Some while ago, a good friend got a slightly creepy prompt; something about Hiccstrid spicing up their sex life by inviting Eret in – only for Astrid to then leave Hiccup for Eret's enormous dick. There was more to it that I thankfully forgot by now, but it made us all shudder.
However, it inspired me to write a counterstory, something that starts like that prompt but then goes into another direction.

Also, this story features a certain HC of me and a friend, that Eret is something like the Captain Jack Harkness of Berk. Ready and happy to jump everything and everyone, but with respect and only in consense of everyone involved, endearing friendliness, and always an amused twinkle in his eyes.

I plan to have this finished in three chapters. It also could turn into four though, we'll see.

Hope you enjoy! ;)

Hiccup wasn't really surprised when, after the council meeting was over and everyone left the Great Hall, he got pulled to the side by a pair of small but strong hands. In fact, he'd expected nothing else. During the entire meeting, Astrid's eyes had felt like burning coals on his skin, mentally undressing him at any moment, and this certainly wasn't the first time she wasn't patient enough to return to their home before she jumped him. No, not at all.

"Gods, I thought old Spitelout would keep on talking forever," his wife groaned as she opened the belt that held his trousers with sure and quick movements. She had him pinned against the wall of the stairs that led up to the Hall, not a place anyone could easily see but still anything but private. But that, too, wasn't a surprise.

At first, Hiccup let her do as she pleased. She pulled his trousers down just enough to free his semi, and he couldn't suppress a pitiful groan as she dropped to her knees to suck and tease him until he was fully erect. But once he had enough of that admittedly divine treatment, he pulled her back up on her feet, a little rougher than necessary but he knew she liked it that way. With one deft movement, he turned them around until it was she who had her back pressed against the stone wall, and pinned her there with his entire body pressed to hers.

"You're horribly impatient, do you know that?" he growled, letting out another groan when his hand wandered beneath her studded skirt and found her bare and dripping wet already.

"Not my – fuck! – my fault," she gasped when his fingers slipped inside her. Gods, she was a gift. "Nobody told me sex is that much fun."

Chuckling to himself, he kept tormenting her a little longer. Slowly he moved his fingers in and out of her, taking his sweet time to enjoy having her like this; the slick slide, how her eyes glazed over with undulated lust, and all those wanton little moans she gave in response to him fucking her on his fingers. Every now and then, he swiped this thumb over her clit, making her shudder, until her frustrated whine told him that he would be playing with his health if he continued like this.

He withdrew his hand and silenced her sounds of impatience by pushing his fingers into her mouth, making her taste herself on him. Her sucking at his digits and humming at the taste quickly made him just as impatient as she was.

Eager to be inside her, he hoisted her up with a few deft motions, her legs quickly wrapping around his waist, and without any more preamble, he buried himself in her scolding heat.

"Oh, fuck!" Astrid moaned, loudly, and let her head fall back against the stones. Her hands clutched at his shoulders, and Hiccup knew that, even with his tunic between her fingers and his skin, he would keep visible marks from this encounter. He was looking forward to it.

For a couple of minutes, Hiccup simply enjoyed the sight and feeling of her; her flushed skin all the way down to where it disappeared beneath her flimsy vest, her dazed eyes that wouldn't register anything of their surroundings anymore, her choked moans and sobs when he thrust particularly hard, and, of course, her silken heat that always felt as if she would suck him in to never let him go again.

Gods, how he loved their heated trysts! Marrying Astrid had been a dream come true, but never in his life had he been able to imagine how actually being married to her would be. Because it was amazing! Living with her was easy, effortless, and always such fun. They worked perfectly together in some aspects of their lives while they equally perfectly completed each other in other aspects. But without a doubt the biggest surprise had been the sex. With them both having had practically no experience before, they'd dived head over heels into this adventure, and it was an endless roller coaster ride ever since. There was nothing they were afraid of trying, the wilder and crazier the better. For once, Ruffnut's countless escapades with passing sailors and her loose mouth had actually turned out to be a blessing, if only to give them ideas about what they wanted to try next.

But lately, Astrid seemed to have found a new favourite. She just loved to have sex out in the open, in places that couldn't by any means be called private – and Hiccup had to admit that he rather liked it too. The danger of getting caught. The thrill.

"Imagine someone finding us here," he grunted, playing into this fantasy. The thought made them both groan, his fingers on her rear twitching just as she tightened around him. He couldn't even say what it was, but just the idea of someone else being involved in their sex life, even just as a watcher, made him almost come on the spot.

But he could tell that Astrid wasn't there yet, that she needed a little more. So he leaned closer and whispered into her ear, "Imagine how Fishlegs would react if he found us like this. He'd turn pale all over, stammer, and stumble backwards to flee and try not to look too closely."

Astrid giggled breathlessly, and the way that made her tighten around him nearly was his undoing. "Or Snot," she suggested. "God, how jealous he would be. He'd turn bright red, with anger and lust, and probably run to jerk it behind the next tree."

Oh, now that was an intriguing thought. Not that Hiccup really needed that sort of validation – not after all these years into his relationship with Astrid, not with them being happily married, and certainly not with her carrying a sweet little secret beneath her heart by now – but the idea of rubbing it in to Snot... he kinda liked it!

"The twins would probably just cheer us on," she went on in that wonderfully breathless and distracted tone that threatened to rob Hiccup of all senses. She was close now too, so he put in more effort, thrusting harder and deeper and tried to hold her with one hand only to rub her clit with the other. "And Eret... mmh, yes, don't stop. Ooohh..."

"Eret wouldn't be shocked at all," he gasped, the words dropping off his lips without even thinking about them. The ex-trapper definitely wasn't new to sex, and pretty much the entire village knew that by now. "He'd probably ask whether he can join in."

Unbiddenly, a picture appeared in his head, just as Astrid came with a beautiful little cry, with her fingernails clawing at his shoulders and her walls squeezing sense right out of him. He followed her into bliss, his desperate grunt muffled by biting into her shoulder – and with the image of him watching as Astrid got fucked by Eret in his mind's eye.
