The Experiment - Day 24

Julie was still in a half sleep, her heart pounding as she tried to make sense of the tangled mess of dreams, memories and emotions that filled her hazy mind. Lying on her back atop rumpled sheets, she could still feel Mark's touch lingering on her body, the sensations from their wild sex last night echoing through her nerves like electricity. A heavy weight of guilt settled in the pit of her stomach, threatening to consume her.

"Fuck… I did it again," she mumbled, the word slipping past her lips in a pained hiss. She didn't want to remember, but the images were all too vivid: sucking greedily on Mark's cock, begging him to fuck her harder, screaming all the filthy things he demanded, letting herself be degraded and used like a cheap whore. At least he had already left, thank God, she thought.

But just as Julie mustered the strength to sit up, she noticed Mark sitting in an armchair across the room, engrossed in a book. Her eyes widened in surprise, only a whisper leaving her mouth, “Mark…”

He glanced up from his reading, a charming smile playing on his lips as he caught sight of her. "Good morning, beautiful," he said, his voice dripping with honeyed seduction. His gaze lingered on her naked form, taking in every curve and hollow with undisguised appreciation. “You were so lovely, I couldn’t bear to disturb your sleep.”

Julie's face flushed red, and she quickly pulled the sheets up to cover her body, overcome with embarrassment. "Shit… I- I can't believe I did all… that," she said, her voice cracking.

Mark set down his book and moved to join her on the edge of the bed. "Shh, it's alright," he soothed, gently stroking her hair. "You just let your desires guide you, nothing wrong with that. We all need to let off some steam sometimes. And besides... you were incredible." His eyes darkened with lust. "You have no idea how long I've wanted to see this side of you”.

Julie shivered as goosebumps spread across her skin. "But I'm married... it’s wrong…" she protested. She knew she had to stop this right now, end this twisted game they were playing before it spiraled any further out of control... yet part of her didn't see any reason to resist anymore, there just seemed to be nothing left to salvage. She was already so deep down the rabbit hole and after everything she had already done, she felt lost and detached. But that powerful sensation from previous night when she unshackled her inner slut and enjoyed every inch of Mark’s cock was… just gone, replaced by emptiness and sadness.

"Oh come on, you don’t have to **** yourself too much wit that… you did what you needed and it made you feel good. Hey, I know just the thing to put you in the mood," Mark spoke in an upbeat tone as he walked to the room bar. He poured some liquor and brought her a shot glass filled with amber liquid. "Take this. It's exactly what you need right now."

"Is this… tequila?" Julie raised an eyebrow skeptically, eyeing the drink warily. “Are you kidding me? I can’t drink something so strong on an empty stomach.” She'd never been one for ****, and although she lately drank much more than she usually did, this was way too much for her to handle.

"Trust me," Mark urged, his expression softening with understanding. "Why else do you think so many people start the day with some hard stuff? Cause it helps, simple."

Hesitation lingered for a moment longer before Julie reached out to take the shot glass from him. She eyed him suspiciously and asked, “what kind of psychologist are you, exactly?”

“A successful one,” Mark chuckled but continued with a serious tone. “You think anti-depressants some of my colleagues like to prescribe are any better for you than a drink once in a while?”

She pursed her lips in doubt, lifted the glass to her lips and downed its contents in one swift motion, the fiery liquid scorching a path down her throat and pooling warmly in her stomach.

“Ugh… gross,” Julie winced in disgust, scrunching her face up.

"Well, there’s always a trade-off," Mark smiled. “But I'd bet you already feel a bit better, am I right?

Julie paused, feeling the tequila work its magic, spreading warmth throughout her body and dulling the sharp edges of her guilt. "Maybe," she admitted quietly, her thoughts still a whirlwind of conflicting emotions.

"Told you," he replied, that predatory smile returning once more. "Look, I'll go grab us some breakfast. You just relax and gather your thoughts, okay?"

————————

As the warmth of the tequila continued to course through her veins, Julie felt an inexplicable sense of calm wash over her. Her guilt, so suffocating just moments ago, now seemed to dissipate like mist in the morning sun. She blinked, puzzled by this sudden transformation.

"Is it really that easy?" she wondered, a small frown creasing her brow. She had never been one to rely on **** for solace, yet the effects were undeniable. "This is wrong," she told herself firmly, shaking her head as if to dislodge the thought. "I can't let myself become dependent on **** as well."

Mark returned promptly, balancing a tray laden with steaming mugs of coffee and plates piled high with scrambled eggs and crispy bacon. The pleasant scent of breakfast, mixed with freshly brewed coffee, filled the room, stirring hunger she didn't even know was there.

