-HTTYD-

Hiccup stretched, rolled up to sit on the edge of his bed. The other side was empty, cold. Not terribly unusual. He fixed on his prosthetic leg, stood and headed to the connected bathroom. There was a stray pair of high heels he didn't think belonged to either resident of their flat. After he peed, cleaned up and brushed his teeth, he ambled out toward the kitchen in search of morning caffeine. Stepping over a discarded t-shirt and some shorts of questionable comfort only furthered his suspicions.

As he expected, there were two bodies on the pulled out sofa bed. One was his boyfriend. The other was an absolute stranger, though Hiccup supposed she was cute enough. Not his type, from what he could see of a head of dark brown hair cast all over the place. Hiccup clicked the kettle on, turned to see amber eyes peeking over at him.

"Morning. Coffee?"

Eret nodded groggily, trying to extricate himself from his bedmate without waking her. Mostly successful, he smiled sleepily at Hiccup and ensured the blankets were covering the woman's dignity. Hiccup prepared his boyfriends coffee, slowly held it out without spilling any on their houseguest.

Sipping at his own hot brew, Hiccup perused the kitchen and wondered if she would be a hasty walk-of-shamer, a "whoa he's got a fake leg!"-er or a chilled out one who stayed for breakfast. He added a third mug to the side just in case, as most people wanted caffeine in the morning and from personal experience, Eret could certainly exhaust someone.

They'd encountered all sorts of people in their three year relationship - open basically from the start, both in agreement they could have one night stands. Hiccup didn't care what his boyfriend did, so long as condoms were used and Eret never lied about where he was. Eret had taken a little longer to adjust to the dynamic, but they had talked about it openly and now the two had settled quite well with it.

Most of their one-nighters didn't really like that. Eret was better at picking those types somehow, and had been slapped by them more often than Hiccup had. Which Hiccup found funnier than he should.

They only had one rule - never both go after the same person. That way there was no fear of jealousy over a preference, since Hiccup was slender, quieter and more artistic while Eret was muscular, had an air of bravado to his charismatic nature. Nobody ever preferred them equally, and so they agreed on that rule early on. Since then, it had been pretty muc smooth sailing.

Except when Eret's dad found out. Already a little uneasy about his son having a boyfriend, the news Eret continued to have sex with both women and other men was very confusing. He wasn't sure why Eret didn't just get a girlfriend and 'deal with his unusual wants' in private. Eret's mother and Hiccup's parents were on board enough; so long as the two men were happy, they were.

Eret's friend of the night before began to stir as Hiccup finished his coffee, peering around from under the blankets and shrieking slightly in surprise to find Hiccup stood there, clad only in boxers and looking totally at ease.

"Who are you?"

"I'm Hiccup. I live here. And you are?"

"H-Hazel. Oh, hi Eret."

He didn't think the girl was hungover or even still steamed from the previous night, just groggy and disoriented by strange surroundings and a new, unexpected person.

"Morning."

"Would you like a coffee Hazel?"

She nodded, tugging the blanket tighter to herself and Hiccup made a show of turning away so she could scramble around locating her clothes.

"I didnt see anything, if you're worried. Eret made sure you were covered up."

He called back, hoping she wouldn't think he was a pervert. He didn't think assuring her she wasn't his type was the way to go.

"Did he say his name was Hiccup? What kind of name is that?"

Well, Hazel didn't do subtle whispers, that was clear as he overheard them.

"His names Henry but that's just what everyone calls him."

"Has he got... you know-"

"A prosthetic? Yeah. Why?"

"Just curious."

Hiccup went back out holding fresh coffee for the two late night lovers. Eret thanked him and shuffled back to sit more like it was a sofa, stretching out his tattooed legs while Hazel tied her hair up in a loose ponytail before accepting hers.

"Thanks. Aren't you gonna get dressed?"

Her eyes drifted down as she spoke. Hiccup could pretend it was her checking him out, but they both knew it was about the leg.

"No? It's my house, the only place I am not obligated to wear anything. Except my leg, I can't really walk without that."

Hiccup didn't mind people asking, it was natural for curiousity. He minded when they looked at him like he was a freak.

"Isn't it weird for two guys to hang out like, nearly naked?"

She downed her coffee too fast, wincing as it burnt her tongue but Hiccup knew she was anxiously trying to leave faster without seeming rude. Eret gave Hiccup 'the nod' from behind her, so Hiccup answered quite calmly.

