After Hours, Greta Begs for His Filth

The forty-second floor had emptied an hour ago. The HVAC hummed like something trying not to be heard. Anton, forty-two, stayed at his desk with his sleeves rolled and his wedding band catching the lamp every time he moved the mouse. The merger deck was almost done. His wife thought he was being responsible. She always thought that.

Greta didn't leave with the others.

She was twenty-two, a recent college graduate with a mouth that cut and a temporary assistant badge that still looked new. His wife—her mother—had asked him to give her a few weeks of office experience after college. Anton had said yes because refusing would have sounded like guilt. Three weeks of not looking at her knees under the conference table. Three weeks of hearing her say his name soft when the door shut and professional when it didn't.

She set a fresh coffee on the corner of his desk and didn't step back.

"You don't have to stay," he said.

"I know." Her voice was low. The city glittered behind the glass. The office was only them. "I've been waiting for the building to empty since Monday."

He looked up. That was the mistake. Her blouse was open one button past anything he could explain to a board. Her eyes were steady. Twenty-two and done pretending.

"Greta."

"Don't use that tone." She came around the desk, close enough that he smelled perfume under the coffee. "The one you use when you want me to remember you're married to my mom. I remember. I've remembered every night since I turned eighteen and realized the man in our kitchen made my stomach drop."

His hand tightened on the mouse. The ring bit.

"You grew up in that house," he said, and hated how thin it sounded.

"I was eighteen," she said. "Grown. Legal. And I still didn't touch you. I went to college and I thought about your hands on a steering wheel and I hated myself and I came home anyway. Four years of keeping my mouth shut while I got my degree. I'm done." She set her palm on the desk beside his. "I fantasize about you. I have since the week I turned eighteen. Not a day before. I need you to hear that. And I need you to stop looking at me like I'm still somebody's little girl when we both know what this room feels like after hours."

The heat had nowhere to go. His wife was across the city, trusting him with the stepdaughter who wasn't his by blood and was his by a vow he was already cracking just by listening. Greta didn't blink.

"Say something," she whispered.

He didn't. Not yet. The want sat in his chest like a live wire, ugly and exact, and the empty office held it.

Greta dropped.

Not a stumble. A choice. Her knees hit the carpet in front of his chair, and the sound was small and final. She looked up at him with her hands on her thighs, not touching him yet, asking with her whole body.

"Stop treating me like a daughter," she said. "I don't want the careful voice. I don't want the distance. I want to be the filthy little secret you think about when you lock this door. Use me like that. Please. I'm not your kid. I never was your blood. I'm a grown woman on her knees because I want your cock and I'm done waiting for you to admit you want mine."

"Get up." His voice cracked. "Greta, get up. Your mother—"

"Is not here." Her fingers found the hem of her skirt. "And she doesn't get to police what I do with a body that's mine. I'm asking you. I'm begging you. If you want me to leave, say it and I'll leave. No scene. No threat. But don't pretend you haven't been hard under this desk all week while I bent over your files."

He had. God help him, he had. The refusal sat in his mouth and tasted like a lie he was tired of chewing.

She didn't wait for it. She spread her knees on the carpet between his shoes and dragged the skirt up her thighs until the black panties showed. A wet spot darkened the center, obvious, obscene. She hooked a finger in the fabric and pulled it aside, shameless, showing him how slick she was, how the lamp caught the shine on her pussy.

"I've been wet all week," she said, clear and filthy, holding herself open so he couldn't look away. "Thinking about your cock. Thinking about you bending me over this desk and fucking me like you don't give a damn whose stepdaughter I am. I touched myself in the bathroom on Tuesday and I had to bite my wrist so nobody heard your name. Look at me. I'm dripping for my stepdad and I'm not sorry. This is me saying yes. This is me begging."

Something in him snapped. The careful man—the executive, the husband, the stepfather who kept his hands in his pockets—went somewhere he couldn't follow. He stood so fast the chair rolled into the credenza. He caught her chin, not rough enough to bruise, firm enough that she gasped and smiled like she'd won.

"If we do this," he growled, "we do it raw and nasty. No sweet. No pretending you're anything but what you're begging to be. No condom. No kindness unless you ask for it. You want filth, you'll get filth. Say you want that. Say it plain so I know you're choosing it."

"I want that," she said, immediately, eyes bright, no hesitation in her. "I want you. I consent. All of it. Raw. Nasty. Don't hold back on me, Anton. I've been begging in my head for years. Do it out loud."

He hauled her up by the arms, spun her toward the desk, and the last of his resistance died against the heat of her skin.

Anton bent Greta over his desk and the merger deck went everywhere.

Slides fanned. A pen hit the carpet. He shoved her skirt to her waist, dragged the soaked panties to her knees, and the sight of her hit like a fist—twenty-two, bent for him, ass up, pussy shining on the same desk where he signed his wife's cards. His cock was already out, thick and aching. He didn't tease. He lined up and pushed in, one hard stroke, raw, no latex, exactly as nasty as he'd promised.

