Warning: my first rated M, so please review/criticize. I'd love to make my writing better so all critique is welcome. Oneshot between HaruhixHikaruxKarou - You have been warned. Also, I hope everyone has a Happy Holiday, hehe. :) I hope this gets you in the holiday spirit!

Under the Mistletoe

Hikaru quickly embraced Kaoru, wrapping his arms around Kaoru's waist. "You know the only gift I want for Christmas is you..."

Kaoru bashfully leaned his head against Hikaru's chest. "But I can't wrap myself up and give myself to you as a present!"

Hikaru tipped his twin's chin up and looked deep into Kaoru's eyes, "I always tie you up and make you mine on Christmas, why should this year be any different?"

The group of girls watching them squealed in enjoyment as Karou blushed against his twin.

Passing them, Haruhi rolled her eyes in disgust. She didn't understand the girls' fascination with the twin's "brotherly love". It was all absolutely repugnant to her, especially when she knew the twins' true feelings for each other were far more innocent then they made it seem.

She was beginning to truly understand the twins and recognize their actions and emotions. She could also tell the difference between them without even looking at them; even their voices were starting to sound different to her. She didn't know if it was because they were growing more independent of each other or if it was because she was getting to know them better with each passing day.

Suddenly, the "Powerful Motor" came to life as Renge ascended from the floor with an arrogant cackle. "Attention," she spoke through the microphone. "In two days' time, the Host Club will be hosting their annual Holiday Gala. If you have not already, please pre-order your spot on the guest list as soon as possible."

Haruhi gaped at the place where Renge continued to babble to the girls nearby. "H–Holiday G–Gala?!" She spun around to meet Tamaki and the twins as they smirked at her expression.

"Why didn't anybody mention this to me?!" She shrieked, causing a few of the girls to look over at them. She lowered her voice, "I don't have to go, right?"

"Of course you have to go," Kyoya interrupted. "You still have your debt to pay off, so this gala is mandatory. For you, at least."

Haruhi just stared as Kyoya gave a small smile and stalked off. She then turned to Tamaki, "So, ah, what's the dress code for this dance?"

Tamaki gave an intimidating grin and pulled her across the Host Club area and into the dressing room.

Haruhi tugged at the uncomfortable suit she was forced into. It was sort of creepy that Kyoya knew her size and already got a suit tailored for her.

She was reluctant to come at first, but after she arrived, she was stunned by the work the Host Club put into creating the perfect gala. Glowing Christmas lights lined the walls and ceiling, intertwined with boughs of holly and mistletoe. The red of the berries collided with the green of the leaves in perfect harmony. Circular tables lined the perimeter of the ballroom, leaving the center strictly for dancing. Couples twirled and glided in unison, resembling ballerinas. The entire room shimmered, in contrast to the dark snowy night outside.

It was beautiful.

She had no idea how the Host Club produced such a bewitching atmosphere in just the time they had after school. She spotted Tamaki across the expanse of dancers and guests picking at the extensive buffet. A young woman collided into her before she could reach him, however. Haruhi gave out a quick apology before trying to hurry on, but the girl stopped Haruhi in her tracks. She was quite small, with pixie-cut black hair and a flowing blue dress that hugged her figure perfectly. Haruhi recognized her from Host Club, though the girl usually requested Tamaki or Honey.

"Haruhi!" She pulled her hair back from her face flirtatiously. "I was wondering… Are you going to dance tonight?"

"Uh," Haruhi stuttered incomprehensibly. "I'm not very good at dancing, so I'm not exactly sure..."

She heard a gasp from behind her. She turned to see Tamaki gaping alongside Kyoya in horror. The girl walked away in disappointment, passing Tamaki and Kyoya on the way.

"Haruhi!" Tamaki exclaimed. "That girl was asking you to dance!"

"Uh, no. She asked if I was going to dance tonight. And what're doing eavesdropping?"

Tamaki dropped his head in defeat, while Kyoya just watched the two of them in amusement. "What am I going to do with you, Haruhi?" Tamaki finally replied.

"Well, I was trying to find you anyway." Haruhi continued, ignoring his previous comment. "The place actually looks spectacular! You guys did a really great job!" She said with untypical enthusiasm.

