How Yuzuki made me submit - From today, I'll call you "that" instead of "uncle"♪

In a certain country, there was a prince possessing a special sperm known as the "seed of God."
Any woman impregnated by this divine sperm could give birth to a child with overwhelming magical power.
…This special sperm caught the eye of the succubus king, and one day the prince was abducted to the land of the succubi.
If the prince's sperm were to be scattered among the succubi,
many succubi with immense power would be born, and humanity would be dominated by them.
The prince vowed to protect his beloved people, vowing never to ejaculate.
To mock the prince, and to select a succubus worthy of bearing a special child, the succubus king declared the holding of a competition.
The name of the competition was the Wedding Battle Fair.
The nine succubus princesses who ruled the succubus kingdom were chosen as participants.
The prize: the right to become engaged to the prince.
The rules of the battle were a battle-fuck contest where the prince and the demon princess would make each other orgasm.
The demon princess's victory condition was to become pregnant with the prince's child right there in the ring.

The naughty female fighters mercilessly try to seduce and exploit the hero!
Don’t give in to the temptations of the evil organization, and reap your enemies!

Ishidou Narumi, a student attending a rural all-boys' school, spends his noisy but enjoyable days with his slightly ditzy best friends.
He has a "secret" that he has not made public.

In this all-male school is a popular, gentle health teacher named Mitama, who seems to be the human embodiment of healing.

Another one is Aya, his homeroom and chemistry teacher, who is feared because of her sharp eyes and strict attitude, but is also popular because of her model-like appearance.

As the only ladies in a school with no female students, these two women and Narumi have a "special" relationship that they do not tell anyone about.

Although they act respectable at the school, it's all just a facade. The truth is that one is a spoiled, no-good Oneesan, and the other is a timid worrywart born with a bad look in her eyes. Since he happened to know those sides of the girls, Narumi has developed a particularly close relationship with them.

However, they were still teachers and student. No matter how close they were, there was a line they would never cross. But the situation changes drastically when an enfant terrible named "Patricia" enters the picture.

Patricia (aka "Patty"), arriving as an English teacher, falls in love at first sight with Narumi after a certain incident. Being a bundle of energy, Patty quickly makes a move on Narumi (in a naughty way)...
From there, his relationship with Mitama and Aya begins to change.

Who will win this sudden battle?

Mitama, the pampered Oneesan?
Aya, with the face of a wolf but the heart of a rabbit?
Or Patty, rushing headlong into everything like a wild boar?

It all depends on Narumi's lower half...?
