Medical role play is pretty common in BDSM and particularly in femdom. It’s a natural fit with the dominant female authority figure and all those invasive and potentially painful medical treatments. Everything from needles and catheters through to straightjackets and dental gags have been appropriated into the kinky domain.
Most femdom medical imagery is pretty fetishistic, with lots of shapely nurses brandishing random medical equipment and staring into the camera. For example, this kind of shot. Pretty but not all that scary. For really disturbing kinky medical themed images it turns out the fashion industry is the place to look. Specifically this shoot for Interview Magazine by photographer Steven Klein featuring Karolina Kurková and Crystal Renn.
Apparently it draws heavily on the institutional white trend of Spring 2012 and features such designers as Jennifer Fein, Stella McCartney and Dolce & Gabbana. It’s certainly one of the most fetishistic and BDSM heavy fashion shoots I’ve ever seen. I’m guessing they must have hired a professional bondage rigger for the ropework shot. I think if a photographer for somewhere like Kink.com had come back with these images they’d have sent him away with the instructions to come up with something a little less fucked up next time.
