Been on a real Bonkai kick lately, realized it was because I was totally craving writing something a little darker, so I've pumped out a couple chapters (so I'll be able to update this monthly, as is with most my fics), and have a good sense of how and where this is going! Plus, smut. Beautiful, beautiful smut mwahaha

Cherry1: Glad you like it so far!

Bonnie woke up sore. She rubbed her eyes moved her legs. She was wearing her clothes from the previous day, hardly underneath the covers.

The more she woke up, the more she realized that the soreness was entirely in her upper thighs and between them. Wearily, she wondered if Elena had convinced her out again, and if maybe she'd tried to get lucky, despite the pounding headache of the-

Bonnie sat up with a jolt. The magic headache was all but gone.

She threw off the blanket over her legs, a mixture of panic, relief, and strange excitement coursing through her body. There, on her inner thigh, the proof of last night; dried, crackling as her legs moved, the salty tang lingering in the air for just a second.

As she got up to go to the bathroom, it all came rushing back.

She wet a washcloth under the faucet, warm water, and rubbed her skin clean. Then, she turned on the shower, since she just wanted to erase Kai's touch from her body completely.

She caught sight of herself in the mirror. Bonnie paused, hiking her cami up and the waistband of her underwear down to look at the bruises that painted her skin like watercolor on a canvas.

They were ugly and purple, fingerprints digging into her side, large palms blooming onto her stomach. Her lip was split, blood caking on the outside of the wound. It looked like she got in a fight with a wolf last night.

Or a vampire…

A shiver ran up her spine, setting her baby soft hair on her arms upright. It wasn't a shiver from disgust or from fear, as she entirely thought it was, but it was the thudding in her heart that made her feel like she was going to vomit. It was the excitement, the cool sweat right before having sex, when she got really turned on.

Angrily, Bonnie threw her top somewhere behind her, getting into the shower before it was warm. She immediately grabbed the soap, furious for finding that sexy, for enjoying what had happened yesterday.

You know, I think you might get off on pain a little bit too…

Kai's batshit crazy assertion bounced around her mind. It was absolutely unimaginable. She got off on his pain, as in she enjoyed seeing him get exactly what was coming to him. The idea that she too found some sort of sick pleasure in the roughness was something she wholeheartedly refused to believe.

She'd enjoyed sex with Jeremy, and he was about as vanilla as they came. It might have just been their ages too, she acquiesced, but she recalled not a whole lot of deviation from the standard position. She'd always liked sex with him. And then with Enzo! They were sometimes a bit more exciting, but nothing near Kai's level of darkness, and she enjoyed that even more!

But you know that Kai was still the best lay out of the three you've ever had.

"No," Bonnie snapped out loud, "He wasn't. That's…"

She slammed her hand against the wall of the shower.

The sex had been good. Thank god. But it wasn't supposed to be enjoyable, it was supposed to serve a purpose. God willing, it did.

She spent a long time in the shower, until the water cooled down and ran cold. She cleaned every square inch of her body, used up the last of her soap she had sitting on the shelf.

When she got out, right as she was grabbing for her fluffy bathrobe, she saw herself in the mirror again.

She wasn't focused on the bruises this time, but instead her eyes narrowed thoughtfully as she traced her lithe figure. She placed a careful hand on her midriff, wondering if at this very second, her future child was taking root. She'd seen Caroline pregnant, she'd seen Elena pregnant. Somehow, though, she couldn't imagine herself pregnant.

Did she even want a kid?

She'd always imagined herself going the regular route to a family; you know, fall in love, get married, plan for a baby. She was planning for a baby, but that's about where it ended. Still, she couldn't help but feel settled in her decision. Had she been wholly against having a child, she would have worked harder to find a way out of it. As it was, she hadn't.

And a part of Bonnie, a part that reawakened this morning, admitted she was looking forward to it.

She was a Bennett. She didn't need a man to raise a child.

Bonnie started looking for a new apartment two weeks after the night that she did not think about. Or, tried not to think about.

