"Kids, we are out the door in five- get a move on!"

The Seols were hours away from their long-awaited and much-needed vacation, and Mrs. Seol was nervous that she couldn't hear the rolling of her son or daughter's suitcases on the floor upstairs yet. 'It's probably Sullyoon making sure she has every one of her fifteen thousand bathing suits,' thought Mrs. Seol as she checked her watch and went through her carry-on in the kitchen.

She could hear at least one of her children descending the stairs a moment or two later. It was Jae by the sound of it- at around 6'2" and 200 lbs. The solid young man's steps were unmistakable. He didn't need to pack nearly as much, just a bathing suit and warm-weather clothes.

"Rio De Janeiro, here we come!" Jae exclaimed as he rounded the corner to join his mother in the kitchen. His mother thought to herself what a handsome boy he had become, and he looked it in his sweater and jeans, though he'd need to change into something warmer when they arrived.

Jae's aunt had been suckered into one of those time-share sales pitches and ended up with a few weeks in a beautiful Rio beachfront home that they couldn't use. So when they offered a week to Jae's family, the four quickly agreed to take the vacation together. Rio de Janeiro was supposed to be beautiful in February, as opposed to the cold winter winds of the Midwest.

When Jae's dad joined his wife and son in the kitchen, it was time to yell up to Sullyoon once again, from whom came:

"I'm coming!" from Sullyoon in an annoyed tone upstairs.

Sullyoon stopped briefly and grabbed the sexy pair of black-laced panties she thought she might get to show to one of the vacationing boys she hoped to find there. Her brother would inevitably be staying out late banging some dim-witted college girls as she knew him to do; why couldn't she have a little fun?

High school boys can be so frustrating. Sullyoon had thought about giving her cherry to a boy she'd liked a few times, but they'd all disappointed her somehow. Whether bragging to their friends or treating her poorly to look cool, every one of them wasn't worth it. But it was no wonder they pursued her- Sullyoon was a stunner. She had deep brown eyes. She’s been an idol trainee for years now. Sullyoon's thick black hair looked good straightened as she usually wore it or tossed up in a ponytail as it was when she headed downstairs. Her family finally saw her rounding the corner to the kitchen, wearing tight black yoga pants and an equally tight LG Twins t-shirt over her 32C breasts.

"You don't even like LG Twins!" exclaimed Jae as his sister came into view. His eyes widened when he saw how little her outfit left to the imagination.

"Oh, shut up, Oppa!" She got so frustrated with him sometimes. He was always picking on her, and though she sometimes liked it (it was like flirting practice for boys at school or the training facility), he often got on her nerves, like he was now.

Jae couldn't help himself most of the time; she was an easy target. Plus, it enabled him to distance himself in his relationship with his sister. He often felt bad how turned on when Sullyoon's trainee friends came to visit or sleep over. As a senior in college, he wasn't supposed to find their teen bodies and their scantily clad nighttime appearances so arousing. They were close to his sister's age, and she was a battle unto herself.

Sullyoon rarely covered up when at home. Jae had more than once walked in on her naked and brushing her hair in the hall bath, causing her to jump and her tits to jiggle as she shrieked and he mumbled an apology. He was guiltily familiar with the particular shade of pink of his little sister's nipple that showed when her loose-fitting tank top had drooped during a lazy day on the couch. And seeing the sexy brunette's petite frame tanning on their deck with her bikini untied... it was sometimes too much.

So Sullyoon and her brother typically kept each other at a distance, which helped to calm some of the storms that can arise between two stubborn teens living together at home. Sullyoon's mother talked to her once or twice about being more discreet around her brother. However, it still seemed like every other morning that he was seeing her cute pussy lips peeking out at him as she bent over to put makeup on in the mirror and he swung open the un-closed bathroom door.

Once or twice, Jae had slipped into the unwitting fantasy of closing that bathroom door behind him and teaching Sullyoon a lesson or two about being naked around him, but his senses got the better of him. More than twice, he'd found visions of her swimming around in his head as he released a little pent-up steam in bed at night, but those he shook as soon as he realized their presence.

And so, Jae did as he usually did when Sullyoon's tight ass had him wound up: he pushed the thought from his head, figuring that any 18-year-old with yoga pants hugging her cheeks the way Sullyoon's did would have his cock hardening the way it now was. His hardness made another appearance on the plane when Sullyoon's t-shirt rode up as she slept against the window, looking adorable. He gazed at her flat white tummy before pulling the shirt down undetected. Brat or not, he didn't want the young guy in the next row checking out his little sister any more than he already was.

The family completed their travels about six hours after leaving the kitchen together and were tired. That long trip, cooped up in an airline seat or the back of the uncomfortable resort bus, left all four family members longing for a nap before they arrived in the early afternoon. Sullyoon was the first to go for it after they'd ooo-ed and ahhhh-ed over the beauty of their temporary home. She pulled her t-shirt over her head as she sauntered down the hallway, revealing a comfortable cotton bra that Jae's eyes couldn't miss before she closed the door behind her and laid down on the soft bed.

Jae went to his bedroom and dozed off to the image of his sister's backside burned into his eyelids: her wiry arms prying the skin-tight cotton tee off her body and the flexing of her beautiful back as she lifted her arms over her head... it simply wouldn't leave him until he was fast asleep. Even then it was Sullyoon's body that pervaded his dreams as he napped, his little sister causing his cock to stand at attention for the better part of an hour or two before:

*KNOCK KNOCK KNOCK*

Jae rubbed his eyes and let out a yawning mumble. "Yeah, I'll be there in a minute!"

