Though Nakaniwa is Rika’s senior, he’s incredibly clumsy, often making mistakes and even showing up late. This time, they’re assigned a business trip together, and Nakaniwa is as clumsy as ever, but thanks to Rika, the negotiations go smoothly. However, because they’re busy entertaining clients, they lose track of time and miss the last train. With no other choice, they have to spend the night there. Unfortunately, after searching everywhere, they find only one room available, so they have to share. Back in the room, they keep drinking. The next morning, when Nakaniwa wakes up, he suddenly finds Rika naked beside him! Even more, when Rika wakes up, her attitude toward him is completely different from the day before. Rika actively seduces him, tempting him. Though he doesn’t clearly remember the previous night, it seems Nakaniwa’s cock has conquered Rika...