Living in a studio for one person was fantastic. The perfect amount of space, nothing wasted. Just enough room to drag herself from her bedroom space to her kitchen to her bathroom, not much more.

Babies? She may not be a pro, but she knew they took up a lot of space.

Jesus fucking Christ, she was already thinking about babies, as in plural, compared to just one baby. Damn the Gemini and their insane penchant for twins. No other witch coven in the world, as far as Bonnie knew, had that going for them. She supposed when you were one of the most magical leading families, something probably had to be a little screwy.

She started by just browsing Zillow at her bed at night, scrolling through new places around town. Two bedrooms, at minimum. Maybe a backyard. A town house? Could she even afford a starter home, maybe?

Kai was donating half of this equation. Could she rightfully ask him to pitch in? Geminis were pretty rich, she'd been slowly discovering that.

But did she want any of his money? She wasn't even sure she wanted his kid, but yet, here they were.

After narrowing down a handful of options, Bonnie enticed Caroline and Elena out to hunt abodes with her. She cited her decision to move that the current landlady was selling the apartment complex to a hotel chain, causing her to have to find other living. It was a white lie that wasn't a big enough deal to have her friends bother fixing it. Caroline had offered to compel the landlady, but Bonnie had brightly pointed out that maybe it was time for a change.

Elena always had good taste in apartments. Caroline was here because she instinctively looked for baby-traps, even without knowing it. And Bonnie needed to know that.

When Caroline pulled a face at location number one, and then pointed out with a pinched look that there were a lot of outlets very close to the ground, it was something Bonnie had hardly considered. Or, when Caroline examined a banister on a loft apartment Bonnie thought was damn near perfect, she waved one finger at it, and off-handedly said it was just about the perfect fit for a toddler to stick their head between and then get stuck. And then, she was the first to notice in the fourth location that the ground was uneven- the carpet sticking weirdly out- and a baby was likely to trip waddling across it, and could seriously hurt themselves. She always would apologize, but Bonnie could not tell her how grateful she was for these tips.

She'd have to tell them eventually, but that seemed like a far point away. She couldn't let them know she was intentionally looking for a new place due to a baby, it had to be more of an organic thing. An accident, as far as they knew. With a stranger. Who couldn't be tracked down at all. Never. Ever.

Still, Bonnie wanted perfection. She might end up raising this kid in the house forever; her Gram's house had been the place where her mother had been born and raised. Her grandmother had perfected it and never found a compelling reason to leave. Bonnie would consider herself so lucky if that happened to her.

Slowly, her future started to mentally take shape. A part of Bonnie wished she wasn't quite so excited.

XXxxXX

When her period came that month, Bonnie was unsure if she was thrilled, relieved, or utterly disappointed. She sat on her toilet, fingers pressed to her lips, trying to wade through the onslaught of feelings that had washed over her.

Part of these emotions were due to her totally out of whack hormones, obviously. Underneath that, there were some genuinely confounding feelings.

She was relieved, sort of. In the sort of way that even if you were excited for something new and scary, pushing it back sort of gave you a breather. It reminded Bonnie of getting college acceptance letters in the mail. She'd gotten a big letter from her school of choice, only to open it and find out she'd been waitlisted. As disappointed as she'd been, she'd also been sort of happy. It was out of her fingers, but she also knew that some decision had been made. She wasn't waiting in limbo. She'd gotten in eventually, but those days in between had been a strange mixture of fluxating anxiety and calmness.

After the relief, Bonnie realized that disappointment followed on the tail. Right after, tacked on, and immovable. It was the emotion that stayed with her, that kept on her back as she cleaned up, mechanically got dressed, and went to find some Advil.

Looking for that apartment, ruminating on a possible child, actually trying...it was like something in her mind had been flipped.

Bonnie had always considered herself pretty maternal, in an average high-school way. She'd always been kind and caring, a great babysitter. Plus, she felt like keeping up with Elena and Jeremy had forced her hand to a quasi-mom friend. Then, when Caroline had her twins, Bonnie had always loved making them laugh and smile and taking the pair of Caroline's exhausted hands for a few hours. It's not like she was rushing to be a teen mom, but she definitely had that mothering spark deep within her.

