On graduation day, she was the girl I'd been in the same class with since freshman year. Friendly and kind, she'd always greet me with a cheerful "We're on duty together today," a thoughtful and considerate girl with beautiful handwriting and top academic standing in our class. I'd secretly admired her, but felt unworthy and kept my distance. But I knew if I didn't act today, I'd regret it forever—so I finally made my move. I took Tugumi-chan away and had sex with her for the first time in my life. However, I'd forgotten a condom, so I had no choice but to thrust inside her bare. In the end, I came deep inside her—leaving me filled with regret.
