巨根で種付け牧場になる町 ～名門母娘たちを片っぱしから孕ま征服！街中の牝穴が俺の家畜になりたがる！～

The townwomen are your objects! Knock up a high class harem with your full throttle big dick!

Born to a regal estate but living a life of self-indulgence, the protagonist was disowned by his stepmother.
But he pushed back -- which is to say, thrust his massive dick -- and redefined the family business as a kind of sex farm. The grand influence of his phallus took over the whole town! Every woman’s ass lifted in ovulating, slovenly hope of getting a prod from his almighty dick.
