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.

Sarina licked a burning path down the center of Dean's chest until she reached his navel. She nipped at the skin just above his low-riding jeans, glancing up his body to see the inner turmoil on the boy's face as he squirmed. It was clear he wanted to resist her seduction, but she wasn't related to the succubae for nothing.

The heat from his skin was intoxicating to Sarina. She needed more. She took hold of a corner of the bandage on his side and began peeling it off slowly. Dean quickly lifted his head to see what she was doing. The fear in his eyes turned her on more than ever.

Once the bandage was fully removed, she saw that the wound had begun to bleed again due to her harsh treatment a few moments ago. The blood trickled slowly down his side and towards his back. It was too tempting to resist.

He watched in horror as her tongue darted out to lap at the escaping blood before she sealed her mouth over the wound, sucking gently as though drinking from a juice box.

His gasp quickly turned into a whimper. It wasn't so much from the pain, but from how close he was to losing what little control he still had. The icy sensation against the graze was easing the burn that had been there ever since his father had pulled the trigger. He was starting to feel lightheaded and his skin tingled.

"Shit…" Bobby mumbled, making John whirl back around against his better judgment, needing to know what was going on behind his back. He felt his anger rise when he realized what was happening.

"Damn it, Bobby, she's feeding off of him!"

"I can see that, John," he growled back, feeling as helpless as the man standing next to him.

"Why isn't he fightin' back?" The disappointment in John's voice was enough to make Bobby want to punch him.

"You mean like how you fought back when you first met her? She ain't no ordinary gal, and Dean… Well, he's Dean. What did you expect him to do?"

"I dunno, something!"

"It's too late, John. He's not in control anymore."

"We have to stop this!"

"You got any ideas, feel free to share."

John sighed in frustration. "Well, we can't get to Dean unless we take Sammy out first."

"I've noticed, but we can't get close enough to Sam without him pullin' that trigger."

"Diversionary tactics. If we split up, he can't keep the gun trained on both of us. Take the left."

"Just don't do anythin' stupid, John…" Bobby warned, knowing all of their lives would be at stake if they screwed this up. He started circling to the left as John branched off to the right.

Sarina moaned in delight as she fed, becoming stronger by the second as she weakened Dean. He felt the vibrations against his skin and dropped his head back to the sand, squeezing his eyes shut against her ministrations. No no no no no! Stay in control, you idiot!

John spared his eldest son another glance, then returned his focus to his youngest. "Somethin's not right here, Bobby."

"Gee… Where do I start?" Bobby scoffed back, inching another step closer to Sam.

"I'm serious! Look at Dean's eyes. He's not under her control like Sam. And he's terrified of her. No way would he give in that easily." And then it clicked. "He's gotta be playin' an angle, Bobby. We've got to buy him some time." Atta boy, Dean…

Sarina slid back up Dean's chest, letting her hair tickle his skin as she went, until they were face to face again. She waited until he opened his eyes, then descended towards the boy's lips for another go, and this time he met her halfway, deepening the kiss himself. Her eyes widened in surprise at first, but then she smiled wickedly. Clearly, she had won.

Dean had to force his stomach not to revolt when he tasted his own blood on her lips. His disgust helped to shake him out of the stupor he had fallen into and reminded him of his plan. Like the Striga, Rusalkas were most vulnerable when they were feeding. Though the thought terrified him, he had to let her take what she wanted. He knew he would be weakened in the process, but he'd have to hang on and pray that the others would be able to stop her for good.

As she started pulling back again, he tried to move his hands out from underneath his head, but she gripped his wrists tightly, preventing them from moving. Damn it…

"What do you think you're doing, Dean?" she asked softly against his cheek before moving forward and catching his earlobe between her teeth.

Dean swallowed hard. "Just… Just wanted to hold you is all."

"Is that so?" She rocked her hips against his slowly while trying to read his face for any underlying deception.

Unable to verbally respond without making a sound he would regret, he settled for nodding his head, then waited with bated breath for her acquiescence.

She ran her hands gently over his exposed sides again, debating her options. He shivered beneath her touch and bit his bottom lip. She liked having him so defenseless, but she knew it would torture John even more if she allowed Dean to let his lust take over. "Okay, but one wrong move, and daddy gets a new hole in his head, courtesy of Sammy."

Sarina glanced over to the two men to rub her success in John's face and felt her anger rise at the fact that both men were trying to outsmart the youngest Winchester rather than paying attention to her antics.

"You're cheating, Johnny!" she called across the sand. "And you know I don't like cheaters." John ignored her, keeping his focus on Sam instead.

