Irving Klaw’s Riding the Human Pony Girl (1950s) is one of the earliest cinematic explorations of pony play fetishism. The short film features intricate bondage, light spanking, and girl-on-girl pony riding, showcasing the era’s experimental approach to erotic cinema.

Midway through, the two dominatrices pause to adjust the submissive’s arm positioning, leaving viewers to speculate whether this was a deliberate artistic choice or an oversight in staging. The elaborate leather harness, wrist restraints, and face mask add authenticity to the scene, reflecting Klaw’s attention to fetish aesthetics._{View on Archive.org}

Irving Klaw had this loft and he was acquainted with an awful lot of strippers… His mode of operation was that he would take these separate segments, one with me, and one with Betty (Bettie) Page, and all these other girls, then he would splice these together until he had enough time, fifty minutes or whatever, and make what he would call a full picture…a bunch of segments of ten or twelve different girls doing their various acts… He’d piece them together in several different movies.
