It turned out that while Sasha thought Tony's suggestion of a trip to Vegas was a spur of the moment joke to try and make her feel better about what had happened, the superhero was being more than serious about a few days away from New York.

Tony had gone home later that Friday evening and Sasha had been crudely awoken by the blaring of her intercom on Saturday morning. She answered it with hazy eyes that remained closed and a Stark Industries sweater pulled on backwards, still half asleep as she stumbled towards the front door.

Henry notified her from the lobby that Tony had arrived and he needed permission to let him up to her floor. Sasha perked up at the mention of his name, hoping her fiancée was going to surprise her with her favourite breakfast bagel and a fresh coffee.

And while he did turn up at her door with those two exact things, he also wasted no time in telling her to pack a suitcase because the private jet was leaving JFK in two hours.

Stressed was an understatement to Sasha, she didn't do spontaneity like Tony did, feeling much more comfortable having everything planned out in advance. Despite that initial surge of anxiety, however, excitement soon replaced the flutters in her chest as she threw in a random assortment of clothes into a suitcase and wolfed down her bagel within a matter of minutes.

Happy dropped the two of them off at JFK airport and while Sasha was used to flying business class whenever she had to take a flight, surpassing the usual terminal all together was an entirely different feeling than just skipping the economy queue.

The flight was a little under five hours though the journey felt like minutes to Sasha, feeling at home in the luxury leather seats of Tony's jet and being served ice cold vintage champagne in a glass that kept getting refilled by the stewardess.

Tony's mind had been plagued with the idea of dismissing the cabin crew for a while and introducing Sasha to the mile high club on their flight across the country, but as he sat opposite her and watched just how comfortable she looked gazing out of the window with a drink in her hand, he was perfectly content doing nothing but looking at her.

After a smooth journey, they landed safely in Las Vegas and headed straight for Caesar's Palace, Sasha sitting with her face almost pressed up against the car window as they drove through the city, amazed by a place she'd only ever seen photographs of before.

Unpacking took an hour or so and Tony happily sat and helped Sasha decide which bikini to wear before they headed to a private cabana by the pool, another bottle of champagne on ice sat waiting for them out of the glare of the fierce Nevada sun.

Seeing Sasha on vacation had taken Tony by surprise. He wasn't sure what he'd expected, but after only knowing his fiancée as a woman who worked like she needed it to breathe, he'd never really considered what it would be like to sit beside her on a sun lounger and sip piña coladas.

That being said, Tony thought Sasha looked at home in the golden sun, enjoying the way heat waves shimmered across her body as she lay with her eyes closed, tanning oil making it hard for him to control his thoughts as he kept stealing glances at her while she slept.

He loved seeing Sasha in different lights, taking pleasure in the small things like rubbing sunscreen on her shoulders and watching her read a book with sunglasses on, things he'd never seen the woman he loved do before. Tony was completely mesmerised by her, and the way she acknowledged his longing stares with small laughs and shakes of her head only made him fall deeper in love.

Four hours, lots of alcohol and a cold shower later, Tony found himself sat at the bar in the hotel with a Negroni in front of him, completely content inside without even a flicker of conflict or torment brewing inside his mind, a peaceful solace had consumed him that day.

Sasha's margarita was sat untouched next to his drink, not even being able to take a sip before she realised she'd left her engagement ring on the side of the vanity in the room after taking a shower. She'd rushed back upstairs to get it, leaving Tony by himself.

"Is this seat taken?"

Looking up from his drink, Tony's eyes crawled up the long legs of a woman with dark blonde hair and bright blue eyes, a dazzling smile and black lashes that fluttered with a masked innocence.

She was classically beautiful with high set cheekbones and naturally pouted lips stained red, a short black dress with a plunge neckline complemented her chest and her small waist, accentuating her curved perfectly as she rest one manicured hand on the back of the vacant barstool next to Tony.

He swallowed once, fixing his eyes onto hers before tilting his head slightly, clearing his throat before speaking.

"Yes," he said, "I'm afraid it is."

The girl shrugged with a timid smile, looking over her shoulders, "Really? I don't see anyone around. Are you sure I can't join you? Margaritas are my favourite."