But it was like, of late, someone had set those dry kindling ablaze.

Perhaps it was that she had come to terms with it. She had fully expected to be late, and then later, and then for her period to never come. She had made peace with it. She'd started thinking of baby names and lingering at Target next to those impossibly small baby shoes.

Well, she tried to tell herself, they gave it a good try. Didn't work. Been tested. Time to move on.

Except for the fact that the magical headache was back by noon that day.

Bonnie wasn't getting out of anything.

XXxxXX

In the eerily silent town center, Bonnie stopped off by the fountain to splash some water on her face, locking her jaw as the insistent ringing heightening in the back of her ears.

Four months. Four measly months was all time time she managed to avoid coming back here.

She'd thought that she'd put off the initial calling for a year, she had at least that much time.

But no, she'd caved. She really didn't think she'd be able to make it to that fifth month.

Maybe it was because the stone had already been set in motion, the wheels rolled. She'd begun this now, and magic was nudging her to finish. No, not nudging.

Freaking shoving with a taser, more like.

In that time, Bonnie had prepared. She'd gotten one of those handy iPhone apps that tracked her period. It told her that today- and tomorrow- she was at the biggest risk for getting pregnant. She told herself she did this so she wouldn't have to come back again.

This time, she was really going to just get it done with.

On top of that, Bonnie had been busy with spellcasting and object imbuing.

She'd found a vial of Kai's blood in the wreckage of the old Parker mansion. They kept the blood of all the Gemini Leaders for posterity, which sounded really freaking creepy, unless you were a witch. Blood was like gold, she'd come to realize, and it was always a good thing to have on hand.

Tinkering with Kai's blood had given her a purpose, a tether to keep her away from the Prison World. Unfortunately, she'd finished her little project two days ago, meaning that there was no good reason to put this trip off, especially when it coincided with that red alert on her phone so precisely.

She'd done this once, she told herself. She could do it again.

Kai hadn't moved from where she left him, and didn't look too worse for wear. Four months hardly shriveled a vampire. He was probably hungry as hell, but still looked as handsome as ever. Arg, did she say handsome? She meant annoying.

"Knew you'd be back," Kai croaked with that annoying, haughty smile.

"Oh, did you?" Bonnie raised her eyebrows, frustrated.

"Well, when it was obvious that we need to just try," His tongue flicked out to lick his lips, over his fangs, "A little harder," His eyes trailed down to her stomach, still flat.

Bonnie didn't know why, but she instinctively went to cover it.

"You managed to make it four months. Impressive," Kai continued, lazily turning his electric gaze over to her, "But did you ever consider once how it was for me? Since I wasn't desiccated this time? This magical imperative that's like bad tinnitus? It's fucking pressing against my skull like a drill, Bonster. And I'm not exactly in a position to do anything." He rattled his chains. Good, still in those.

Bonnie barked out a harsh laugh, "You're lucky if I think of you at all."

"Now don't be cruel," Kai cooed, "You've been at the centerfold of all my sexy dreams. I bet it's the same for you."

Bonnie managed to keep her face unflushed, despite the shiver that ran up her spine. She'd never admit this to him, of course not.

"How do we even know it's going to work?" Bonnie asked, crossing her arms, "You ever consider you're just," She made a gun motion with her finger, "Shooting blanks?"

"Yeah, nope," The 'p' popped off his lips with a casual shrug, "Because magic wants this. Magic doesn't fuck up that bad. Plus, you wouldn't be here too if you truly thought that."

She'd caught him. She'd gone over the possibility in her head a thousand times that this was all a mistake and that there would never be a magic kid from this. But all her ends led her to this; magic did as magic wanted. It could almost give her a virgin birth, if it didn't have a fantastically magical father candidate tied up for her here. She was sure if Kai was dead, perhaps it would.

"Fine," Bonnie agreed, but soured and frustrated. More sexually frustrated, because once again, all other sex was completely vile and unpleasurable. Magic was getting her hooked on Kai, like some sort of dangerous new drug. She shouldn't want him so badly, she shouldn't feel like she needed him to finish, but here she was.

