HKD-108 Pink Abacus Cram School Fundoshi-sensei's Extracurricular Class Yoshiho Saki

While running a coffee shop, Yoshiho Saki also has an abacus cram school. And I give one person a secret private lesson in an extracurricular lesson. Even though I am an abacus teacher, I have the same libido as people, and I cannot help diverging it. That is why the number of applicants for enrollment was always endless.
