HAPPY BIRTHDAY, HEATHENVAMPIRES! :D

Undine - 10

That night, neither Hiccup nor Eret got much sleep. After the first shock of realisation had calmed, they'd compared what they'd seen, methodically but still slightly detached. It was just too surreal. The Undine, a literal mythical creature, was real. Even Hiccup, who hadn't dismissed the stories as legends quite as easily as Eret had, was stunned. There was a difference in believing something might be real and knowing that it was real, after all.

At some point, Eret opened his research file about the Undine on his laptop while Hiccup went to prepare them big mugs of tea and coffee respectively. He was sure that they would need it.

Hiccup had seen all these documents before, but he had to admit that they felt differently now, even though they still didn't tell them much.

"It makes no sense," Eret exclaimed after a while, frustrated. "Nothing of all this. So maybe the initial story was true and the beautiful woman that had been seen wandering through the night really was her."

Hiccup nodded, slowly and with his lips twitching. The woman – or Undine, or mermaid, or spirit, or whatever else they both had seen – definitely was beautiful, there was no denying that.

"That much might be true after all," Eret went on without a pause. "But the rest? Maybe people are right and she really is something of a bad-luck-charm. But I don't think so, there's nothing connecting her with those petty events and I wouldn't say that we were cursed by bad luck since our arrival here, either."

Again, Hiccup nodded. "I agree. These stories are nothing but fairy tales, people trying to explain away their own faults and mistakes or bad turns of fate. How could she even be responsible for those?"

Eret grunted and gave him a weird look. "Aye. Although, given that she exists, we can't rule out anything just yet. Who knows, she might have some talent that influences people and cause such events if that's what she desires. Hel, she might even be able to wield actual magic!"

He threw up his hands in frustration, making HIccup cough to hide his grin. Eret didn't believe in magic whatsoever. For him to kind of considering its existence now was a huge thing. "Yes, but we know she doesn't. She's not evil," he threw in to distract Eret.

But apparently, that hadn't been quite what he'd wanted to hear. Yes, he became calmer, but not in a good way. "Are you sure about that?" he asked in a low voice. "It's not as if we know anything about her. Yes, she didn't hurt us. Yet. But what about the other story, the one Mrs Ingerman told us? The one about the dead boy?"

"But that's just another story, nothing to be taken seriously," Hiccup argued, frowning. How could Eret not see that? "She must have been here for ages, definitely since we moved here. And even though we live so close to the ocean and regularly went swimming, she never attacked us, never harmed us, never even willingly showed herself to us. And when we spotted her, she fled, as if she was afraid of us. How does that make sense when she's really as dangerous as Mrs Ingerman thinks?"

Eret looked troubled, and Hiccup felt sorry for having caused that in his boyfriend. He didn't want to argue about this. But it was all just so weird, so confusing, and Eret's mood just made no sense to him.

Slowly, Eret shook his head, a deep frown on his face. "I don't know, Hiccup. But the fact remains, we don't know anything about her motives, her powers, Hel, we know nothing. All we can do is make assumptions, just like the people living here forever. And they all think she's dangerous. How can you trust her so easily?"

To that, Hiccup had nothing sensible to say. "I don't know," he mumbled. "I just do." He understood that those words wouldn't be able to convince Eret though. So he made another suggestion. "Look, how about this. We leave it for now and try to get some sleep. We're both too tired and agitated to think clearly anyway. And then we see how things look in the morning. Maybe we can make some tests, go swimming again and try to find her. We always stay together so nothing can happen," he added quickly when he saw how Eret wanted to object. "But before we can make a decision, we need to find out more. Do some researches."

Hiccup knew that Eret still wasn't entirely happy with this idea, but he obviously wasn't against letting the topic drop for now. "Okay. Let's see how things are in the morning."

. o O o .

When Eret woke up in the morning, it was to the incredibly pleasant sensation of something hot licking and kissing away at his already half-hard cock. His needy groan in response must have been enough to tell Hiccup that he was awake, because just a moment later his ministrations gained a lot more purpose, a nimble tongue swirling around his glans before eager lips took him in and the sudden suction made him nearly arch off the bed.

Eret greatly enjoyed waking up like this, squirming beneath Hiccup's skilled mouth as he took him down his throat, the tight muscles clenching when he swallowed around him nearly his undoing. He moaned and trembled at the exquisite sensations, ready to burst in an almost ridiculous short time. Hiccup was just too good at this. It only took a few minutes, then he came with a guttural groan, Hiccup swallowing him down nearly too much for his sensitive nerves. He lay still, panting, when Hiccup pulled back, a teasing spark in his eyes, and crawled back up Eret's body, placing playful bite-kisses on his nipples before claiming his mouth in a deep kiss.

