Summary: Dean tries to break the news to his father that Sammy isn't interested in carrying on the family business. John handles it like an ex-Marine would, and Dean storms off to the shores to cool down after the heated debate. There, he is entranced by a water succubus. Will his father realize what happened before it's too late?

Tag to "After School Special." Dean is 17 and Sam is 13.

Sam made his way quickly to the edge of the surf, looking around to make sure no one else was by the beach. He was both relieved and terrified to find he was completely alone; nothing but the sound of his own heartbeat pounding wildly in his ears. He held his gun tightly behind his back and waited, unsure of how he was going to get her to surface.

He waited for three minutes before his nerves started to get the better of him. He kept glancing backwards, making sure the others weren't running out of their motel room to kick his ass just yet. On one of these particular occasions, he heard rippling in the water behind him and froze.

"I was hoping you'd come back to play, Deano," a soft voice floated over the surface of the water behind him, sending chills down his spine. Sam held his breath, eyes locked on the motel room door, knowing it wouldn't take long for her to figure out he wasn't his brother. He was right.

"Well this is unexpected… Little Sammy Winchester, trying to catch me in a trap?"

Sam slowly turned his head back towards the water, his heart sinking into his stomach as soon as his eyes verified what his ears had already told him; Sarina was standing directly behind him, less than three inches away. He stumbled back a few steps in surprise.

"N-no, that's not it. I came alone. I want to make a deal with you."

Sarina glanced up and down the beach just as Sam had done, verifying that the boy was indeed telling the truth. "Oh, this is just adorable!" she crowed in delight. "Let me guess, you want to take your big brother's place, is that it?"

"I'll do whatever it takes for you to leave him alone. You've hurt him enough."

"My dear boy, it was never my intent to hurt your brother. It's your father who needed to be punished. Dean is just… a means to an end. It's just a perk he happens to be so damn handsome." She smirked as she recalled their last intimate encounter.

Sam held back a growl. "You got what you wanted, okay? My dad was a mess for what you did to Dean. Take the win and stay away from my family."

She took a threatening step closer. "Or what exactly?"

"Or I'll give you a new hole that will put you down permanently." He drew his gun swiftly, aiming at her heart.

It unnerved Sam to no end that she didn't even flinch. In fact, she seemed perfectly at ease, making him wonder if he had severely miscalculated the situation. Apparently, she knew something he didn't.

"Sweetie, you don't want to do that." Her eyes flashed and her soft voice seemed to echo through his head, confusing him.

"I… I don't?"

"No, baby. Children shouldn't play with guns. Toss it into the sand before you hurt yourself."

Sam tried to fight her words, but his arm responded against his will and tossed the gun a few feet away.

"That's a good boy. Now why don't you come on over here and give Sarina a nice big hug?"

Sam started shuffling forward, desperately trying to run in the opposite direction. He was startled to a halt when another voice cut through the air.

"Sammy! Get away from her!"

Dean…

He glanced over his shoulder to see his big brother stumbling over the uneven earth in his rush to get to the shoreline.

"There's our knight in shinning armor!" A slimy arm wrapped tightly around the youngest Winchester's neck before he could move another inch. "I don't think so, Sammy Boy. You're staying right here with me." Just like that, the spell was lifted off of Sam and his hands immediately rose to grip her arm in defense.

Dean slid to a stop a few feet away when he saw that she had his brother in a headlock. He held his arms out in surrender. "Whoa whoa whoa! Don't hurt him!"

John and Bobby were a few steps behind, not as fast as Dean these days, but equally as pissed off.

"Stop right there!" she shouted to the men who froze immediately, unwilling to press their luck when Sam's life was at stake. "Move back up the beach or I'll snap his neck in half."

She turned her focus back onto Dean who also took half a step backwards, following her orders. "Not you, sweetheart. You can stay right where you are."

Dean glanced back at his father and Bobby, taking care to keep her in his periphery as he watched the two older men reluctantly fall back. They did, however, keep their guns trained on the Rusalka. Either she wasn't strong enough to put them all under her power, or she didn't find them to be a big enough threat to bother.

"This must be my lucky day. Two handsome Winchester boys willing to do as I command, and daddy Winchester, in the best seat in the house to watch the show."

Dean ignored her words. "Let Sammy go. We both know he's too young for you."

"Oh, I'm not so sure about that. He's what…? Eleven? Twelve? I've had younger." She smiled cruelly, turning Dean's stomach and allowing his anger to take over his deep-seated fear.

"Hey, if you want to try your luck on a little kid, that's your problem. I just assumed you'd want to finish the job you started since you failed so spectacularly last time. But if you're too afraid to take on someone your own size…"

"Are you baiting me, Dean?" She sounded incredulous, yet amused.

Dean forced himself to shrug nonchalantly. "Just sayin'… If you don't think you can handle me without your little love potion, I can understand why you'd go for the easier mark."

She considered his words for a moment, then made her decision. "Take off your shirt, Dean."

Dean frowned, taken aback by the sudden order. "What?"

