"Are you actually gonna do it?" the taller girl asked for what had to be the tenth time that night, perhaps even the twentieth. She was leaned forward over the back of an old leather couch on which her best friend had been awkwardly perched for more than an hour, the result being that their heads were so close her question could be posed as nothing more than a conspiratorial whisper.

"I dunno... I mean, I'd like to..." the friend replied, her eyes locked firmly on a handsome boy leaning against a wall on the opposite side of the crowded living room. While she may have had eyes for none but him there had to be something like a dozen other partygoers standing between the two teens and several times that many throughout the rest of the house. If she didn't know better the girl might have thought half their graduating class had shown up to celebrate Casey's birthday. Cassie's too, naturally, what with birthday parties being just one more item on the extensive list of things the twins had always shared. "You promise you wouldn't freak out, right?" the seated teen asked, pulling her eyes away from her longtime crush in order to turn and face his sister instead. "I don't want to make things awkward..."

To some people it might have seemed strange how alike the face waiting for her there was to the one she had just turned away from, what with the twins both sporting their mother's silvery-gray eyes and some nearly identical dimples, but then Amira had known each long enough for that phenomenon to be rendered routine. After all, the three of them, as well as her brother Naz, had all grown up in the same neighbourhood and spent more than a little of their collective childhoods together. From the hazily remembered days of their distant past in which they had raced on bicycles with training wheels to the more recent evening they had spent playing spin the bottle with their first stolen can of beer the quartet of friends had long been nigh on inseparable. It was that decade and a half of unbroken friendship which made the move Amira had been contemplating for the better part of a year seem every bit as enticing as it was nerve-wracking. Never had she known another boy who she trusted nearly enough to share her first time with, but neither had there ever been one whose lost friendship she would feel even half so keenly were things to go poorly.

Cassie knew well her best friend's dilemma, having first heard it confessed several months before and thus been granted more than enough time to come to grips with everything it would mean for them. "I mean, yeah, it'd definitely be a bit weird..." she whispered back, the girls' faces so close their noses were nearly brushing against one another. "But hey, I know how much you like him. And I'm pretty sure he'd be interested too so I don't wanna be the one who shoots you both down." Whatever reservations she might have had, the brunette just flashed Amira that same reassuring smile that always seemed to soothe her nerves. As critical as she considered her best friend's blessing, though, receiving it did little to dampen the teen's anxiety over the prospect of making a first move on Casey.

Swinging her head forward once more, Amira returned her gaze to the subject of their conversation. There was no question about it, a face wasn't all the twins had in common physically. Sure Casey was inch or two taller than his sister, but aside from that they shared the same slight build and wiry strength which came in no small part from many a year spent running with their school's cross country team. Back in the day Amira had been their teammate as well for a few seasons, but her body just hadn't really been built for competitive running and so she hadn't stuck with it as long long as the twins or her brother. Now, just as Cassie was finally beginning to grow into some truly feminine curves herself, her masculine twin had also started packing a bit more weight onto his sturdy frame. For him that bulk came in the way of more pronounced muscles in his arms and thighs, a development which only made him that much more dashing in the eyes of his secret admirer.

"So how long are you gonna just sit there and stare at him?" Cassie eventually whispered, the question and her hot breath against Amira's ear snapping the girl out of her admiring trance.

"Uh... forever?" the anxious teen mumbled, wincing and blushing in equal measure as she turned back towards her best friend. That almost certainly honest admission drew a healthy giggle from the grinning brunette, one so loud Amira was afraid it would draw more attention than she cared to endure at the moment. None of the nearby partygoers seemed to be particularly interested in the girls on the couch, however, not when there was no shortage of more interesting distractions to be found than the perfectly routine phenomenon of a teenage girl giggling.

Once her mirth had died down enough for her to fall quiet, Cassie adopted an almost pensive look, her lips pursed as she regarded Amira. The brunette's nervous friend watched warily as she slowly turned towards her brother, silently regarded him for a long moment, and then swung her head back again. Amira felt herself gulp as the elder twin's lips abruptly curled upwards into a familiar Cheshire grin which flashed two rows of near flawless ivory teeth.