"Probably not, but especially not when he's my boyfriend."

Hazel dropped her mug. The remnants of hot coffee splashed on the floor, and mostly on Hiccup's artificial limb rather than burn the organic one. She whipped around to Eret, scandalised.

"You didn't say you were gay!"

Shrugging as he placed his half-full mug aside, Eret shook his head.

"I'm not? I woulda thought you noticed that last night."

"Then you're a cheat!"

"Nope. Notice that Hiccup isn't the slightest bit concerned?"

Shaking her head, Hazel looked around hastily. Noting her bare feet, Hiccup pointed.

"Your shoes are in the bathroom."

She scuttled toward it, muttering under her breath and escaping pretty sharpish with her heels in her hands. Hiccup picked up her 'discarded' cup, thankful they hadn't gotten around to carpeting the living room yet as he wiped up the mess. Eret shook his head, bemused.

"Think we should start telling people we're in an open relationship before we bring them home?"

"I do, sometimes. Tends to bother guys more than girls, I think its an ego thing. Well, her loss. Breakfast?"

"Yeah. I'll get this" he indicated the bedsheets and blankets Hazel had shared with Eret "in the wash. Man her perfume was strong."

"I thought it was just me thinking that."

"Nope. Extra bacon?"

Eret gave his best pleading look, knowing Hiccup would acquiesce.

"You got it love."

Soon enough their little flat was back in order, washing machine spinning away merrily and the smell of bacon and coffee in the air as they enjoyed breakfast together.

"So, did you do anything exciting with your night?"

"Finished a job, played on the Xbox. Called my mom, then crashed pretty early I guess. When did you get in?"

"Bout half past midnight. I only know because she told me though, girl checked her phone while I was getting my shirt off."

Hiccup laughed, biting into his rapidly-cooling eggs.

"Was it worth the morning dramatics?"

"Eh. I've had worse. I've also had better. Would have been chalked up a good night overall if she hadn't freaked this morning."

Eret cut his bacon rashers in half, cramming them and fluffy scrambled eggs into buttered bread. He ate so much, it was honestly baffling to Hiccup that Eret wasn't the same size as his father Stoick 'the vast' Haddock.

"How was your mom, by the way?"

"She's good. Dad's driving her up the wall though, apparently he's been woodworking obsessively lately and she's sick of the house resembling a hamster cage with all the sawdust."

"What's got him obsessed with working wood?"

Eret sniggered as he asked, totally as much the twenty five year old adult as he looked. Not.

"I regretted asking when mom said he's probably holding out for grandkids."

His boyfriends eyes widened.

"You did mention to him that I'm sorta lacking in the ovary department?"

"Yes! This is the problem with being an only child. I think it's one of the reasons dad is alright with our open thing. He's hoping we'll get a girlfriend."

"Then he misunderstands our relationship entirely."

"Yeah, I tried to explain that to mom but then apparently dad was outside with an axe and half a tree so she had to go."

Eret snorted into his coffee.

"From anybody else, that would be a really worrying night time phone call."

"Yeah. I agreed we would visit them, go over for dinner some time soon, maybe stay the night depending on driving conditions. Otherwise they'll come here and dad will complain there aren't enough lethal weapons on the wall."

Eret started laughing so hard he had to put down his cup, clutching his stomach.

"Again. That would be worrying from anyone else."

"Yeah... do we have something to do today? I was sure we did."

"Well, I do. You can come."

Hiccup eyed his boyfriend.

"What is it?"

"Tattoo! I'm getting my pirate piece finished."

"Oh yeah. You better shower first."

"I know! Calm down Hic. It's not you getting stabbed with needles today."

"Or ever."

"C'mon! You know you want a dragon tattoo."

Hiccup shook his head. He'd had quite enough of needles in his many hospital appointments for his leg, lost in an accident as a teenager. Eret had never been the slightest bit fazed by his boyfriends metal limb, but he was endlessly trying to get Hiccup in the tattoo chair. He just wanted to share his passion for tattoos with his lover.

"You comin' hot stuff?"

"I'll be in in a few, you can wash that perfume off yourself first."

Hiccup loaded the dirty plates and cutlery into the sink to wash later, wiped the sides down and picked his outfit for the day before he joined his boyfriend in the cubicled shower, having changed to his 'showering leg'. Cleansed of artificial floral scent, Eret wrapped wet arms around Hiccup's middle and kissed the side of his jaw once he was in reach, pulled him beneath the water spray.

