Derek's mind was racing, his heart was beating furiously in his chest and he couldn't begin to control it. His palms were sweating and he curled his fists, making his nails bite into his palms. How had he gotten himself into this situation? His arms were spread eagle, chained above him and the cold chill from the steely bars pressing against his skin couldn't stop the sweat from dripping down his body. How the fuck had he gotten himself into this situation? He'd grown too attached to Scott. That's what happened. Had told the boy to run, while he stayed to fight the hunters off alone. A fools errand, but he'd done it nonetheless. He allowed his head to roll back, and leaned heavily against the bars supporting him. He hadn't planned on being captured. He'd expected Kate to shoot him dead in the heart... with a snide comment to grace his last breaths. He shouldn't have underestimated her. Attempted to predict her. He knew better than that, and yet here he was, having fallen into her devised trap once more.

He gulped hard, his tongue heavy and thick in his mouth from lack of water.

He should have known better. Kate loved to toy with him too much to let him off with a quick death. She would tear out his bitter heart until the end.

Determined steps echoed down the hallway and alerted him to company. Despite how sore and worn he had become over the several hours of torture he'd had to endure earlier, he couldn't mistake those steps. Kate was coming. To visit him, to berate him, drag him into unforgiving darkness... his own living nightmares. He shifted in his cool confines, straightening and lifting his head stubbornly. He wouldn't allow her to see the effect she'd had on him.

Kate seemed to glide around the corner and right into sight. She caught his eyes and he immediately shifted his gaze to the wall beside him. He didn't want to look at her.

"Oh sweetie," Kate purred, "have you been waiting for me?"

Derek ignored her and stared fixedly at the wall.

"Mmm, of course of course, let's not get ahead of ourselves here. We've only just begun our little reunion." Kate continued, sauntering over to the table where the shock device lay prepped, and slid onto its edge."Tell me, Derek, how would you like to consummate our reunion? Start from the beginning?" she teased, "Relive it step by heated step?"

Derek couldn't stop his gaze from flickering over to her at that. If she was suggesting the times they'd fucked in the past and repeating them... he'd fucking kill her. He didn't care how chained up or physically worn he was, if she touched him...

Kate's glinting eyes seemed to catch his thoughts and she smiled in amusement. Derek quickly looked back to the wall. She slipped off the table and causally walked closer to him, taunting, "Oh sweetie, don't tell me you've missed me all these years?"

The muscle in Derek's jaw visibly jumped as he ground his teeth together.

"The way I made you feel? With something as little as a caress?" She baited, sliding a few fingers down the side of his sweating chest. A smirk graced her features as she watched his nipples begin to pebble.

Derek turned his head further to the side, glaring heatedly at the bricks on the wall lining the bars he was chained to. He wouldn't let her get to him, not again, and slowly, steadily, began to count, brick by brick up the wall.

"My my, mighty reactive aren't we?" Kate whispered, leaning closer.

Four... five... Derek counted in his head. Breathe. Six, seven. Breathe. Eight, nine. Breathe. Derek continued the mantra.

Kate ran her fingers back up the side of his chest and down again. Goosebumps began to spread up Derek's chest and down his arms.

...fourteen... Derek continued in his head.

"Look at how bad your body craves it!" Kate exclaimed, "One would think you haven't been touched in months!"

Derek's jaw tightened and his eyes narrowed further at the wall as he desperately tried to focus on counting. Sixteen?... was it?

Kate clamored on, "Oh no... oh no, no, no, no! Don't tell me you haven't gotten any since I last saw you?"

She paused, realization dawning on her as Derek's eyes shut tight.

Kate's head reared back and she laughed brightly, "You haven't! You've been celibate for what... six years?"

Derek fumbled to count another brick. Where was he? Where was he!

"Don't tell me the big bad werewolf hunter scared the pussy cat away from intimacy, did she?" Kate crooned at him.

Derek's eyebrows dipped low, hooding his eyes as he glared at the wall. I hate her. I hate her. I fucking hate her! His mind ranted.

