So, here's the full on threesome smut! Which quickly devolves into a tiny bit of Season 6 plot…so… And a bookend of biting and Angry!Dean. And a longer than usual chapter!

Note on the D/s stuff: I'm not gonna claim this is healthy at all. Isabel's got issues and Sam's got issues. Isabel is severely scarred from her father's murder, not to mention hearing voices in her head her whole life. They all need therapy, lots of therapy, but all they've just got one another for the time being. As seen in the show, however, Sam's naturally very sexually dominating, Dean is not. A lot of this chapter is Dean trying to figure it all out and more through his point of view.

Note on the anal sex: Superhuman DNA, that's the whole reason they didn't need to spend a whole lot more time prepping Isabel. In other words, don't think that double penetration is that easy to do in real life. Fantasy, people, fantasy.

Anyway, please be kind! Writing sex scenes is pretty new and unfamiliar territory for me!

"Are you fucking crazy?" Dean yelled, pulling the sleeves of her tattered shirt up. "Did he bite you?"

"No, he didn't." Isabel replied, voice wobbling.

Dean wasn't satisfied by her answer. "You could have been bitten, Isabel. We were fine, we told you to stay put." He examined a cut on her arm, apparently the source of all the fresh red blood. It was already sealing shut. He continued to grumble, looking her over thoroughly.

"Dean, you need to stop." Sam said firmly.

Dean looked to his brother, "What?"

"You're scaring her."

Dean instantly loosened his grip on her arms. He looked at her face and wished he hadn't. She was totally still, eyes wide and fixed on some point far beyond them, her mouth was open slightly, her chin trembling as she pulled in quick ragged breaths, "Shit, Iz, I'm sorry."

She looked close to tears and didn't respond.

"Isabel." Sam said firmly, putting a hand under her trembling chin, "Are you alright?"

She slowly shook her head, pressing against Dean, her fingers white against the plaid fabric of his shirt. "No."

"What do you need?" Sam asked, rubbing his thumb in circles on her cheek.

Isabel took in a harsh breath at his question, releasing her hold on Dean like he had burned her, stepping back and letting her hands fall to her sides. Whispering, "Master", Isabel sank to her knees, staring up at him, waiting for him to give her what she needed.

Sam tried to quell the excitement that stirred in him at her whispered word, he really did, but that small, fragile voice never failed to send his dick into overdrive. He needed this just as much as she did. When her emotions got too out of hand, she'd shut down, and only one of their scenes could bring her out of it. Of course, they didn't have all of the items they'd enjoyed back in her house, and the items they did have were still in the back of the Impala, but they did have her collar. When Sam slid it around her throat and buckled it snuggly against her skin, she visibly relaxed into the role, tension fleeing her limbs, her eyes fluttering closed. "I'll take care of you." He murmured against her skin, kissing the back of her neck just above the silver buckle, letting her blonde hair tumble back down to her shoulders. "Strip."

It wasn't about trying to be sexy, so she pulled off her clothes in a rush with visible excitement, handing her already wet underwear to Sam, who praised her softly, examining her bare body to make sure she wasn't hurt anymore than the small cut on her arm that was already healing. She folded her torn clothes as neatly as she could before returning to her submissive pose on the ground.

He could hear Dean settling into the chair across the room, and when he glanced at his older brother, he didn't see the contempt he'd expected to. Dean's eyes looked heated, and he was leaned forward in the chair, watching them with rapt attention and a glaze of confusion. Sam fingered the collar, "You look so beautiful in this." Isabel trembled in response, knowing that with the collar on, she wasn't allowed to speak unless he told her to. That brought a grin to Sam's face, and he brushed her hair gently out of her face, "Good girl." The corners of her lips twitched up infinitesimally, and Sam laughed, watching the shock fade from her eyes ever so slightly, "There you are." He kissed her gently, his lips hovering over hers afterwards, exulting in the fact that she was alive and not a new member of the undead. "You scared us today."

"I'm sorry." Isabel whispered.

