SGKI-007 - Prefectural Ingahara [Piston Vibe] Girls' School

I closely interviewed three female students attending a school in the ninja village, known for its special classes. It's an extracurricular lesson called 'The Lesson of Endurance.' "As a ninja, you sometimes have to act like a doll to pass by enemies when infiltrating enemy territory. Therefore, no matter what, you must not 'move' or 'make a sound.'" This training tempers the mind to resist revealing information under torture. Intense climax occurs during piston vibration, Acme bicycle use, and sex with the teacher, but they are scolded with, "Don't leak! Will you leak information even in enemy territory?" Their immature bodies endure with trembling lower bodies due to continuous vaginal spasms! What is most lacking in modern society is the 'ninja' spirit.
