Nate was already awake when the sun started coming up. He was buzzing with anticipation and nerves.

Today was the day. The big Fourth of July party that would change everything.

He’d finally made it to the big leagues at StarPhire, the hottest fintech startup in the valley. And today his colleagues were invited to his home to show them he wasn’t just the compliance guy who did the lame shit. He had the perfect house, the perfect girlfriend, and he was all set to prove he belonged among the real players.

He slipped out of bed quietly, trying not to wake Nora, and padded downstairs to the kitchen. He made his coffee and pulled out his timeline one more time, grinning as he reviewed every detail. Food, pool games, his automated fireworks display. Every detail was locked down.

These weren’t just any coworkers either. The big players were coming. Marcus with his Wharton MBA confidence. Tyler who was turning down Goldman Sachs offers like they were spam emails. Jack, the technical genius who built the foundation of StarPhire. And Alex, the creative director whose campaigns regularly won awards. And he was going to be in their inner circle after this.

His knockout of a girlfriend Nora was the cherry on top, who would make them all jealous as hell.

He downed his coffee, then checked his timeline one more time. Nothing could be left to chance.

Not after that damned prank war.

The thought crept in despite his best efforts to keep it buried. He tried to push it away, focus on today, but the memory forced its way back. Watching Nora getting fucked by his best friends in his own bed, right in front of him. Hearing her beg for it.

“We were just acting,” she’d insisted any time he confronted her, those piercing green eyes penetrated his soul. “Where’s the trust after four years together?”

He’d tried to argue. “I heard you, Nora. I saw you, with my own eyes, right in front of me.”

“You think I would actually fuck your friends? It was just a performance to sell the prank, and it worked, we got you good!” Her voice gleeful as she reminisced about “winning” the prank war.

“We had to make it look convincing, right? God, Nate, you’re being so paranoid.”

Every time he brought up what he’d witnessed, she’d turn it around on him. Make him the problem. The jealous boyfriend. The one who couldn’t handle a harmless prank.

At some point it became easier to accept her story than to accept what his own eyes had told him. At least on the surface.

But he couldn’t face Dean and Finn again after what they’d done. He cut them out of his life completely, blocked their numbers, avoided the places they hung out. He couldn’t confront the truth, couldn’t let it disrupt his dream of perfect life.

But today was different. Today was the day he brought that dream to fruition.

He landed the dream job, now he just had to prove he belonged with the key players. Marcus with his Wharton MBA confidence. Tyler who was turning down Goldman Sachs offers. Jack, the legend who built the entire technical foundation that made StarPhire possible. And Alex, the creative director whose campaigns regularly won awards.

Nate was the compliance guy. He was brought in to do the boring paperwork while these guys changed the world. He set out to prove he was more than that. He wanted to be one of them.

He’d made a resolution not to drink today, stay vigilant, stay in control. Learn from his mistakes.

The back door opened behind him and Nora emerged, stretching like a cat in the morning sun. Even fresh from bed, hair in a messy tangle, she looked stunning. The months since April had been good to her. Her trainer had helped sculpt her body into something even more devastating than before, though Nate didn’t trust that smug asshole Brock for a second. Still, he could hardly deny the results Nora was getting, so he kept his mouth shut.

Her ass was noticeably rounder and more sculpted from months of squats and deadlifts. Thicker, more defined thighs that strained against whatever she wore. Those flawless double-D tits that still made his brain short-circuit, but now set against a narrow waist that emphasized her hard won curves into a perfect hourglass figure.

Nate had become pretty insatiable in the wake of her transformation, to the point of her annoyance. But she was giving him some leeway because she did enjoy the attention, and it clearly kept Nate happy instead of him asking too many questions about April Fools and the aftermath.

“You’re up early,” she said, her voice husky from sleep. “Planning your little party?”

“I just want everything to be perfect,” he said, trying to keep the edge out of his voice. “These guys are important.”

She rolled her eyes, strutting over to pour herself coffee. “They’re just a bunch of tech bros, Nate. Not the UN Security Council.”

She had no idea what was at stake here.

“I’m going to grab a shower,” Nora said, heading back upstairs. “What time are they coming over?”

“Around noon,” he called after her.

