Looks interesting. So the Sensei (uke) was a member of a S/M club but he had to terminate the membership because of his work as a teacher. He said his goodbye to his Master (seme) and asked if he could see his master's face for the first and the last time. After leaving that place and that lifestyle, he resumed his work as a teacher in a prestigious school but his Master actually a student in that school.
