**Chapter 2: Late Night Files**

Emma just stared at the clock on her monitor: 8:47 PM. The office was now a ghost town, just the low hum of the AC and the occasional creak of the building settling. Most people had left a few hours ago , heading home to actual lives. She should have been one of them. Instead, she was buried in the wreckage of the Thompson campaign.

The client had hated the latest visuals. “Too safe,” the email had said. “Make it edgier.” Edgy. Right. She’d spent the afternoon scrambling, reworking copy, swapping images, and now the whole deck was a mess of half-finished slides and caffeine stains on her notes. Eyes burned. She rubbed them, smearing a bit of mascara, and sighed.

The encounter with Marcus earlier kept replaying in her head like a bad loop. His fingers inside her in the copy room, that filthy whisper calling her his slut. The taste of her own arousal on his skin. She’d gone straight to the bathroom afterward, fixed her makeup, and pretended nothing happened. But her body remembered. Every time she crossed her legs, she felt the ghost of that ache.

*Focus, damn it.* She clicked save on yet another version and stood up to stretch, her pencil skirt riding up her thighs. The floor was quiet enough that her heels echoed as she headed to the copy room for fresh printouts. Maybe seeing the layouts on paper would help.

She pushed the door open and froze.

Marcus was already inside, leaning against the counter with a stack of papers in one hand and his phone in the other. He looked up, that damn smirk sliding into place. His tie was loosened, sleeves rolled up, showing those forearms that shouldn’t have affected her like this.

“Working late, little sis?” he asked, voice low in the small space.

Emma’s heart kicked up. “Don’t call me that here. And what are you doing? This isn’t even your floor.”

“Helping.” He held up the paper drafts of the Thompson pitch, marked up in red pen. “Ryan forwarded me the disaster. Figured you could use a hand. Or… something else.”

She snatched the pages from him, cheeks heating. “I’ve got it under control.”

“Clearly.” He stepped closer, backing her toward the humming copier. The door clicked shut behind her. No lock, but the room felt sealed off from the empty office anyway. “You’ve been squirming in your chair all day. Bet that pretty pussy’s been wet since I left you hanging earlier.”

Emma swallowed hard. She wanted to deny it, to shove past him and get back to work. But the way he looked at her hungry, amused, like he already knew every dirty secret made her stomach flutter. “Marcus, this is insane. We’re stepsiblings. I work here. You’re… consulting or whatever.”

“Yeah, and you came running when I told you to meet me this afternoon.” His hand brushed her waist, then slid lower, palming her ass through the skirt. “Good girls don’t do that. But you’re not really a good girl, are you?”

She shivered as his fingers kneaded, pulling her hips against him. He was hard already; she could feel the thick outline pressing into her belly. “Please. Someone could walk in.”

“Everyone’s gone. Even the cleaners finished.” He nipped at her ear, breath hot. “Now tell me the truth. How many times have you touched that needy little cunt thinking about your big stepbrother?”

Emma’s breath hitched. His hand slipped under her skirt now, fingers tracing the edge of her panties. She was soaked again had been for hours. “I… I don’t”

He pressed two fingers against her clit through the fabric, rubbing slow, firm circles. “Don’t lie. I saw how you looked at me during that family trip two summers ago. You locked yourself in the bathroom for twenty minutes after I took my shirt off by the pool.”

God, he remembered that? Her face burned with shame and something hotter. The pressure on her clit built, making her hips twitch. “A few times,” she whispered finally.

“Louder. And be specific.” He pushed her panties aside, sliding one thick finger along her slick folds but not inside. Teasing. Always teasing.

“More than a few,” she admitted, voice shaky. “Maybe… ten? Fifteen? After that dinner when you first moved in. And the pool. And that time you came home for Christmas and wore that stupid tight sweater.”

Marcus chuckled darkly, rewarding her with a finger sinking deep into her pussy. She gasped, gripping his shoulders. He pumped slowly, curling just right to hit that spot that made her knees weak. “Fifteen times? Bullshit. I bet it was more. Bet you came moaning my name into your pillow like a desperate whore.”

