It was a cold night, but it was by no means quiet. On that Friday, only a handful of days before Christmas, the city was bustling with activity. Whether it was last minute shoppers trying desperately to find the right gift for their loved ones, or people enjoying the festivities, namely the annual fair that offers a variety of exported goods. For some, however, it was a quiet time, for they were still working despite the sun having set so early into the afternoon. This was no less true for two individuals, who were getting dressed and ready for an office party.

"We're off, you two." A leanly built, appropriately dressed raccoon stood by the front door and looked up as a slender, black-furred feline slowly descended the stairs above, dressed in a slim red dress with a jacket over the top to keep her warm. The raccoon's gaze raked up and down the woman's figure, and as she stopped at the bottom of the stairs he pulled her in, hooking an arm around the small of her back.

"Ugh, dad, save it for the party!" From the living room, another black-furred feline leant over the back of the couch and stuck her tongue out at them through the doorway.

"Don't be childish, Amanda," The older feline teased. "You're 18 now, you know."

The younger cat, Amanda, stuck out her tongue even wider and giggled, leaning up from the couch and rounding its surface as she stepped through the door frame towards them.

"Besides, your mother is beautiful." The raccoon argued and Amanda rolled her eyes, reaching out to hug her mother tightly before doing to same to her dad.

"She is," Amanda assured them, taking in the sight of her mother by looking her up and down. "Gorgeous. You look handsome too, dad."

"That means the world, Amanda." The raccoon offered a wide, toothy grin and Amanda pulled a face, roughly patting his shoulder as she glanced to her mother, then back to her father. Unlike her parents, the black feline was dressed in casual clothes-- her parents were going out to a fancy office party, whilst Amanda and her twin brother were staying inside. Both of them were 18 and didn't need babysitting, but their parents still looked after them nonetheless.

"Remember, money's on the counter for pizza." Amanda's mother insisted and the younger feline groaned, rolling her eyes.

"Mom, it's cool. I'm 18, I can just cook something," She insisted, but her mother's stern look made her wither. "Fine, fine, I'll order pizza."

"Accommodate your brother," She insisted. "And no friends!"

"Yeah, yeah," Amanda waved a hand in mock dismissal. "Everyone's busy anyway, since it's so close to Christmas...me and Sully'll just watch a movie."

Her parents seemed convinced, though Amanda had no indication of lying to them-- she was being truthful when she said no friends were coming over. Though she was something of a social butterfly and made friends easily, she didn't really feel like socialising right now anyway. Sully was the one exception; he was, after all, her twin brother, and Amanda was the type of girl who cared a lot about her family. After a moment, the raccoon checked his watch and whistled, petting his wife on the arm.

"Time to go," He insisted, turning the handle of the front door and pulling it open so that the older feline could step through, after plucking her purse from the little hooks on the wall. "If you have any issues, Amanda, give us a call. My phone will be on."

"I'll be fine, dad. Go have fun!" She insisted, and her father gave her a look before he stepped over the lip of the front door, following his wife down to their sleek little teal-coloured Hyundai i10. Amanda watched them walk down the concrete patio and they slipped into the car, a quiet silence filling the suburban plot for a moment, before the engine rumbled to life. The 18-year-old leant against the door frame and watched as they pulled out the driveway, and her father flashed the headlights at her in farewell before they drove off, disappearing down the street towards the heart of the city. Amanda's parents worked at the same firm and held an office party around this time every year; it was always a lot of fun for them, and Amanda loved seeing them have a good time and get dressed up. With a sigh, Amanda closed the door shut and breathed in the silence of the house for a moment, enjoying the quiet. It didn't last as long as she wanted, for on the floor above she heard a reasonably loud bang, enough to shake the ceiling ever so slightly.

"Sorry!" She heard a male's voice call from above and Amanda groaned, before stepping towards the staircase. She placed her hands on the bannisters and leant forwards, looking up at the floor above.

"Sully! I'm ordering pizza, what do you want?" She called, and there was a moment of silence before a head appeared from the railing above, looking down at her. A messy tuft of black hair framed the man's face and his distinctive banded raccoon face scrunched with confusion. Though Sully was her twin, he had a completely different species from her-- the doctors said it was a 'one in a million miracle'. People often mistook them as just plain old siblings, and usually they didn't try to correct them; only those who were close to them were aware of how close they really were.

"Mom and dad are gone already?" Sully asked, and Amanda wordlessly nodded her head, causing the raccoon to avert his gaze briefly. "The hell, they didn't even say bye..."

"I mean, dad said they were going," Amanda pointed out, watching as her brother's face disappeared before the entirety of him appeared at the top of the stairs, slowly descending. "But enough of that-- what do you want on the pizza?"

"Uh, shit, I don't know," The raccoon bounced his way down the stairs in just a pair of loose boxers and a T-Shirt, headphones wrapped around his neck with his phone stuffed in his pocket. "What do we normally get? Chicken and mushroom?"

"Yeah," Amanda leant against the wall, adjusting her black pyjama bottoms at the hip. "You still good with that?"

