From the start of video Olivia and Poly are tightly tied up and ballgagged. They struggle and crawl, tries to break the ropes, unsuccessfully.
They try again, and again, camera showes them from different views. At the middle of video Yuno comes in the frame and put both of them in tight hogtie to struggle till the end of video.
They are not there for ads or tracking, just to make the website work properly and be awesome.
