When Dean walked in Sam was standing in the middle of their shared room. She was soaking wet, hair long brown hair sticking to her face and her arms covering her chest.
She jumped, startled, when Dean walked in the room. He was also soaked, his clothes dripping on the floor. Sam didn’t remember him ever looking this handsome before.
“Where’s Bob?” She asked faintly, dreading the answer.
“Not here,” Dean said, his voice low and hoarse, and walked closer to her.
Yes, the person with him was his brother, but it also wasn’t. What if there was one person in this world who knew him better than himself, one person he would die for, and kill for, and what if this one person was the most beautiful girl he had ever seen, and what if this girl wanted him just as much?
Sam watched as he closed the distance between them. She knew she was breathing erratically, and she didn’t know whether the goosebumps were out of cold or excitement, or both. She shivered with anticipation when they were inches apart.
“Sam…” Dean started.
“Shh…” She placed a soft finger on even softer lips. Sam shut her mind to a part of her who screamed against the feelings stirring her further into Dean. She shut her mind to who she had been before, because right now there was only one thing she needed, and Dean was there to give it to her.
She captured his lips into a firm kiss and raked her fingers through his hair, tugging urgently and drugging him with her perfume and her need.
Dean shut his eyes and kissed her with the fire that burned in his lower belly. He wrapped strong arms around her body and warmed her skin up with the heat of his desire.
Sam sucked on the greedy tongue exploring her mouth and pressed herself into the larger frame of his body. She raised her arms helpfully when Dean slid her blouse off over her head, and suddenly she found herself shy as he studied her bra and the shape of her breasts.
Dean knew he was already rock hard in his pants. His body was ready to take Sam, it needed to take her, and yet his fingers were shaky when he reached for her bra and undid it quickly.
Sam arched an eyebrow, amused at his skill.
“What?” Dean blushed. “Been doing this for a while,” He smiled cockily, but it was his brother, and Sam could tell that Dean was nervous and trying to play it cool. She might have laughed at the scene if it weren’t for the fact that she was naked from the waist up, which Dean made sure she remembered when he cupped her breasts gently.
Sam’s eyes fell shut and she sucked in her breath. His fingers were smooth and feathery. They brushed over her nipples and made the hairs stand on the back of her neck.
“You’re so fucking beautiful, Sammy,” Dean whispered in her ear, cupping those breasts he had secretly longed to touch for many a night.
She smiled and relished the soft grazing of the tip of his nose against the column of her neck. Dean kissed the spot where her shoulder and neck met, and Sam writhed in his arms.
“Dean…” she whispered throatily.
He loved the sound. He loved everything about her. He even loved the fact that Sam was his Sam, the one and only, hell, he might as well admit that. Dean lowered his mouth and kissed every inch of her skin, and when his lips brushed against her nipples and his tongue toyed with them, Sam’s fingernails bit into his arms and she squeezed tightly.
When Dean was done licking and kissing, Sam felt herself throb between her legs, the feeling like a piercing tingle of arousal that made it hard to think.
Her fingers were once again messing his hair, tugging and holding on as Dean’s tongue flicked over her nipples slowly and relentlessly.
Her breathing became louder and by the time Dean went up to kiss her again she felt hot and bothered. Sam started tugging at the hem of his shirt until Dean got the message and helped himself off of it.
What met Sam’s eyes made her smile and focus piercing hazel eyes appreciatively at the sight. Dean watched, his heart slamming in his chest, as Sam raised her hands and let her fingertips touch his naked chest.
The moment she did so they both gasped in unison, like sheer electricity had just crossed them. Dean’s chest heaved up and down under her soft, tentative explorations of his abdomen.
Sam licked at her lips and studied Dean’s body with her fingers. His skin was hot under her touch, and she marvelled at the hardness of the muscles in there. Not so long ago she herself had a body much like that, and though she had never given it much thought, now it seemed like something so beautiful, so…. desirable… Sam started kneading possessively, until Dean shut his eyes and simply enjoyed the moment.
