Caught in a sudden torrential downpour, a group of schoolgirls takes shelter under the eaves of a building, where they are approached by an "uncle" who runs a hot spring inn. He seems like a kind man, offering them towels, snacks, and even the use of his open-air bath, but is he actually a rapist!? The man's hot, boiling cum is released in large quantities inside the chilled schoolgirls' vaginas! "Please, don't cum inside!"