"You heard me. Do it now, or no deal."

"Aren't you gonna buy me a drink first?"

"Don't do it, Dean!" Sam shouted, terrified that he was responsible for putting his brother in this position once again. "Just run! Don't let her…!"

"Silence!" Sarina barked, tightening her grip on Sam's throat till his voice was cut off.

"Stop it!" Dean shouted back angrily as Sam choked and clawed feebly at her forearm. "I'm not goin' anywhere, so ease up on him!"

"Shirt first," she demanded, unaffected by Sam's desperate struggles.

"Dean…" John warned from a safe distance, alerting his son to the fact that he didn't have an open shot yet.

Dean knew he didn't have a choice. He gritted his teeth and carefully pulled his shirt off over his head, dropping it to the sand by his feet. He held his hands out to his sides, trying to ignore the sudden chill he felt against his skin and in his gut. "Satisfied?"

"Arms behind your head and turn 'round."

"What, are you arrestin' me or somethin'? Got a set of handcuffs I should know about?"

"He's running out of air, Dean. I advise you to act quickly."

"Alright!" He bit his tongue as he forced his arms up behind his head, fighting to block out the pain in his side as the stitches were pulled taut in his skin. Feeling like a piece of meat dangling from a hook, he then turned so that his back was facing her, his entire body tensing as soon as she was out of his view.

Sarina licked her lips hungrily at the sight of Dean's tanned, muscular back and flexed arms. She forced herself to focus on the task at hand. "Not too bright coming out here unarmed, handsome. Let me guess, Sammy didn't tell you he was planning to visit, did he?"

Now Dean understood her request. She was making sure he didn't have any weapons hidden on his person. He just hoped she didn't make him prove it any further, or she might find the silver dagger stained with dead man's blood hidden against his ankle. It wouldn't be enough to kill her, but it would certainly slow her down.

"Not so much. Probably thought I'd get jealous seein' as how you and I had such a special bonding moment last night… Can I put my arms down now?"

"No, but you can turn back around. I must admit I'm enjoying the show."

"Well, that makes one of us," Dean grumbled as he turned back around, locking eyes with his little brother, hoping to give him some comfort.

Sarina eased her chokehold on Sam like she promised and he gasped in a few ragged breaths.

"You okay, Sammy?" Dean checked automatically.

"Y-yeah," Sam stuttered out through a quivering jaw as the lightheaded feeling began to ebb. He had fought against plenty of supernatural baddies since his father began training him, but never in his short life had he gotten this close to one or felt so helpless against it. Not to mention he was terrified for his brother.

"On your knees," Sarina commanded Dean, giving Sam a rough shake when the older brother's defiant eyes found hers.

Holding the eye contact, Dean dropped heavily to his knees in the sand, ignoring the jarring that went straight through the abused muscles in his body, left over from the painful spasms of hypothermia.

"Now what? You want me to do the hokey pokey?"

"Tempting… But no. Now little Sammy gets to join in the fun."

Dean looked stricken. "What? No!" He started to lower his arms, preparing to spring forward and protect his brother at all costs.

"Down boy." She quickly pulled Sam back a step, making sure they were safely out of Dean's reach. "Get your mind out of the gutter, Dean. I'm just saying he has a part to play in our little game."

"If you hurt him, I swear to god…" Dean spat.

"I wouldn't dream of hurting my loyal guard puppy. That would be counter productive."

With a seductive smile aimed at Dean, she bent low enough to put her lips by Sam's ear and whispered soft commands no one else could catch. Dean's eyes narrowed as he watched the fight leave his brother and a glazed look came over his face.

"Don't listen to her, Sammy!" he shouted out in warning, but it was too late. Sam would only listen to Sarina now.

She turned to the two men, waiting nearby to annihilate her as soon as the opportunity presented itself. "Either throw your guns in the water, or Sammy goes for a swim."

"Can't do that," John called her bluff, tightening his grip around the trigger. The moment she let Sam go, she was dead.

"Fine. I guess we'll be going now then," she smirked and started walking backwards towards the water with Sam following obediently, oblivious to the danger he was in.

"Dad!" Dean shouted in anger once Sam had taken two steps into the water. "Do what she says!"

John and Bobby exchanged meaningful looks before coming to a mutual understanding. They reluctantly tossed their guns as she requested.

"Good choice." Sarina refocused her attention on Sam, kissing the boy on the cheek before releasing him, knowing full-well he was back under her control again. Everyone watched in confusion as Sam walked over to his discarded gun, picked it up, and aimed it at John who immediately raised his hands in a placating gesture.

"Sammy, no!" Dean shouted, terrified that his brother might actually pull the trigger, with or without the Rusalka's influence. The boy made no move to suggest that he heard the plea. Knowing it was hopeless to try and break Sam out of the spell, Dean turned his desperation to Sarina. "Please! Don't. Don't make him do this."

Sarina sauntered up to Dean and put her hands on her knees so they were face to face. "Be a good boy, and no one else needs to get hurt, got it? Sam's just here to make sure the big boys don't try to interfere."

