Short story from 70s and 80s.

[AG31]

I have a faint memory of a BDSM story from sometime in the late sixties or throughout the seventies. It featured a man coming to a BDSM venue. I remember him walking down the steps to begin, but nothing else. I unconsciously copied this opening in Twelve Maxbridge Street, but I didn't realize that till much later. I'd love to find it. There was no internet, of course, so it had to have been in a book. But it was definitely short. I was reading Anne Rice/Anne Rampling/A. N. Roquelaure at the time, but I don't find it there.
