I didn't have any friends, so I liked spending my after-school hours reading in the library. There was always a quiet girl there, seemingly plain and reserved, who happened to enjoy the same books as me. After that, we started meeting regularly in the library after class. She appeared shy and unassuming, but in reality, she had a voluptuous, curvy body that stood out. She loved books—and confessed she was also crazy about dirty talk and erotic topics. Spending time with her became the most blissful experience for me. I couldn't hold back any longer once I felt the pressure of her big tits and tight pussy. "Maybe around an F-cup...? What do you think?" she asked bashfully, yet revealed her deeply horny, aggressive side. Those days with Mizuki became something truly special for me.
