"Stretch outside, shrimp," Carmen pointedly scoffed, plugging her nose at Stacy, who had recently returned from her own morning run. "Hell, you actually kinda smell like a shrimp right now, too."
"Oh, at least I can stretch," Stacy giggled. "Only things you can stretch out for is a bottle of wine and your legs at frat parties."
"You know me so well, little sister," Carmen playfully grinned. "Jealous?"
"Why in the world would I be jealous of you?" Stacy laughed.
"I have friends," Carmen answered.
"Well, I have integrity," Stacy retorted.
"You two get along in the strangest of ways," your mother, Tracy, remarked at your sister's rivalry from the kitchen as she made some food. "Anything you two would like for breakfast while I'm here?"
"Pancakes, please!" Stacy beamed.
"Would you like some pancakes, too?" Tracy turned to your older sister.
Carmen rolled her eyes and puffed out her chest. "No, thanks, I'm doing keto right now," she flicked her parted, blonde, bangs. "I'll take a cheese keto omelette with onions and spinach."
You mother stroked her chin. "And how does one make this keto omelette?"
"It's literally just a regular omelette, Mom," the younger sister groaned at Carmen's pretentiousness. "Keto means that they can't eat carbs."
"Really?" she gasped, in disbelief at the idea of her middle daughter never eating her mother's homemade pancakes ever again. "W-what would I bake for your birthday, then?"
"Woah, woah, woah, I can still eat 5 grams of carbs. I bet if I don't eat 5 grams for, like, two weeks it'll be fine to eat a slice of cake," Carmen defended.
Stacy cocked a brow in skepticism. Tracy, on the other hand, was relieved her daughter would still try her baking.
Carmen sat down on the couch on her phone and noticed the golden bowl on the coffee table next to her. "What's up with this bowl?" she remarked to Stacy, who was heading upstairs to shower. Something about the bowl caught her eye.
"Maybe Mom got some new china," the little sister shrugged from the stairway, looking down from the rail.
"Mom! You get some new china?" Carmen called out.
"A little busy!" Tracy called back to her daughters. "But no, I didn't!"
"Why is it just laying there?" Carmen wondered. She picked up the bowl and felt the ornate etchings. "Is this... gold??" she gasped.
"Wait, what!?" Stacy yelped, rushing back down. "Are you sure?"
"Unlike you, little sister, I'm pretty confident I know my jewelry," the older sister's brows furrowed.
"Why is a golden bowl just mysteriously laying here?" Stacy hopped down from the stairs in wonder.
"I have no clue," Carmen grinned. "But you thinking what I'm thinking?"
Carmen led Stacy to the college-aged girl's room that had turned into a guest room when she moved, one which she had always reclaimed whenever summer break came around.
"Something I've always, always wanted to try was to drink wine from a literal gold glass with a friend," Carmen beamed giddily. "This'll have to do," she gestured to Stacy and the bowl.
"You sure I won't stink up this precious room of yours, dear sister?" Stacy snorted at her sister's dream.
"Oh shut up and help me knock this off my bucket list, 'kay?" Carmen laughed.
"It's probably Dad's since Mom didn't know about it," Stacy worried about using it without permission.
"Don't worry," Carmen reassured. "Gold is, like, the most stable chemical. It can't corrode, so there's no way he'd no, and no reason he'd be mad at us! Just let me grab some wine," the older sister dug underneath
"Uh, okay," Stacy gulped. "Y-you sure it's cool if I drink that?"
"Relax, Pinot Noir is non-alcoholic," Carmen lied. She poured the wine into the golden bowl and smiled before taking a sip. "Ahh, is this what being rich feels like? It tastes marvelous... and kind of like cherry?" she mused.
"Uh, really?" Stacy stuttered as she was handed the bowl, taking a quick gulp herself. She tasted the cherry flavor, but it kind of tasted.. a little yucky and burned her throat. She started to feel a little dizzy. "Hey, you sure that didn't have--"
----
"--alcohol?" as she finished her sentence her vision started to clear and Carmen suddenly looked way younger.
"Did..." Carmen stammered. "Are you wearing my clothes?" she pointed at the blouse in front of her.