"Morning."

Hiccup nudged him back a little to get water running down over his back before a chill could set in, but Eret wouldn't be deterred long and grabbed him close again.

"You know we've said good morning to each other already? Even had breakfast!"

Eret chuckled, hands sliding down Hiccup's front as he pressed forward, erection pressing into Hiccup's lower back.

"Yeah, but it's not a good morning yet."

Rolling his eyes fondly, Hiccup arched his back as Eret found him half-hard, stroking him to full firmness and biting teasingly at the side of his neck. The support railing fitted to their shower wall was, outwardly, for Hiccup as he was prone to balance issues where there was a lot of moisture. However, it had been 'misused' for shower sex a considerable amount of times.

Eret grinned when he knew he was successful, retrieving condom and lube from the waterproof bag kept in the bathroom for just such an occasion. Gripping the support railing for dear life, Hiccup felt slick fingers probe his ass. They switched often, but Eret had a thing in the shower and Hiccup had no complaints. Two fingers slid in pretty easy, Hiccup regularly used to accepting and welcoming such an intrusion.

"You're always easier in the morning."

"Relaxed after sleep I g-uess-ssss."

Hiccup's words caught on a gasp as Eret found his prostate, stroking the sensitive bump and forcing him to grip tighter. Eret knew his balance was precarious, used one hand to hold Hiccup's hips for additional stability. He wouldn't go far himself, stopped by the tiled walls on three out of four sides. Fingers stretched and lubricated him, nudged at the nerves that sent lightning through his body.

"Fuck, c'mon 'ret!"

When Eret's name got shortened, he knew Hiccup was growing impatient and chuckled, adding a little more lube to the party to make sure his boyfriend was wet enough.

"You ready Hic?"

Nobody got to call him 'Hic' except Eret. Just like nobody else could call him Ret. That was theirs.

"Mhmm."

Hiccup rocked back as best he could, pushed Eret's fingers deeper inside himself and moaned at the wonderful feelings inspired. Eret slid the digits out, left him cruelly empty and wanting. His erection twitched as he heard the tear of foil, along with some grumbling about doing it with wet hands. The initial pressure always surprised him a bit, but he was quick to adjust and Eret slowly filled him until broad chest pressed to narrow back.

Eret's arm wrapped around his waist, helping hold Hiccup upright while the other hand gripped his hip for Eret's own leverage. Hiccup felt cradled, coddled and he adored it.

"Gods I love your ass H."

Hiccup wasn't brainless enough not to sass his boyfriend just yet, tightening muscles around Eret's cock and enjoying his sharp intake of breath.

"Funny that."

A swift smack on his ass made him jump, clutch the railing for support as Eret chuckled and reached to squeeze Hiccup's cock.

"You know what your sass gets you."

"You know you're meant to be fucking me?"

Almost as if on cue, Eret pulled back and pushed forward, the motion surprising a moan from Hiccup's throat. Bracing himself, Hiccup let the rolling thrusts of his boyfriend fill him repeatedly, thick cock dragging across his prostate again and again with delightfully pleasurable feelings the result. His knees went weak but Eret held him up, hands gripping the bar tighter when a broad hand came to play with his cock.

It was all too much too fast and Hiccup revelled in it, body coiling tight with each push toward climax. Eret stroked him in time with each thrust, wet skin of his hips against the wet skin of Hiccup's backside a guttural, sticky sound that he loved far too much. Morning sex usually didn't last that long, and that day was no different as Hiccup spilled over Eret's hand, splattering up along the tiles and down into the water running to the drain below with a low, satisfied groan.

Hot, wet and sticky coated Hiccup's lower back as Eret pulled out, removing the condom and taking advantage of the place Hiccup minded mess the least as he came. They panted and rode the wave of reward-hormones flooding their bodies, Eret turning him around to let hot water rinse his back and ease the pleasant ache of being well-fucked.

"Mmm. Now it's a good morning."

"Told ya."

Clean, dry and dressed - after a brief fight for who got the hairdryer first - the two had a light snack before heading out so Eret could be mildly tortured for the sake of body art. Hiccup sat and watched, chatting with his boyfriend as Eret laid on his side, having the design that wrapped around his lower back and the right side of his ribcage coloured in and any faded lines touched up.

"Y'alright there lad? I know this is a sensitive area."

It definitely didn't tickle - Hiccup watched Eret occasionally wince and his fist clench as certain spots were touched upon - but Eret replied to the tattoo artist calmly.

