"Two nude Latinas are making out."

Half an hour of the three-hour photography seminar has passed.

Lily’s still not sure whether or not she’s a lesbian. She’s on her hands and knees, naked, obediently lapping at Ki’s wet pussy. The curvy mohawked girl lies on her back across a featureless white cube, gasping and moaning as two more lesbians kiss and suck her nipples.

A cute ginger-haired tomboy who, it has to be admitted, looks a bit like a punkier version of Sophia Lillis kneels behind Lily, wearing a big green strap-on. She thrusts deep into Lily’s own trembling pussy, making her pant with bliss, fucking her senseless in front of two dozen rolling cameras. A black woman with close-cropped hair grabs hold of her hair and forces her face down into Ki’s pussy, plunging her tongue even deeper into the other girl’s wet depths.

On a chair in the corner, two nude Latinas are making out. In the other corner, a Chinese girl with short spiky hair is masturbating with a pink dildo while she gazes longingly at a pretty blonde in handcuffs, who’s being groped and tickled by a girl with dreadlocks and mocha-coloured skin. Finally, an Indian girl with a ponytail stands on a stepladder above the whole production, pert bare bottom presented to the audience, under strict instructions not to move.

The photographers dart around the tableau, hunting for original angles, looking for the best possible way to capture the captivating subject. Dr. Mungus sits in a corner, watching closely, taking notes.
