Hinatako plots to make her beloved teacher her own. The normally strict teacher forgets that he is married and succumbs to Hinatako's seductive voice whispering in his ear. After school, the two go to the teacher's house, where his wife is not present, and there they greedily seek each other out, immersing themselves in sexual pleasure. Hinatako's lust goes even more out of control as she tries to steal the teacher from his wife and make him her slave.
