Rating: MA / NC-17

Pairing: Blair/Chuck

Notes: This can be read in conjunction with 'Hurricanes' but also as a standalone. I ignored Blair's comment to Serena in 1.09 about sleeping with Chuck twice, because that's no fun ;). This is pretty fluffy, because they're always so fluffy when they're not fighting.

Summary: One month of Blair and Chuck, before it all fell apart. Set between Seventeen Candles and Hi, Society.

---

She was late and it was getting close to midnight. Chuck's patience was wearing thin, his hair a little more dishevelled, top buttons undone in frustration. He checked his cell for the 27th time, rereading her last message.

Drink with S, 15 mins. x

That was over an hour ago.

He could have easily picked up a Victoria's Secret model early in the night, relieved some tension, sent her home and be lounging at Pony with a strong nightcap by now. As it stood, he was still unsatisfied and painfully bored, and Leno was pissing him off.

His phone chimed and he flipped it open, finding an update from Gossip Girl instead of a text from Blair. His mouth closed into a hard line and he pressed 'read'.

A photo of Blair appeared, looking amused and flirtatious as she smiled up at some college yuppie whose father was on the board of a minerals giant, her hand on his lapel. He didn't bother to read the inane blurb, snapping his phone shut.

That minx.

He was considering his next move as he tamped down his rising anger, when there was a slow knock on his door.

Blair. Chuck considered not answering it. Serve her right after that manoeuvre.

But then, he'd still be unsatisfied, bored, and she'd probably be royally pissed off for the next few days. She hated being denied, he learned that very quickly. While he did like to see her squirm, he also just wanted to undress her and take her to bed.

"Chuck, I know you're in there," she called playfully. Intoxicated.

His jaw clenched as he made his way leisurely to the door, opening it to find her leaning against the door jamb, a hand on the curve of her hip. He eyed her tiny black dress, barely covering her ass, her hair loose for once, reminding him of the night she'd given her virginity to him. His heart gave a slow, strong thump.

"Hi, darling," she smiled prettily, a gleam in her eye.

"You're late," Chuck replied, unmoved.

Blair grasped the front of his shirt, pulling him towards her. "And you're all hot and angry. Someone didn't get their afternoon nap," she teased. She started to press kisses against his neck, pulling his shirt out of his pants.

Chuck tried to stay angry, he really did. But she smelled so damned good, like champagne and strawberries, and she was rubbing up against him like a cat in heat. He pressed his nose into her hair, unzipping the back of her dress while she made quick work of his shirt, running her hands over his chest.

When the backs of his knees hit the edge of the bed her hand was already inside his pants, stroking him to hardness, the other trying to rid him of the rest of his clothes. She was standing in her panties, small and pale and beautiful.

"I missed you tonight," she murmured against his mouth between kisses, breathless, his clothes now gone. He knew she wasn't lying and her words sparked something inside of him as her hands clutched him, touched him desperately. He kissed her harder, forgetting that he had to wait so long, because they both knew waiting for Blair was always worth his while in the end.

Blair knew he'd seen the photo of her the moment she saw his face, but she hadn't been able to refrain from being at the right place at the right time after the play he'd pulled in the courtyard the day before. So technically they were even and his lips were making a hot trail over her breasts and all thoughts of payback were suddenly forgotten. She pushed him back on the bed none too gently, climbing on top of him.

Chuck loved it when she took the lead but tonight he was impatient and the soft, eager sounds she was making were almost too much for his self-control. He flipped her onto her back and looked down at her flushed cheeks, her shiny pink lips. His insides churned as he gazed at her. He'd never wanted anyone as much as he wanted this girl.

"You'll be the end of me," he shook his head as he sat back on his heels, running his fingers over her soft, wet folds, thinking, She's all mine.

Blair smiled up at him, lifting her knees closer to her chest as he guided himself into her. They both moaned at the familiar pleasure, savouring the moment he filled her completely.

"Better be." She pulled him down for a kiss.

"I've hardly spoken to you since Thanksgiving, B," Serena said as they walked to Chemistry, girls moving aside to let them pass. "What have you been up to?"

