29 minute video. Beautiful ground work in this video and schoolgirl cosplay. This is a video recording from the legendary “Kinbiken” held by Nureki Chimuo in September of 1986. Kinbiken was the “Bondage Beauty Study Group” which ran in Tokyo for nearly 15 years (1986-2000). These videos are being made available by special arrangement with the organizer of kinbiken and we are very happy to be able to offer them in the west for the first time.
