I heard a rumor about the popular signboard girl at an okonomiyaki restaurant in Tokyo—apparently, she's actually quite horny. The tip came from another girl working part-time at the shop. Her name is Kurashina Sayaka, 22 years old, a skilled D-cup beauty. Acting on this intel, I decided to go undercover inside the store. Just as rumored, the signboard girl was a cute, 21-year-old, airheaded girl. Even during work hours, when I brought up sexual topics, she didn't get angry at all—in fact, she responded with increasingly wild answers. As I spent more time closely interacting with her, our relationship gradually deepened. After closing, during the after-work drinking party, the mood heated up, leading to even more explicit developments. She flashed her big tits, then we secretly met at a love hotel... What will become of my relationship with her?
