A/N: This is part 3 to office smut/Boss!Killian.

I've had this in my documents for a while and thought Father's day would be the perfect time to post an Oh Daddy fic. Enjoy!

He can't stop thinking about her. Just the imagery in his head of her makes him hard. Unbearably hard. He sits at his desk in the office, wondering when the day will ever end. They can usually entertain one another with casual conversation via texts when they aren't busy. Today isn't one of those days, though.

What makes matters worse is his nights are constantly filled with naughty dreams. Life outside of work has been busy for them both lately, and it's been a week or more since they were last together. He refrains from counting the days. That would only add to his frustration.

When he gets a free moment, he picks up his phone and begins punching out a long message. It's definitely a bad idea because he doesn't have any innocent things in mind to say. But he can't stand it any longer.

After several minutes of considering his words and typing out a carefully crafted message, Killian hits send and waits for her response.

K: I woke this morning needing to fuck you until you could barely breathe, much less remember your own name. I need to mark you, ravage you, make you scream my name until the only thing left inside you is my cum and the knowledge you belong to me. I need to fuck you. Hard. To own your body in a way you'll never forget. I need to make you cum until it hurts. And then make you do it again. I need to feel your need and hunger to submit to my own. I need to feel your body helpless beneath mine.

E: Oh my God, Daddy…I want to feel you pinning my wrists down Please...

His cock throbs painfully in his pants. He wasn't expecting her to reply like that. But he knows she's aching for release just as much as he is.

She's always the one calming things if he gets a little too friendly at work, and he's thankful for it. He wouldn't want anyone to think he's showing her favoritism, so they've had to keep things between them a secret. Ruby is the only one who knows, but only because she figured it out on her own. Luckily, she's cool about the situation and says she ships them, which he thinks means she approves.

K: Fuck. Do you prefer me pinning you or tying you down?

E: Pinning, Daddy. Any time you pin me, it gets me hot.

Killian smirks and tucks away her confession for later use. He knew pinning Emma's wrists drove her crazy and he does it quite regularly in the heat of the moment. But he's never realized how potentially effective it could be, warming her up first.

K: Mmm. As much as I enjoy pinning you down, I prefer having my hands free to make proper use of my possession.

One hand strays from the phone and goes to his lap, gripping the stiff bulge in his pants as he wonders if Emma is touching herself, too. Wonders if she has to pause from her work to try and satiate the ache she feels for him. He wishes he could see her right now. Her cheeks flushed, her lips parted.

E: I like when Daddy commands me not to move.

Killian shivers at the thought of Emma obeying his command to stay poised for his use.

K: I love that too, baby. I really fucking love that. It always makes you cum. Hard.

He rubs his thickness through his clothes. He's so fucking hard, it wouldn't take much for him to explode in his pants.

E: God I want you. I want to hear more.

K: I'm tired of texting, love. I need you. Right now.

E: Killian…

He can practically hear her moaning and pleading in his ear, hear that desperation and need in her voice. He groans, quickening the pace of his hand, desperately feeling the urge to undo his pants and finish himself off. His fingers are trembling, and he can barely type out a response.

K: I want to bend you over my desk and take what's mine.

E: Daddy, please... I want to hear you growl against my ear as you yank on my hair.

Emma keeps staring at her phone, waiting for a response that never comes. His texts have made her so hot, she had to refrain from slipping her hand inside her skirt and touching herself. It's very difficult to resist. She can't even concentrate on work, but it feels like it's been forever since she and Killian have made love. She needs him so badly, it's making her crazy.

When she hears her office door close, she's so lost in her thoughts, she flinches and drops the phone. She knows it's Killian without having to look up. She can feel the hunger and heat radiating off him.

He locks the door and stares at her, his eyes hooded and dark. She clenches her thighs together, her heart staggering at the way he looks at her. As though he needs to have her now, or else he'll keel over and die.

