Dean gets another spontaneous tattoo, Isabel gets a little handsy during nap time, and Sam's just having a great time keeping them both from getting themselves killed!

Enjoy!

The Lightning Strike (What If This Storm Ends?): Snow Patrol

Dean was having a really hard time getting in line with Isabel's ferocious mood swings. One minute she was herself, and the next she was a raging bitch, snapping at him and Sam like they were lunch meat. Her current mood was flirty. They were driving full tilt to take out a vampire nest in New Orleans while Bobby took the one closer to home, and Dean was supposed to be napping while Sam drove. It was pretty damned hard with Isabel carding her fingers through his hair and asking him to take his clothes off, "I want to see it."

"What?" Dean choked out, jerking up.

Isabel smiled, so innocent and demure that he almost fell for it, "Your tattoo. I've glimpsed it before, but never gotten to take a good look at it."

Sam glanced over his shoulder, saying sternly, "Isabel..."

She pursed her lips, pouting, "I just want to look. Besides, it's on his back. Jeez, I'm not asking him to take his pants off in the car when I'm currently a no fly zone."

Sam scoffed, "We both know that's never stopped you."

"Oh, shut it." She snapped half heartedly before returning to fiddle with the hem of Dean's shirt. "Come on, you can go to sleep after."

Dean groaned and lifted his shirt. Isabel kissed his anti-possession tattoo before he turned over, facing the window. She traced the Enochian tattoo with the tip of her finger, "I can never get over how lovely Enochian is."

Dean grunted, "It's all gibberish to the rest of us."

"Perk of being a nephilim, I guess." She whispered, seemingly entranced by the tattoo.

Suddenly, Dean hissed, jerking away from her touch, "Ouch!"

"What?" Sam asked from the front seat, trying to see the pair in the rearview mirror in order to try to keep his eyes on the road.

"It's fucking burning!" Dean hissed, twisting in an effort to see the mark on his back.

Isabel kept trying to get him to hold still so she could look too, and finally resorted to grabbing his package through his pants. "Hold still!" She yelled, accentuating her words with a not so gentle squeeze.

Dean froze, hardening in her hand despite the stinging in his back. They must have been a sight, Dean half on the floorboard in the Impala with Isabel behind him. All they needed was a strap on and it would have been a porno. "What is it?" Dean finally croaked as Sam pulled the car off into a wooded area and threw it into park.

Isabel was quiet, tracing her hand over him again, but now her touch soothed the burn. "I'm not sure. There's something new. I can't read it, it's like it's blurred."

Sam peered over her shoulder, "That's freaky."

"Am I gonna die? Is some hoodoo tattoo going to kill me?" Dean asked, half hysterical, and very, very pissed. Mildly turned on too, if he had to admit it, but just because of Isabel's hand.

"Relax, Dean, it's clearing up." Sam said, placing one of his hands on Dean's back to move the mark into better light. "Can you read it?" Sam asked Isabel, putting a hand on her shoulder.

"Almost." Isabel whispered, moving her hand up to rest on Dean's abs, holding him still. Finally the black ring settled enough that she could make out the letters encircling the one that marked him as Faith. "Got it." Isabel told them before relaying the message, "Faith is greatest when expressed through love."

The instant she read the words, the burning in Dean's back stopped. Breathing through the stress from the pain, Dean asked, "What the hell is that supposed to mean?"

"Not a clue." Isabel said, rubbing his back comfortingly, "You okay?"

Dean rested his forehead against the Impala's leather seat, "Don't really appreciate being used as a cosmic Etch-e-sketch."

"I didn't ask if you were happy, I asked if you were okay." Isabel groused, rolling him over so he could lay across the seats, Sam moving to accommodate his legs on the seat.

Dean's eyes were closed, "I've got a killer migraine now."

Isabel and Sam shared a long look before Isabel maneuvered her way under Dean, resting his head in her lap and placing a hand on either side of his head, "Rest, Dean."

He was asleep in less than thirty seconds, and Sam slid into the front seat, "What was that?"

"I have no idea." Isabel answered.

"I do." He said slowly, "I don't understand it, but...it's got something to do with a verse in the Bible."

"I wouldn't know." Isabel told him, carding her fingers through Dean's short hair. "Mom never had us read the Bible. Of course that's odd now. An angel that isn't obsessed with the word of God. Although now, I suppose she's his disgruntled ex-wife, so I don't blame her for not forcing it all on the two of us." She sighed, "I mean me."

