My student suddenly came to my house. Kashiwagi was not a bad student in class, so I was completely off guard... I took her word that she wanted me to help her with her studies at face value and let her into my house, but when my wife wasn't looking, she opened her uniform and seduced me with her bare breasts. I was so excited that I got a boner. My student had a weakness for me, and I had no choice but to submit to her. Even though my wife was nearby, we became master and slave, and I couldn't resist, so she kept making me cum. My student was gradually showing her true nature as a cheeky brat. I thought that if this continued, my house would be taken over, so I made her understand with some adult pistoning.
