MISM-217 First throat penetration

This is a work that was edited by the throat legend Hana Kanno, who filmed the throat training video privately as the director, in order to preserve the image of the original material as much as possible. - It was a detailed record of how Hana Kanna discovered a masochist girl with zero tolerance for the throat (she's quite a hard worker) with her own hands, and how she used her unique sense of smell to discover it.