His strong hands covered hers, and he pulled her closer against himself gently. Sam let herself go and wrapped her arms around him, squeezing his larger frame and cupping his face. Their mouths met once again as Dean slid his usually harsh, and now so gentle hands all over her back, relaxing and teasing.
Dean’s tongue was all over her mouth as he guided them towards one of the beds. When Sam’s knees touched the edge she let him lay her down slowly, but with the certainty that nothing could make them stop now.
Dean kissed her lips and her neck, and his fingers worked the button of her jeans before sliding them off. Sam shivered when his hands grasped her thighs firmly, stroking her legs up to her hips, where he held on tightly before nuzzling against her underwear.
“Sammy… you tell me if you change your mind, okay?” He asked, his concern for her evident in his face. But Sam would have none of it. She felt her body alive, vibrating in a frequency unknown to her, and addictive to her awakening senses. Sam had experienced sex many times, but definitely never like the feelings stirring inside him right now. He wanted to explore this, he needed to know what it was like to give in to the arousal pulsing between her legs and clouding her thoughts. It was only fitting that Dean, whom he trusted most in his life, would be the one taking him there.
“I’m okay,” she reassured him.
Dean smiled provocatively and his teeth found her panties. Sam watched as he removed them with his mouth, her heart beating in loud, wild thuds in her chest. For a moment she felt exposed and scared, but Dean was there, looking into her eyes again, and Sam relaxed.
Her fingers caressed his face and pulled him in for a kiss. She loved the feeling of his stubble against her cheek.
Dean kissed her more passionately this time, and his right hand slid down her body and found the heat of her arousal. He knew what he was looking for when his fingers explored soft folds of skin. He felt her wetness cover his fingertips and sucked in his breath.
“Fuck, Sammy,” He whispered, breaking the kiss. His fingers touched her more intently and Sam realized the reason behind his lust, darkened eyes. She was soaking wet.
Sam felt her cheeks growing hot and she blushed crimson before she could stop. She knew what a girl’s body was like, hell, she had been on Dean’s end of that dance many times, and yet… how different it was to actually feel everything.
Her embarrassment disappeared when Dean’s fingertip touched a soft, sensitive bud between his legs that made her moan and arch into him.
“This good?” Dean spoke, his voice low and sultry. He fingered her clit without any hurry, relishing every gentle circling of his fingertip.
“Hmm!” Sam moaned. The pleasure was sharp and her mind felt delirious. How could something feel so sensitive, so good? “Dean…” She whispered faintly, vaguely aware that her thighs had opened further to allow him more access.
Dean drank in the pleasure twisting Sam’s beautiful features. He fingered her slowly but certainly, until she was breathing fast and her eyes - his brother’s eyes - were definitely dark with lust.
“I have to taste you,” Dean spoke hotly and moved. It took Sam a while to realize where he was going.
Dean’s hands wrapped around her thighs and he pulled her closer and open to his lips. Sam’s heart slammed against her chest and when she saw Dean’s green eyes fall shut and his tongue dart out as he leaned in closer, she sucked in her breath and bit on her bottom lip.
Dean licked her center and tasted her arousal, and Sam nearly tugged Dean’s hair off at the feeling.
“Fuck! Dean!” She cried out when he started licking her clit, his hands holding her tightly by the hipbones.
Dean felt a shiver rake him head to toe at Sam’s intense reaction. He knew his brother must have gotten hundreds of blow jobs in his life, and he loved the fact that no one had ever made Sam feel that way. Only he would be able to do that, to see that, to taste that.
“Hmmm!” Sam moaned and her fingers raked Dean’s hair, pressing him into her warm center, not caring if she seemed desperate, because the way Dean kept using his tongue was certainly making her lose her mind.
Dean did his best. He knew he was good at it, but it was Sam. His ego was inflated - his brother would know just how good he was with chicks - but the real kick was that his brother would actually get off on this skill.