"Come on, sleepyhead," squealed his sister.

Jae got out of bed and went to the door. His sister didn't seem like she would let up until he showed her he was out of bed. When he came to the door and cracked it open so light streamed onto his face, his little sister stood there at the threshold with her hip cocked, looking hot as ever. She was all prepped and ready to go, hair pulled back with sunglasses atop it, a yellow spaghetti-strap top holding up her beautiful rack, and jean shorts so short he could see the pockets peeking from below the tattered hem. She had been working on her skin leading up to the vacation, making every inch of exposed skin a magnet for her brother's eyes.

'What the hell, man!' Jae thought as he rubbed sleep from his eyes, 'We've only been here an hour or two, and you're already gawkin' your sis!' Jae had suspected Sullyoon was going to be showing off a bit when they got on vacation; she was starting to develop that curiousness that high-school girls as pretty as her did when boys were checking her out everywhere she went. He didn't expect to be one of those guys himself, but it was happening regardless. Thoughts wandering, he readied himself, and by the time he emerged, his family was already walking out the door.

"Where are we headed anyway?" Jae called after his mom as he closed the front door behind him.

"Well," she replied, "since we always wait to go into town 'til the last day, and your father and I explored the grounds while you two were wasting time napping, we figured we'd see what downtown has to offer."

Jae and his sister beamed at her suggestion; they both figured they'd be more likely to find a cute boy or girl there than at the resort. But Jae found one sooner than that; on the bus to the town's main street, a desirable-looking brunette caught Jae's eye and seemed to be sitting alone. Jae got up from his seat and approached her; he'd only just sat down next to Sullyoon, and he figured she wouldn't mind. He cracked a joke and politely asked to join her, and before long, the two of them were smiling and chatting like old friends.

Sullyoon did mind, however. Jae's new seat had left her feeling awkwardly alone. Her parents in the row in front of them were flirting in that weird way they sometimes did, making Sullyoon want to gag. Instead, she turned her head and decided to get a better look at the girl Jae had found.

'That's just like him,' she thought with a twinge of anger. But it wasn't anger that struck her as she eyed up the new flavor of the week; it was jealousy that caused her to start comparing the brunette's attributes to hers. 'My tits are better than hers,' she thought begrudgingly, her hands made their way to her breasts, feeling them to be sure. 'And she's not in shape at all,' she kept spinning. By the time they arrived downtown, she had analyzed every part of the girl without realizing it and was sure she was prettier. But then, like her brother, she had to scold herself for getting so worked up over her brother's new friend. Sullyoon thought maybe she just needed something to eat to cure her crankiness.

But her wrath didn't stop there, or at the dirty look she gave the new girl as she stood giggling with her brother as they stepped off the bus. Jae's parents were prepared to give him a minute as they checked out downtown, and then maybe let him go off alone, but Sullyoon had no such plans.

"Daaaaddd, I want to try on some clothes. Can you ask Oppa to come with me?"

"Honey, he's busy. I'm not going to interrupt him while he's talking to his new friend," her father replied. "Just come with your mother and me to this art gallery, and then we'll go wherever you want.

"No way, I know how long I could end up looking at some silly painting with you two! I'll just go alone."

"Oh no you don't, Sullyoon," he retorted immediately, but she was already headed away from him and pretended not to hear. Her father then called after her: "You can't go anywhere around here alone!" But it was no use; she was cranky, and he knew she wouldn't listen to him when she acted like that. So Mr. Seol, with a sorrowful look on his face, interrupted his son's conversation with the pretty girl and explained he'd need to run after his sister and be her bodyguard until she came around. Jae huffed and hawed, but in a few seconds, he'd agreed to meet Emily, whose name he'd just learned, and took off after his sister later that night.

"Sullyoon, wait up!" He said, as he was about 30 feet behind her. She was about to turn the corner, so he hustled and caught up.

"What's gotten into you, Sullyoon? Why didn't you answer me? I know you heard me," Jae asked as he grabbed her arm, and she finally stopped her long strides.

"Well, excuse me; I didn't think it could be you calling me. You were so busy with that skanky-looking girl you met on the bus; I didn't think you'd have found the time to come after me."

Sullyoon nearly winced as she said the words. She realized as they came out that they were a bit harsh, and she shouldn't be acting so jealous; it was only her brother, after all. She looked up at him, her eyes fixed on her feet. After that outburst, Jae didn't see a scowl as he'd expected but a hesitant smile. He knew the look well; it was always his favorite way of avoiding a fight with her. So he put on a big smile, and Sullyoon giggled as always when she realized she was being crabby.

"Let's get you something to eat," Jae said as he took her hand, and they turned back in the direction Sullyoon had been heading. "But don't think I'm going to sit around while you try on ten thousand hats like we did in Mexico."

Sullyoon laughed as she remembered it, happy that her brother had joined her and left the bimbo who'd been stealing all his attention. She didn't like to admit it, but even though she and her brother had the occasional explosive fight, there was nothing like a good laugh with him; it cheered her up immediately.

Before long, the two siblings casually rambled the streets of the admittedly dingy town, though the delicious pastry Sullyoon was snacking on was a wonder. As she felt the sugary sweetness touch her lips for the first time, she began to feel better; or maybe her brother's arm around her did it. She could see why girls liked him. He was handsome and intelligent, and he was so good at making her feel the way she did now: happy. At a sleepover one night, one of her friends had suggested that Jae looked like Won Bin, and though she'd said she didn't see it, she had probably watched every movie he'd been in twice since. Once again, she felt grateful she'd pried him away from the other girl.

