無双の孕ませオナホ騎士団　～強い牝を淫紋術で屈服させてエロ酷いことやりたい放題の絶対忠誠ハーレムを作る！～（Musou no Haramase Onaho Kishidan ~Tsuyoi Mesu o Jutsu de Kuppuku Sasete Ero Hidoi Koto Yaritai Houdai no Zettai Chuusei Harem o Tsukuru!~）

A world where beautiful and strong female knights fight for supremacy.
The main character, a meager knight, has his home country destroyed by the knights led by the sadistic female knight Carla, and ends up wandering into the forest for his life.
However, there he encounters a magic sword that turns his desire into power!

"I want to crush the female knights, impregnate them, and turn them into onhaoles"

The protagonist, who has acquired the power to make his desires come true, carves lewd marks on the female knights with big breasts and big butts from all over the world, starting with the exiled princess knight Erica, one after another, and makes them submit by impregnating them with creampie.

The protagonist, who has been sworn allegiance by the Onahole Knights, becomes the master of one of the world's greatest powers and rises even further.