An anxious panic began to burn through Tony's veins as he clenched his jaw, the weight on his conscience of what had happened the other evening still weighed heavy on his mind, his current situation only adding to the pressure of making things right again.

"Sure they are," he kissed his teeth, "But you can't sit here, sorry."

"Can't sit here?" The girl raised a brow and leant forward, placing a hand on Tony's thigh that forced his entire body to freeze, a tension wrapping around his heart as he felt himself hold in a breath, paralysed with fear that Sasha would appear at any moment, "How about we take this someplace else, hm? I'm staying in The Bellagio, it's not far, we'd have a lot of fun."

Tony took a moment to compose himself, forcing out a controlled breath before looking up and meeting the gaze of her baby blue eyes, a flirtatious and suggestive smirk tugging on her lips as her sickly sweet perfume began to linger in the air.

"I'm sure we would, but what would be more fun is watching my fiancée kick your ass all the way back to your hotel, and if you don't get your hand off me, honey, I might just join in and help her out in doing that."

The sparkle in the girl's eyes died immediately, an unimpressed purse of her lips made Tony's heart only continue to beat faster as her hand stayed on his thigh, feeling as though it was burning through his jeans.

"Fiancée? Are you lying to me, Tony Stark?"

The way she said his name made his skin crawl and a disgustingly anxious sensation continued to pulse through his body as he fought off the urge to push her away from him despite how badly he wished he could.

Tony was rarely nervous but with the weight of his relationship possibly hanging in the balance because of a woman who desperately sought out a version of a man who died the day he met Sasha Coulson pressing down on his chest, he struggled to find the right words to say.

"Sweetheart, I said get off, did you not understand me?"

The blonde's eyes lit up with mischief as she crept her hand further up his thigh, the low lighting in the bar hiding her actions from the view of anyone around them, though Tony was sure his rage would've been obvious to a blind man.

"Why don't you make me, hm?"

As Tony felt her hand rest at the top of his thigh, any nerves dispersed and were replaced with seething anger, a rush that returned all confidence back into his bones and flicked a switch that made him narrow his eyes and clench his jaw as he looked at her.

"Get your goddamn hands off me before I break 'em, hear me? And if you don't-"

"I'll break them."

Both Tony and the blonde were stunned into a wide-eyed silence as Sasha's voice sliced through a thick tension, immediately making the woman remove her hand from his thigh and take a small step back, not reserving herself from condescendingly dragging her eyes painfully slowly across Sasha's body with a repulsed expression on her face.

"Sorry," the woman flashed an obnoxiously fake smile in Sasha's direction, "He's just too good to resist."

Sasha gave her an equally patronising smile in return, grabbing her margarita from the bar with her left hand and raising the glass to her mouth to take a sip, flashing the engagement ring in her face as she did so.

"Well you better find a way," she said as she licked salt from the rim of her glass, "Or I'll break this glass over your head. Have a good night."

With defeat scrawled across her face, the girl took one last glance at Sasha before turning on her heels and walking away, leaving Tony sat shaking in anticipation at what was about to happen, desperately racking his brains for an explanation to what had just happened and why the woman's hand had been on his thigh.

Sasha threw the the margarita down her neck in one go, placing the glass down on the bar with a sigh as she elegantly raised a finger to draw and salt from her lips, licking it clean before finally turning to look at Tony.

His eyes were wide and the panic was painfully evident, a soul-consuming worry had weaved itself into his mind and as he sat looking at Sasha with a million and one words struggling on his lips, his thoughts were silenced for a split second when he let his eyes fall across her body properly, loosing all sense of reality as he fell victim to her beauty.

A black leather mini skirt cut off mid-thigh, leaving her legs bare all the way down to her ankles where the thin straps of Yves Saint Laurent high heels decorated her tanned skin, a simple silk halter neck blouse flashed her collarbones and left room for her necklace to catch the light, a bold red lip and dark eyeliner made him feel increasingly intimidated by her power, unable to focus on any single thought for more than a second.

"I'm so sorry, she just-"

"What? Why are you apologising?"

Tony's face fell and the dread was taken over by confusion, furrowing his brows and shaking his head, "W-why do you think? You walk back in here and see some girl with her hands all over me and you're cool with it? If I saw some guy with his hands on you I'd have snapped his neck without giving it a second thought."