Before she can react, he pounces on his prey. He grabs Emma by her wrists and tugs her out of her chair, spinning her around to guide her face-first against the back wall of her office. Emma shudders in his tight, suffocating hold.

He stretches her wrists high above her head with one hand and grabs a handful of her hair with his other, gently tugging her head back as he growls a whisper against Emma's earlobe. "Don't you dare fucking move."

Emma whimpers softly, his deep, husky voice vibrating against her eardrums and pulsating all the way to her toes, heat surging through her entire body. She's so fucking turned on right now. "Daddy..." She tries to summon the will to resist, but simply can't. Honestly, she's not trying very hard. The increasing wetness pooling between her thighs is a testament to that.

"I will take what's mine,"

he growls.

Still pinning her wrists firmly against the wall, he drags her skirt up her legs with his other hand, forces her thighs apart and reaches between her legs to grip her firmly. Emma gasps at the sudden feel of his rough touch on her nub. Her thong is fucking soaked, and she knows Killian can feel the wetness through her panties.

He cups her pussy in his hand, one finger slipping under her thong and through her slit. "Tell me who this belongs to, baby girl."

She tenses, her breaths sharp and ragged. She knows they shouldn't be doing this in her office, but at the same time, she wants this so damn much. "Oh, God…"

Killian pulls his hand back to spank the smooth flesh between her thighs, ending the swat with a tight grip on her mound.

Emma bites her bottom lip to stifle the sharp cry threatening to rip from her throat as she grinds against his hand, gasping for air.

"I can do anything I want to my baby girl. And why is that, Emma?" he prompts, knowing the confession will make her melt.

She visibly trembles, panting sharply. She's gushing with wetness. "You own me... " she whimpers. "I'm yours."

"Exactly," Killian whispers, his breath hot on her skin as he softly kisses her cheek. He maintains a tight grip on her wrists as he strokes the soaked fabric over her aching heat, his fingers feathering her clit. "Now be more specific. What else belongs to me?"

Emma struggles to find the air in her lungs, her entire body flushed with pink. She turns her head as much as Killian's control over her will allow and gazes into his eyes, their lips almost touching. "My cunt belongs to you, Daddy."

"Yes, my love," he growls. "Your pretty cunt belongs to me and only me." Killian smirks wickedly and kisses her softly,

whispering against her lips, "And your exquisite cum does, too."

Emma gasps and returns her gaze to her wrists as Killian burrows his face into her neck, nipping at her skin as he breathes in her scent.

"And I know you're ready to give it to me." He lifts his head to growl in her ear. "You smell so fucking delicious."

Emma whimpers softly, desperately, and writhes against him and the wall. Killian's words make her shiver in the best way, and she feels her wrists slipping down from his grip.

"Ah ah," comes the reprimand, and he pulls back his hand to spank the heat between her thighs once more, causing Emma to gasp out sharply.

Her body jerks against his and melts as the punishment is accentuated by the tender brush of Killian's lips over her neck.

"You were told not to move," he whispers sweetly and smiles as she presses her wrists into his hold. He rewards her effort by stroking her pussy once more through her panties. "Good girl."

"Killian, please," Emma whimpers, arching her hips into his touch.

Killian pulls his hand from between her thighs and wraps it around her hair, giving her a gentle yank as he presses his stiff erection into her ass, pinning her firmly into the wall.

"Would you like permission to cum, baby girl?" He gives her hair another tug, jerking her head back again. With a low growl, he sinks his teeth into her neck and sucks firmly, marking her instantly.

"Yes!" Emma cries desperately, loving how Killian makes her feel helpless in the bout of his hunger, loves how he pins her against the wall, waiting to use her however he wants. She is so incredibly wet for him. The fresh mark on her neck makes her thighs slick with arousal as she sobs out his name. "Killian..."

"All you need to do is ask permission, love." He tenderly kisses the spot where he claimed and moves both of his hands to her hips, leaving her wrists unpinned, but she keeps them pressed against the wall. Tucking his fingers under the band of her thong, he pulls at them and slides the skimpy fabric down to her knees. The cool office air fans her flesh, but in no way cools the lust she feels for this man.

