The Experiment - Final Week

The entire space of the opulent penthouse was filled with the primal symphony of Julie and Mark's shared ecstasy - a mix of breathless moans, sharp gasps, and whispered obscenities. Standard ambient sounds of the past few days.

"Yes… fuck me, Mark… more…," Julie whimpered into the plush sheets beneath her. Her voice was hoarse from hours of unrestrained pleasure, each syllable punctuated by his relentless thrusts. He took her from behind with an animalistic fervor, his strong hands gripping her hips tightly enough to leave almost permanent marks that would serve as reminders of their adulterous affair.

Julie had fully surrendered herself to him, shedding every last vestige of her former self like a snake shedding its skin. Their fling had escalated into uncharted territories of passion and intensity, pushing boundaries she never knew existed. She reveled in the depravity of it all; her inhibitions were long gone, replaced by an all-consuming desire for the constant orgasmic bliss she found herself drowning in.

Each dawn, Julie stirred from her slumber with a residual sense of guilt gnawing at her conscience. Yet, after indulging in a couple of stiff shots of vodka and puffing on a few cigarettes, that remorse was swiftly drowned by the rising tide of lust and yearning for more carnal pleasures. Every subsequent day saw the guilt shrink further into insignificance, as if being eroded by the relentless waves of desire.

Mark changed too - he discarded his professional facade as her counselor and instead devoted nearly all his time to playing the role of her lover. Their passionate affair left no corner of the penthouse untouched – they christened every spot with unrestrained sex; under the cascading water in the shower, amidst the bubbles in the hot tub, and even within the steamy confines of the room’s sauna.

As the days rolled by, Julie found herself succumbing more and more to Mark's control - his touch became her addiction; his voice, her arousal; and his dominance, her craving. She knew their love affair couldn’t last like this indefinitely, but for now, all that mattered was the euphoria she discovered in Mark's arms.

Sunlight trickled through the penthouse windows, splashing a cozy light on the plush bed where Julie lounged, her body still buzzing from their wild romp last night. Mark's arm was slung casually over her hip, while he swiped through some store pages on his phone.

"Julie," Mark murmured, "I know you're not sleeping, babe. I have a surprise for you today."

"Really? What is it?" she asked, curiosity fully waking her up.

"After breakfast I'm taking you shopping," he grinned, his eyes glittering with mischief.

As they strolled through the upscale shopping complex, Mark guided Julie towards stores offering the most revealing and sexy clothes. He encouraged her to choose cocktail dresses, bodycon styles, and mini dresses that would accentuate her newfound sexual confidence and daring persona.

In the confines of the dressing room, Julie eased her body into a provocative red mini dress. The fabric adhered to her like a second skin, tracing every contour and dip of her toned physique. The plunging neckline offered an enticing view of her generous cleavage, leaving little to be concealed. As she appraised her reflection in the mirror, a rush of exhilaration coursed through her veins at the unfolding metamorphosis within.

"Step out and let me see," Mark beckoned from just beyond the dressing room door, his voice laden with eager anticipation.

Emerging from behind the curtain, Julie was met with Mark's lustful gaze that hungrily swept over her form. "Oh babe... you look like a sex angel in this," he rasped, ensnaring her in his arms for a fervent kiss that ignited an inferno of desire within them both.

As their lips clashed in a heated dance, Mark guided Julie back into the seclusion of the dressing room, securing the lock behind them. His hands began an exploratory journey over her body - fingers grazing over taut nipples that strained against the thin barrier of the dress. A soft moan escaped Julie's lips as their kisses grew more ravenous.

"I want you... your mouth," Mark murmured huskily into her ear, his voice a low rumble that sent electric jolts down Julie's spine.

With all traces of restraint abandoned, she descended to her knees before him. Eagerly parting his trousers and freeing him from his constraints, she took him into her mouth without hesitation. Her tongue swirled around him in slow torturous circles before taking him deeper still.

Mark groaned above her as he threaded his fingers through her hair guiding himself further into the warm cavern of her mouth. Her senses were overwhelmed by him - taste, touch and scent - all blending in an intoxicating cocktail of illicit pleasure.

As she continued to tease and pleasure him, her mind was a whirlwind of lascivious thoughts. She reveled in the woman she had evolved into and the sinful delight she derived from Mark's touch. The guilt that once plagued her was now replaced with an intoxicating rush of liberation, making her crave for more of this forbidden ecstasy.

