Daddy is Big!

A dull middle-aged man, Takagi, has been fired from his company and is sighing alone in a park. Then, suddenly, a scream is heard from the nearby bush. How, isn't a beautiful girl about to be raped by two men! Takashiro, who has a pestle and a 2nd dan in karate, chases away the men, but another girl who appears there strikes him in the crotch and faints. Before he knew it, four beautiful women were looking down at Takagi in a luxurious room for some reason. What the hell is going on? Takagi's strange life begins!
