(Child timeline, about sevens years after the events of Majora's Mask)
Malon sat on the milk crate she had just set down, groaning as she stretched her arms and rubbed at her aching shoulders. Even with Talon and Link's assistance, delivering the weekly milk supply to the castle was a difficult task, and had only gotten more strenuous in the past few months as her breasts had begun a rather rapid expansion, giving her double the burden her male fellow laborers had to carry.
"Looks like you could use a break" observed a familiar, melodic voice behind her. The busty redhead turned on her behind to find herself face to face with the soon-to-be Queen herself, Zelda.
"Those words are music to my ears, your Highness," she replied, standing up to curtsey, before being stopped by the princess.
"What have I told you?" asked the blonde beauty.
"Not to pay any mind to the disparity between our classes..." she answered, blushing at having made the same mistake yet again. "Let me just ask the fellas if it's okay," she started before being cut off by a hand on her shoulder.
The hand belonged to Link, who simply smiled and nodded to her when she turned her head, giving his usual "Okay!" signal. Accepting it, Malon turned back to the door into the kitchen, and tread down the now-familiar path to the castle courtyard, followed by Zelda.
Kneeling in the grass, the pair made smalltalk for a few minutes, discussing general Castle Town gossip, rating the long line of suitors that had recently come calling on the Cucco Lady from Kakariko Village, and continuing their debate about if length or width made for better swords. But eventually, the topic Malon had been anticipating all week came up, when the royal beauty asked her "How have you been feeling? Is my potion working for you?"
"Well..." came the ranch girl's reply, her face turning a shade of red to match her hair. "It's kind of embarrassing..."
"There's no need to be embarrassed with me, my dear," Zelda insisted, placing both hands on her friend's shoulders, "only Impa is watching us, and you've already shown me the results of the potion before last week's..." she said, eying the farm girl's immaculate bust.
"Alright then," Malon gave in, standing up, turning her back to the princess, and undoing her belt buckle. As her skirt fell to her ankles, her friend was treated to a face-full of her newly rounded butt, clad in the violet panties she had gifted her.
"It's beautiful," complimented Zelda, grabbing both cheeks and clapping them together in a test of firmness, which only cause Malon's blush to deepen. "May I please put my skirt back on?" she pleaded.
"Oh, certainly dear" said Zelda, embarrassed at her lack of self-control. As her friend re-clothed herself and sat back down, the princess continued the discussion. "So, your breasts have expanded, your waist has shrunk, and now your buttocks are quite taut and round. All of my potions so far have been effective, but I still have to ask, are you satisfied with them?"
"Well, I have been enjoying the attention from Link..." answered Malon, who had made a lot more progress courting her childhood sweetheart with the royal assistance, "but I'm less pleased with the burden of having these weights hanging off of my chest while I work..." she moaned, rubbing her shoulders with both hands, causing her elbows to rub her breasts together.
"I thought as much..." answered Zelda, a sly grin on her face as she snapped her fingers, causing Impa to appear kneeling beside her, holding a tray with a gold liquid in a crystal bottle on it. "... which is why I brewed this. It should increase your strength significantly..."
"Zelda, I don't know how I could ever thank you..." Malon began to gush, taking the bottle from her hands. Zelda stopped her, however, "No need, my dear," she assured her, leaning in closer, "your happiness is all the reward I need..." she finished, pressing her lips to Malon's in a tender kiss, which the redhead gladly leaned into. She had been shocked and a bit frightened the first time it happened, but as their friendship went on she started to see that it was completely innocent, just an expression of the love the future Queen held for all her subjects.
As their lips parted and the spit trail between their tongues broke, Malon popped the cork off and poured the liquid down her throat with gusto, eager to resume a happy life unburdened by her own bosom.
A tingling sensation began to rumble through her, a cold shiver running down her spine, between her legs, then up her stomach to her breasts, which she could have sworn she saw glow for a second. Nervously, she stood up, then realizing that while she still felt the presence and weight of her hearty breasts, their weight was now as nothing to her.
"IT WORKED!" she cheered, jumping up and down as her royal friend enjoyed the curvaceous, bouncy view. What Malon didn't see was the smirk growing on her face. She didn't know about the side effects yet...