Kate then took both hands and ran her fingers hard down both sides of his body, delighted to see Derek's chest move towards her in reaction. Her fingers then crawled up his abdomen and to the lining of his chest, fanning out to cover each pectoral, palms deftly covering each nipple. Derek grit his teeth hard in anticipation. What was she doing? Her fingers then came together at each nipple and began a delicate process of plucking at them, easing them into perky awareness. Derek's eyebrows knit together as his nostrils flared. If she even tried... Kate flicked his left nipple and he couldn't stop the reflex of his body as if curled backwards, his fists clenching hard as he cut off the groan threatening to escape his throat and swallowed it thickly. Kate's wicked grin only grew as she continued to flick at his nipples, enjoying the way the wiry muscles in his shoulders shifted in response.

"My my," Kate continued in delight, "just look at the way your dick's risen!"

Derek's teeth ground harder as he fought off the heat rising in him. He could feel the tell-tale signs of arousal as his breathing came in short, hard pants and the heat pooling in his abdomen began to slither down into his dick and beat it into growing. Distress swept through him as he attempted to control himself, forcing his breath into a smoother rhythm and clenching his abs to stop the warm boiling inside him from continuing. But he was failing, miserably, and each flick to his nipples cruelly reminded him of it as it caused coils of heat to shoot down into his groin and beat to the rhythm of his pulse, which only raced harder in reaction.

"Its almost as if..." Kate mulled out loud, looking questioningly up at her prisoner held prone before her, "almost as if you haven't came in weeks."

Derek's eyes flashed towards hers, gazing at her with an unwilling vulnerability. She eagerly took the opportunity to rove into those green depths and grabbed what she wanted.

No. No, he hadn't been with anyone since her. And no, he couldn't bare to touch himself after her either. He'd tried to bring some semblance of his former life into his new one, the one without his family, but he'd failed each and every time. After the fire... after Kate had revealed her dirty secret to him, deliberately gloated in his face, him and Laura had ran. Laura never knew how hunters had found out where they resided or who exactly had burned down their home, but she was young and had followed his lead.

But even in another state, a new town, a new house... Kate's face had burned itself into his subconscious and threatened never to leave. Every time he closed his eyes he saw her standing before him with a devilish smile on her face; and his heart would call out to her, plead for some sort of understanding into why she'd ardently decimated his family.

Despite his best efforts to rid himself of her, she plagued his dreams at night. Touching him, fucking him hard into the sheets as she rode on top of him. And no matter what he did, every morning he'd wake up with an erection as hard as steel and eager for release. He'd close his eyes and think of models or girls he'd thought of before he met Kate. But each and every time his mind would drift back to her and he couldn't take it. The thought of touching himself to her, bringing himself to orgasm with her face and body in mind after everything she'd done to him, destroyed him. And so he'd stop, never attaining release. Until weeks later, the build-up had finally gotten to him and one morning he'd grabbed himself and brought himself to a quick and hard release, thinking of nothing but her. Kate. Kate's hand's sliding down his chest, Kate's tongue licking up his shaft, Kate's hands gripping his thighs and her breath ghosting at the tip of his erection until he begged for release. And as his release set upon him and he'd thoroughly enjoyed writhing in the rapture of it, the sated feeling that followed it was short-livid and followed by a deepening hole in his chest. A devastating emptiness that spread to his stomach and seemed to echo into his limbs, making him tremble. He'd ended up puking shortly after. The guilt of orgasming to the girl who'd brutally burned his family alive in mirth clawed at his insides for months. For months he'd berated himself, detested looking in the mirror... even holding himself to urinate had made him cringe. He'd finally found that exercising, pushing himself to his limits and back again released the tension in his tightly-wound up body. And gradually the ripping guilt ebbed, as day by day he forced his body to find release through sweat and exercise instead of his hand or another's body.

Kate snickered at him, "Oh you wretched thing. Your part in your family's death's really got to you, didn't it?"

Derek's head snapped toward her, eyes blazing, "My part? My part! You murdered them!" he couldn't help the way his voice rose in consternation.

"And you," Kate whispered, her hands slipping down his chest to rest along his lower abs as she raised herself against him, "led me right to them."