The following day, they ventured to the local sex shop, where Julie already bought her dildo before. Under Mark's guiding hand, she found herself drawn to the section of erotic lingerie. She felt her heart flutter as tried on the most erotic and provocative clothes they had to offer.

Next, they found themselves in the aisle of kinky toys. Mark's eyes lit up at a shiny butt plug and a double-sided dildo designed for simultaneous pussy and ass play. The idea alone made her blush hot and heavy. It was obvious that he had a thing for anal action, but she wasn't complaining. Hell, every time he took her from behind, it just amped up her pleasure and these new toys were potential tickets for even deeper exploration of uncharted paradise of pleasures.

Back at the penthouse, Julie dressed in the skimpiest outfit they bought. It basically left her naked, just a few straps that covered none of her intimate parts. And with her now signature dark makeup and bright red lipstick applied she transformed her appearance once more, making her look like the wanton whore she had become not only for him, but for herself as well. She loved how dirty she felt being like this.

"You look perfect, Julie," Mark praised her with adoration. "I already know this will be an amazing night."

First, they claimed her preferred territory - the expanse of warm carpet floor beneath the towering mirror. Julie was entranced by their mirrored selves; Mark's sculpted muscles straining with every savage plunge in her pussy and her own lewd reflection writhing in ecstasy as he dominated her from behind.

"It's time to play with your new toys, babe," Mark growled into her ear, his breath hot against her skin as he watched their reflection.

She responded with a moan, lost in the sight of their bodies moving together. But the pinnacle came when Mark reached for the lube and instead of his fingers, pressed an anal plug against her backdoor entrance.

"Ready for this?" He asked huskily, holding up the toy for her to see in the mirror.

Julie nodded eagerly, eyes wide and fixed on their reflection. Slowly, Mark worked the toy in inch by tantalizing inch until it finally slipped inside completely, securely lodged within her. She felt stretched to capacity and each thrust of his cock inside her sent shockwaves through her body that were almost too intense to bear.

But then Mark took it even further. His hands were firm and commanding as they lifted Julie, guiding her towards the window. He pressed her against the glass, cool surface making her shiver in anticipation with the city lights twinkling below them. The plug nestled deep within her ass added an extra layer of delicious discomfort.

"Stay still and enjoy the view," Mark mused, his voice a low growl in her ear as he positioned himself behind her and entered her dripping pussy in a single thrust.

Julie felt ****; exposed to anyone who might glance up from their evening stroll or gaze out from their own window across the way. But there was a thrill that came with it too - a rush of adrenaline that made her heart pound faster in her chest.

"No one can see us up here, probably," Mark reassured her, but his words held a hint of mischief as he continued. "But if they could... imagine what they'd see."

His words painted an image in Julie's mind: herself, a hot blonde woman, practically nude, pressed against the window like some erotic display.

"Oh God," she whimpered softly, feeling even dirtier and naughtier than before. Her cheeks flushed with arousal at this newfound exhibitionist streak.

Mark chuckled darkly behind her, "You like that idea don't you? You dirty girl."

With that he picked up the pace, his thrusts punctuated by their shared gasps and moans echoing around the room.

Mark's words had ignited something new within Julie. The possibility of being seen by a stranger, of being caught in the act, was both terrifying and thrilling.

As if sensing her thoughts, Mark grasped her hips tighter and increased his pace. His thrusts were now forceful and urgent, causing Julie to press harder against the window in pleasure.

"Fuck," she moaned, unable to control the loud noises escaping her lips. This was unlike anything she had ever done before - the danger and excitement of it all made every sensation ten times more intense.

Mark's fingers danced their way around Julie's waist, sketching out teasing circles on her throbbing clit. The sudden jolt of pleasure catapulted Julie into a realm of ecstasy. A gasp ripped through her, raw and primal, clawing its way past her lips as a wave of bliss wracked her body.

"Oh... oh God... Mark," she groaned loudly, the words tumbling from her lips in a breathless pant. Her voice was thick with arousal, an undeniable testament to the intoxicating vulnerability she found herself immersed in.