So they went on, walking and talking with Jae poking fun at Sullyoon for the pockets of her jean-shorts showing and Sullyoon clinging to her brother's arm like a child. At one point, with his arm wrapped around her, Jae felt the hem of her shirt rise, and his hand fell upon bare skin. He knew he should have moved it, but when Sullyoon said nothing, he decided against it. Besides, it was an innocent touch, like the way his fingers moved all by themselves and pried at the waist of her shorts daringly. He must have just been feeling a bit turned on by the girl his sister had successfully twat-blocked him from.

They stopped in a few interesting-looking stores; Sullyoon tried on a hat at one of them to get a rise out of her brother, and the shopkeeper threw them out when they bumped into a display as he grabbed it from her head. At one point, Sullyoon convinced her brother to come into a store with all kinds of clothing displayed outside. He sighed and ducked under a low-hanging wind-chime as he followed his sister into the store. She pranced a bit, looking at this and that before going to the changing room to try something on.

Jae had his back turned when Sullyoon came out.

"What do you think?" She said as Jae turned to face her. She stood posing in the same jean shorts but an entirely different top. It looked to be knitted, probably by the woman standing at the entrance to the store, and it wasn't quite opaque. It didn't cover half of her upper body, stopping halfway up her abdomen. He could see tiny gaps in the woven fabric throughout, with Sullyoon's chest peeking at him. When he noticed the darker pink circles atop her perky breasts, he looked away.

"Sullyoon, I think I can see too much through that!" He exclaimed.

"Oh, settle down, you dog, I'll wear something underneath it, I just want your opinion."

"It looks real nice, Sullyoon," Jae assured, looking at her sideways.

His eyes stopped momentarily, and Sullyoon looked down to see what he saw. One of her nipples had found its way through the fabric and was poking through clearly. She shrugged her shoulders and said:

"Ooops, maybe you're right," she said, twitching a bit as she tucked the nub beneath the fabric and closed the door to the changing room. She felt a bit naughty revealing herself like that to her brother, but it wasn't that different from what he got at home- this time was just a bit more... apparent, she supposed.

"Alright already," she called to him, having redressed herself and emerged from the changing room. You can look now, Oppa." She gave him a snooty look and walked to the door to pay for her new shirt. Jae noticed immediately that she had folded her yellow top halfway up and under, and his wide eyes gave him away.

"Jeez, what are you, my dad?" She probed him, "It's hot out here and unless you want to see me sweating, I'm going to fold up my damn shirt."

"Wow, okay," he said, backing off. I was just worried the midriff monster had gotten to you in the changing room."

"Ugh," she breathed, leaving the store with her cute new purchase. She couldn't wait to try it on later.

They kept on roaming about until Jae finally said, "We should probably think about heading back. It's got to be two hours since we left Mom and Dad."

Sullyoon didn't look pleased, but she agreed, and they returned and met their parents. However, as they returned, something caught Sullyoon's eye. Down a side street, beyond a dark stretch of road, there was a sign that said simply "ANTIQUES," and it was probably a hundred feet from anything resembling a store. 'What an odd place for an antique store,' she thought inwardly, 'and that is the first sign I've seen in a while written in English,' her brain hinted. She felt oddly drawn toward it.

"Oppa, come on, check this out," she said, grabbing his hand and pulling him off their intended path.

"What is it now, Seol Yoona?" Jae called her by her full name.

"Look at this place! Why do you think it's so far from everything else?" she said with childlike wonder. It was cute, and Jae decided against raining on her parade, instead following her lead, even if the alley did give him the creeps.

They passed a few doors to what were probably garages on the other side and an abandoned old barber shop before they were standing beneath the buzzing, neon sign. The window panes were cloudy, and the inside was only dimly lit, but he had to admit- it was intriguing. Jae was content to just look through the storefront, but Sullyoon would have none of it, and once again, he was treated with a view of her denim-hugged behind as she pranced into the store.

"Greetings, children..." Jae practically jumped as the old woman sitting behind a very old-looking desk spoke to them. Her face was only lit by a small desk lamp, but it didn't look pretty. It looked exactly as he might have expected, like the croaking voice from her old, dry lips.

"What can I help you with, my dear?" asked the old woman in the direction of his sister.

The place may have creeped Jae out, but Sullyoon, as was her nature, seemed entirely unfazed.

"Oh, nothing," she beamed. We're just bored, and we saw your shop from way down the street."

"Ahh yes," croaked the old lady. Many years ago, this was the busiest street in town, but not anymore. Perhaps I can find something to cure your boredom, young girl. Why don't you and your boyfriend follow me?"

Jae was about to protest, but Sullyoon gave him a look suggesting he should just let that one slide. So they followed the old woman back into the shop, into a small alcove created by three enormous armoires, each with hundreds of tiny drawers. A small, square window above them cast dim light on a table directly in the center of the alcove; dust particles lingered listlessly in the air.

Sullyoon turned to her brother with an excited grin; perhaps Sullyoon had finally led him somewhere that didn't involve pastel colors or pretty beads this time. The two siblings waited anxiously as the old woman fumbled through a few drawers near the middle of one armoire.

The old woman drew three glass vials out of the drawers she'd chosen. Each held a liquid of slightly different color, with a thick, syrupy appearance.