“Marcus” Another finger joined the first, stretching her. The wet sounds were obscene in the quiet room. She rocked against his hand, chasing the friction, her breath coming in short pants.

“Say it. Tell me you’re my filthy stepsister slut who fingers herself thinking about me fucking her raw.”

The words stuck in her throat, but the building pressure made her reckless. “I’m… I’m your filthy stepsister slut,” she breathed. “I touch myself thinking about you.”

“Good girl.” He kissed her hard, tongue invading as his thumb found her clit. The pace quickened rough, relentless. Pleasure coiled tight in her belly, so close, so fucking close after hours of frustration.

Then he stopped. Pulled his fingers out completely, leaving her clenching around nothing, right on the edge.

Emma whimpered, hips bucking forward uselessly. “No please, I was almost”

“Ruined,” he finished, sucking his fingers clean with a wicked grin. “Just like this afternoon. You don’t get to come until I say so. Builds character.”

She glared at him, thighs trembling, frustration burning hotter than the arousal. Her clit throbbed painfully. “You’re an asshole.”

“Yeah, but you love it.” He straightened her skirt for her, almost gentle, then stepped back. “Finish your campaign. I’ll be around tomorrow. And Emma? Next time you stay late, I might not stop at just fingers.”

He left her there, the door swinging shut behind him. Emma leaned against the copier, breathing hard, body buzzing with unspent need. The Thompson slides suddenly seemed impossible. All she could think about was his touch, his voice, the way he made her feel dirty and alive.

She printed the damn pages anyway, hands still shaking. On the way back to her desk, she wondered how much longer she could pretend this was under control.

It wasn’t.

Emma’s hands were clammy on the steering wheel as she pulled up to her parents’ mansion. The place still felt too big, too perfect sprawling lawn, marble foyer, the kind of home that screamed “new money” even five years later. Mandatory family dinners happened once a month, and skipping this one wasn’t an option. Her mom had texted three times already.

She smoothed down her modest navy dress the one that hit just above the knee and buttoned high enough to look respectable. After last night’s ruined orgasm in the copy room, she’d barely slept. Her body still hummed with frustration. Marcus hadn’t texted. Just that smug look as he left her dripping and desperate.

Inside, the smell of roasted chicken and herbs hit her. Her mom, Elena, bustled around the dining table with wine glasses. Richard, Marcus’s dad, was already pouring drinks. And there was Marcus, leaning against the kitchen island in a casual black button-down, sleeves rolled up, looking annoyingly relaxed.

“Emma! Sweetheart, you’re late,” her mom called, pulling her into a hug. “Marcus was just telling us about his flight back.”

Marcus’s eyes met hers over Elena’s shoulder. That smirk. “Yeah, long trip. But it's worth it to be home with my family.”

Dinner started normally enough. Small talk about work, the weather, some cousin’s upcoming wedding. Emma sat across from Marcus, which felt like a trap. She pushed food around her plate, hyper-aware of his foot brushing hers under the heavy oak table.

Halfway through the main course, while Richard was droning on about golf scores, Marcus’s hand disappeared beneath the tablecloth. Emma stiffened as his palm landed on her knee, sliding up her thigh with zero hesitation.

She shot him a wide-eyed glare. *Stop.*

He didn’t. Fingers crept higher, pushing the hem of her dress up. Her mom laughed at something Richard said, completely oblivious. Marcus’s touch was casual but firm, tracing the edge of her panties. She was wet again. Pathetic.

“Emma, honey, you’ve been so quiet,” Elena said. “How’s that big campaign going?”

Marcus chose that moment to slip two fingers under the lace, stroking her slick folds. Emma gripped her fork tighter. “It’s… fine. Busy. Lots of late nights.”

His middle finger circled her clit slowly. She bit the inside of her cheek to keep from gasping. The risk made everything sharper the clink of silverware, her stepdad’s voice, her mom refilling water glasses while her stepbrother fingered her under the table like it was nothing.