Derek's lip curled back as his fangs elongated and a deep growl resonated from within his chest.

"Yes sweetie, you, despite all the warnings still fell for me and revealed your darkest secrets. The cursed truth of your family; how your body pitifully forms into that of a wolfs," Kate laughed as Derek's growling rose in volume, "You didn't just trust your life in my hands, you entrusted your entire family's! Threw them all down with you!"

Derek snapped at her, fangs desperate to rip into her flesh.

"Rather careless of you I might add," Kate added in after thought and dropped down, kissing her way across his chest and along his abdomen. Her hands came to his pants and she slipped the tips of her fingers in, undoing the button with a quick tug.

Derek snarled unabashedly, fists clenching as he began to wrestle against his restraints. Pulling heavily on them, cutting into his flesh as he tried desperately to wring his body out of it's entrapment.

Derek's ineffective efforts only seemed to spur Kate forward as she tugged Derek's pants and boxers down to his knees, amusement lacing her voice as she spoke, "Don't bother sweetie, you're not getting out of those. Though you know that... always enjoyed the fight, didn't you Derek?"

Kate leaned forward and ran her tongue up his inner thigh.

Derek yanked against his chains harder, but they only rattled in response as blood began to line his bindings.

"Always wanted me to force you into submission," Kate goaded, fingers climbing up the back of his thighs as she began to lathe the lining of his hip bone with her tongue.

"No. No!" Derek shouted, struggling harder against unforgiving restraints, blood seeping out and oozing down his forearms.

Kate chuckled, "Oh yes you did sweetie. Loved to have me take control of the situation, of you. Your body. That's why you told me the truth about your family... because you wanted another to control the wild beast within you. Because being a werewolf is tiring, isn't it sweetie? Having to control your every reaction day in and day out is exhausting, isn't it? You wanted another to control it, you, and it cost you everything."

Kate began to lick teasingly around the base of Derek's dick.

Derek grit his teeth and dropped his head back, banging it against the bars. She was right. She was always right. Handling the wolf inside him was draining and in high school everything had been so much more extreme, heightened with puberty. Any mild irritant flipped a switch inside of him and it had been so hard to constrain it. Still was. He'd gotten himself into so much trouble time and time again, regardless of his best efforts to reign in his wolf. He'd just... just wanted a break. A break from having to do it all himself for a second. Just a second. But it hadn't mattered in the end. Because the wolf still resided within him and his family had paid with their lives for those handful of seconds. He was the one who'd put them at risk. He was the one responsible for it.

Grabbing Derek's sack in her right hand, Kate began to gently roll his balls as her tongue moved up to lick at the lining of Derek's hip bone once more.

Derek's dick was throbbing for attention and he could no longer ignore it. He couldn't help the way he quivered in Kate's hands or the way his abs spasmed when she honed in on a particular spot. Derek felt his heart beat faster and his body begin to heat into a slow but sure burn. His eyes scrunched close as his chest came forward and his head fell back more, revealing the corded muscles of his neck. He swallowed hard. Kate began to suckle her way back down his hip, towards the base of his dick. Derek's abs tightened on him further, his insides wanton for more, as he breathed in deeply through his nose, his lungs eager for oxygen.

"Say it," Kate murmured against his corded erection.

Derek worked his jaw back and forth, not tempted enough to speak out.

Kate's tongue flicked out suddenly against the head of his dick and Derek's breath hitched at the unexpectedness of it. Her tongue darted out again and Derek shook his head, clenching and unclenching his fists.

"Oooh, it's starting to bead out. You must really be feeling it now sweetie," Kate cooed out, her fingers beginning to gently bounce Derek's balls.

Derek breathed harshly out his nose and rammed his head against the bars, desperate to keep his voice at bay.

Kate immediately sucked the tip of Derek's dick into her mouth and swirled the tip with her tongue.

"Stop," Derek whispered tightly.

Kate's suckling only increased as her tongue then went to flick against the edge of the head of his dick.

"Stop!" Derek's strangled-voice sounded out.

