18+ Kyokon de Tanezuke Bokujou ni Naru Machi: Meimon Oyako-tachi wo Katappashi kara Harama Seifuku!

The women of town are his objects! He'll Knock up a high class harem with his full throttle big d*ck!

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 d*ck -- and redefined the family business
as a kind of sex farm. The grand influence of his phallus took over the whole town!
Asses of every woman lifted in ovulating, slovenly hope of getting a prod from his almighty d*ck.

For him, the wealthy baron of Breedville, a dream life of climactic impregnation begins HERE!