“I… Dean, I…” Sam felt the arousal building up to something unstoppable.
Dean loved her pleas and the ragged cadence of her erratic breathing. He wanted to feel Sam shatter and come undone against his mouth, so he he used the tip of his tongue to tease mercilessly, enjoying the painful way that Sam kept tugging at his hair.
“Dean!” Sam started shaking. Goosebumps broke all over her skin and her muscles tensed. Her lips parted and a broken cry of pleasure echoed in the room as she came, her eyes fiercely shut as her brain seemed to shut down for a few seconds.
Dean’s cock pulsed in response to tasting her orgasm. He sucked and licked, letting Sam ride it out for as long as possible, but eventually she pulled at him, sensitive and soft.
Dean went up to look into her eyes and found a lazy, content smile on her lips.
“Was that good?” He teased, caressing her face.
“Fuck yeah,” she managed to reply. She pulled Dean to her face and kissed him, and when she tasted herself in his lips and on his tongue it made her hot and ready for more. That was a taste Sam had felt before, and that had aroused him before, and that now, knowing it belonged to him and that it was all over his brother’s mouth, just made him crave more.
“Sam,” Dean broke the kiss and stared into her eyes. He was painfully hard in his pants, but he needed to be sure. “We could stop here, you know?” He took her hand and kissed her fingers. “There’s no need to-“
Sam used her other hand to reach down his pants and squeeze, making Dean’s argument dissolve into a moan of need.
“I don’t think so,” she said and let her hand slide within his jeans and underwear. “Before I go back to normal I want to feel everything.” She squeezed him at her last word.
Dean groaned and soon helped her remove his clothing. Once he was naked, he settled between her thighs, his cock pressed against her smooth skin, and they kissed slowly and wetly for a while. Dean thrust tentatively against her, letting himself go inch by inch closer to her center.
When Sam felt the tip of him at her entrance she shuddered and felt adrenaline run in her blood. ‘Dean. He’s my brother. My big brother. And a man.’
“Sam? Dean asked, feeling her heat and wetness licking at his sensitive tip. Dean looked at the beautiful girl beneath him, and he saw a woman, but he also saw the only person in the world he would die for without thinking twice. His heart was bursting with love. “This might be completely fucked up and wrong, but you know I love you, right?”
Sam nodded. “I love you too.”
“I don’t wanna hurt you.”
“You won’t.”
Sam said and then she pushed herself against his erection, the wetness inside her making Dean slide in easily all the way into her body, until he moaned with pleasure and Sam let out a cry of surprise and pain.
“Sam?” Dean stood absolutely still inside her, he felt his cock pulse against the velvet like smoothness of her. “Sam what happened?” He frowned and looked at Sam’s face, which was twisted in evident pain and discomfort.
“I… I don’t know…” she said, and she held on to him, her fingernails biting into the skin of his arms.
“I hurt you,” Dean widened his eyes with worry. “Damn, I’m pulling out-“
“No, wait,” Sam squeezed him between her legs. “Don’t move. Just… just give me a minute,” she said, breathing slowly in and out, trying to relax.
“What happened? What did I do?” Dean fretted
Sam looked puzzled and lost.
Then, as a thought occurred slowly to him, Dean reached a hand between their connected bodies, let himself slide out a little and touched her. Sam moaned slightly at the movement and shut her eyes. When she opened them again Dean’s fingers were before her eyes, and there was blood on them.
They locked eyes and their connection was thick and intense.
“You were a virgin?!”
“No, of course not!” Sam protested immediately.
“I know you weren’t, you, my brother Sam… but girl Sam?” Dean tried.
Sam thought about it.
“I… I guess this body is indeed brand new,” she smiled softly.
“Damn. I have to stop.”
“No!”
“Sam-“
“Dean, I’m fine.”
“I hurt you.”
“And it will have been in vain unless you keep going,” she challenged him.