"How's Dean?" Sam asked half an hour later, rubbing between Ion's eyes, the dog having inched closer and closer, his head now on Sam's thigh, sound asleep.

Isabel kissed Dean's forehead, "I think he's fine, that just took a lot out of him." Her eyes travelled down his body, "How the hell are you two both so attractive?"

Sam chuckled, "Our dad was nice looking, I guess."

"What about your mom?" She asked, tracing around Dean's anti-possession tattoo, pressing her thighs together at the delight in being in complete control of such a strong man.

"I don't remember her, but we've done some time travel, so I saw her once." Sam said thickly. "She was very pretty, a lot like you actually, fragile looking and blonde. Dean and I mostly look like Dad."

Isabel ran a finger over Dean's full lips, "I wouldn't say that. You and Dean are both pretty."

"Isabel." Sam said warningly, knowing exactly where her mind was headed.

"Keep driving." Isabel requested, flicking the buckle on Dean's belt open. She wanted to see the stress completely melt away from his face. She hated what she'd brought into their lives. Some crazy tattoo being burned into his skin? It was awful. While full on sex might have been off the table for a few hours more, Sam was right, Isabel wasn't one to shy away from oral, especially since at the moment, that was all she could give to them. She'd kill for a shower.

"If we get pulled over, you're paying all the fines." Sam told her, adjusting the rearview mirror so he could watch.

"Don't get pulled over." She said, unbuckling and sliding out from under Dean, putting his head on the pillow she'd taken to keeping in the back at all times. Isabel kneeled on the floorboard, taking a hold of Dean's jeans and pulling them down slowly, pausing every time he made a noise like he was about to wake up. Ten, desperate minutes later, and his jeans were in a puddle on the floorboard and Isabel kneeling between his spread thighs.

Sam watched every move, amazed that Dean was sleeping through it all, but Isabel was being so careful, so gentle, her face carrying a soft smile the whole time. She scraped her nails across Dean's chest, his nipples tightening, cock hardening slightly.

Isabel got comfortable, leaning down, licking her lips as she grasped him gently. She licked the tip, tasting the saltiness of his pre-come on her tongue. The heat coming off him made her burn. He was making little breathy sounds at her touch, and Isabel figured he'd only be asleep for a few minutes longer. She used her free hand to brush the pad of her thumb over his nipple again, then pinched it at the same time that she took the head of his cock into her mouth. Isabel had to stop for a few seconds, too overwhelmed to suck on him and remember to breathe at the same time.

Sam chuckled knowingly from the drivers seat, adjusting himself in his pants.

Isabel glared, slamming a palm against Sam's head rest, knocking his head forward, "Damnit, Isabel." He hissed, rubbing the back of his head, glaring back at her through the rearview mirror.

She hushed him with a finger against her reddened lips before lowering herself back to Dean.

Since he was still asleep, she took her time, tracing every vein on his cock with her tongue, and sucking a bright red mark into the crook of his leg. He jerked awake just a few seconds before he came, spilling down her throat with a guttural yell. "Son of a bitch!"

Gasping, Dean locked his green eyes on Isabel, fists clenched on the leather seats. Isabel grinned, wiping semen off her chin and licking more off her lips, the very picture of debauchery as she said, "Rise and shine!"

Sam chuckled, "Forgot to warn you, she's got a bit of an oral fixation."

"A bit?" Dean chocked out as Isabel cleaned his spent cock with her tongue.

She handed his underwear back to him, a satisfied smile on her face, "I'm a complicated gal, and you just looked far too tempting for me to resist."

After pulling his underwear on, Dean rubbed his hands over his face, stubble scratching at his palms, "You two are going to kill me."

"Oh, Dean, just a little death, promise." Isabel promised, laying across the seat and forcing him to his side so they could spoon.

Dean wrapped his arms around her, pulling her body flush to his and kissing the back of her neck, "Just for that, we start training when we get to Louisiana."

Isabel groaned, "Yay. Can we at least visit the French Quarter before you start kicking my ass?"

Sam shrugged, "We need to start staking the place out as soon as possible."

"Oh, come on, Sam. I can do that without being babysat by you two. I took a break from hunting, I didn't forget how." Dean grumbled.

Isabel sighed happily, "That's settled, perfect. I've never really had much of a chance to travel before."

The brothers both started laughing, and Dean kissed the back of her neck again, "Well, get used to it now, baby girl. We never stay one place for too long. Too many people need us to help save their sorry asses."

"I know." She said quietly, and was asleep for the rest of the drive.

