A/N:

What the fuck is this, you ask? Well. Let me tell you.

Darcy and Sienna have had their little side plot throughout this entire story, so I've had my own secret ideas about everything that's been going on with them behind the scenes. There has been lots of speculation about Darcy, about how good he may or may not be in bed, about the size of his penis... All valid inquiries, I recognize.

In the comments of the last chapter, I confessed the contents of a specific, raunchy, R-rated scene I had envisioned featuring Darcy and Sienna, and I wrote out some parts of it to tease my readers in the comment thread, and then I realized that I needed to write it, like, right now.

So, without further ado, here's a smutty piece of Darcy x Sienna madness. It would take place sometime around May of the same year H&M is currently set in. A quick reminder that Canadian universities typically have spring/summer break from the beginning of May to the end of August.

Warning that this is... explicit. Darcy is a dirty, dirty boy. If you aren't into sodomy, I apologize in advance.

I did this partially to say thank-you, because I asked you guys to please comment more last chapter and god damn it, there were close to 1K comments and it made my life to hear from so many of you. Your reactions and feedback and thoughts are such a huge part of my motivation, so thank you! ILYSM.

Make sure to let me know how you liked this one. It's an extra, extra long one... 😏

Enjoy!

How the fuck had they ended up here? One minute, they were eating dinner with their families in the dining room of Darcy's house. Then, the parents started drinking and joking and so, everyone under forty decided to leave them to their indecipherable inside-jokes and unfortunately inappropriate humor. Like, fuck. If Darcy had to listen to Aunt Vic make one more not-so-subtle reference to the size of Uncle Dylan's dick...

He also didn't want to think too hard about whatever the fuck his sister and Luke were up to in Ophelia's bedroom across the hall. They were a couple of love-sick puppies and it was practically nauseating.

Jason was at another friend's house tonight, lucky bastard. And so somehow, after the angst-ridden glances and tension-filled silences and snide, bitter remarks he and Sienna had been exchanging all evening, they ended up standing with their bodies pressed a little too close together in the hallway outside Darcy's room, because they had things to talk about, or yell about, or whatever.

Darcy knew he was treating her like an ass, and he also knew he had no good reason for it, except, everything she did just made him so goddamn frustrated these days. Her and her stupid boyfriend. Pretending she was happy with him, that she actually liked that loser. And it irked him even more that she was lying about it, because they both knew the truth.

Oh yeah, that's how this had all started. Her taunting him, saying that he looked like he had something shoved up his ass, and him retorting that pegging wasn't his kink, but that he'd be happy to oblige her, if she wanted to see what it felt like to have something stuffed up hers.

And fuck, he shouldn't have even brought it up, because the thought of bending her over and taking her that way made his dick way too fucking thrilled about it.

What he didn't expect was the unmistakable look of arousal that swept across those pretty features, the way she looked at him, as if the very idea had her fucking dripping for him.

Of course it did. She was such a dirty girl.

But hell if it didn't surprise him when, in the shadowy corridor outside his bedroom, she craned upwards and whispered into his ear, "I have been thinking about trying it out... Wanna help me with that?"

A low growl vibrated against the back of his throat. She was fucking kidding, right?

Yeah, of course she was kidding. She was crazy. And such a fucking tease.

He shook his head, let out a huff of disbelief, twisted open his room door and walked away from her, because fuck, did she always have to send him so many mixed messages?

And, completely unsurprising to him, she followed after him, shut the door behind her, plopped her tight ass down onto his unmade bed. Fuck, it had been a while since the last time he'd seen her laying there in his bed. She always looked good wrapped in his sheets.

"Please, Darce..." She sat on the edge of the mattress, legs crossed to exposed the creamy skin of her slender, toned thighs. She tilted her head to the side, chewed on her bottom lip with a look of complete, deceptive innocence plastered across her face. "Don't you wanna fuck me in the ass?"

"Fuck, Sienna..." He ran a distressed hand through that thick mess of golden-brown hair, his hungry gaze devouring the sight of her perched at the edge of his bed in that tiny excuse for a dress, begging him to fucking... ruin her. "Are you gonna break up with that fucker? What's his face. Clive. Bet he doesn't even know where your asshole is, Sienna."

She rolled those stormy grey eyes at him. "His name is Kyle, dipshit. And he's... nice."

Darcy leaned back against his dresser and crossed his arms, quirked an eyebrow, unimpressed. "You're not nice, Enna. You'll never be satisfied with a guy who's just fucking... nice."

