I’m just going to link to this because I don’t think it was originally intended as porn, so I’d hate to further broadcast the smiling faces of these high-spirited young ladies on the internet in a place they presumably never intended. This looks to me like some college girls at a museum display in some dungeon or castle. One of them has gotten into the spirit of the thing and allowed herself to be strapped down to the birching bench, and another one has picked up the “for display only” birch bundle:

I first encountered the idea of a spanking gauntlet as a young reader. I’d found a pulp novel about girl gang members in some big city, who were described as initiating a new member by stripping her and making her crawl between their legs as they lashed her with leather belts soaked in a bucket of water. I later discovered accounts of various male military organizations doing something similar to discipline wayward soldiers.
Now here are a couple of stills from a 1966 Hungarian movie, showing a naked blonde female prisoner forced to run a painful gauntlet of uniformed men:
The movie is The Round-Up (or SzegĂ©nylegĂ©nyek) and the blonde is Magda Schlehmann. The plot, near as I can tell from various fragmentary sources, involves suspected guerrilla leaders imprisoned in a military fortress on the steppe. The captors do not know which of their prisoners are the leaders, but (as IMDB puts it) they know enough to apply “perfidious forms of coercion effectively.” Yup, I’d say so!

She’s good with a volleyball, but Amelia Jane Rutherford famously finds ways to be not-so-good if there’s a spanking in it for her:

And, inevitably, there is!

What does a girl’s face look like after you whip her breasts with a soft flogger? Like this, of course:
From Her First Punishment — which I very much doubt this actually was.

“Ladies, your masseur is ready for you now!” I know some of you would live at this spa, if you could only find it:
I found this on a Tumblr, but it’s actually the advertising photo for “The Strap”. In its original location, the photo has not been snipped. Nor, for that matter, has the man.
