For disobedient children, the method used by the instructors of the University of Su is - as long as they are not practiced to death, they will be fucked to death!The practice is hard, but the heart is lost. "Report to the instructor, you are deliberately torturing me!" "Love is deep, abuse is ruthless." With a shrug, the instructor of Su University used his strength to let someone know what real "torture" is.Note: The main CP is the rough guy instructor attacking X the tough student is subject to the deputy CP A pair of instructors who are always fighting each other + a pair of bunk couples who bully and are bullied Sweetness: cream sandwich biscuits.Sadness: one-nth of the balsam pear rind.