"I'm... I'm so fucking exposed... It feels... oh fuck it feels good..." She moaned long and low as waves of orgasmic pleasure crashed over her again and again.

But Mark was not done with her yet. He pulled out of Julie suddenly, leaving her feeling empty and wanting more. But before she had time to protest, he removed the anal plug and replaced it with the tip of his cock.

"Mark…," Julie exhaled, her fingers spread wide against the frosty window pane as he sheathed himself within her. She relished the sensation of him, throbbing and full, stretching her anus to her limits. Her eyes fluttered closed, and a shaky sigh escaped her lips, "your cock… it's so big… filling me completely…"

His rhythm was deliberate and measured at first, each forceful plunge sending ripples of ecstasy radiating throughout her body. "I knew you were going to love having me in your tight little ass." He whispered into the shell of her ear, his tone smoky and rough. "You're just that kind of girl who likes it intense and rough."

And soon, Mark's pace quickened and became more frenzied. He was lost in the moment, lost in the feeling of Julie's tightness around him. Their bodies moved together in perfect harmony, each one giving into their primal desires.

"Damn, Julie... your ass feels like heaven," Mark groaned, his voice hoarse with pleasure. His hands gripped Julie's hips tightly, pulling her back against him with each thrust.

Julie could feel herself approaching to the edge again with each passing moment. The combination of being exposed to potential onlookers and Mark's perfect movements was driving her wild.

"See those tiny creatures below, trapped in their boring lives? But we're here, soaring above them all, fucking like gods, doing whatever we want. Now tell me - don't you feel like a goddess right now? Isn't this what you truly want?" Mark's voice reverberated through the room as he pulled her hair back, a cocky and assertive tone that sent shivers down Julie's spine and ignited a fire in her core. His demeanor was always so primal when they were alone - raw, authoritative and absolutely intoxicating.

"Mark... oh God... Mark, this is so good... I fucking love being like this! I'm so turned on by all this, I'm gonna explode... I need you to fuck my ass now… and let everyone see it," Julie gasped out, her voice thick with desire. Her body trembled against his as she let out all of her lewdness. "Let them see what you’re doing to me… don't hold back!"

Her words hung in the air like a challenge as she pushed herself against the cold window pane. The city lights outside blurred into a hazy backdrop as Mark pressed her exposed body against the glass.

Each thrust of his hips sent jolts of pleasure through her body, pushing her closer to the edge of sweet release. The sensation of being taken so publicly while being shielded by their high-rise penthouse was intoxicating.

"I need you buried deep inside me till there's no separating us," she cried out, lost in an ocean of pleasure and debauchery. As he complied with her wicked demands, Julie knew there was no going back from this exhilarating descent into sinfulness.

She could hardly recognize herself anymore - this woman who writhed against the window with unabashed lust wasn't just a kinky adulteress, she was acting more like a wanton whore. And yet, she found herself embracing this new identity with open arms. Her desire for him was insatiable, an all-consuming fire that threatened to consume her whole. But instead of fearing it, Julie let it consume her, surrendering herself completely to the mind-blowing pleasure that Mark brought her.

"Mark! Mark, yes...oh... this is…divine! You’re gonna make me cum so hard!" Julie's voice echoed through the penthouse.

Each word she gasped was a raw growl or sharp gasp, intensifying her climax. "Ahh! Ahh! Fuck me, just like that!" Her pleas escalated in urgency, her articulate words transforming into blissful murmurs as tidal waves of ecstasy submerged her. Spasms of Mark’s cock in her ass were signaling he was approaching his own climax as well, and that helped her ascend to the pinnacle of pleasure from this newly discovered territory - the anal orgasm - causing her legs to falter beneath her as she released a primal howl, "OH MY FUCKING GOD! YES…"

As they teetered on the edge of climax, their bodies quaked in sync, racing together up the steep slope to ecstasy. Mark's release was a powerful surge of pleasure that roared through his bloodstream and exploded into her snug backdoor. His hot jizz filled her tight ass, each throb of his dick squirting out more of his creamy load as he roared behind her.

Julie's response was just as fierce, her body convulsing in such a gigantic orgasm that caused her to squirt a wet stream across the window in front of them - a true display of her uninhibited sexual release.

Their bodies collapsed to the carpet floor, still trembling from the aftershocks of their intense pleasure. Mark's arms wrapped around Julie as they both caught their breath, gazing at each other in amazement.

