Astrid finally let me write some story. She has an axe though, so if she changes her mind I am not going to argue.

Marina - I do not speak any other language than English, however I have friends who can translate in a few languages for me (including German), and I also have the internet. I actively encourage people who aren't comfortable reviewing in English to use their native language! Please do not be shy, I will love your review no matter what language it comes in.

-HTTYD-

Eret looked up as he heard the door slam, heard the grunt of irritation and stood just in time to greet a grumbling Astrid, who had kicked off her shoes and was in the process of shedding her light summer jacket.

"What's wrong?"

"Boys!"

"What did I do?"

Astrid rolled her eyes, tossing her jacket aside and padding over to lean into him, relaxing when Eret slid his arms around her.

"Not you, you enormous reindeer shit" Astrid was in a colourful mood, it seemed "one of the stragglers, trying to get me to swap numbers so we could meet up over summer. Even if he wasn't getting pushy just now, I'd have said no. I already fucked him, he was terrible."

Eret snorted.

"Fair enough!"

They were some of the few left on and around campus - the academic year was over, but the twins had a few more days left on their lease before they had to go, and Astrid had packed up in advance so they had little to do but spend the handful of days together.

Then it was back to their parents for a little over two months. That was a long time not to be able to drag Astrid into a kiss whenever the whim took, a long time without hearing the sounds of her in the throes of ecstacy. Sure, the same could be said for Hiccup, but the twins shared a room and had mastered not getting caught years back.

"Where's Hiccup?"

"Supply run. We didn't want any reason to have to leave."

Astrid nodded into his chest, visibly less tense and irate than she was when she'd arrived. Eret rubbed her back, heard her hum happily. It was going to be the longest straight run of time Astrid had spent in their bed - well, beds, but they all liked Hiccup's room best - in months now, since they'd cut down the time she spent with them to avoid suspicion. It was so very hard to care that people might notice sometimes, especially times when Astrid was naked. Or times when she was cute and soft, burrowed in between them under Hiccup's dragon-patterned bedcovers.

Chucking a nonsense movie on TV for background noise, Eret and Astrid lazed on the sofa waiting for Hiccup to return, Astrid settled enough that Eret might have said she was napping if not for the intermittent groping, playful little smile on her lips. They'd agreed to wait for Hiccup to come back, so it was all just mild torture from her really.

"Can you not keep your hands to yourself for one minute?"

"Of course I can. But given where your hand is, I didn't think you wanted me to."

Eret couldn't help but laugh; entirely unintentionally, his hand had come to rest on Astrid's cute butt.

"Well, by all means continue."

Now he was aware, Eret gave his sister a playful squeeze in turn. Astrid squirmed, biting her lip and fuck she was sexy when she did that. And damned if she didn't know it, eyes wide and full of feigned innocence as hands wandered, resting on the straining fabric of his shorts.

"Tease."

"Tease implies I don't intend to follow through. You should know by now that I always do."

As if to prove her point, Astrid nudged him to lie properly on his back, crawling on top of him. Her lithe frame stretched along his, teasing him with holding her mouth just out of reach, hands on his shoulders to hold him down as she leant in so close Eret could feel her breath. He loved that smirk that tipped her mouth up at one side, the spark of mischief replacing that fake innocence in her eyes. Gods, she was gorgeous.

Both turned when the door opened, but by now they recognised solitary Hiccup footsteps. He raised an eyebrow when he walked in, grinned.

"Well, I came back at the right time. Or maybe five minutes early, depending on your point of view. Do carry on."

"Well we agreed to wait for you, so really you got back just in time, else Eret might not have waited."

Hiccup eyed the two of them.

"Yeah, given how you're on top of him I'm guessing you started it."

"What a terrible accusation! See if you get lucky tonight."

Eret snorted. If Astrid held out on Hiccup the entire night, he'd eat asparagus. Just the thought of such a foul vegetable made him shudder.

"Well, even if you managed to somehow resist all this" Hiccup gestured to himself, smug smile on his face "I have a feeling Eret can't."

"I could be persuaded. Probably."

"Traitor. I better put this stuff away. You staying there to defile the sofa again or bed?"

Eret glanced up at Astrid, who seemed to contemplate before nodding toward the bedroom. Eret didn't bother waiting for her to move, picking her up as he stood despite Astrid's protests, laughing as she wriggled until they were nearer Hiccup's bed. Then her focus changed, dragging Eret down with her and humming softly as his weight pressed onto her. If it weren't for how easily he was certain Astrid could have thrown him off, Eret might have worried about her love of being pinned down, but then it was clear that Astrid felt safe enough to explore whatever rough play kinks she had with them.

And honestly, her responses were reward enough. She was incredible.