"I thought you'd be famished," he said with a wink, placing the tray on a bed food tray. "Breakfast in bed for my kinky little princess. Here, good food is another way of lifting oneself up."

Julie shot him a glare from under her brow, a half-hearted protest forming on her lips, but hunger won out. She tucked into the food ravenously, surprised by her own appetite. Mark watched her eat, sipping his coffee and smirking occasionally as if he knew something she didn't.

Once she had finished, Julie leaned back against the headboard and sighed contentedly. "That was delicious. Thanks, Mark."

"You're welcome," he replied, setting his mug aside and crawling closer to her. His eyes bored into hers, heated and intense, sending a shiver down her spine that wasn't entirely unpleasant. "So, what now? Are you going to flip back to your old self again and go for another guilt trip? Or shall we skip that part?"

Julie hesitated, her heart pounding in her chest like a trapped bird. The few sips of tequila she had consumed - combined with Mark's steely gaze - had loosened her inhibitions enough to consider the unthinkable. "I don't know," she confessed at last. "I still have a family... and responsibilities..."

Mark shook his head with a mix of amusement and impatience. "That's bullshit, Julie, and you know it," he said bluntly. "You didn't seem so concerned about any of that last night, did you? Don't even try to deny it; I can see it in your eyes." His hand crept up her thigh under the blanket, dangerously close to where it shouldn't be, but she made no move to stop him. "You loved it... every second of it."

Julie blushed, her cheeks flushing a fiery red. Damn him for being right! She had enjoyed herself last night more than she cared to admit, but she couldn't face the truth yet.

Seeking for a distraction, Julie reached for the pack of cigarettes resting on the nightstand beside her, her fingers trembling slightly.

"I need a smoke," she gasped, her voice barely hiding her agitation.

"Of course you do. Enjoy yourself," Mark replied with a grin, his voice dripping with anticipation.

Julie took a cigarette from the pack and positioned it between her full lips, her blue eyes locked on Mark's as she sparked her lighter. The flame danced in front of her face, casting a glow over her features as she took a deep drag, inhaling the smoke into her lungs. She held her breath for a moment, savoring the soothing sensation that spread throughout her body.

As she exhaled slowly, a cloud of smoke enveloped them both. Mark's eyes never left hers, his expression one of pure adoration as he watched her indulge in her vice.

"God," Julie sighed, taking another drag. "I don't know why, but these really feel incredible, especially the first one in the morning." She paused, her brow furrowing in thought. "You know, it's funny. I never would have discovered how amazing smoking can feel, so in a way I'm actually grateful for being part of this experiment."

Mark leaned in closer, his voice a low growl in her ear. "I told you this was a voyage of self exploration. Cigarettes just paved the way for you to find there's a bad girl hiding deep down, yearning to break free. And I think you’re excited at what you found. I know I am." His hand caressed her thigh under the sheet once more, his touch setting off a series of shivers that ran down her spine.

Julie took another pull on her cigarette, the smoke curling seductively around them as Mark's fingers edged closer to her heated core. It felt good and with the calming effect from nicotine she moaned softly, the smoke wisping between her lips as she exhaled. "You are awfully confident for a psychologist who had sex with a married patient," she purred teasingly, lifting her hips slightly.

"Confident?" he countered with a devilish grin. "I'd say I'm just a man who knows what he wants and how to get it."

The raw truth in his words made Julie dizzy with desire; instead of recoiling she found herself craving more, but he kept just gently teasing and caressing her, his fingers never touching the most sensitive parts.

"As I said," he continued softly. "Sometimes we need to explore our darker desires in order to truly understand ourselves."

"You’re right," Julie murmured, her excitement growing as she took another drag. "I've always been so rigid, so controlled. But ever since I came here and started smoking... It's like a whole new world has opened up for me."

"Perhaps it was always there," Mark mused, his eyes tracing the curve of her neck as she tilted her head back to exhale. "You just needed something to help you unlock it."

"Maybe," she agreed, her voice barely audible over the sound of her own breathing. "I can't deny that this new me I discovered is quite… interesting." She took another drag, the smoke curling around her fingers as she held it out to Mark. "Do you want a smoke?”

Mark shook his head, his gaze never leaving hers. "No, not right now, thanks. I prefer to watch."

Julie chuckled softly, the sound tinged with a hint of embarrassment. "You make it sound so... erotic."

"Isn't it?" Mark countered, his voice low and seductive. "The way you exhale the smoke through your lips, the way your eyes flutter closed when you take a drag... It's like watching a expression of pure pleasure."

"God, Mark," Julie whispered, her cheeks flushing with heat. "When you put it like that, who wouldn't be turned on?"

