Rino Yuki has been his fuck buddy for a year. Just as he prepares to confess his feelings, she announces her marriage to his boss. He assumes their affair is over, but she whispers that his cock still feels best and continues fucking him inside the company where her husband works. They grope her huge tits and have sweaty sex in cramped storerooms, conference rooms, and the office during overtime. To avoid evidence, they always fuck raw, and whenever they are alone at work, immediate penetration is the rule. They ignore their jobs and keep having creampie sex, unable to quit the dangerously addictive affair.
