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

Notes: For everyone who has written such encouraging comments along the way. I am so utterly grateful. There are a few scenes from Hi, Society in this part, which served as inspiration for this fic :)

The Sterling Memorial Library is at Yale. The Alice & Astrid nightie looks like this: .


"So hey, has Blair mentioned who's escorting her?" Nate asked as they walked to Prescott Dance Studio to rehearse for the ball.

Chuck frowned inwardly. "Why? Are you having remorse sex fantasies about your ex?" he asked mockingly.

"What? No," Nate said defensively, unconvincingly.

"Don't eff with an eff-er, I know that look," Chuck said pointedly, as a small knot of worry began to form.

"No, man, it's just every time I see her lately something's different, you know? She's lighter, she's happier…" Nate exhaled, clearly disconcerted. "She's just less… less Blair."

Chuck couldn't stop the corner of his mouth from curling upwards. Yeah, Blair was very happy. He made sure of that. As often as possible.

"She does have a certain… glow about her, doesn't she?" he observed with a smirk.

Nate had always been completely transparent, and had a habit of falling for every pretty girl who flashed a smile his way. The problem was that once he caught one he never knew what to do with her. So Chuck hadn't counted on him being interested in Blair again, considering how long he'd pined over Serena while Blair was ripe and willing in front of him the whole time. His best friend had been a fool, and he was going to reap the benefits of his mistake for as long as he could. He wasn't ready to lose Blair just yet, not when things were going so well. She'd been everything he could ask for - somehow it had been Blair Waldorf for him all along, and he too felt lighter… and happier.

"It's just, I haven't seen her like this since before her dad left. I mean, I know things weren't perfect between us," Nate conceded.

"Understatement," Chuck said wryly. "You could barely get it up for her."

"But with my dad in rehab it's like the pressure's finally off me, you know, I can see Blair clearly and it's…" Nate let out a sigh of regret, confused. "I don't know, man. I think I might miss her."

Chuck felt his throat tighten at his words, the knot rapidly growing into total apprehension at the thought of Nate screwing all of this up for him. Blair would always have a soft spot for his best friend considering their long history, Chuck knew that, but it could very easily turn everything on its head.

He scoffed dismissively, attempting to appear persuasive. "You don't miss her, man." He stepped into the studio, wanting to put as much distance between them as possible.


After the rehearsal Chuck arrived at Blair's apartment, finding her lounging on her bed with one red-stockinged leg crossed over the other. He removed his scarf and blazer, tossing them over the back of her chair. She watched his movements with a slow, appraising flick of her eyes.

"My, my," he drawled, walking towards her. "Someone can barely keep their panties on."

She pulled him down impatiently for a kiss and he followed easily, settling on top of her, hips nestled comfortably between her legs.

"Took you a while," Blair murmured, untucking his shirt to get to skin. Lazy afternoon kisses with her secret… whatever he was, were definitely high on her list of favourite things lately. They'd both planned to skip out early on rehearsal to allow for more time, but Nate had asked Chuck for a lift home, saying he had to attend to something important.

He nibbled on her lips, pulling her leg higher around his waist and grinding his growing erection against her. "I was… regrettably detained."

Blair squeezed her legs, moving against him, giving herself over to his kisses. She loosened his tie and the top button of his shirt, kissing his neck. Normally her underwear would have been on the other side of the room already and Chuck's pants tangled around his knees but they were both content to explore each other's mouths, nipping and teasing between long, slow kisses.

"You looked pretty hot on Princess Theodore's arm today," Chuck commented, looking down at her with desire in his eyes and his bottom lip between his teeth. She felt the heat rise higher inside her. There hadn't yet been a single time when her body didn't respond to him like a natural reflex, softening and yielding, her skin tingling in anticipation.

"Oh, is that what I am to you? Just an accessory?" she asked with a teasing smile, her voice soft and breathless from his kisses. Chuck loved hearing that voice, and moved to capture her lips again. When he was with her like this it was easy to dismiss any concerns about Nate, because the way she was looking at him now, like she didn't want to be anywhere else… Goddamn fluttering.

"Next to him, yes." He twisted her to sit astride him so that her crotch was pressed firmly against his hard length. "On me you'd be so much more…"

His tone was low and husky, turning her insides to liquid, and Blair twisted her hips, increasing the friction between them. She knew things had been different over the past few days, there was something new and fragile that could so easily be crushed, and they edged around it guardedly. Chuck teased her more, touched her more, and when he looked at her with softness in his eyes she had to close them with a kiss, so that she didn't have think about the way it made her feel.

