Kindan No Hatemitsu, by Ryuuta, has been DECENSORED :)

Now see, this is why getting old sucks; Oliver, do you remember the name of that mangaka that this post reminds me of? It’s on the tip of my tongue, ryuuga, hyuuga, yuuga… . . . it was that one mangaka that you used to post a lot of, the most famous/known one here being the tankobon of the female teacher who moves in with the male student and pays rent with her body at first all the while helping other students with their sex lives, one chapter was about an overbearing onee-san which the student-brother & onee-san get their own tankobon later on. The teacher ends up a fast-food worker and hooks back up with the main student in the end.