"Maybe it was the position," Kai said out loud, "Chairs are super fun- you ever have throne sex? It's good- but I can assure you I'm much better in other ways."

Bonnie stalked up to him. Perhaps for the first time, Kai realized that Bonnie had come without seemingly anything. No blood bags, no purse, no...nothing. His confusion was present in knitting his brows, just for a second.

"I hate to say it," Bonnie inhaled hard, "But you're right. Don't let it get to your head."

Kai was beaming, "Too late."

She grabbed his shirt, digging her nails a little too hard into his chest, probably leaving half-moon marks if not drawing blood. Kai sucked air through his teeth, but his eyes flashed with lust instead of pain.

"Oh, yeah, harder babe," He whispered, half-attempting to make her feel gross, but half-seriously. Bonnie considered slapping him, but he'd probably like that too.

"Phasmatos Motum Corporium," Bonnie began to whisper. The air around them swirled, like a tornado racing through the room. Kai listened to her chant three times before a light turned on in his eyes, understanding, and he echoed. She began to feel her skin fuzz, like she was being covered in soft cotton plants drifting in the air. It was only present for a second before the pressure around them and the softness sharply vanished.

Bonnie opened her eyes inside the modest house they'd transported to.

"Impressive," Kai commented, "But we knew that you were powerful af. That's something kids say these days, eh? 'AF'?" Still, as he blabbered, his eyes roamed around the room.

Bonnie went to grab her bag, which she'd pre-dumped at this location. The chair was garishly placed in the middle of the pastel living room, juxtaposed and awkward looking. Not quite as out of place as Kai, however, who was trying to figure this all out. The change of scenery and all, specifically.

Bonnie snapped a pair of sturdy metal braces on his wrists before unlocking him.

"Don't make me regret this," She threatened.

"Yeah, you say that," Kai said, standing. He wobbled, steadying himself on the arms of the chair. His legs shook like a newborn foal, "But this is like handing a pyro a matchbook and saying to just light one. You're setting yourself up for failure, whatever this is." He tapped the bracelets, "Because I think you forget I'm a siphon."

"Oh, I couldn't forget that," Bonnie threw him a blood bag. Just one, for now. He tore into savagely, his chin soon dripping and his fangs glinting in the light of the house lit up, "But it's special, just for you. You see, I've spent the last few months studying your blood, the siphon blood...and then reversing it. Anytime you try to use suck up magic, it just takes it away, makes you weaker. You try to suck away the enchantment off those, they retaliate and knock you out. You'll never get them off. Not without me."

"I've taken what I needed from you before," Kai replied, his eyes dark.

"Not without my consent though. There's the kicker. I added in the 'Consent Caveat'." Bonnie purred. Kai looked like a petulant child, "I've set wards up around here too, which if you try to take down, the bracelet will do their job. You can use basic magic within these walls, and you'll have free range of it. I think I'm being very generous."

"Sorta. Why?" His question caught her off guard. She wasn't sure, since it was a logical step. Why had she unchained him, albeit with this new more compact and precise chain? Why was she letting him live under a glorified house arrest? Why was she offering him this kindness, this humanity?

"You said it yourself. Sex is better with more movement." She replied, though it was a stupid, weak answer.

Kai snorted, starting to walk. He went to the kitchen sink, turning the faucet to wipe his face, dirtying one of the nice towels with blood. Then, just to see, he magically cleaned it.

"I almost came right there," Kai turned to her, "I've missed magic."

Maybe he'd allow her a pass too, and drop the question. Give her more time to figure it out. She'd been so focused on the how the why had gotten a little muddled along the way.

"I gotta hand it to you, Bons," Kai rubbed his wrists, "This is pretty ingenious. As far as I can see, foolproof. But on the other hand, I know if I did manage to escape this, you'd stake me faster than I could say 'Dracula'."
"Got that right." Bonnie muttered.

