It started slowly. At first it was discomfort, one that left you wiggling in your jeans. You felt hot and no amount of air conditioning was helping. You moved in your seat as Dean drove through the small time. The three of you had arrived that morning, opting to eat at the local diner before investigating what was going on. A couple had eaten each other to death the night before which threw up alarm bells for the hunters. You were Sam’s best friend, a relationship that had begun in college. It wasn’t until you had an encounter with a werewolf four months after Sam left that you decided to join the boys on their hunts.
“You gotta take a piss or something?” Dean asked after he had noticed you were moving around in the backseat. You blushed when you met his eyes in the mirror.
“Leave her alone, Dean.” Sam smacked his brother playfully. You were grateful for this, as you always were for Sam. Coincidentally after he spoke, the need to move increased. You squeezed your eyes shut and breathed deeply.
You were contemplating asking Dean to pull over when the car stopped. You opened your eyes to find the motel you three would be staying in that night. Dean was already opening the door to the room, but Sam stood in front of your open door with his hand held out, ever the gentleman. You grasped his hand in yours and an actual whimper hummed in your throat. It was like your senses were heightened and Sam was the key to making it all better. Sam looked at you with his head cocked to the side.
“You alright?” He asked as you climbed out of the car. Oh God, his mouth, the way his lips moved when he talked, you wanted them on you, every part of you.
“Yeah.” You whispered, clenching your other hand in a fist. You shouldn’t be thinking of your best friend in that way. At least, not when he was leading you into your shared motel room with his brother. It wasn’t like the thought hadn’t crossed your mind, late at night, with your hand between your legs. You had walked in on Sam with Jessica once, back in the first few months of college. And God did that image give you something to think about. You mostly thought about how easily Sam could pin you on the bed, kiss and suck his way down your body until he reached your core, right where you needed him most. The idea of him devouring you like a starved animal, hands wrapped around your thighs, tongue-
“God, Cass, I thought you didn’t need to eat!” Dean exclaimed as the angel took another bite of his burger. Somehow you had missed entering the room and Castiel appearing inside. You let go of Sam’s hand and beelined to the bathroom. You shut the door and locked it, but not before hearing Dean gloat about how his earlier question had been correct.
You looked in the mirror and analyzed your blown pupils. You scoffed at yourself, splashing cold water onto your face. Why were you acting like a cat in heat? You had more self control than this. It didn’t make sense. You were fine this morning, yet now you were ready to grind yourself down on the edge of the bathtub.
You must have been in there a while because there was a knock on the door and you heard your name.
“I-I’m okay.” You stuttered out while holding back moans. It was Sam, who never wanted you to be uncomfortable. You bit down on your lip as you slipped a hand in your pants. After a few minutes of dissatisfying touching, you knew you had to stop and go back out into the room. When you opened the door there were three pairs of eyes on you, one playful, one uninterested, and one worried. You cleared your throat and shuffled to the table before taking a seat. Silence, aside from Castiel’s chewing, filled the room. You pulled out your laptop from the bags that had been brought in and began researching. What, you didn’t know, but it beat trying to avoid Sam’s gaze.
----
It was official: you were horny for Sam Winchester. It was bad, worse than it had been that afternoon. You all had figured out that one of the four horsemen, Famine, was in town, and he was looking for something to satisfy his hunger. It explained everything. Cass’ insatiable hunger and your insatiable need. Even Sam was going thirsty for some demon blood.
Now, you stood, or more squirmed, in the motel room as the boys created a plan. They were starting to suspect something was wrong with you, they just couldn’t figure it out. Dean was a bit more clued into the fact that you seemed to whimper every time you looked in Sam’s direction. Sam, completely clueless to this, had been trying to get you alone in hopes you would tell him what was wrong.
“We find Famine, take his little ring, and everyone will be back to normal.” Dean said, slapping his hands on his lap. You hugged yourself, chewing absentmindedly at your thumbnail in an attempt to stop the desire from coming out of you.
“Dean-” Sam’s voice made you melt and a small moan escaped your lips. The brothers looked at you before turning back to the conversation.
“-I can’t go. The demons-”
“I get it.” Dean interrupted Sam. He knew he couldn’t expect Sam to risk something like this. He had it handled. He had Castiel to help. He would’ve had you also, but he could tell you were ready to pounce on Sam. Your resolve was breaking. There wasn’t much more you could do. You decided - you were going to ask Sam to help you get over this.
