Joe walked into the house, followed shortly after his sister, Kate.
"God damn, school sucked today!" Joe said, throwing down his bookbag off his shoulders. He took off his long sleeve shirt and kept on
his undershirt, a tight shirt he knew showed off his impressive muscles.
"Couldn't have said it any better myself." Kate agreed. She flopped down on the couch next to her brother, and unbuttoned the top
buttons of her blouse, showing off more of her generously sized breasts. "My god, it's so hot in here!"
"Damn," Joe said, "You're right!". He stood up and took off his pants and T-shirt, leaving him in just his underwear, showing off his large
bulge. "Oh, sorry, hope you don't mind the view, Kate."
"Aww, it's fine. In fact, it's a smart idea." She said, taking off all her clothes except her panties and bra. However, it did nothing to
quench the heat both of them were feeling.
"Eh, fuck it, I'm stripping" Joe said, taking off his underwear. Kate soon followed, stripping down to nothing. After a couple of minutes, a
breeze came through the house, cooling them both down. The breeze picked up exponentially, and it soon felt like a storm was breaking
through the house.
"What's going on with this weather?" Kate shouted at Joe. Joe, however, wasn't paying attention, and Kate soon saw why. She could
feel her feet bones stretch and widen under her skin, and she noticed that Joe's were doing the exact opposite, shrinking and becoming
more dainty.
Joe tried to call out to his sister, but his call turned into a gasp as he suddenly shrank several inches. He would be exactly the same
height as his sister, but her legs changed, too, stretching to match Joe's previous height. He watched his legs as the hair and muscles on
them shrank into his body, and looking up, he saw Kate's legs had suddenly grew massive amounts of curly, dark brown hair, and firm,
toned legs.
They both soon realized what was happening to them, and they both screamed in shock as their hips changed, Kate's becoming less
wide, while Joe's exploded out of his body. Looking behind, he saw his butt begin to inflate, become much larger and wider, and he turned
to look to see Kate's doing the exact opposite, becoming smaller, but still firm.
Joe's chest began to distort, and soon became very shapeless, as did Kate's. Suddenly, however, Kate's breasts began to shrink into
her body, and she panicked, grabbing desperately at them and her shrinking and lightening areoles. Her chest and arms then began to fill
with muscle, growing until she had a well-defined set of abs, large pecs, wide shoulders, and very large arms. Looking up, she saw that
Joe's nipples had begun to darken, and soon, his chest began to inflate, becoming two very large breasts on a very shapely body.
Both of their faces began to burn as they changed shape, Kate's jawline becoming more defined and wide, while Joe's cheekbones
raised and cheeks puffed out. Their faces had become mirror images of one another.
Finally, both of their crotches began to itch, and their insides burned, as each of their reproductive organs changed to represent their
new bodies. Joe's penis and balls quickly began to shrink and thin, the pubic hair disappearing, until nothing was left but a tiny slit of a
vagina. Kate saw a small penis head poke out, followed by a tiny ball sack. She tried to cover it with her hands, but they quickly outgrew
even her new larger hands, and she had no choice but to release the now very large penis, with an appropriately large pair of testes.
Suddenly, the wind and heat stopped, and both of them stood dazed for several minutes. When they finally became unfazed, they
stared at and inspected each other for several minutes, before screaming and running to their individual bedrooms.