Greta cried out, grateful and broken, and braced on the wood. She was tight and dripping, taking him to the root.

"Fuck—Anton—"

"Say it right." He gripped her hips and fucked her deep and mean, the desk thumping the glass. "Say what you are while I fuck this dripping pussy."

"Your dirty stepdaughter," she gasped. "I'm your dirty stepdaughter and I'm taking your cock like a slut. Harder. Don't be nice. I didn't stay late for nice."

He gave it to her. Wet sounds filled the empty office, her cunt sucking him every time he slammed back in. She dripped down his balls. Every thrust knocked a moan out of her she didn't swallow. He leaned over her back, mouth at her ear, fist in her hair. He yanked her head back and watched her mouth fall open in the dark window, a ghost of the two of them, his suit pants at his thighs, her bent and used and loving it.

"Married man. Your mother's husband. Bent over my desk begging. Filthy little secret. That's all you are tonight. Say it again."

"Dirty stepdaughter," she sobbed, pushing back, ass smacking his hips. "Degrade me. Use me. I've wanted this cock since I was eighteen and legal and stupid for you, and I don't care."

He fucked her until her thighs shook and she came with a wrecked cry, pussy pulsing, milking him, soaking a quarterly report. He didn't stop. He rode her through it, meaner, talking filth while she begged for more.

"Coming on your stepdad's cock like you were built for it. Your mom thinks you're helping with footnotes."

"Flip me," she laughed, breathless. "I want my legs open. I want you to look at what you're doing to me while you rail me."

He pulled out. She went onto her back across the desk, papers stuck to her sweat-damp blouse, panties at one ankle, pussy open and swollen and shining. He caught her ankles and pinned her legs wide, knees toward her shoulders, and drove back in. The slap of his hips was filthy. She clawed at his shirt and begged him not to slow down, voice cracking every time he bottomed out, her pussy fluttering, greedy, dripping onto the blotter. He railed her, merciless, the angle brutal, his cock hitting deep enough that her mouth fell open on his name.

"Choke me," she begged, guiding his wrist. "Light. I want your hand on my throat while you fuck me. Use me like the forbidden slut I am. Tell me I'm disgusting for wanting my stepdad's cock. Ruin me on this desk."

He wrapped his hand around her throat, pressure careful, thumb under her jaw—enough to own her, not enough to steal her breath. She nodded, frantic, yes, eyes locked on his, and he squeezed in time with his thrusts.

"Legs spread for the man who sits beside your mother at dinner. You're a nasty little stepdaughter whore, and you'll take every inch until I decide you're done. Wedding ring on the hand around your throat. Feel it. Say thank you."

"Thank you," she whined, smiling like a sinner. "Thank you for fucking your filthy stepdaughter. Don't be gentle. I begged for this. I want your cum on my tongue and on my face. I want to taste what you think of me when you stop pretending."

"Filth," she panted, barely able to form it. "Give me your filth. Call me your secret. Tell me I'm nothing but a wet forbidden hole for my stepdad after the building goes dark."

He fucked her harder. The desk creaked. He yanked her blouse open, shoved her bra up, and bit a nipple, sharp, not sweet. She jerked and flooded around him. Her second orgasm hit while he had her pinned and lightly choked, eyes rolling, sobbing his name and stepdad in the same breath—more, harder, don't stop, I'm your dirty girl, give it to me.

His control frayed. The ring on his finger, the facedown photo of his wife by her elbow, her cunt gripping him like she meant to keep him—all of it shoved him to the edge.

"On your knees. Mouth open. Take it like you begged."

He pulled out, shoved her to her knees. She hit the carpet eager, tongue out, looking up like worship and sin. He stroked his slick cock twice and unloaded. Thick ropes of cum striped her tongue, her lips, her cheek, a hot line across her nose. Heat striped her skin. The taste hit her tongue, salt and him, and she didn't close her mouth until he was finished painting her. She moaned and held still, grateful and wrecked, until he was shaking and empty against her lower lip.

"Thank you," she said, cum on her teeth when she smiled. "Thank you for finally giving your stepdaughter exactly what she craves."

She leaned in before he could step back and licked every drop of his cum off his cock, slow and thorough, a wicked, satisfied smile on her messy face. Her tongue traced the underside, the head, the shine she'd made of him, until he hissed and had to brace a hand on the desk.

"This is only the beginning," she whispered, looking up, cum still shining on her cheek and her lashes. "Our dirty after-hours secret. I'll stay late whenever you want me. You don't get to pretend this didn't happen."

He watched her rise. Watched his beautiful, cum-covered stepdaughter straighten her skirt, tug her panties up over the wreck of her pussy, and button her blouse with shaking fingers. She didn't wipe her face. She wanted the elevator mirrors. She walked to the door with a sway in her hips that said she knew he was staring, knew what they'd started, knew it would burn his marriage to the ground if anyone on the forty-second floor ever learned what this office sounded like after hours.

She smiled like a woman who had already won, and left him there with his cock wet and his ring too tight.

He was already ruined, and she hadn't even made the elevator.
