Day 10: Urban legend (AU, Seth/Kate)

SMUT AND VIOLENCE WARNING

This is the first prompt I had to swap out: the original was 'fall or Halloween blog feature'; I picked 'urban legend' as a substitute. I'd originally had a vague idea of Seth and Kate making out in a car to lure out a serial killer copying the Hookman (or something along those lines anyway), but, well... this sort of sprouted instead. All things considered, 'slasher movie' is probably more appropriate, but oh well.

In the interests of CYA, there are implications of Kate/Seth/Richie, for the many of you who are into that. I don't think it would work very well myself, especially post season 1, but it sort of just appeared in this.

Also, I am not kidding; this is where I earn the M rating. SMUT AND BLOODY MURDER LIE AHEAD.

When Kate had accepted a counsellor position at Camp Sunnydale, she'd just wanted a summer job that would get her out of Bethel. A chance to spread her wings a little, be her own person, and get to know some new people who didn't automatically attach the title 'Pastor Fuller's daughter' or even 'Scott's big sister' to her name. That plan had taken a near-fatal blow when her ex-boyfriend had turned up at the same camp. One of the reasons she'd wanted to leave Bethel for awhile was to get away from all of the people asking what had gone wrong, when Kyle was such a sweet boy, and wasn't there a chance that they could fix things?

Yes, Kyle was sweet. But Kate had discovered that she wasn't.

She tried to be a good person, and hoped she succeeded. But all it had taken was spending one day alone with the criminally handsome and charismatic Camp Manager, and Kate's entire view of herself had flipped upside-down like a ship in the ocean.

If it hadn't been for that day, Kate would have simply enjoyed her teenage crush on Seth Gecko, barely even imagining – let alone daring - to actually say or do anything about it. But that one day they'd spent working alone together, with all the other staff busy at the other end of the camp or in town, had made Kate's instant case of lust evolve into something far deeper. It was all the small glimpses she'd received into Seth's mind and heart. The bone-deep mischievous streak, the love of winning, and putting one over on the foolish – even the hints she'd caught of a darker side to him, that Seth would have no compunction in breaking the law if the reason was good enough. But it was probably how he acted with his younger brother – Richie had joined them for lunch – that sealed the deal.

As an older sibling herself, Kate had a special appreciation of the fact that Seth was an excellent big brother. It was easy to see that he didn't actually like the forest or the outdoors all that much, but he'd taken the job at Camp Sunnydale for Richie. Kate sensed instinctively from that first lunchtime that Richie was a gifted, but tortured soul. Seth had admitted to her some time ago that he'd brought Richie out here in order to give him a measure of peace that he hadn't been able to find anywhere else.

Some of the other campers – even counsellors - found Richie creepy, or even scary. Not Kate. She was secure in the fact that Richie liked her very much. Richie was the one who had given her the first hint that Seth might just return her feelings, and since then he'd helped cover for her and Seth on a regular basis. Kate owed Richie a lot; she was crazy in love – and in lust – but not so crazy that she didn't realise that her love affair with Seth had to be kept absolutely secret.

Kate knew exactly how badly she was behaving. Her parents would be aghast if they knew what she was doing here at Camp Sunnydale; fornicating outside marriage - with a man ten years her senior! She didn't care. Seth Gecko wasn't a bad man, but he was a wicked man, and he made her feel like a woman. From the very first time she saw him, he stirred desires in her that she hadn't realised she possessed. Her body came to life underneath his touch. Three weeks after they'd met, Seth had kissed her for the first time. Two weeks after that, they'd had sex for the first time after a naked moonlight swim. Under Seth's expert guidance, Kate had swiftly learned to not only embrace, but thoroughly enjoy her own sexual needs.