Tamaki blushed. "You think so?"

"Mmhmm." She replied then looked around for the rest of the Host Club. She could spot Honey and Mori, eating by the dessert table, but was unable to find the twins. "Do you know where Hikaru and Kaoru are?"

Tamaki turned to the dance floor, scanning the area like an overprotective mother. He cocked his head and pointed to the edge of the floor. There was a crowd of girls, blocking Haruhi's view. She sighed and walked over to the horde. She pushed herself between the girls as they squealed and giggled. Once she caught sight of the twins in the center of the throng, she understood.

She blushed heavily as she watched the twins dance extremely suggestively. They might as well be fucking each other on the dance floor. Her heart thundered in her ears as she stared at them. Hikaru had placed his hands on Kaoru's lower back, slightly dipping his fingers into his brother's waistband, stroking the skin there. Kaoru had his arms around Hikaru's neck, his fingertips playing his feather-light hair. One of Kaoru's legs was propped onto Hikaru's hip as the older brother dipped him dramatically, their groins rubbing against each other. Both of their gazes were locked with each others.

How it was legal that they were allowed to do this in public, Haruhi did not know. She also didn't understand how they could keep up such a convincing act in front of the other girls, though Haruhi herself refused to be convinced. The twins loved each other, but she was sure that their love stopped at brotherly. Finally, she called the twins names, still blushing furiously at the show they were putting on.

They ignored her.

Confusion swept over her. Did they just not hear her or were they mad at her for some reason? "Hikaru! Kaoru!" She repeated.

Nothing.

They were blankly ignoring her. The other girls surrounding them looked at them uncomfortably. Haruhi glared at the twins then walked away.

So the night continued. Haruhi took turns dancing with the girls who requested her, under Tamaki's duress, and proceeded to satisfy the guests throughout the night. After a while, she was starting to enjoy herself a little; though since the twins were not saying a word to her, her enjoyment weakened until she was absolutely irritated with their silence.

Once the gala was over, Haruhi volunteered to clean up since the twins disappeared and the rest of the Host Club looked exhausted. Kyoya assured her that the school janitors would take care of it, but Haruhi insisted. She strangely didn't want the night to end. She wanted to stay under the mistletoe and lights as long as possible, and wanted to keep the lingering holiday sensation.

As she swept the floors, she suddenly heard a crash then whispering down the hall. She immediately realized the stupidity of being alone after midnight in an empty school. She sighed, leaned the broom against a nearby table, and set off to discover the source of the noises.

She slipped into the hallway, following the sound until she reached a dark, empty classroom. She silently opened the door, and gaped at what was displayed.

Kaoru was splayed out onto a desk, his hands imprisoned within his brother's. Hikaru, with his shirt and jacket mysteriously missing, straddled him, with his fingertips caressing Kaoru's chest. Their lips were locked in a furious embrace, moans spilling from between their lips in ecstasy.

Haruhi ogled at the pair of brothers, frozen in complete shock. Her entire belief system came crumbling down as she watched the twins passionately stroke each others' tongues in utter pleasure.

She knew the twins like the back of her hand.

She knew how Kaoru was gentle and forgiving.

She knew how Hikaru got upset easily.

She knew how Kaoru had a small scar on his right wrist.

She knew how Hikaru always bit his lip when he was offended.

If she knew all these trivial things…. Then, how could she not have realized the most important thing about them? And, additionally, why couldn't she stop gazing at them?

She could not stop staring.

Hikaru moved onto Kaoru's neck, sucking and biting the skin there. They had no idea she was there, or maybe they wanted her to think that they were oblivious. She started to breathe heavily as she watched them groan. Kaoru wiggled beneath Hikaru's hands as they moved down his chest onto his hips.

She could not stop staring.

Something pulled her into the classroom. As she stepped through the entryway, though, the door shut behind her with a bang. The twins stared at her in mock surprise.

"Haruhi!" Both of the twins gasped.

"Oh, no! You've caught us..." Kaoru sighed.

Haruhi blinked at their obvious lying. What was going on here?!