"Exactly," he murmured, his fingers still gently caressing her outer lips, never directly touching her innermost parts. "So go ahead, indulge yourself in the pleasure you desire."

Julie took a deep breath, feeling the weight of his words settle in her chest. With each drag, she allowed herself to sink deeper into the embrace of her desires, the guilt that had plagued her earlier now a distant memory. Finally, that same sensation from the night before returned; she felt truly free again.

"I don’t know if I should hate you or thank you," she whispered, her eyes meeting Mark's once more. "But you're the one who revealed this dark and dangerous side of me."

"Well I merely helped. And I definitely didn't create this side of you, Julie," he said, his voice firm but reassuring. "I just gave you the push you needed to embrace it. You've always been this person, hiding beneath the surface."

"Then I guess I have you to thank for liberating me," she purred, her voice sultry and low, "I've been thinking about last night... how you made me feel." She glanced at him from beneath her lashes. "It was like nothing I've ever experienced before."

His eyes locked onto hers, dark and full of desire. "I could say the same, Julie," he replied, his voice smooth as silk. "There's something incredibly intoxicating about watching a woman like you let go of the inhibitions."

She smirked, blowing out another plume of smoke. "You mean a married woman?"

"More than that," he said, leaning beside her, his hand supporting his head. "A woman who has spent her entire life playing by the rules, only to discover how thrilling it can be to break them."

Julie felt a shiver run down her spine, her arousal building at his words. "If I didn't know better, I'd say you were trying to corrupt me, Mark."

"Would that be so terrible?" he asked, his gaze never leaving her face.

"Maybe not," she admitted, her voice barely above a whisper. "But what happens when this experiment is over? When we have to face reality again?"

"Who says we have to?" Mark countered, his expression unreadable. "Perhaps… this is just the beginning of a new chapter. For both of us."

"You really think so? Is that what… you’d want?" Julie inquired, unable to hide the longing in her voice.

"Who knows what the future might bring," he replied, lust in his voice more obvious. "But I’d be happy to show you all the things you've been missing, Julie. I want to be there with you, exploring every corner of your desires."

Julie's heart raced at the thought of it – of a life filled with pleasure and passion, no longer shackled by the constraints of her old life. It was way more appealing then returning back to her old life, slipping back into her role of a doting mother, loyal wife and successful career woman. Yes, she wanted more than that in her life but… could she really leave her family behind? Cheating on her husband was one awful thing, but the idea of abandoning her own children? The thought of it made her sick, despite of all the appeal of letting go.

Fortunately, the experiment would last for an entire week, giving her plenty of time to make a decision. And in that moment, all she was certain about, was a craving for that sensation of Mark's cock being buried deep inside of her.

"Well, then why don't you come here and do something about it?" she teased, beckoning him with her finger.

As she leaned in to kiss him, he pulled back abruptly. "Not yet," he said firmly. "Remember your promise, Julie? You agreed to do anything I wanted. Well, right now, I don't want just a cheating housewife. I want the full package - the seductive little temptress you were last night."

Julie's eyes ballooned with shock at his audacious request.

"Huh? You want me to doll myself up… for your pleasure?" Her voice trembled with a hint of anger and hurt.

He leaned in close, his breath hot against her ear. "That’s exactly what I meant, but it’s not only for me. I want your exterior to match the fire that burns within you."

Julie wanted to object but instead she swallowed her pride. It was true, last night she felt more in tune with her desires than she had in years. The excitement at the thought of unleashing her inner passion and becoming the seductress that Mark desired was getting to her.

"Alright then," she murmured, a wicked smile playing on her lips. "You asked for it."

She stood up and slipped into the bathroom, her heart pounding in her chest as she closed the door behind her. She leaned against the cold tiles for a moment, taking a deep breath to steady herself.

"Let’s do this," she whispered to herself, determination lighting up her eyes.

———————

Julie opened the bathroom door and stepped back into the bedroom. Mark's eyes widened as they drank in her appearance, his lust evident in the way he licked his lips and shifted in his seat.

She was a sight to behold, an embodiment of raw sex appeal. Her long blonde hair cascaded in relaxed waves over her naked shoulders, drawing attention to her face that was made up in a daring, almost confrontational style. Her eyes were like blue pools, encircled by a dense layer of black eyeshadow that gave them a wolfish gleam, while her plump lips, twisted into a naughty grin, were slathered with unabashedly red lipstick.