Kate sucked on the tip, leaning back incrementally until Derek's dick slipped out of her mouth.

"Say it," Kate repeated, her voice steady, eyes wandering up his twitching abs and sweating chest to look up at him.

Derek tightened his fists, feeling the bite of his nails before loosening them slowly and unclenching his jaw. His lips parted as he whispered, "Please."

"Again," Kate's voice ordered out.

Pausing, Derek exhaled out heavily through his nose. He sagged against the bars and his head dropped forward. His eyes opened and met Kate's. How could he be doing this to himself? Again.

"Please," Derek begged.

Kate looked steadily into Derek's green eyes. Reveling in how easily she had manipulated him into dropping his guard for her again, even after all that she'd done to him. He was so vulnerable to her and it couldn't have satisfied her more. Briefly she wondered if leaving him hard and wanton after pleading for it would destroy him more than coming, and that's when it hit her and she realized it would.

The twinkle in Kate's eyes made Derek's eyebrow rise in question, but all was soon forgotten as Kate leaned back over his dick and sucked the whole of him down. Her right hand now cupped his balls and rubbed them back and forth against each other as she suckled up and down the length of his dick.

The heat that enveloped him rejuvenated the boiling inside him and began to coil up his dick. His fists tightened and he had a desperate desire to grasp onto something and hold fast. Kate's movements below quickened and a particular flick at the tip of his dick on her way up made him release a muted groan. He was close. Almost there.

"Please," Derek murmured, his chest thrusting out and his head falling back.

"Please," Derek repeated, louder, as his abdomen tightened and sweat slid down the back of his thighs.

"Please!" Derek called out as the coiling became unbearable and all he could feel was the warmth of Kate's mouth around him and the way his body bent back as if strung. He couldn't take it any more!

Suddenly the warmth seemed to evaporate into the air and all Derek could feel was a chill encircling his dick.

A soft, disgruntled sound left Derek's lips as his body tightened in need once more and he felt the hard pulse of his dick one, two, three times before beginning to ebb. Derek hesitantly opened his eyes and gazed forward. Kate was crouched in front of him with a grin on her face. Derek's jaw tightened and his nostrils flared. She'd been playing a game with him. Grabbing the back of his jeans and boxers, she dragged them up his thighs and around his butt. Leaning forward Kate abruptly licked the pre-cum off the tip of Derek's dick and Derek's head snapped back as a gasp escaped him. Kate then methodically tucked his dick back into his boxers and zipped up and buttoned his jeans. By the time she was standing Derek had turned his face away, eyes gleaming with hurt.

"Aww sweetie, you didn't actually think you'd get what you wanted, did you?" Kate mockingly soothed.

Derek's teeth ground together and his brows drew inward, but his gaze remained steadily on the wall.

"Or did you really think I'd get you off like old times?" Kate taunted, "You do realize that I was using you then too, don't you?"

Derek was beginning to blink faster and his teeth creaked as he clenched them harder.

"Oh no," Kate murmured, fascination lighting her tone, "you don't actually still love me, do you?"

The heat in Derek's chest rose with the increasing pace of his beating heart. The muscle of his jaw jumped as his nose scrunched.

"You do!" Kate cackled, amazement overwhelming her, "After I killed you family? You've got to be kidding me!"

"Why are you doing this?" Derek asked, voice thick.

Reaching up, Kate firmly grabbed Derek's chin and turned it towards her. With his eyes still trained to the wall, Kate ordered, "Look at me." Kate watched his green eyes trail to hers until they met and drew strength from the pain flowing in their depths. "Because you're a beast," she stated.

Derek felt a cold ice worm its way through his stomach and weave up into his heart.

Slipping forward her lips ghosted over his ear as she continued, "and all beasts need to be tamed."

Derek lungs seemed to constrict as her words swept through him.

Dropping back, Kate released his chin and roved over his lowered eyes and forlorn features. "Until later," she cooed and turned to leave.

An overwhelmingly hollow heat racked up Derek's chest and slithered up his neck. As his eyes lifted to follow her out the room, a tear slipped unbeknownst down his cheek.