"I–I…" She gulped. "Wh–What're the two of you planning? This must be some sort of ruse to… do something..." Her voice trailed off. They continued kissing as she spoke, causing her to lose focus on the conversation.

Kaoru interrupted Hikaru's kiss. "Oh, were you speaking, Haruhi? We were… distracted. And to clear things up, we were messing with you the entire night."

Hikaru continued his twins' thought. "We could tell that you don't enjoy our performances during Host Club, and at first we were upset with you for dismissing us."

"But then," Kaoru went on. "we decided to show you how our performances aren't so far off from how we really are." He paused to look deeply into Haruhi's eyes. "Would you like to play with us?"

Haruhi was far passed the ability to speak, and as the twins continued to touch and kiss each other in places she had yet to discover, her eyes glazed over. She couldn't do it anymore. She couldn't pretend that the two of them didn't turn her on when she felt her insides quake and felt herself become wet with desire. Haruhi may not have been knowledgable in things like this, but she knew what her reaction meant: she was incredibly aroused by them.

Looking back, Haruhi didn't know what brought her to walk towards the desk they laid upon. Maybe it was curiosity, or maybe it was true affection for the twins she supposedly knew so well. Either way, she chose to play.

Shirtless Hikaru turned to her as she walked towards them, taking her approach as consent. He jumped up from the desk where his brother lay and knocked her knees out from under her, cradling her to his chest. He placed her on the floor and pushed her small body underneath him, causing her to splay out beneath him. Her breath caught as she noticed him watching her with his intense gaze; his passion was something she never saw before in the twins.

Hikaru began kissing her neck, gently biting and licking her smooth throat. Haruhi gasped at the unfamiliar sensation, then relaxed and reveled in the feeling of his soft lips against her skin. She jumped in surprise when Kaoru started touching her… down there. She clenched her body as Kaoru stroked between her legs, rubbing her mound beneath her thin pants. Unsatisfied with her clothing in the way, Kaoru stripped her pants, socks, and shoes off with a flourish, revealing her panties to the younger twin.

Hikaru, impatient with Haruhi's attention on Kaoru, passionately fused her lips with his own. As he caressed her velvet lips, she couldn't hold back the moan that resonated throughout her form. It just felt so… right, him kissing her. She could feel his excitement with his hardened member gliding across her bare thighs. Encouraged by her moaning, Hikaru slipped his tongue between her lips, stroking her own tongue with care.

Kaoru moved onto her chest, unbuttoning the expensive jacket and removing both her shirt and tie. He pulled down her bra slowly, admiring her breasts as they grew perky in the cool air.

"K-Kaoru!" She protested, breaking away from Hikaru's kiss. She attempted to cover herself, realizing this went too far, but Hikaru grasped her hands and pulled them onto either side of her head. He cut off her protest with another heated kiss and bit her lower lip gently. Kaoru continued to fondle his little girl's small, yet soft, breasts. Her petite body turned him on in ways her never fathomed before meeting her. Her small, yet sturdy, hips; her skinny, yet silky, legs; her undersized, yet alluring, chest. He tenderly rolled her nipples with his tongue and teeth, motivated by her sigh in response.

Hikaru, not to be outdone by his brother, broke away from the kiss to shove two fingers into her mouth. Her eyes bulged as he encouraged her to suck. Reluctantly, she wound her tongue around his fingers, not understanding the point but trusting him nonetheless. He grinned sinfully as he removed his fingers and tugged her panties farther down her legs.

"Hikaru, what're you- OH!" She cried as he plunged his fingers into her slit. With no rhythm, he thrusted his fingers in and out, in and out, of her tight and aching center. Her breathy moans escalated in correspondence to his tempo. "Ugnh, Hikaru! Don't… stop."

He chuckled at her untypical expression as he continued thrusting, thrusting, thrusting. His thumb started to stroke her mound slowly, causing her to shriek in ecstasy and force her hips against his hand. Her entire frame shook and she arched her back to get closer to those tantalizing fingers.

Kaoru moved down to her stomach, gently kissing her skin. He proceeded down to her hips and sucked the sensitive skin there. The combination of both Kaoru and Hikaru's actions were making her head spin in unfamiliar sensations.

