Josh and Kelly Clark were a rare example of Irish twins -- siblings born within a year of each other but not as twins -- but despite their closeness in age the brother and sister shared little if anything in common.
Growing up in the southern suburbs of the South Australian capital of Adelaide Josh and Kelly, raised by their divorced single mother Leonie, were polar opposites. University student Josh, the older of the siblings, was always extremely health conscious and sports minded, working out daily and playing the sports of Australian Rules football in winter and cricket in summer. He stuck to his ultra-healthy diet and exercise program rigidly, and the handsome 19-year-old was rewarded with a fine physique that made many a young lady's panties damp when he passed by, exercising with his friends or by himself.
Josh's iron self-discipline, ambition and rigid ways were reflected in other areas of his life too. His room was spotless, not a single thing out of place, and he never shirked on his studies either when he was at school and now at university, where he was studying sports science. Josh hoped his degree would assist him in helping rid Australia of its growing problems with obesity and inactivity, things he could not abide. The part time job he held to finance his life and studies was at a sporting goods store in an Adelaide shopping center, where young Josh was a star salesman.
Kelly, who had turned 18 in December and graduated from high school, was a completely different matter. Kelly was not a straight A student in school like her brother, far from it. She hated studying, and would only do it after much cajoling from her long suffering mother. Her report cards were mainly full of C's and D's, and upon leaving high school her main ambition was never to study again. She had a part time job in the supermarket in the same shopping center where her brother worked, and when leaving school simply increased her shifts. Leonie tried to talk her daughter into getting at least some type of formal training, but stubborn Kelly was having none of it.
At home, Kelly was lazy and a bit of a slob, having a messy and disorganized bedroom with clothes chucked on the floor, not only there but in the bathroom too. Kelly would drink the last of the milk or juice and put the empty carton back in the fridge for her mother or brother to deal with. She would leave plates, cutlery and glasses behind herself unwashed, which failed to impress her mother with Leonie liking to keep a tidy house.
It would have been utopia to neat freak Josh had Kelly only left dirty dishes behind herself and wet towels and clothes on the bathroom floor after she showered. The house was a small house, three bedrooms and one bathroom which the mother, son and daughter all had to share. And every four weeks without fail Josh would see the evidence that Kelly was on her period -- if his sister's crappy mood wasn't enough evidence of this -- when she left her packet of sanitary pads on the bathroom vanity in full view because she was too lazy to put them away out of sight. This got on Josh's nerves no end, as he wanted to see zero evidence that his younger sister was menstruating.
The only consolation was that apart from the unwashed dishes thing, Kelly wasn't dirty. She showered usually twice daily, wore deodorant, brushed her teeth, never failed to flush the toilet after she went to the loo and her used period pads were always disposed of in the wheelie bin outside during her time of the month. But considering how inconsiderate and lazy Kelly was most of the time, these were small consolations indeed.
Even in looks, Kelly and Josh were not alike. Both siblings had brown hair, but Josh's short hair was light brown much like their mother, while Kelly's long hair was dark brown like their father's hair. Josh's eyes were brown like Leonie's but Kelly's eyes were blue. Josh had a more olive complexion, while Kelly's skin tone was fair. Josh was tall at six feet, Kelly much shorter at five feet four.
While relatively dissimilar in height, it was in girth where the Clark siblings differed most. Josh was a poster boy for a healthy weight, his fit body having plenty of lean muscle tone. As for Kelly, well Kelly was as usual the complete opposite of her older brother.
Always chubby as a child, Kelly's weight problem began to escalate more from age 10 as she started to go through puberty. The teenager gained more and more weight throughout adolescence, reaching the weight of 104 kilograms by the time she turned 18, 230 pounds or more than 16 stone if measuring her weight in imperial rather than metric. She weighed 32 kilograms more than her 72 kilogram older brother, and was getting close to doubling the weight of her mother, the slim Leonie weighing just 58 kilograms.
Kelly naturally had big breasts -- even if skinny like her mother and brother the teenager would still need a D-cup bra to keep her massive mammary glands in check -- but big boobs did not account for Kelly's excessive weight in other areas of her young body. Like her chubby legs with massive thighs, her flabby upper arms, her enormous bottom and the rolls of fat that could be found around Kelly's hips and her midriff.
Kelly's fat stomach had led to her being mistaken for being pregnant on several occasions. One young boy on his way to school stood up for her on a crowded train saying that she needed the seat more than he did. A young female ride attendant at the Adelaide show attempted to prevent Kelly getting on a carnival ride by pointing out the sign that pregnant women were not allowed to ride. And in the city one day an old lady told Kelly that she was sure to have a girl as she was carrying low.
Like the rest of Kelly's body her face was also chubby, but it did not diminish her looks as Kelly was a very pretty girl despite her weight problems, and actually quite stunning facially. The clothes Kelly chose to wear did not flatter her figure, the teenager favoring low-cut jeans, denim shorts, short skirts and dresses and frequently active-wear leggings despite Kelly doing no exercise aside from walking to the refrigerator. Kelly's tight jeans and shorts would create a muffin-top around her tummy, and as the teenager always wore cotton full-brief panties -- sometimes called 'granny panties' -- as they were more comfortable for her fat bottom, the tops of her knickers would show above Kelly's jeans or shorts. However nothing looked so out of place as Kelly in a bikini, her favored attire when she went to the beach.
In something of a paradox, while Kelly's fashion sense was most unflattering to a girl of her size, she was actually pretty enough to get away with it. An unattractive girl as overweight as Kelly could never carry off the skinny girl clothes Kelly wore.
While Kelly was not fat enough for it to cause her too much adversity in life -- she would have no issues fitting in a plane seat and apart from a ride attendant mistaking her for being pregnant, no issues getting on a ride at a carnival or theme park -- to be so overweight at just 18-years-old and only months out of high school it was a concern just how big Kelly would become in coming years. Her mother and her doctor had spoken to Kelly about her weight problems and bad diet -- Josh had not because Kelly would not take it well to put it mildly -- but Kelly did not listen.
For one thing, Kelly had a posse of enablers -- her female friends -- who were just as fat as her with the same bad eating habits, and several of the girls even fatter. Also weaning Kelly off the foods and beverages that caused her weight problems would be a huge challenge.