"Don't move your hands. You will stay in your place, " he demands in a dark, husky tone as he rubs her clit.

Emma moans, growing wetter by the second. "Please! Can I cum?"

The last word comes out in a squeak as Killian growls and shoves two fingers into her waiting cunt, his thumb feathering her clit. "Aye. Give me what belongs to me, baby girl," he growls, fucking her fiercely. "Cum for your daddy!"

Emma screams, her body responding eagerly to Killian's command, the pleasure ripping through her, causing her back to arch and her body to submit to the overwhelming pleasure pounding through her veins. She presses her wrists to the wall and opens her mouth wide to cry out his name. "Killian..."

"Shhhhhhh! Not so loud, my darling Emma." He clamps a hand over her mouth, rhythmically working his fingers in and out of her dripping heat, coaxing her body into another orgasm. "Do you want everyone to hear me make you cum?"

Unable to hold back, Emma whimpers into his palm from the blinding pleasure, unable to respond any other way, thankful Killian's control muffles her cries. She squirms against his hold, twisting and straining desperately. The pleasure is so intense, but she somehow focuses on her wrists, determined to exert her will to keep them in place no matter how much of a struggle it is.

"No stopping now, baby girl," Killian whispers against her skin as he sweetly kisses her shoulder and along the column of her neck. His soft lips are a vast contrast to the rough treatment he's giving her cunt as he continues to finger fuck her. She screams again as she feels a third finger in her cunt.

"You know you're mine, love. Daddy demands every drop. You will cum until it's the only thing you know how to do."

She can't breathe. All she can do is buck her hips and cum as Killian's honeyed voice sends powerful vibrations to her core.

"Can you keep quiet on your own, beautiful?" A crooked smile spreads over Killian's lips when she looks over at him.

Emma's eyes roll back inside her head as she surrenders to the lust taking over her. He drifts his hand from her mouth, drinking in the shaky gasps escaping her lips. He rips open her blouse with both hands, the buttons popping off and bouncing off the wall and onto the floor. She lets out a soft moan when he kisses her cheek and slides his hand down her body, tracing over the smooth dip of her stomach. He reaches underneath her skirt and cups her sex, his middle finger finding her swollen clit, circling the heated bud, working toward a steady massage.

"Don't you dare stop cumming, and keep those hands where they belong."

Emma's eyes go impossibly wide, and she jerks uncontrollably, gushing over Killian's fingers. "I can't," she whines, struggling with her hands as the spasms ripping through her body erase every last ounce of control.

"Stay still," Killian growls and spanks her clit, causing her to buck and twist sharply against him.

Emma bites into her lower lip in an effort to hold back the cry threatening to expose their activities. Killian only intensifies his assault, flicking her clit and plunging his fingers inside her as he sinks his teeth into the crook of her shoulder.

She gasps, knees threatening to buckle. She's cumming even harder now, and through the ecstatic haze clouding her mind, she realizes the pain in her fingers must be from desperately grasping at the smooth wall in a vain attempt to brace herself by clinging to something, anything.

"Killian..." she wheezes a plea, desperately needing his cock inside her.

Killian growls and removes her hands from the wall so he can pull off her blouse. His fingers, slick with Emma's wetness, tangle in her hair as his other hand gently wraps around her throat. He wrenches Emma away from the wall, maneuvering her around and bending her over the desk. She tenses in anticipation as she grips onto the edge of the desk for purchase. She doesn't have to wait long.

Possessed with lust, taking only the time to unzip his pants and pull out his unbearably stiff cock, Killian lifts her skirt the rest of the way above her waist, grabs her hips and enters her without warning, claiming her fully with one savage thrust.

Her mouth opens in a silent scream that shakes her to the core as he pounds into her mercilessly. She moves her hips with his, willingly and eagerly taking everything he gives her. She's so unbearably wet and tight around him, it's almost too much; she struggles against the myriad of sensations.