Blair considered the question. Having sex with Chuck. Having sex with Chuck in his limo. Having sex with Chuck all over his hotel room. Having sex with Chuck on top of--

"Oh, you know, I've had a lot of homework. Plus my mom has a private show next week so I've been helping to ensure that it is fabulous, as usual," she smiled convincingly.

"Yeah, you seem pretty busy. Have you seen Chuck lately?" Serena asked lightly, attempting casual.

Blair's smile dropped, not wanting to rehash their Thanksgiving fight. "We… hang out sometimes."

Serena scrunched up her nose, concern on her face. "Are you sure that's a good idea?"

"We just hang out, okay? Drop it," Blair sighed, not wanting to think about it, let alone have a discussion with the reformed version of Serena about it. "It's nothing. And don't you dare mention it to anyone--"

"I know," Serena said, frowning, hating the feeling that something was wrong, or about to go wrong for her best friend. And this wasn't Blair. The sane Blair didn't have casual sex. The sane Blair didn't sleep with womanising assholes. "I just… worry. Because he's Chuck, remember? Not exactly Prince Charming."

"Well, I'm not Cinderella." Blair's phone chimed. She read the message and closed it quickly.

"That was him, wasn't it," Serena said, looking exasperated.

Blair couldn't hide her smirk.

Lunch. Drama theatre. C

The look of horror on Serena's face amused her. The blonde threw up her hands. "Okay, okay, I'm done doing the concerned best friend thing, I really don't want to know anyway." She threaded her arm through Blair's as they walked down the hall. "So backstage duty at your mom's show?"

---

Blair gasped, tightening her grip on the back of his neck, capturing his lips in a searing kiss. Chuck slowed his thrusts, trying to rein in his control or it would be over in moments, hitching her legs higher around his waist.

"I want to watch you come," he said, out of breath, so hard for her he was aching, and she moaned in time with his thrusts, wholeheartedly agreeing with his sentiments, grabbing onto the bar in his suite with both hands for leverage.

"I'm so close," she panted, wincing as the edge of the bar dug into her back. Chuck stared at her splayed before him, a slight sheen of sweat on her chest, and tried to memorise every single detail of the amazing girl in front him. Blair was perfect for him - her body, her mind, equalling him on the Upper East Side and between the sheets, her fire burning him and leaving him wanting even more.

Chuck's cell began to buzz and ring on the counter, startling them, and Blair laughed breathlessly, until she glanced over and saw that Nate's name was lit up on the screen. Chuck looked at her, then began to thrust harder again, and she felt her walls tighten around his thick length, the pleasure becoming almost painful. She squeezed her eyes shut, putting Nate out of her mind, because Chuck was right here, in the present, giving her exactly what she wanted. The only time she ever felt this electricity under her skin was here, just being near him.

The ringing finally stopped, then started anew a few seconds later, breaking his concentration. He swore, just wanting to come inside her, to fuck his best friend's girlfriend until she was screaming his name because she wanted him, and goddamnit, he'd told Nate to come over that afternoon before she'd turned up and had him stripped naked and inside her within minutes.

"He's already on his way," Chuck said, giving up, panting and still hard inside her.

Blair looked at him incredulously. "Don't you dare answer that phone."

He looked down at her angry expression, wanting more than anything to turn it into orgasmic capitulation. It was most definitely his favourite look on Blair's face. He picked up his phone before she could snatch it away from him and flipped it open.

"Hey man," he greeted, looking at her with a trace of a smirk. She looked like she wanted to kill him, daggers in her eyes, trying to push him away so she could get down but he held her firmly.

"I should be there in about ten," Nate said, sounding lacklustre. "I could really get blazed tonight."

Blair was still struggling against him as he walked to his bed and sat her on the edge, propping himself up over her with an arm. She was squirming around his cock, making it difficult to focus on Nate's words.

"Uh, now's actually not a good time, Nathaniel," Chuck said, making his meaning clear. "I'll have to reschedule."

Nate rolled his eyes. "Come on, man. Blowing me off for a girl? What's the deal?"

Chuck couldn't resist thrusting into her, watching Blair's eyes go dark and glassy as she attempted to get him off her, but then her breathing turned hard and she dug her nails sharply into his arms. He rubbed her clit in retaliation and she bit back a whimper.