"Wow...that was...new," Julie finally managed to say, her voice hoarse and filled with satisfaction.

Mark chuckled while gasping, squeezing her tighter. "Yeah… for me too. I never had a girl that came so hard from anal."

They stayed like that for a few moments, basking in the afterglow of their passion and enjoying the view outside.

"Guess we've just invented a new form of window art!" Mark chuckled, pointing at the glass now decorated with Julie's climactic expression. "Look at your orgasmic Picasso!"

“Well, it’s not really a Mona Lisa… maybe we could call it a Moaning Lisa?” Julie shot back.

They both shared a deep, erotically charged laughter, their bodies still entwined in each others.

“You know… I’m not really a squirter, it happened just a couple of times before. But what really surprised me was that I came so hard while… you know, having it in the ass,” Julie wondered out loud. “I always thought it was just a myth or faked in porn that girls actually enjoyed anal. I had the idea that they merely endured it, at best. But after this…”

Mark propped himself up on one elbow, looking down at her flushed face, a smirk curling his sensual lips. “Anal sex, if done right, can be amazing for both partners. It's all about communication and trust... and a little bit of lube,” he winked. “But in your case today it was more than that. The idea of being exposed got you so worked up as well. You probably heard that the best orgasms begin in your head, right?”

Julie nodded as Mark continued.

"So, you see, it’s the excitement of being caught while doing something so naughty, combined with the taboo aspect of anal sex. Add to that the thrill of cheating and you’ve got a fiery cocktail that blasted you right to the stratosphere," Mark said, his voice dropping down an octave.

Julie blushed a bit but couldn't argue with his reasoning. It was true, all of it. Her inhibitions were completely gone and she was like a wild mare, with only Mark’s experienced hands and amazing cock being able to tame her.

"So... are you hooked yet?" Mark teased her with a mischievous glint in his eyes.

"You mean on the smoking or the sex?" Julie shot back, her eyes sparkling with mirth.

"Both!" he bellowed, his laughter echoing in the room as he playfully tickled her, causing her to shriek and scrunch up defensively. "You elusive little slut!" he chuckled, continuing his playful torment.

"I... I don't know Mark... it's been...” she bit her lower lip, unsure how to put her thoughts into words without sounding like a complete pervert, but decided that she owed him the truth. “It's been the best week of my life.”

"Really?" he prodded, stroking her inner thigh lazily. Julie shivered, both from his touch and the intense eye contact.

"Yes, I want more of this. More of you...", she admitted in a small voice. "I don't want to leave this bubble we created here, separate from the world… and reality. The way things were before we met... It seems so... grey now. Boring even." She ended with a shrug, unable to meet his gaze so he wouldn't see how much of herself she just revealed.

Mark propped himself up on one elbow again, looking at her intently for a long moment before he spoke, his voice low and filled with sincerity.

"I feel the same way Julie. This is our last week here and I have to admit the thought of letting you go back to your life is… well, troubling," he trailed off, reaching out to caress her cheek tenderly, tucking an errant strand of hair behind her ear. Julie met his eyes – frozen in place by the intensity she saw there. Her heart gave a jump-start inside her chest as realization dawned on her: he feels the same way too!

"Mark, I've said many things... in the heat of the moment. But trust me when I say this now - I don't want this to stop," she whispered, her eyes locked onto his in an unbreakable stare.

"Who says it has to?" He replied, his fingers tracing languid patterns on her sweat-slicked skin. "We can find a way to keep this going, even after the experiment is over."

Julie's heart swelled with hope. "Really? How?" she asked, her voice shakier than she'd like to admit.

"I... I can make it happen. I have a plan but it’s premature to say. Why don’t we discuss this by a dinner, what do you say? Say… tomorrow evening, would that work for you?”

"An evening meal out? Hmm, let me think," Julie started, her eyes shifting to the ceiling, pretending to be deep in thought. "I'd have to check my super busy calendar first. You know, between reading cheesy vampire novel for a third time and binge-watching reruns of The Golden Girls. I'm swamped." She gave him a playful wink before bursting into laughter. "Are you kidding me? Of course I'd love to go! Compared to staying here for yet another night, it’s like winning a lottery ticket!" Her voice was filled with genuine enthusiasm that was hard to miss, her excitement spilling over like champagne from a bottle shaken too much.

