Jennifer stared belatedly at the neatly folded pile that was her gym kit. Of all her lessons, gym was the one she detested most by far, and it was in this uniform she'd spent dozens of miserable hours huffing and puffing around the hall with the rest of her classmates, trying fruitlessly to keep up. Although there were other chubby kids in her class, she was least fit by far so even they left her behind after a while.
Still, there was no way out of it; she'd tried skipping gym before, by pretending to be unwell or injured, but Ms Carroll always saw straight through her clumsy lies. There was to be no escape...
Reluctantly, Jennifer began to change into the kit, stripping down into her underwear as all the other girls in her class did the same around her. As she squeezed out of her tight school skirt, she glanced around at the other kids in the changing room. Although many of them weren't exactly skinny, none of them were as chubby as her. Jennifer didn't notice that of course; she was just checking she wasn't, as so often happened, getting left behind. Indeed, despite her corpulence Jennifer shared her mom's delusion that she was just a tad pudgy. Even when it was obvious she was the fattest in the room, like now, she was blessed with blissful ignorance.
In any case, she had to put on her kit. She grabbed the top and pulled it on, then tried to adjust it so it was comfortable. That, however, was impossible; it was at several sizes too small, and though the fabric was quite stretchy it was strained to its limit over her swollen belly and developing chest. It was uncomfortably tight no matter how much she tugged or shifted, the thin fabric clinging to each roll and fold of her expansive midriff.
Eventually giving up on trying to get the top comfy, Jennifer turned her attention to the shorts. She tugged them on with some difficulty, for although they were elasticated they were so undersized that the waistband was painfully tight anyway. Sighing, she rubbed at where they were already beginning to chafe, wishing that her kit would just fit for once; all the other kids' were fine, why was hers too small? The top wasn't even big enough to cover her belly, leaving a slice of pale fat visible between the two halves of her kit.
She followed the rest of the girls out of the changing rooms and into the gym hall, feeling her top already beginning to ride up with the movement. She tugged it down again irritably, and looked around. There was a big pile of bright plastic ropes in the centre of the room, all tangled together in a rainbow coloured heap.
"Looks like we're doing jump rope then." Said a glum voice in Jennifer's ear. She turned and saw her friend Katrina standing just behind her.
"That's not too bad." Said Jennifer. "I'm good at jump rope."
Katrina looked surprised.
"Really? I thought you hated all exercise."
"I just hate getting out of breath." She said. "I don't hate exercise on its own."
"But won't jump rope make you out of breath?" Pointed out Katrina, frowning.
Jennifer was stumped.
"I... maybe? I guess so."
"Well, I don't like any exercise, tiring or not." Stated Katrina boldly.
"I can see that, young lady." Without a sound, Ms Carroll had appeared directly behind the dark haired girl, eyes flashing menacingly. Katrina jumped half a foot into the air, then span around to face her teacher.
