SAME-030 Perverted students fuck pregnant teacher

Airi got married a year ago to a fellow teacher, but she was unable to get pregnant. She then returns to being a teacher, only to discover that her husband is in deep trouble with a troubled student: Yuki Yudzuru. Yudzuru filmed evidence of the husband fighting with a student and used it to blackmail Airi into having creampie sex, which would have solved her pregnancy problem.