“You should take breaks,” Marcus said smoothly, voice perfectly normal. “Don’t want to burn out.” He pushed one finger inside her, then two, curling them just right. Her thighs trembled. She was soaking his hand, the wet sounds barely masked by conversation.

Somehow she survived dessert. When everyone stood to clear plates, Marcus finally withdrew his fingers. He met her eyes and slowly licked them clean behind his wine glass. Emma’s face burned as she excused herself to the bathroom.

She locked the door, breathing hard, panties ruined. Part of her wanted to scream. The other part wanted him to finish what he started.

Back at the office around 10 PM, the floor was dead quiet again. Emma had driven straight there after dinner, telling herself it was to grab forgotten files. Bullshit. She knew why she came.

Marcus was waiting by her desk, jacket off, tie gone.

“You’re playing a dangerous game,” she said, voice shaky as she approached.

He didn’t answer with words. He grabbed her by the waist, spun her around, and bent her over her own desk. Papers scattered. Her dress hiked up roughly. “You’ve been teasing me for five fucking years, little sis. Time to pay up.”

Emma’s heart pounded. “Marcus, the cameras”

“Disabled them earlier.” His hands yanked her panties down to her ankles. Cool air hit her dripping pussy. She heard his belt buckle, the zip of his pants. Then the thick head of his cock nudged against her entrance.

He didn’t ease in. One brutal thrust and he buried himself balls-deep. Emma cried out, gripping the desk edge. He was big — stretching her, filling her completely.

“Fuck, so tight,” he groaned, pulling back and slamming in again. “This is what you’ve been craving, isn’t it? Your stepbrother’s cock ruining your perfect little cunt at work.”

“Yes,” she whimpered, shame and pleasure twisting together. He set a punishing rhythm, hips slapping against her ass. The desk creaked under them. Each thrust pushed her forward, her tits pressing against the cold wood through her dress.

He reached around and rubbed her clit hard. “Say it. Tell me what you are.”

“I’m… I’m your slut,” she gasped between moans. “Your filthy stepsister whore.”

Marcus growled in approval, pounding harder. He grabbed her hair, pulling her head back so he could bite her neck. “Louder. Imagine if Mom and Dad knew their precious Emma was getting fucked like a cheap office whore right now.”

The degradation pushed her over. Her orgasm hit hard walls clenching around him, legs shaking. She tried to muffle her cry against her arm.

He didn’t stop. “Good girl. Now take my cum.”

A few more deep thrusts and he came, flooding her pussy with hot, thick spurts. He stayed buried deep, grinding through it, making sure every drop stayed inside.

When he finally pulled out, Emma stayed bent over, cum already starting to leak down her thighs. She felt wrecked. Used. And terrifyingly satisfied.

Marcus tucked himself away, then helped pull her panties up, trapping his mess against her. “Wear it home. Think about me every time it drips out.”

She straightened slowly, legs wobbly, adjusting her dress. Mascara smudged. Hair a mess. “This can’t happen again.”

He laughed softly, kissing her forehead almost tenderly. “We both know that’s a lie.”

Emma grabbed her bag and left without another word, the sticky warmth between her legs a constant reminder as she drove home. Her stepbrother had finally claimed her. And the worst part? She already wanted more.

Emma barely slept. She tossed and turned until the sheets were tangled, the sticky remnants of Marcus’s cum from the night before long dried but impossible to forget. Every shift in bed reminded her. By morning, she’d showered twice, but the shame clung tighter than any scent. *Your stepbrother. At work. On your desk.* She stared at her reflection while applying concealer over the faint hickey on her neck. A scarf would have to do.

The office felt different when she arrived brighter lights, sharper edges. Or maybe it was just her nerves. She kept her head down, answering emails on autopilot. Her thighs still ached faintly from being bent over. When Sarah, her assistant, popped in with coffee, Emma forced a smile that felt cracked.

“You okay? You look like you pulled an all-nighter,” Sarah said, freckles bunching as she frowned.

“Campaign crunch. You know how it is.” Emma took the mug, grateful for the distraction. She avoided the conference room where Marcus was supposedly in meetings. Avoided the copy room entirely.