The skimpy wine-red bralette, teamed with the matching lingerie skirt and thigh-highs, painted a picture of pure lust. The high-heeled stilettos she threw into the mix only ramped up her naughty charm. But it was her daring choice to ditch her panties that really took things to another level; her naked pussy out in the open cranked up her primal sexiness and left Mark gobsmacked as he drank in this raunchy spectacle before him.

"God, Julie... You look fucking incredible," he breathed, his gaze raking over her body with undisguised desire.

"Thanks," she purred, strutting towards him with a sultry roll of her hips. "I figured I'd let our little slut out for another spin."

"Believe me, I'm not complaining," Mark replied, his eyes glued to her delicious body.

Julie could feel her own arousal building as she observed the effect she was having on him. It was so alluring – this sense of power and control over her own desires and the effect it had on him.

"Tell me, Mark," she whispered, leaning in close so that her lips brushed against his ear. "What do you want to do with your naughty vixen tonight?"

"Oh, I have so many things in mind right now, babe. But first, I want to watch you play with yourself," he growled, his voice thick with lust. "Show me the energy that’s hiding in you, let it blossom. I want to see you become what you really are, Julie."

A shudder of exhilaration electrified her as she absorbed his words, her body already quivering with anticipation. She had never felt so liberated, so unburdened – and all it took was indulging in her deepest, most forbidden cravings.

With a wicked twinkle in her azure eyes, Julie perched on the edge of the plush couch, putting herself on full display for him. She reveled in the intensity of his gaze, tracing every curve and crevice of her body. As she slid a hand down to the junction between her thighs, she let out an audacious gasp, feeling the damp evidence of her desire.

"Look at me," she commanded, her voice husky with need. Her fingers dipped into her wetness and she couldn't suppress the throaty moan that escaped from her lips. "Look how ready I am for you."

Slowly, she plunged two fingers deep within herself and began to pleasure herself. "You’re making me behave like a bad girl, Mark." She whimpered out his name in pleasure as she continued to move her fingers rhythmically inside herself.

"Fuck... Julie," Mark groaned, his voice rough with desire. "You're so wet…"

"God yes... and so damn horny," she moaned back, rocking against her own fingers. "I can’t wait for you to fill me up with that beautiful cock and make me yours again."

Julie smirked at the wanton creature she recognized in the mirror – this sexy vixen who craved cock with an intensity that bordered on obsession. In this moment, she didn’t care about old-fashioned morals and expectations; all that mattered was this delicious carnal hunger coursing through every fiber of her being.

“Why don’t you use that dildo of yours?” Mark suggested with a glint in his eyes and immediately afterwards bit his lip.

Julie smiled in agreement but then it hit her. How the fuck did he know about her dildo? Did she leave it out in the open before?

“How- what makes you think I have a dildo?” She asked carefully, trying to mask her suspicions with a seductive tone.

“Oh, I know a lot of things about you, Julie,” he replied with an air of confidence. Perhaps a little too much confidence, Julie observed. “I’m your psychologist, remember? It’s my job to pick up on these things. And I have a feeling a woman like you always has her best friend close by. Am I correct?”

Her cheeks flushed a deep hue of red under his knowing gaze. She didn’t really buy his reasoning, there was something telling her he found out about her secret toy in some way. But the rising tide of her arousal drowned out her suspicions. She was so turned on she just didn’t care about anything else. She stood up and took her dildo from the drawer.

She positioned herself in front of the mirror and imitated the way he had fucked her last night. Her breathing hitched, and her pussy clenched in anticipation.

“That’s it, baby,” Mark groaned, his cock hardening even more if that were even possible. “Show me how you like to get fucked.”

Julie moaned as she slid the dildo inside herself. God, it felt so good doing it in front of him! Her reflection stared back at her with lust-filled eyes, and she couldn’t believe how hot she was. Damn did she want more of this version of herself!

Her hand rhythmically guided the dildo in and out of her tight cunt, her eyes transfixed on the reflection of her slutty image. She moaned softly as Mark watched with lustful intensity, his hard cock straining against his pants. The squishy sound of dildo probing her drenched pussy echoed through the room. Her nipples hardened under her gaze, begging for attention until she finally freed one hand to rub them gently through her shirt. She bit down on her bottom lip in pleasure, tasting her own arousal on her tongue as she leaned closer to the mirror to get a better look at her image. The sight of herself overwhelmed her senses - lips parted in a lewd smile, cheeks flushed red with desire. Her eyes locked onto Julie in the mirror, and she felt like she was getting fucked by her own lewd reflection.

"Do you feel it, Julie?" Mark's voice was a sultry whisper as he wrapped his arms around her waist. "The freedom, the liberation that comes from shedding society's shackles? You are more than just a woman, my dear. You are an embodiment of feminine power and desire. Your body is a temple of sensuality, and I am but a humble worshipper at its altar."

