Since the beginning of the new semester, Matsumoto had been skipping school—until he decided to join the class trip. His reason wasn't because he finally felt like returning to school, but because he was drawn to the beauty of his homeroom teacher, Miss Mami, the only person who had ever shown concern for him. Mami had always watched over him warmly, but what captivated him most was her alluring figure—especially her breasts, whose shape was so mesmerizing it pulled his gaze irresistibly. Matsumoto couldn't take his eyes off her, and before long, he began waiting for the chance the school trip would offer. On the first night of the trip, Mami appeared before him, seeing him again after so long. "Aren't you coming back to school soon? Everyone's worried about you," she said gently. Unable to contain his feelings any longer, Matsumoto lunged forward, embracing her tightly and burying his face into her defenseless, voluptuous breasts.
