A teacher's holy duty! That's what my student Kotoneka thought when she came over to my house unexpectedly one day. She had always harbored feelings for me and couldn't resist coming by after hearing that I was having trouble dealing with her presence at school. Of course, we were both teachers and students... so naturally, I tried to convince her to go back home without any problems. But during our conversation, something about the peek of her plump ass through her mini-skirt just drove me wild. Unable to control myself anymore, I took matters into my own hands and our secret relationship began that very day.