“Great! I have a nice place in mind… I think you’ll really like it. But let’s get a shower now and go to bed. I’m exhausted… and it’s all your fault,” Mark laughed and Julie joined him.

The flickering candlelight played a sensual game of hide and seek across Julie's attractive features. Her captivating blue eyes glowed with an inner fire that matched the flame dancing in front of her. As she lifted the slender cigarette to her full lips, she paused for a moment, letting the anticipation build before taking a long, luxurious drag. The smoke twirled and twisted around her lips before disappearing as she drew it deep into her lungs with an expression of pure satisfaction etched onto her face, remaining there as she exhaled an endless stream of delicious smoke.

Mark had truly gone above and beyond tonight; he'd pulled some strings and managed to secure them a table at one of the city's most upscale establishments. Not just any table though, they were nestled away in an exclusive section cordoned off from prying eyes. This secluded corner offered not only privacy but also an unparalleled level of service that catered to their every whim - including Julie's newfound vice. Despite being in a world where smoking was increasingly frowned upon, here they were allowed to indulge freely. The thrill of such decadence added another layer to Julie's already heightened senses making this evening even more unforgettable.

"Julie," Mark murmured, his gaze heavy with desire and admiration, "you are absolutely breathtaking tonight." His eyes roamed appreciatively over her figure, clad in a form-fitting red dress that showcased her sexual confidence.

A blush crept onto Julie's cheeks as she smiled coyly at him. "Thank you, Mark," she replied, exhaling another puff of smoke. She let it roll off her tongue slowly, savoring the taste. "This place is incredible. They are even allowing us to smoke inside. I understand now why some people objected so loudly when they introduced the ban… it’s pretty lame now that you have to scrounge outside to have a smoke."

Mark's gaze intensified as he reached across the table, capturing her hand in his. "You're right, Julie. It's unfair to deny someone of their pleasures just because others don't share them. Tonight, however," he drew out the words, running his fingers up and down her arm as he spoke, "is about us. About you." His eyes flickered over her body, sending shivers down her spine despite the warmth of the room. "You deserve all of this. You've come so far over the past few weeks, I am extremely proud of you."

The waiter chose that precise moment to interrupt their intimate moment, arriving with their meals; Julie smiled politely at him before turning back to Mark once they were alone again.

"Thank you, Mark. But without your guidance things would’ve been different."

He grinned devilishly and leaned in close enough that only she could hear him speak. "I think we both know what 'guidance' I'm referring to," he winked lasciviously before crushing out his cigarette in the ashtray.

Julie felt herself blushing from head to toe as she speared her food with a shaking fork, trying to focus on anything other than their passionate trysts together amidst all this opulence. The thought alone was enough to leave her breathless; how could she possibly return to her ordinary life after this?

As they savored their lavish meal, Mark treated Julie with nothing but respect and tenderness - a stark contrast to the dominant role he assumed back in their hotel suite. This duality was intoxicating; it added an extra layer of thrill to their relationship which Julie found herself relishing in.

"Julie," Mark began after a while, his tone taking on a more serious note than before. He reached across the table to take her hand gently in his own. "We need to talk about future. Our future."

Julie felt a flutter of anticipation at those words. The moment of truth was finally here.

"I've brought this up before," he began, his fingers lightly tracing the outline of her hand in his own. His touch was soft, almost tentative, as if he was afraid she might pull away.

"And I stand by my words. I believe you should consider leaving, uhm, your old life behind," he continued, each word carefully chosen and delivered with an intensity that held her captive. There was a vulnerability in his gaze that she hadn't seen before - it made him seem more human and less like the dominant figure he usually portrayed.

"Be with me instead," he proposed gently, the words hanging in the air between them like a delicate promise. His thumb started to trace slow circles on the back of her hand as if trying to soothe her worries away.

"I can offer you a life beyond your wildest fantasies," Mark murmured, his voice a seductive whisper as he leaned in closer. "A world draped in opulence - designer wear, worthy of adorning your divine body, culinary delights by the cooks we would hire, travels around the world... A life brimming with thrills and indulgence." His gaze dropped to her lips for a second before meeting her eyes again. "And of course," he added casually, the corner of his mouth lifting in a suggestive smirk, "a limitless playground of passion and desire to explore without restraint.""

