Taken (Pixiv Fanbox)

Exposing shy or proud trainees is a wonderful way to break them by humiliation. There’s not much worse than being stuck in a metal frame and having your rear exposed. This trainee right here has been turned into a human statue, with his body forced into a very uncomfortable position. Everyone passing by is invited to toy and play with him by either taking advantage of his extremely slippery, lubed-up hole, his open mouth or by using various toys lying around. He especially hates being teased and edged, which is why his trainer left him with some super fine brushes to be used on his body~
