It was picture day at the St. Margaret's Academy for Wayward Girls, and standing side by side next to each other in a row, the twenty or so girls of class of 2-3 waited patiently for their turn to begin. All were eighteen, and their slender bodies stood out in sharp contrast to the large white sheet that had been hung up behind them across the walls of the gymnasium. To any visitors who happened to be watching, the scene would have looked to be nothing more than a simple photoshoot for the school yearbook. For the students themselves though, there would be no escape until the session was over.
A slight blush here, a nervous tap there, the signs were more than obvious to anyone who knew where to look. And with this being their second year at the academy, most of the girls seemed to have already realized what was expected of them next. They stared down anxiously at the floor, unable to keep still as they waited for the signal to begin. Their only hope now was that the session wouldn't take any longer than it needed to be.
"Alright," said the cameraman, "On the count of three, smile!"
They had been practicing for well over a week now, and the moment the words left his mouth, the entire class moved as one. Together, the twenty or so schoolgirls of class 2-3 lifted their skirts up above their waists as they lowered their panties to their knees. Then, staring straight ahead with frozen smiles on their faces, they spread their legs apart and tried not to blink. The camera flashed out once, and twenty pairs of exposed privates were captured in high definition on the screen. A second flash followed immediately afterwards, and the image refreshed to show every single detail of their smooth and bare skin.
"Perfect," said the cameraman.
He clicked through the two photos, double checking them as they appeared.
"And now for the back," he said.
There was a slight pause as the girls hesitated, and then turning around to lift up the back of their skirts, they leaned forward to brace themselves against the white sheet. Bending over slightly as they thrust out their rears, twenty rounded bottoms now presented themselves as they lifted up into the air. Like this, the entire group held still, each student holding their breath as they waited with their heads bowed down towards the ground.
"Wonderful, simply superb," said the cameraman.
A third flash, and then a fourth as the screen flickered in rapid succession to show twenty pairs of naked cheeks. And of course, the privates of each girl as it peeked out from the gap in between. A shiver moved down the entire row like a wave as the girls blushed in turn from the shame. Curving up from between their legs, the tight slit of their outermost labia looked almost pristine.