"Yes, but I can't be on you, remember? Because you don't want Nate to find out, we don't want anyone to," she reminded him between kisses, pulling him up into a sitting position. "But you'll have to learn to… behave yourself first," she grinned. Their lips met again playfully.

"Miss Blair, Mr Nate for you!" Dorota called from the bottom of the stairs, the slightest tinge of panic in her voice causing them to cease their ministrations.

Chuck rolled his eyes and flopped back onto her bed with equal parts exasperation and irritation. Blair looked down at him with a slight pout, displeasure on her face. It made him feel a little better, until she started to climb off him.

He pulled her back by her waist, holding her firmly. "What are you doing?"

She looked at him with eyebrows raised, like he was out of his mind. "Nate's downstairs." She twisted out of his grasp, attempting to straighten her hair.

Chuck remained on her bed, his annoyance apparent and clothes dishevelled. "So you're just going to run off as soon as Nate comes calling?"

Blair shot him a look as she searched for shoes, sliding her flats on. "I'm not running off. Just let me deal with this, okay? Don't move."

Chuck didn't reply as she left, closing the door firmly behind her. His jaw clenched. He wasn't her lapdog, and he wasn't going to lose to Nate. If Blair thought she could control him - them - she had another thing coming.


Blair called his cell as soon as she had returned to her room only to find him gone, and by that time he was halfway back to his hotel, an 18 year old Highland Park single malt in his glass to calm his nerves.

"I'm just going with him as a favour, that's all," she interjected before Chuck could open his mouth. He would have been amused if he wasn't so disgusted by them all, himself included.

When he didn't say anything Blair rambled some more, not sure why she felt she had to explain herself to him.

"It's not like it's a date or anything, it's purely platonic. It's not even a big deal."

She remembered when Chuck had half-jokingly suggested that he should escort her to the ball, the way she'd laughed in disbelief and shot him down immediately, telling him she already had an exceptional escort lined up and did she look like a crazy person?

Blair bit her thumbnail. "Say something!"

Chuck finished his scotch with a fortifying swallow. "I'll send the car around tonight at nine."

She didn't want to look too deeply into why she felt so relieved, and told herself everything was going to be okay. She could handle this.

"See you then," she said, before he hung up.


She was furious at him. So furious she was practically shaking with it. Not that he hadn't given her good cause, arriving at his hotel two hours late with Chanel No. 5 pervading his clothes and reeking of booze laced with secondhand smoke. He had three missed calls on his phone. Blair was on her way out, grabbing items of clothing she'd left from previous nights and stuffing them into her bag.

"What do you think you're doing?" he said from the doorway of his suite, still buzzing from the bottle of champagne he'd consumed earlier. He could still taste - Alicia's? Alana's? - cheap lipstick in his mouth, like he'd swallowed a bar of soap. The whiskey he had shot back in the limo hadn't helped.

She yanked out a garter belt from his underwear drawer, slamming it shut. "Leaving."

Chuck came up behind her, enfolding her small waist in his hands and pressing his lips to the flushed curve of her neck. She didn't relax into his arms as she usually did.

"Now why would you want to do that?" he asked unhurriedly, placing moist kisses against her skin.

Blair pushed him away and stepped back, her face hard. "Because I've finally come to my senses and realised that this," she said, gesturing between them with a disgusted look, "is utterly pointless."

Chuck could tell he had hurt her, and he'd wanted to hurt her, it came so naturally he didn't even have to think about it. And the worst part was that he'd let her so far in she knew how to hurt him too.

He looked at her with a stony expression. "We both know that's not true."

Blair's voice was filled scorn. "Please. This little game is getting tired, don't you think? Even if there was the smallest chance that it could be anything remotely more than that, what does it matter? I obviously can't trust you."

He smirked at her, pulling her up against his body. "You don't really care about that."

"We should just cut our losses before it's too late," Blair said, looking up at him with weary eyes.

Chuck hated that look. It smacked of defeat, and he wasn't done yet. Not even close to being done.

"Since when do we play it safe?" he asked, a little harshly.

When she didn't move out of his arms he lowered his head to kiss her softly, then kissed her again when she didn't object, teasing her lips gently until she slowly began to respond, returning his kisses guardedly.

He dropped her bag onto the floor and kissed her harder, hands holding her face. He was exhausted, from both Nate's interference that day and trying to resist her all night, and he just wanted to disappear into her skin, because she always won in the end.