"Yeah well, he's good to me." She propped her hands back against the crumpled duvet and speared him with her fiery gaze. "And he isn't afraid of commitment, like some people..."

Darcy snorted, narrowed his eyes. "You're asking another guy to screw you in the ass, babe. Look who's talking."

"He's doing a semester abroad over the summer, Darcy. We're taking a break while he's away." She gave him that look, that sweet, pouty, innocuous look that fucking killed him, every goddamn time. "So I figured I'd finally try it out, with someone who knows what they're doing, but..." An indifferent shrug. "If you don't want to, I'll just go find someone else..."

In a couple long strides, he eliminated the distance between them, came to stand a foot in front of her, towering over her. She didn't even flinch at the darkness that had clouded over those ocean blue eyes, the pissed frown that captured his smooth, tanned forehead. "Stop pretending," he murmured, slow and dangerously low, "That anyone gives it to you the way I do, Enna. We both know that's such a fucking lie."

For a second, there was just a hint of vulnerability, a flash of something less daring across her face. But then she tilted forward, peered up at him defiantly and countered, breathlessly, "Then don't fucking pretend that I don't mean something to you, Darcy. I'm so damn tired of your stupid games."

And he paused, mouth open, ready to bite out an empty retort, because he knew she was right. He knew that he was the one who kept playing it cool, who said he didn't want to be held down, didn't want something serious. Who said they were both still young, that he just wanted to have fun, except, she was driving him so fucking crazy. He wanted it both ways. And even if he didn't wanna admit it, he knew it didn't work that way.

"Clive's never fucked a girl in the ass before?" He tilted his head to the side, looked down at her, at those plush pink lips that were just a few inches away from his dick. Fuck...

"It's not his thing, I guess," she shrugged. Ha. Darcy'd bet the poor guy would piss himself at the mere thought. What was she even doing with someone like him, anyway? Someone who couldn't... satisfy her. Christ, it drove him insane, because... well, fuck.

She wasn't his anymore.

He reached out, swept a large palm against the side of her face so his long fingers tangled into the silky blonde waves of her hair. His thumb brushed softly up and down her cheekbone, and he felt the way she leaned into his touch. Fuck, her skin was so soft. Always so fucking soft.

"You mean it?" he grumbled, meeting her eyes with something glinting wickedly in his. "You want me to bend you over and shove my cock into your ass?"

Her lips parted and her breath hitched and a pretty pink flush flooded her cheeks with heat. "Yes. God, yes."

The pad of his thumb drifted forward to caress the full flesh of her mouth and he murmured, gruffly, "You gonna beg me for it?"

Those stormy grey eyes tapered off into defiant slits. "Why would I beg..." And then she brought one of her small hands up to palm him through his jeans, "When you want it just as bad as I do?" She gave his erection a firm squeeze that tore a grunt from low in his chest.

He grasped her wrist, pulled it away from him and gave her a shove, back onto the bed, so she lay with those golden strands of hair splayed out across the wrinkled navy comforter. Her short dress rode up high on her thighs and she gazed up at him with hooded, sparkling eyes. She loved it when he was rough with her, and he bet that Clive was never rough with her. She slid back to the center of the bed and looked him right in the eye as she spread her legs so the thin fabric of her light-grey skirt fluttered around her belly and a lacy red pair of panties became visible between her thighs.

He created a monster and he fucking knew it.

Briefly, his mind wandered back to that brazen fourteen-year old girl who asked him, all of a sudden, one day, if she'd let her suck him off. Remembered thinking he should say no, but learning that same day that saying no to this girl wasn't ever gonna work.

As he turned away from her to lock the door, he asked, quietly, "You're really taking a break?"

He wasn't gonna fuck her if she was still seeing him. You know. Out of principle.

"He flew out yesterday, Darcy."

And it took her one whole day to come crawling back to him, huh?

He came to stand at the edge of the bed, scrubbed a palm over the lower half of his face. His eyes were drawn to the scrap of fabric between her legs. He watched her and she watched him as she skimmed a hand down her front, over her mound, down to stroke the crotch of her panties, where Darcy could already see the dark, damp spot of her arousal soaked through the thin lace. Fighting with him always turned her on, didn't it? He followed a couple of her long, slender fingers as they dipped beneath the fabric, heard the soft moan that tumbled past her lips when she touched herself, smelled the sudden sweet scent of her as it filled the air around them.

