Minami Shirakawa, a married female teacher who has achieved her dream of becoming a teacher, shares a room with the vice principal during a pre-trip for the school trip. She is attacked while sleeping and resists, but she cannot help but feel pleasure from the sticky sexual acts that are unique to those who have an endless job of mastering academics and passing them on to future generations. In contrast to her husband, who is indifferent and extremely rational in both work and sex. For two days and one night... the married woman's Kokoro burns with sex over and over again, but she never leaves the trip. This is the 14th installment of the immoral series that you can never show to your students or your husband.