Blair pulled back, changing her mind with a shake of her head. "Chuck, no…"

"Blair," he said, forcing her to look at him. "Just shut up and let me kiss you."

She stared at him for a long moment before lowering her eyes. He captured her lips roughly as her hands pulled him closer.


Chuck woke up to soft lips pressing kisses against his shoulder, and a warm, smooth body on top of his. He smiled sleepily, Blair's dark hair tickling his chest. He could wake up like this every day. She bit him gently, teeth nipping skin, moving down to his stomach. He made a sound of pleasure, alerting her to his wakefulness.

"Don't think for a second that you've finished making up for last night," she said to him with an eyebrow raised, looking beautiful and young in the morning light, her face washed free of make-up. The sight of her made his stomach tighten, and Chuck decided that out of all the ways he loved seeing her, this was how he liked Blair best.

He remembered her anger the night before, the way she had clawed at his skin hard enough to leave welts, bruising his lips with her teeth.

"What is it?" she asked, bringing him out of the memory, looking at him with a frown on her face. His eyes had turned distant and moody. She was meeting Nate in a couple of hours at the tailor for his fitting and she didn't want to leave without things being settled.

Chuck looked at her, his face clear. "Nothing. Any special requests?" he asked, wrapping his arms around her waist as he pulled her up, their faces inches away.

Blair looked at him thoughtfully. "Surprise me, Bass."

At her challenge he threw her on her back as she giggled with pleasure, arms drawing him down for a fervent kiss.


Chuck watched languorously as Blair pulled her clothes on hastily, looking around his room frantically for her other shoe. He was entirely too self-satisfied to care that she was rushing off to meet Nate, considering he'd made her come four times in his Jacuzzi bathtub - her slippery back pressed against his front, cock thrusting deep inside her, fingers rubbing her clit and pinching a hardened nipple. And twice afterwards until she finally had the presence of mind to untangle herself from his sheets.

"I'm so, so late," Blair complained, her legs still shaky and feeling harassed. "And I can't find my shoe!"

There were clothes all over the floor and she tossed them around uselessly, looking for her Ferragamo heel. Her phone buzzed on the nightstand and Chuck reached over to flip it open. Nate had sent her an enquiring text, asking if she was still on her way.

"Nathaniel expresses his concern," he reported with a smirk.

She scowled as she applied her mascara. "Don't touch my phone."

Chuck found a joint in his bedside table and lit it, inhaling the smoke, muscles tired and spent. He was starving after their morning activities and considered the room service menu. He looked up as she curled her hair impatiently, scrutinising her unkempt locks in dismay as she tried to make herself look the part of Blair Waldorf and not some thoroughly ravished wanton. She'd forced him to get a curling iron for his bathroom soon after her birthday, threatening not to stay the night otherwise.

"Sure you don't want breakfast before you go?" Chuck asked casually from the bed.

Blair gave him a harried look. "I have serious bedhead," she said mournfully.

He shrugged, rubbing his neck. Her loss. "I can't believe you bit me so hard."

She snickered. There were visible teeth marks on his skin, though faint, and they would fade before the day was over. "You spanked me!"

"And you loved it," Chuck replied. She finally gave up on her hair and gathered her things, no time to even look for her headband. Nate had seen her look worse. Probably. She checked the time on her phone.

"Shit. I'm so late… God, my shoe," she exclaimed, finding it wedged under the sofa. She sat down to strap them on and Chuck eyed her skinny jeans appreciatively. Blair rarely wore jeans, preferring skirts and dresses, and they hugged her form enticingly.

He finally got out of bed, still nude, taking a long drag from his joint as he walked over to her.

She watched him, a small smile playing on her lips, and he smirked. "See something you like?"

Blair's playful eyes met his, before drifting downwards. "Perhaps. I can't believe you're getting high this early."

Chuck smiled devilishly. "I've had a very good morning."

She reached out to caress his cock, closing her fingers around the thick base, and it rose with interest. She loved the way he responded to her, it made her feel… sexy, desirable. Then again, everything Chuck did made her feel sexy.

"Blair…" he said huskily, eyes darkening.

She pulled him closer and placed a wet kiss on the tip, feeling him harden even more. Then she gave him a long, luxurious suck that had him squeezing his eyes shut, mouth falling open with a low groan as her throat relaxed to take him in. All the way.

Chuck let out a breath. Yeah, Blair was definitely made for him.

She looked up at him coyly, hand stroking him slowly but firmly. "I really, really have to go."

"Mm," he said, not listening, all of his concentration fixed on what she was doing to his body, the joint in his hand forgotten and burnt out. "Oh… god. I love when you do that."