Kate knew it was stupid to come out here into the forest, especially in the dark. It was completely obvious that Kyle was just making up stupid stories about some guy in a coverall and a mask stalking the woods to punish horny teenagers – her ex had started the childish game the same day Kate first realised that her feelings for the drop-dead-gorgeous camp manager might be requited. But still, the local Sheriff had just confirmed on the news that several teenagers had gone missing from the valley in the last week. More to the point, Seth had his own cabin with a real, queen-sized bed. Surely he could ask his brother to bunk elsewhere for one night? Kate knew Richie wouldn't mind – unlike Seth, he really enjoyed hunting and camping, and he slept out in the woods on a regular basis anyway.

But when Seth had met her behind the main hall, he'd just taken her hand and brought her here, to this small clearing with just enough light for her to clearly see every mouth-wateringly sexy inch of his form.

Kate leaned back against the trunk of a tree, and gripped Seth's shoulders to steady herself. It had only taken a few minutes to walk here, but she could already feel the damp heat between her legs, fuelled by her fantasies of what Seth was about to do to her. Seth hurriedly stripped off his tight T-shirt, and Kate couldn't resist the urge to trace several of the black flames tattooed on his arm with her fingertips. Seth shivered in reaction, and Kate felt her blood running hotter. Her nipples were already hard, and they rasped almost painfully against the rough cloth of her plaid shirt. Even in the dark of the woods, she was so close to Seth that she could see the lewd smirk spread across his face.

"Preacher's daughter is hot for some bad boy, huh?"

Kate raised her chin proudly. "No. I'm hot for a man. One who's very good at being bad."

She might be disgracefully lustful now, but she refused to feel ashamed about it.

The smirk became a genuine smile, and Kate found it even harder to breathe for a second. "Good for you, Kate." The smile became tinged with danger, as he added, "Better for me... because I'm not interested in teenage girls, either. I want a woman who knows what she wants, and can push back as good as I give it to her."

The weak moonlight glinted off steel, and Kate's breath caught for an entirely different reason as Seth raised the knife. Her heart pounded as the blade lowered to her chest, and she gasped with each movement – with each button being cut from her shirt.

When her shirt hung open completely, baring her breasts to his gaze, Seth slipped the Swiss Army knife back into his back pocket, and chuckled. "No bra?"

Kate licked her lips and fought back her blush. "I didn't want to have any more layers between us than I absolutely had to."

"Didn't want any delays for the main event, huh?"

Daringly, Kate reached for the button of Seth's jeans, and told him, "No, I didn't. The sooner I can feel you inside me, the better."

Seth gave that dark, wicked chuckle again, and pulled down her shorts and panties in one shot. Kate shimmied out of her lower clothing even as she attacked Seth's jeans, so that she wore nothing but her useless shirt and sneakers. Kate pressed her back against the tree, the cloth of her shirt protecting her from the bark, and bit her lip as she reached out to her lover.

"Yes, that's it sweetheart," Seth hissed in her ear. He reached down to hook his hand under her knee, and Kate wrapped her leg around his hips. "Open your legs for me, honey, welcome me inside."

Kate moaned as Seth thrust hard, pushing as deep as he could with the first stroke – he always did that, never took it easy on her except for the night he'd taken her virginity. She loved the way he didn't hold back, that Seth always fucked her like she was his equal.

"Shit, Katie," Seth growled in her ear. "I love how tight you are – I love how wet you are for me."

"Well, I love how you turn me on, how you always make sure I am," Kate panted. "I love how you fill me up."

Kate and Seth were too focused on each other to notice the blank, white face watching them from the shadows. Beneath his mask, the one who thought of himself as the Slayer of the Sinful ground his teeth as he waited to strike, forcing himself to wait until the pair in front of him were so lost in their disgusting rut that he could attack without caution – the Slayer had had no trouble with the pimpled, skinny teenage boys and girls that he'd struck down so far, but Seth Gecko was a man, strong and muscled and a far more experienced fighter than the Slayer.

The girl flung her arms around Gecko's neck and gave a soft cry, her body thrashing in her lover's strong hold as she climaxed.

The Slayer tightened his grip on his axe.

The razor-sharp steel bit deep, so smoothly that it was several heartbeats before the mortal wound was felt.