Sam startled Dean, surging forward and slapping Isabel's ass. She gasped, and Sam fisted a hand in her hair, "You weren't given permission to speak, Isabel. Mind your manners or you won't get to come tonight. Count out your punishment." Isabel obediently draped herself over his lap.

Dean winced at the noise that was produced when Sam's hand landed on her ass again. He became very aware that the first swat had just been a warning. This was Isabel's punishment. Within the first ten spanks, Isabel's ass was bright red, and Sam's mouth was set into a grim line.

Sam knew when the tears started to roll down Isabel's face, and hated it just a little bit, but knew that she needed her emotions worked out like that. He also knew that punishing her like this was the only way he'd be able to keep himself from continuing to be angry at her for getting in over head when they'd told her what she had to do to stay safe. He glanced back at Dean, who looked uneasy but intrigued, and kept his eyes on his brother as he moved Isabel from her crouch across his lap to rest against his chest while she pulled herself together. He kissed her temple, "You did beautifully, Isabel. I'm proud of don't you go greet Dean? You really upset him. Let's see if you can be a good girl now."

Dean watched the fire roar to life in Isabel's eyes at the challenge. He'd been under the assumption that it was fear that drove Isabel to his brother like this, but it wasn't. She truly enjoyed it, she enjoyed the challenge of following Sam, enjoyed pleasing him. She crawled towards Dean like a cat, her hips swaying just enough to tantalize him. Dean hardly noticed that he was reaching out to touch her until his hand cupped her cheek.

She grinned, and pulled herself up with his knees a bit before settling between his legs. She had his cock out of his pants before he'd even realized her fingers had been on his belt buckle. He'd been mostly asleep the last time she'd given him a blow job, only a day before that seemed so long ago, but how could he have forgotten how amazing it was to be in her mouth? He lost himself in her. Isabel stared up at him as she worked his cock with her mouth, her fingers gently teasing his balls. Dean stared back at her, "Careful, baby girl. I won't last very long if you keep doing that."

There was a smirk visible in her eyes for a second before she started sucking his cock. Dean threw his head back, and as he did so, caught a good look at Sam. His younger brother was sitting on the bed, his own cock in hand, watching every move Isabel made with rapt attention. He almost came then, but Isabel pulled back abruptly, looking to Sam. He gave her a nod, and breathed out, "Keep going, Isabel. Good girl. You can finish him off."

She returned to Dean with vigor, hollowing out her cheeks and sucking so hard he was sure his brain was being sucked out of his dick. When he came with a loud moan, she swallowed as much as she could, but the sight of her with his come dripping out of the side of her mouth nearly made him hard again. He'd need a little bit more time to catch his breath though. His eyes trailed back across the room to his brother.

Sam had come too, all over his hand and stomach, more than likely ruining the pants he'd carelessly left bunched around his thighs. "Isabel, did you like that?" He asked, panting with the effort to bring himself back under control.

When she nodded vigorously, Dean became aware that Isabel had moved to rest her head on the inside of his thigh, and her warm breath tickled his skin. He looked down. While she was wrapped around him, his leg wedged between her breasts, her eyes were on Sam.

Sam was smiling, the kind he usually reserved for their brotherly bonding moments, the one that said he was completely content. Dean wasn't even phased by watching his brother walk across the room to them, his own come dripping down his skin. Sam had wiped his hands off though, by the time his lopping walk has gotten him to them. He knelt beside Dean, right in front of Isabel and cupped her cheek with one of his big hands, not looking perturbed at all when he wiped his own brother's semen off her chin, "I'm proud of you, Isabel. You scared the crap out of us, but you did good." He glanced up at Dean as he touched the latch at Isabel's neck, "I think we're done, but only if you're calm." She flinched away from his hand at her collar, pressing herself closer to Dean, and glaring at his brother. Sam sighed, "Alright, Izzy. You can keep it on because you were so good, but we're done with the scene."

Isabel sighed in satisfaction, "I want a bath."