The boy kept swinging the gun back and forth between Bobby and his father, warning them both back, but as one froze, the other continued to advance. They were closer, but not quite close enough to take the gun from Sam yet.

Sarina rolled her eyes. "Sammy, be a dear and shoot your fa…"

Dean reached up quickly and pulled Sarina's face back towards his, controlling his disgust and fear enough to give her the most passionate kiss he could muster. She was tense at first, unsure if she wanted to take her eyes off of John just yet, but when Dean deepened the kiss, she suddenly didn't give a damn what the father was up to. She only had eyes for Dean.

While returning the kiss, her hands moved south over his abs until she found the top of his jeans and curled her fingers around the waistband of the fabric, pulling him flush against her. He gasped, breaking the kiss, and when she looked into his beautiful green eyes, all she could see was lust. Of course, that was only because that's what Dean wanted her to see. After all, he was very skilled at burying his emotions.

As he stared into her glassy brown eyes, he could see his father and Bobby in the background, working to distract Sam. If they could get control of the gun, then he'd know they were all safe and he'd be able to initiate the second half of his plan. But until that happened, he'd have to keep her preoccupied.

"Are you trying to distract me, Dean, or did you really miss me?" she purred, peppering his neck with soft kisses and following them with painful nips that she soothed with her icy tongue.

"You're the most beautiful woman I've ever seen…" Dean forced out as his heart began pounding in his chest. Her fingers were now undoing his jeans with practiced ease.

"Baby, you're in for a treat." As her hand started sliding underneath his boxers, he grasped her wrist tightly.

"Wait!"

"For what exactly?" She sounded annoyed now.

"I… I'm better on top." With more strength than he realized he had left, Dean flipped their positions, pinning her beneath himself.

She was surprised, but even more excited now. "Love a man who takes control."

"Yeah?" He was kneeling above her, trying to keep his dad's position in his periphery.

"Oh, yeah…" She reached up, took hold of his hips, and pulled him down so they were flush against each other again.

He grinded against her pelvis as his hand reached up to cup her left breast. He leant forward and captured her lips with his own again, distracting her as he slowly reached his right hand back towards his ankle.

She was trying to slide his jeans down his waist, but he kept his knees spread far enough that the fabric was too tight. She settled for sliding her hands up and down his clothed thighs.

He could feel her feeding off of his lust once again. Just a few more inches till his knife was within reach… Bingo!

"You know, normally I don't risk letting my dinner go when I'm still hungry. I had every intention of drowning you while your father suffered on the beach, but I knew you'd be worth the wait, handsome…"

Dean smirked. "Yeah, well… You should've killed me when you had the chance, bitch."

John threw himself forward, tackling Sammy to the ground and wrestling the gun from him. The boy let off another shot in surprise, capturing Sarina's attention.

Without wasting time, Dean pulled the knife from his boot and plunged it into her chest. All his mixed emotions that he had been bottling up since this whole mess started fueled his strength and he rammed the weapon in all the way to the hilt, panting with the relief from finally having her hands off of him.

Sarina let out a blood-curdling scream as the knife tore into her icy flesh. Needless to say, she was furious at having been duped by the Winchesters yet again. Enough was enough. Playtime was over now.

As Sam continued to struggle against his father's weight, John was forced to knock him out with a well-placed sucker punch. "Sorry, Sammy." He patted the boy gently on the back and turned Sam's gun onto the Rusalka.

Once he knew the situation had been handled, Bobby splashed out into the water to retrieve their discarded weapons so that they could help Dean, but he wasn't quite fast enough.

Sarina reached up, furiously, and wrapped her clawed hand around Dean's throat, squeezing as tightly as she could. Luckily for Dean, she was weakened by all the injuries she had sustained at his family's hands. However, that just brought her supernatural strength down a few notches, placing it just above normal for a human being. And with Dean's own injuries, he lacked the strength to break her grip.

"I could have made this good for both of us, Dean, but you had to go and piss me off, didn't you? I am going to feed, baby, with or without your consent."

She kept one hand around his throat and with the other, she slammed a fist into his stomach, knocking the wind forcefully from his lungs again. He was starting to see black spots and feel dizzy.

She easily flipped them over so that she was back on top, then pulled the knife from her chest and held it to Dean's throat. With her other hand, she started pulling at the boy's jeans, desperate to get at the prize hidden beneath them.

"No…" Dean croaked out, trying to push her hands away again, but she pressed the knife deeper into his neck, piercing the skin.

"No more protests, handsome. Just submit."