"Nothing," Chuck replied, closing his eyes for a moment, willing his control to stay in check. He grinned. "She's just been… really riding me lately."

Nate could hear heavy breathing in the background, clearly female, and grimaced. "This is twisted, even for you. I'll talk to you later," he said, ending the call without waiting for a response. With Chuck always occupied lately, Blair not speaking to him, Serena being… complicated, he was getting sick of not having anyone to turn to.

"You are totally disgusting," Blair exclaimed furiously as soon as Chuck tossed the phone aside, putting his arms around her back to shift them higher on the bed without slipping out of her. "I cannot believe you just did that to me!"

"Relax, sweetheart," he said, pushing her legs further apart as he moved inside her leisurely, sitting back on his knees. "Would you rather he turned up at the door? I promised I'd make you come. Now we have the whole afternoon." He leaned down to kiss her, feeling her anger begin to chip away slightly, and her slender arms curled involuntarily around his neck as he pushed inside her harder.

"That was really fucking stupid," she berated, lifting her hips to meet his.

"You want to go home? We both know you need this," he said, punctuating his words with long, deep thrusts.

"I don't need you," she said, except it came out breathless and needy and she cursed herself silently.

"Not what you said earlier," he reminded her. She couldn't deny it, because she had needed him, had told him so, before leaping on him through the open door. Which had led to her being pounded against the bar because Chuck absolutely loved that she needed him.

Blair squeezed her eyes shut. Why couldn't things ever just be simple?

"Enough talking," she said, lifting her knees, earning a sly grin.

His lips closed around her nipple and she grasped his hair, staring blindly at the white ceiling, feeling his cock slide inside her with deliberate strokes. She wanted to block out the world and be allowed to just stay like this. She yanked on his hair so she could kiss him, wrapping her legs around his waist and remembering she could be loud because they were at his place.

Chuck smiled as she moaned, feeling the restraint leave her body as she arched and all the muscles in her form became fluid and yielding. He loved when Blair let go, when she was herself around him, opening up for him only. When she took exactly what she wanted with ease, without effort, since everything else in her life always came with a struggle.

He moved deeper inside her, feeling completely surrounded by her, relishing it. "What do you want?" he breathed, pushing her hair back from her face, wanting to give her everything.

Blair's eyes were unfocused as she gazed at him, soft hands sliding over his skin as her hips met his in perfect time. She gripped his thigh, guiding his rhythm. "I want…" She gasped as he hit her g-spot, inner muscles clenching around him.

He kissed her, pulling her bottom lip between his teeth, feeling the pressure in his cock start to build. "Tell me."

What did she want? Her whole life she thought she had always known what she wanted, but when she was here, it all began to get mixed up, and sometimes she didn't care that he saw her without make-up, her headband stuffed in her purse, or that she missed a party because Chuck wanted her to try the pecorino cheese with black truffle and dark chocolate crumb mousse from room service in the nude.

She felt the pleasure begin to coil like a spring, tighter and tighter, each stroke setting every nerve on fire. Blair pulled herself up onto his lap so they were sitting up and wrapped herself around him tightly, wanting them to come at the same time, and he kissed her as they thrust against each other fiercely, his face tense as he tried to hold back his orgasm.

"I want you," she said impulsively, and felt a sudden rush as pleasure flooded her body, white lights bursting behind her closed eyes, his moans echoing hers and filling her ears.

Blair's room was awash with warm afternoon sunlight, music coming from her laptop as she bit the end of her highlighter.

"You know I can make a call and that history essay will be done within twenty-four hours," Chuck said, as if it were obvious.

She gave him an uncompromising look. "I am not going to let you jeopardise my chances of getting into Yale with an easy fix."

He leered. "But an easy fix means… more time to fix you."

"I realise your ambitions only go as far as the length of your…" Blair glanced down at his crotch. "But this is actually important to me, Chuck."

"Then you'd know my ambitions are quite considerable," he said wryly. "And you also know I could get you on the shortlist."

