Bonnie picks up her underwear, realizing it's become a flimsy scrap of fabric and her brows furrows. Damon has been ripping her clothes heatedly, turning them into tattered rags ever since their arrangement started, and she's had to replace more than a few shirts and pants. Nothing fancy or particularly sexy, she doesn't even bother glancing at any lingerie because that would require interest in impressing Damon, which she doesn't have. He doesn't seem to care either, beyond a couple teasing comments that serve as meaningless banter. Maybe she should protest or drum up a fight about her clothes, but she has no energy for that, especially once his lips drag down her throat and his hands brush over her nipples roughly, any form of a sentence dying in her throat.

Bonnie slips on her navy skirt, picks up her bra off the floor and surveys the gritty gas station washroom. The mirror is shattered, multiple wall tiles are smashed in and the sink is cracked heavily, water dripping onto the floor. Damon is busy buttoning up his shirt, his hair windswept but his skin is clear, no trace of any scratches or lovebites. Bonnie tugs at her own neck, feeling raw skin and hickies and she wishes his skin was also marred, that she wasn't the only one left with traces of him on her.

"No use returning the washroom key. I bet the whole road heard us," Damon comments brusquely, and she glares at him sharply, wondering if he's trying to elicit a reaction out of her.

"You were the one who couldn't wait. You better hope I don't get an infection from this dump," Bonnie retorts, almost mechanically. After all, she can't say anything nice, that's not their thing. They communicate through biting remarks and arguments, they always have to put up a fight.

He frowns, not quite satisfied. "Don't be dramatic. You weren't protesting about my hand inside you when we were driving. It takes two to tango, BonBon."

"Whatever. Just take me home."

He's still frowning. "Don't be like that."

"I'm not being like anything. We had sex, what else is there to do? You wanna go destroy another bedroom in your house?"

If he wants another round, he'll put in the work. He can convince her, and she'll let him.

"Come on," Damon says softly, moving closer and grabs her hips, his grip almost bruising. He backs Bonnie against the sink, wolfish look on his face and sinks to the ground. Runs his hands down her thighs, pushing up her skirt and props one of her legs over his shoulder. She watches, her breath becoming shallow in anticipation as her nails dig into her palms. He brushes his lips against her cunt, and Bonnie releases a shaky sigh, arching into his touch. "I can help. I know what you want. Let me give it to you."

So, she does.

Bonnie rifles through her poke bowl aimlessly, half-listening to Caroline's explanations about her college courses. They're at a new place near Whitmore College at Caroline's insistence, who demanded a lunch together to catch up and gossip. Elena is busy with school, studying for tests and working on group projects. Bonnie is relieved it's just her and Caroline, given she's fucking Damon, and while she scrubbed her skin raw in the shower with an apple-scented exfoliator, she can't be sure that Damon's scent on her body is gone. She knows what she's doing is wrong, it's a serious breach of girl and friendship code - there is a dim feeling of guilt in her chest, but not enough to end things with Damon.

He isn't a good thing in her life, but he is the only one who can rouse any real emotion out of her, who doesn't require her to put up an act and she needs it. She craves it.

"Bonnie? Bonnie, are you listening?" Caroline waves a hand, sucking in her bottom lip confusedly and Bonnie blinks, faking a sheepish smile.

"Sorry, I spaced. My mind just got away from me."

"It's fine. I know school isn't the most exciting thing in the world…but do you think you might sign up for next semester? I think applications are open now. It hasn't been the same without you!"

"I'm considering it," Bonnie lies, "It would be nice to go to parties and live in the same dorm."

Caroline brightens. "Exactly! Seriously, enrol for next semester. You'll love it at Whitmore, Bon, I swear."

"I'll look into it." Another lie. They come so easily now, and it would make anyone's head spin, how many lies she tells a day. But not everyone is effectively ripped out of a peaceful afterlife.

"What else have you been doing with your free time? Anything exciting?"

She sleeps a lot. Watches TV. Has sex with Damon. Dodges phone calls and naps whatever she can.

"Just running errands for my dad and hanging out. Nothing worth mentioning."

"Have you, uh…talked to Jeremy at all? I know he mentioned reaching out sometime."

"Not really. We've both been busy."

"Oh."

"He did mean a lot to me, he still does, but I think our ship has sailed. Things changed, for both of us. It's just not the same."

Caroline studies her expression. "I guess so. If you ever want to talk about it more, or about anything in general, I'm always here. Please don't forget that. I still consider you to be my very best friend, and I'd hate to think that you feel as if you can't come to me for anything."

Bonnie smiles, but it feels plastic and stiff on her face. She knows Caroline is being sincere, but Bonnie can never tell her the truth. She will not admit to her friends that they damned her. She is still protecting them, despite the costs.

Bonnie stands in line at a Taco Bell, waiting patiently to order chilli cheese fries and a crunchy beef taco, her thighs sticky and she is sure her lips are swollen, her hair mussed, her neck covered in lovebites. It's late at night after a vigorous round with Damon that has left her surprisingly hungry, a feeling she usually ignores but is far too urgent at the moment.

She moves up a step and checks her phone. A few texts from both Caroline and Elena, a couple from her dad and one from Damon. She ignores them all and shuts off her phone, going back to waiting expectantly. She spots a group of teenagers cackling in the far corner booth, throwing fries playfully and their faces are crinkled with carefree joy. Bonnie studies them, their youth and optimism, but also their arrogance and innocence. It's foolish, she thinks bitterly, to be so ignorant but oh, how she envies them.

