Due to stress, she shoplifts at a convenience store and is caught by the manager, who demands that she "pay the damages with her body!" and rapes her. After that, the shoplifting incident is reported in a weekly magazine, causing a big fuss at school. In order to settle things down, the teachers expand her anus with fingers, anal beads, and vegetables, and when her tight hole is loosened, they insert their dicks!
