I need to locate a video based on description below

I am looking for a Japanese video that I watched a few years ago based on how I describe it if possible as I cannot find it anywhere. The video starts by a Japanese schoolgirl being in school and within the gym changing rooms. Then some male students come and grab her from the changing rooms and take her to the classroom. All the students including the male teacher who is bald then begin undressing her and using vibrators all over her body. They then have a gangbang within the classroom.