"I think you need this more than me..." Cassie practically purred, one hand appearing from where it had lurked behind the couch in order to pass her best friend a flimsy plastic cup. Amira hesitantly accepted the drink, momentarily glancing downwards to check its contents. The amber-hued liquid within, doubtless one of the expensive whiskeys for which Cassie had inherited her father's taste, still reached at least halfway up the flimsy walls containing it. "Now, don't ever say I never did anything for you, Mir."

"Wha...?" the nervous teen started to ask, but by the time her eyes had risen from the depths of the cup back up to where her friend had been just a second before Cassie was already twirling away. Amira's eyes went wide as saucers as she watched the lithe brunette saunter off towards where her brother stood, gracefully weaving her way between the handful of drunken partygoers in her path despite her own partial intoxication. A few moments later and she was sidling up next to her brother, draping one arm around his shoulders as she leaned in to whisper in his ear.

For a second nothing seemed to happen, the handsome boy just carrying on his conversation with a pair of schoolmates as if his sister weren't even there. But then he came to a halt and leaned back so slightly the motion bordered on the imperceptible. All of a sudden the rest of the world seemed to freeze as Casey turned towards Amira's couch in what had to be slow motion. She had witnessed the smile which then blossomed on his lips more times than she could count, but all the same the sight of it was enough to make her feel as if a thousand butterflies which had been nesting inside her chest had suddenly taken off all at once in a whirling frenzy of wings. At first glance the expression was so similar to Cassie's smile that some might have called them interchangeable. To Amira, though, nothing could have been further from the truth. Where her best friend's smile had always had a way of calming her nerves the other twin's had for years never failed to make her heart skip a beat.

Another moment passed and suddenly Casey was casually strolling her way, sister and friends alike abandoned in his wake. For a split second Amira's wide eyes shifted over his shoulder to glance at Cassie instead but the lithe brunette just flashed her best friend a playful grin and fluttered her eyelashes before turning away to engage with the pair of confused boys her brother had left behind. Gulping once more, the anxious teen let her eyes flit back to her crush only to find he had already split the distance which separated them mere moments before. As he crossed the last few feet remaining between them, Amira swiftly lifted the cup she was still clutching in one trembling hand and hastily downed a mouthful of the whiskey inside. Cassie had most definitely been right.

There was a tremendous clatter to be heard as the door to Cassie's bedroom burst open, the shadowy stillness within instantly shattered by a flood of light from the hallway outside swiftly followed by a pair of teenagers every bit as drunk as they were horny. Ever since the room's full-time resident had none-too-gently nudged her twin into approaching Amira earlier in the evening, the two longtime friends had scarcely been apart for a moment. At first they had planted themselves next to one another on the same couch the nervous teen had occupied for most of the night, but even what limited privacy that spot held was lost to them when her brother Nazem finished his last round of beer pong and decided to drop by. Fortunately, no sooner had he done so than Cassie materialized as well, appearing as if from thin air to provide a distraction which allowed the potential couple to slip out a nearby door into the more secluded venue of the rear garden.

Once outside and seated on a stone bench between two rose bushes, the teens found themselves refreshingly free of unwelcome eavesdroppers and interlopers alike. Their new sanctuary was a touch on the chilly side, perhaps, but that itself had proven fortuitous in granting Casey an excuse to test the waters by wrapping one arm around Amira's shoulders. The budding paramour had been caught entirely off guard some half an hour earlier when his sister appeared at his side and strongly suggested it 'would be worth his while' to 'go and show Amira a bit of love' and it wasn't until the girl in question eagerly melted into his embrace that he was at last confident he wasn't being played. Right up until that moment he had maintained a strong suspicion that Cassie was playing one of her games.

