One Sunday afternoon at four o'clock. Today was the day my daughter's private tutor would visit for the first time. As my daughter and I walked to the entrance to greet her, we found a girl waiting—almost the same age as my daughter. "Hello, I'm Mao Watanabe. I'll be your daughter's tutor from now on." She said she was a college student working part-time as a private instructor. Her casual outfit surprised me, a sign of how much youth fashion had changed these days. She looked just like an ordinary university girl, instantly putting us at ease. When I brought tea to my daughter's room, I found them already chatting and laughing comfortably together. I noticed her shirt was rather thin, and my eyes kept drifting in that direction. Then, by chance, her pantyhose-covered toes brushed against my hand. In that instant, I snapped back to reality—only to find her staring at me with an unexpectedly lustful gaze.