An hour later, she reappeared in a simple red, white, and blue bikini that showed off her amazing curves.

Nate felt that familiar mix of pride and anxiety watching her move around the kitchen.

“You look great, but maybe something a little less...” he started, then caught himself.

Nora’s eyes flashed dangerously. “A little less what?”

“I just meant, you know, it’s a work thing, so maybe something more conservative?”

“Maybe I should cover up because you don’t trust yourself or your coworkers to behave like adults?”

“It’s not that, it’s just...” He gestured helplessly. “This is important to me.”

She crossed her arms under her chest, pushing her tits up higher. “So I’m supposed to dress for your insecurity?”

“Come on, Nora. You know what I mean.”

“No, actually, I don’t. Explain it to me.”

He was digging himself deeper with every word. “Just ... maybe something that won’t distract everyone?”

“Right. Because my body is the problem.” Her voice was getting sharper.

“That’s not what I said.”

“It’s what you meant.”

“Think what you want I guess, but go change! I mean it! And before they get here!”

She turned to head upstairs. “Fine. I’ll change. Since you asked so nicely.”

Nate’s stomach dropped as he realized how he came across.

“Babe, wait, I didn’t mean...”

“You’re good,” she called back sweetly. “I’d hate to embarrass you.” She fluttered her eyelashes at him as she walked away.

At least she was going to change, but he knew he’d pissed her off.

When she returned a few minutes later, Nate’s eyes went wide.

“Holy shit.”

The new bikini was barely anything at all, tiny triangles connected by strings that seemed designed to disappear into her curves. The bottom rode up between her ass cheeks, showing off the sculpted butt that months of gym work had given her. The top barely contained her incredible tits, threatening to spill out with every movement, tied in front with a simple bow that looked like it could come undone with the slightest tug.

Nate noticed how that tiny triangle in front displayed her completely bald pussy against the tight fabric. He’d been asking her to get waxed for months, and she’d finally given in as she got more confident with her body. The thin material of the tiny bikini left nothing to the imagination, molded against her so tightly that it was obvious there wasn’t so much as a hair under it.

“You wanted me to change,” she said with a defiant smile. “So I changed.”

Nate’s mouth hung open but no words came out.

Before he could respond, the doorbell rang.

“Showtime,” Nora said, sauntering toward the back door. “Hope you’re ready for your big important party.”

Nate opened the front door to find his four coworkers standing there with coolers and grins. Marcus looked like he’d walked out of a magazine in his perfectly fitted polo. Tyler wore expensive casual wear that probably cost more than Nate’s mortgage payment. Jack looked deceptively relaxed but was clearly ripped under his shirt. And Alex had that laid back surfer vibe that made everything look easy.

“Nate! Ready for that firework show you’ve been promising us!” Marcus boomed, clasping him on the shoulder.

They made their way to the backyard, chatting about work and the market and StarPhire’s latest funding round. Normal guy talk. Nate started to relax, maybe this wouldn’t be so bad after all.

Then Nora stepped onto the deck.

The conversation came screeching to a halt. They suddenly found themselves staring at the most spectacular woman any of them had ever seen in person. Her toned, curvy body was showcased perfectly by the tiny bikini, every curve and line screaming sex appeal and confidence.

“Hey boys,” she said casually. “Welcome to our little Fourth of July celebration.”

Marcus recovered first. “You must be the famous Nora, you look absolutely stunning. Nate’s a lucky man.”

“Nice to meet you,” Tyler said, his eyes locked on her.

Jack just nodded, his mouth hanging open before he caught himself. “Hi, we’ve heard so much about you!”

Alex looked her up and down with obvious appreciation but kept his cool. “Great place you guys have here.”

Part of Nate felt proud watching them stare at his girlfriend, knowing she was his. But another part of him wanted to throw a towel over her and get her away from their hungry eyes.

But now it was time to show these guys what he was made of.

“Alright, it’s about time to fire up the grill,” he announced, walking over to his latest toy, the most expensive grill money could buy, loaded with every high-tech feature available.

He’d spent an hour yesterday testing every function, checking connections, making sure everything was perfect for today.

He pressed the ignition button. Nothing.

