A teacher working at a certain prefectural school makes a one-off AV appearance on Sunday! He makes his debut in broad daylight in a MM van parked in front of the school building. He's a strict clergyman on weekdays, but as soon as he gets turned on, he turns into a slutty woman who gets turned on even in full view of the outside! And then, a story about his time as a new teacher leads to an emotional reunion with a special student and forbidden sex!
