Almost twenty teenaged boys, from 10 to 15 years-old, were attending Master Jia's class. Their skills in Kung Fu were ranging from poor to decent. The oldest boy, Thomas, was even skilled enough that he was only a few months away from earning a black belt. There was also a single girl, Shannon, 10 years old. Shannon was the youngest child, and she was usually paired with Cinna who was only a couple of years younger. But that day, neither Jia nor Cinna were there, even if the two young Chinese women who were standing behind Mistress Tyonna looked familiar.
The students were all wondering why Master Jia was not their teacher that day, but they had too much respect for the dojo to ask this question directly. And the teenaged boys were all too happy to have three sexy young women wearing nothing but these short training gi that were barely concealing their voluptuous bodies. But the training was so intense they couldn't daydream about having sex with one of the sexy teachers. After 30 minutes of training, Mistress Tyonna asked all the students to attack the teachers at the same time. Despite their superior numbers, the boys were quickly defeated, as Cinna, Jian and Tyonna dodged or parried all their feeble attacks. Only Thomas managed to land a punch in Jian's torso, exposing her right breasts. This punch caused a stream of warm milk to jerk out from Jian's breast to Thomas' mouth.
"Let's have a break!" ordered Tyonna. "In the next room, there are refreshing drinks for all of you. You deserve it. Thomas, Jian will give you a special training. Same thing for you, Shanon, Cinna will take care of you."
Shannon and Thomas stayed with Cinna and Jian in the main room of the dojo while the other boys were following Tyonna to the room with the refreshment drinks. Cinna and Jian removed their top, offering their breasts full of milk to the two students who were fascinating by the massive mamaries of the two amazons. Thomas, who had already tasted Jian's milk, opened his mouth wide to receive more of the white liquid that would transform his body. Shannon, who had understood that her friend was all grown-up, told Cinna: "You are so beautiful! I want to be like you." Cinna gave her milk to Shannon, triggering the young girl's changes.
Shannon felt her body growing older and becoming stronger; small breasts formed on her chest as she experienced some kind of an accelerated puberty. Her face and skin color changed as she became Chinese. Her mind also changed, as she assimilated her new race's language and culture. She also began to feel sexual attraction, but not to any of the boys who were coming back to the main room. Even Thomas, whose face had become very cute and feminine, was still too male for Shannon's taste. Shannon was instead lusting over Jian and Cinna's perfect bodies.
Mistress Tyonna declared that the break was over, and that Shannon would fight all of the boys, one by one, from the youngest to the oldest. The boys laughed at the idea that Shannon could defeat them, but the girl quickly proved them wrong. She defeated her first five adversaries in about 15 seconds each. She was stronger, faster and more agile than the boys of her age, and Shannon was only growing older and becoming better at Kunt-Fu as her transformation continued. Shannon managed to deteat all her adversaries with a painful kick in the groin. But after a while, the fight became harder. The boys she had to fight were older, but also ... androgynous. They had longer hair, softer faces and some of them even had small breasts. But Shannon continued to win the fights, until there were only 5 undefeated 'boys' left. These 'boys' were already changed by the transformative drinks. They had B-cup breasts, a feminine face and body frame that was more than half-way to an amazonian physique.
Mistress Tyonna said that the 5 reminding 'boys' should fight Shannon all together. At that moment, Shannon's transformation was over: she was a 18-years-old Chinese amazon, who looked like she could be Cinna or Jian's sister. She was 5'9 tall, she had a muscular but very feminine body with large hips, a narrow waist and voluptuous G-cup boobs. And her name was no longer "Shannon Lang", but Shuang Chi. As a young Chinese woman and a proud Kunt-Fu practitionner, she will let those 5 american 'boys' to best her in combat. Luckily for Shuang, the 'boys' were still confused about their own transformation. They didn't know if they should be proud or ashamed of their B-cup breasts, their mind were still rejecting their own feminity and they were not ready to give up their boyhood to fully become Amazons. But even they were weaker than Shuang Chi, it was 5 against 1 and Shuang could not dodge or parry all of their attacks. Shuang took one hit, twho hits ... The third hit was a violent punch in her face, stuning her.
But before the "boys" could defeat Shuang Chi, another Amazon came to her rescue, knocking out one of the "boys" and attacking two others with a combo of rapid kicks. Shuang Chi looked at her savior: she was a Chinese-american amazon, taller than her, with perky D-cup boobs. Her blond hair and blue eyes were maybe the only clue of this girl's old identity.
"Thank you, Thomas" said Shuang using the mandarin language without thinking about it.
"You're welcome. By the way, my new name is Zhong-Ru" replied the young half-Chinese woman using the same language.
Shuang and Zhong-Ru fought the 4 remaining "boys" wile protecting each other. Once they were all defeated, the two chinese Amazons looked at the students: all were still lying on the floor, their hands on their crotches, but not because of the pain. The "boys" were all exploring their new pussies, and while they masturbated, their body changed according to their new gender.
Seeing all their former comrades being turned into women made Shuang and Zhong-Ru wet. They looked at each other, happy to have won together, and both felt a connexion. Zhong-Ru loved Shuang's dark hairs and bright green eyes, and Shuang was attracted to the mixed-race Zhong-Ru. Of course, they both wanted to be in a relationship with a fellow Amazon. Shuang and Zhong-Ru shared a passionated kiss while they removed each other clothes. They lay on the floor and they start a 69, pleasuring each other's pussy with their tongue.
Mistress Tyonna encouraged the other students to do the same: "Now you all have pussies, it's time for a new physical exercise. Choose a partner and pleasure her until she climaxes at least three times." Cinna, Jian and Tyonna joined their students in their lesbian orgy, and soon even the dojo's walls could not prevent people outside to hear loud female moanings and screams of pleasure until the end of the class period.