While hardly the most prolific of pranksters, Casey's sister had long possessed a devilish streak which led her on occasion to enjoy a bit of fun at the expense of those close to her. Such occasions may have been rare, but the results were typically spectacular enough that those who had been targeted in the past quickly learned to keep a weather eye out for any sign of an encore. It was only natural, then, that Cassie's brother and favourite target suspect that she had gotten it in her mind to arrange some sort of embarrassing misunderstanding between himself and Amira for her own amusement. Such a scenario had certainly seemed more plausible at the time than one in which a girl he had known since they were each barely out of diapers had suddenly developed an interest in being more than friends.

Of course, over the years they had known one another Casey himself had hardly been above humouring the occasional daydream about his sultry friend. He was a hot-blooded teenage boy, though, so it was only natural that he fantasize about any number of pretty girls he would never get a chance to sleep with, let alone those he spent the most time with. Girls, on the other hand, were hardly interested in just anyone. As far as Casey had ever known, any guy one had known long enough to remember the days in which he had been afraid of cooties was supposed to be all but disqualified as a potential mate.

Given how swiftly and intimately Amira had responded to his tentative overtures, however, Casey had been forced to conclude that his sister was not, in fact, messing with them and that the gorgeous teen under his arm was interested in him after all. And rather keenly so, as best he could tell. While it most definitely came as a surprise, that revelation was hardly an unwelcome one. The intrigued teen couldn't say he had ever seriously contemplated the prospect of a relationship with Amira that was in any way romantic, but neither could he say the thought was unappealing. After all, they already knew the worst one another had to offer and none of it was enough to prevent them remaining fast friends. Love was more... complicated than that, perhaps, but one could never know whether it would come or not without making the attempt.

Whatever the odds of a serious relationship between the two teens actually working out were, there was no denying that the... physical side of things certainly gave Casey plenty of incentives to roll the dice. No longer the gangly little girl she had once been, the past few years had seen Amira blossom into quite the catch. Above her neck long waves of thick, dark hair framed a round, youthful face dominated by a pair of big hazel eyes and the impossibly long lashes which shielded them. Down below, the sultry teen had already grown into a woman's body with wide hips and the kind of delightful curves which made more than a few of her classmates turn to watch each time she walked by.

Given how eager he was to at last experience the near-mythical wonders of sex, how gorgeous the girl at his side was to behold, and how keen she seemed for it to happen, Casey's decision to suggest they head upstairs had been easily made in the end. However much he couched his invitation in code about 'finding someplace quieter to talk' they both knew what they were doing and, after returning inside to steady their respective nerves with one last pair of drinks, the nascent couple slipped away from the party proper looking to all the world like they were doing exactly what they were. Only once they reached the door to Casey's room was he reminded that he had already given a close friend the green light to use the bed within for a long-awaited rendezvous of his own. In the face of that chorus of groans and moans which could easily be heard through his door, the determined teen had promptly turned, led a fiercely blushing Amira down the hall, and instead barged through the next door he came across. So it was that the nascent couple unceremoniously stumbled into another bedroom instead, though one nearly as familiar to them.

"What are you... in here?" his breathless companion asked, her wide eyes sweeping across the distinctly feminine decorations of their new surroundings.

"Well, my bed's clearly busy and we're sure as hell not using mom and dad's," Casey answered as he swiftly stepped around Amira and closed the door behind her, an act which once more doused his sister's room in a blanket of shadows which spread out around the faint purple glow of her childhood nightlight.

"I don't know," Amira murmured, taking a few steps forward. "It feels so..." but Casey didn't wait for her to finish. With their privacy secured he turned back towards his longtime friend, swiftly crossed the distance between them, then reached out to wrap one hand around her midriff. When he pulled the girl back against his firm body her words trailed off into a contented purr and she reached up over her shoulder to clutch at one of his.

"She'll never know," Casey promised with all the confidence a little too much drink could provide. When he reached down to stroke his partner's thigh through her skirt he could feel a shudder rippling down her spine and a moment later she was nodding her agreement. From there he wasted no time in steering them both towards the nearby mattress.

