A group of topless women staged a clandestine video shoot in Columbia University's Butler Library back in November, but the yolks on you -- their intention was not to titillate but to defy you to watch to the end.

The women were participating in an art video titled "INITIATIØN," which is the brainchild of Coco Young, a Columbia University undergraduate, and Karley Sciortino, who runs the blog Slutever. According to IvyGate, the film was shot in November but wasn't uploaded until this weekend.

A description of the video on Purple TV describes it as exploring "the rituals of American Ivy League secret societies, to the point of hysteria, highlighting our culture's perception of female desire."

In the NSFW video, the women remove their tops, crack eggs on each other and then rub the yolks into the floor. A few scenes show them crawling through a hallway in their underwear, and another has them licking what appears to be chocolate off each other's backs. All the while the Tapiola Children's Choir plays as the soundtrack.

Young told Ivygate that Sciortino approached her about doing a collaboration and they came up with the idea for this video. They filmed it very quickly and discreetly on a Saturday night in November. A few students were around, and they explained that they were filming a video, but New York is such an odd place that apparently no one was really fazed. They put up a tarp to block some of the weirder parts of filming. And yes, to address concerns, they did clean everything up before they left.

One person posted in Bwog's comment section: "I ran into these girls right after they finished filming this. When I gave them a weird look because they were dressed strangely, one of them said 'We're making a film. Do you want to be in it?' I'm really not sure if I should have said yes or no now..."

Others in the Bwog comments noted how despite the nudity, this video wasn't exactly arousing (unlike the amateur porn shot in Cornell University's library in 2012). Which was sort of the point, Young said.