"Let's go." Dean chuckled, that was the Isabel he was used to seeing, the argumentative clumsy one who apparently was handy with an angel blade. Dean scooped her up, delighting in the giggle she let out, throwing her arms around his neck and burying her face against him. Sam had sat back on his heels, and was pouting in their direction.

Dean felt Isabel shift, "You too, Sam."

Sam's puppy-dog smile made Dean feel better. When Sam had been spanking Isabel, he'd seen something in his brother's face he hadn't seen since Lucifer had been in his brother's body. For a minute, he'd been terrified.

With his brother's massive size, the tiny tub was going to be a close fit, but he didn't really mind, and Isabel seemed thrilled. And Dean definitely couldn't complain when she started kissing him as soon as all his clothes were off, her intentions obvious. "Do you know how hot you are when you come?" Isabel asked between kisses.

Dean moaned, "Do you know how sexy you are?"

She grinned, "I might have an idea." He couldn't resist her any longer, and Sam had given up his control over her, so Dean put his hands on the globes of her ass and pulled her up. Isabel winced a little at his grip, but once her ankles were locked around his waist and his hands moved to her hips, she was better. He had his cock in her tight heat seconds after, rocking her hips slowly against him, making them both shiver.

Sam rolled his eyes, "You two want to get in the tub? The water's warm now."

Dean just walked with her to the tub, his thighs straining as he lowered them both into the water. Isabel braced her left hand for impact and put her right on the back of Dean's head as, in the last inches, he slipped. Dean ended up with a sore ass, but it was worth it when Isabel nearly smothered him with her breasts, laughing at him, her hand locked in his short hair.

Sam was laughing too as he slid in opposite Dean, his legs framing his brother's body. Isabel moved up and down over Dean's cock, making some of the most obscene noises he'd ever heard. Watching the muscles in her back work was all it took for Sam to get hard again. He sat forward a little, running the flat of his tongue up her spine and wishing he could be in his brother's place.

Isabel seemed to sense it, looking back over her shoulder at him, groaning out his name, "Sam...I need you."

He raised an eyebrow at her, his hand stilling on his dick, "You sure?" Her sex-glazed glare was all he needed to see as encouragement, maneuvering himself so that he was almost spooned behind her. They'd fooled around with anal sex a few times before, but never with anything even close to the size of Dean's cock in her pussy, so Sam wasn't going to just take her like an animal.

He worked her open slowly, working his long fingers into her and peppering kisses on her shoulder blades as Dean slowed down to an agonizingly slow pace in order to stave off their releases. Sam put an arm between Isabel and Dean, tilting her hips a little bit more to make it easier on her. Isabel liked pain as much as the next submissive, but she wasn't a masochist, and they weren't in a scene. Sam wasn't about to allow himself to hurt her.

He needed to prove to Dean that his relationship with Isabel wasn't about pain.

Isabel put her hand over his, linking their fingers and pressing his palm into the soft flesh of her stomach. "I'm ready, please, Sam." She growled in frustration, sounding close to tears.

Sam obeyed, slowly easing his large girth into her. His hips jerked forward unwittingly when he felt Dean through Isabel's walls, causing her to whine in surprise and a bit of pain. Sam cursed and went to pull out, but Isabel wouldn't have it. She dug her fingernails into the back of his hand. "You...pull out now, and I...won't even look at you for a week." She turned her head to the side to look at him. "Go, Sam. I'm okay."

He kissed her, sheathing himself in her fully and reveled in her shudder of pleasure. Dean moaned, his hands tight on her hips, "So...tight. Damn." Dean gave an experimental thrust and all three cursed, Isabel throwing her head back to rest on Sam's shoulder as she panted with the overwhelming sensations.

While they moved in her, Sam rubbed her clit to keep the pleasure she was feeling from being overwhelmed by the pain, and Dean spent a significant amount of time sucking on her nipples. The odd thought passed through Sam's addled brain telling him to remember to show Dean the nipple clamps he and Isabel were so fond of.

