~~~

This was the fourth time this week that Kaneki had been cooped up in his office, overworking himself with no sleep. The raven haired man was stressed from all the paperwork he was being given, only being able to stay awake by cups of coffee.

Over the course of these days, you had noticed that he had been acting rashly. He was irritated more easily, broke things in frustration, and would loose his temper on the smallest of things.

As the man's girlfriend, you wanted to do whatever you could to help him, you just didn't know how.

You stood at the other end of Kaneki's office, stiring creamer into two cups of coffee. The only sounds being the clanking of the spoon against the cup, and the scratching of pen hitting paper. As you finished stiring the coffee, you walked over towards his desk, watching as he held his head in one hand, staring down at the papers.

You set the cup in front of him and sat in the chair in the other side of the desk. You watched as he picked up his head and leaned back. He took the glasses off his face and rubbed his eyes with his fingers. You noticed the bags under his eyes, and you immediately felt bad. Maybe you shouldn't have given him coffee.

You continued to stare at his tired and stressed state. There was no way he'd be able to continue working like that.

You drew in a deep breath "Kaneki?" He didn't look at you, just hummed as a response.

You got up from your seat, and walked over to his chair. You placed your hands on his shoulders. He removed his hands from his eyes and looked at you with a confused and annoyed expression.

You rubbed his arms up and down "you need to take a break. You're exhausted." Kaneki rolled his eyes and pushed your hands away "I'm fine. Could you go? I have work to do" you narrowed your eyes at your boyfriend. You turned him back towards you, roughly grabbing both sides of his face.

He glared at you despite his cheeks being squished. He didn't even look intimidating. You glared right back at him "take a break. Please." Kaneki grabbed you by your wrists and pulled them away from his face harshly. "Last time I checked, you don't tell me what to do. If you're just going to be here to annoy me, then leave" he turned his chair again back to his desk, but you brought your leg up and stopped it midway. Your foot resting between his legs.

You leaned down, grabbing him by his tie, and pulled him towards you. You smashed you lips against his and felt the way his body stiffened up.

His gasp was muffled against your lips as you pushed down on his shoulders and made him rest against the back of his chair. You climbed on his lap, lips still attached to his as you forced your tongue in his mouth.

He moaned softly at the feeling of your tongue rubbing against his own. He closed his eyes, kissing you back, attempting to fight for dominance against your mouth. You weren't having it, and brought your hand up, roughly pulling at his black strands of hair.

The force of which you pulled caused him to break away from your mouth. His head was lulled back as a cry of pain mixed with pleasure left his mouth.

Well, that's new.

You brought your mouth to his neck, pulling at his hair again as you sucked on the spot just below his ear. His mouth was agape as he got more and more vocal.

"God...yes, right there...hah...you're so good..." He panted out, tightly clutching at the arms of his chair. He gulped down the forming saliva in his mouth as he felt his trousers start to get tighter and tighter. "Mmm...ah... god, stop fucking teasing me."

You felt the bulge in his pants start to grow bigger, so you detached yourself away from his neck and brought yourself to the floor. You took a hold of his knees and forced his legs completely open. You placed your hand on his clothed area, pressing against it. You watched as his face contorted into pleasure, sweat gleaming on his forehead, as you palmed him through his pants.

Kaneki gritted his teeth and glared down at you, his cheeks flared red due to heat and arousal "I said...to stop fucking teasing me...listen to me for once in your life...". He continued to moan out, and he brought a hand up, running his hands through his sweaty hair, tugging at the locks.

Kaneki felt your hand travel from his crotch to his belt, undoing it and pulling it out of the pant loops. The belt his the floor with a metallic 'thud!' and he watched as you unzipped his pants, getting rid of the confinement they had. He let out a soft moan at the feeling of his hard cock being able to breathe.

Your fingers wrapped around the hem of his pants tugging at them. Kaneki raised his hips up just enough for you to pull them off, letting them pool around his ankles.

His hard on was fairly obvious once he was just in his boxers and undone button up shirt. Kaneki looked down at you with half lidded, lust filled eyes. His breathing was ragged as you pulled his cock out from the restraints.

He was slightly above average size. Not so big that you wouldn't be able to fit him at all, and not too small where he couldn't even fill you up. His tip was flushed red, pre-cum leaking out of it and going down his shaft.

Kaneki threw his head back with a loud moan as you attached your mouth to his tip, sucking on it. He bit his lip, trying to hold them back. He didn't want to alert anyone who may have been outside his office.

Kaneki bit his lip so hard he drew blood. You noticed how he was barley making any noise so you pulled away from him, causing him to whimper at the loss. Kaneki looked down at you and saw your slight glare.

You ran your hand up his thigh, rubbing it in soft circles before slapping it harshly.

Kaneki let out a yelp of pain "w-what the fuck was that?!" You narrowed your eyes at him "I didn't tell you to keep quiet did I? If you want this, make some god damn noise. You're usually so loud and vocal in bed, why are you holding back? Is it because you don't want to get caught? Not like you had any concerns about it when you were fucking me in a public restroom a few weeks ago"

Kaneki gulped, looking down at your cold gaze. His chest heaved up and down "I-I'll be more vocal...sorry..." Seeing him go from rude, sarcastic, and cold to submissive, flustered, and hot made you swell with a sense of pride. You took his cock in your hands "good boy".

You licked up his shaft from base to tip, which caused a long, dragged moan to escape the males mouth. You took him into your mouth finally, though there was still some that you couldn't fit into your mouth.

Kaneki moaned shamelessly as you bobbed your head up and down his cock. His hands made their way to your hair, pushing you down slightly to take in more of him.

He hit the back of your throat, causing you to gag, but you continued anyway. You felt tears prick the corners of your eyes but you still sucked on him. He needed this. He needed to destress.

