Jim realized that he had only one real choice. He couldn't spend the rest of the night as a kid since he needed to meet up with Rick behind the school to reverse the spell, and he couldn't do that if he was constantly being shooed back into the classroom with the other kids everytime he tried to sneak off. Being caught by Mrs. Moore was also out of the question since she would most likely drag him into the principal's office in front of a group of middle-aged teachers (bad idea) who would either be wondering how he changed into an adult in a matter of 10 seconds (if the spell allowed them to notice him change) or why an adult was sneaking around a high school dance (if the spell brainwashed them into thinking he was always the person he changed into). Jim didn't know either way how the spell would work so he had to be discreet in how he got changed.
Jim looked at the group of attractive girls walk down the hallway and shuddered.
"Oh well," thought Jon, "It looks like I've got high heels and tits in my immediate future."
Jim walked briskly from the cafeteria doorway towards the group of young girls conversing with one another. He tried to walk past them as inconspicuously as possible to avoid arising suspicion from them, which was hardly necessary since the teenage girls were too absorbed in their own conversation to notice the underdressed teenage boy (Jim was still dressed in his blue jeans and t-shirt that he was wearing before his trip back in time) run past them.
Jim gauged that he had just gotten within 10 feet of the group of females when he suddenly felt a powerful tremor go through his body. He was greeted with the sensation of every square inch of his body rebelling against him as each appendage of his contorted, grew, contracted and shifted on it's own. Jim felt his dimensions change as his body shrank in height causing his point of view to shift closer to the ground, only to rise up again as he felt the heels of his shoes elevate. He felt the fat deposits in his body move underneath his skin, migrating away from his midsection and extremities only to be gobbled up by his now ravenous chest, hips, and buttocks which swelled from their feast. The fat deposits in his chest had Jim's full attention as they ballooned outward growing softer as the fat depostis turned into breast tissue and more sensitive as the nerve endings inside rewired themselves, making his chest officially an errogenous area. The newly formed breasts were then enveloped by soft material that pushed upward and outward on the new extremities, as the top of Jim's shirt receded to proudly put his cleavage on display. The rest of Jim's clothes contracted against his body and shrunk in length as they merged together and made a single blue dress that hugged every newly developed curve on his body. The comfortable sneakers that he was wearing were now totally replaced with high heels that put a strain on the arches of his feet and the dirty pair of socks that he was wearing were now a delicate material that creeped up his legs and under his dress to form a pair of pantyhose. Jim noticed that the changes were increasing in speed as his hair shot out of his scalp and fell behind his back to form a nice, well kept mane of hair while his nose shrunk, cheek bones rised, lips blossomed, ears became pierced by two matching earrings, and a layer of make-up plastered his overall face. Jim no longer felt like himself at all, every part of his body was brand new, with the exception of his penis which seemed too stubborn to give in to the spell and stood it's ground. But this wasn't to last as his last trace of manhood retreated into his body, giving him an orgasmic feeling that flowed throughout his body. The receded member flowed into Jim as it unfolded inside of him and formed his ovaries, uterus, and other inner plumbing indigenous to females. Jim felt a pop of air blow past him as the smell of perfume greeted her nostrils, signifying the end of the spell's conversion. Although it felt like the process took a full minute, in reality it only took a quarter of a second. So fast that the lead girl of the group talking hadn't even finished the syllable of the word that she was in the middle of when the transformation began.
Jim opened her eyes and immediately looked down. Most of the changes weren't in view to her at that angle due to her "flesh melons" obscuring her field of vision but it was more than evident that he was now a her. A quick discreet brush against her crotch confirmed that her underwear only contained a hole instead of a pole.
"I'm going to have one helluva time explaining to Rick how I ended up like this," thought Jim, who blushed at the thought of meeting up with his friend in his current condition. Rick always loves the sight of a great pair of tits. The question was how would he react to his friend, that he loved to aggravate, now that he was a she and had a set of her own. "I'm not worried about him refusing to change me back, because I'm one-hundred percent sure he will change me back....eventually." Jim took another gander at her perfect body, that seemed to have been culled from the best qualities of the girls she passed and mulled over her situation. "Oookkkaaayyy, I might have to agree to go on a few dates with him before he changes me back. I simply can't imagine him passing up this type of situation where he can have some fun at my expense."
Remembering her present situation, Jim took a quick glance behind her to see
if anybody had noticed her sudden sex change. Half expecting to see Mrs. Moore, the restroom bound girls, and the kids in the hallway looking at her with a mix of shock and wonderment, she was instead pleasantly surprised to see that no one in the hallway was paying her any attention.
"Thank God," thought Jim, "At least something is going my way."
Jim turned around and proceeded to walk down the hallway, a simple action before that was now made a little more difficult by her new center of gravity, the high heels that replaced her sneakers and the "junk in her trunk" that she found impossible not to sway back and forth while she walked.
And so the "new girl" at the dance slowly made her way down the hallway trying to figure out what she was going to do next. Totally oblivious to the fact that, despite what she thnks, her transformation didn't go unnoticed.