"I'm not going to be indebted to Chuck Bass of all people, and besides, George Sand is my ticket in, it's practically written in the stars," she said smugly as she highlighted her textbook in fluoro pink.

Chuck looked up from her computer. He had been lazily stroking her calf, stockings long removed, trying to figure out where he wanted to go for New Year's. He was feeling partial to Barcelona this year. And Blair would love Spain.

"How do you figure?"

She smiled like a cat that caught the canary. "She's the Dean's favourite author. When he asks me who I'd have dinner with, he'll be wanting to dine with me when I give him George. And once I'm at Yale, life will be truly perfect," she sighed, wishing high school was over already so she could start her new, perfect life. Finally free.

They were sprawled on her bed after school, as they were whenever they both had a free afternoon, which was less often than Chuck liked. Between hiding from Nate, Serena and the rest of the world, Blair's anal retentive attention to her schoolwork and their social and family commitments, there was never much time left to spend… catching up.

"I'm sure you'll quickly bring all the hot sorority girls in line," he smiled to himself.

Blair suddenly tossed her history book onto the floor and snapped shut the lid of her laptop.

"Hey," he protested, moving to open it again but she pulled it out of reach. Chuck raised an eyebrow.

"All this talk is making me hungry," she said, crawling towards him with mischief in her eyes.

His mouth curved upwards, feeling his heart rate rise in anticipation. "Shall I ask Dorota to bring something up for the lady?"

Blair slowly unbuckled his belt, pulling down the zipper, and he felt his cock twitch. As she settled herself between his legs, Chuck couldn't take his eyes off her, watching for her next move. Her hand was warm and soft around him and he was hard in seconds, skin tingling from her touch. Her red lips hovered above the tip, doe eyes looking up at him. He had to remember to take a breath.

"Oh, I think I can bring something up myself," she smirked, and Chuck had already forgotten what they were talking about because she was kissing the sensitive tip before giving it a slow, thorough lick. He closed his eyes for a moment, muscles tensed, feeling as if time had momentarily frozen as that small, warm tongue circled his cock.

Blair smiled, loving it whenever Chuck gave himself over to her. It usually didn't take much either, all she had to do was arch her neck, touch him the right way, and he was good to go. He enjoyed kissing her, drawing out their foreplay until she was practically begging him, so she decided to tease him a little.

She ran her tongue over the thick length slowly, stroking unhurriedly with her hand, watching as the building tension and pleasure caused his eyes to become unfocused and heavy-lidded, and she felt her own arousal grow. She squeezed her thighs together, continuing her ministrations, only taking the head into her mouth briefly before licking again.

"God, Blair," he gasped. "Just do it already."

She stopped her movements with another smile. "Do what?" she asked innocently.

Chuck glared at her. "You know what."

She began to stroke him in earnest and he gripped the sheets. "This?"

His eyes gleamed, and he spoke through clenched teeth. "Close. But I want to be in that hot little mouth."

She acquiesced, lowering her mouth onto him so that his cock touched the back of her throat, her eyes on his. She slid him in and out of her mouth smoothly, tongue swirling around the underside, throat opening, lips sealed tight. He groaned, jaw clenching again. If he'd known Blair Waldorf was the best cocksucker this side of Manhattan he would've chased her a long time ago. There was something about being Blair's first that got his blood boiling, his body always completely in tune with hers, it was like nothing he'd ever felt before.

She brought him to the edge before bringing him down again, drawing out the pleasure and torturing him. He was panting, hand involuntarily squeezing her arm whenever he was close to exploding, causing that incredible mouth to slow down.

When Blair eased off for the third time, he rolled eyes in frustration and glared at her. "You're such a fucking tease."

She laughed, hand replacing her mouth on him. He was very, very hard and she relished the thickness, feeling him strain against her palm. "Whatcha gonna do about it?" she challenged, her voice like silk.

With a squeak of surprise Blair was thrown onto her back before she realised he'd even moved, with a determined Chuck above her. He kissed her almost violently, demandingly, and she heard her delicate, cream La Perlas tear as he yanked her skirt up and then his hot mouth was on her clit, tongue plunging into her entrance.

"Oh…god!" Her hands grabbed for the pillows above her head, clamping tight.

