Who are you picking at the snack bar?

I've never been so curious about the actual context of one of these photos lol. 1 and 2 look to be having a legitimate friendly conversation. 1 and 3 are half wearing bottoms/underwear? 1 is holding something (keys?) in her hand. I'm not sure if they're actually eating or just posing, but the latter seems more likely given how picturesque their food looks. The ceiling is quite low, probably a basement. Are they posing for a photo for a college girls in a bowling alley porno, and this is between takes?