Sully's shrug all but confirmed his approval and the feline leant up from the wall, brushing her wavy two-toned hair from her shoulders so that it ran down her clothed back, its tips a bright blonde whilst the rest of it was a warm, tawny brown. As she walked, her chest bounced in her tight shirt, and its front was emblazoned with some slogan or logo that was all intents and purposes didn't matter, and lacked any kind of meaning. Sully followed after her as she went into the kitchen, and he leaned against the island counter as she took the money from its surface, rummaging through a nearby drawer for one of the many different take-out menus they had stashed within.

They didn't deliberate much on their choice of food, and as Amanda spoke on the phone, Sully loitered around the kitchen, looking in the fridge for something to eat. Sully was about as chill as Amanda could be-- whilst the feline girl was headstrong and a little tomboyish, Sully was a stereotypical 18-year-old man, a little immature and horny but otherwise down-to-earth. He wasn't the clout-seeking type, and in any instance would prefer a small gathering over a massive party, but he could be friendly around the right people. In Amanda's often expressed opinion, Sully's best trait was how honest he was about his emotions, and Sully often vocalised himself with actions as opposed to words. To that end, some people considered him 'more mature' than the 'average boy', though he'd be inclined to disagree. As he reached for a snack in the fridge, Amanda batted his arm and gave him a withering gaze, causing him to relent; she could act like her mom sometimes, though she might not notice it.

"Alright, done," Amanda put the phone down and lingered by the open fridge, before gesturing her brother out the way and reaching inside to pick out a bottle of wine. "What do you think? Mom and Dad will be fine with it, right?"

"If you pay for it." A smirk crossed his face as he slid by her, reaching up to the cabinet to pull them out a couple of glasses. Neither of them were the type to drink all that often, but they certainly didn't mind it. He gestured to her and she followed him through into the living room, where they slumped into position on the couch. Sully put the glasses on the little coffee table and reached for the remote as Amanda popped the cork of the bottle with ease, having loosened it enough with a firm wiggle. She poured out a little bit in either glass and then placed the bottle on the counter, leaning back and taking a long and meaningful drink from hers without even swirling it around. Sully cast her a meaningful look, and she noticed, offering him a wry smile.

"I kind of need the drink right now," She sighed. "I've broke it off with Tommy. It just wasn't working."

"Knew it," Sully scoffed. "Always hated that fucker. He made you cry way too much."

"Aww, you're so sweet, Sull," Amanda teased, reaching out to pinch his cheek, and the raccoon shrugged her hand away in response with an amused expression. "Any luck on the dating front?"

"Eh...nah." Sully lied through his teeth. Though he wasn't a virgin, Sully hadn't dated a lot of people-- he didn't see the need, and he was a little too busy to really be paying attention to that sort of thing...at least, that's what he liked to tell himself. The truth of the matter, unbeknownst to Amanda, was that Sully had been crushing on a mutual friend of theirs, a cute rabbit girl called Izzy, for a couple of years. Unfortunately, Izzy had a long-term boyfriend, so Sully's hopes were dashed early and he hadn't been able to get over her since. It was simply easier on most occasions to brush off conversations of dating as him being too busy, usually. Amanda, however, knew her brother all too well-- she'd suspected for a while now that he had a crush, but never pushed it.

"Hmm...fair enough," Amanda eyed him over her glass and took another plentiful sip, gesturing for him to drink as well. "No-one you have your eye on?"

"You know I've been studying a lot to get that scholarship." Sully half-argued with her, leaning over to take his glass so he could glug a plentiful swig of it. It didn't burn, but it left a peculiar feeling in his throat that he often associated with booze. What percentage alcohol was the wine? He hadn't even bothered to check...neither had Amanda, really.

"I know," Amanda pouted. "So have I...but you know, dating and meeting people and having fun is still pretty important, you know? You've got to be social, Sully..."

"Like what you're doing right now?" He saw right through her, and his little quip had her glowering at him, her nostrils flaring as her trail stood on end. The raccoon cracked a smile and she diffused easily, leaning over to slap his knee.

"You're lucky you're my brother, or I'd have slapped you across the face," She pointed out. "But come on, Sull. You've got such a pretty face...you've got dad's handsome genes, you know."

A silence fell between them as Sully awkwardly tried to come up with something in response. It wasn't that Amanda rarely complimented him, it's just that he didn't really know what to think of it. He took another gulp of his wine and quickly realised he'd emptied his glass, and without skipping a beat the black-furred feline reached over to grab the bottle, and he instinctively held out his glass so she could pour more in.

"Uh, well..." He began after she'd topped him up halfway, and took another drink, watching as she filled herself up too. "I mean, you're pretty as well...you've got moms genes, or whatever. I always thought you were too good for Tommy. Potheads are fine and all, but...he was just an ass. Didn't have his shit together. Isn't he failing school?"

"Yeah..." Amanda mumbled, looking down at her glass. "But loving someone makes you do stupid shit."

Silence fell between them again, and Sully once again didn't know what to say. Amanda silently brought her glass to her lips and swallowed mouthful after mouthful of wine, very quickly downing all of her glass. The wine bottle was already half-empty and they'd barely just started talking; Sully thought they were overdoing it, but it didn't seem like Amanda wanted to stop drinking, so he didn't police her on it.