By the time Hiccup joined them, clothes were quickly moving from bodies to floor, blonde hair flowing through his fingers as Astrid's braid came loose. Hiccup stripped down to his boxers and joined them on the bed, fingers trailing down Eret's back until he turned to his brother, got a blistering kiss for his efforts. He could feel Astrid's eyes on them, got the sense she found it hot watching them the way they did watching each other with her.

If there was something Astrid seemed to like more than being held down by one of them? It was being held down by both of them. Hiccup held her hands down as Eret clamped his hands on her hips, holding Astrid in place tight so she couldn't squirm or wriggle away or grab at him as Eret dragged his tongue over her clit, enjoying the way she twitched and moaned before straining against their hold. She was already wet, but that didn't mean she couldn't get a little more tightly wound under his mouth first.

Of course, they couldn't really stop Astrid if she wanted to move, and she'd broken Hiccup's grip soon enough - Eret wasn't sure their brother tried too hard, since he undoubtedly looked forward to the next part of the fun. Finding himself flat on his back with Astrid on top of him, Eret pulsed with want at the sight; he'd long fantasised about it, and the image of Astrid on top of him had been so much better than he could ever have imagined.

There was something so wild and primal about Astrid when she rode him or Hiccup. Utterly uninhibited, she found the angle at which he filled her best and then fucked Eret like she couldn't wait another second, hair a brilliant golden mess tumbling over her shoulders and framing her face twisted in pleasure. Every sound that fell from her mouth was incredible, from the honeyed seduction to the soft whimpers, feral cries and teasing whispers. Eret held on for the ride as best he could, already pretty certain he'd not hold out long enough for her.

Hiccup came to his rescue, pushing her hair aside to nip and bite at Astrid's neck, his hands sliding over her body until fingers tweaked her nipple, others brushing the base of Eret's cock as Hiccup stroked between muscular thighs. He loved that, loved the fierce power that lay under those sweet smiles and pretty blue eyes. And damned if it didn't give her the fire to keep going strong, nails scraping at Eret's chest as Astrid moaned and cursed, fists curling tight against his skin as he and Hiccup slowly drove her over the edge. She shuddered in his arms, her fingers clutching tight at Hiccup's forearm across her stomach for an anchor as she broke.

Astrid often let out lovely little gasps when she felt them come, biting her lip and humming as though savouring the experience - all three only had unprotected sex with each other, so it was a fairly unique experience, and Eret had a similar appreciation for when Hiccup left him sticky and satisfied...

"Feel better now?"

"Mmm. Lie down time."

Eret chuckled as Hiccup guided Astrid down onto her back, watching her wriggle to get comfortable as she soaked in the happy-chemical dump in her brain. Oh, he had little doubt she'd be ready to go again soon - it really was lucky there were two of them - but he enjoyed her little afterglow moments immensely.

Hiccup gave Eret that smirk that said he was planning something, and that look was proved true soon enough as Hiccup turned himself around, pulled Astrid on top of him to straddle his face. There was something so very inappropriate about how Hiccup was so keen to taste Eret on Astrid and vice versa, but that only served to make it hotter as Astrid moaned aloud, brief tremor rolling through her body before she adjusted to the new touch. He could see how tightly Hiccup gripped at toned thighs, knew how Astrid loved that too, that she was happy to leave them bruised and sore and sated.

"Well, don't just sit there, else I'm gonna win this round."

Astrid needed no further explanation or encouragement, stretching her upper body over Hiccup's middle until she could take his cock in her mouth. The whole 'stamina' game had become a regular occurrence, largely for fun and their stakes were usually minor, daft things like who picked dinner or the movie. But they were all kinda competitive, Astrid especially, and so they went all out regardless of the 'prize'.

Judging by how Hiccup had to stop his own ministrations for a minute as Astrid clearly gave it her all, Eret knew today was no different. The sight of them alone aroused Eret, even without muffled moans and hands groping, lewd wet noises of mouths and tongues. His cock swelled, and given how cocky Astrid was about 'winning' their little games so much, Eret thought a little payback might be in order.

"Think you can handle me too?"

Astrid moaned eagerly around Hiccup's cock, eyes turning to where Eret knelt at their side, somehow managing to fucking smirk at him in the process. Raising her head to catch her breath, Astrid's throaty murmur of "bring it on" was all the encouragement Eret needed to move behind them, feeling a giggle bubble in his chest when an eager tongue swiped at his cock from where Hiccup laid under Astrid still.

"Oh fuck, we need to do this position more often."

Her voice was rough with arousal, muscles quivering around Eret's cock as she took him in again, still slick from before but Eret wasn't complaining in the slightest. Bracing a hand on Astrid's shoulder as he began thrusting, Eret was quietly confident Astrid would soon be falling prey to the dual stimulation. Hiccup made sure to let Eret feel his tongue again, the wet muscle skittering over his cock between thrusts, retreating again to undoubtedly torment Astrid in ways she'd adamantly said she could handle. Once Eret found that angle that made her shake and shout, he kept at it, loving the way Astrid devolved so easily.

