We're all familiar with episode 13's grand double cleave-gagging as well as minor bits like the pole tie scene in episode 14 and handcuffing in episode 24, but here is one that went unnoticed. Real shame it was Kazumi and not Jun in this outfit and situation, especially strange considering they're both models at this point. For anyone wondering it is just a photo shoot, no actual kidnapping.
You guys honestly have no idea how long it took me to make that stitch picture. Usually the camera just goes straight down but nope! Here they had to swing it side to side! The subtle changes are unnoticeable when the camera is moving, but upon stacking the frames up it goes beyond tedious especially when the video source you get it from insists of having a giant play button right in the center!

Had to shop the sides with the expand tool, the right top corner is probably the most obvious indication. Maybe tomorrow I'll use my tape gag template to complete the picture, but I am too tired.