Dean gulped as her close proximity made him feel queasy. "With what, exactly?" He leaned as far back as he could to keep her out of his personal space. So what if he looked like a terrified virgin on prom night? If anything, the big, frightened puppy dog eyes might work in his favor.

She leaned forward as well, maintaining the short distance between them. "I'm still hungry, baby. I let you go last time as a courtesy cause you're no use to me dead. Now I think it's time you returned the favor." She reached one hand up and caressed the side of his face.

Dean swallowed back the bile that was creeping up his throat. He wanted nothing more than to pull away from that icy touch, but he knew he had to play his part if any of them were going to survive. "You're right. Fair is fair."

Her fingers skimmed softly over his jaw line, then down to his broad chest. "Daddy's got you on one hell of a work out plan, doesn't he?" she purred.

"It pays to stay in shape," he grunted, trying desperately to ignore her sensual touch. "Usually…" he added under his breath.

"Well I am certainly not complaining…" She traced each abdominal muscle, enjoying how his skin trembled beneath her hand. Without warning, she latched onto his wrists, which were still up by his head, and lunged forward, instantly knocking him off balance and pinning him to the ground with her own weight.

"Oof!" The air was knocked out of his lungs as she threw her whole weight on top of him. Thank god the sand wasn't concrete or he would have one hell of a headache right now.

She continued talking, completely unfazed by their sudden change in position. "You know, I don't think you fully appreciate the situation, Deano."

"Enlighten me then," he grunted out between painful coughs, hoping she hadn't broken any of his ribs when he hit the sand.

"You hear a lot of things through the grapevine. For instance, I've been told that someone's already got a reserve on little Sammy. I'm not stupid enough to tangle with the bigwigs, so I was never going to harm a hair on that boy's head. But I counted on you playing the hero, and as no one has put a claim on your head yet, you're all mine, baby."

"Lucky me… Wait, what do you mean someone's got a res…?"

"Shhh…" She placed a cold finger against his lips, cutting him off. "Less talking, more action."

John had seen enough and decided to try his luck with Sam, unable to just stand there and watch her take advantage of his eldest once again. He took two steps forward before ducking and covering as a warning shot flew past his head.

"John, no!" Bobby grabbed the man's arm, pulling him back slowly until he was at a safe distance again.

"I had to try, Bobby!" John growled, feeling as though he needed to defend his actions.

"If you had waited a few more seconds, I would've been doin' the same thing," Bobby admitted, barely controlled anger lacing his words. "But I don't think you're on Sam's top ten list right now, so don't force his hand."

"I promised Dean. I promised him I wouldn't let her get him again."

"Dad?!" Dean tried to sit up when he heard the shot, scared as hell that he might see his father lying dead in the sand, but Sarina placed a strong hand on his chest and pushed him back down. The other hand locked tightly on his chin and forced him to face her.

She glanced over at John, making sure he was watching as she smiled wickedly and clamped her lips over Dean's, sliding the hand that was on his chest down to his sculpted hip.

John snarled, clenching his hands into fists as he imagined wrapping them around her throat.

"Don't watch, John," Bobby stated, catching John's attention.

"How can I possibly ignore what sh…!"

"Think, ya idjit! She's puttin' this show on for you! If you're not lookin', she won't get as much pleasure out of it! Now turn the hell around!"

John sighed, frustrated, but had to admit Bobby's plan made sense. He just hoped Dean didn't pay for this little stunt.

Dean squeezed his eyes shut and held his breath as her mouth descended onto his. Her grip on his chin was tight enough to bruise and it didn't feel like she was going to let up anytime soon. She bit his lower lip, drawing it into her own mouth, then lapping gently across it when it started to bleed.

The bite burned like fire, but her tongue felt like ice and Dean unintentionally let out a small groan at the mixed sensations which he quickly stifled. She broke the kiss, allowing him to draw in air. He panted harshly as his lungs protested the assault.

Sarina laughed cruelly. "Don't hold it in, handsome. I want to hear you. It's not a sin to express your feelings…" She descended on him once again, kissing her way down his neck and peppering soft kisses across his chest. His hands curled into fists behind his head and he set his jaw, trying to think of anything other than how amazing her lips felt against his skin.

She knew she was affecting him and she was enjoying it immensely. Her hand slid up from his hip and the other came down to mirror it, caressing his sides and he gasped, jerking sideways when she brushed against his wound. Unwilling to waste the opportunity, she plunged her tongue into the warm cavern of his now opened mouth and began exploring, making him want to gag.

She pressed her knuckles into his injured side and his hips bucked involuntarily off the ground. Sarina pulled back a few inches and saw the lust deep within his wide, green eyes. "Pain turns you on, huh? I can work with that…"

Dean wanted to scream for his dad to help him, for someone to shoot her before she took her explorations any further… But he was aware that he was on his own now, and he knew what needed to be done. He just hoped to hell that he'd make it through this in one piece.
