This clip from 1995 shows people engaged in S&M. A fair amount of spanking is shown. A film crew is recording the entire event, which explains the presence of several cameras and a hanging boom.  

Begins with a man wearing a short skirt, slapping a woman with a leather whip, as she pleasures him. 

A large woman uses a paddle to spank a skinny white man who is bent over, tied up, and wearing black tights. 

Lastly, in preparation for an S&M session, two Asian women blindfold an Hispanic-looking man and tie him to chains that hang from the room's ceiling.
