You're 22 years old and studying at Kigiora University. You thought your university life would be normal and bland, but what no one else in the school knows is that you're a secret mega-masochist and you're in a secret BDSM relationship with the secretly mega-sadistic, sexy, 203cm tall, big-breasted, 28-year-old Professor Yuna. After her daily lectures, the two of you go to the empty storage room where your sensei/girlfriend mercilessly teases and bullies you, but you love it, because the only thing that can match Yuna's sadism is your masochism.