He pressed himself closer to her, his lips grazing her neck as he continued to speak. "You are not bound by archaic limitations set millennia ago by some goat herders. No, you are capable of anything your heart desires. And I want to be the one to fulfill those desires, to unleash the full **** of your passion and pleasure."

"Fuck… yes," she moaned, her voice a husky whisper in the throes of passion. Each forceful thrust was punctuated with an utterance of pleasure, "Oh Mark, you’re right...this feeling of giving in… it's making me feel free as a bird..." She gasped for air, her words tumbling out in sensual rhythm. "I love this...I love being like this with you…”

Mark's grip on her hips tightened, his other hand sliding down to join hers at her breast, squeezing it roughly. "And I love this side of you, my naughty little slut," he growled in her ear. His words sent a shiver down her spine and she arched her back to meet his touch. "You were always meant for more than PTA meetings and family picnics, Julie. You were born to be worshipped and adored...a goddess of lust and debauchery."

Julie moaned louder now, her face a mask of ecstasy as she came closer to climax. Mark's words were like gasoline on the fire within her, stoking the flames of rebellion and desire that burned deep inside. She pushed against him while fucking herself with the dildo. Her body trembled as Mark slid his fingers lower, grazing her engorged clit. "Oh fuck!" Julie cried out, the two of them working together to bring her closer to the edge of orgasmic bliss.

The sensations crashed over her like waves on a rocky shore - intense and all-consuming. "I...I'm going to...!" she panted out between harsh breaths. "FUCK YES…AHH… So good…” Her screams filled the room.

“Oh baby, you’re always so hot when you cum,” Mark said in her ear between kisses on her cheek. “You’ve made me so turned on my dick literally hurts. Be my good little slut now and help me out here.”

With a blissful expression on her face Julie just smiled at his request. She needed no time to recover - she pushed him to the couch and unzipped his pants with haste. She lowered her head to his throbbing erection and her tongue flicked out tentatively, tasting the pre-cum that beaded on the tip. The musky flavor sent shivers of excitement through her, and she eagerly wrapped her lips around him.

"Fuck, Julie..." Mark groaned as she began to take him deeper, her mouth working in tandem with her hand. She could feel his cock pulsating against her tongue, and it only fueled her desire to please him more.

"Does your little slut suck you off good?" she asked, looking up at him with wickedly dark eyes. Her voice was husky, dripping with lust and confidence she never knew she possessed.

"Better than anyone else," Mark responded breathlessly, his hands tangling in her light hair, urging her to continue her sinful ministrations.

She took him into her mouth again, feeling a surge of pride as she heard his moans of pleasure. This power, ability to bring such a strong man to his knees with nothing but her lips and tongue. It was intoxicating.

"Enough, baby," Mark gasped after a few short minutes of exquisite torment. "I need to be inside you."

Julie released him from her mouth with a wet pop, a lascivious smile playing on her lips. She recalled a scene from a porn she watched and decided to mimic it herself. Mark was surely going to love it.

She crawled onto the bed, her legs spread wide, and lit a cigarette. The familiar rush of nicotine mingled with her arousal, heightening her senses and making her crave him even more.

"Fuck me, Mark," she moaned between drags, teasing her swollen clit with the other hand. "It’s time for you to fill your smoking slut with that delicious cock."

"Oh Julie...there's nothing I'd want more than that," he growled, positioning himself between her silky thighs and thrusting inside her with a single, powerful motion. The sensation of him filling her completely was almost overwhelming, and Julie closed her eyes in ecstasy.

“Mmm…yes… your cock is so much better than that plastic…”

She took a deep, satisfying drag off her cigarette, the warm smoke filling her lungs. Puckering her lips, she exhaled a thick, steady stream of smoke towards Mark, watching as it clouded his face and shadowed his intense gaze. The sight of her, laid bare beneath him, indulging in what she initially despised, was an intoxicating vision that he couldn't resist.

As the tendrils of smoke dissipated, he leaned in to claim her lips, tasting the smoky kiss she offered. Their tongues danced together as they both lost themselves in the heat of the moment.

"You're loving this, aren't you, Julie?" Mark gasped, breaking away from her lips to tease her. "I mean this whole experience, you just can’t get enough of it, huh?"

He let his words hang in the air as he thrust into her, eliciting a moan that vibrated through both of them.

Julie responded by taking another languid drag, swirling the smoke in her mouth before exhaling it in a sultry cloud towards him. Her eyes met his defiantly, her desire unabashed and raw.

