JUR-778 I fell into domestic SM training. ~My daughter’s tutor disciplines my body with pain and pleasure~ Mariko Koto
“…I’ve been waiting for you, Sensei.”I requested a private tutor for my daughter, who has not been serious about her studies since entering university. After several dispatches, the last person to arrive was Mr. Kuroi, who seemed young. My daughter was completely attached to him because he was a good teacher and friendly, but I was worried about how close he was to her, so I called Mr. Kuroi over, but he asked me, “Aren’t you the one who thinks of me as a man, not your daughter?”
