On The Night Of The Typhoon, I Was Stranded At School, Together With A S*****t, And We Were Alone, Together... Iroha Natsume

A massive typhoon that comes once every few years. I thought I'd go home early today… but before I knew it, it was the usual time. Trains suspended… roads flooded… In the end, I ended up having to stay overnight at school. That was when it happened. 'Teacher… what are you doing at this hour?' Student Utsumi-kun was also stranded at school. Alone together in the wide school building until morning, a dangerous and lewd night was about to begin.