"You know..." She began, her voice already sounding a little slurred from how quickly and heavily she'd drank, especially before having something to eat. "I'm glad I have you here, Sull. You're always so nice, and a fuckin' virgin, and you always defend me over my shitty ex, and it's...it's just great, you know? You're such a nice guy, you deserve a nice girl."

"Uh...firstly, I'm not a virgin, Amanda," Sully chuckled awkwardly and drank some more of his wine, lowering the grass and awkwardly cradling it with both hands. "But it's nice that you say that. I've never really though about having a girlfriend and stuff..."

"You're lying, but it's okay," She drunkenly argued with him and then just as quickly circled the topic back around. "But I still really appreciate your company. You're so sweet and..."

She trailed off and Sully caught her gaze raking over him, looking up and down...he didn't mind, necessarily-- they'd seen each other naked, whether accidentally or on purpose, multiple times-- but this was the first time he'd seen that kind of expression from her, especially with regards to him. With a chuckle, he swigged a bit more of his wine and then set the glass aside, leaning forwards to slowly coax her own glass from her hands.

"I think you've had enough." He remarked, and she giggled, leaning forwards and deliberately fighting against his prying fingers, though she clearly wasn't putting a resistance out of spite, but to tease him. He fought with her on it for a little while, the both of them giggling, before he managed to loosen it from her fingers and leant over to set it aside. When he straightened back up towards her, she instinctively leant in, and he recognised how close she was. His own mind was a little fuzzy as the booze started to kick in, and he hadn't even realised how close her head was to his own until he was looking into her eyes. Before either of them knew what was happening, their lips brushed together. Wine brought them together, and their addled brains and loosened inhibitions caused them to kiss.

It was soft and tender, experimental and brimming with tipsy passion, but was inevitably fleeting. No sooner had they kissed they pull away, and their sluggish, tipsy feeling very quickly sobered up once their minds comprehended what it is they just did. They paused for a moment, and as Amanda leant back she touched her lips, looking down at her hand. All Sully could think to do was avert his gaze and his face grew flushed; it wasn't his first kiss, but it didn't feel bad either.

"That..." Amanda began, not sure what to say, and Sully cleared his throat as he straightened in his seat. He wasn't about to take another glass of wine-- more than anything, his heart was pounding. His sister slowly sat up in her seat and leant forwards, taking her glass from the table. To Sully's surprise, she took a small sip of it and then set it back down again, as if she were steeling herself.

"We shouldn't have done that." She eventually said, and Sully hummed his approval, his nerves effectively shot. A tremor rushed through him as he tried to calm his nerves, and he pushed himself back onto the couch to get more comfortable, tucking one leg under the other to get comfy. Despite Amanda's words, however, her expression told a different story; she looked a little shaken, but most definitely flushed.

"Well, I didn't dislike it." Sully wasn't the type to keep his feelings to himself, and at his words, Amanda's eyes widened. She stared at him, mouth agape, before she cleared her throat and slowly leant back, pursing her muzzle. It was clear to Sully that she was deliberating it, and Amanda's mind was a whirlwind of thoughts, questions and feelings.

"...I didn't either." She admitted. Sully wasn't entirely surprised given her expression, but it was still a shock to hear her say those words. The two of them stared at each other for a moment before the raccoon shuffled a little closer, leaning forwards and turning towards her a little more.

"Do you want to do it again?" He asked, and she slowly nodded, leaning a little closer herself. He reached out his hands towards her and after a moment, she pressed a hand to his chest. He felt some degree of force and realised she was pushing him back, just a little, and he relented for a moment, watching her face.

"But first," She insisted quickly, brushing her gaze down. "We should make some ground rules, right?"

"What kind of rules do we need?" Sully quipped, causing her to scoff for a moment.

"Well, firstly...like, we should stop if we're uncomfortable, right?" She suggested, sounding apprehensive. "If it doesn't feel right, then we should just say stop and stop, no harm done."

"I mean, yeah, of course. Jesus, Amanda, what do you take me for?" Sully sounded almost offended, and as he pulled away she tugged him back in, curling her fingers around the front of his shirt.

"You know what I mean." She pursed her muzzle and he relented, aware that she was only being careful-- he did feel the same, even if he didn't like her tone at the time. He leant forwards once more and placed his hands on her forearms, and Amanda loosened her grip in response, dropping her hands. Wordlessly, Sully raised a hand and cupped her chin, forcing her to look up at him. His expression was hard to read, and frankly so was hers, but they didn't have to say anything. He drew his head forwards and, once again, they kissed. Their lips brushed, soft yet firm, and for a moment they lingered, experimenting with the feeling of it before Amanda pushed her head forwards and deepened the kiss.

Sully instinctively reached out to put his hands on her upper arms and pulled her towards him, leaning back as she pushed forwards. His back met with the arm of the couch as she leant into him and he soon felt her tongue brushing against his pursing muzzle, and in response he opened his mouth, willingly accepting her with a low groan. She clung to him and his body prickled with a mixture of desire and unease-- it felt wrong to do things with his twin sister, but it also felt strangely right. He couldn't be sure if it was the wine making him feel like this, or if he were simply more open than most. Amanda was having similar thoughts, though she was significantly more tipsy than him. In her mind, Sully had always been rather attractive, and kept himself in shape...there was no reason why she didn't think he was hot, at least on some level, even if she'd never really thought about it.