"Worth it! Can I sit up for a sec and get a drink?"

"Sure."

Upright on the laid-out dentist-style chair, Eret took a long swallow of water and twisted to see his half-finished ink. The ocean and horizon were along his side, wrapping around to a pirate ship that took up much of his lower back. It was his biggest tattoo, and probably his most stand-outish after the traditional family one Eret had on his face. His others included a dragon skeleton on his thigh, a vampire bat on his other hip and a skull floating in space on his chest.

As Eret joked, it was a good thing Hiccup enjoyed his partners eccentric or perhaps eclectic taste in body art. Despite all the 'scary' designs inked on his skin, Hiccup knew full well Eret was the softest, kindest and sweetest guy he had ever met. The skull tattoo hid scars from an ex boyfriend who had attacked him, but it hadn't changed the gentle giant that Eret was. He had some mental scars left behind too, but he wasn't jaded. Trusted Hiccup as Hiccup trusted him.

They loved each other, complimented each others traits and coexisted very well. The fact they had sex with other people had never detracted from that. There was no jealousy or secrecy - they found someone attractive, got it out of their system and always, always went back home to each other. That was probably why they would never have a third permanent partner - it wasn't out of the realm of possibility, but Hiccup couldn't imagine anybody who would fit perfectly with the two pieces already there.

As Eret laid back down to let the artist continue, Hiccup laced his fingers through his boyfriends with a smile. The studio that smelled of disinfectant and vibrated with the constant buzz of tattoo guns was an accepting place, never batted an eyelid at the gay couple. Some of Hiccup's art was even on the walls, having been the one to design a couple of Eret's tattoos and often doodled to pass the time when Eret had a long sitting.

"Alright my man, you are done. Sat like a champ!"

A few cleansing wipes later to remove excess ink and - temporarily - blood so Eret could look, the man stood up and twisted his upper body in the mirror. There was visible swelling, the skin around it puffy and reddened, ink and drops of blood staining the waistband of Eret's 'tattoo day' shorts. The colouring was exquisite, Hiccup's artistic eye scanning the linework and shading happily.

"Looks great Eret."

"It had better. Want to wrap me up before I bleed everywhere Mac?"

"Sure. Make sure you take this off when you get home, let the air get to it. It's too big to keep wrapped for too long, you'll just sweat all over it."

"I will. Shower tonight. Slather myself in so much tattoo cream Hiccup can smell it in his sleep."

"Yeah. You're usually a quick healer anyway but this is your biggest piece, don't be surprised if it takes longer to heal than you're used to."

Eret took it all on board, covered in cling film for the trip home where he would be relegated to laying on one side for at least a week while he healed. The weeks he was healing from tattoos were generally the time they got extra creative with sex positions, or else when Hiccup looked elsewhere.

That was another thing he enjoyed about their open relationship - while he was hugely attracted to Eret, their sex drives were not a constant perfect match. If one wasn't in the mood, there was never resentment. They went and sated an urge, then came back to their love. As far as Hiccup was concerned, their relationship worked for them just fine and the biggest downside was probably the crazies the morning after. But that could surely happen to single guys too.

He washed his hands and helped Eret peel off his cling film wrapping, then gave him a couple of clean towels to put on the chair before he sat on it. Hiccup was about to sit down in his own seat when he heard a noise outside in the hallway of their building. Naturally curious, Hiccup stuck his head out of the front door.

"Get lost ya fairy boy!"

Jack, their grumpy and not-gay-friendly next door neighbour spat, but Hiccup noticed there were boxes in the hall and buff (he might have checked a couple out) worker men carrying furniture.

"Are you moving Jack?"

"Aye! Getting away from your kind."

Hiccup rolled his eyes, winked at a workman who looked very confused and closed the door behind him. He relayed the info to Eret, handing his boyfriend a refilled bottle of water on his way to his own seat.

"So we'll get a new neighbour?"

Hiccup nodded.

"Looks like. I mean, we don't know our neighbours now so it won't make much difference."

"With any luck the new one won't shout homophobic slurs in the middle of the day... but yeah, you're right. Won't change much."

-HTTYD-

If Hicretstrid isn't your game, there'll be a Heathcupstrid story in the future. After this is finished, that is. Which won't be for a while. But it'll happen. Promise.

Chapter two might be soon, might be ages. As ever I'm an erratic mess when it comes to update schedules.