“Sam,” You breathed out as you walked to him. Your legs were wobbly. You watched Sam shoot up from his seat, but before you could get to him Dean was grabbing both of your wrists. You whined, trying to pull away. You needed Sam, needed his body, his c-
“No.” Dean spoke sternly, pulling you to the door. He had to get you another room and lock you in. It was for your own good.
“Wait, let her g-” Sam tried to walk to you but Castiel, even in his hungry state, stepped in front of him. You yanked against Dean but he was stronger than you.
“Not right now, man.” Dean spoke as he dragged you out.
“What’s wrong with her?!” Sam was desperate. He needed to know why he couldn’t be around you.
“I think you know.” Castiel said before turning his attention back to his food. Sam shook his head and tried to think. Realization came across his face as he put it all together.
----
An hour had passed since Dean left you. He had locked you in the bathroom of a room as far from the original room that they had available. You had somehow gotten worse. You were bucking from the ground, trying to find something to alleviate the pain. It was horrible. You knew Sam was close. You could feel it. You needed him. The door was locked from the outside, but you were pulling on the handle, trying to get it open.
“Please,” You whined out. You banged on the door, trying to break it down. You whimpered a few times when you felt the fabric of your jeans rub against you. You had grown stronger since joining the boys. You could do this. You needed Sam.
The sound of wood cracking encouraged your efforts. You slammed your body up against the door and hit it with your fists until you felt it give way. You fell to the ground surrounded by the scattered pieces of wood from the door. Your recovery was quick and was sped up by the overwhelming need bubbling in you. You stumbled to the door of the room, which was, stupidly on Dean’s part, simply locked with the deadbolt. You ran out into the night like a caged animal escaping. You searched around trying to find the room where you knew Sam was.
There. Room 12. You ran for it, panting as your core grew wetter. You reached the room, shuffling around for the key that Dean had forgotten to take from you. You fumbled to unlock the door. You could already smell Sam, hear his own struggle to get his fix. You searched the room trying to find him.
“Sammy…” You whined out and clutched your stomach. You couldn’t find him, even though you knew he was here. You heard your name muffled through the door to the bathroom. Of course! Dean had hidden him in the same place he had put you. You practically ran to the door, yanking it open. There he was, handcuffed to the sink and looking up at you with those puppy dog eyes. You whimpered and fell to your knees next to him.
“Sammy, it hurts.” You said, gripping onto his shirt. Sam scrunched his eyebrows in worry and understanding. With his free hand he rubbed your side in an attempt to soothe you.
“I know, honey.” He breathed out as you leaned on him.
“Please, Sammy, help me. Please.” You whimpered and breathed in his scent.
“I don’t know if you-” He began.
“No, I do, I do, I do.” You chanted as his hand gripped onto your side. You could see him roll his head to the side. He could tell you were in pain. It wasn’t like he didn’t want to help. He did, more than anything in the world. He had wanted you since you joined him and Dean on the road. The time was never right, his confidence never high enough. And now he had a chance. The only problem was he didn’t know if you actually wanted it or if it was the old man controlling your desire. When Sam was silent to your begging, you moved in closer.
“Sammy, please… it hurts so bad… I want you… all of you…” You moaned out. Red hot need flashed across your vision. It was getting harder for Sam to not touch you in the way you both wanted. The final crush of his hesitancy was the whimper that came out of you when he took his hand off of you.
“Let me see you, baby.” His tone was delicate even when his words were dirty. You were quick to pull your clothes off. You didn’t care where they went and threw them in every direction. You were left naked and kneeling next to him. His eyes raked down your body before stopping on your acing core. You watched him, whining. He traced a finger across your burning skin. He stopped just before reaching your wetness.
“Please…” You breathed. He flicked his gaze to your eyes momentarily before moving his hand. He started slow, rubbing your clit mindfully. You fell backwards in pleasure but made sure you were still close enough for Sam to touch you. Sam’s pace never slowed or quickened, which made you buck your hips up. He pulled his hand away, leaving you cold and whiny.
“Ah ah,” Sam locked eyes with you, “let me do it.” He placed his hand back where it was to continue his rubbing. Your chest heaved as you willed yourself to stay still. God, you needed this. Your hand moved to your breasts. You toyed with your nipples. This made Sam pull at the cuff around his other wrist. He wanted to touch you, touch all of you. Damn Dean for restraining him like this.
“Just like that, baby, rub them just like that.” He slipped a finger in you. You moaned and clenched around it. He swore under his breath as he moved his hand. You felt like heaven and he hadn’t even had you around his cock yet.
“Yes, Sammy, yes.” You encouraged him. Looking at him from your spot on the floor, you could tell he was getting hard. You wanted to help him, helping him helped you. You moved to get up when Sam pulled his hand back again.