"I should wake her how she woke me, shouldn't I?" Dean said to his brother once they parked.

"Nah, Isabel gets horny as hell when she's on her period, but try to go anywhere below her belt and she turns into a rabid little karate ninja." Sam warned severely. "Women."

"Women." Dean agreed, resorting to his favorite method of waking Sam up. The Wet Willy.

"Holy shit!" Isabel screamed, practically jumping out of the door Sam was holding open. The brothers were laughing hysterically as Dean climbed out after her. "So not funny!" She growled, rubbing furiously at her ear, "Nasty!"

Dean had a half second to react before she started chasing him.

Sam sighed, a smile on his face as he went into the motel's lobby to get a room. Dean and Isabel joined a few minutes later, both red faced and laughing, "Damn, Sammy, she's fast."

Isabel giggled from her spot on Dean's back, arms loose around his neck, "He forgot, I grew up with a big brother too. Angel or not, Danny terrorized me like any other big brother would have."

"Glad you two are wired." Sam muttered before turning back to the motel manager, "I think they had too much candy on the ride here."

"You said just one room?" The woman repeated for what had to have been the third time, still stuck in a cycle of disbelief.

Sam winced, "Yeah, just one." The woman practically threw the key at him. Walking out with the other two, he shook his head, "I said two beds."

"Some people just can't handle it when kinky folks like us pop up." Isabel said, hopping off Dean's back to let Ion out of the Impala, "Of course, she probably thinks you two are gay. Wonder what she thinks of me?" She added idly, whistling to Ion when he strayed too far in the parking lot.

Sam slid behind her, "Probably not that you're the wanton little cock slut you are."

Isabel chuckled. His voice was dark, but the gentle way he held her let her know that his words were just meant in jest, not that he was going to whip her collar out and take her on the hood of the Impala, "Very funny, mister. And here I am on the last legs of my monthly visitor! Sucks for you!" She ducked out of his arms, grabbing her bag from Dean, "I'm going to shower, change clothes, and then you promised to take me out to see the sights. So that's what we're going to do!"

"Hey, that was Dean that made that plan, not me. I'm exhausted." Sam sighed, throwing his bag on the first queen sized bed.

"Jeez, if I stripped naked right here you wouldn't be so tired." Isabel said sarcastically.

"Come on, man, just take the girl out. You'd never be any good use on a stake out alone if you're falling asleep. I'm sure Izzy can keep you entertained." Dean said, holding a bottle of dark red liquid up in Isabel's direction, "Deadman's blood, poison to vamps, got it?"

"I know, Dean, you told me when you guys went and got it." Isabel said snidely, going into the bathroom.

"Teacher's pet. She's a teacher's pet. I'm surrounded by teacher's pets." Dean said ten minutes later, aghast at the realization.

"Seriously, Dean? Not everyone needs to be told the same thing fifteen times for it to stick." Sam said, grinning at his older brother as the older man pulled a face at him.

"Now, now, boys, no fighting." Isabel said, coming out dressed in shorts, an ACDC t-shirt from Dean's bag over a white long sleeved shirt, and her favorite Converse. She knelt next to her dog, who licked her face lovingly, "I know, you're my good boy, you'd never do anything wrong." She stood up again, ruffling the gold hair on top of the dog's head as she grabbed Sam's arm. "Come on, Sammy, let's go!"

"Text me if you find anything." Sam ordered his brother as he was dragged out of the room by Isabel, her wet blonde locks bouncing behind her.

Dean gazed at the dog, "Guess it's just you and me, bud. Let's go find some vamps." He got suited up and headed out, glad they were close enough to the tourist parts of town that Isabel and Sam had left Baby for him. Grudgingly, he let Ion sit in the front seat again. "No drool, bud. Drool, and I'll figure out how to make myself some fur boots." The dog whined in response, but laid down, paw touching Dean's leg, "Suck up, just like your Momma, eh?" Ion whined again, "Okay, I get it, let's go kick some ass. Hopefully vampires can't give Krypto the super-dog suped up parvo. That happens, and, bud, you're on your own." He stared up at the red light he was stopped in front of, "Shit, I'm talking to a dog."

Already halfway into town, Isabel was having a blast, and even Sam was starting to loosen up. "Smile!" Isabel cooed, pressing her cheek to his and snapping a picture with her phone.

"You're enjoying this way too much." Sam told her, but the smile on his face seemed to like being there, especially when she wrapped her arms around his waist and looked up at him, that same love glowing in her eyes.

