Luna is an Omega who has just changed to her new job in a first-class company. On her first day of work, she suddenly comes into a strong "heat" that she never experienced before. It was a gentleman who saves her from her tough situation. The only thing that can be done to stop the "heat" temporarily is by sex with another and when he touches her, it feels like electricity runs all over her body. His thick and long fingers stir her inside and make her so weak that her juices drip all over the floor. Even though it is first time meeting him, why does it feel so good?