Chuck smiled when he saw how aroused she was from playing with him. To the outside world she was decorous and chaste, but inside, hidden away, Blair was just like him.

She loved when he went down on her, and this time he wasn't holding back, two fingers curling up inside her to rub that sweet spot that had her crying out loudly, while he sucked on her clit like it was candy.

Blair was breathing harshly, moaning and gasping, the pillow crushed between her fingers, toes curling as her orgasm approached.

"Fuck, fuck, fuck," she breathed, back arching, his fingers playing her like a violin. She was so close, so close…

Chuck stopped abruptly, licking the corner of his mouth with a wicked grin.

"That's a dirty mouth, Miss Waldorf."

"Chuck!" she wailed in protest, sitting up on her elbows to look down at him angrily. His voice was low and teasing and was turning her on even more.

His eyes became dark, zeroing in on her flushed form, her hair and clothing in disarray, chest heaving.

"Want you," he said before he pushed her back down with a breath-stealing kiss, driving his hard length inside her so that she gasped loudly and wrapped her arms around his neck. She was so wet he had slid in easily, all the way to the hilt. They looked at each other in relief, because nothing had ever felt so… right.

He slowly pulled all the way out of her hot centre, and her whimper turned into a delicious moan when she felt the head of his cock nudge her apart again, her walls clenching around him tightly.

"Oh, that's good," she sighed, wrapping her legs around his waist.

"It's gonna get better, kitten," he smirked, repeating the measured stroke just to hear Blair's little sounds. She moaned her appreciation, unable to stop running her hands over him. He put his mouth to her ear, biting the lobe gently and began to thrust steadily. "Can't wait to come inside you."

"Yes…" she sighed, eyelids fluttering closed, "Yes, yes…"

He'd made love to her before, several times, but this wasn't one of those times, it was raw and wet and hard, making her skin thrum with pleasure. She opened her eyes, panting, sitting up on her elbows to watch his cock slide in and out of her and revelling in it at the same time. Chuck was biting his lip and gazing down at her face with concentration, and then her orgasm hit her without warning, in strong, unrelenting waves.

"OH… FUCK!"

It took Blair a long moment to realise that she had cried out, clamping hard around him, and Chuck was laughing, then moaning her name, and she decided it was the best sound she had ever heard, she was utterly addicted to that sound. And suddenly he was coming, his entire body tense as she felt his cock throb inside her rhythmically, the world splintering, erupting until all that existed was them, the completeness of the moment.

A minute later he collapsed half on top of her, half beside her, turning her head to his for a kiss, fingers messing up her hair again. Blair circled her arms around his neck, slipping a warm tongue in his mouth. Sometimes she thought that maybe this was her favourite part, after the frenzy and the fighting, when she was just Blair again, and he was just her friend Chuck.

"Didn't even get my clothes off," she told him, realising she was still mostly dressed.

Chuck's breathing finally recovered, putting his arms around her to roll onto his back, bringing her on top of him. He undid the black Constance tie around her neck, as if to say, How's that?

She kissed his chin, eyes sparkling. "So. Another round?"

---

Blair's eyes met his across the darkened room at Jade and she swallowed, attempting to look unperturbed as she took a quick gulp of her drink, trying to stop her heart from beating its way out of her chest.

She assumed he saw other girls sometimes. Of course he did. He was Chuck fucking Bass. She'd seen him with a new conquest every week since they were thirteen. But ever since their first night he made sure she never knew, and she made a point to never find out, just as he never asked how she felt about Nate, and now he was ten metres away, looking at her as a thin, pretty nobody attached her mouth to the side of his neck.

She felt ill, remembering how he tasted there, how the spot behind his ear smelled like the L'Occitane soap in his bathroom and something spicy. She tried to breathe, forcing a smile at Kati, Hazel and Iz, laughing a little too late at their barbs, and then tried to remember that she was Blair Waldorf, not some weak, pathetic… girlfriend. When she glanced at him he was drinking the rest of his scotch, his jaw tense as he swallowed. When his companion turned his face to hers for a kiss she looked away.

