Yu is an office worker and is about to get married. Her manager is a hateful, incompetent person who always sexually harasses others. But then, one time, she accidentally made a mistake in the contract. Luckily, the manager helped her, but on one condition: she had to go play golf with him. And before that, he would teach her how to play. While teaching Yu, he touched her all over her body. Because he helped her, Yu let it go. When it was time to play golf with a partner, after finishing a round, Yu went out to rest and drink some water. Unfortunately for her, the manager had mixed aphrodisiacs into the water. She gradually lost control of herself and let him trample and ejaculate inside her. But her body was addicted to this feeling of pleasure. Even though she hated the manager, she wanted him to fuck her more. And then, she always looked forward to going golfing with the manager. Every time that occasion comes, the manager will give her special training sessions before the golf session takes place.