"I can't deny it, Mark," she confessed in a husky whisper, "I'm addicted... to all of it. This penthouse, the smoking... and you. I don't want any of this to stop."

Mark grinned, his cock twitching in response to her confession. "Well, I'm glad to hear that," Mark taunted as he continued to piston in and out of her. "And the best part is that you can’t resist being fucked by another man over and over again."

Julie's cheeks flushed at his words, but her arousal only heightened. "I know," she panted out, "it's wrong... but it makes me so wet knowing I'm crossing a line I can never uncross."

Julie couldn't deny it – the thought of her infidelity only added fuel to the fire raging within her. She wanted more, needed more, and so she flipped their positions, straddling Mark and impaling herself on his length.

"Mmm… you’re so deep right now… tell me again, Mark," she begged, her hips grinding against his as she took deep drags on her cigarette. "Tell me what a dirty girl I am."

"Oh, you're more than just a dirty girly. You’re an insatiable, horny slut, Julie," Mark panted, gripping her hips and guiding her movements. "You're fucking addicted to this cock, and you won't ever be able to get enough."

As his words washed over her, Julie felt her orgasm building, a tidal wave of pleasure threatening to crash down upon her. She rode him harder, faster, **** to chase down the elusive high that awaited her. And when it finally came, a cataclysm of ecstasy shattered every last shred of doubt and guilt. He was right - she was addicted to this!

"FUCK!" she screamed, her body spasming as she clung to Mark, their sweat-slicked bodies pressed tightly together. In that moment, all that mattered was the pleasure they shared – her old life a distant memory, replaced by this new world of unbridled passion and desire.

Her gasps and moans echoed through the air as Mark flipped her onto all fours, her ample breasts swaying with each movement.

"Ready for more?" he growled, his fingers digging into her hips as he resumed his vigorous thrusts. The sensation of him filling her, stretching her, sent shivers down her spine.

She stubbed out the cigarette, preparing herself for another round. Her voice trembled with desire as she stammered, "Yes...but how are you able to hold out for so long without cumming?"

"I can hold back as long as I want to, Julie," Mark grunted, his breathing ragged. "I have full control over my own body… and I want to give you a proper fucking that only a real man can provide. You deserve it, babe."

That statement only spurred her on further, and she rocked back into him, taking every inch he had to offer. The heady mix of adrenaline, lust, and submission was intoxicating – a potent cocktail that had her begging for more. With each thrust, she felt herself slipping deeper into this depraved world that Mark had introduced her to, and part of her feared she'd never find her way out again. But as he started rubbing her ass with his finger while pounding her pussy mercilessly, Julie knew she wanted him to take her even deeper into the depths of depravity.

"Mmm… play with my ass, Mark… I like it," she moaned. "It’s so naughty…”

“You like that, huh? I think we can be even naughtier today,” Mark chuckled as he withdrew from her, went to the bathroom and promptly returned with a bottle of massage oil.

“Damn, these penthouses are really well stocked,” Mark mused as he poured the warm oil all over her supple buttocks, letting it trickle down and pool between her parted cheeks.

“Oh my… this oil… it’s nice…” gasped Julie, her heart racing with anticipation.

“Julie, I want you to suck on this while I play with your ass,” Mark said, pointing to his thick and rigid cock.

Her pussy ached as she turned her head around and looked at him with lust filled eyes. She knew what he wanted, so she took his cock in her mouth, her tongue swirling around the tip while he fingered her ass with care. The unusual sensation sent a shiver down her spine, and she moaned into his cock.

“That’s it, babe...” Mark moaned in pleasure. “Relax for me...mmm...”

As he began to penetrate her anally with his oiled-up finger, Julie moaned around his cock, the double sensation driving her wild. Her pussy clenched around nothingness, frustrated at being neglected as she indulged in this taboo act.

“Yeah...such a good slut...I knew you were made for this,” Mark purred before withdrawing from her mouth. He positioned behind her and much to her delight re-entered her pussy. He added a second finger to the anal play and slowly pushed them in her ass.

Julie whimpered, feeling stretched and full as he pounded her pussy steadily, his fingers delving deeper into her forbidden hole with each thrust.

“You like it, don’t you? You want it harder?” he groaned as he spanked her ass.

“Yes… God yes,” she moaned.

“Good girl,” Mark praised before picking up the pace, his cock and fingers moving in unison.

The sensations were overwhelming, and Julie was rapidly approaching another orgasm when Mark abruptly stopped.

“Oh no you don’t... not yet,” he said, smirking as he pulled out and removed his fingers.

“Please…it felt so good… I was getting close…” Julie wailed in desperation.

