ADN-274 [Uncensored Leaked] On a typhoon night, I was left behind at school with a student until the morning... Natsume Iroha

A major typhoon occurs once every few years. I thought I'd go home early today, but before I knew it, it was already the usual time. The trains were suspended, the roads were flooded, and I ended up having to stay the night at school. Then, "Teacher, what are you doing out at this time?" Utsumi, a student, was also left behind at school. Alone in the spacious school building until the morning, the two of us were about to embark on a dangerous and lewd night.