"Cum!" Killian orders.

Emma has no choice but to obey.

Her walls spasm around his thick cock, and his bruising grip on her hips makes her work for every breath. He bends over her, his strength claiming her as he bites her shoulder again. He fucks her hard and rough, stretching Emma's clenching walls around his length, her extreme slickness making it easy for Killian to slide in and out of her.

He tangles his fingers in her hair again and arches her head back with a tug. With a subtle shift, he moves his other hand from her hip and slides it around her body, pushing her bra cups out of the way and firmly taking her breast in his palm. His thumb and finger play with her aching nipple, making her whimper and writhe restlessly underneath him. Killian removes his hand from her hair to take her chin and turn her slightly to face him as he whispers out his command before covering Emma's mouth with his own. "Cum, baby girl! Cum for Daddy."

She feels his powerful words travel from his lips to hers. The treatment he's giving her cunt as he pounds into her makes her whimper and scream into his mouth as she orgasms all over his cock. She couldn't stop the sensations ripping through her body if she wanted to. Her body belongs to Killian and will respond as he wishes, for as long as he wishes. She is so slick with sweat and cum, unable to breathe normally or think straight.

Killian slips out of her and turns her around, sitting her on the edge of the desk so he can watch her expression when he fucks her and makes her cum one last time. He removes her bra completely, flinging it to the floor, unbuttons his shirt and settles between the cradle of her creamy, soft thighs. He wraps one arm around her back and slides his other hand around her throat, eyes boring into hers as he slams into her roughly, enjoying the way her breasts bounce against his chest as he whispers against her lips. "Beg me to cum," he coaxes and kisses her forehead. "Beg me to fill you up. Beg me to own you," he demands and presses his lips to her forehead again. "Beg me to make it stop."

"Please! Oh god, please, Daddy!" she gasps out desperately as he roughly bucks his hips forward, thrusting into her. "Please, cum for me. Inside me," she pants. "Own me. Claim me. Please! I can't take any more!"

Her words send ripples of pleasure through him. He growls and moves his hand from her throat, holding her hips exactly where he wants them. His fingers tighten around her supple skin, Emma's body arches and all she can do is receive his cock.

His hips move erratically, chasing his release. "Once more. Cum with me, baby girl," he demands and slams into her until his cum spurts out in long, pulsing ribbons inside her perfect cunt.

"Killian," she whimpers his name over and over, the only word she can think of. Her body jerks and shakes on its own accord.

Dimly, she realizes her face is in Killian's hands and he's kissing her passionately. She melts into him, soft sounds escaping her lips as he kisses her. His hips slow to a lazy roll as Emma's cunt milks his cock for every last drop of cum.

"Oh gods, baby girl," he says gruffly against her lips.

"Killian..." Emma's voice is all moans and gasps and quivering breaths.

His lips are on her breasts and nipples in a steady progression of kisses, his breaths shattered against her slick skin. She shudders with random aftershocks as she pulls his mouth to hers, kissing him slowly and sliding her tongue against his.

Killian fights to catch his breath and takes an unsteady step away from her, waiting for his heartbeat to slow. The front of his pants is soaked with her juices, but he doesn't care. He sinks down into Emma's chair and guides her into his lap, cradling her body to his chest and softly stroking her hair.

"Fucking hell, love." His words are completely shattered.

Emma buries her face in his neck and tries to control her breathing as she snuggles close. Killian smiles and kisses the crown of her head as he strokes her hair. As his fingertips lightly caress her cheek, she can smell herself on him.

"I needed you desperately, Emma," Killian whispers and kisses her hair again.

"Me, too," she murmurs with a smile. She giggles when she realizes the condition Killian's pants must be in now. "I'm dripping."

Killian smirks and shrugs, too sated and tired to care. He wraps both arms around Emma and holds her close, murmuring sweet nothings as they wait for the office to empty so they can sneak out. Tonight will be a quiet one after their office antics, but he's already looking forward to next time.
