It had been a month since I started dating Rika-san, my senior at work. It was our first date in a while. At first, I didn't feel anything special, but when she stood before me, I naturally became aroused. She took the lead as she always did, speaking dirty words to turn me on. The more she teased me, the more excited I became. As I looked at her, I realized she wasn't putting on her usual workplace demeanor—instead, she was revealing a completely different side of herself, one meant only for me.