"Fuck, Sienna," he cursed as he watched her bring her glistening fingers up to her face, slipped them into her mouth, gave them a hard, appreciative suck.

"Want a taste?" she taunted, flashing him a coy smile. "Or are you just gonna stand there?"

A rough chuckle fell from his lips and he watched, knowingly, as her eyes widened and flared with want when he tugged his t-shirt fluidly off his head, began unbuckling his belt, slipped it smoothly from the loops of his jeans. "It's been a while since you sucked my dick, huh?"

His pants dropped to the ground in a pool of denim and he kicked them aside, followed her greedy gaze as it floated over the outline of his hardness beneath his black boxer-briefs. Her tongue darted out to wet her bottom lip and she pressed her thighs together, gripped the hem of her dress and shimmied it off her head, tossed it away. And then she was crawling over to him in just that skimpy pair of dark red underwear that made her milky white skin just fucking glow. It had been a while since Darcy had seen her naked and the sight of her nearly bare, right in front of him, set his entire system on fire.

She stood on her knees so they were nearly face to face. Then she hovered her mouth just a couple inches in front of his and shit, when was the last time he'd kissed her? He missed the taste of her. She tasted like... Sienna. Like trouble and strife and mischief and temptation and battle and... fuck. His fingers were in her hair and his lips were crushed against hers so fast and hard that she whimpered into his mouth.

Their hands were all over each other, scratching at skin and tugging at hair and clutching and squeezing and grasping. Feverish and starved and angry. He couldn't decide if he was angry at her or at himself.

She bit harshly into his bottom lip, hard enough for a warm, metallic tang to taint their warring mouths. He groaned, pulled her to him by the hips so she could feel his erection throb against her stomach. Yeah, she was asking for it.

He trailed his hands up her body, fisted her hair in his fingers, ripped her face away from his. "You're fucking crazy, you know that?" he told her, guiding her down, lower, until she was sprawled on her stomach in front of him, soft pants falling from her bruised lips. Her fingers slipped beneath the waistband of his underwear and pulled them down, letting them fall to his ankles before curling her hand tightly around his shaft. A ragged breath fell from him when she rubbed a thumb against his swollen tip, used her other hand to cup his balls. And then she met his gaze and held it as she sucked him into her hot, wet mouth, moaned around him, lashes fluttering shut, like he was the best thing she'd ever fucking tasted.

And he never had to tell her how he liked it, what to do, because she already knew. Because no matter how many other girls he tried this with, they didn't know him, like she did. "Fuck, Sienna... Just like that, baby..." He held her head, guided her back and forth along his dick, groaned at the way her lips formed a tight ring around him, sucking him almost to the point of pain, hard enough to send him into a foggy, blissed-out daze. "Yeah, ah, fuck... So good, Enna..."

So good that he had to stop her, reluctantly, because he had so many other things he planned to do with her tonight and unfortunately, blowing his load down her throat wasn't gonna help. She released his cock from her lips and it strained towards her, still hard and covered in the wetness of her mouth. She rubbed her lips together and told him, "You taste so good, Darce."

"Mm. Lay back," he replied, stepping out his briefs and then climbing onto the bed, on top of her. A kiss to her mouth, where his own dirty taste still lingered, then to her shoulder. A hard suck against the base of her neck, because he wanted her to look at herself in the mirror after and remember him, remember the things he did to her, only him.

Soft breaths made her chest rise and fall as he peeled a bra-strap off one shoulder, kissed his way down her throat, the top of her chest. He reached around her, unclipped the clasp, discarded her bra. He dipped down to pull one of her hard pink nipples into his mouth, kneaded her other breast in his palm, getting high off her breathy sounds, the little hums of pleasure that he drew from her lips with every touch. "Fuck, I missed your tits," he murmured.

"Oh, Darcy," she whispered, her hips arching up to meet him as he snaked a hand down the front of her panties, cupped her, slid a finger through her folds, along her soaked slit. "Please..."

Their lips tangled desperately together as he worked his hand between her legs, pressing, rubbing, caressing, because he also knew. Exactly where that spot was, deep inside her, when he pushed a couple crooked fingers against the slick walls of her cunt. "Always so fucking wet for me, Sienna..."

His thumb traced firm circles over her clit and her hips bucked beneath him, trying to meet his tempo stroke after stroke. But then, when he knew she was close, could feel the way her body was trembling, he pulled away, heard her disappointed, confused sigh echo into his ears. "Darcy..." she whined, but then he was stripping the lacy fabric off her legs, and then his hands were on her hips, flipping her over, pulling her up onto all fours before his fingers found her there again, and so did his mouth. "Ah... ah... fuck, Darcy!"

