A/N: Here's a one-shot I wrote based off a dream I had of my favorite ship. BonKai. I posted the story to my Tumblr page and wanted to give FF a go. These guys slay me with their chemistry. Since I can't have them in canon, I'll take them in fanfic. WARNING: Dark!BonKai, crude language, smut, noncon for those who don't want to read. Please do not read if not your cup of tea.

I do not own the Vampire Diaries or any of its characters.

My intentions for coming to the witch tonight had been reasonable, legitimate in the beginning. Fuck with her mind while siphoning off just enough magic to leave her incapacitated in the face of my new family. Lilly Salvatore and the heretics had plans for the witch and Mystic Falls. Me, I had plans for the Gemini Coven and I needed her magic to see it all finally come to fruition.

She looked young sleeping on her side with her hand tucked underneath her chin. Almost innocent and untainted. A few tendrils of her hair partially covered her heart-shaped face. Her verdant eyes rapidly moved behind lids fringed with the longest natural lashes I'd ever seen.

We were similar, Bonnie and I, in that we both never got to enjoy our teen years. High school classes, sporting events all took a backseat to the supernatural. Her parents never took the time to be a healthy presence in her life while her so-called friends used her at every turn to fix their jacked-up lives and be the savior for a town that was a supernatural magnet and never appreciated the sacrifices she made to keep it safe. I can only imagine what it was like growing up in the shadows of two narcissistic girls who barely held a candle to her. I suppose being used could imply some modicum of need albeit small and shallow when it comes to Bonnie's friends.

My worthless parents took great pains to remove me from their lives. So, I had killed every last one of my siblings or so I had thought. Liam and Liv were fortunate enough to escape death with the help of Jo. But their hatred of me developed long before my killing spree. My parents and coven had despised me because I was different, an abomination, a parasitic pariah to their magical bloodline, hell bent on being its leader.

A familiar rage burned in the center of my chest. I inhaled deeply as the sudden urge to release the pent-up energy overtook me. I shook the pesky annoying feelings away. I wasn't an impulsive wanna-be psychopath. There was a method to my madness, a purpose to my existence. Revenge. Plain and simple. And my little witch was a means to that end. The reminder helped return my attention to the reason I was standing in a dimly lit college dorm room. Bonnie Bennett. Unfortunately, she was the only person in the world able to shake and lay waste to two decades of plotting and planning.

Intent on completing what I had set out to do, I shed myself of my black coat and laid it on a nearby chair. She whimpered in her sleep and hope sprung up in my gut like a geyser that it was me she dreamed of. Slowly, I approached the twin bed. I toed off my shoes then climbed in, careful not to disturbed her slumber and pressed myself against her, chest to back, hips to the plump swell of her backside.

My arm reached around her and I clasped the hand that laid nestled beneath her chin. Immediately, I tensed as the first strains of Bennett Magic seeped through my pores and filled me with a warmth similar to the smooth trailing burn of liquor. The front of my pants tightened as I lengthened and strained against the restricting fabric. Bonnie's magic was addicting and like a fiend, I wanted more. A moan slipped from her and I closed my eyes as the sound shot a bolt of desire straight to my dick. I couldn't help the groan that rumbled through my chest as she wiggled her delectable ass against the hard bulge in my pants.

So, enthralled by the sensations she wrought in me just from spooning her, I missed the moment when she woke. I pressed my hand against the flat plane of her stomach to keep her against me. Now that I know the feel of her, I was in no hurry to let her go. The lights flashed and the eclectic collection of knickknacks that adorned her desk shook. I could feel her magic bouncing off her in waves like a pulsar as she fought to recall and nail down one spell, any spell to get me away from her.

"Surprise Bon-Bon," I whispered then quickly rolled her beneath me.

"What da hell? Kai!" she shrieked, struggling to get out of my embrace.

"Just here to thank you for that little stunt you performed in the 1903 prison world. Thanks to your deceit, I made a lot of new friends."

A flash of fear swept across her face and was gone before I could appreciate it.

"They love witches and –," I bent down to run my nose along the pulse at her neck. "And blood." The shiver that ran through her was so strong, it reverberated through my own body.

"I guess I should have you to thank for that," I continued taking advantage of her silence. The salty tang of her skin made my mouth water as I licked toward her clavicle.

My warrior witch cringed but that didn't keep her from voicing her displeasure.

"Cut the crap, Kai. If you're going to kill me do it. But you better make damn sure I'm good and dead because I will make you wish that you had remained locked up," she hissed as determination set in her jaw.

"No, Bonnie," I said my traveled from her face to the globes of her breasts that lifted and fell with every breath she took. "There's something else I desire more than your death at the moment."

I swooped in and swallowed her scream with my mouth as I tried to draw her very life from her with a kiss. I ran my tongue along the tightly pursed seam of her lips, demanding entry.

"Open," I said against the Cupid's bow of her mouth. If I wasn't so consumed by the taste of her, I would've laughed at the shock upon her face as she opened her mouth to me. "

"Good girl," I said then pushed my tongue inside. The feel of hers against mine was a heady sensation. I delved in deeper sweeping the contours of her mouth sipping every drop of the nectar within. With a mind of their own, my hips rotated and pressed against hers causing her to shriek into my mouth. My hands, hungry for the feel of her skin gripped the black tank she wore and ripped it away from her. She fought me then. Tiny fists beat against my back followed by the rake of her fingernails on my face. She ceased when she saw the wounds heal right before her very eyes.

"No." She shook her head in denial.