As they kissed, Amanda's hands roamed. They brushed from Sully's front and down his shirt, sneaking around to his sides. Sully did his best to hold her up, aware that she wasn't using either of her own hands to steady herself, and he soon felt her hands sneaking in under his shirt to brush with his grey fur. He giggled awkwardly against her lips and quietly gasped as he felt her tongue brush with his own, sending sparks of pleasure up his spine as her fingers raked through his fur and slid up his sides back towards his chest, feeling across his average muscles. Sully was neither muscularly defined nor flabby, sitting squarely within the regions of 'average' that made him conventionally attractive, but not a model. Sully greatly enjoyed the way she felt him up, but she didn't linger there for long. Her hands roamed across his chest and then snaked down towards his stomach, where Sully instinctively sucked in his stomach as they drifted even lower, plucking at the waistband of his boxers. Sully instinctively tensed when one of her hands brushed over the front of his underwear and felt what lay beneath.

There was a quiet moment where Amanda paused and pulled back from their kiss, not moving her hand nor exploring further. Sully was rigid under her touch, both physically and literally, and he winced briefly as his cock, hidden beneath his boxers, twitched and pulsed up against her digits. If that wasn't an indication of how interested he was in pursuing what they were doing, then what was? His anxiety, however, stemmed from Amanda's reaction...but thankfully, the black-furred feline smiled, and she raised her gaze to meet his.

"Do you want to go upstairs? The couch is a little uncomfortable." She asked quietly, and for a moment Sully didn't say anything, before he took her hand from his crotch and rose to his feet, pulling her along with him. Both of them were nervous, that much was obvious, and they quietly giggled as they made their way to the stairs and headed up towards the bedrooms above. Amanda thought that Sully might lead her to his own room, but to her surprise he passed his own bedroom door and headed further down the upper hallway, towards a room at the far end that both of them knew was their parent's room.

"Sull, we can't--" Amanda began, but Sully didn't hesitate to open the door to their parent's room, greeting them to a fairly well-kept sort of bedroom. Clothes lay draped across the back of a chair sitting opposite a vanity table, and the wardrobe was wide open, revealing an array of different clothes for both genders. The sight didn't really shock either of them, considering their parents had been getting ready to go out not that long ago, but Amanda felt awkward being in their room without them home, especially given what they intended to do. Sully, however, clearly had no sort of shame on that front.

"Better their bed than our cramped ones, right?" He argued, and she couldn't refute it-- she'd had sex with her ex-boyfriend on her own bed a few times, and the fact it was a single bed gave them very little room to be experimental. The feline squirmed on the spot, her tail swishing back and forth, and with a roll of his eyes the raccoon pulled her inside, leaving the door wide open as he slipped his hand around her waist and turned them, until she was facing away from the bed.

"Wait," She began as he lowered his head, causing the 18-year-old man to freeze. "We shouldn't mess up their sheets."

Sully paused, before he stepped to the side and grabbed his parent's blankets and duvet, throwing them towards the end of the bed so that only the bedsheets could be their cushioning, covered over the mattress topper.

"We'll wash the sheets." He insisted, and before she could argue he directed and pushed her back, causing her to flop onto the bed. He towered over her for a moment before climbing up onto the bed atop her, and she scooted back so that her feet could lift from the floor. He shifted and adjusted and Amanda instinctively spread her legs to accommodate him settling in between them, but the pair of them were both clothed; they weren't quite yet at the stage where they'd do that yet. Instead, Sully lowered his head down and drew her into another kiss, propping himself up with both hands, and she reached up to hook her arms around his neck-- she was a little nervous too, and also felt a bit weird about doing things with her twin brother, but she was also enjoying it; that made it easy for her to just sink into it and relish those pleasurable sensations that made her fur tingle and her tail curl and sway, brushing against her brother's ringed own.

Was it wrong to want to potentially have sex on their parent's bed? Of course, but did Sully care? Frankly, he did not; he kissed and squirmed atop her with a clear, unbridled passion, and he yearned to explore her and to sate his desire. His once nagging worries about fucking his sister, his twin no less, had all but been drowned out by his desire and lust, and that showed in his actions. Amanda could have never expected her brother to be so passionate, but she didn't hate this side of him; she always knew he was a man of action as opposed to words, and her plentiful kisses and brief huffs painted a particularly steamy picture, at least for her. With each fervent kiss, her loins tingled more and more, until it felt almost unbearable.

Eventually, Amanda loosened her arms from around her twin brother's neck and trailed her hands down his upper arms, sneaking them beneath his limbs and towards his sides. She hiked up his shirt as he parted his lips from hers, dipping his head to the side to roam against her cheek, and as his grey muzzle trailed down to her neck and kissed deeply against the crease between that and her shoulder, she groaned and raked her hands up his back, beneath his shirt. She didn't claw him fiercely, but she made a point of gently grazing the skin beneath his fur with her little pinprick claws, causing him to shudder from the sensation and hum into her neck, approving of the feeling.