He smiled against her pussy, his lips coated with her juices, because he wasn't even inside her yet and she was already screaming for him. "You taste... so sweet, Enna..."

And again he was pulling away, and again she was whimpering in frustration, but then his hands were on her ass and a gasp of realization left her lungs. He leaned over her, pressed his lips to a notch on her spine. "Have you ever been touched there before?"

"Just... with a finger, a couple times," she explained, her voice all husky and breathless. "Barely inside."

So all of her firsts, apparently, belonged to him.

He brushed a string of kisses down her back before leaving her for a moment to go grab a couple condoms and some lube from beside his bed.

She grabbed a large pillow, tucked it beneath her upper chest to prop herself up so her arms didn't get too tired. "Hurry up, Darce," she urged. She arched her spine so the soft round swells of her ass stuck out towards him, taunting him.

He held onto one of her cheeks and brought his palm down hard against the other. The loud crack of flesh on flesh rang through the room and the whimper that spilled from her drove him fucking wild. Her pale flesh flushed red from the sting of it. He smoothed a hand over the reddened swell and delivered another sharp smack so her entire ass burned pink. "Does Clive ever spank you like that?" he asked gruffly, reaching between her legs to confirm that she was fucking drenched. "Does he know you like it?"

"His name is Kyle," she corrected weakly, tilting her hips up against his hand. "And he isn't a fucking barbarian like you are, Darcy..."

He pulled away once more so he could squeeze a generous mound of lube onto his fingers, and he couldn't help but smirk a little when she groaned, "I swear to fucking god, Darcy, if you stop touching me one more time—" But whatever menacing threat she was about to hurl at him was drowned away into a strangled moan because his fingers found her pussy again, thrusting roughly into her. His other hand slipped between her ass cheeks to spread the cool gel all over her puckered hole, teasing the sensitive rim of muscle with a sweep of his fingers and making her cry out from the foreign intensity of it.

"I actually don't fucking care what his name is, Sienna," he informed her raggedly. "Because guess what?" He nudged just the tip of one of his fingers into her tight opening while his other hand massaged her swollen clit, glided in and out of her pussy so she was a panting, writhing mess. "He doesn't fucking matter."

"Oh my god, Darcy," she squeaked, "Jesus Christ... angh..."

Fuck. The sounds she made, the way she spat out his name, her breaths and gasps and moans were a million times better than anything he'd ever heard in any porno, and the thick, musky smell of her was more intoxicating than any amount of weed he could smoke, any number of shots he could knock back. Forgetting about her was fucking impossible when she was the highest fucking high he'd ever tasted.

"Tell me if it doesn't feel right, okay?" he mumbled, gentler, fluttering kisses onto the smooth, soft expanse of her back, nuzzling her lower spine so the golden-brown scruff of his jaw scraped against her skin.

"I'm so close, Darcy," she whimpered. He stroked her clit harder, faster, fucked her deeper with his fingers, and then, when he felt her finally start to clench around him, he pushed his well-lubed finger slowly but steadily all the way into her ass and she just fucking shattered, rippling and shivering and gasping, cursing him name in a garbled mess and collapsing onto the bed beneath her.

He gave her a few moments to recover before nudging another finger against her second hole. He removed his other hand from between her legs, leaned over her to push back some of her sweaty hair, pressed a tender kiss beneath her ear. "You did so good, baby," he murmured. She felt so, so fucking tight around his finger and he was starting to doubt he'd ever be able to get his dick into there. "You need to relax for me though, okay? Otherwise this isn't gonna work."

She exhaled a sigh of agreement, turned her head towards him, searching for his mouth. He held onto her throat and she lifted herself up again and their lips twisted together, her tongue sliding against his, more tenderly, more docilely than before. "Add another finger, Darcy," she requested, pushing back against him. "It feels okay."

He let go of her neck to search for the lube, squirted another dollop onto the space where his finger was lodged inside her. "So tight, Sienna. Fuck, you're gonna feel so good..." He listened to her heavy, measured breathing, watched her face as he carefully prodded a second finger against the first, squeezed it in, saw her breath catch, her arms shaking. "Okay?"

"Mhm..." She nodded, her teeth piercing into her lower lip, her eyes sewn shut. "I... want you, Darcy. Inside me. Please?"

