This is a homage to the good old days Harmony video clip.

This clip starts where part2 ended. Miki and Hiroko are cross legged tied either. Nose hook is added on Miki, she moans and drools helplessly.
After they left alone, Miki untied ropes by herself, then she changed Hiroko's gag to big ball gag. Now Hiroko starts drooling behind ball gag, President of company get satisfied.
