More exposure

Sandry wriggled on the spot, seeing a class full of people, thirty boys and girls looking at her, laughing, whistling, calling out, taking photos.

"Someone help me!" she pleaded, but no help was forthcoming. Then, as she squirmed, she felt a worrying sensation on her breasts as her bra started to slip. Unable to move her arms, she could not prevent her undergarment from falling away and letting her breasts bounce free, dark pink nipples exposed, to the delight of the class, who sent up a cheer.