"Bored, you say?" she asked. "Try one of these, and I promise all your boredom will melt away! Place three drops of this green elixir in a cup of tea before bed, and you'll find your dreams utterly at your control. " As she described it, she held the vial to the light, and the two Seol children found their eyes glued to it. "A touch of this red one to your tongue, and you'll find any food tastes one thousand times better, if only for a few moments.

Once again, she held it to the light, and their eyes fixed on the pearlescent appearance of the liquid. Sullyoon was positively speechless, but the reasonable side of Jae finally found himself wondering how much the old coot would charge for what was probably sugar-water as she set the second vial beside the first.

The old lady hesitated, looking down at the last vial in her hands. It was much smaller than the first two, with a pretty crystal stopper and a jet black liquid inside.

"What does that one do?" Sullyoon questioned her impatiently.

The old lady didn't answer, looking up at the two young ones before her and then back at the vial in her withered palm. "My dear, who did you say you two were again? I can be very forgetful. "

When Sullyoon didn't speak up, Jae quickly said, "We're brother and sister, and we're here with our parents, staying at a resort near the coast."

"How nice," replied the old woman, closing her bony fingers over the vial. Then perhaps I have just the thing for you." She quickly rustled through the drawer nearest her and pulled from it a vessel just like the other two sitting on the table. She put the smaller vial back in its original drawer, except she inserted a key into the tiny lock above its numbered plate and turned it to seal the drawer shut.

"But wait!" cried Sullyoon. "You didn't tell us what that one did!"

"Sorry, my dear, but this one's not for sale."

Sullyoon didn't look pleased with her answer, but when the old woman denied her access to it again as she described the third potion, Sullyoon seemed to drop it. This blue liquid could let them hold their breath underwater for up to ten minutes- one use only. Jae was starting to feel claustrophobic in the tiny antiques shop, and he needed to hurry them along.

"How much for all three?" he queried.

"Because you two have brightened an old woman's day, how about... fifty real. That's twenty-five dollars if you have it."

Jae was surprised and eagerly paid the old lady after following her to the front of the store with his little sister in toe. As they made their way to the desk, Jae saw the old lady hang the key on a tiny nail that had been tapped into the side of one chest of drawers. He hoped his sister didn't get any ideas, but when he reached behind him to grab his wallet and didn't see his sister there as well, he was almost certain she had.

"Excuse me, ma'am, I may have dropped my cell phone back there. Do you mind if I go back and grab it?" He asked politely, handing her some folded bills from his wallet. The old lady permitted him with the wave of a hand to mumble something about kids and their cell phones before rustling through her money box to make change. Jae ducked around to the back of the store in a flash, but not fast enough to catch Sullyoon before she'd already gotten up to no good.

The key was missing from its hanging spot. It was hanging from the keyhole in the drawer he'd hoped it wasn't. Sullyoon was turned away from him, holding up the flask to the light like the elderly woman had done before.

"Sullyoon," he whispered, coming to her side to scold her.

He saw his sister jump, and before he knew it, the tiny vial had slipped from her hands and crashed down upon the wooden tabletop. As soon as it landed, the liquid disappeared in a puff of fragrant smoke. It smelled... wonderful. Was that hazelnut, his favorite flavor? Or was it lavender, like the body wash he so often smelled on Sullyoon fresh out of the shower?

Sullyoon took in the scent, too, distracted from the enormous mistake she'd just made. The smoke snaked into her nostrils and filled her with the scent of.... Mmmm... the pine trees she'd smelled on the mountaintop in Colorado last year when the family had gone skiing, but there was also the scent of old leather, like that of the boxing gloves and bag she loved watching her brother use to work out.

"Okay, my dears, I've wrapped your purchases up as best I could. I hope you enjo......" As the old woman turned the corner and saw the two siblings standing over the broken flask, she knew exactly what had happened. She cursed herself for leaving the key in its usual spot. She should have known that the curious brunette wouldn't leave it alone.

"Out with you! OUT!" she cried. “You don't know what you've done. I TOLD YOU IT WASN'T FOR SALE."

Jae grabbed his sister's hand and pulled her past the old woman with a stammering apology. In a few seconds, he'd whisked his little sister through the store and out the front, her thick black hair trailing behind her as they went. They had to leave their potions behind. He doubted they'd have worked anyway. The old woman called after them as Jae and Sullyoon galloped down the street.

"FOOLS, CARELESS LITTLE FOOLS THE BOTH OF YOU!" she squawked, coughing after the effort.

She may have said something else, but neither of the two could distinguish it as they emerged from the alley. Jae thought he heard her say, " Get far away from each other," halfway through her sentence, but that couldn't have been it. Sullyoon bent at the waist to catch her breath, and Jae put a hand on her lower back. They both laughed and laughed; it had indeed turned out to be an interesting morning.

"I can't believe you just did that, Sullyoon," he shot at her, still giggling. “What if that old witch had put a hex on you?" he joked.

"Didn't I say we should go down that street!" she beamed proudly. "But we have to go back for our potions!"

"Come on, Sullyoon, you don't believe any of that nonsense, do you?"

Sullyoon bumped him with her hip and reluctantly sided with him as they headed back toward the center of town. But even as she agreed with her brother, his hand upon her waist felt slightly different; perhaps it was just the fact that she'd rolled up her shirt, and his strong palm was now completely upon her bare flesh.

No, that wasn't it. As she walked along, her head began to feel light, her body almost weightless. She stopped walking and put a hand to her head. Even before he spoke, she could sense him there, her big brother questioning, "Sullyoon, is everything okay?"