Isabel was first to come, going completely rigid an instant before she trembled in pleasure rather than fear. Dean shuddered his release inside of her once her internal muscles started spasming, and Sam last, biting the side of Isabel's neck when her crafty little hand snuck down to fondle his balls, rubbing the soft skin gently. Sam stayed inside of her as he came, licking languidly at the red marks he'd left on her neck, not noticing the blood that oozed from her skin.

Dean pulled out of her first, grabbing a wash cloth from the side of the tub and wiping her up as best he could with his brother still buried inside of her. When Sam finally pulled out, Isabel whined and fell forward against Dean like a puppet whose strings had been cut, "Woah, baby girl, I've got you." Dean wiped a stubborn spot of blood off her cheek, trying to ignore the sly, satisfied grin she was giving him.

After a few minutes, Sam stood up, water dripping down his muscled body. He had a soft smile on his face, bending to brush Isabel's hair out of her eyes, "Want to get out?"

Isabel nuzzled Dean's chest, "I'm cold."

The Winchester's laughed, and Dean put his arms around her, squeezing as he joked, "That's cause the motel water heater's not good enough to handle us."

Isabel cursed under her breath and stood slowly on shaky legs, bowed out ever so slightly like Dean's, letting Sam wrap her in a towel before scooping her up. She was asleep before he got her into bed, tucking her thin body into the covers. Sam glanced back at Dean warily.

Dean wasn't looking at him though, his eyes were solely focused on Isabel, "We're lucky bastards, aren't we?" Dean said softly, sauntering to stand next to Sam.

"We aren't going to talk about what just happened?" Sam said speculatively.

Dean plastered on a fake grin, "No, no we aren't. All for her, Sammy."

Sam nodded, "Right."

A few hours after being awoken to Sam pushing himself into her while Dean kept on sleeping, Isabel woke up for the day slowly, curled blissfully between the two Winchester's. She ached, but didn't really hurt. The adrenaline had worn off, and she thought over the night before with new eyes. She'd lost control. Vaguely, she wondered how freaked out Dean must have been. Her intentions had always been to ease him into the lifestyle she and Sam shared, and to let him choose what his roll in it was going to be. She'd taken that opportunity away from him. Because she was too weak to handle herself.

She heard her phone ring, and pulled herself out of bed, gently pushing Dean's grabby hands off her, "Hello?" She whispered into the phone, having moved into the bathroom to let the boys sleep longer.

"Isabel, precious, where are you?" Her mother's voice said urgently.

"New Orleans, why? What's wrong?" Isabel said, rubbing sleep from her eyes.

Veronica made a garbled noise of stress, "It's my sister, she got out."

"You have a sister?"

"Yes, Isabel, focus!" Veronica snapped. "She's been locked in Purgatory since we were teenagers, but someone let her out."

"I didn't know you had a sister." Isabel said, looking at herself in the mirror. The boys would both be pissed if they saw how her body looked in the morning light. She was covered in handprint bruises, bites, and hickeys, all in the midst of healing.

"Isabel, that is so not the point." Veronica whined, "Eve is what most would call my evil twin. She's completely insane and insanely powerful."

"Don't see how that makes you two any different." Isabel muttered, rustling through her bag for clothes that would cover the majority of the marks until they faded away completely in a few hours. She'd take a shower, but poor Ion needed to go outside first.

Veronica hissed like a cat, "Not the time for snide remarks, Isabel. She calls herself the Mother of All, and, partly, she is. Eve is the Mother of All Monsters, and now she's loose on Earth again. You and the boys have to stop her."

"Why can't you? We're busy." Isabel said, staring at her neck in the mirror where a perfect impression of Sam's teeth rested, the skin angry and red, some parts still bleeding. She looked like an extra from the beginning of a zombie movie.

"I don't care that you three are humping like rabbits, I really don't, but that's no reason for you to be rude." Veronica said, voice sharp, "I'm busy with other things."

"So you're terrified about this lady, but you're just going to send us after her?" Isabel tried to reason, pulling on black yoga pants because they were the only way she'd be comfortable enough to not walk around bow legged like Dean all day.

"Oh, you three are smart, you'll be fine. Trust me, you'd rather I kept my paws out of it. Eve's really quite maternal, but she down right hates me." Veronica explained.

