Night moves.

Sam rubbed his eyes, the computer in front of him blurred and he shook his head. It was definitely time for a break. Pushing up from the table, he paused to listen to the silence, no one was there, or at least no one was in the actual living space of the bunker.

Two people with car-fetishes could only be one place.

Under the iron staircase, Sam stepped into the small hallway that lead down towards the back of the garage, then up the seven steps to stop and watched the quiet happenings there, and Ali's ass in a pair of shorts. Strangely enough, they were cut off that Dean had worn one time himself but Ali's legs looked so much better in them, especially as she bent over the engine of the midnight blue mustang.

"You're doing that wrong." Dean said from somewhere else in the place, probably from under Baby.

Sam smiled as Ali stood, blowing up towards her hair to get it out of her eyes and moved around the side of the car, only to look down. Sam made a silent move across the floor to rest against the beam on the other side.

Ali was standing over Dean, leg on either side of his hip as he rolled out from under the car. He stopped, licked his lips and looked all the way up her bare legs before he gave a grin that told Sam everything he needed to know.

He was doing it on purpose.

"Tell me one more time, Winchester, that I'm doing anything wrong and I swear to God, I will end you!" She growled, but it was definitely playful.

Dean's hand came up and slapped her thigh.

"Go put on some music will ya, it's way too quiet in here."

Ali humphed and stepped over him towards the radio. She didn't care what she played but only if it pissed Dean off. Sam could only roll his eyes when "Slow hands" started to play and Dean was suddenly on his feet.

"Sam's going to kill you if he hears that song one more time."

But Ali was already swaying to it and Dean was completely entranced. In fact, the last statement he made had no guts behind it. Sam had to admit, he knew how his brother felt.

"Sam loves this song." Ali smiled, her hands going up through her hair as her hips moved.

"Christ, you move like that and he'd love anything."

Could this be it? Could they finally do this without him there, or without them knowing he was there? Sam slipped back a little into the shadows hoping he hadn't been seen yet and smiled as Ali turned back towards the cassettes that were on the counter. She grinned as she popped one in, her hips still moving seductively as Sam watched Dean's face.

His brother's green eyes were locked on the way she moved, and he did that thing where he licked his lip and bit down on his bottom one. Yep, Dean was all for it, and then the music started.

Ali turned with those few first beats and made her way over towards the car. She didn't say anything, just moved the rod and gently closed the hood. Dean rolled his eyes and though Sam was pretty sure it was an unconscious decision on his brother's part, Dean moved closer.

"Night moves, really?"

Ali slid up that hood, knowing that she wasn't wearing anything that could scratch it, and placed her feet solidly on the front bumper, bracing herself from falling off. Dean ran his hand over the paint, skirting along the edge of the car until he got to her bare legs.

Dean slid the tips of his fingers down over her knee, like he was tracing the outline of her as he moved to stand between them and suddenly, Sam could hear his voice. A low melodic sound that almost made him shiver.

Dean KNEW how to sing. And he was GOOD.

"I was a little too tall, could've used a few pounds. Tight pants, points hardly reknown. She was a black-haired beauty with big blue eyes, And points all her own sitting way up high. Way up firm and high." He was moving in, almost too slowly, and Sam's heart thumped in his chest.

Dean leaned down, Ali still hadn't moved, but her hands braced her back against that car, holding her up as Dean placed his own on each side of her, bringing his face, his lips, his breath, close enough that one word would have them locked together.

"Sammy…" Dean started, as his hand moved from the hood, up her arm to the base of her skull, where his hand moved up to tangle in her hair.

"Oh, I think Sam is just fine with this, Dean." She sighed.

Did she know he was there? Sam's breathing deepened, his own body knowing what needed to happen as he grew hard and strained against the jeans he wore, ones that he thought were loose and comfortable.

"How do you…?" he stated and Sam swallowed hard when she reached up and grabbed a handful of Dean's shirt.

"If you don't kiss me, Winchester…"

But she never got the last words out. Dean's mouth crashed down on hers hard and thorough, pulling a moan from deep inside her as she pushed up and used her other hand to slide across his neck.

From where Sam was, the scene was just as intense. Dean wrapped an arm around her waist, the one in her hair tightening as she arched her body up to touch him and her leg wrapped around his hip to draw him in.

The kiss deepened to something needy and heated, and when Dean backed away, just for a breath, Ali went for his shirt, grabbing the hem of the black fabric to pull it over his head. Sam hadn't seen his brother's back for a while, at least not in a way that would let him see the old scars there.