Pressed it again. Still nothing.

“Sometimes it takes a minute to warm up,” he said, trying to keep the confidence in his voice as he turned knobs and pressed buttons. The guys watched politely as ten minutes passed with no results. Everyone was getting hungry, watching him fumble with the controls.

“Tank might be empty,” Jack said finally, checking the obvious thing Nate should have thought of first.

“I just filled it!” Nate protested.

Jack stepped in, pushing Nate aside as he checked the tank, confirming Nate’s worst fear. “Valve was left slightly open. Looks like it leaked out.”

Jack shook his head with a half-joking smile. “Propane though? Really? Gas is just ... not real grilling, you know? Can’t get that flavor.”

He mentioned his barbecue competition wins, smoked brisket and ribs that took home trophies. “Low and slow, that’s the secret. Takes lots of patience and good ol’ fashioned know-how.”

Nate’s face went red. All that money on equipment, and Jack was politely schooling him.

“I’ll be right back,” Nate muttered, grabbing his keys. “Just need to swap out the tank.”

He had to drive to swap out the tank while everyone waited hungry, leaving Nora alone with his more successful, confident coworkers. The embarrassment burned in his chest the whole trip.

When he returned, he found Nora sitting casually on Jack’s lap while he regaled everyone with stories about his barbecue competition days. She was clearly comfortable getting cozy with Jack while Nate was gone. That paper thin bikini bottom was all that separated her smooth, waxed pussy from Jack’s thigh. The tiny triangle of fabric did almost nothing to hide the outline of her lips as she shifted against him.

“You need to let the meat get nice and relaxed before you start, really let the flavor penetrate deep,” Jack was saying, talking about injecting marinades.

Nora was hanging on every word, clearly enamored by his confidence more so than any real interest in barbecue techniques. “I do love a nice piece of meat,” she giggled, matching his energy.

Nate’s hands clenched into fists. He wanted to tell her to get off Jack’s lap but knew he couldn’t without seeming like a controlling lunatic.

The barbecue finally got started after Nate changed out the tank. He made a point of staying focused on the grill, keeping his distance from Jack. He didn’t need another lesson in front of everyone about how he was doing everything wrong.

“Need any help over there?” Jack called out, but Nate waved him off.

“I got it,” he spat more curtly than he intended.

Jack put his hands up. “Okay, you got it...”

But he was distracted watching Nora laugh and flirt with their guests. The smell of burning meat hit him too late.

“Shit shit shit,” he fumbled with the tongs.

He flipped the burgers quickly, but they were already charred black on one side. He tried to play it off, turning them and hoping no one would notice. At least the brats were salvageable.

Marcus wandered over to check on the progress. “Smells great, man.”

Nate forced a smile, even though the burgers looked like charcoal. “Just getting some good char on them.”

By the time he finished grilling, all the burgers he’d promised his guests were destroyed. Thankfully the brats turned out okay and Nora was back to sitting in her own chair, much to Nate’s relief.

Everyone grabbed plates and complimented the food politely, though nobody touched the burgers. “These look great,” Marcus said, grabbing a brat and loading it up with toppings.

But Nate watched as everyone avoided the burgers entirely. They were so obviously burnt that nobody even pretended to want one.

Nora was the one to point out the burgers were inedible. “Really?” she held one up. “I’ve been looking forward to a burger all day,” she said disappointedly as she glared at Nate.

Nora took one of the brats instead, skipping the bun. “My trainer has me on keto,” she explained when she got a weird look from Jack.

“Whatever you’re doing is working!” Jack said, nodding approvingly as he dug into his plate.

She noticed all the eyes on her as she wrapped her lips around the bratwurst, taking her time as she looked right at Jack. Her tongue darted out to catch some juice that dripped down her chin.

Nate watched with a growing knot in his stomach as she held eye contact with Jack, her mouth still on her sausage.

Nobody else said anything about the burnt hamburgers. He had a witty retort locked and loaded in case his coworkers brought it up, but nobody did, which made him feel worse somehow.

Nate’s face burned with embarrassment. Even the simple task of grilling lunch, he’d managed to screw up. At least the brats saved him from looking like a complete fraud.

