TG Caption This: turned into a little sister

Jay was a typical guy living his high school life to the best of his ability, which wasn't high, it wasn't that he was stupid he just couldn't do what academic kids could, most people weren't expecting much from him except one, his twin sister as most siblings she was annoying but deep down they were the closer than anyone would ever be. One day were he'd done particularly bad at school he kept saying half-hearted comments, such as
"I wish school didn't exist" and " I wish I could start over"
His sister heard him rant and pushed open the door
" got a problem Jay?" She asked
"Yes a big one, mum and dad are going to be pissed" he said angrily
"I wish I could start over" he said again
His sisters eyes sparked with interest
"Here take this I'm sure it can help you"
She tossed mike a cuddly teddy bear, Jay was about to laugh, another one of his sisters stupid joke, but a soon as he caught it a jolt was sent through his body, he nearly blacked out, when he was again fully aware of his surroundings he began to change.

his short, black scruffy hair, lengthened at an incredible speed, slowing down by the time it reached his mid-back, and only fully stopping its growth when it reached his butt. Then it proceeded to change to a beautiful blond, and when the hair stopped his face started to morph:
softening and getting smaller, his eyebrows thinned, his lips became fuller, eyes larger, if you only saw his face you'd clearly think he was a girl.

As the changes moved down his Adam's apple receded making his voice increase in pitch. Going on to his shoulders they became rounder and less bulky. He kept looking in astonishment as two little mounds formed on his chest increasing slowly to a decent C-cup. The changes started to accelerate as more and more surface came in contact with the change; his body reduced in size losing any fat he had' his flabby arms became silky smooth and his legs shortened while any fat he lost from his stomach and arms seemed to fill his calfs and butt.
His genitals then shrunk he let out a feminine squeal as he became officially a girl. His sister then stepped forward and hugged him
"I always wanted a sister, but I wanted her to be a younger one"

She stepped back, another jolt went through Jay, all feminine features he had gained seemed to disappear: his breasts reduced in size making her flat chested her round butt became flat as she steadily decreased in size her hair which probably had taken years to grow also shortened going back to being neck length. Everything around her seemed larger, her mind became fuzzy it soon became impossible for her to add 10+10, and this intelligence seemed to be replaced by images of her sister....

"Come on Jess let's go play"
"Yeah! pray, pray" Jess shouted, her little baby brain attempted to say the words correctly.
"Ah who's a smart little girl? You'll do much better. You've had a new chance....