Motherfucker. Arrogant, self-absorbed, over-sexed prick. God, she hated him.

She pointedly ignored him for the next fifteen minutes, waiting for him to do the only smart thing and leave, instead of just sitting there and watching her and feeling up his date in front of her.

Hazel suddenly narrowed her eyes, eagerness in her voice. "What is he doing here?"

Blair followed Hazel's gaze to see Nate walking towards Chuck's table and wanted to disappear, making a show of turning away with ostensible disgust. Nate hated going to these places, usually. Seeing him was bittersweet, a disquieting mixture of familiarity and sadness. It made her chest hurt.

Could this night get any more horrific?

She could tell Hazel and Kati were enjoying her discomfort, waiting for her to react, wanting her to bitch and get upset, like watching a car crash in mid motion. Chuck was gazing at her fixedly, his smile not reaching his eyes as Nate spoke, Chuck's date giggling and sipping her champagne. Blair returned his gaze coldly, before turning to Kati.

"Get me a Bellini," she said, flashing an imitation of a smile and leaving no room for objection. Kati slinked off and Blair looked at the other two, hating the derision on their faces.

"I thought guys liked girl-girl-boy," Iz mocked. Blair twisted her lips into a smirk, trying to figure out the best possible outcome to this steadily worsening night. She imagined herself tucked safely in bed, Chuck and Nate long gone and out of her mind, and wanted so badly to be there at that moment and fast forward through all of this. But she had a feeling she wasn't going to get any rest tonight.

"I'm going to the bathroom," Blair said, needing to get away, to come up for air for a while, and put a hand up when Isabel stood to follow her. "By myself."

She picked her way through the crowd, relief beginning to seep in already, hands clenching as images of Chuck and the brunette replayed in her mind, filling her with revulsion.

Suddenly a strong hand grabbed her arm as she neared the ladies room and pulled her into a dimly lit corridor, her back against the wall, his hard chest against hers.

Chuck smirked at her, his face in shadows, his presence even more overwhelming than usual. "Wasn't expecting to see you, but it's a pleasure nonetheless."

She glared at him icily. "Get out of my way," she bit out.

Chuck had been prepared for her anger, but not her coldness. Blair burned hot, not cool. He threaded his arm around her waist and pulled her hips tightly against him, their faces almost touching.

"Jealous, Waldorf?" he whispered. He knew he was in dangerous waters, because she was looking at him with loathing in her eyes, but then, even as a boy he had never been able to stop himself from stepping into a mess and turning it into a disaster. He pictured his father's angry face, red from frustration. You just couldn't stay out of the way, could you?

Blair laughed hollowly. "You actually think you're worth getting jealous about? Get over yourself, Bass." She tried to move past him but he didn't loosen his grip, looking at her darkly, refusing to apologise for who he was.

"Right. This isn't you out for blood," he said, feeling her hot breath on his lips. He wanted her even now, angry, hating him, it didn't matter.

"No, I just didn't need Nate ruining my night," she shot back. Blair knew as soon as she said her ex's name she had hit a nerve. Chuck narrowed his eyes at her.

"Yeah, I think you will be jealous when I fuck her tonight," he said evenly, his words harsh. "You won't be able to stand that it's not you."

Before she realised she'd lifted her arm, her palm made sharp contact with his face, the skin on her hand stinging. Chuck barely registered the shock before bringing his lips down on hers brutally, her back hitting the wall hard.

Blair yanked her mouth from his and pushed him away, enraged. "You don't get to touch me. Ever."

She wasn't his, never was, never would be. He didn't get to have her when he wanted, expecting her to roll over and take it on his terms. And screw him for thinking he could.

She felt a cut on the inside of her lip and Chuck noticed as well, his hands moving up to her face to pacify her. Blair shoved him away instead and made her way to the door, just needing to get out, hearing him call after her. She had never felt so grateful to see a cab when one stopped in front of the hotel to drop off its fare, slipping inside after them before Chuck could catch up, a few seconds behind.

When it pulled away from the kerb she felt the tears start to rise at the back of her throat, and she forced them down, swallowing hard. She drew in a steadying breath, willing her heart rate to slow. He wasn't worth her tears.