"Yes," I replied with a dark chuckle. "You see Bonnie. You can't stop me and Mystic Falls won't be able to stop what's coming."

"You asshole. I hope you fucking enjoy this because I'm going to kill you."

The fire in her eyes confirmed her words were more of a promise than threat.

"I intend to, Bons."

I made quick work of the flimsy yoga pants, tossing them carelessly to the floor. She kicked and bucked beneath me. Her hands made a half-assed attempt to burn my back but I merely thought of a countering spell rendering her efforts useless.

As a precaution, I uttered an immobility spell as I divested myself of my pants. My gaze roamed over her pert breasts and narrow hips. She was breathtaking. My cock lurched and stood erect at the sight of her.

One would've expected fear but Bonnie regarded me as one would an insolent child.

"You don't have to do this, Kai. Let me go and I won't tell the others that you're back."

I sighed then cocked my head to the side. "You misunderstand me. I want to do this. Truth be told I've wanted to fuck you ever since that day I cornered you in Damon's car."

I take measured steps toward her. She rose and strained against her magical bonds. The image she made, splayed out like a blood offering just for me had me almost spending myself before I'd even been inside of her.

"I will have my revenge against my family," I continued. My voice sound deep and husky to my ears. "I will desiccate the vampire you call friend. And right now, I will have you."

I grabbed her ankles and yanked her legs apart, exposing her to my appreciative gaze. The magic held her in place. I knelt before her as if I were now worshipping at her altar. Her spicy, musk scent assailed my nostrils and I bent over to take that glorious bundle of nerves into mouth and tortured it with my lips, tongue and teeth. I watched her while I feasted.

Her teeth bit into her plump lower lip as tears streamed down her face as her hips rose to meet the incessant jab of my tongue. Not only did I want to taste her, but I longed to touch her, stroke her. I inserted a finger into her and was mesmerized by the inner walls that squeezed and held me tightly within. I added another digit then another curving them in search of that special spot. A mewling sound was all the direction I needed. My fingers stroked her while my tongue took languid laps at her clit. Her walls fluttered around my fingers and my other hand pressed her down into the mattress as her orgasm nearly set her to flight. I greedily gobbled up her release. Moaning at her distinct flavor.

Anxious to be inside her, to feel her vaginal walls clench around my dick, I clamored over her and covered her body with mine.

I hissed at the first contact of flesh against flesh. She felt like the eye of a turbulent storm; of peace and tranquility. I sunk into her and wanted to remain there for as long as I could. Surprised that I didn't take her like the beast demanded I should. But she wasn't having it.

Her body twisted and bucked to dislodge me from her tight warmth. The movements sent a thrill of ecstasy down my spine and straight to my balls as I thrust deeper into her. A part of me, that pesky side that was clearly remnants of my weak little brother told me this was wrong. That this was Bonnie. My enemy. My equal. My glory. The first person ever in my life to make me feel something other than death and carnage. She was good, sacrificing and loyal to a fault.

It was these qualities that the beast in me strived to overtake, devour and consume. I marveled at the fact that she was still fighting me, even as her body quivered and clenched around me in an explosive orgasm. It was delicious and powerful nearly driving me to completion. But I wasn't finished with my little witch. I grabbed her throat and pushed her head back, exposing the lovely column of her neck. The pulse at the base beat a rapid tattoo as she struggled against the lingering twinges of her climax.

I placed whisper soft kisses along her neck. I tasted the salty trail of her tears and inhaled her scent. She smelled of honeysuckles, the earth, power and I'm sure a smug grin spread across my face because she smelled of me. My gums itched at the possessiveness that overcame. It was foreign and unfamiliar as a tension developed deep in my abdomen. This glorious witch despite her obvious disdain for me was mine and no other would have her, not even that whipped pitiful excuse of a vampire she called friend. The image of the two of them together, her smiling up into his face caused my incisors to extend to their full length. Jealousy, I hated to admit, was the fuel behind my urgent pelvic thrusts. My magic jerked her arms up high above her head, renewing her struggles beneath me.

"Stop, Kai!" she demanded. Never pleaded.

But I couldn't. I was a demon possessed by a need, an insatiable hunger and I was determined to stake my claim upon my witch. My hands roamed down the contours of her body squeezing and gripping at places where they could, then I reached under to cup her ass providing a sloping angle that allowed me to push deeper into her if that was at all possible. There was a gasp and a moan and I wasn't quite sure which of us made the sounds. A tingling sensation tickled the fringes of my brain then exploded into an excruciating pain that felt as though every blood vessel in my head was rupturing. I laughed despite the pain.

"That's right, Bonnie. Make me work for it."

And before she could yell out some hateful retort, I tore into her neck and drank. Undeniable pleasure filled my mouth. Her body clenched around me once more. I disengaged my incisors, reared back with one final thrust and experienced an orgasm that had me feeling on top of the world, exposed and vulnerable all at the same time. I pumped my hips, spilling as much as I could into her, wanting above all else to leave something of me behind. I collapsed on top of her as I waited for my breathing and my dead heart to regulate.

Somewhere through my orgasmic induced haze, I hear my witch mumbling but I was too spent, too relaxed to care or even noticed that her hands were free and were scorching a trail of fire down my back. Before I could utter a counter spell, she was gone and I was engulfed in flames. Laughter burst from my mouth as I allowed the flames to lick over my skin for a moment. The burning pain was nothing compared to the intense pleasure I took from her and I looked forward, no yearned, for the opportunity to do so once again.