“Beer, Nate?” Marcus offered, holding out a cold one.

Nate hesitated. He’d promised himself he wouldn’t drink today. Stay sharp, stay in control. But his nerves were already starting to fray, the grill issues, Jack’s polite schooling, watching Nora on his lap, and now burning the burgers... “Fuck it, why not,” he thought to himself.

“Yeah, sure,” he said, taking the bottle.

One beer became two. Two became three. The edge started to disappear, but so did his judgment.

As the afternoon progressed, things actually settled down nicely. Everyone seemed to be enjoying themselves, the food was good, and Nora was still sitting in her own chair.

The guys had started talking about the fireworks display, and Nate saw his chance to redeem himself. He talked up his professional-grade fireworks setup, explaining safety protocols in excessive detail. “I’ve got the whole thing mapped out, specific distances, safety zones, the works.”

The guys nodded politely, their “yeah, ok” responses should have been a warning.

Now that things were going well, Nate’s impaired judgment decided he needed to show off.

“Hey, you guys want to see some fireworks preview of tonight?” he announced, more than a little tipsy. His voice carried that false confidence that came from too many beers and desperate need for attention.

“No sense letting these things go to waste,” he continued, pulling out cheap bottle rockets that came free with every purchase when he got his fireworks. The irony wasn’t lost on anyone except Nate, who’d just lectured about proper protocols.

Tyler raised an eyebrow. “Isn’t it still daylight? Thought you said the big show was after dark.”

“These are just the warm-up act,” Nate grinned, his judgment completely clouded.

Instead of setting them up properly, he decided to hand-launch them to look cool.

He held the first rocket in his sweaty palm, flicking his lighter. The fuse caught immediately, burning faster than expected.

“Uh, Nate...” Alex started, but it was too late.

The rocket launched from his hand, flying erratically. Everyone watched as it careened sideways, nearly clipping Tyler’s ear before exploding against the fence.

“Dude, what the hell?” Tyler jumped back, spilling his beer.

Marcus shook his head. “Maybe we should wait for the big display you’ve been going on about?”

But Nate’s ego was fully engaged. “Relax, that was just a fluke. I know what I’m doing.”

He grabbed another rocket, trying to compensate for the first misfire. The guys stepped back, except for Nora who was lounging nearby, scrolling through her phone.

“Seriously, Nate, maybe we should...” Jack started.

“I got this,” Nate snapped, lighting the fuse.

But his overcompensation sent this one flying in the opposite direction. Straight toward Nora.

Time slowed as everyone watched the flaming projectile streak through the air. Nora looked up just in time to see it heading for her chest.

SHIT!” Nate screamed.

The hot rocket bounced off her tits and got caught in her bikini top. The fabric began to singe where the burning tube made contact.

Nora screamed and quickly yanked the tie of her bikini top just before the rocket popped.

Everything moved in slow motion. Nate watched in horror as his girlfriend flung her tiny bikini top through the air, revealing her perfect breasts to four sets of hungry eyes. Her nipples, already hard from adrenaline and the cool air, stood out prominently on her soft skin. The bikini top fluttered through the air, landing directly on Alex’s lap.

She was completely topless, standing in full view of Marcus, Tyler, Jack, and Alex, the people whose respect he was desperate to earn. Instead he’d handed them a full display of his woman’s magnificent breasts on a silver platter. It was all because of his stupidity, and it was obvious to everyone.

Nora’s tits looked more incredible than they’d been imagining all day. Full, firm, with perfect-sized pink nipples that begged to be licked. The afternoon sunlight highlighted every curve, making her look like something out of a magazine.

Her eyes, on the other hand, seared right through Nate like a high intensity laser.

“What the fuck is wrong with you!” Nora screamed incredulously. She picked up the bikini top directly off Alex’s crotch, making him squirm slightly. Her movements made her tits bounce and sway in his face as she bent down.

Everyone stared in shock at Nate’s reckless stupidity and at Nora’s spectacular exposed body.

“Babe, I’m so sorry, it ... it was an accident, I...” he stammered.

“An accident?” Nora cut him off, her tits jiggling with her angry gestures. “You nearly burned my tits off with your stupid little stunt!”

She examined the top, which was slightly singed but mostly intact.