Neither of them ever minded tasting themselves on each others' tongues, so Eret responded without hesitation, pulled his boyfriend into his broader arms and held him close, one hand roaming down to find Hiccup half hard already. After years into their relationship, they knew each other so well, giving Eret a fairly good idea of what Hiccup was up to. With one hand, he felt for the lube they kept near the bed, the other roaming down Hiccup's back and over his firm ass, testingly brushing a finger over his hole. As expected, Hiccup let out a wanton moan and bucked against him, his eyes full of desire as they met his. Grinning, Eret rolled them around until Hiccup lay beneath him, then resumed kissing him as he slowly pushed generously lubed fingers inside him.

Hiccup wasn't always in the mood for prostate stimulation, but when he was he went all out. The first brush against those sensitive nerves made him moan and shudder, the next whimper and arch. Eret greatly enjoyed the show as he worked him open, Hiccup's hands clenching at the sheets in no time, his knuckles standing out white. His cock was throbbing, bobbing to beg for attention and leaking one pearly white bead of precome after the other. He had his teeth gritted to keep himself from begging for release or right out screaming, and the cords in his neck were so tight that Eret couldn't resist sucking a harsh bruise over them.

"Fuck, that's – Aah – that's enough, Ret," Hiccup gasped in a short moment of control, weakly pushing at his arm and wriggling around until he had one leg on each side of Eret's hips.

Eret nearly laughed at his eagerness and the impossible combination of innocent wide eyes and a seductive smirk on Hiccup's face. Gods, how he loved this idiot! Slowly to tease his boyfriend a little more, he reached for more lube and spread it over his cock. Fingering Hiccup had been enough to make him hard again as well, and he only needed a few more strokes to ensure he was ready.

"C' mon!" Hiccup pleaded impatiently, squirming and bucking to make his point. Eret might have drawn it out a little longer, but he was just as eager, pushing Hiccup's legs up a little and positioning his cock at his ass, hissing at the contact.

"You ready?" he panted, blinking to get himself to focus again. Amidst their eagerness, it would be all too easy to hurt Hiccup, which was something he wanted to avoid at any costs. No amount of pleasure was worth that form of discomfort. But Hiccup just gave an impatient whine and nodded, twitching to make him move.

Pushing in slowly so as to not overwhelm either of them drew stretched moans from them both. Eret shuddered at the heat wrapping around his cock, at the rippling muscles that seemed to suck him in even deeper. Involuntarily, his hips bucked forward, sinking deeper into that hot little ass and apparently hitting Hiccup's prostate right on as he gave a chocked cry.

"M-more," he moaned. "Fuck, Ret, more. Please!"

Eret's mouth stretched into a grin. As calm and composed, timid even, as Hiccup usually came across, he really was surprisingly wild when it came to sex. It's always the quiet ones… he mused, then settled more firmly, kneeling between Hiccup's legs and holding him by the hips, and began to move for real.

He started with measured, slow strokes only, but very soon picked up speed and strength, lengthening his thrusts until he fucked his needy boyfriend with abandon. Fuck, that was good! Precome and lube made the slide easy, clenching muscles sucking at his throbbing length until he could think of barely anything but the pleasure surging through him, pooling low in his belly.

But not yet. Eret fought to hold back, to last as long as he could. Hiccup's cock stood proudly between them, throbbing and leaking, begging to get touched. But neither of them did; it was how Hiccup preferred it. It always took a little longer for him to come just from this, certainly longer than Eret who took Hiccup's cock more regularly, but the foreplay had been a good start and the show was always worth it.

Hiccup twisted and arched, cried and sobbed in his growing need for release. Eret was jabbing at his prostate without a moment's break now, thrusting into his boyfriends' lithe frame with all his strength, knowing that he could take it. Eret's grip became tighter when he felt his own climax closing in again, but he fought to hold out as long as he could, knowing that Hiccup was close. Just a little more, just a few more thrusts, just–

"Oh, FUUUCK!"

Hiccup howled, body convulsing as pleasure surged through him, making a mess of his stomach and the bed around them. His hands were tearing at the sheets, his muscles tensing, clutching him tightly, and Eret couldn't hold back any longer either. With a low grunt, he succumbed to the sensation and the amazing sight in front of him, his hips shuddering, pressing in close.

After a quick clean-up, Eret dropped next to a pretty much boneless Hiccup, his typical lopsided grin even wider than usual. "Damn, that was fantastic," he hummed as he draped a lazy arm over freckled skin. "Good morning, by the way."

Hiccup chuckled weakly. "Yeah, was pretty good, I'd say." Then he turned a little to better snuggle into Eret's embrace. "I love you. You know that, right?"

Smiling, Eret leaned in and brushed his lips over Hiccup's temple. "Yeah. Love you too."

They stayed like that for nearly an hour, lazily cuddling, exchanging kisses, and simply enjoying their closeness. But eventually, they'd both recovered enough to get up, the need for breakfast and the bathroom growing too strong. It really was a perfect morning – until they changed the soiled sheets of their bed.