Dean’s heart was beating fast. He wanted to take her, but he couldn’t hurt her, or his brother.
“Stop thinking,” Sam said. He knew his brother and could tell exactly the doubts that were crossing his mind. “Come here,” Sam made a move and pulled Dean closer, arching into him and causing their bodies to be joined again.
Dean groaned at the feeling and let himself be cuddled in her arms.
“That’s it, much better,” she whispered, moving her hips and causing Dean to pick up a rhythm.
“Am I hurting you?” Dean asked, concerned, at the same time he moved tentatively in and out.
“No.”
“You mean it?”
“Yes,” Sam smiled. It was uncomfortable at first, but the more Dean moved, slowly and gently, the easier it was to relax and give in to the feeling.
Sam closed her eyes and let her mind wander. She relished the thrusts and the weight of Dean’s body on top of hers. It was so unlike anything he had experienced, he wished time would go slower so this girl - himself - could enjoy it more. If tomorrow they found the cure to change him back, fine, but tonight Sam was this girl who felt every inch of his brother’s desire throbbing within her body, and it was amazing.
She ran her hands up and down his back and squeezed around Dean, smiling when that caused him to groan.
“Sammy… Sam, that’s so fucking good,” he purred in her ear, his hips moving faster now.
Although she was still aroused, Sam didn’t think she would have another orgasm. Yet, the experience of feeling Dean move inside her, filling her over and over again with his hard, hot need for her was addictive, and she opened her eyes not to miss a single detail of his face when he started to lose control.
Dean panted and squeezed her hips with his large hands before running them all over her body, her breasts and her face. He wanted all of her, every inch. He wanted to have Sam - all of Sam, him and her - he wanted to know her as deeply as no one ever had, and he wanted to lose himself to the feeling of peace he felt when she looked into his eyes and smiled.
“Sam, I won’t last…”
“That’s alright. Let it go.” She met his thrusts with eager hips, that swiveled against his cock causing him to moan and shudder. Sam smiled, pleased, at the sight of Dean descending into chaos. “C’mon, Dean… fuck me.”
He looked into her eyes and smiled lustfully at what he saw there. He grabbed her left thigh and opened her further to his thrusts, and then he slammed into her like there was no tomorrow.
Sam moaned delightfully at the strength behind each thrust, she squeezed and arched until she felt Dean slam one last time and keep still, his lips parted in a silent cry of pleasure as he came, pulsing and releasing hotly inside her.
Sam knew she was trying to memorize every detail of Dean’s over the edge face before he finally collapsed on top of her, his sweaty hair nestling against her soft breasts.
“Damn…” Dean whispered, his hands holding on to her as if to keep everything else from spinning inside his mind.
Sam raked his wet hair and squeezed him between her thighs.
“Hm…” Dean moaned lazily and pulled out slowly, lying right beside her and looking into her eyes.
Sam felt wetness between her legs, showing how real everything had just been.
“Are you alright?” Dean asked, caressing her hair.
She nodded. She was alright - physically at least.
What she didn’t say was how much of a mess she felt inside looking into his green eyes. Sam had known Dean since ever. He knew no life without that man lying beside him. Then why did it feel like Dean was so different now? He wasn’t the one who had changed…
Sam swallowed hard and snuggled closer to Dean, burying her face against his chest, unwilling to keep looking him in the eyes. She enjoyed the feeling of his fingers tangling in her hair.
“Dean? We’re going to change me back, right?” she asked, softly.
Dean hesitated for a moment before clutching her tightly against him.
“Of course! We’ll bring you back.”
Sam nodded.
She wanted to believe she felt relief at Dean’s words, but her muscles were tense and her thoughts cast shadows in her eyes.
“I have no doubt of that,” Dean reassured Sam again, but as his mouth promised change, his arms wrapped Sam tightly, unwilling to let go.
It was within a strange new sort of need that they fell asleep in each other’s arms that night, hoping, perhaps, that the morning might bring a clarity they were both unable to find.