She gave him a couple more leisurely sucks before standing up, hand on his ass and tongue in his mouth.

"I'll see you later," Blair smiled against his lips, skipping out of his suite with a grin and a wave before he could catch her.

He threw the joint on the floor. "Fuck, Blair!"


"Everything all right, Mr Archibald?" the manager asked as Nate adjusted his tux, checking the sleeves.

"Yes, everything's fine. It's just… my date, she's never late, and she likes to have final approval--"

"Sorry! Sorry sorry sorry," Blair said as she rushed inside, out of breath. Nate looked at her questioningly and she blushed, excuses tumbling from her mouth. "My cappuccino was decaf and I couldn't find my phone! Took forever to get a cab."

"But you live up the street," Nate said, a touch of scepticism in his voice.

"I wasn't home," Blair said simply, and he let it go. Her phone jangled and she flipped it open to read the message.

R u with him rt now?

"Well, everything's taken care of," Nate announced. "I'll pick you up at five in the car. I got that Laurent-Perrier you like," he smiled, checking to see if she approved.

Why? she texted back. Miss me already?

"I also thought we'd stop by The Modern afterwards for dessert. 'Cause that's your favourite," Nate continued, knowing how much Blair adored being wined and dined, and he hadn't done something special for her in a very long time.

After that stunt… Ur room, 10 mins.

Nate's expression dropped. Normally Blair was all eyes for him and loved when he turned on the romance, flashing him her sparkling eyes and luminous smiles. Now she wasn't even listening, eyes glued to her cell, smiling to herself.

He knew that smile. He'd seen it countless times when they were together. He hadn't even considered that Blair would be dating already; he was so used to her being on his arm with zero interest in being elsewhere. It was a little bewildering.

Gonna spank me again?

"Blair," he called firmly, getting her attention.

Her head snapped up, surprised, as her thumb hit 'send'. Cotillion. Dessert. Right. Except that after the ball she was having Chuck for dessert…

"Oh. Um. We don't have to go anywhere afterwards, that's fine," she smiled lightly, hopping off the bench she was perched on and dropping her phone in the process.

He bent down to pick it up for her as it chimed again, it had not stopped since she arrived. He frowned. "Who's texting you so much?"

"Serena," she lied stiffly. Nate saw through her lie easily and she looked away, checking the message quickly. "Uh, I gotta go back to my house. My mom is supposed to throw this tea for Serena's grandmother and she had to jet to Paris at the last minute so it's all on me," she said, rolling her eyes.

She moved around him in an attempt to escape, thinking about Chuck waiting for her in her bed, her mother away, his lips on her skin… god, his lips--

"Okay. Oh hey, I'll stop by and help you out--" Nate suggested, knowing how she loved it when he showed an interest in helping her with her soirees.

She quickly rebuffed him with a smile, "It's all right, I got it. Thanks."

Nate stood there, stumped, as she turned to leave. "Who are you and what did you do with Blair Waldorf?" he asked, incredulous.

Blair stopped and finally looked at him for the first time that morning as if realising why she was standing there. She admired the cut of his tux.

"Not bad, Archibald. I almost forgot how handsome you are," she remarked sincerely. Nate had always shined brightly, disarming her with his perfect smile, his sincere eyes. He and Chuck had always been polar opposites.

Chuck. She was still a little sore from that morning but she spun on her tall heels, skin tingling with barely contained excitement.



Blair tried on her gown for the last time, making sure it was flawless, before hanging it up again. She had dreamed about the debutante ball ever since she was thirteen, envisioning herself on Nate's arm, gliding around the ballroom in her princess dress with the cream of society looking on in admiration. It was a nice dream.

She washed off her makeup and heard her cell phone ring, darting into her room to pick it up before she missed the call, and a smile touched her lips when she heard Chuck's voice, his tone low and relaxed.

"What are you wearing?"

"What's it to you?" she smirked, walking to her bed and pulling the sheets back. It was almost midnight and she had planned to sleep early so she was refreshed for tomorrow; her nightly routine had taken close to half an hour.

"I've been sent to trawl your waters. By your ex, of all people. He wishes to know why you look so very... satisfied lately," Chuck said, his teasing voice making Blair wish he was with her in person, his lips tickling her ear.

"Oh, really?" she smiled, leaning back against her pillows. She had to admit, having Nate on her heels again did wonders for her ego. "Dig up anything?"

"Well, a certain roguishly handsome billionaire might have come under the radar..." he said offhandedly.