"Mmh, that feels good." Amanda sounded jittery, perhaps even nervous, and her words made her twin brother chuckle against her neck. Slowly, Sully pulled back, withdrawing his mouth from her and staring down at her flushed face and body, before he leant up entirely. Her hands slid from his back and she looked at him with a bewildered expression for a moment, before her eyes widened as he grasped the hem of his shirt and pulled it over his head. 

"Figured it was about time to start taking our clothes off..." He muttered, looking down at her with a lidded gaze, and a grin crossed his features at her gawking expression. If the sight of his clearly tenting cock in his boxers wasn't arousing enough, getting to see his topless form was more of a delight-- Amanda had seen it many times before, but it was like she was looking at it in a whole new light. She reached out to trail a hand down his smooth, fuzzy stomach before she drifted all the way to his pelvis. She was about to touch with his cock again, and its idle twitching made it seem like it wanted her to, but she instead withdrew and brought her hands to herself instead, taking the hem of her own shirt in her hands and squirming it up and over her body. Sully's gaze openly took in the sight of her slender figure and ample breasts, housed within a simple yet effective grey bra. He leant forwards to see if he could unbuckle it, but Amanda raised a hand, causing him to lean back.

"We'll be here all night if you do it." She teased, tucking her hands underneath her body and wriggling on the bed as she loosened the hook behind her back. Sully knelt back and watched her for a few moments, placing his hands on her knees and stroking down her upper legs, until she eventually withdrew her hands from behind her and waggled her eyebrows, giggling when she snuck the straps over her shoulders and loosened the bra completely. Sully was quickly greeted to the sight of what he would have said are a pair of perfect breasts, with tender pink nipples and black fur all around. He didn't hesitate to reach out and grasp one in her hand, his palms pressed to the underside as his index finger and thumb singled out the nipples between them. Amanda reached out to stroke along his upper arms and sighed as he squeezed and groped her tits, clearly enjoying his touch. She didn't want to openly compliment how good he was at foreplay, for there was no need; he could tell entirely from the way she squirmed and moaned.

Sully groped and cradled her breasts for a few more moments before he leaned forwards again, and Amanda let out a quiet gasp as the raccoon pressed his mouth down to her left tit, his muzzle pursed firmly over the nub of her nipple. She could feel his roaming tongue circle around her breast and suckle, his lips pursing and his teeth grazing her sensitive flesh as he played with one of her most sensitive erogenous zones. She reached up to run a hand through his hair and vocalised her approval with heated groans, which only encouraged him to continue further, his teeth occasionally teasing her nipple and making her already perky little nipple even firmer. Of course, Sully didn't stop there; after giving Amanda's left breast some dutiful attention, he removed his mouth and turned his gaze to her other tit, planting his muzzle on that one in turn. He suckled and gave that one as much attention and eager slathering and licking as the first, and his fervent, attentive suckling had Amanda shaking beneath him, brimming with pleasure.

"Wow, that's amazing," Amanda's voice quaked with her desire. "You're a natural."

"I pride myself in my talents." Sully quipped, and his cheesy words almost made Amanda giggle, but she stifled it. After a few more moments, Sully pulled back, sliding his hands from her chest back towards the bed so that he could bend over and kiss her again. 

It felt altogether more tantric than before, primarily because their bodies were now skin to skin, and he could feel the weight and heat of her breasts against his own chest. Her hands readily slid down his body and he could tell she was impatient, for she tugged at the waistband of his boxers, coaxing them down past his manly hips. Sully straightened his legs out and lifted himself forwards to help them descend, and his underwear briefly snagged on his cock before it dislodged from the tip. His member sprung to a 45-degree angle, and as he sunk himself down he was sure she could feel his mass, grazing and pressing down against her inner thigh. In the same way she had undressed him, he reached down to do the same, using one hand to prop himself up as the other tugged at one side of her pyjama pants, whilst she reached up to help with the other side. They shimmied and slipped down past her hands, and he glided his hand inwards, roaming between her legs and quickly finding she had underwear on as well...despite that, the dampness between her legs was obvious; she was irrevocably turned on by her twin brother...and in turn, so was he by her.

"Sorry," Amanda quickly apologised, aware his fingers were touching with the dampness of her panties. "I'm...really turned on."

"It's fucking hot." Sully murmured, and his hushed, husky tone made her shudder. Sully slowly moved, rolling to the side so that Amanda could take off her panties completely, and as she straightened her legs out to kick her pyjamas off he explored her, stroking up and down her side and pressing his hand in between her legs to graze the entrance of her pussy. She clearly enjoyed it and squirmed on the bedsheets from his touch, which gave Sully an idea. The raccoon slowly moved, sliding from the bed for just a moment so that he could get onto his knees between his twin sister's legs, and Amanda lifted her head to watch him with bated breath as he confidently brought his head closer towards her pussy, his hands moving to curl around her legs. After a matter of moments, his muzzle pressed to her lips, and the feline rolled her head back and mewled audibly as he stuck out his tongue, pressing it to her quivering folds.