"So, what are we going to do today? Have you thought about my suggestion from last night?" Hiccup asked, pretty much out of the blue.

At first, Eret wasn't sure what he meant, but when he looked up to find Hiccup suspiciously innocently focussing on redecorating the cushions, it dawned on him. He'd nearly forgotten the incident of the previous day, but now it all came back to him. The face of the Undine as she floated right below him through the water. And then seeing that same face again on Hiccup's painting, gazing at him with that same mysterious expression. And the question what do now, now that they knew.

"You mean looking for her? Trying to find out more about her?"

Hiccup nodded and looked at him expectantly.

With a sigh, Eret let his hands run through his hair. He wasn't sure what to think, what to expect. He'd heard Hiccup's reasoning about how she hadn't done them any harm even though she certainly had the opportunity in the past. And it wasn't that he actually believed her to pose a threat to them. But there was still the story about the dead boy, and somehow he felt that there was more to that story than just another fairytale where people blamed a common tragedy on a local myth.

And just casually thinking about something like an Undine as something real gave him a headache. Yes, they had proof, sort of. But his mind still refused to believe it.

"Okay, let's see if we can find her," he eventually gave in, smiling at Hiccup's eagerness but not expecting something to come of it. Unless she showed herself to them again, longer and more clearly, maybe even interacted with them, they wouldn't get any solid information. And given how quickly she'd disappeared both times one of them had spotted her… well, Eret highly doubted they would even get so much as a glimpse at her.

And as it turned out, he'd been right. They spend nearly half the day in and around the ocean, swimming out to the rock formation and diving below the surface. But no matter how hard or for how long they looked, they couldn't find anything. The ocean was just the ocean, rocks only rocks, and fish only fish.

Eret could sense that Hiccup was disappointed by their lack of results, but he still marked the day as a success. Even with them now knowing about her existence, she hadn't harmed them in any way. There was no need for secrecy anymore, except that she probably was indifferent if not actually afraid of them. Eret let that assumption slide, not in the mood to argue again. The day had been a good one, all things considered, and it felt good to simply sink into their fresh sheets, exhausted by the long day out and more than happy to have each other for extended cuddling.

One thing was for sure though: No matter how much he wanted to simply drop the entire topic, Eret knew that he wouldn't be able to do that. For quite some years now, he'd researched myths and legends, never even considering they might be true. Now, he couldn't help but feel differently, and he knew that he wouldn't be able to rest until he'd found out more.

. o O o .

Far out in the ocean, the creature was hiding, deep down below the surface where she was sure that no human could ever find her.

And she was scared.

What would happen now that they had seen her? What would that mean? She knew that she wasn't supposed to interact with humans, ever, but she didn't know why or what the consequences would be.

For the rest of the day and all night, she stayed there, brooding and wondering and pondering what to do now. Was there even something she could do? She already knew that she physically couldn't stay away, but she also couldn't get that close again, couldn't risk them seeing her again, or… or something would happen. It was so confusing, so frustrating; being ruled by this vague knowledge without knowing why.

In the morning, she already felt the need to swim back again, could hardly resist the lure. But when she felt them in the water later that next day, even over this distance, staying away became impossible.

Just a little bit closer, she told herself. Just enough so I can watch them from afar.

The moment her eyes found them, she felt as if a strong current that had been pulling at her without her noticing had suddenly set her free; She felt so light, so relieved. Her cool lips twitched into a smile as she watched them swimming around and diving to the ocean's ground. She wanted to get closer again, to swim around them, playing, pretending. But she didn't dare to do it. This is close enough, she decided, settling amidst a field of seagrass, just close enough to make out their forms amidst the waves in the distance, and quietly hummed to herself.

It felt like hours before they left the water for good, hours that seemed to fly by in the blink of an eye. And they weren't enough. When the night came, she settled back on her rock near the coast, watching the little construction with its warm light, and felt the full impact of her situation.

She was trapped. She couldn't go back and leave but she also couldn't go further, closer. All she could do was keep this safe distance, watching but never getting closer, until they wouldn't be here anymore. The thought made despair rise inside her, made her keen helplessly. That wouldn't be enough, couldn't be enough, she couldn't resist the longing for that long, already felt how it grew stronger and stronger. She wanted to get closer, to see, to learn, to feel.

But it was too dangerous.

She had no choice.

She was trapped…

. o O o .

Okay, so this chapter didn't turn out as planned. There were so many things supposed to happen and even my rough keywords already were longer than 1500 words. But then, everything came differently.

The boys, mostly Hiccup, became incredibly horny and insisted on the smut. That wasn't even planned. But you know how characters are; they can never behave! So this happened, and I call this chapter quits here. More to happen in the next then...

Hope it was still bearable.