Sasha withheld the urge to smile at his admission of jealous, keeping her lips in a straight line as she looked at him, one hand resting on the bar as she stood beside him.

"I heard everything," she said, rolling her eyes once, "I came back in here and saw what was going on and stood behind that guy over there to watch. I heard everything you said and I was just going to leave it alone, but then she started to move her hands and I thought I was going to throw up so I had to come over here."

Tony let out a sigh of relief, placing a hand on his chest as he did so and letting a breathless smile fall across his lips, almost laughing to himself as the sanity returned to his body.

"I'm sorry I didn't do anything sooner, I didn't want to touch her and make a scene or anything."

Sasha just shook her head, "I get it, don't worry. I liked how much you backed me to kick her ass, though."

Tony chuckled, grabbing Sasha's hands and pulling him between his legs, moving his grasp to fall on her waist as she looked down at him with a smile that made his heart skip a beat.

"You can kick anyone's ass," he said with a smirk, "My girl's number one, always. Don't need anybody else."

Sasha's heart had admittedly dropped to the pit of her stomach when she walked back into the bar and saw Tony with the other woman, though as she forced herself to hang back and watch the scene unfold, she couldn't help but feel herself grow hot under the collar at the way Tony talked about her, stern in the calmest way with ice behind his cold eyes and frost in the words he spoke to her.

Intrusive thoughts had occupied her mind since the Stark Industries event the night before, unable to stop herself from worrying about the past and what decisions Tony might make in the future, but her doubt began to fizzle away as she watched her fiancée turn down a woman who looked like she could've easily walked on a runway.

"Excuse me," Sasha grabbed the bartender's attention with a smile, "Could you send up a bottle of champagne on ice to the penthouse please? You can leave it by the door, thank you."

"What are you doing? I thought we were going out to dinner, you not feeling well or something?"

Sasha turned back to look at Tony who's eyes were glazed in concern. With a fire in her chest she let her hands trail down the lapels of his blazer before lacing her fingers loosely through his own, tugging him to his feet.

"I'm fine," Sasha said, glancing over her shoulder and catch the eye of the blonde who was still staring with clearly no shame, "Just the way you handled that really turned me on, that's all."

Tony swallowed hard as he looked down at Sasha, desperate to kiss her as she licked her red lips, her head slightly tilted and eyes sleek.

"Yeah?" He said quietly, squeezing her hand inside his own as he too felt the stare of the other woman burning into him, "I didn't have you down as the jealous type, Coulson."

Tony's playful words riled Sasha up more, almost short for breath with only sexual tension to blame, "I don't like to share. You're mine, Mr Stark."

Within sixty seconds, Tony had pulled Sasha out of the hotel bar by her hand, watching with a proud smile as she spared no time in glaring at the blonde upon their exit.

They stepped into the elevator with another couple which forced them to keep their hands to themselves, unable to make eye contact with one another because of the pure adrenaline rushing through their bodies, their minds unable to imagine of anything other than what was about to happen once the door to their hotel room was closed.

Tony let Sasha lead him down the hall to their penthouse suite, lost for words but plagued by thoughts as his eyes carved along her legs and hips, almost losing his mind when she turned to look over her shoulder with a teasing smile.

Sasha began to walk away once they stepped foot into their suite, only Tony made quick work of slamming the door closed and grabbing her wrist, pulling her back into him and finally smashing his lips onto hers, moaning loudly at relief he felt of being able to kiss her at last.

Sasha tangled her fingers in his dark hair, growing hotter by the second as Tony's hands raced across her body, lifting her off her feet as she wrapped her legs around his waist, dragging her lips down across his jaw as he carried her into their bedroom, throwing her down onto the bed before shrugging off his blazer and tossing it onto the ground.

Tony paused for a moment, taking a second to look out of the huge floor to ceiling windows that looked out onto the wonders of Las Vegas before looking back at Sasha. Her legs were crossed at the ankles as she lay on the bed, her dark hair sprawled out around her and her chest being the only part of her that was loving as it continued to rise and fall.

That was until she lifted up her left arm, her hand outstretched as she looked up at Tony with a timid smile, "Come here."

