A bright and intelligent young lady who lost her parents at an early age and lives in a place that runs an inn, was always helping out with the inn's work. One day, the situation changes completely when he becomes interested in something a customer has to say. What I found in the old storehouse behind the inn was...a number of SM goods. A hemp rope game in which a young man who knows his uncle's secret falls into a whirlpool of masochistic pleasure for the first time!