"Yeah, Oppa, I'm fine, just a little winded from our escape."

"Looks like someone needs to work out a little more," he mocked, then surprised her by spanking her butt daringly. She wasn't sure why she didn't lash out at him; she usually would have.

The place where he'd touched her on her butt cheek felt sensitive, ticklish almost as she started walking again. She nuzzled closer to her brother, not knowing that the potion was working despite her.

But whatever it was, it hadn't hit Jae yet, as he was bigger and more complex to dose. However, he couldn't help but enjoy the feeling of his arm wrapped around his little sister's taut abdomen. He had, at times, admired how strong she kept her core. He'd seen it so many times when she came home from the gym, always looking incredible in her sports bra and tiny workout shorts.

But after probably ten more steps, he began to feel it too, whether he knew it or not. His fingers depressed into Sullyoon's soft side on their own, stretching as if to gather more flesh. When she stopped to catch her breath and his hand slid from her, Jae suddenly wished he could put it back. He watched her as she leaned against the wall and looked away from him.

Sullyoon was feeling a bit frightened by it, by the sudden feelings she could only describe as horniness. But it wasn't for just anyone; it was for the attractive young man now touching her cheek to calm her down. He could tell by her breathing that she was wound up about something, but he could not have seen the kiss coming as he turned her face to his.

It was a hungry kiss, and Sullyoon stole a few seconds before Jae pulled away.

"Sullyoon! What do you think you're doing?" He asked, the potion still fighting to control him.

But Sullyoon didn't answer him. She looked at him lustfully, similar to how he'd seen her look when she was inspecting the potion that was now working its way through their bodies. And she stayed there against the wall, turning so both her shoulder blades made contact with the cool brick wall. She arched her lithe body so her hips met her brother's; he was standing entirely too close.

And then, as if on their own, Jae's hands found the exposed sides of Sullyoon's abdomen as it thrust toward him. He leaned into her, his front lining up with Sullyoon's as his hands got bolder. At first, they squeezed at her flexed abs, marveling at their remarkable firmness. But within seconds, they had jumped to her breasts, those fabulous globes he'd been denying himself looks at for years. When they landed there, his lips were magnetized to Sullyoon's, and they locked again in a feverish kiss, this time with both of them on board.

With their lips mashed and their tongues entwined, the two siblings felt each other in ways no sibling is supposed to, which was terrific. Sullyoon's tits, covered only by the tiny spaghetti strap shirt, felt glorious in her brother's hands. He massaged them and pinched at her nipples through the cotton. Sullyoon moaned into her brother's mouth.

"Oh God, Sullyoon," Jae said, pulling away from their kiss a few inches. What are we doing?"

Again, Sullyoon didn't speak; she just stared into his eyes as he kept his hands motionless atop her breasts. Sullyoon's gave Jae's cock, hardened since their first kiss, one more push with her hips and Jae flinched with a hopeless look on his face. Wordlessly, the pretty little brunette descended slowly to her knees, and though it was her first time, she gracefully opened her brother's pants and reached inside.

It was all happening too fast. Jae had not but a few seconds to interrupt his sister's actions, and when he felt her tiny hand wrap around his shaft, the decision was made for him. He could only watch... watch as Sullyoon worked his dick through his pants and out into the open. He could only watch as she admired it, pointing directly at her mouth and within seconds -- engulfed it.

Sullyoon choked a little bit as she took her brother's hard length into her mouth. It was warm and so thick that she had to open wide to fit it. After sucking gently at the first few inches of him, she took Jae's tip to her pursed lips and kissed it, following the peck with the lapping of her tongue. Her saliva coated him, and when she was satisfied with his shiny helmet, she looked up at him and locked his gaze. Slowly, she pressed his tip through her lips and into her mouth. She kept going though, and before long she had taken half of his cock into her mouth, eyes still holding his.

She pressed a bit further and felt him make contact with the back of her throat. Sullyoon gagged and withdrew, and once she had slipped him from her mouth again, she smiled proudly at how her brother was enjoying the treatment. So she continued it, sucking and bobbing her head toward the base of his cock. Jae looked around; his sister was blowing him in the middle of a side street, and he could hear people moving about in the town square nearby.

Somewhere a street performer strummed a guitar, but the sound was far overpowered by that of his sister slurping at his penis in her mouth. This continued briefly, but Jae wished it would never end. His worries of being discovered melted away with each following plunge of his little sister's mouth around his cock.

Sullyoon could have stayed like that until he released a big load into her mouth, feeling as if she'd enjoy the taste of him on her tongue. But it was not to be, for Jae pulled her to her feet and was kissing her once more before she even had time to catch her breath. The elixir finally coursed through him from head to toe, and Jae had but one mission. He took the bottom of Sullyoon's folded shirt in his fingers and pried it over her head.

Her breasts jiggled free, defying gravity as she held her arms over her head with her beautiful pink nipples standing at attention. He put a hand against one and another to the button at the waist of her tiny jean shorts. In less than a second, he had them unbuckled, and his free hand was pushing both shorts and panties down his sister's long, fit legs. They bunched at the bottom, and Jae could see that Sullyoon had been wearing yellow cotton panties to match her top, now bunched beneath them on the cobblestones.

It didn't take much for Sullyoon to push her brother's pants down the rest of the way, and then they both stood there in the street, brother and sister, naked as the day they were born and about to fuck.

