She puts on the uniform

Sandry could not afford to miss this class, her reports for PE were bad enough, so with a sigh of resignation she struggled into the small outfit.

Five minutes later she headed into the hall with everyone else. But while their uniforms were loose and appropriate for physical activity, Sandry's shorts looked more like cycling wear, and rode up her buttocks as she moved. Her top had its sleeves reduced to almost nothing and failed to come down far enough to cover her stomach, leaving several inches of Sandry's most self-conscious body part, including her cute little belly button, hanging out.

The rest of the class went up in a hum of whispers and giggles, which Sandry tried to ignore as she looked over the gym, which was set up with an array of different exercise stations. When the coach managed to get the class's attention, it was explained that they would go to each station in turn to be tested on their ability at it - vaulting, running, weights, etc.

Still trying to ignore the class, and knowing she had to complete the lesson and get a half-decent mark, when the coach blew her whistle Sandry jogged to the first station.