His words sent a thrill coursing through her veins. Her heart pounded in her chest as she considered the idea - not just for a fleeting moment, but seriously. The selfish side of her, the side that craved pleasure and decadence above all else, was growing stronger by the day, overpowering remaining sense of duty to her family and obligations.

"Mark," Julie began, her voice a mere breath in the quiet room. She paused, biting her lip as she gathered her thoughts. "I... I'd want that so much." Her words hung in the air between them, heavy with unspoken desires and fears.

"There is a "but" part coming now, right?" Mark asked, his eyes searching hers for clues.

"Well yes, but I really mean what I said," she gestured vaguely around them, "us... what we have here. It's like a dream come true." She took a deep breath, steadying herself before continuing. "But ... I don't know how to make it happen. How do we take this... this thrilling fantasy we're playing out and turn it into something real?"

Mark was silent for a moment as he considered her words. He reached out, taking her hand in his own again and giving it a reassuring squeeze. "We'll figure it out together," he said finally. "For starters, we can start anew somewhere else... far away from your old life."

Julie's mind whirled at his words, images of a life filled with Mark - a life brimming with passion and excitement - flashing through her mind. It was such a stark contrast to the monotony of her past reality that it felt almost unreal.

"But what about your job... and my children?" she asked after a moment of silence had passed between them.

"We'll work something out," he promised, his gaze never leaving hers. His words were like sweet poison to Julie; they made everything seem so simple when she knew that reality was far more complicated than that.

A small voice inside her head warned against getting carried away by these fantasies. It whispered quietly but persistently about the potential pitfalls of their plan – would Mark truly accept her children? Would he be willing to take on the role of a step-father? And even if he did agree to it, could he truly excel in that role? How would Lily and Tim fit in a life he's suggesting?

With each question that surfaced in her mind, the dreamlike vision of their future seemed increasingly complex, casting a shadow over the intoxicating fantasy they were weaving.

As she prepared herself to point out her reservations, his phone interrupted them. He excused himself and walked away from the table to take the call. Julie couldn't hear what was being said, but his gestures indicated it must be something significant.

When Mark returned to the table, he put on a smile and tried to act as if everything was normal. However, Julie couldn't help but notice a slight shift in his demeanor – he seemed agitated by something.

"Is everything okay, Mark?" she asked, concern furrowing her brow.

"Oh, of course. Just reality catching up with us," he reassured her, though his eyes betrayed a hint of unease. "Listen, why don't we just enjoy our dinner and each other's company? We still have some time to figure everything out."

Their conversation never touched the main topic and despite his efforts to bring back the pleasant atmosphere, the remainder of their dinner was marred with a bit tension, a constant reminder of the phone call that had disrupted the perfect evening. Julie couldn't help but wonder how long they could live in this fantasy before reality caught up to them. She knew that she would soon have to make a decision, one that would probably shape her future forever. Doubts and fears clouded her mind, making her question if she was truly capable of making the right choice.

After Mark dropped her off in front the hotel, Julie found herself standing alone in the lavish penthouse for the first time in days. The quiet hum of the city below seemed to magnify her solitude, and she suddenly became aware how accustomed she became of this grandeur, as if it were her home. But it wasn’t her home and in just a few days she’ll be faced with that inevitable fact.

She wandered over to the floor-to-ceiling window, the one that still had remains of her juices crusted over it. The maid missed it, unsurprisingly. Julie gazed at the glittering skyline as she lit a cigarette, the flame from her lighter casting an eerie glow on her face.

"Fuck," she thought, inhaling deeply, "how did I get here?"

The past month had been a whirlwind of self-discovery and debauchery. As the smoke billowed from her lips, she reflected on her transformation – from a doting wife and mother to an insatiable sex-crazed nympho. It all began with smoking; with each drag she took the walls she had built to protect herself, and her family, bit by bit weakened until they utterly collapsed in the last week. The moment she began enjoying smoking was the moment she betrayed her old self and a new Julie began growing. Each inhale was not just feeding an addiction but connecting her to this newfound freedom, making her feel more attuned with this untamed side of herself that loved living life on the edge.