Jae looked around, not out of the fear they'd be discovered but in search for somewhere to fuck his sister correctly. An abandoned food cart with an old piece of canvas thrown over it provided the perfect spot. So strong as he was, Jae lifted the naked little brunette, and she wrapped her legs around him. They kissed in their standing position, with Jae's cock pressed firmly against his sister's dripping pussy while they did. Slowly, he moved her over to the spot, not wanting to disrupt her eager playfulness as she nibbled on his lips and tongue.

Her soft cheeks touched the canvas, and Jae set her weight down upon the cart hastily, eager for what would come next.

They both paused.

Jae's rod pointed directly toward the place they both wanted it: inside Sullyoon's inviting little pussy, and soon. With one last ounce of resistance shown upon each sibling's face, Jae looked down to see what he was about to do, the incest he was about to commit with his little sister. He gazed up at Sullyoon; her beautiful body was sprawled out in front of him with her pink pussy waiting for him to push passed her puffy lips and take it. Two bystanders down the road walked by and saw them. One looked twice at what was going on down the street and quickly gossiped to a woman walking alongside. Jae felt a pang of guilt along with the heat of his sister's opening when his tip touched against it.

"Oppa... be gentle, I'm a virgin."

That did it. If there was any hope of stopping before, his sister's sweet words, both revealing her secret and inviting him to wash it away, had him entering her without another word.

His head split her tiny lips.

"Ohhh Oppa....unhhhhhhh," gasped Sullyoon.

He continued pushing into her ever so slowly, encountering resistance.

"Sullyoon, take my hand. This might hurt a little," her brother warned her. She wrapped her fingers around his, and Jae's other hand supported his little sister's back. He knew they may have onlookers, but taking his sister's virginity seemed much more important to him then. He urged forward, feeling her hymen give. Jae saw the teen wince in pain as the incestuous penetration took place. She squirmed underneath him, wiggling about his impaling cock.

Further he went; another person had slowed to see what was going on by the abandoned cart, though it is evident once Sullyoon let out an adorable squeal. Her brother had only just breached her hymen, and she felt complete. Sullyoon couldn't see the onlooker, but it wouldn't have made any difference to her; she was fixed on being manhandled by her big brother and had no plans to turn back. Jae might have done something differently if the potion hadn't tossed his inhibitions to the wind.

"Are you okay, Sullyoon? Do you want me to take it out?" Jae asked, his voice laden with compassion. Sullyoon settled down a bit.

"No!" she quickly replied, feeling him withdraw a fraction of an inch. He stopped immediately, "I only need a second....mmmmmmn..... owwwww... It's just huge, Oppa..."

Halfway buried in his sister's pussy, Jae was afforded a second to gather his thoughts. Something had changed between them, and he was almost sure the old woman had not been brewing sugar-water in her dank old store. But the earlier feelings of guilt weren't there anymore, and despite that he knew he shouldn't currently be immersed in his little sister's quim, it didn't change the fact that he loved the feeling and wanted more. He had only entered her by an inch, and she already felt unfathomably tight.

"Okay, Oppa, go slow," Sullyoon begged. Her brother smiled at the pet name she sometimes used and snapped back to the reality that was his sister asking him to start fucking her again.

They both looked down at Jae's shaft, half buried in Sullyoon's pussy and ready to go all the way. He began to push more of it into her, so slowly that Jae could feel his patience being tested. What he wanted to do was to feel Sullyoon's legs wrapped around him as he drove into her with satisfying and forceful thrusts, but it would have to wait. Sullyoon's face still showed that her body was adapting to Jae's size, and though he could see her enjoying it, he didn't want to ruin the moment. Instead, he leaned in and kissed her, distracting her as he sank the rest of his cock slowly into her.

The anxious eighteen-year-old felt her worries subside as her brother penetrated her, relieved that the pain of losing her cherry had not been too great.

Jae was planted there, kissing his little sister with their hips connected below. Sullyoon couldn't control her breathing from the unfamiliar feeling of being filled so profoundly; her entire abdomen had expanded along the length of his cock within. She was unfathomably wet, wetter than any girl Jae had been with before. His hand cupped her face as her eyes widened due to the intense feeling of her brother's entirely invading member.

"Mmmmnnnhhh," she moaned into his open lips.

His tongue teased her big, red lips; he could taste the strawberry chapstick she always wore on them. Jae savored the kiss as he slowly withdrew his cock and Sullyoon moaned again. Thankfully, her lithe little body had prepared her teenage tunnel for her brother's cock with her wetness, for it hurt her far less than she'd imagined. She was eager for her brother to sink into her again when he said:

"Are you sure you're okay, Sullyoon? I don't want to hurt you."

She nibbled at his lower lip and then pecked a few quick kisses on him with pursed lips; Jae loved how she played with him.

"I'm sure Oppa, you can fuck me now I think," she replied, pulling away from his face and wearing a naughty, come-hither grin.

Jae would never have admitted it until the potion came along, but his gorgeous sister frequently visited his dreams, sometimes in the very position she now lay. He couldn't have even dreamed, however, of taking Sullyoon's virginity, a thought which made the next thrust into her all the sweeter.

Suddenly filling her in one deliberate thrust, Sullyoon truly experienced the feeling of being fucked by her brother. As his shaft slid between the squeezing walls of her pussy, she could feel a tingle run all through her body and cause her mind to flood with light-headed bliss temporarily. When he bottomed out in her, and his head had reached further into her than she thought possible, her vision blurred.

"Ohhmygodd Oppa, keep going...mnhhh.... do it again," she encouraged him.

