Luuka: this story is done! Thank you for reading!

Free! needs more horror AUs- it does. This was Luuka's contribution and I tried to balance 'messed up' and 'sweet,' so tell me how that turned out. (laughs) At any rate, it's over.

If you've stuck with me, I'm impressed and proud of myself for finishing this! Thank you so much for the feedback and I hope you've enjoyed the story, I'm happy/surprised at all of the positive comments because I didn't expect it in a horror. I love horror/romances to death so I'm glad other people do, too.

This is the final instalment!

5 years later:

Yoshito stumbled through a field as the night air ruffled his coat collar, causing it to bounce back and brush against his cheek. Sweetcorn plants snapped beneath him as he followed a figure through the thickening twilight- panting to keep up with the speed at which it walked, a low moon hanging above them in the sky.

The man in front of Yoshito- Rin- he'd met at a nightclub where Rin had managed to transfix him: from a distance he'd seemed like just another loser, yet up close Rin was alluring... so much that it seemed inhuman. He was barely legal- perhaps a few months from his eighteenth birthday- and Yoshito didn't usually go for the younger ones, but there was something about Rin: he hadn't been able to walk away. Maybe that was why he'd climbed into Rin's car without a second thought. Maybe that was why he'd let Rin drive for three hours, away from the city into the middle of nowhere, through a field then into an abandoned pipe-

'Uh, hey... you sure you live all the way out here?'

Rin opened the drains lid and smiled.

'You're coming, right?'

If Yoshito had been able to look back, he wouldn't have known why he'd gone into the drain- he would have said that he was brainwashed, because indeed, it was possible that he could have been; in that moment, he'd felt prepared to do anything Rin had asked him.

'Wh-where are we going, exactly?'

He wasn't granted with a response. Water dripped and their footsteps made splashes as they wandered through a labyrinth of pipes, deeper and deeper underground until eventually, they arrived in a hall... and Yoshito's breath caught in his chest.

There was a granite block in the middle of the room and around it bodies lay in a pile, broken and bent back at different angles- some of their faces fixed into dying screams- half eaten, tangled in each other as they decayed, and yet none of them mattered... because there was something far more breath-taking sitting atop of them.

Rin grabbed Yoshito by the scuff of his neck and pushed him down onto his knees before lowering down to kneel himself, dropping his red eyes to the floor. Yoshito couldn't help but steal a glance back up to the top of the pile once again: if he'd considered Rin to be enrapturing, then the being before him was something else.

His chin rested on his fingers as he surveyed them both, cold eyes narrowing as his gaze fell past the bones at his feet, onto Yoshito and Rin; the blue in his irises appeared to shine, as he peered out from beneath a dark fringe. His body was smoothly muscled- one long leg spread apart from the other- his slender hips rushing down into- what Yoshito imaged would be- a round ass with a tight, hot passageway that would wrap around and caress his own aching, throbbing length. He wanted to feel that more than anything. Looking up at the man above him caused Yoshito to feel so much desire that it was physically painful to bear... he gazed up, breath wavering uncontrollably as he spoke:

'Y-you're beautiful.'

Suddenly he was pinned to the floor, two red eyes flaring as Rin's hands squeezed his neck.

'Know your place,' Rin snarled in one breathe. The dark-haired man spoke.

'You took too long,' he said down to Rin, in a voice that was impossibly soft- it reminded Yoshito of clear water babbling along a meadow stream in the spring.

Rin dropped his head.

'I wanted to bring him back for you alive. I-I try not to get noticed...'

'I was waiting.'

The male stripped away his shirt to reveal the inward dip of his stomach, his slim chest pale in the dark of the room. He walked down the steps of the granite block- past the piles bodies that surrounded him- every lift of his legs seeming sensual until he stopped before Rin. He was actually shorter than the other man by a fraction, his bones a little more slender…

Then, as if Yoshito were not present- or as if he simply did not matter- the two of them begun to kiss.