In response to the peculiar question, Stacy looked down, and instead of her sports, her gaze was met with a rather sizable chest compared to her normal one. "W-what?" she jerked back up to Carmen across from her. Her sister's hair was tied up in a ponytail, and was a dirtier blonde, unlike her typical fairer, blonde locks. Her hair... it looked like Stacy's! She was wearing her running outfit, too! "What in the world did you make me drink!??" Stacy cried out, examining her taller, softer, and much more curvy, developed frame.
"It was just wine, I swear!" Carmen stared, feeling her acquired midriff, which felt so much tighter than her own tummy, Stacy being very toned unlike her own body. Carmen was skinny herself, but in a more natural, never worked out kind of way. Having everything so tight and her chest not bounce at all... it was an odd experience for her at her developed age of 22.
"We've switched places! I have your body!" Stacy panicked, her reality of logic collapsing right in front of her.
"I've noticed, little sister," Carmen took a deep breath, remarking of how light and energetic she felt. 'Maybe I do have a drinking issue or something,' she grinned to herself. "Or perhaps that's big sister, now?" she joked, effortlessly standing up and seeing the room from her now couple inches shorter height made everything seem off. "Woah, feels kinda... bouncy..." Carmen muttered, reconsidering her overly casual workout routine. Carmen naturally had a thin yet curvy figure, so she jogged on average once, maybe twice, a week. Stacy's body provided what seemed to be an endless source of energy that made her feel more... awake, thanks to her intense daily training.
Stacy resigned to using her arms to push herself up instead her usual legs-only squat to thrust herself from the ground. "It feels pretty bouncy in here, too," she chimed in, wincing at having felt her larger breasts jiggle in recoil as she stood up. "If we really swapped bodies, then that had to be the weird bowl, right?"
"Must have," Carmen cupped her sisters relatively small B-cups through Stacy's body's thin sports bra, barely believing the scenario that unfolded between them.
"Wh-why are you feeling me up?" Stacy rubbed her new eyes, guffawed at her older sister's actions.
"Sorry!' Carmen rose her hands in her defense. "Been a while since I was as small as you, shrimp! I'm honestly surprised you didn't immediately fondle my tits yourself, considering how much you've stared in envy at it before," she mocked.
"I'm not jealous, and I'm not small!" Stacy growled. "I only stared because you wear the weirdest fucking things to my band concerts and track meets! All the trumpet players came in at the wrong time because they were practically drooling at you," Stacy complained.
Carmen laughed, remember to jut out her chest and gave a seductive wave to Stacy's classmates during her sister's clarinet solo, causing them to completely ruin the song when it was their cue. "Ahh, that was funny... Don't worry, though. Compared to Mom and Erica, we're both tiny anyway."
Carmen cleared her sister's throat. "In all seriousness, why don't we stay like this for a bit?"
Stacy's jaw dropped. "You make fun of me all literally the time, but now you want to live as me?"
"You're too sensitive, little sister, us older siblings have a responsibility to toughen up the younger ones," Carmen smirked. "As for why I'd even bother being you? Summer vacations can get boring for me since all my friends have moved out for school or work, and most of my high school buddies that are still around are out out of touch or working normal lives. "With this, we could both freshen it up. I can temporarily re-enjoy my teenage years goofing off before junior high starts back up again. Maybe we keep it a secret as a game, even."
Stacy blinked at the proposal. She and Carmen often did not get along, but the younger sister was definitely lying when she said she wasn't jealous. Stacy had a scrawny build. She was ecstatic when her boobs had finally reached a B-cup this past year, but so far the growth spurts seemed to have stopped. Meanwhile, Carmen, while not as top-heavy as the eldest sister, was blessed with ample C-cups, ample curves, with large hips, thighs, and prominent ass. Carmen pulled off the vixen look that practically hypnotized her classmates both in band and track. "I-i--" she murmured. "I dunno..."
"You always make it sound like you don't care, but," the older sister cocked an eyebrow. "I haven't seen Linda come over since the summer vacation two years ago. I could smooth things over with her. I remember she started getting into the popular crowd."
Stacy gulped.
"I could get you a boyfriend. A loyal one. I'm experienced, so just tell me a name, and I'll have them ask you out," Carmen grinned. "I could make you popular. Just like how I was," she whispered.
