When Ota first joined the company, he was helped by his senior colleague Mina. Mina always kindly guided Ota, helping him progress and become a good employee. She often took Ota on business trips with her so he could learn more from her. One day, she accidentally found out that Ota had a girlfriend, who was also a colleague in the accounting department. Feeling jealous of losing Ota, Mina decided to win him back, making him love only her! To achieve this, Mina called the hotel to cancel Ota's room, forcing him to share a room with her. She used the company's ban on office romance to make Ota obey her. First, she made him massage her feet, then move on to her thighs and buttocks. Finally, she used her seductive body to entice Ota, making him have sex with her and ejaculate inside her repeatedly!