Sam knew each one, every slice that he had sewn up himself, but to see the way they lined his tan skin and the gentle way Ali's small fingers immediately found them, traced them, it made Sam shiver and wonder how his looked. Cas had healed enough but never took them all way.

Dean growled, a deep, possessive sound that had Sam instantly back on their faces as the older one moved from her lips to her neck. Apparently, tracing them was something that turned him on and Ali was doing everything right.

Ali's shirt came off next as Dean lavished her neck and breast with tiny kisses and little nips, bringing out the quiet whimpers she made whenever he started his attentions on her body. They would get louder, of that Sam had no doubt, but it always started out soft.

Her hands were in his hair as Sam caught the movement of her bra slowly lowering, exposing her taut peeks to Dean's mouth and she suddenly let go, quickly placing her hands on the car as she pushed them up to his wet mouth.

Jesus, Sam was so damn hard, he could have gone right then, but as it was, he was enjoying the scene too much. With a shaky hand, he did his best to unzip his jeans quietly and finally, he was free, his large hand grasping his own cock. FUCK! Watching her did amazing things to him. And yes, Sam was a freak!

When she was better in control of herself, Ali quickly sat up, grasp for the button on Dean's jeans and Sam listened to him chuckle.

"Impatient, aren't you?" Dean's voice was deep and full of lust, and Sam saw Ali shiver.

"Take them off, Dean," she begged… BEGGED! And there had only been a few times when she did so.

"No," Sam stopped his own strokes, unsure of what he had heard as Ali sat back just a bit to stare into Dean's eyes. "If we're going to do this, we're going to do it my way."

"You're such a control freak!" Ali growled.

"You wanna argue this now?" But his lips went back to her skin.

"I need to touch you, Dean, I need you to touch me, this is driving me fucking crazy."

"You need to learn some self-control."

"Ugh!" She cried, nearly in tears under the way his hands moved softly over her. "Please, Dean, need you so much."

"Shh, baby, let me take care of you." Dean was tender, nothing he said had any snap behind it but Ali's eyes were closed, her lips parted and her hand moved back to his hair as Dean moved, at a snail's pace, lower down to her stomach.

Again, Ali whimpered and Sam knew just how she was feeling. Ali had never taken anything slow, or soft. It was always hard, fast, rough and NOW, but that was exactly why Sam needed Dean, because Dean could give that to her where Sam… Sam had tried it once and he did more damage than good.

He heard the snap of a button, the slide of a zipper and his eyes moved towards the back of Dean's head, the way it followed those shorts down over her legs, completely missing the glistening core as Ali sat, spread open for Sam to see as Dean slipped them off.

His brother was careful and gentle as he moved back up and Sam ducked around a few beams to finally get a better view. He knew the moment his brother's tongue touched her clit, the instant it slid through her folds because Ali wasn't so quiet anymore and her arms, as she let go of his hair, braced against the hood of the car, shaking.

Sam's reaction to Dean's fingers pressing into her was instant, as he felt his balls tighten when she did that familiar noise and her hips bucked up, trying to ride them harder. Sam watched her face, eyes closed tightly, bottom lip between her teeth before she let it go and her lips parted. He knew exactly when she began to reach that point of no return.

Her whole body shook, the ball of her foot vibrated on the bumper of the car, the toes of the one slung over Dean's shoulder curled and she dropped her head back. Her head nearly touching the windshield, and the noises.

Sam was dead, just so dead, because he wanted to be buried deep in her. FUCK! He wanted to help Dean get her to make that sound, but he stayed still, stroking deep and pulling hard at his head.

"Dean… fuck… wait…" She pleaded, her hand suddenly going down to grasp his hair, trying to pull him away, but Dean's fingers dug into her hips, keeping her there. "Oh… oh, my God. Dean!... oh, wait… Dean."

Sam had been at the receiving end of one of her mantras, his name flowing from her lips as if it were breath. She was coming, and fast. That was when he heard her hit the car. Her arms had finally given out.

Dean let the torture go on for a minute more before he slowly made his way up her body, coming to rest with what had to be a hell of a hard-on pressed tight against her. Sam watched his hips side against the wetness that he had created and heard his brother drag in a deep breath.

"Dean, please, I need you." She was all words today, hands everywhere on his bare skin and suddenly they slipped between them and Dean laughed again, this time against her lips as he denied her the kiss she arched up for.