"I'm not in a position in my life where I need to break rules, fuck the stipulations laid out and all. Still, kudos," He raised his wrists, shaking them slightly, "I'm impressed. Which is good. Never thought about having kiddos, since my grand plan was to take over the family. Not really looking forward to giving up this intense power. But, now that I am going to, I like that it's you. Not some half-witted bimbo- who may have fantastic tits- but shitty brains and shittier magic."

"You don't have to look forward to anything," Bonnie reminded him, "I'm raising it. Her. Them." She fumbled through titles.

"So you say," Kai didn't sound convinced, "So. Sex?"

He flitted before she could blink, standing behind her. His nose pressed against her neck, his hands on her waist. She could still smell the lingering metallic tang of pennies on his tongue, the bloodbag's last drops rolling in his mouth.

Kai jolted them forward, into the wall. Bonnie felt herself flattened between the wall and Kai's body, his length already hard and pressing against the curve of her ass.

"You may have taken the lead last time, and I let you," Kai whispered, his voice deep and silky, "But what is they say to kids? Sharing is caring, right?" He said, his intentions obvious.

His noise ran up and down her neck. She could hear his fangs click out, and his teeth lightly grazed at her neck. She felt the tiniest pinprick from his bite on her neck.

"Hell no," She hissed, shaking her head.

"But Bonnie, you smell so good," Kai whined, "You smelled fantastic back when I was human, of course- god, how I wanted to fuck your brains out in the first Prison World, especially when you were sweaty and pissed at Damon- but now that I'm a heretic? Mhh, I don't know how any guy could resist you."

Kai grasped her arms, pulling them behind her, taking the control. He shoved her a bit harder, enough so that her shoulder blades ached from the stretching, "But you should have realized already, I'm pretty damn selfish. I was even selfish back then with you. You're my kryptonite, babe."

"Is that supposed to sound romantic?" Bonnie snorted.

"In its own way, if you want." He bit her ear, not hard enough to draw blood, but enough to make her jump. Kai laughed, his hips rocking against hers. He was almost dry-humping her like a teen on the wall of his new kitchen, and Bonnie was enjoying it.

As his lips circled over her neck, Bonnie shoved back hard.

"No biting me, no drinking," She snapped, "You said it yourself. I can't expect you to have control."

"Just a little taste?" Kai pleaded, "It drives me mad, ever since that little bit I had with your split lip last time. Ambrosia, I swear it."

"Absolutely not," Bonnie stood firmly.

Kai scowled, "Maybe in time," He said. Bonnie firmly thought that when hell would freeze over, but whatever. Let him think that if it helped him sleep at night.

"I've taken off work. I have two days to get pregnant, okay? So we're going to have multiple chances and take them."

"Christen the house?" Kai perked up, smiling. Of course he was. She'd basically just told him they were going to have a wild sex marathon.

"Basically. Now, I picked out this house and there's a very tempting bed up stairs and-Malachai!"

"You know when you say my name like that," Kai teased as he lifted her up without warning, "It makes me hard."

"Everything makes you hard lately it seems."

"Everything you do, yeah, to be precise," Kai said, setting her on the edge of the dining room table, "And while I'm sure the bed upstairs is heavenly- mhm, pillows, what a thought- I think I want to have you right here first. A man's gotta start with his food first, eh?" He asked.

Bonnie, almost tempted to roll her eyes and drag him upstairs, decided to let him have this. She spread her legs, leaning back and grinning, "Well, what's stopping you then?"

Kai's fingers gripped her knees, rubbing rough circles over them as he spread them further, "You hardly have to ask me twice," He assured, "I'm going to take you as many ways as I can before you go. For science and the best results, of course," He added cheekily.

Bonnie swallowed, "For the end goal, yes," but somewhere not as deep as it was the first time, dangerous close to the surface, Bonnie couldn't help but stop the flare of excitement that was rising up inside of her.

Basically, I think it's because I watched Heathers/listened to the musical, and that dark love is just so tragic and so much resting on my mind. I've already started mapping out a Heathers x BK story called 'Chaos Killed The Dinosaurs, Darling'.