Withdrawing, he instinctively palmed the hipbones of his eighteen-year-old sister's tiny waist. As he'd wished, he could feel his sister's soft soles waiting for him to pull out before urging him back in. They watched, entranced, as the shaft revealed more and more until her clinging pink lips released her brother's tip. It looked glistening wet.

Sullyoon drew a breath to ready herself, and Jae dove back into her at a needier pace. Now that he had been inside his little sister Sullyoon once, no twice... he had to be snugly inserted again. He wanted to bury deep into her and hear her squeal with delight as he tickled her more than he ever had during the wrestling matches they still got into that day.

And when he did, she rewarded him with that and more:

"Ohhh, Ohhfuck --" she winced, "OhhhhmyGoddd!" He had reached somewhere that made his little sister writhe upon his deeply penetrated rod. "Keep fucking me like that Oppa," she spoke on as he hesitated, buried inside her. "I can't believe my brother is taking my cherry, and it feels... mnhh... this good."

Jae pulled out of the little brunette and sank into her again, and again, and again- it was precisely what Sullyoon wanted. Before long, he had worked them both into a tangle of pawing and touching and attempted to urge Jae deeper into her if possible.

The sun only struck the wall across the street about a quarter of the way down, and they may have been in shadow, but a small group had stopped walking momentarily to be sure they were seeing what they thought they saw. Sullyoon didn't hear them until a younger woman in the group giggled aloud, but as she saw them and then looked back at her brother, she pleaded in the cutest way she could muster:

"Don't stop," he thrust into her again, "please" she whispered as her brother's thudded against her mound and her tits shook, "don't you stop." Her puppy dog eyes shone brightly.

He didn't. Jae felt as Sullyoon did: that the forbidden nature of their lovemaking was only made more exciting because they were doing it on the street, where anyone could see them. For all they knew, their parents could walk past that street by chance and see Sullyoon and Jae locked in a loving embrace.

"What if our dad came walking around that corner... ooooouhhh....huh, Oppa?" He slid in and out as she goaded him, "what if he saw his little virgin, his naughty little girl.....uhhhhh.....fucking her big brother?"

Jae felt his cock swell with excitement, he'd never heard Sullyoon talk like this, he thought. Maybe he'd heard her say the word 'dick' on the phone with a girlfriend once or twice, but to listen to her talking dirty like that made him fear he might cum right there in her tight pussy.

"He might see me cum inside you then... ughh.... Sullyoon, you're so tight, baby. I don't know how long I can hold on."

"Ummmm...it's...ouhhh... It's okay, Oppa....I'm on birth control..." She sounded unconvincing and looked away from him as if to avoid eye contact. He wasn't positive, but he was pretty sure she was smiling.

"Sullyoon, you're lying, aren't you? " he asked. She put her finger to her lip and nibbled at it naughtily.

"No, I'm not.... Uhhhhh..... don't worry, you can put all your big brother cum in me Oppa...." She was looking at him through sultry, dazzling eyes.

"Sullyoon, I can't..." he couldn't help but slide his cock into her one more and continue, "you're only eighteen...and you want to be an idol...we aren't using protection."

The potion may have helped them get there, but it was Jae's innocent little sister who, now having felt her brother's big cock inside her, wanted nothing but to feel him fill her with his forbidden cum. She knew she was ripe to find herself knocked up by her brother, but the thought only excited her. In her mind's eye she saw her brother fucking her from behind as she stood standing against the wall, waiting until he shot up into her carelessly. So in reality, as her brother withdrew from her once more, she moved a foot to his pelvis to stop him from skewering her again and to let her get up.

Jae watched in awe as his little sister sat up, her abs flexing beautifully, and hopped down from the cart. She walked to the nearby wall and stood with her legs spread apart slightly so he knew exactly where to put his feet. Just like the image in her head, Jae immediately put his hands on her body, caressing her sides before taking her hanging breasts in his hands. They were incredibly soft, their weight hanging down into his greedy palms.

But nothing felt as good as that of his cock head making contact with Sullyoon's taut, young opening once more. Jae positioned his tip correctly and pushed into his beautiful, teenage sister, hearing her gasp. As he slid upward into her, the feeling satisfied her dreams more than she could have possibly imagined. It was somehow different, standing in front of her brother, completely naked and completely at his mercy.

He'd been worried just before that, and Sullyoon wanted to put him at ease:

"Your bad little sis wants you to fill her up with your sticky cu, Oppa," Sullyoon said pressing her cute butt back toward her brother to urge his cock into her and then out again as she provoked him, "Don't you wanna cum inside me big brother?.....mnnnnghhhhh."

Jae met her hips with his own, a quiet clapping of their flesh emitting from his hastened tempo. He couldn't see them, but the feeling of her glorious tits in his hands, the scent of her thick, dark hair from behind, and the smoothness of her skin had him mesmerized. He could only fuck her harder as he marveled in the beauty of her, in the freckles that kissed her shoulders and the bead of sweat rolling down the flexed arch in her back.

"Fuck me Oppa.... Fuck me just like that....ohhgod..."

What was the feeling that had suddenly rushed upon her? All at once, she felt short of breath and light headed. Jae could feel her relying on him to hold her up as he thrust into her. Her insides clamped down upon him, and he knew what was happening. Sullyoon was confused and yet deeply enjoying the feeling of her brother fucking her from behind.

"What is.....oohohooo Oppa... I can't breathe..... ughhh I feel like I'm gonna.... ooohhh."