Hikaru abruptly jerked his fingers out. Haruhi gasped in sudden disappointment and brought her head up to see what was going on. But before she could do so, Hikaru gripped the back of her head and brought her lips to his, once again. She wasn't complaining, only reveling in the sweet taste of Hikaru's tongue fondling her own. She had no time to realize that Kaoru soon replaced Hikaru's fingers until she felt the warmth of his tongue down there. She lurched up in embarrassment, trying to get Kaoru away from her sensitive area, but Hikaru held her down with another kiss.

She was blushing from head to toe as Kaoru led his wet tongue around her clit. Her heart pounded furiously. Tension escalated throughout her body as Kaoru lapped up her wet center. Haruhi gasped to the rhythm of his tongue. She could feel herself on the brink of something–

–When both of the twins jolted away from her.

"Hmm, I don't know if we're doing a good job. She should've come by now." Kaoru said.

"Well, maybe she just needs more visual foreplay before she's ready." Hikaru continued.

"I–I, ah." Haruhi gasped, wanting to tell them how close she was when they stopped. Then she realized that might've been the point. "Bastards," she said under her breath. They were torturing her.

"What should we to help her, Hikaru?"

"I don't know…" Hikaru said as he glided his fingers across his brother's chest.

Kaoru gripped his brother's fingers and tugged, causing Hikaru to topple onto his chest. Kaoru then wrapped his arms around Hikaru's neck and joined their lips with a sigh. Haruhi couldn't help watching when Hikaru removed his twin's pants, without breaking their kiss, and took out Kaoru's hardened member. He began stroking the skin and gently clenched his fist around his brother. Hikaru then broke away from their kiss to engulf the member within his mouth, plunging his head back and forth, and slowly licked the tip. Kaoru's head fell back in pleasure and he grasped Hikaru's hair as he groaned to Hikaru's ministrations.

Haruhi couldn't take it anymore. Her heated center begged to be given attention. So, a little reluctantly, she began to move her fingers down to her frustrated area and stroked her mound. Instantly, her senses were on fire. She closed to her eyes and thought of nothing else but the pleasure, moving her fingers in concordance with how it felt here and there. She might've been inexperienced in this subject, but she was a fast learner.

She didn't realize the twins' silence until Hikaru grabbed her wrist away from herself. Her eyes fluttered open to stare at the older twin, his gaze locked onto hers. He gulped, almost looking nervous. He separated her legs, gently clutching onto her thin thighs, and placed one on either side of him…

… And thrust himself into her wet center.

The pain came first, eliciting a small cry from her. But as he continued to plunge himself into her, the pain abated and in it's place came pleasure, more and more pleasure. He held her thighs as he thrust in and out, and in and out, and in and out. Her cries mixed with his groans. Her toes curled and her hands fisted and all she could do was grasp Hikaru shoulders as he moved. She swirled her hips around and tried to get closer to his manhood. Closer, closer, closer. Until she felt on the brink of collapse…

Hikaru growled out, "Kaoru, I can't wait any longer."

And then he spilled himself into her, finishing with a loud groan. Her eyes went wide as she realized she was so close, once again. She let go of Hikaru in defeat, yet still somewhat satisfied. She was about to get up when Kaoru replaced Hikaru… and entered himself into her.

"We're not finished yet." He softly whispered into her ear.

The tension picked up where it left off and she cried out as Kaoru pushed himself within her. His movements were much different from Hikaru's. Where Hikaru moved quickly and passionately, Kaoru glided slowly and sensually, hitting all the right places. Her mind quickly went blank with the twin's motions. Her breath fell short and her body clenched around him. She was at the edge again, even closer than before–

–And she let herself go with a powerful cry. Kaoru soon followed with his own groan and collapsed onto her small body.

Her mind was foggy, but she knew this changed everything. As she glanced at a breathless Hikaru and collapsed Kaoru, she knew this wasn't just another temptation strategy.

But if they weren't doing this just to spite and torture her, then what would be the reason behind it?

Edit: So... you guys are awesome! Thanks for the feedback!

Please comment if you liked it and want more! I think I will continue it throughout the summer, but I'm not sure if it should stand alone or not...