Then there was Mark. He had opened a door to a world of intense desire and insatiable lust for her. He skillfully played on her wants and needs, urging her to embrace her darkest cravings. She was enthralled by their intense sexual connection and relished in the sense of liberation and sexual energy it gave her. But she couldn't shake off the feeling that Mark was maybe a bit too invested in her, especially for just being a counselor in this study. Julie began to suspect that the first time she cheated on George - during their second photo shoot - Mark had masterminded the whole thing. He manipulated the situation and played his part so well that it felt like it was all her doing. But did she really have reason to resent him? Wasn't she just acting on her own desires after all? These desires had been there all along, and Mark simply helped her unleash them. And if she traced back her actions even further, was money really the sole reason for her joining this experiment? Or was she maybe looking for some real change in her life?

And yes, there was this smoking experiment. Something gnawed at the back of her mind – a nagging feeling that there was more to this than met the eye. She tried to shake it off, telling herself it was perhaps just residual guilt from betraying George. Yet as the days dwindled, that unnerving feeling that there were hidden motives behind this were growing stronger. For example, why wasn’t anyone else from the Institute meeting her? Where were all the doctors and scientist in white cloaks taking blood samples, measuring her blood pressure and who knows what else? That got her to wonder what will happen on her last day at the Institute and if she’s really going to see that money that was promised. What if this was all a scam? But to what end?

"Stop overthinking, Julie," she muttered under her breath, stubbing out her cigarette.

"Why stress about problems that might not even show up?" she pondered, her mind spinning with a thousand thoughts. "There are some real issues on the horizon that I'll have to deal with. But I've still got a few more days of pure pleasure to look forward to, and as Mark said - I'm gonna grab them with both hands!"

She poured herself a vodka on the rocks, its liquid fire soothing the turmoil in her chest. As she sipped, she stared at her reflection in the mirror – the woman staring back was incredibly sensual, confident, and unapologetically carnal. She couldn't help but feel a thrill of excitement at the sight, whispers of guilt fading silent.

“God, I love this new me! Who knew I'd peak in hotness at 32? All that exercise and yoga crap was a waste of time. Now, I just fuck for couple of hours a day and get four, five mind-blowing orgasms - and that beats any workout and meditation,” she mused as she observed a slight change in her figure. “My body is a bit softer but in all the right places. I look like a goddamn MILF. Still gonna hit the gym sometimes though, gotta keep this bod from turning into a chubster. But damn, these curves are making me feel so fuckable. George is such a lucky husband!”

The absurdity of her last thought hit her hard the second it passed her mind. Vodka got her so relaxed apparently, she forgot for a moment what she was doing to George was in fact very, very wrong. But for some reason she didn’t feel guilty at all, on the contrary, she blamed their bland sex life and used it as justification, “To be honest, what I have here with Mark is ten times hotter than our dead-ass fucking with George in missionary position for five minutes on a missionary Sunday, once a fucking month if we are lucky!”

With a flick of her lighter, the end of another cigarette ignited as she reclined back into the plush cushions of her penthouse couch. The smoke curled up into the air in an intricate dance, as if mirroring the whirlwind of thoughts swirling inside her mind. Her once ordinary life seemed so distant now, like a faded photograph from another era. The monotonous routine that once defined her existence was no longer appealing; it felt like a prison sentence she was unwilling to serve.

A wicked smile played on her lips as she took a deep drag from the cigarette, savoring the taste that had become so familiar over these weeks. She exhaled slowly, watching as the smoke dissipated into nothingness - much like how she wanted her past life to fade away.

"I can't go back," she murmured to herself, her voice barely audible over the hum of city sounds filtering through the open balcony doors. "I won't."

Her thoughts strayed to Mark and an undeniable heat spread through her body, pooling between her thighs at just the mere thought of him. His touch was intoxicating; his dominance over her body was something she craved with every fiber of her being. His cock had become an addiction - one she had no intention of quitting.

"One way or another," Julie declared defiantly into the silence of her penthouse suite, "I going to keep Mark in my life." Her tone held an edge of determination and selfish desire - this wasn't about love or companionship. It was about need and pleasure. It was about taking what she wanted without any regard for consequences or repercussions. She made a promise to herself that she won’t let any doubt or guilt ruin these last few days here and that she’ll get Mark to fuck her brains out as much as she wanted. She could hardly wait.
