"Takeshi is such a reliable boy." When Masumi learned her teenage daughter Mei had started dating Takeshi, her childhood friend whom she hadn't seen in five years, she couldn't help but feel joy as a mother. A few days later, Mei brought Takeshi home. Watching the two greet each other warmly, seeing how much Takeshi had matured, Masumi's eyes sparkled with quiet realization. Then, she saw it—the unmistakable bulge in his pants, his thick, fully erect cock pressing forward as he moved toward Mei. That overwhelming presence stirred something deep inside her, and from that moment on, there was no turning back.