Fuck, fuck, fuck... "I have to take it slow, baby," he groaned, bowing forward to kiss her again. "It's not gonna feel good if I rush."

"You always feel good inside me," she breathed. Fuck, her voice was just too damn sweet. So deceptively sweet. "I miss it, Darce." She swallowed and then admitted, barely audible, "I miss having you in me, Darcy..."

A tortured moan fell from his mouth onto hers. "I miss it too, babe. Fuck, I miss being inside you..."

He was so fucking hard right now it was making him dizzy.

His fingers drifted back between her legs, teased her folds as his other hand began to move slowly, in and out of her. He pressed down, against her vagina, because he knew that would feel better. The sounds she was making were high-pitched and guttural and he was trying to take it slow but her ass was spread for him and she wanted it and, they needed to hurry the fuck up anyway before someone came knocking on his door, so...

"Please, Darcy..."

"Fuck, okay. Just a sec..."

His hands were a sticky mess as he tore open the condom, rolled it on, smothered it with a shit ton of lube and then gently smeared more gel along her ass crack.

She tipped her round, smooth, perfect ass willingly towards him and hoarsely begged, "Fuck me, Darcy, please. I want it so bad..."

"I want it too, Enna. Fuck..." He swept a hand beneath her, along her ribcage, tweaked a taut nipple, then the other, bit softly into her neck and grumbled, low and throaty, near her ear, "You're so fucking dirty, Sienna. Letting me fuck you in ass... Fuck. Are you still wet for me?"

"Mhm," she nodded. "You love it, Darcy. You love it when I'm fucking filthy for you. Only for you..."

"Only for me," he agreed raggedly. "I love it, Enna." And then he was lining himself up against her, the tip of him settling against her there, where no one else had ever had her before. Because she was his, no matter whoever else she used to try and forget about him, no matter whoever else touched her. They didn't fucking matter, and they both knew it. His his his...

He found her clit again, worked her up until she was squirming and breathless, 'til he knew she was aching for more. And then he pushed just the head of his cock into her, just an inch, just a little, watching the way he stretched her, the way her ass spread around him. "You feel so good, Sienna. You're doing so good, baby. Feel okay?"

"Yeah..." she breathed tentatively, sucking in some air.

Inch by inch, slow and steady, he pushed himself into her, leaning over her, whispering into her ear that she was such a dirty girl, that she was doing so well, that her asshole felt so fucking good wrapped around his cock, that he loved the sounds she was making, that she was so fucking filthy for letting him fuck her in the ass, that she was brave and that her smell drove him crazy and that she was his, all his, only his.

"Ah... ahh... ahhh..." she cried, gasping, shivering, eyes squeezed shut. Her pussy quivered around his fingers and her clit throbbed against his thumb and her ass clenched so, so fucking tight around him that he could barely think... "Dar... Darc—Darcyyy..."

"Fuck, Sienna... Jesus fucking Christ..." The round globes of her ass shook with every thrust, in and out, in and out. Flesh slapping against flesh, the wet squelch of her sopping pussy rippling around him, her asshole hugging his burning cock. Heaven and hell, pleasure and torture, sordid and debauched and depraved and his.

"You gonna come for me again?" he rasped, holding her in place, groping at one of her tits, giving a hard nipple a quick pinch before rolling over it soothingly with his thumb, because he knew she always liked it rough.

"Darcy, I can't, I... oh, ohh..."

"Yeah, just like that, baby. I know you're almost there, I know..."

"Please, Darcy..."

"Mhm... You're a dirty, dirty girl, Sienna... My dirty girl..."

"Yours, Darcy, yours, I..."

"So good. You're doing so, so well, Enna..."

"Darce, I'm—I'm gonna... ah..."

"Yeah, that's right... Come for me, sweetheart..."

"Ah... Darcy... Darc—"

When he felt her finally, finally tighten around him, a string of tired curses spewed from his mouth and white-hot release jolted through him, violent and consuming and debilitating. She collapsed beneath him and he followed, his head resting against the slope of her spine, his hair plastered to his forehead with sweat, his muscles aching and his voice raw.

"Why..." she eventually murmured, groggy and exhausted, "Do you have to have such a big dick, Darcy? I don't think I'm gonna be able to walk again, ever..."

He chuckled, skimmed a couple tender kisses over the pale, soft skin of her back. "You asked for it."

"I... hate you..."

"I know..."
