お嬢様は学園の精液便所 ～寝取らせ・ぶっかけ・乱交生活日誌～

The protagonist, Kuroi Kimihito, a senior student, is the boss of a prostitution ring on campus.
He assigns female students who are unable to resist because their secrets are known to them to teachers, some students, and influential people outside the school, thereby obtaining wealth and a guaranteed future.
The person who makes the protagonist the boss is
Reina Kareizawa, the daughter of a large company president.
One night two years ago, the protagonist ambushes Reina and rapes her,
obtaining a photograph of the incident, which he uses to submit her to the prostitution ring on campus, and
he has received the support of the men who flock to her body, which has brought him to his current position.
The protagonist has been forcing Reina to prostitute herself to influential people, solidifying his support, but
the anti-protagonist faction has begun to make a comeback.
Since she only has one partner per night, it seems that those who are impatient with waiting their turn are being drawn into the anti-protagonist faction.
The protagonist, who was forced to take urgent action to protect himself,
has Reina serve as a partner to more men and begins to secure new pawns.
