Amaguri Senko is a high school girl with a cool personality (as in kuudere) and a big pervert. She openly reads porn, masturbates and isn't perturbed in the slightest at the sight of penises and such. The story centers around Senko's daily life with two male handymen working for her father's company which she also helps out with, Takamura Ryou and Sugita Kouhei. Takamura ends up being constantly sexually harassed by Senko, partially due to his phimosis dick that caught her interest, but little did he know, she wasn't joking when she bluntly said "I like you"...