Isabel sighed into the phone, "Okay, where do we start?"

"Sandusky, Ohio. But please, be careful. You'll probably piss her off." Veronica warned.

"Great, the aunt I never knew about is going to hate me. You know what, I'm getting real tired of all this fucked up family shit. Thanksgiving is going to be great this year, isn't it?" Isabel joked sarcastically, but heard her mother's side of the line click off. "Fine, witch."

"Who was that?" Sam asked from the doorway of the bathroom.

Isabel ruffled her hair, making it fall over the bite wound on the side of her neck, "My mother, she's got a hunt for us."

"Oh really?" Sam chuckled.

Isabel nodded, "Yeah, my aunt, Eve, the Mother of All Monsters, or something like that."

Sam furrowed his eyebrows, "Eve, like Bible Eve?"

She shrugged, "Don't think so. My mom way predates humans, and she said they're twins."

"Sounds like it's right up our alley. Did she give a hint as to where we'll find this Eve?" He asked, putting boxers on and drawing a pair of jeans up his long legs.

"Sandusky, Ohio." Isabel told him before leaving the room, grabbing Ion's leash, and taking the dog outside.

Isabel sat on a beat up curb bumper and let Ion run, taking into account every ache and pain in her body. Her ass hurt from Sam's spanking, but the pain dulled more and more with every beat of her heart. Her shoulders ached from having locked them in place so long to brace herself against the bathtub. Really, she needed a shower. Thanks to Sam's early morning wake up, she was sticky in places she didn't really need to stay sticky in, and her neck was killing her.

Usually when Sam bit her it healed by morning, but something had changed. Her neck wasn't healing any faster than usual, but the bruise she'd been watching on her arm was already gone. Isabel picked up a piece of glass off the ground from a long destroyed beer bottle, and pressed the sharp edge into the palm of her hand. Blood welled up, but by the time she'd tossed the bloodied glass away, the skin was pink and whole. "Weird." Isabel buried her face in her hands. Ion nudged his nose against her hands, and she put her arms around his neck, "Hey, buddy."

He pulled away and lay down across her feet with a petulant whine, and Isabel sensed Dean coming up behind her before he said a word, "Baby girl, Sammy says we're on the hunt again?"

She nodded slowly, "Yeah, my mom called and rambled some shit, wants us to research." Isabel flashed him a bright smile she didn't feel and held her hand out to him, "Let's hit it."

Dean pulled her to her feet, and Ion scrambled to his, shooting the older Winchester a nasty glare. Dean watched Isabel walk a few steps, "You okay?"

She gave him a genuine smile, and kissed him, "I'm fine. Promise, a shower and I'll be good to go."

Isabel started to walk back to the motel room, but Dean grabbed her by the elbow, "Wait. I-" He trailed off, and looked away from her questioning gaze. "I hope I didn't hurt you last night."

Isabel shrugged, "You didn't, Dean. Not in anyway I didn't need or fully enjoy. Trust me." She wriggled her eyebrows at him, "Maybe next time we put a non-slip mat in the bottom of the tub though."

Dean chuckled, rubbing the back of his head as she tucked herself under his arm. "Yeah, my ass hurts."

Isabel giggled, kissing him again, "Not as much as mine, I'm sure."

"You are probably right!" He said, laughing as they walked to the doorway leaning on each other. Isabel pulled away to catch the leash Ion was dragging behind him and Dean went totally still. The instant she heard his angry intake of breath she knew what he was going to say, knew what he'd seen, "Isabel, what the hell is that?"


Closer: Tegan & Sara

"All I want to get is
A little bit closer
All I want to know is
Can you come a little closer?

Here comes the breath before we get
A little bit closer
Here comes the rush before we touch
Come a little closer

The doors are open
The wind is really blowing
The night sky is changing overhead

It's not just all physical
I'm the type who won't get oh so critical
So lets make things physical"


Well…hope I didn't just scare a bunch of people away! Next chapter is already half written! As always, comments and suggestions are more than welcome!