Kaneki watched you as you sucked him off. Your eyes were narrowed, almost closed, and your cheeks were hallowed out in order to take more of him inside you. Kaneki's chest fell up and down rapidly as he moaned.

"Ah! Keep...going! Take it all in that beautiful fucking mouth of yours. Fuck...! Swallow every fucking inch of me, baby...! I'm yours! Hah, hah...mmm...fuck, you're doing so good...baby..."

Kaneki moaned loudly, bucking his hips up harshly to meet your pace. His mouth hung open as moan after moan came out, drool building up in his mouth.

"God...more...I want more...I'm gonna...- I'm gonna cum...fuck-!" His eyes shot open as you started to add pressure to his balls, your tongue covering evey inch of his dick that was in your mouth.

"Mm...mmm...fuck...I'm gonna fucking cum, baby~! Fuck...fuck! Harder! Harder!" Kaneki gripped your hair harder as his cum shot into your mouth in loads. You pulled off of his dick, swallowing his cum and wiping the excess off your lips.

Kaneki panted heavily, his breathing raspy and uneven.

You rubbed his thighs soothingly to calm him down from his orgasm. He whimpered softly as his head fell to the side. He looked at you, his eyes still filled with lust.

He swallowed down the forming spit in his mouth "get...get up here...so I can...can fuck you properly..." You stood and gasped as Kaneki grabbed you by your waist harshly, forcing you to sit on his bare lap, both of your legs on each side of his.

Kaneki began to immediately unbutton your blouse, practically ripping the buttons off completely. He tossed it off to the side, and his hands latched onto your breasts, squeezing them.

He leaned his face into your neck, his hot breath fanning your flesh. He licked up your pulse line, his lips sucking a purple hicky onto your neck.

His hands trailed from your boobs to the clasp of your bra, undoing it immediately and throwing it to the ground as well.

Kaneki gazed at you hardening nipples, and attached his mouth to your right breast, pinching your other nipple between his thumb and pointer finger.

You moaned softly as you buried your head into his sweaty neck. Kaneki bit your nipple, causing you to cry out in pain.

"I know you can be louder than that. Weren't you the one who told me that if you wanted this to make some god damn noise?" You bit your lip, silently cursing yourself at your own words being used against you.

You felt his tongue move against your perked bud, massaging it to ease the pain.

Kaneki's hands moved to the hem of your pencil skirt, yanking it down your legs along with your panties. He threw them on the ground, eyeing your now completely naked body on his. He undid his tie and fully unbuttoned his shirt, throwing them off.

Kaneki brought his hand down to your entrance, rubbing your clit with his thumb and sticking his middle and pointer finger inside you.

You rested your forehead on his shoulder, moaning and grinding against his hand. The wet sound being made because of it turned you on even more.

As Kaneki continued to stimulate you, you bit down on his shoulder, drawing a bit of blood. Kaneki hissed in pleasure, pushing his fingers deeper into you.

A knot began to form in the pit of your stomach and you clenched your teeth "K-Kaneki...I'm...I'm gonna...cum..." You whined as Kaneki suddenly pulled his fingers out.

You felt Kaneki smirk against your skin "I can't let you cum yet baby~ I haven't even given you the good part yet. You think you're ready for my cock?" You nodded. He always did this. He always teased you when it came to being inside you. No matter how much he loves it himself.

He chuckled "good. Because I'm ready." He grabbed your hips, lifting them as he lined his cock up with your entrance. You went down on him, letting out a moan as he filled you up.

Kaneki let out a soft groan, biting his lip as he felt your warm insides around his shaft.

You lifted your hips up halfway, slamming back down on his cock. Kaneki let out a strangled moan, shoving his face into your neck.

"God...you feel so good around me...baby...you feel so good around my cock". You continued to ride him as Kaneki thrusted his hips up to meet your pace.

"Take it...take it all... I'm-I'm gonna fuck you...so fucking hard... Fucking god, you feel so good..." He moaned and hissed out as your walls clenched around him, squeezing him.

"Hah...hah... Kaneki, harder...faster...!" Kaneki rammed up into you harder, the wet sounds of skin slapping against skin being made.

You let out a loud moan as Kaneki hit your G-spot. He seemed to understand why you had done that and thrusted harder into that spot. Both of you moaned loudly, panting against the others body.

The knot in your stomach formed again and you seethed. You felt yourself clench tightly around Kaneki's cock, which caused him to moan as well. You felt him twitch and pulsate inside you, which you knew as he was about to cum too.

Words didn't need to be exchanged, as you both knew you were almost out of energy.

Kaneki wrapped his arms around your waist tightly and clutched you against his body "faster, baby...fucking hell..." His nails scratched against your shoulder blades, leaving red marks that would sting like hell later. "Gonna fill you up...gonna fill you to the brim with my cum...baby... Yeah...gonna fuck you so fucking good..." His thrusts got sloppier as he was nearing his orgasm, as were you.

You rode him faster as you moaned out louder.

Suddenly you became undone, and came all over him. As you came, it was what triggered Kaneki to as well. His load of cum shot inside of you, and he panted and moaned. You fell against his body, exhausted.

Kaneki rubbed your hips, pressing kisses to the side of your head soothingly. He yawned and rested his head against your shoulder "tired?" You asked weakly. Kaneki nodded, too exhausted to make a comeback.

You smiled and petted his sweaty hair, raking your fingers through it and lightly scratching his head. He hummed against your neck and you felt the ghost of a smile against your skin.

"Sleep. You deserve some rest" Kaneki nodded and relaxed in your arms, slowly dozing off into a peaceful sleep.

You pressed a kiss to the side of his head and hugged his sleeping body, falling off into sleep yourself.

FUCK! Did I seriously just fucking write that?! That was my first ever smut omfg!!
