Meet Peter, he's 15 years of age, and stands at 5'5, and 131lbs. In his early life, despite he had some toys or that to play, he felt bored and concerned when knowing that he didn't have a sibling at the time. However that concern was coming to an end at the age of six, when he was happy to hear that he finally as a sibling, and surely he'll have someone to play, and even look after in the many years to come.
His Sibling was slim just like Peter as such, that is until that freak accident at school did otherwise and changed its life forever. There was a show at school where his sibling goes to, and it was these scientific items that had been demonstrated, using some ray devices on props to make either things grow or something else. Well his sibling had been volunteered to come up, and it was only one time when a showman had slipped something on the floor, whilst he had a device in his hands. The laser swooped past the prop that was supposed to hit, but instead it bounced off the mirror and hit his sibling instead.
Although the kid wasn't sure what was going on, whether or not if these device would effect any human with it. That it surely did, and a sibling was started to get fatter and fatter, ballooning out all over the body. Its butt and thighs were growing the most, hence that these would be the biggest part of the body being grown, than a fat belly had lapped over the thighs, while everything else was coming in arms, face and everything else that thickens the sibling. All that it continued until he weighs at a massive 700lbs and standing at 7 feet tall.
The sibling looked shocked but soon smiled in delight, saying that it was the greatest moment ever, and so that size was kept and its been like this ever since. Right now, Peter was sleeping in his bed, even that he was having a long lie, it didn't take long until he felt something on top of him. That familiar feeling was no other than his 9 year old sibling's massive, obese body, who lays right on top of him.
The question I had to ask, is what gender is Peter's 9 year old sibling?