A moan ripped through the raccoon's mouth as his cock stood to attention, twitching madly as his tongue dragged up and down her entrance. He relished the taste of her, and his instincts told him to probe and prod, to press and smear in circles, and each flick of his appendage and slather of his tongue had her squirming, moaning her approval whilst she tried to keep it quiet, aware that the walls of their suburban house were thin. Sully let out little lustful growls and hums as his tongue pressed and pushed, and he felt her hands atop his head, running through his hair and stroking behind his ears as she gently tugged him down against her entrance, wanting him to go deeper. He naturally obliged and squirmed his tongue against her folds, wriggling and writhing until that squeezing pussy loosened a little, allowing him inside. He explored only an inch or so of her, tasting her inner walls, and he could hear Amanda's breathing grow heavy with pleasure.

"Oh, Sully..." She mumbled, unable to say much more-- though Sully didn't need much more indication of how much she was enjoying it. With her fervent moans, however, came a certain degree of impatience, and as time went on his loins ached, begging to be touched, to be stimulated. After some time of his tongue dragging up and down and circling within her, Sully's cock was readily oozing the occasional droplet of pre-cum, and he felt like it would start to hurt if he left it any longer.

When Sully pulled back, he could tell from his sister's expression that she was ready, but he was going to ask her to make sure. Before he could, however, she reached up and tugged him down onto the bed, and he stumbled before falling atop her, planting his hands on either side of her shoulders. He looked down at her and she locked her legs around his waist, tugging him in and sheepishly grinning as she pressed her hands to his chest. The notable thing that Sully was paying attention to, however, was the mass of his cock lining up and pressing to her loins, grazing her inner thigh and trailing down to her entrance. He could feel her lifting her hips up against him, very clearly interested, and the sensation of being so close to penetration made Sully sigh, briefly closing his eyes.

"Mmh," Sully huffed briefly and pulled back for a moment, his breathing low and heavy. "Can I, um...put it in?"

"I've got an implant." She informed him, and he threw all caution to the wind, pressing himself against her and rolling back on top of her body. Amanda, in turn, twisted to lay on her back again, and the two twin siblings pressed down, fur to fur, as Sully's cock grazed and dragged against her entrance, wetting the underside of his cock with her arousal. He moved a hand down and propped himself up on an elbow as he grasped the base of his cock, angling it down until the tip met with her soft, inviting cunt. There was no going back now, for either of them. He briefly looked her in the eyes before he pushed, penetrating his twin sister for the first time.

The feline gasped, letting out a soft but delicate mewl as her insides immediately clamped down around his intrusion, and the raccoon closed his eyes and breathed a shaky sigh, relishing the sensation of those inner walls squeezing his cock. It had been a long time since Sully had fucked a girl, and though he wasn't necessarily pent-up, he felt as if he were on a hair-trigger. He sunk deeper and deeper, his average-sized cock sliding all the way in until his pelvis kissed with her own. She was well and truly turned on enough to provide very little resistance, and his member fit inside her so snugly, almost as if it were made for her. He settled there for a moment, enjoying the warm feeling of being inside her, before he slowly pulled back and started in on a slow rhythm.

Sully had watched a lot of porn in his day, but he knew to take everything within it with a grain of salt, and he followed his own instincts instead. He gyrated and rolled against her, not tugging back and thrusting like a wild animal, and in turn, she hooked her legs around him and clung to him for dear life, moaning quietly against his neck as he kissed her cheek and nuzzled down into her two-toned hair. He fit her like a glove, and she was both loose enough to easily slide back and forth inside whilst being tight enough to provide the friction he needed to pleasure himself. In turn, his gentle thrusts massaged her inner walls and had her gasping with pleasure, her eyes squeezed shut as she trembled with every other thrust. Her tail flicked back and forth and inevitably curled around his own as he thrust, with nothing but the laboured sounds of their taboo sex filling the air, occasionally intermingled with the lewd noises of his cock sliding back and forth.

"Oh fuck..." Sully murmured, and it didn't take long for Sully to start picking up speed, making his rhythm to Amanda's steadily increasing moans, which grew heavier and heavier over time. No matter how much he tried to match her enthusiasm, however, Sully knew he was going to finish first, and it took all his willpower to hold himself in as he thrust, his breathing low and heavy as he panted against her neck. He could feel her every clinging muscle, from the ones around his cock to the ones that gripped the rest of his body, that squeezed and clenched with her quaking pleasure, and that only served to turn him on even more. After some time, he knew he didn't have long left until he busted in her, but thankfully, Amanda was far more turned on than him.

"Right there, right...oh!" The feline suddenly tensed and her moans halted entirely, replaced by hefty gasps as her fingers dug against his back, threatening to prick his skin, and he felt her inner walls squeezing down against his gyrating cock, milking and gripping like a vice. She mumbled something incoherent in his ear, and he assumed, thankfully rightly, that she was close to her orgasm. He picked up speed ever so slightly but kept the same angle and motion, and that was enough for her. She abruptly relaxed against him and her insides clamped down even tighter than before, which in turn spurned Sully on. He could tell she was climaxing, and thought of it was made his stomach twist and his heart soar.

"Fuck, Amanda," Sully groaned, dipping her head down to her neck and growling against her fur. "I love you..."