“I’ll get you there soon, babe, we’ll just make a slight change,” he said as she felt pressure against her ass again. But this time it was something thicker – his throbbing manhood.

“Ahh...Mark... you’re too big, I don’t think-” she gasped as the head of his cock breached her tight ring.

“Shhh..” he soothed, stroking her hair as he pushed inch by inch inside her unchartered hole. “You can take it...I know you can.”

Julie's heart was hammering in her chest as Mark began to push into her, the sensation of him slowly filling her up causing her to bite down on her lower lip. The initial sting of his intrusion felt like a hot flash, searing through her body and making her muscles tense. She held onto the sheets beneath them, white-knuckled and breathless.

"Talk to me, Julie," Mark murmured, his voice low and husky with desire. "Tell me what you're feeling."

She tried to form words, but they seemed stuck in her throat. The sensation was overwhelming; she had never felt so full before, so stretched out and taken. It was an intensity that was, in honesty, quite painful, but for some weird reason there were signs of pleasure in it s well - a sweet kind of agony that kept her curious.

Mark paused then, allowing Julie time to adjust to his size. His hand came up to stroke the side of her face gently. "Breathe," he calmly instructed in her ear.

Julie nodded slightly, inhaling deeply and letting it out slowly as she tried to relax around him. His patience was comforting; it gave her time to acclimate herself with this new experience.

Gradually the discomfort began fading away, replaced by an unique sense of fullness that was becoming rather exciting. She turned around, meeting Mark's gaze and there was something raw and **** in the way she looked at him.

"It feels...so fucking stretched," she managed finally, each word punctuated by a shaky exhale. Her fingers dug into the sheets beneath them as she added softly: "...and full."

"Relax for me, Julie," Mark murmured, his tone soothing yet charged with carnal magnetism. He began moving slowly again, giving Julie time to adjust to his size.

She moaned at the foreign sensation, a mix of discomfort and an inexplicable thrill. "Oh...God." Her voice was shaky, barely a whisper, yet dripping with anticipation.

"You're doing so well," he cooed, stroking her hip comfortingly. His slow thrusts became more confident as Julie relaxed, his cock sinking deeper into her tight ass.

"Jesus, Mark... it’s so intense, but… I’m getting used to it," Julie found herself groaning. This was a different kind of pleasure, raw and primal, the thrill of the taboo fueling her arousal.

Mark's thrusts became more deliberate, but he didn’t dare to push too far. "Tell me, do you want more?" he asked.

"Yes...I want more… but not too much," Julie pleaded, the words tumbling out between labored breaths. Her confession was met with Mark's approving grunt as he plunged even deeper into her, the depraved act heightening their shared pleasure.

"Look at you," Mark murmured, his tone thick with lust. "You've tossed aside that wholesome wife facade like yesterday's news and transformed into my ravenous little sex kitten. You're even spreading those tight cheeks for me to pound your virgin ass."

"I can’t help it," she whimpered, accepting the reality of his words. "I can’t… resist it… ahh, God… like you said, I am your slut...and I’m loving every bit of it."

From a tentative exploration their moves slowly morphed to a proper anal fucking. Mark's hips slapped against Julie's ass with a delicious urgency, his cock driving deeper and deeper into her forbidden depths.

"You love my cock even when it’s buried deep in your ass, do you?" he growled, his voice guttural with lust as he pounded into her. The conflict within Julie's mind had dissipated, replaced by the haze of lust and need.

"Yes... oh God, yes!" She gasped, her voice a throaty whisper that echoed off the sterile walls of the hotel suite. The words were torn from her lips as if she had no control over them, a raw and primal affirmation of the pleasure coursing through her body. Her moans were muffled by the plush pillow beneath her face, every whimper and cry absorbed into its soft fabric.

"This...this sensation...it's crazy," she gasped out, her voice barely a whisper as she tried to articulate the overwhelming torrent of feelings flooding her senses. It was something entirely new, a raw and primal experience that made her heart hammer in her chest and her breath hitch in her throat with every rhythmic surge of pleasure.

"I-I still can’t believe this is happening… you’re fucking my ass… and I love it… I fucking love this," she confessed again, the words tumbling from her lips in a rush of heated exhalation. Each syllable was punctuated by a sharp intake of breath, like an erotic punctuation mark underscoring the intensity of what she was feeling.

"It's like nothing I've ever felt before," Julie continued, struggling to put into words the sheer magnitude of the ecstasy coursing through her veins.

"And it's you...you're doing this to me," she murmured, acknowledging the source of this newfound ecstasy. A sense of surrender washed over Julie; surrender to these sensations, surrender to him - surrender to herself.