“Ya know what? It’s fine,” she said firmly, tossing it aside. “I don’t need it. You ruined it anyway.”

The casual way she dismissed her top sent a spike of panic through Nate’s chest.

“I’ll grab you a top, Nora, I’m sorry.”

She looked around at the four guys. “Is this going to bother anyone?” She pushed her chest out and cupped her breasts from underneath like they were on offer.

They stammered various versions of “no” and “of course not.”

“See Nate? Don’t worry about it, we’re good.”

“No, you’re putting on a top!” he demanded.

“I said we’re good!” she responded with venomous nonchalance.

Alex stepped in. “It’s your body Nora. No one else can tell you what to do with it.”

Nora nodded approvingly. “Exactly. Thank you, Alex.”

Nate wanted to push back, but he was in no position to make demands. He’d just nearly burned his girlfriend with his carelessness.

The energy of the party changed completely with Nora’s tits out. The guys tried to act normal, but there was unmistakable sexual tension.

Nora seemed to relish the power she had over them, leaning into it. When she moved around, every eye followed her.

“Well,” Marcus said finally. “I guess the fireworks show started early.”

Everyone laughed, breaking some tension. Nate had shown himself to be exactly the opposite of what he was trying to present: careless, incompetent, insecure.

“Maybe you should put those away, don’t you think?” Jack suggested to Nate, gesturing toward the pack of fireworks still in his hand.

Nate looked down, realizing he was still holding fireworks like an idiot. “Yeah ... yeah, probably a good idea.”

With Nora topless and the immediate crisis past, the guys did their best to return to normal conversation. But normal was relative when you were trying to have a casual chat with a spectacular naked woman who kept leaning forward to show off her exposed tits.

Nora embraced her role as the center of attention, stretching her arms overhead to make her tits bounce, leaning forward when reaching for her drink to let them sway hypnotically.

“So anyway,” Marcus continued, trying to pick up his interrupted story, “we’re sitting in the conference room with the biggest client account in the city, and their CEO says...”

But he kept losing his train of thought as Nora positioned herself directly in his line of sight, her breasts swaying as she gave Marcus her full attention.

“Sorry, where was I?” Marcus laughed, running a hand through his hair.

“The CEO,” Tyler prompted.

“Right, the CEO. So he looks me dead in the eye and says, ‘If you can guarantee our ROI increases by thirty percent, we’ll sign.’ And I’m thinking, this is it. Make or break moment.”

Nora leaned forward, her tits practically spilling into her lap as she gave Marcus her full attention. “That’s incredible! How did you even think to approach them that way?”

She was clearly impressed, touching his arm as he talked. Marcus lit up under her attention, his natural charisma kicking into high gear.

“Well, it comes down to understanding what drives people,” Marcus explained, his confidence growing as Nora hung on every word. “I’d done my research, knew their pain points, their goals. Sometimes you gotta take the risk.”

“And did you close it?” Nora asked breathlessly.

“Seven figures,” Marcus grinned. “Biggest deal of my career.”

Nora’s eyes widened with admiration. “That’s amazing.”

Nate watched this exchange with growing unease. His girlfriend was practically fawning over Marcus’s success story.

Tyler cleared his throat. “Speaking of, don’t forget that my market predictions made it all possible”

Nora immediately shifted her attention to Tyler, who spoke with the quiet authority of someone who was always the smartest person in the room.

“I could see the pattern forming weeks before anyone else caught it,” Tyler explained, his precise, methodical delivery somehow making market analysis sound sexy. “All the indicators were there, commodity futures, currency fluctuations, behavioral patterns in the retail sector.”

“It all worked out I take it?” Nora asked, clearly turned on by his brilliance.

“To the tune of almost 50 million in assets,” Tyler confirmed with calculated precision. “Sometimes being right pays off.”

Nora was practically melting. “That’s so impressive.”

Tyler’s expensive glasses caught the light as he nodded. “Has to be that way in my position. One miscalculation can sink a firm, especially that early, it was make or break and you’ll notice we’re not broke,” he smirked.

“That’s about when we pulled Alex,” Tyler continued. “He’s a legend.”

