Seasonal Trip

"Did we really need to wake up this early to get filled with sand everywhere?" Carla whined to her older sister, already dreading the heat wave that was going to melt her into a goth puddle the moment she stepped out of the protective sanctuary that was the AC inside her sister's car.

"Do you really need to complain this much, this early Carly?" Mel asked her sister without taking her eyes off the road, looking over to find a spot where to park. "It's not even 10AM! Chill sis, you'll have fun!" She beamed at Carla a big smile, trying to appease her younger sis.

For her part, Carla wasn't having any of it, rolling her eyes at the mention of her childhood nickname. If their parents hadn't practically ordered her to go with Mel to the beach, the goth could have spent most of the day inside the beach house, venturing out only during the night.

"It's easy for you to say," Carla said, glaring at Mel. "You are built to withstand this horrible horrible season, me on the other hand? I can't wait for the chilly winds of Winter that will bring me back my beloved hoodies."

"Bluuurgh, Winter is so gloomy." Mel grimaced, as she parked her car in a good-enough spot. "Everything is so gloomy and dead, it depresses me."

"And that's why it's so good!" Carla quickly answered back, bracing herself to walk out of the car. "Bundled up on the couch with a cup of tea? What else could you a-AAagggh...!" A groan of displeasure escaped the younger girl's mouth as soon as the hot wind slapped her across the face.

As they walked side to side together, Carla's words held some weight. The two sisters couldn't be any more different.

If Mel was a ray of sunshine, Carla was a snow cloud just waiting for the season to end.

Mel looked like the textbook definition of a beach babe: golden tan, long sandy blonde hair cascading over her shoulders, and a body that was almost meant to be admired under the sun. She had tied her flowery towel around her waist like a skirt, her red bikini top making her already big bust pop out. She even carried a large, stylish beach bag filled with all the essentials for a perfect day in the sun.

Carla, by contrast, stood in stark opposition to her sister's Summer aesthetic. Dressed in a black one-piece swimsuit with a loose and oversized white T-shirt that was as pale as her skin, covered it. Her dark hair was pulled up into a messy bun, already dreading the inevitable battle against sweat and humidity. Unlike her sister's sun-kissed curves, Carla had a softer, more petite build. Her body was made for being bundled with layer after layer of clothes rather than flaunting skin.

"If I die of a heat stroke, I promise I'm haunting your ass." Carla huffed annoyed, carrying their parasol under her arm.

"If you die I promise to bury you somewhere cool," Mel answered back, giving her sister a teasing smile.

While Carla grumbled and groaned, Mel couldn't be any happier. "Here! Perfect spot!" The older sister stated, finding a spot that wasn't so close to the few people that were already there.

With a long and drawn-out groan, Carla stabbed the parasol into the ground, throwing her own towel underneath and skittering inside the meager shade as soon as everything was in place.

On the other hand, Mel stretched her arms high above her head, taking in the sun's warmth with a satisfied sigh. "See? Isn't this nice? The sound of the waves, the breeze, the sight of the seagulls stealing a distracted guy's fries," she said pointing at the bird robbery taking place a few meters away. "Summer is just perfect."

Unable to disagree any harder, Carla folded her arms, frowning. "Perfect for roastery chickens who enjoy slow-roasting in their own sweat."

Mel rolled her eyes, kneeling down to set her things up next to her sister's. She didn't want to admit it, but Carla's attitude was starting to get to her nerves.

"Where is it..." She mumbled, digging into her back until she finally pulled out a sleek bottle of tanning oil. The label had been peeled off long ago, leaving only the faint outline of where the branding logo had once been. 'Something something Golden Delight.'

Mel gave it a little shake before flashing Carla her sweetest (and fakest) smile.

"Speaking of chickens," Mel said holding up the bottle, "You're going to fry if you don't put on some protection."

Carla squinted at it, suspiciously. "That doesn't look like sunscreen to me."

"Well it's the only one I have with me," Mel responded, already pouring some oil on her hands. "You don't want your skin to dry out in this horrible, horrible season, do you?"

"Uuuuuugh, fine." Carla groaned, taking off her white tee.

Mel wasted no time, rubbing her hands together to spread the oil evenly, before pressing them against Carla's shoulders.

"GHAA!" Carla flinched, still looking down at the ground when Mel began rubbing her back. "Warn me before you go grabbing me like that, your hands are cold!"

"I thought you liked the cold?" Mel just giggled, already working the slick oil into Carla's pale skin, with slow, circular massages. "Relax Carly. Just let big sis take care of you."

The oil spread easily, gliding under Mel's palms as she kneaded it into her little sister's shoulders, down her neck and along her arms. The surprisingly cold oil dripped down inside Carla's one-piece, making her shudder as it ran down her back.

Mel leaned in slightly, her voice dropping into something smoother, almost hypnotic in nature. "See? Summer's not that bad, is it now?"

Carla let out a breath, trying to not shiver as her sister's hands massaged her shoulders, in small teasing circles. "It's fine, I guess."

"Just fine?" Mel pouted, rubbing the oil over Carla's thighs, giving them a light squeeze.

The scent of coconut and something sweeter was starting Carla's senses. It was more than fine, she had to admit, but she wasn't going to voice that out...not yet at least.

Closing her eyes, she leaned into her big sister's touch, enjoying the way she massaged her pale legs, Mel's hands gliding over the exposed skin, squeezing down from the edge of her hips all the way down to the knees.