'Haru...'

Fear paralysed Yoshito as he watched from the floor. He knew the two men in front of him had implied he could have been brought here dead, but he was unable to move away- arousal built as he witnessed them embracing, a moan escaping his lips. Haru evidently heard the sound because he turned, blue eyes gazing down at Yoshito… the intensity of his stare held the same effect as someone squeezing his cock- he no longer knew what he wanted.

'You don't have to be afraid,' Haru told him. 'Death doesn't hurt. I know.'

During that moment, Yoshito felt calm- he didn't even realise it when Haru's fingers closed around his windpipe and tore it out, exposing the white of bone. A stream of red flowed steadily from the breach, his head dangling limply to one side… tentatively, Haru removed his hand, drawing himself up.

'Haru...' Rin moved closer. 'You've got blood on your hands...'

'It's wasteful.'

Immediately Rin lifted Haru's palm and begun to lick the blood from it, lapping up all of the red to leave Haru's skin white and pure again, sucking on his fingers- breathing heavily as he took his time to clean the tips.

'Is it good?' Haru asked.

'Better when it's on your body. Haru... I need...'

'Then come to me,' Haru said simply. 'And I'll give you what you want.'

Holding his hand, Haru brought Rin to a double mattress and laid him down with a soft thump. They kissed passionately, ripping each other's clothes from their backs.

Normally, Rin waited for Haru to command him but now the dark-haired male's legs were spread, his breathing making soft sounds as Rin climbed atop his body. He allowed Rin to bite into his throat, leaving deep, crimson marks which healed over instantly, leaving Haru's skin creamy and untouched so that Rin could bite him over and over, yet not even blemish him slightly.

'Harder,' Haru commanded as Rin bit. 'I want it-'

Naked, Haru looked more desirable than ever. He lay with his torso stretched on the mattress and his chest heaving up and down, gazing back at Rin with clear, gentle eyes. The kiss Rin gave him was soft- as if to test how Haru liked it- then he licked his way down Haru's chest, his hands flat on Haru's skin. Rin's lips slid over Haru's hips and knees, even the bottom of Haru's feet- sucking the toes in worship before he crawled up, pressing their bodies together. Pink hair fell over Rin's face as he set his hands on Haru's hips in an attempt to control himself.

'Haru...'

Rin leaned inwards once more before his body suddenly froze, and an ache spread through him-

'What?' Haru asked. Rin shook his head frantically.

'No, I-I... I just remembered it. That day. Haru… sorry. I didn't mean to bring it up…'

'That day' Rin referred to was the day five years ago- the day several months after Haru had woken up as a vampire and he'd told Rin he wanted to kill all of the others. The sewers- once filled- had been completely emptied... that was what happened when Haru felt unhappy: he killed… and he killed without mercy. Every one of the vampires in the pipes had been massacred, until only the two of them were left.

The humans in the slaughterhouses had been killed by Haru, too. When Rin had asked what he was doing, Haru told him that he was setting them free, then he'd dropped a match and all of them had burned- all of them had screamed and the fires had reflected in Haru's eyes as he'd stood watching with his same, calm expression whilst Rin had remained beside him with a lump in his throat. That day had been branded into Rin's memory forever: no matter how many thousands of years he may live, he knew that particular one would never escape his mind.

'You failed,' Haru announced.

'I know…Haru, I'm sorry-'

'I don't need to depend on you,' Haru told Rin. 'Just stay faithful to me.'

Rin, you look good on your knees.

Haru hadn't wanted Gou to live, either: since Rin had demanded Haru should sacrifice someone close to him for their relationship, Haru had felt Rin should also give a person in return. Rin didn't want to kill his sister, but he couldn't say no to Haru; he'd sought out Gou, brought her back to Haru and then killed her in front of him... because, that was what Haru had wanted. Because that was what Haru had asked.