A chill ran up Sully's spine and he halted, panic rushing through his body. Of course, he loved his sister, but both of them knew what he meant when he said that. He was scared of her reaction, and immediately regretted saying it, his cheeks burning with embarrassment at the thought. Before he could stammer any sort of explanation, however, Amanda suddenly tightened her arms and legs around him and pushed him to the right, forcing the raccoon to roll. He cried out as his vision blurred from the sudden movement, and before he knew what was happening he was on his back, and Amanda was straddling his body. She pressed her hands down to his chest and lifted herself up, exposing her ample breasts and lean figure, and Sully sucked in a deep breath at the sight...more than that, however, he was nervous. Her expression was hard to read, and he couldn't tell if she was upset by his words or not.

Amanda, however, didn't say anything about it. Instead, she adjusted her knees and slowly pushed down, taking more of his cock into her before she started to roll her hips, taking him by surprise. His cock naturally enjoyed such eager stimulation and the raccoon closed his eyes for a moment to relish the feeling of his member being milked, before he raised his hands up and clasped them to her hips, squeezing and holding onto her. He stretched his legs out, curling his toes as another moan ripped through him, and he heard Amanda quietly giggle, slowly picking up speed with her gyrations. She was a natural at riding, and Sully pushed thoughts of how she knew what to do to the back of his mind, focusing entirely on the sight of her rhythmically moving back, tight pussy and jiggling breasts. His fingers and thumb dug into the flesh of her hips and she curled her digits around his chest in turn, raking her claws across his fur.

"Amanda..." He gasped between the occasional pant, his eyes firmly closed. "Fuck, that feels amazing..."

"Yeah?" She seemed pleased with his approval and pushed her hips down with significantly more gusto, plunging his cock into her as deep as she could, causing him to instinctively lift his hips up against her. He was in heaven, and he didn't want it to end. All good things, however, eventually had a finale, and despite Sully's enjoyment, he knew he'd soon climax-- that was obvious from the tightening in his loins that had his hissing quietly from between his gritted teeth as the lewd, squelching sounds of his cock massaging inside her bounced around the room, intermingled with their heavy, panting huffs.

"Are you gonna cum?" She asked, lifting and lowering herself a little more, rolling her hips backwards with each plunge to easily stroking his cock even more, and Sully couldn't even utter a word-- all he could do was fervently nod, his moans growing heavier and heavier, and in turn she picked up the pace, hands planted to his chest. He dragged one of his own hands up towards her back as he planted his feet to the bed, tucking his legs up and thrusting up against her-- it seemed like the most natural next step, and putting some own effort into his thrusts seemed to turn him on even more. Amanda let out quiet gasps as he plunged upwards, putting in a bit more force than intended, but it was doing the job; as he thrust faster and faster, he suddenly plunged upwards as his pleasure grew, and he teetered over the metaphorical edge, passing the point of no return.

In a matter of seconds, he climaxed inside her, his cock vividly twitching and painting her inner walls with his thick, sticky, taboo load. He flopped his body down, each wild spurt shooting as deep as he could manage, and as he buried himself completely inside her she all but collapsed atop him, not even bothering to prop herself up. Sully panted heavily and angled his head down against her neck, nuzzling against her soft black fur, and Amanda turned her head to the side, sighing against his neck. For a while, they laid there and basked in the glow of their sex, before his once hazy mind became clearer, and he was met with the reality of what they'd done. Strangely, though, he didn't feel bad about it; in fact, the only guilt he harboured was that they'd done it on their parent's bed.

"...I love you too." Amanda mumbled quietly against his neck, and he instinctively slid his hands up to cuddle around her beck, burying his head into her hair and breathing in her scent. He remained inside her and they cuddled for longer than they should have, but neither of them wanted to move. They were enjoying each other's company far too much, but they couldn't hang around for long. After what only felt like a few minutes, but was, in fact, a good half an hour or so, there was a knocking at the front door, followed by someone pressing the buzzer.

"Fuck, the pizza." Sully groaned, and Amanda rolled off of him as he got to his feet, wandering naked to the window. Luckily, their parent's bedroom overlooked the street, and he drew back the curtains and opened the window so he could call down to the pizza guy below.

"Be right down, give me a minute!" He called down to him, before turning to Amanda. "Uh, I'll get dressed...do you wanna clean up and we'll have dinner?"

"Yeah, good idea." Amanda giggled, quickly getting to her feet and scooping up her clothes. For a moment, Sully stood there and enjoyed the sight of her, before he watched her half-waddle out the room to keep the cum inside, so she didn't make a mess.

Sully scooped up his boxers and quickly made his way down the stairs to answer the door, briefly having to get the money from the kitchen counter to pay the man before taking the pizza inside. He tried not to think about the peculiar expression the delivery guy gave him when he saw the 18-year-old almost completely naked, and instead focussed on the task at hand: setting up dinner, and swapping out their parent's sheets; the last thing either of them needed was their parents finding out they had hooked up. For now, he left the pizza sitting on the counter and went back upstairs, heading down the hall towards his parent's room-- he could hear the shower running from the bathroom as he passed it, confirming that Amanda was cleaning herself up.

First, he stripped the sheets from the bed, but left the blankets by the foot of it. He quickly bundled the sweaty sheets up and tossed them to the floor before retrieving another set from the top shelf of the wardrobe, where their parents typically kept bedding. He quickly, completely in the nude, put the new sheet back on, thankfully the same colour at the last. He dragged the blankets back up and then collected his shirt, just in time for Amanda to be done in the shower, right as he stepped out of the bedroom. They exchanged a glance and Sully openly looked her up and down, before he sidled past her and down the stairs. He took the pizza into the living room and made some space for it on the coffee table, and Amanda joined him not too long after.