"Where do you need me, baby?" He was taunting her, but she seemed to only respond to it. On any other given day, in any other situation, she would have punched him, but at that moment, she was only whimpering, her body begging. "Tell me where you want me." Dean himself seemed breathless, like he was doing it to himself as well, letting her push the jeans he was wearing down over his hips. Until the moment Sam knew he had sprung free because Dean raised his head, eyes closed, for just a second before he brought his lips down, kissing her. "Ali… I'm begging you, tell me."

Oh, Dean had his kinks alright, like holding himself back until he absolutely had permission to go forward. This was his submissive thing, all control on the outside, letting go during sex.

It was all on Ali now, but he gasped when she wrapped her hands around him, not that Ali could get a full grip, because just like Sam, Dean wasn't a small man. He rode the waves though, the way she moved, and he continued to thrust forward as if he were already in her instead of in her small hand, gently and calculated, pulling every sensation.

"Now," Ali whispered. Sam could imagine her lining him up, slipping him just slightly between her folds and her eyes closed. Dean held her hips, his muscles stopping to let the feel of her surround him as he slowly pushed in, slipped back only a bit before moving in slower. Another one of his kinks was the absolute torture of letting her have control, but in that position, at that moment. "Faster."

"No!"

That one shook Sam! It was deep, alpha territory and though Sam knew she was his, that he was totally in love with her, the thought of Dean giving her orders, standing firm right then made everything immediately hotter than hell.

"Oh, God." Ali whispered through clenched teeth as Dean finally sat buried flush against her skin, something that nine inches and his girth shouldn't have been able to accomplish, but that was why Dean needed slow and steady, he wanted to be all in her and Ali's fingers curled against his shoulders, diggin in with the small nails she sported, and Dean growled.

Dean started to move and all Sam could think was finally because his hand on his own cock followed Dean's movements, the slide up, the thrust down and he watched Ali's expression with every movement.

Dean's lips came down, sucking on her nipple as he created a pace that tortured him but touched every spot in her that he knew about, every change in angle a way to draw the noises he loved so much out of her.

Sam wanted to watch her ride him, to turn the tables on Dean, but it wasn't happening, not this time. It was an image that he loved to have in his head, the way her breast bounced when she did, the way her body moved, and Sam clenched his jaw.

Dean better hurry but cause Sam wasn't lasting very much longer.

Dean, as if feeling his brother's end, started to shift, his movements becoming erratic, the strokes way too uncontrolled for Dean and the noises, the moans were feral, as if he had finally lost it.

He kissed her then, moaning into her mouth as she wrapped both arms tightly around Dean's neck and he brought her close to him, one arm on the car, the other around her waist, pumping quickly into her.

Ali bit her lip, which in turn made Sam bite his because he knew what was coming next. She was, and SHE moaned loudly, a primal sound that made Sam's balls tighten against him hard enough for him to nearly lose it, but he held back, placed his lower arm against the metal post in front of him and with part of his forehead against the warm flesh, he watched her, watched her push Dean back so that he had no choice but to pull out and suddenly she was on her knees.

Sam held the growl in as she sucked down on Dean's cock, the man she ministered to grabbing a fist full of hair as his head leaned back and he spread his legs the best his jeans would let him. Sam knew that face and suddenly Dean's eyes were screwed tightly shut and he was baring teeth as he held her still, thrusting into the warmth of her mouth, no doubt coming hard.

Sam bit down on his cheek, holding back the moans as his body betrayed him as he coated that damn painted post a new color. He loved Ali more at that moment for the games she played with him because he came without a sound, watching as Ali, in all her naked glory, stood and slid back on the car.

Sam caught his breath as the last of his energy was spent holding his legs straight as they threatened to come out from underneath him and Dean placed both hands on either side of her thighs as he rested his forehead against her chest.

Ali gently pet the back of Dean's head, fingers running through his hair, down his neck and over his shoulders, her eyes half-laden as she enjoyed the way that he felt under her touch, but Sam watched as she raised those blue eyes to him, winked, and slowly lowered them.

Sam shook his head, didn't realized that she knew he was in the room but swallowed hard at the thought of what she would do to him later to get back at him for staying so silent, or not joining in. For now, he watched her take care of Dean, move her hands over him to calm his body as he pushed her back against the car, covering her with his own.

For just a moment, all three of them did nothing but breath.