"Don't have to tell me twice, princess."

With his palms either side of her shoulders, Tony hovered over Sasha's body as he kissed her passionately, occasionally pressing his lips to the tender spot on her neck before suppressing her desperate whimpers with another long kiss.

Sasha's hands clawed through his hair before her fingers unbuttoned his shirt, aching to feel his skin against hers as he used one hand to pull off her blouse, revealing her bare chest beneath the silk.

Tony's fingers traced her inner thighs beneath her skirt, crawling up her skin and expecting to meet lace underwear, though the sensation against his fingertips didn't change.

"No panties?" Tony whispered darkly, sucking gently on her neck before pulling away and looking into her eyes.

"Not tonight." She replied, shaking her head with her teeth sunk into her bottom lip.

Tony groaned before pushing two fingers inside of her and latching his lips into her own, moaning against her as he felt her nails scratch at his skin while he worked her, so easily drawing her to her highest point.

Sasha's eyes fluttered closed at the pleasure, feeling weightless at the way Tony touched her, unable to stop herself any longer from unbuckling his belt and pushing his jeans down past his hips.

He quickly kicked off the rest of his clothes and pulled down Sasha's skirt, dropping onto one knee to take off her heels for her. She raised herself onto her elbows and looked down to the end of the bed, hazy eyes watching Tony pepper kissed on her ankles and up her calves, sighing in pleasure at his tongue tickling her skin as he worked his way up to her core.

She grabbed fistfuls of his hair as he dipped his tongue inside of her, moaning between breaths as Tony teased her sensitive skin, forcing her to arch her back in reaction to his fingertips brushing against her before sliding in alongside his tongue.

Sasha was close and Tony could sense it, feeling himself edging closer purely because of the way she tasted and how sweet his name sounded being moaned from her pretty red lips.

He forced himself to stop before she finished, not wasting another second before resuming his position with his palms by her shoulders before he slid inside of her, watching as her eyes rolled into the back of her head with an angelic sigh of pleasure.

Tony dipped down and met her lips, kissing her the same way he fucked her, slowly and passionately as he revelled in the way it felt to feel every inch of her brush against him with each deep stroke.

"You feel so good, fuck, Sasha."

Tony closed his eyes for a second as he began to fuck her faster, not being able to control himself any longer as her moans echoed loud around him and her nails scratched his shoulder blades.

He looked down at her with furrowed brows and parted lips, panting and feeling on the edge of heaven as he found the words he wanted to say with a clear mind in that moment, slowing his pace to rhythmic, deep strokes that caused her chest to rise with every hit.

"God, I love you," he whispered, brushing hair from her face as he met her gaze, "You're the only one for me, tell me you know that."

"Y-yes," Sasha managed to whispered, her legs shaking weakly as tears formed in her eyes at the way Tony continued to reach her perfect spot with each stroke, one hand behind his neck and the other resting on his chest.

"Tell me you know," he continued, breaking his words with soft kisses on her forehead, "You're all I want, you're all I've ever wanted. Fuck, tell me I'm all yours baby, tell me that."

Sasha wasn't sure she could even think clearly let alone speak as sweat from Tony's hair trickled onto her skin, his cologne mixing in with the sex that filled the air pulled her mind into a lust-fuelled haze, though one that was cleared by the pure love she felt as she connected as deeply as possible with Tony.

She placed a hand on his face, pulling him down so their foreheads rest against each others. Sasha gasped as Tony continued to make love to her slowly, feeling almost tortured with pleasure by him and how deep he'd reached inside of her, his low groans making the hairs on her neck stand up and her nails dig into his skin harder.

The way he was so devoted to her made Sasha love him more and witnessing him beg to hear her tell him that he belonged to her was everything and more she needed to hear to bring her close to her climax.

"You're mine," she whispered, looking into his brown eyes and feeling nothing but a soul that felt like home, "You're mine, Tony."

He kissed her hard, her words driving him insane as he felt himself finish inside of her, her legs wrapping around his waist and the sensation of her body unravelling beneath him in soft moans made him loose his head in the clouds, coming down a lifetime later and opening his eyes to see her.

"Always," Tony said, both of them desperately panting for breath with lovesick smiles on their lips, "This is forever."
