Ten years after last seeing my childhood friend from the neighborhood, I couldn't help but be shocked at how much she had changed. Mei, who was now attending college in Tokyo, had returned home to the countryside for the first time in a while and casually came over to my place like old times. For the first time upon meeting her again, I realized just how dramatically her body had matured—she was practically a completely different person. Her plump, firm breasts were clearly visible even through her clothes, instantly making my heart race. Overcome by an uncontrollable impulse, I lunged at her. At first, she showed hesitation and embarrassment, but her demeanor quickly shifted. Soon, Mei climbed on top of me, riding passionately and grinding her hips wildly. Her appearance now exuded a mature, sensual allure—nothing like the childhood friend I once knew.