Blair smiled to herself, pretending to think. "No, doesn't sound familiar. My mom did make me the perfect dress for tomorrow..."

"Hmm," Chuck mused, "I don't think that's it."

"Maybe it was the amazing crème brulée I had last night," she suggested.

"No. Not that either. Though I will pass on your sentiments to Justin," Chuck said, referring to his chef at Gilt.

"Then I have absolutely no idea," Blair smiled. "And you already know what I'm wearing."

"Probably," he said, taking a sip from his drink, continuing in a conversational tone. "You're not with me, so I'm going to rule out naked. Pity. And you're probably already in bed."

"Good so far," she said, snuggling into her sheets.

"You wore that black Donna Karan last night, so tonight... the Alice & Astrid?"

Blair laughed softly. "You know me well." He'd bought the silk nightgown for her a week ago, and she had thanked him with a lap dance that had ended with his tongue tracing the alphabet on her clit. She couldn't deny he was a giver.

"Of course I do," he said. She didn't respond to his words, wondering if there was anything Chuck didn't know about her.

"So tell me what you have planned after the ball," Blair said, changing the subject. She had been looking forward to it all week and had only managed to find the perfect basque in French lace that afternoon. Chuck would go crazy over it, though she did hope to wear it for longer than five minutes.

"You'll have to wait and see," he said. He looked at the tickets in his hand, return flights to Barcelona with their names printed in black and white. "I have another surprise."

She raised an eyebrow. "Full of surprises lately," she commented.

Chuck smirked. "You'll like it, I guarantee it. Even more than the last one."

"Hmm. Difficult, but very possible." Blair switched off her bedside lamp, closing her eyes in the darkness. "I'm so excited about the ball, I don't think I'll be able to sleep."

"Well, if that's the case—" He began with a leer.

"No," Blair said firmly, knowing she'd set herself up for that one. "I need my beauty sleep, Chuck. If you come over we'll be up all night."

Chuck smiled into the phone, filled with affection for her. "Waldorf, you flatter me. But I was merely suggesting that I help... tire you out. "

She rolled her eyes. "Concerned for my personal well-being, I'm sure."


"I think I'll be able to manage without you," she said with faux politeness.

"Really? What are you going to fantasise about tonight?" he grinned. "The one where we do it at the Sterling Memorial Library?"

Her mouth opened in shock. How did he know that? "You think you're so funny."

"In the limo?"

Blair made a sound of annoyance. "I'm hanging up now, Chuck."

His laugh came low and rich through the receiver. "I love it when you're angry."

"That's because you're a sadist," she said pointedly.

"You wound me," he objected. He was about to comment on how much she loved a good spanking, but thought better of it.

"I didn't think that was possible," Blair quipped. "The Tin Man never had a heart."

He stared at his drink absently, the ice slowly melting and creating tears of condensation on the glass. "Though as I recall, he didn't like hurting butterflies," Chuck said, his mood suddenly becoming serious.

Blair opened her eyes in the darkness, feeling uncertain. "No, he didn't." She glanced at her clock, it was after twelve. "It's getting late."

"Just tell me one thing before you go," Chuck said, sounding hoarse and strange, enough to make her hesitate.

"What is it?" she asked cautiously.

"Tell me you still want Nate," he said quietly. "More than you want me."

The silence seemed to stretch on for minutes, although Blair knew it was only seconds. She swallowed, throat closing up suffocatingly, unable to formulate a reply and not trusting her voice. He knew the truth. Why was he making her say it, what would be the point?

"I have to go to sleep now," she said abstractedly, heart thudding in her chest. "I-- I've got a lot to do in the morning and the Times will be here early."

He paused, then seemed to change his mind, allowing her to escape. "Of course. I'll see you tomorrow, Blair."

"I'm wearing the Erickson Beamon necklace with my dress. They go together, don't you think?" she asked quickly, biting her lip.

Chuck smiled humourlessly, and it pained him somewhat. "It's perfect."

"Thanks," she replied softly. "Goodnight, Chuck."

"Save a dance for me tomorrow," he said.

Blair heard the click as he disconnected and her breath hitched. There was a cutting silence like one of her limbs was severed from her body, and she was suddenly overwhelmed by the rapid beats of her heart fighting against the confines of her chest, vehemently making itself known.


Note: Many apologies for the abrupt ending, I feel like some people will be disappointed, but I tried to fit this around the show as realistically as possible. You know the rest by heart. I hope you enjoyed reading this as much as I enjoyed writing it. Reviews are love 3
