STSK-123 Cram school instructor raw sex guidance [University entrance examination course/individual guidance/passing the current job]

I have obtained a record of a cram course lecturer giving to his students in a group famous for its individual tutoring. They were supposed to be studying hard together, trusting their teachers, aiming to pass the university entrance exam, but everything falls apart. They have already given up on their dream of getting into the school of their choice.