Around 11:30, her desk phone rang. Ryan’s extension. “Emma, my office. Ten minutes.”

Her stomach flipped. Ryan Caldwell didn’t do casual check-ins. Performance reviews were scheduled weeks out. This felt… off.

She smoothed her black pencil skirt conservative today, high neckline and knocked on the heavy glass door to the corner office. The view behind him was all city skyline, gray clouds pressing low.

“Come in. Close the door.”

Ryan sat behind his massive desk, salt-and-pepper hair perfectly styled, gray eyes sharp as ever. Mid-forties, built like he still lifted heavy weights on weekends. He gestured to the chair across from him. No smile.

“You’ve been doing strong work on Thompson,” he started, flipping through a folder. “Numbers look solid. But I’ve noticed some… distractions lately.”

Emma’s mouth went dry. “Distractions?”

He leaned back, studying her. “New consultant. Marcus Hale. You two seem familiar. Family connection?”

She shifted in the seat, crossing her legs. The motion pressed her sore pussy against the chair and she had to bite back a wince. “Stepbrother. Our parents are married. It’s not a big deal. Professional as always.”

Ryan’s lips twitched, almost amused. He stood and walked around the desk, perching on the edge closer to her. The scent of his cologne something expensive and woody filled the space. “Professional. That’s interesting. Security mentioned some late-night activity on the floor yesterday. And you came in this morning looking like you ran a marathon in those heels.”

Heat crawled up her neck. She tugged the scarf tighter. “I stayed late on the deck. Like I told Sarah.”

He didn’t blink. One hand reached out, adjusting the scarf slightly. His fingers brushed her skin, deliberate. “Hickey. Amateur move. Marcus?”

Emma’s heart hammered. Lying to her boss. To *Ryan*. “No. It’s… nothing. Bad date last weekend.”

“Bad date.” He repeated it like he was tasting the words. His voice dropped lower. “You’re a talented woman, Emma. Ambitious. I’ve watched you climb. But ambition can make people sloppy. Careless with secrets.”

She swallowed, pulse racing between her legs despite the guilt. Or because of it. Ryan had always been intimidating commanding in meetings, decisive. Now that energy felt heavier, more personal. His eyes flicked down to where her skirt had ridden up slightly.

“I’m handling it,” she said, voice steadier than she felt. “Marcus is just helping with the European angles. Temporary.”

Ryan hummed, not convinced. He stayed close, towering over her seated form. “Temporary. Sure. But if he’s distracting you… affecting your focus…” His hand rested on the back of her chair, thumb grazing her shoulder. “I might need to get more involved. Personally.”

The implication hung there. Emma’s mind flashed to Marcus bending her over the desk last night, filling her, calling her his whore. Now Ryan, watching her like he could see every filthy detail. Her nipples tightened under her blouse. *What the hell is wrong with me?*

“I appreciate the concern,” she managed. “But I’ve got it under control.”

“Do you?” He tilted his head, gray eyes darkening. For a second, the professional mask slipped just enough for her to glimpse something hungry underneath. “Because you’re flushed right now. Breathing a little fast. And that scarf isn’t hiding much.”

She stood abruptly, chair scraping. Too close. The air felt thick. “Was there anything else for the review?”

Ryan let her step back, but his smirk was knowing. “Not today. But keep your head in the game, Emma. I’d hate to lose you over something… messy.” He paused at the door as she reached it. “And tell your stepbrother I expect full discretion. Or I’ll handle the oversight myself.”

Emma nodded and slipped out, legs unsteady. Back at her desk, she buried her face in her hands for a moment. Guilt gnawed at her Marcus’s cum from last night, the lies, the way her body reacted to Ryan’s probing stare. She was spiraling.

Her phone buzzed. Marcus: *Dinner aftermath got you thinking about round two? My place tonight.*

She deleted it without replying. But the ache between her legs said otherwise.

Across the floor, she caught Ryan watching through his glass wall. He didn’t look away.

This was getting too complicated. And the worst part? Some twisted part of her was already wondering what “more involved” from Ryan would feel like.