But what truly ignited the fire within Julie was not just the physical pleasure derived from this forbidden act. It was also the sheer wrongness of it all - offering up herself in such an intimate, **** manner to another man. This level of depravity was something she had never truly contemplated before, let alone acted upon.

Yet here she was, willingly abandoning herself to these sinful pleasures with Mark. And as his hands gripped her hips tighter and his pace quickened, Julie found herself reveling in this new-found sense of erotic liberation. Every gasp and moan that escaped from between her parted lips became an anthem to this dark desire that now consumed her completely.

"I could be doing this to you every day, babe," Mark groaned into her ear as he slowed down a bit and pulled her hair, turning her towards him. "Imagine a life like this, filled with luxury, booze, cigarettes, everything you want. You name it. Each day we could be fucking like this, discovering all the kinky stuff and depravities we both love. Wouldn’t you like that?"

Julie's blue eyes flared open and she looked up at him, colliding with Mark's gaze that was ablaze with carnal desire. In the depths of those fiery orbs, she saw a stark truth staring back at her. The old Julie, the reserved and virtuous family woman she once identified as, was gone. Vanished. Erased from existence. In its place stood an insatiable slut, a harlot who reveled in the delicious cocktail of sin and pleasure.

"Yes," she cried out, her voice a symphony of surrender echoing through the room. Her spine arched like a bowstring, tensed and taut as he plunged back into her inviting warmth. "I want it, Mark... I want all of it!"

A spark ignited in his darkened gaze, an inferno that mirrored triumph and conquest. He seized her lips in a savage kiss, his tongue delving deep within her mouth like an invader claiming new territory. His rhythm accelerated to match the frenzied beat of their hearts, pushing Julie precariously to the precipice of another earth-shattering climax.

"Then say it," he urged with a growl. "Tell me you're ready to embrace this new side of yourself completely!"

"I... I am," she panted, her voice breaking with each thrust he delivered to her burning ass. God, it felt so good, so wrong and sinful, matching his proposal perfectly. "I want this life... you’re offering."

There was no hesitation or reservation in her mind. This new Julie was an animal in heat, riding the waves of ecstasy as Mark relentlessly pounded into her tight ass.

"That's my good girl," he praised, his grip on her hips tightening, digging his nails into her skin. "Say it. Say you're mine!"

"I... I'm yours," she moaned, her voice hoarse with passion. "Only yours, Mark."

Those words sealed her fate, the final nail in the coffin of her old life. Julie felt him tense up behind her, the tell-tale signs of climax approaching.

"Your tight ass feels so good, babe. I’m so close," Mark grunted as he pounded into her relentlessly.

"Oh...God...yes...but please… make me cum! I wanna cum…" Julie begged, her voice hoarse with need.

Julie could feel the build-up of an orgasm, but this one was different, promising to be even more intense than the last. It was akin to standing on the precipice of a cliff, peering down into an abyss teeming with rapturous delight. Sensing her impending climax, Mark slid his hand around her waist and began to stroke her sensitive bud while quickening his pace.

"Let go for me babe... give yourself over to this sweet perversion," he urged in a low growl that sent shivers down Julie's spine. His words were like the final spark igniting the dynamite within Julie - she exploded gloriously, crying out as waves of orgasmic pleasure washed over her in relentless succession.

"Oh fuck... oh fuck Mark!" she screamed out passionately as she neared the peak of ecstasy. Her body twisted and writhed under him in rhythm with each pulsating wave of bliss. She could feel him stiffen and groan deeply as he too succumbed to his own climax.

"Oh God... I'm coming... I'm coming!" Julie cried out. The room was filled with their cries of ecstasy, their bodies entwined in a dance of passion that ended in an earth-shattering orgasm.

With one final earth-shattering thrust, Mark growled his release as he came deep within her tight hole; his seed spilling into her like a claiming brand mark on the very core of her being.

————————-

In the aftermath of their shared climax, Julie and Mark were entwined in a heated knot of spent desire. Their bodies, still glistening from sweat, were pressed together in an intimate tableau of sensual satisfaction.

Julie's heart pounded against her chest in syncopated rhythm with Mark's. A sense of profound bliss coursed through her veins, leaving her feeling utterly sated.

In Mark's arms, she had discovered a realm of such sexual freedom she had never dared to fantasize about, let alone explore. It was a world where the darkest fantasies she wasn’t even aware of were not merely tolerated but celebrated in all their raw intensity.

She'd totally given in to this fresh wave of freedom and for once, Julie felt truly alive - unfettered and free - basking in the afterglow. She lay there nestled against Mark's body, succumbing fully to her thrilling transformation.