Cassie's bed was meticulously arranged, each and every item on it from her lavender pillows and favourite pair of teddy bears to the monochrome quilt she had slept with for years allocated to its proper place and flawlessly aligned with the rest. That perfection stood little chance of surviving the arrival of her best friend and twin brother, however, and no sooner had they tumbled onto the mattress than its various compliments were rendered a chaotic tangle of cloth and padding.

Amira was the first to land, falling a little awkwardly onto her side but promptly rolling onwards until she came to rest face-up with her shoulder brushing against the neighbouring wall. The mattress beneath her was scarcely large enough for a pair of teenagers to lay upon side by side, however, so when Casey dove after her a moment later he chose to land atop his friend rather than beside her. No doubt thanks to the great many 'adult beverages' he had downed over the course of the evening, that feat proved more challenging to execute than the teen had expected and only by throwing up an arm to catch himself at the last second was he able to avoid crashing face-first into his newfound partner.

Perched as he suddenly found himself above Amira, Casey took a long, wobbly moment to drink in the sight of the shapely young woman whose hips he was straddling. Only were he blind could he have failed to notice the way her lacy black top had ridden up and left more than a little of the belly beneath exposed, one upon which the clearly-articulated canyons of his friend's younger, more active years had been smoothed out into a near-perfectly flat plane broken only by her navel. From there his eyes swept slowly up to the girl's ample bosom where his lustful gaze came to rest on a pair of perfectly matched mounds which strained helplessly against the tight confinement of their silky prison. By the time Casey at last pulled his eyes away from that glorious vista and finally raised them to Amira's face she was blushing as fiercely as he had ever seen before, a condition no doubt brought on by silently watching as her body was so thoroughly inspected. The rosy hue which tinted her neck and cheeks as a result, the way her lips parted slightly as if she were out of breath, the way she seemed to tremble beneath his gaze... it all served to make the sultry teen that much more alluring, a feat many a wistful classmate would scarcely have thought possible.

Now that his veil of ignorance had been lifted, Casey recognized any number of signs he had missed before, little hints of his longtime friend's interest which confirmed that it was no chance encounter in which they were engaged. Upon her and her brother's arrival earlier that afternoon to help the twins set everything up for their party he might not have paid Amira's outfit much mind, but it suddenly struck him that he recognized neither her dark red skirt nor the frilly black top which she wore above it. And given how much time all four friends spent together, he would surely have seen such an outfit before unless it were a particularly recent addition to her wardrobe. Had it been bought to catch her target's eye? To grant her the confidence necessary to at last make a move which might already have been put off a dozen times or more? It was enough to make one wonder, at the least.

In much the same vein, Casey was struck all of a sudden by the fact that, while Amira had long since proven herself an expert at the art of makeup, it was rare to see his friend's face done up so very intricately. Dark lipstick which made her mouth stand out against the honey-tan skin around it while harmonizing perfectly with the hazel eyes and long black lashes up above was a common enough sight as to safely be taken for granted, but the other splashes of colour around her eyes and cheeks which suddenly seemed as obvious as the rising sun displayed a level of skillful ornamentation he had previously witnessed on only a few special occasions. Clearly, he was not the only one for whom what was about to happen held a great deal of meaning.

Unable to resist his growing hunger any longer, and with scant few reasons to try, Casey wasted no more time before diving down to taste those dark lips which trembled so enticingly before him. The nascent couple's' first kiss which blossomed just a heartbeat later swiftly proved every bit as enthusiastic as it was fumbling. No sooner had their mouths collided than Amira's arms rose up to wrap themselves around her partner's neck in an attempt to pull him even closer, one which only served to set their clumsy noses, chins, and foreheads alike bouncing wildly off one another. Undeterred, the lovers' tongues were soon drawn into the fray as well, that pair of agile appendages each seemingly torn between clumsily trying to wrap themselves around the other and exploring the unfamiliar environs of a new mouth. All the while, Casey's hands drifted up and down his partner's sides in search of the right place to hold her, their meanderings never straying far from the girl's bountiful breasts even as their master lacked the confidence to let them draw too close.
