[ENGLISH-SUBTITLE] TPIN-078 A girl who was a student 5 years ago has become a gal and is now my sex friend. My student and I are still in a sex relationship even after 1825 days!

"Teacher! Teach me how to study!" It was with that single word that my inappropriate relationship with my student began. After a student life in an environment where I had no contact with women, I became a teacher at an all-girls school, where my workplace, of course, was filled with girls in classrooms. At an age where there were no men around, the girls saw me, a teacher, as an "older man." Thinking that I had finally reached the age where I was popular for the first time in my life, I entered into an inappropriate relationship with my student and enjoyed our after-school rendezvous. Since then, many things have happened between her and me, but even after five years, there has been no change in the fact that she and I are enjoying our sex friends relationship again.
