Hey guys. Looking for a doujinshi from about/at least a decade ago. The majority of the doujinshi, including the sexual stuff, focuses on a male teacher and female student who has a strong attachment to her sensei. The last scene I remember involves a time skip where the student again calls the male lead "sensei", but he tells her to stop calling him that, leading to her correcting herself and calling him "dear". I don't remember much else, but I think the male lead after the time skip (forget if he was like this before it) had glasses and I believe the female student did wear her gym clothes (or some school clothes) during one of the sex scenes because she knew it was her sensei's favorite. Beyond all that, I can't remember much else, if I'm remembering the parts before the last scene correctly at all. All I can truly say is that it's old.