“It takes a great team, I just make things look pretty,” Alex responded humbly, which just made him look even more confident. “I was still creative VP at FreshBite at the time, but they have a great team here, so I made the leap.”

Nora’s eyes lit up. “Wait, those FreshBite commercials, was that you? Those were everywhere! With the guy getting dumped over a delivery order, what was it?”

“Shawarma,” Alex grinned. “Well, we did a few, but that was the first one that really went viral.”

“Yes! That’s right! And all the shawarma breakup memes after!” Nora was practically vibrating with excitement, making her tits jiggle and bounce.

“I just did the artwork and animation, I’m not really a marketing genius, but the shawarma was my idea,” Alex said.

“That was genius! Everyone was sharing those.” Nora was touching his arm now, clearly turned on. “You’re so creative, I love how your mind works.”

Nora’s attention turned to Jack expectantly. “You’ve been quiet, what do you do other than be Mr. Strong Silent Type?” with a wide grin and innocent giggle.

“I’m not much of a storyteller,” Jack said with characteristic understatement. “I just build things.”

Marcus chimed in, “You mean built the whole foundation of the company ... this guy...”

“Ooo tell me,” Nora insisted, leaning toward him. “I want to hear about that, you must be a big deal.”

Jack’s face lit up despite himself. “Well, when StarPhire was just an idea, I built the entire infrastructure from scratch. The payment processing system, the security protocols, the API that handles billions of transactions...”

“Wait, you built all of that?” Nora was beaming with admiration. “By yourself?”

“Well yeah, at first it was just me, but I’ve got teams of teams now. I sorta miss those early days sometimes. Lots of boring technical mumbo jumbo that I won’t bore you with, but it’s part of what gave us the edge. Speed matters in this business,” Jack explained.

“No, it’s super interesting, just way over my head,” Nora giggled again.

Jack waved her off with a modest, “It takes a team, I do my part I guess.”

She was touching Nate’s colleagues as they talked, leaning in, her body language screaming attraction.

Nate had tried to join in with his story about catching a discrepancy in risk reporting at his last job. His story had trailed off as he realized how quickly he lost everyone’s attention.

“I designed a whole mitigation strategy that saved the product launch from having to get pushed back probably six months...”

But the guys had just politely nodded while his voice grew quieter and more uncertain.

As story time wrapped up, the afternoon sun beat down while they relaxed by the pool. The alcohol was making everyone looser and more flirtatious. Nate’s face was getting redder and redder, as he watched her flirt with his coworkers. He noticed Nora lean into whatever anecdote Tyler was regaling her with, her fingers tracing patterns on Tyler’s arm.

“Babe, you should put on some sunscreen,” Nate blurted out, cutting into the conversation.

Nora blinked and looked over at him. “Huh?”

“Sunscreen, you don’t wanna burn.”

“Oh ... yeah, um, yeah sure,” she said with mild annoyance at her conversation being interrupted.

“Let me get some on you.”

“Yeah fine...”

He started applying sunscreen to her shoulders and back with gentle, caring motions. But as he got more confident with the touching, emboldened by the alcohol and desperate to assert some kind of dominance after being overshadowed all day, his hands began to wander.

Gradually working his way to her sides, his thumbs “accidentally” brushed the sides of her exposed breasts. The contact sent electricity through him. He’d been watching her tits bounce and sway for the last hour, and now he was finally getting to touch them.

“Nate, just the shoulders please,” Nora said initially.

“I’m just being thorough, gotta protect you,” he insisted, getting increasingly aggressive as the alcohol and sexual frustration took over. His hands lingered longer than necessary, gradually becoming more bold.

Soon he was openly groping her tits under the pretense of sunscreen application, his greedy hands cupping and squeezing them while the guys watched. The smooth lotion made his hands slide easily over her skin, and he couldn’t resist massaging and kneading her breasts.

“Nate, stop it,” Nora said, getting annoyed at being groped publicly.

But Nate was past caring. The combination of alcohol, sexual frustration, and desperate need to mark his territory made him ignore her protests. He squeezed more lotion into his hands and continued groping her tits, rolling her nipples between his fingers.

Alex stepped in. “Hey man, come on, she’s clearly uncomfortable.”