"Of course I am. I'm with you in an amazing city I never could have dreamed of seeing." She told him, and they kissed languidly for a few minutes under the bright lights of the city. "How are you feeling about earlier?" She finally asked as they were walking through the Quarter.

"You mean when you gave Dean a blow job while he was asleep and I was driving?" Sam said haughtily.

Isabel nodded, "Were you mad?"

"Shit, Izzy, how could I be mad? A little jealous, sure, but..." He caught the look on her face and groaned defensively, "I said a little!" She pursed her lips, and he brushed her hair out of her face, "Would it be sick for me to say I could have watched you do that all day?"

A faint blush colored Isabel's face, and she shook her head, "Not any sicker than the fact that I dream about a whole slew of other depraved things."

They started walking again, and Sam asked, "You really think he'd be okay with watching me color your ass bright red."

Isabel chuckled, "He'd probably give me a few whacks of his own. I'm not worried. He'll come around when he's ready. Not like he doesn't already know we're freaks in the bedroom."

"Or car." Sam said wryly, wanting to see her smile. She dissolved into giggles, the smile he was looking for brightening his whole mood, but she suddenly stopped, hands on his chest. "What is it?"

Isabel stood on tiptoe, pulling him into a hug, "I think we're being followed."

Sam jumped slightly in her arms, "What?" He held her tighter, and to anyone they looked like any other young couple stopped to make out amongst the sights of the Quarter. "Who?"

"Two shops back, dark hair." Isabel whispered against his ear.

Sam forced a smile, like she'd just told him something particularly naughty, as he scanned the crowd. "Shit, she knows who I am."

"Ex-girlfriend?" Isabel chirped.

Sam grimaced, "No, vampire-that-got-away."

"Perfect. Guess I won't be getting any more shopping done." Isabel said wryly, handing Sam his phone out of his back pocket, "See where Dean is."

"Whatever happens, you are staying in the car." Sam half growled at her as he dialed the number of the phone Dean was currently using.

They rendezvoused with Dean, who reiterated the order, looking between her and the dog with a firm, "Stay here.", as the boys went to war, storm clouds rolling in.

It only took five minutes for Isabel to get worried, and she found herself wandering into the abandoned club the vampires were nesting in. Not the smartest thing she'd ever done, but the instant she'd left the car, leaving Dean's ACDC shirt with Ion, her angel blade had appeared in her hand. Quite the handy thing, as it turned out. With it in her hand, the girl in her head was back, coaching her through how to fight the female vampire she encountered in the doorway, explaining just how to use the short blade to decapitate her. In a haze, Isabel drifted inside after killing the other female, bleeding from a scratch on her arm and covered in vampire blood. The urge to vomit was overwhelming.

The boys were outnumbered, but fine, and a bleeding Isabel served as a fantastic distraction. She killed one more before being pinned down by a male, much taller than Dean and wider than Sam. His teeth gnashed in the air next to her face, and only her half baked angel strength kept him at bay. Her heart had nearly hammered out of her chest until the vampire's head suddenly rolled away, a fresh cascade of blood covered her, and his body fell on top of her. Isabel trembled under the weight, not moving until Dean rolled the body off of her. Dean toweled the blood off her face and then they were in the motel room, Dean looking her over better in the light, the anger on his face scaring her more than the vampires had. It was too much. She couldn't breathe.

All at once, she felt herself disconnect.

Sam's firm voice pulled all the loose threads of herself a little closer, and when he touched her, all the pieces got thrown back together. Her mind was one raw, aching wound, but all she needed to soothe the ache was hearing Sam's voice and obeying every word. The rest of cognizance could come later, once she could finally breathe again.

The Lightning Strike (What If This Storm Ends?): Snow Patrol

"What if this storm ends?
And I don't see you
As you are now
Ever again

A perfect halo
Of gold hair and lightning
Sets you off against
The planet's last dance

Just for a minute
The silver forked sky
Lit you up like a star
That I will follow

Now it's found us
Like I have found you
I don't want to run
Just overwhelm me"

So Isabel's definitely got some PTSD issues, and the next chapter is about her coming out of her shell-shocked state...also, the next chapter is like 85% smut...okay, maybe even 95%. I'm almost done with it, and favorites and reviews always help me write faster!

Any guesses to what "Faith is greatest when expressed through love" means? Love to hear your theories!

A clue for the next chapter is the chapter song, 'Closer' by Tegan and Sara.

Thanks for reading!
