Asian teacher boots and feet worship humiliation

This Vietnamese teacher has a lot of students here in Prague, mostly tourists who want to visit Vietnam and need to know some basics, but some are more accountable than others. And Jack is really not the smartest nor most accountable one! He's always coming late, he doesn't study vocabulary and his grammar is sloppy at best. And Sun, his teacher, has enough of this! The only thing that works on this guy is to punish him, make him worship the teacher's boots and feet. That's the only punishment severe enough for him to take it more seriously. He has to worship her Asian feet and lick those boots she walks in outside. And when she decides he's punished enough she allows him to sit at the table and starts to test what he has learned since last time. And it's no surprise it's almost nothing. He has learned nothing! Sun is really mad now, so she puts her feet on the table and for each wrong answer Jack will lick her soles and suck her toes. That will teach him a lesson!
