The Pregnant Maids Who Serve Only Me ~Five Women Devouring Sperm

The protagonist is an ordinary boy attending an academy.
Sullen and always alone, he is shunned by everyone, male and female alike.
Living with only his mother in considerable poverty, he sees not a shred of hope for the future, and his days remain endlessly gloomy and gray.
Then one day, his stifled life is turned completely upside down.
On his way home, a luxury car suddenly pulls up in front of him, and a beautiful stranger steps out, flanked by several bodyguards in black, and speaks to him.
Beauty: "I've come to pick you up—Lord 'Seedbearer.'"
Without delay, they forcibly take the bewildered protagonist to a grand mansion.
Facing the utterly confused protagonist, the beauty—"Kousaka Iyo"—reveals a shocking truth.
This is the villa of the president of the world-famous company "Tenkuin Trading," and that president, "Tenkuin Yoichiro," is none other than the protagonist's biological father.
The protagonist's mother was once a maid serving the Tenkuin family, and after sleeping with Yoichiro, she became pregnant.
Though she was ordered to abort to avoid any future trouble, she flatly refused and left the mansion.
The baby boy born after many hardships was the protagonist.
The protagonist, who until now knew nothing of his biological father, is utterly stunned.
Iyo then explains why the protagonist has been brought here.
The president's heirs have met with misfortune one after another, and the family has no successor left.
President Yoichiro is advanced in years, and having a new heir is now next to impossible.
Therefore, despite being a rather shameful illegitimate child, they have chosen the protagonist—Yoichiro's own flesh and blood.
Protagonist: "So, you're saying... make me the heir?"
Iyo: "No, that is not it. If you were to become the heir, the group would rapidly collapse—so predicts our company's AI, 〈Demeter〉."
Protagonist: "Huh...!? Then what exactly do you want from me?"
Iyo: "We want you to produce an heir."
Maids have already been arranged for the protagonist at the mansion—the meaning being that he is to sow his seed in them and produce an heir.
Each of the maids harbors unspeakable circumstances of her own, and all are strictly ordered to obey the protagonist's every command.
Iyo: "Demeter predicts... that if you have children with them, excellent heirs will be born, and the group will flourish even more."
Iyo: "According to the prediction, we recommend that you embrace them."
Though being treated as a stud is unpleasant, having beautiful women at his mercy... such a golden opportunity must not be missed.
And so, the protagonist, who until now lived out his days in gloom, makes full use of the status he happened to obtain, thoroughly enjoying a decadent, blissful life of sowing his seed in the maids.