Jae pushed her hair across her neck as he cleared a space to kiss her tender skin. He laid one on her, warm and loving, and another, moving closer to her ear. Sullyoon was trying to quiet her cries as her brother manhandled her and impaled her from behind with his enormous member.

As she felt his kisses and finally his teeth nibbling at her ear, her body exploded with sensation. It coursed through her veins and flushed from her all but the feeling of her brother's rod. Her pussy clamped down even harder, impossibly tight upon him, and try as he might he couldn't contain himself any longer. With only one more withdrawal from his squirming and panting sister, her taut channel had him releasing a first, deep jet of sperm as soon as he had pushed inside her.

"Ohhhhhwwwuuuu..." She howled adorably.

Jae hugged her body tight and tried to keep kissing her. He pumped rope after rope of cum into her fertile womb, so much that she could feel its plentiful warmth inside of her. Jae's whole body buzzed. He lost himself in a wonderful trance caused by the triumph of breeding his amazing little sister.

Sullyoon kept quivering long after the last powerful pump of sperm had left her brother's cock. He dared slide an inch or so out and into her, once so that she shivered and again so she whined at the utter sensitivity of her inner walls. He kept doing it, though it was excruciatingly pleasurable to them both, feeling their combined fluids trickling out around his penetrating staff.

"OhmygodSTOP! I can't take it!" Sullyoon screamed, looking back at him incredulously. She had not yet come all the way down from her heart-wrenching orgasm and couldn't handle any more. He still felt so enormous inside of her that she wondered if she'd ever recover. Yet she managed to survive even that of her brother's last heedless penetration into her before he finally came to rest.

She let loose the same smile she'd revealed after her fake-mad tantrum earlier that day, except this one meant a lot more.

"We're bad, Oppa," she said, feeling his cock starting to soften inside of her. "I can't believe you came in your own sister's pussy!" Suddenly, she sounded condemnatory.

"Sullyoon, I thought you said..." but she cut him off:

"Shhh, Oppa, I'll give you a pass if you do it again before we go back and find Mom and Dad."

His eyes shot to hers; she had finally slid him out of her (though she had to stand on her tiptoes to do it) and was turned to face him. Sullyoon reached down and took his shaft in her dainty hands; it stopped softening immediately. Jae looked down to see her glistening body, with her round breasts and the most perfect frame he'd ever laid eyes or hands on. He knew then that he'd never say no again.

Sullyoon kissed her brother so passionately and deeply, standing there in his arms, that he knew their tryst hadn't been all the elixir's doing. Her prying lips and fumbling hands told him how badly she'd wanted him. Jae returned the sentiment, satisfying his little sis with his hands over her bare skin. The few tender moments allowed both Jae and Sullyoon to recover, and before long, he could tell that his little eighteen-year-old wanted him again.

Jae picked her up by the hips and within moments was fucking her recklessly against the wall. The brick was rough on her naked back, but she'd cared only for the feeling of being fucked again by her brother. The cum from their lovemaking minutes earlier only eased the rhythmic immersion of Jae's cock into his beautiful little sister.

He humped her against the wall until he could hold her no longer, and then she sat him atop the crate and rode him until they both came again. She thought he might not have it in him, but as she felt another surprising amount of her brother's sperm pumping into her and increasing their risk, she knew she'd been wrong.

After God knows how long, the two siblings had somehow gathered themselves enough to try and find their parents. Jae had to smooth back some of Sullyoon's tussled hair, and once, Sullyoon had to check to be sure her dad wouldn't see a trail of her brother's gleaming spunk coming from the place he'd left it and showing outside her miniature jean shorts. When they finally met back up with their parents, they heard:

"Kids! We've been looking all over for you; we were starting to get worried," said their mom, hugging as they reunited.

"No reason to worry, we were doing great alone," Jae replied

"Oh yeah?" asked his mom. "What did you two get up to today?"

"Only naughty stuff," Sullyoon said, sounding sarcastic. The look she flashed him, undetected by their oblivious parents, said she knew exactly what she'd meant.

"Ha-ha," finished her brother. She meant that we might have gotten shooed away from a hat store for horse-playing, but we found plenty of things to fill our day.

Sullyoon's eyes lit a little, and she giggled: "Yeah, mom and dad, Oppa helped fill up my day. He's really good at it!"

"I'm glad to hear it, you two," said their dad. For a second there, Jae, I thought you were going to have your hands full with Sullyoon in the mood she was in."

They both chortled a bit, but their parents figured they were finally getting along; they didn't know how full their son's hands indeed had been.

"Yeah, I was in a great mood today for some reason," Sullyoon went on as her brother's gaze begged her not to say anything bolder. "Hopefully, Oppa can help me have a day like this every day this week!"

Jae's imagination ran wild for a few seconds as he thought of all the ways he wanted to explore the perfect little teenager's body. The potion had long since worn off by then. Its effects had genuinely gone by the second time they made love, but it left behind something far more significant. Having broken through the taboo of fucking their sibling, the potion had allowed Jae and Sullyoon to take what they'd been denied all along. Neither of the loving siblings could wait to be alone again so they could once again fuck each other senseless.

As Sullyoon strode along and walked next to her dad, bouncing and glancing over her shoulder occasionally at her brother, Jae was entranced. The entire return to the hotel, Jae planned out how he'd somehow maneuver her to a private place so he could wait the absolute minimum amount of time before being buried inside his little sister once more. Sullyoon was waiting anxiously for the same thing.

They were undoubtedly in for a hell of a week.