Her dead body was preserved in a freezer room deep within the pipes. She looked beautiful in a white dress with her hair flowing down over her shoulders, her arms crossed over her heart and breasts. Every week, Rin would go down and change the lily in her hair. It was a reminder of his failure to Haru.

Over the past years, they'd met more vampires who'd been given successful antidotes like Rin and had been permitted to leave the pipes of their own accord- always coming back in the end. Upon Haru's instruction, Rin had welcomed them with open arms, waited until they became vulnerable then killed them: there were probably more out there, Rin realised; it was just a matter of waiting for them to come back and exterminating them, one by one. Haru didn't like anything he considered a threat

Naked, Rin crawled back on top of Haru, allowing the other man to wrap his legs around Rin's back and roll them both over- their kisses violent enough to suffocate each other.

'Fuck me,' Haru ordered, parting his legs wide for Rin to draw closer. Even though Rin had dedicated his life toward servitude with Haru, the other man still had a distinctive kink for being dominated… at least that much hadn't changed.

His thumb slid inside of Haru, rubbing repeatedly against his entrance to widen it, using his palm on his other hand to roll Haru's balls, before moving the hand up, wrapping his grip around Haru's member. Haru's gaze focused on Rin's erect dick as he felt more fingers twisting within him- thrusting back hard against them: feeling his needs intensify.

'So eager?' Rin teased.

'That's not the part of you I want... '

'Then what do you want?'

'...'

Rin rubbed Haru's hot flesh, his palms massaging Haru's thighs. Haru's cock had curled up to his chest and Rin leaned in close to lap at the leaking slit, feeding the fire that blazed through Haru's body- he tasted of precum and sweat. Rin's tongue curled around each one of Haru's nipples in turn, until the other vampire was anxious and heaving beneath Rin. Lifting Haru's legs, Rin thrust himself inside- slapping their hips together as they moved. His heartbeat roared in his ears as he felt Haru's hands roam his back, run through his hair, before their lips both met in a fierce, biting kiss and they broke apart, gasping-

'Haru... ka-'

It was more sensual, now: Rin drew out his movements to push himself deeper inside of Haru slowly, rocking himself to get the right angle- kneading Haru's hole until he was immersed to his balls.

Haru, no matter what you tell yourself...

You're just as much mine as I am yours...

Haru's fingertips turned white from squeezing the blankets as Rin sped up, leaning in close to his face, panting on Haru's cheek as their bodies collided in ecstasy.

I love you.

Neither of them said the words, but breathed them into each other's skin- a silent oath shared between them as they thrust: a promise of forever. They orgasmed together- or at least, close enough- afterwards, Rin pulled Haru into his arms, holding him devotedly against his own chest. Rin caught a peek of Haru's fangs and noticed that at some point during the thrusting, Haru had bitten his own lip: Rin leaned in to suck the dried blood away, cleaning Haru then kissing him chastely. Rin watched Haru carefully, his red eyes glowing with love.

'What are you thinking?' Haru asked.

'The usual,' Rin's lips quirked. 'You mean so much to me, Haru.'

Haru's returning stare was imploringly.

'...How much?'

'More than anything,' Rin vowed. 'More than anyone... Haru, you've got all of my eternity. All I can give you, and everything I can yield-'

'Rin-'

'I love you, my Haru: overwhelmingly so.'

Haru pressed his cheek into Rin's chest as Rin held him within the enclosed fortress of his arms. He loved Haru so much- too much. More and more by the day: he always would. The two of them had become obsessed with each other, and that obsession grew with the passing minutes.

Rin didn't know if the 3.3450 antidote that he'd pierced Haru's palm with and now flowed through both of their veins really would make them live forever, or if he and Haru would die together in a few years' time- nor what might come after that. Whether the two of them would be faced with eternal silence or standing before the gates of Hell holding hands, Rin was sure of one thing: that he and Haru would be side by side, bloodstained as they kissed- until the bitter end.
