I got engaged to the daughter of my boss at work and was blessed by many people, but I had a secret that I couldn't tell anyone. In fact, for the past two years, I've been meeting up with my colleague Emi several times a month for a sex friend relationship. Even after Emi told him that she was engaged, she didn't change her attitude and continued to see each other for mutual pleasure. Today I went on a one-night, two-day hot spring trip with Emi, and to be honest, I think it's time to end this relationship... but I can't let go of the pleasure I can't get from being a boxed-up girl's fiancée.
