Momoko, known as "Momotaro," is a successful businesswoman who works for a top-class miscellaneous goods manufacturer and achieves sales results that rival men. She has a somewhat embarrassing preference for drinking syrup from canned peaches. She currently has a business plan that she really wants to pass, but it is easily rejected by her boss, who calls her a "demon." Therefore, she decides to get three handsome men, Inugawa, Saruta, and Kimura, who are rumored to be the demon's confidants, to her side. She approaches each of them, but they ask for sex in return -! ?