"So..." Sully began as he finally flopped down onto the choice, having pulled his shorts on and taken a slice of pizza. "Should we talk about what happened?"

"Hmm...let's wait on it," Amanda suggested. "I'm still kind of vibing after we hooked up...I'd rather have my head clear before making any decisions."

"Wow, how mature of you," Sully quipped. "Maybe you'll actually move on from Tommy this time."

"Shut up!" Amanda slapped his leg and then leant up against him, taking a bite of her slice. "Put a movie on."

With a smirk, Sully picked something for them to watch and settled in for a lazy evening.

The rest of the night was uneventful. Neither Sully nor Amanda spoke of what happened, agreeing firmly on not discussing it until later. They sat, watched a couple of movies and laughed at how corny Christmas films were before their parents returned some 3 or 4 hours later from their office party. It was clear when they entered the house that the two of them were a little tipsy, and Sully and Amanda spent only a little bit of time with them before they went up to bed. They didn't even notice anything was amiss, and shortly thereafter the two 18-year-old twins went to bed as well, their minds filled with thoughts of what they had done.

Sully awoke the next morning to a knock on his bedroom door, and he grunted his response before the door swung open, revealing his sister. She was in a slightly different set of pyjamas than last time, though she was wearing the same top as before, emblazoned with that weird slogan. Sully rolled in his bed to face her and sat up, propping himself up on an elbow-- he could see that Amanda looked sheepish, and he was worried for the conversation they may have. She closed the door behind her as she entered the room, and quickly crossed the carpet towards him, taking a seat on his bed.

"So, um...I had some time to think," She began, getting straight into it. "You know, about what we did."

"Mmhm." Sully was a little groggy, but was 100% focused on the conversation.

"I don't...think..." Amanda began, as if she were placing her words carefully. "I don't regret it. I liked it. Quite a lot, actually...you're pretty good at it, you know."

"Good," Sully's ego inflated by several metres, and when she looked at him he continued. "I don't regret it either. It was fun...some of the best sex I've ever had, honestly."

"Cool," Amanda cleared her throat. "So since we have no regrets...I want to do it again sometime."

"...Amanda." Sully caught her attention and she turned her head to him, frowning with concern at Sully's intense gaze. She couldn't tell what he was thinking, but it was clear he had something important to say. After a few moments, Sully sat up and straightened up a little, scooting back until he was sitting up entirely. He tucked his knees up and Amanda was sure she caught a glimpse of his bare thigh, but she didn't say anything about it.

"I didn't just like it...I loved it. A lot," He awkwardly tried to meander through his words, but Sully was never the type to beat around the bush, so he just came out with it. "I want you to be my girlfriend."

"But..." She trailed off for a moment and pursed her muzzle. "You're my twin brother."

"I know," He said it was so much confidence that she was a little shaken by it. "But I still think we should give it a go. I like you a lot, and...you know, the sex was great."

"Okay..." Amanda brushed her hair back and dipped her gaze. "That's kind of heavy. I don't think if it's the right call...can we just take it slow for now, see where it goes?"

Sully was silent for a moment, before he nodded-- his expression made it seem like he wasn't mad or dejected, but Amanda could see the wistfulness in his eyes. She felt bad and leant forwards, kissing him on the forehead as some sort of apology. When she withdrew, he pulled her him and pressed his lips to hers, abruptly kissing her. She was glad the door was closed; it would have been hard to explain if one of their parents passed by the door.

"I'm willing to wait to figure out what you want." Sully insisted as their lips parted. "But...it doesn't mean we have to stop what we're doing, right?"

"No...I think we can manage to keep that part a secret for now." Amanda couldn't help but giggle and even Sully chuckled along with her. Though it was wrong, he felt compelled to pull her in again, and he did so, pressing his lips to hers once more. He could feel her leaning into it, but she did eventually pull back, likely too nervous to do anything too extreme whilst their parents were wandering around the house. He could understand that-- a hormonal young adult like himself was used to tip-toeing around sexual stuff.

Amanda lingered, and she looked as if she wanted to stay, but she instead rose to her feet, drawing away from him. Sully held to her as long as he was able before he relinquished his touch, and she headed over towards the door.

"Well..." She began. "I've got to call a friend, but after that...I'm not busy. Mom's going to go see a friend soon for lunch whilst Dad's at work...if that gives you any ideas."

A smirk crossed Sully's lips as he flung his bedsheets back, greeting his twin sister to the sight of him stark naked, with a clearly visible cock standing on end, the result of her reciprocating kisses. Amanda's gaze locked to his morning wood and she stood there, briefly flushed, before she headed out and shut the door behind her, leaving him to get dressed. She heard him laugh from the other side of the door and she pressed her back up against his door, sighing and looking up at the ceiling as her loins tingled with desire.

She tried not to think too much about getting caught-- she was mature and careful enough to keep things under wraps, and so was her brother. All she had to do was enjoy it.

After all, wasn't that the whole point?