"Bonnie?"

She turns at her name to see Tyler staring at her, dressed in sweats and fleece sweater. He takes in her appearance with wide eyes, inhales a breath and his expression changes to a mixture of shock and disbelief. She must be soaked in Damon's scent, the smell of sex and sweat is probably pungent. He knows.

"Tyler…"

A part of her should say it's not what you think, but it is. She steps out of line and stands in front of him. "Tell me you're not sleeping with Damon. Tell me you're compelled."

"You know he can't do that to me."

Tyler shakes his head, dumbfounded, like he can't believe what he's being faced with. "Why…why are you sleeping with that asshole?"

"A lot of reasons."

"Is it…are you guys dating?"

"No. It's just sex."

"Why?" he asks again, "Bonnie, you hate the guy, we all do. Think of all the shit he's done, especially to you."

"I know," Bonnie's tone comes out sharper than expected, "Don't lecture me on how Damon's hurt me. I know what I'm doing. I know he's a monster. I haven't forgotten."

"I just don't understand why you're sleeping with him."

"You don't have to," her tone isn't defensive or gentle, just matter-of-fact, "I have my reasons."

"Does anyone else know?"

"No," she pauses, "but please don't tell them."

"Bonnie…"

She knows him and Caroline are stronger than ever, he's best friends with Matt and they'll tell Elena. She can't risk them knowing. She won't let the gates flood out and break them in the process.

"Please. Please, keep this a secret," Bonnie's words reek of desperation, her eyes sting with tears and her chest feels tight, "Please, Tyler, please, you can't tell anyone. Not Caroline, not Matt, no one. Please."

Tyler is silent, clearly conflicted but releases a sigh and relents. "Okay. I won't say anything for now. But please be careful, okay?"

Being cautious is the last thing on her mind, but she nods. "I will be. I promise."

"So?"

"What do you mean, so? Tyler knows," Bonnie crosses her arms, following after Damon as he traipses around the back courtyard, glass of bourbon in hand. There's nowhere else to sit since they've broken most of the furniture in the boardinghouse.

"I heard you the first time," he replies irritably, "What difference does it make? Are you gonna end this?"

"No. He said he wouldn't say anything, but - if he does, Elena will eventually find out. For all you know, that ends any chance you guys have of getting back together."

"She doesn't want to be with me," he spits out bitterly, setting down his drink, "and I can do what I want. She shouldn't care who I sleep with, even if it's her best friend."

Best friend is a pretty loose term for their relationship nowadays, Bonnie thinks, but doesn't voice it aloud. "That's exactly why she'll care."

Damon shrugs. "If Elena ends up pissed off and hurt, fine. She'll know how it feels."

"Is that why you're doing this?"

"Doing what?"

Bonnie blows out a frustrated breath, her arms crossed so stiffly they look like they might snap in pieces. "Having sex with me, dumbass. I know my reasons. What are yours?" A thought pops into her head, one she should've had sooner. "Are you even sleeping with anyone else?"

She wouldn't really care, he can't transmit STIs or get someone pregnant, but - she is curious. She thinks she would know if he was with anyone else.

"With all the energy you have, there is no one else," Damon smirks, "Who else would be so willing to spread their legs for me?"

Something blunt and hot forms in Bonnie's chest. Anger. "You're a dick."

"You would know," his expression turns devious, "your body sings for me, Bonnie, like no one else's has. You're so desperate to feel and I'm your solution, baby."

"Oh, fuck you," she's definitely getting pissed now, "you know what I think? You're so afraid to be alone that you've resorted to fucking the love of your life's best friend."

Damon's face darkens, and Bonnie feels a sick sort of pleasure that she's managed to hurt him, too. "Shut your mouth before I shut it for you."

"Do you know how fucked up someone has to be to do what you're doing?" she continues recklessly, drunk on vindication, "And you're risking it all, Damon, just to get a taste of my cunt. You just can't get what you want, can you? You never will, because you're a magnet for bad shit."

In a flash, Damon's behind her with his hand around her throat and the other cups her stomach. He blows a breath out that tickles her neck, making Bonnie's lashes flutter and his lips nibble her ear, his voice quiet. "You know the real reason why I fuck you? Because it tears you up, I can see it in your eyes every time. And when Elena finds out, we'll both be outcasts and you'll come running to me. I fuck you, because we're both miserable, and in the end, that won't change no matter what."

"You're despicable."

Damon's hand moves from her stomach to the button of her jeans, teasing her skin shamelessly and he sucks on Bonnie's neck, making her moan and tilt her head sideways to give him more access. His other hand releases her throat, sliding underneath her shirt and he palms her breast. "And yet here you are. Probably already wet for me."

She raises a brow, because she has a pretty good idea of what's poking her abdomen right now and she rubs against him tantalizingly. "Don't act like you have the upper hand."

He groans, sounding almost frustrated and he moves his hands to her hips, using his speed to get her against the wall, bricks tumbling out of place. He does not hold her gently, like she is fragile or made of glass, but rather as if she is made of thorns and cutting edges, something dangerous that will make him bleed. He kisses Bonnie harshly, biting and nibbling on her lips as she slips her hand down his pants, fondling his balls lightly. "Don't think this will ever mean anything."

"I know it won't."

Oof, it's been awhile. Admittedly, I'd kind of departed from the TVD fandom but then I got hit with inspiration and came up with this. May be continued; reviews are appreciated!