One arm rested on its elbow, a balance to match her knees on the mattress. Astrid's other hand scrabbled at the sheets, pulling the fabric tight as her back arched, cries muffled around Hiccup but a potent sound all the same. He could hear Hiccup whimper, knew that Astrid was still more than capable of driving him to distraction, all three quickly and easily lost in each other. She didn't fail to try and push Eret either, squeezing at his cock until he grunted and if he could see her face, Eret knew she'd be smirking.

Astrid couldn't hold out, Hiccup falling from her mouth as she spasmed around Eret, making those desperate sounds when climax rocked her, fist slamming against the bed as she swore and keened.

She was right; they would have to do this more often, now the twins had seen what it did to her. If not for them both holding her up, Eret was certain she'd simply melt in place on top of Hiccup. A mischievious lick had Astrid whimpering, a little too sensitive to tolerate it. Eret pulled out, helped Hiccup roll her onto her back next to them, flushed face covered in her hair where it stuck to sweaty skin. If there was a better sight, Eret hadn't found it yet. Maybe well-fucked Hiccup as an equal contender.

"You both suck. That was unfair advantage."

Eret laughed.

"You were the one who said, and I quote, 'bring it on'."

Astrid grumbled.

"Shut up."

Hiccup rolled onto his front, raising up so he could lick Eret's messy cock, all wide green eyes and warm willing mouth as one hand came around to squeeze his ass. His cheeks hollowed as he sucked, sudden sharp moan vibrating along his shaft. Eret's eyes followed the line of Hiccup's body, saw Astrid had obviously recovered enough to finish what she started, blonde head bobbing over Hiccup's lap.

"First to come has to ride in the back on the drive home."

"Doesn't that technically mean Astrid-"

"Front seat!"

Astrid claimed, grinning up at Eret before she turned back to Hiccup. There was no point arguing with her, really. Hiccup was soon distracting him with his tongue, drawing him closer to the edge with every move of his lips back and forth over the ridge of his glans, heady mix of wet suction and nimble tongue soon more than Eret could take, fingers in Hiccup's hair flexing as he came with a low groan. There was no hesitation before Hiccup swallowed him down, pulling back with a look of triumph that he'd won their little contest, though the look soon faded as Astrid's constant oral attentions dragged him over the edge too.

Slumped on the bed to catch their breath, Astrid had had longest to recover and was up first, calling dibs on the bathroom.

"Why do girls always call dibs?"

Hiccup quizzed, and Eret looked to Astrid too - it was a fairly common thing they experienced, and had never thought to ask why.

"Aside from the fact that women are supposed to pee after sex, if you don't use a condom then there's a mess to deal with."

Question answered, they waved her off.

"As you were."

Once done, Astrid meandered off to the kitchen to presumably raid it for snacks, leaving the boys to clean up in turn and head back out to join her. Refuel trips were good. Eret grabbed a bag of jerky - Hiccup got his favourite! - and sat down to wait for the other two. Astrid slumped on the sofa, wearing stolen shorts and a lazy smile that faded somewhat as she glanced at her phone.

"Everything alright?"

"Hm? Oh, yeah. Just Heather. I missed a call from her to let me know she was settled back in home, and because I missed it she sent me a text letting me know she still wants details."

"About?"

Astrid rolled her eyes.

"My secret boyfriend and if I'll be hooking up with him over the summer."

Hiccup perched next to Astrid, hand stroking idly along her leg.

"Excuse me?"

"Heather is convinced, and she's not entirely wrong, that I'm seeing somebody. And was bugging me about telling her who before we left. I got rid of her, but texting lets her bug me about it from afar. Then no doubt she'll quiz me about it when we come back."

She groaned, dropped her phone to the table and rubbed her face. Eret nudged her, happy when Astrid leaned into him. Sometimes things like Heather worried him, reminded Eret that bringing Astrid into their... whatever it was, had wider reach than just he and Hiccup. Nobody questioned twin brothers spending time together, or living together. But nobody knew Astrid was their sister, because their dicks had gone and made it impossible to let that particular fact out without a lot more consequences. Like disownment and prison.

But none of that seemed like a reason to worry when they were together.

Being back home was... weird. Maybe because it no longer felt like home to Astrid. There was a sense of childhood and family there, and gods she had missed her parents, but there was a disconnect too - she'd felt more at home back in Hiccup and Eret's little flat, where they could just be them and not worry much. Beyond those walls, the world came rushing in to remind them they all had a secret, one that they couldn't share.