"Okay, be an obedient girl and lay on your stomach." Mel purred against her sister's ear, letting her breath brush against it. Somehow, it was even hotter than the air around them.

Carla tensed, a shiver running down her spine despite the heat. "Why do you have to say it like that?"

Mel giggled, slapping Carla's legs. "Because it's fun. Now move."

Seeing how they both were occupying her towel, Carla crawled over her big sister's, laying over it on her arms.

Mel watched closely, biting back a smirk as the black fabric of Carla's back started to shift. It didn't vanish all at once, no that would have been too obvious. Instead, it melted away in tiny, seamless changes, the material thinning and retracting at the edges where the oil had touched.

And for now, Carla was none the wiser.

Before she could realize what was happening, Mel began working her way up from Carla's legs, her fingers kneading deeper as the oil soaked her sister's skin.

Now, wherever Mel's fingers traced, Carla's pale complexion took on a darker, richer tone, like a sunbath on fast forwards. But not only that, the back of her slowly one piece turned bikini was changing colours too, alongside with the strands of black hair that brushed against Carla's back, the loose hairs taking on a tone similar to Mel's.

The older sister grinned, dragging her nails lightly along Carla's, now exposed, sides before giving her hip a playful pat.

"Okay, turn around," she ordered. "We have to make sure you're fully covered in 'sunscreen.'

Carla blinked, still hazy from the slow, rhythmic kneading of her back and shoulders. She shifted onto her back, letting out a small whimper as Mel straddle her thighs and began to pour more of the shimmering oil into her hands.

Mel patted her sister's cheek, her fingers lingering just a little too long. "Be a good girl and try to soak up some rays."

Carla grumbled but obediently stretched out under the sun, something that had never crossed her brain before.

With a smirk on her face, Mel continued to massage the front of Carla's legs, biting her lips as more womanly fat began to shape up her sister's legs.

"We couldn't do this sort of thing during Winter, could we?" Mel asked as her hands began to massage Carla's flattening stomach. Not even noticing her one piece had been long gone.

"Y-yeah, you are right sis," Carla meekly nodded, arching her back and pushing herself up to get more of her big sister's touch. "I would ne-EEK! What are you doing?"

Mel didn't waste a second, slipping her hands under Carla's bikini top to grope her breasts.

"What's wrong?" Mel asked nonchalantly, groping Mel's boobs to her heart's content. "I'm just making sure your 'sunscreen' is even!"

"Or..." Mel teased, her voice dripping with amusement, "do you want to have sexy tan lines like me?"

Mel tugged her bikini top down just slightly, just enough to reveal a strip of creamy, untouched skin and the edge of a pink little nipple.

Carla was too stunned to respond, her gaze jumping from her sister's chest to her face. "E-even it out, please..." Without much protest, she said in the smallest of whimpers.

Mel's hands continued to shamelessly grope her sister's breasts, the flimsy excuse she gave even thinner than the layer of oil covering Carla's skin.

"Hiding a body like yours under ugly hoodies is such a crime, sis! Plus, your boobs must feel all cramped and stuffed in them I bet." Mel encouraged, tugging at Carla's nipples before resuming her groping massage.

Carla's modest chest fit perfectly in Mel's hands, but as she massaged more and more, the tan spread, and more fat began to fill out Carla's breasts. The changes were subtle at first, but soon Carla's once-petite frame was becoming curvier, more voluptuous, and undeniably sun-kissed, just like her sister's.

And while Carla's body changed, her mind also was getting brighter too as soon the tan began to spread across her face.

She slowly nodded at her big sister's words. She hated feeling trapped inside hoodies, her girls needed space to breathe!

The thought of being confined in layers of fabric suddenly felt suffocating, and Carla couldn't believe she'd ever enjoy dressing like that.

With a wide grin, Mel began to caress her sister's face, her fingers gently smoothing the leftover oil around Carla's forehead, cheeks, and jawline, giving her the finishing touches to make their looks match.

"See? Isn't this nice? The sound of the waves, the breeze, the sight of the hunk guys and pretty girls playing volleyball," she said pointing at a pair that was playing together, just a few meters away. "Summer is just perfect."

"Summer is just perfect." Carla repeated absentmindedly. Looking following her sister's hand, just to see the ball bounce their way.

It rolled to a stop near their towels, and one of the players, the cute fit gal, jogged over to retrieve it.

"Sorry about that!" the girl called out, her voice cheerful as she scooped up the ball. She glanced at Carla and Mel, her eyes lingering for a moment too long on the younger sister. "You two look like you're having a great time. Want to join us? We could use a couple more players!"

Mel raised an eyebrow, glancing at Carla with a playful smirk. "What do you say, Carly?"

Carla wouldn't have even entertained the idea of playing a ball game on the beach before. Sweating was already annoying enough but working up a sweat? On purpose? That would've been unthinkable! Carla would've scoffed, rolled her eyes, and buried herself deeper into the shade, muttering something about how she would be cheering for her sister from her spot under the shadows.

But Carly...?

"Like, sure! That sounds fun, sis!" She grinned, her confidence shining through as she pushed herself up with a bounce.

"Want to make a bet?" Mel's smirk widened into a full-blown grin, playfully pushing on Carly's shoulder. "Whoever loses has to pack up everything?"

Carly gave her older sister a matching grin, "funny way of sayin' that you wanna pack everything alone!" Both sisters giggled almost at unison, both sisters checking out the other girl as they jogged behind her to join the game.
