This seems to be mid-career Paulo Colimbra. The video, from which these images are taken, is one of two that he made anonymously with a production company called Sauna Boys. The cast is simply identified as "the boys of Rio." Paulo actually makes a fairly compelling Sadist. I remember the first time I saw it, when it initially, only briefly, appeared five or six years ago. For the first few seconds of watching, I didn't recognize that gorgeous creature playing the stern top as our cheerful hero, Paulo. Someone from the company must have noticed it and had it removed pretty quickly. Such things are not meant to be free.