And while Astrid found the whole lying and hiding such details from their parents much easier than she'd expected, her mother still knew her too well to be entirely fooled, and Astrid struggled a lot more whenever Valka's eyes took on that sad, worried look, fearing for her little girls happiness.

"You would tell me, wouldn't you? If something was wrong?"

"Of course I would mom. I'm fine, honestly."

That was when Astrid tasted guilt, bitter on her tongue; it might have been easier than she expected, but that didn't mean she liked lying to her mother. It was just necessary now, hiding the secret, always wary of saying too much.

Eret and Hiccup... at first, Astrid thought they were overconfident idiots. Then she realised they weren't actually acting any differently to every year previous. They'd always been tactile, playful, grabbing each other and wrestling. It wasn't much different to being back in their flat, only they always had clothes on and they didn't kiss. And because they were twins, and had grown as basically two parts of one unit to most, nobody questioned - not even their parents.

Astrid only really noticed because she saw things through a new lens, knowing what went on in their room after dark, that the TV always on in their room hid the sounds of Hiccup panting as Eret fucked him, or Eret's colourful multi-lingual cursing.

Honestly, she was a little jealous. Not that they were together. Just that she wasn't in there with them. The last weeks at university, with them agreeing to cut down Astrid's time spent in their rooms, their beds... that might have been better preperation for the next-to-zero opportunities Astrid had to be alone with either, let alone both of them now. But then they'd spent several consecutive days together, barely bothering with clothes or even leaving the bed for more than bathroom breaks and snack runs.

After a week or so, Astrid began to relax a little. That nagging sense of they know, they know had begun to fade, and so Astrid dared to breathe in relief and not panic about every word, every look that could be miscontrued.

"Relax."

Eret breathed the word against her ear, catching Astrid on her way back from the bathroom and dragging her into a tight hug she definitely needed.

"I am relaxed."

"No you're not. But you will be."

He made an excellent point, between tugging Astrid into the boys room for stolen kisses as he pressed her up against the wall, leaving Astrid weak in the knees and ridiculously turned on. Their parents weren't exactly looking for signs of illicit sexual attraction between their children. So unless they were too obvious to ignore, most things would slip under their parents radar.

She didn't let them tempt her into their bedroom again - Astrid knew she'd never leave if they did - but she did relax. And her brothers noticed, relishing the change and taking advantage of it. Eret held her arms as Hiccup tickled her, dodging her kicks and refusing to stop as she squealed and did her best to wriggle free, quite prepared to kill them both when their parents walked in and laughed at the ridiculousness before them.

"I see living away from home brought you three closer."

Oh, you have no idea mom.

"Well, Astrid is always over to steal our food and get out of paying for the laundromat."

"If I don't come over to get it, you bring it to me."

There was a smirk on Hiccup's mouth that made Astrid's belly quiver; her words could apply to both food and sex, really, and Hiccup knew it.

"Plus we gotta keep an eye out during parties and stuff, make sure nobody takes advantage."

If their parents weren't right there, Astrid might have joked that more often than not, it was them she'd gone home with. Not that they had taken advantage of anything, unless Astrid's high sex drive counted.

"I am quite capable of kicking some drunk guys ass, thank you very much."

Eret let go of her arms, wrapped his around her and squeezed her tight.

"Still. We take care of her, don't worry."

While the conversation faded there, it had clearly stuck with Valka, as she approached Astrid that evening while the twins and their father were talking dinner - the women were firmly banished from such tasks for health and safety, apparently.

"So, speaking of boys earlier... is there anyone?"

Astrid shook her head, tried not to answer too quickly or forcefully lest her mother suspect she was hiding something.

"No, not really. I mean, I hooked up with a few guys here and there, but nobody I could even call friend with benefits. I was pretty busy with uni work anyway."

She'd always been able to talk sex with Valka if necessary, though now Astrid was having the undisputed best sex of her life and couldn't say a word it felt ironic. But mentioning that she had a few one night stands didn't phase her mother at all, since she knew Astrid was responsible and understood condoms and birth control.

The slip up she'd had niggled, but Astrid shoved it away.

"Well, I suppose you aren't necessarily there to meet the love of your life. I was probably quite lucky there."

"Yeah."

Valka patted her hair softly, left Astrid with a lot of thoughts she'd rather not have. No, she wasn't at university to meet a future husband. But she hadn't gone there with the intent of bedding her brothers either. And it left her wondering what would happen after. Because while Hiccup and Eret had a vague thing of "if we meet someone else, we'll stop", Astrid couldn't help wondering when they would manage that, given that the majority of their sexual encounters were with each other, Astrid or as a pair with someone only out for a one night stand.

Astrid was reminded that one day, it would stop. It had to.

But not yet, Astrid told herself. Someday, yes, but not now.

-HTTYD-

Someone get Astrid a hot chocolate damnit.
