm.
Eventually, the relationship between the four develops into a twisted love relationship.
The committee room, which is supposed to correct discipline, becomes a sexually liberated zone.