“I said, no moving.” He growled and moved his hips to hide the growing erection. You collapsed on the floor, desperate for him again.
“Wanna make you feel good, Sammy.” You mumbled as you felt not just one, but two fingers slip in. Sam sighed in pleasure, loving how you felt on his hand.
“You are, baby. You can have it, have it all. Just wanna make you come first.” His gentle tone only made you louder. You ran your hands down your body, sparks of pleasure erupting wherever you touched. You were close, so so close. You squeezed your eyes shut as Sam sped up the pace.
“So close, Sam, so so so…” You trailed off, the words falling off your tongue as he curled his fingers. He smiled devilishly, and if you didn’t know any better, or if you were in the headspace to even think, you would’ve thought he was possessed. No, this was completely and wholly Sam Winchester.
“That’s good, baby, come on. Come all undone for me.” He cooed. His words were what sent you over the edge, waves crashing down as you moaned through a bitten lip. The moment of reprieve from the pain was short lived as the need seemed to multiply. You figured this must be what torture was. You turned to your hands and knees before crawling to Sam. He groaned as he watched you look up at him, asking for permission to undress him. He nodded and your hands flew to his zipper. You unbuttoned his jeans, pulling them down his body with his boxers.
His cock sprang free, looking achingly hard. You sucked in a breath, the sight making your clit throb. You moved a hand to touch him, but was stopped by his hand on your wrist. Your eyes shot to his.
“I want you around me.” His words were almost a beg, like he was just as needy for this as you were. You whimpered in reply, a new wave of pleasure washing over you. You climbed on top of him so you were chest to chest. He looked in your eyes before crashing his lips into yours. It was sloppy and full of desire. His hand gripped your hip, kneading the skin there. You groaned in response. Your arms wrapped around his neck and you tried to hold him as close to you as possible. His hand snaked down to position himself with your hole. He broke the kiss to speak.
“Ready, baby?” He asked. You answered by sinking down onto him with a sigh. You kissed him again, grinding your hips. He helped you move, lifting you with one arm only to guide you back down. His lips left yours, moving down your face then to your neck. He nipped at your skin sharply before kissing it better.
SamSamSamSamSamSam. The only thing in your mind was Sam. His name was racing through your brain in a never ending loop. He left little marks on you everywhere, causing you you speed up your movements. Your fingers tangled in his hair. You needed him closer, needed him deeper.
“God, you feel so good, baby. Just like I dreamed about.” Sam grunted out against your skin. Your walls were warm and tight around him. He could feel you tighten around him when he spoke, which only motivated him to keep going. His words made you moan. You loved this, and though the instant need for it had been brought on against your will, you had been dreaming about this moment for a while.
The room was filled with breathy moans and the sounds of sex. You pulled Sam's head back by his hair, gentle enough, before kissing him again. It was sloppy and wet, full of lust. You could feel yourself growing closer to orgasm again. It was insane how this felt. Most guys hadn't ever gotten you off once, much less twice in the same night. You whimpered into his mouth and felt a smile curve up his face. He was glad he could bring such pleasure to you.
The final breaking point for you was when you felt his hand holding you grip onto the soft fat of your bottom. You let out a few breathy whines as you felt Sam come a second later. You didn't care that the two of you had forgotten to use a condom in your sex driven states. None of that mattered. All that mattered was the euphoric high of multiple orgasms was washing over you as you stayed on Sam. Neither of you were moving anymore. He was still inside you when you let your arms fall to his chest. Your head lolled to its side onto his shoulder and he wrapped his arm around you.
“You okay, baby?” He said in between pants. You simply nodded. The overwhelming need to go for another round wasn't coming and you were so glad for it. Finally, you were at peace. Dean and Castiel must have gotten Famine’s ring somehow. You didn't think of what this meant until you heard the door to the motel room open.
“Sam-” Dean began, but was cut off by the sight of the two of you on the bathroom floor, Sam still cuffed to the sink. Castiel appeared behind Dean.
“She wasn't there.” He stated in a monotone after seemingly being sent to check up on you.
“Yeah, I got that.” Dean mumbled. Sam looked up at him sheepishly. You were starting to doze off. The energy it had taken all day to not be able to get off was taking a toll on you. Dean cleared his throat before grabbing a blanket off the bed. He draped it over you in an attempt to keep some of your modesty in tact.
“Can you, ya know?” Sam questioned while rattling the handcuffs attached to him. Dean pulled a key from his pocket and quickly freed his younger brother.
“We'll talk about this later.” Dean said before swiftly getting out of the bathroom and shutting the door behind him.
