I've been looking for this doujinshi in where there is a Trouble maker student who usually don't go to school and had low grades so the School nurse talked to the student and he opened to him in which the student slowly fell in love with the school nurse that he wants to be petted , spoiled etc. then the student became jelous because the school nurse is getting close to the other female teachers in the end the student confessed his feelings and the nurse gave him a footjob and inserted a cotton swab on his di*k while doing that.
Sorry I'm really being too Informative since I read this last year ago ...