The axe dropped to the ground, with only a tiny crackle from the bed of leaves, and the Slayer turned slowly, eyes wide. Only to find himself almost toe to toe with another, equally pale face, eyes hidden as the lenses of his glasses caught the moonlight and flashed menacingly.

A second knife slid like butter between the Slayer's ribs, and with both lungs punctured he couldn't made a sound.

"This is my territory," hissed Richie Gecko.

Ritchie waited until the pitiful amateur collapsed to the ground, before he casually stepped over the new corpse and moved into a better position to watch Seth and Kate's lovemaking.

Ritchie smoothed his hand down his fly, flat and undisturbed as always, and smiled in contentment. As a result of the abuse their father had heaped on them as children, and what it had forced Richie to do in order to stop it, Richie's body couldn't react sexually. His resulting frustration and anger had led to him honing his killing skills while just a teenager. Fortunately, he'd only had to kill a handful of times before he'd found a better, safer way. On a trip to Mexico in mid-adolescence, he'd met a priestess of the old Mayan gods who had taught him to unlock the true power of his mind – and he'd found that his unresponsive body could feel sexual pleasure after all. He just needed to experience it through the unique, intense bond he shared with his semi-twin.

Seth was now pounding hard into his lover, his own orgasm quickly approaching, and Richie clinically admired the perfection of Kate's moonlit breasts as they bounced violently, shockwaves rippling through her whole body from the force of Seth's fucking.

Richie took a deep, slow, breath, and wrapped his fingers around a convenient tree branch, gripping hard. The pleasure Seth was channelling through their bond was more intense than anything he'd ever fed Richie before – so intense that Richie could almost feel his dead manhood twitch.

But then, it was only to be expected. Seth had had many women over the years, partly because he was always careful to make sure he gave at least equal pleasure as he received. But this woman was different; Kate was the last woman, the lover who had already ruined him for all others.

Ritchie had always been able to see truths and connections that were hidden from the eyes of others; he had long since accepted it as compensation for his condition. His training in Mexico had increased it a hundredfold, turning glimpses into full-colour visions. So the first time he met Kate Fuller, he'd known she was the missing piece of their family. Wife, sister, and lover - this was the one he and Seth had both been waiting for. Gentle enough to heal them both, strong enough to stand tall against the violent havoc their tempers sometimes wreaked. Understanding enough to accept their unusual bond, and loving enough to not only fit in the spaces between them but to make her own space as well.

Seth's psychic senses were almost as dead as Richie's sexuality, but the first time he'd laid eyes on Kate, he realised he had to have her. The first day they spent together alone... Seth told her the real story behind his tattoo without even thinking about it. The Gecko brothers had planned the seduction of Kate Fuller together, Richie's psychic insight coupled with Seth's seductive physicality.

Richie's whole body froze, taken by surprise as the kickback of Seth's climax washed through him, barely able to breathe.

As he watched Seth and Kate dress – Kate self-consciously clutching the front of her shirt closed – Richie started arranging and re-arranging the pieces of his latest plan in his mind.

Luckily, Kate would turn eighteen by the end of the summer; even if her parents objected to her union with Seth (and Richie was fair enough to understand why they probably would) the Fullers couldn't actually take Kate away from them. But Kate's happiness was now as important to Richie as Seth's was. Kate adored her parents, and would be saddened by their disapproval - not to mention, she would most certainly want to be married in their church. But then, Vegas hadn't worked out very well for Seth last time anyway.

Following Seth and Kate back to camp at a discreet distance, Richie made a mental note to come back later to dispose of the wannabe's remains, then turned his mind back to the problem of persuading the Fullers to give their blessing to Seth marrying Kate next summer.

Richie knew that June was the traditional month for weddings; but he thought Kate would be most beautiful as an August bride.

This AU's sort of snuck up on me, but I think I've got some more play left in it. So now I'm wondering – I've got one or two other prompts I'll need to swap out. Should I write more of those particular prompts in this particular AU?
