Jessica sashayed her way to Gender Studies as she prepared herself for her first day there. The head cheerleader was confident that this new class would be but another easy A course like a handful of her other classes. She wasn’t exactly the brightest in the building, but she still needed the grades if she didn’t want to feel out of place with her peers. And even if she received an F, Jessica could always find an opportunity to fuck whoever teacher it was to win them over. The golden blonde slut found a chair to sit in with a few of her friends just in time for the bell to ring. Once she sat down, Jessica noticed a large machine in front of all the desks.
“Strange,” Jessica commented. “What is that doing here?”
When the teacher, Mr. Nivea, entered the classroom, he was wearing a hazmat suit. That’s so odd; none of her teachers’ introductions were like this. Why couldn’t he have put his casual clothing on instead? Once he got near the machine, and the other students got to a seat, the teacher made a gesture to tell the teens to be quiet.
“Students, as you all know, this class is very new, so you have no idea what to expect,” Mr. Nivea announced. “But believe me when I say this class will change your lives and your outlook on the opposite gender forever,” he briefly paused. “As we’re going to use this device to flip your biological sex for a whole semester!”
“What?” Jessica exclaimed credulously. “You’ve got to be kidding me!”
Everyone else was just as stunned as Jessica. Cheerleading practice was coming up, and the last thing she wanted was something that would ruin her chances of being successful. She saw most of the other students ridiculing the teacher after what they heard from him.
“Don’t listen to that weirdo,” Jessica’s brown-haired friend instructed. “What he just said is a joke.”
Jessica pondered for a few seconds about what Mr. Nivea said. Why would she ever believe someone she scarcely knew? “Now that I think about it, there’s no way he could be serious. After all, that kind of strangeness only exists in TV Shows and movies!”
“Well, let's get this class started,” Mr. Nivea said. He then flipped a switch from the machine. In no time, a strong white light enveloped the entire classroom; that instantly triggered Jessica’s transformation.
Jessica skyrocketed in height, going from a petite 5’2” to a commanding 6’4”. Muscle mass began protruding from her arms to help them grow. They started from her biceps and then progressively went down from there. It was only a matter of time until Jessica’s triceps were also thick with pure strength. She watched her forearms follow suit, and her hands bulged as they became meatier. Each polish from the cheerleader’s nails was erased. Jessica’s behind tightened as her buttocks turned compact. Her thighs followed suit, with her new muscles infiltrating them. The cheerleader’s calves embraced the same muscle mass settling into them, and then body hair decorated her legs. Jessica’s feet elongated from a delicate size 7 to a broad size 11 while her toenails abandoned their polished trait.
Jessica’s wavy golden blonde hair, which she cherished for years, was next on the chopping block; it withdrew into her skull and remade into a short, smooth quiff. Her eyebrows thickened with hair while her eyelashes did the opposite. Jessica’s forehead became broader while her blue eyes sank to her skull and narrowed. Hair began sprouting from the bottom of her face. She initially just had sideburns, but they reached her sharpening jawline and got closer to each other until they united around her now rough lips, coating her chin while they were at it.
Jessica felt a lot of pressure on her neck after the changes reached it. Her neck widened to help orient her developing Adam’s apple. “What the?” she blurted. She was shocked at how deep it had become. Of course, her transformation wasn’t over yet, so plenty more surprises were to come for her.
Jessica’s prided D-cup breasts melted into her chest. Pieces of fat inside it were obliterated one at a time. Her hardened nipples similarly shrank down and darkened, her areolae decreasing in circumference. Eventually, Jessica’s boobs ceased to exist, leaving her with the chest of an eleven-year-old girl. Her bra never felt so vacant on her chest. It abruptly tightened when muscles superseded the fat in her chest, creating a pair of powerful pectorals. A mild portion of chest hair rose while the transformation went down to Jessica’s midriff. Her vague set of abs became a defined six-pack as her feminine curves straightened due to her narrowing hips. An additional thin line of hair conjured from the bottom of her navel and plummeted to her growing pubic hair; that signaled the final stage of Jessica’s changes.
Jessica’s clitoris stretched out of her cunt as it touched her panties. At first, it was a slightly comfortable one-inch clit, but the more it grew, the tighter her underwear got. Jessica’s pussy rapidly sealed itself when her clit was between two to three inches long. Jessica’s clit was at four inches, but its growth spurt was only halfway done! Jessica’s clitoral hood morphed into her foreskin after her clitoris hit six inches. Her clitoris finally developed a head at the end, stopping her clit’s growth and confirming its new role as her penis.
Jessica’s internal organs began shifting around as they oriented to her new frame. Her labia progressively drooped down to help some of her new organs. Jessica’s cervix closed, and her fallopian tubes plummeted to become her vas deferens. Her uterus withered into nothingness, but then it regenerated into her prostate. Jessica’s egg cells ceased production to make way for her developing sperm cells. By the time her new testicles finished forming, Jessica’s underwear could barely contain her new manhood.
Once the white light vanished, Jessica and her classmates took their time figuring out what just happened. What Jessica discovered when she looked down at herself was something that would blow her mind.
“Oh my god!” Jessica exclaimed, looking at her new member through her underwear. Everything about his new form felt so alien; there wasn't a single remnant of his previous self. What was once a body befitting of a cheerleader was now entirely remodeled into one similar to the football jocks he had been rooting for! He looked over to his friend next to her, who was just as shocked as him. But unlike the new hunk, his friend got unlucky and became a hideous pig.
“Oh, you’ve got the worst of it,” Jessica stated, clearly grossed out at what he was seeing.
“I know,” his friend answered. “How am I going to survive months being a fat guy?”
Their shock quickly seethed into outrage when they looked at the teacher responsible.
“Wow, I can’t believe this.” Mr. Nivea commented with astonishment; it also leaned over to fear because of all the choleric faces he was seeing from some of his students. He informed his students anxiously, “Okay, class, we expect you all to write a detailed diary on your day-to-day life as the opposite gender.” He paused for a few seconds. “Oh, and there are vouchers for clothes to get at the mall.” That was the last thing the teacher said before he grabbed the machine and hastened out of the classroom.
“Unbelievable,” Jessica muttered as he got out of his seat. His red and white cheerleading outfit was absurdly tight on his frame, and he hated it. There were even tears all over it because of the overwhelming muscle. He went to the teacher’s desk to get his voucher. While he was getting that, Jessica noticed a new name written on his voucher picked just for him. He read it, which listed his new name as Jeffery.
After putting his voucher on his desk, Jeffery considered everything that could happen while he was like this. Nearly everyone he knew would mistake him for a stranger. Sure, he looked quite handsome, but even that wouldn't be enough to mitigate whatever damage had been done. Jeffery thought of ways to cope with his new body. Maybe he could try what it’s like to be on the football team after purchasing new clothes. Since he was attracted to girls and guys, the himbo could also try to have a homosexual relationship with his boyfriend.
But regardless of whatever the new hunk thought of, he knew one thing: this would be one arduous semester.
