Accidentally got absorbed in a Hiccstrid story... It's funny how I don't even really ship that. Any who... Back to this!
-HTTYD-
Their night alone had been great - and long - and Astrid had loved the time alone with her husband, but she couldn't deny feeling better when Valka and their dragons came back. Hiccup kissed his mother in greeting, then Stormfly and Toothless were both all over their riders excitably.
"Yes Toothless, I missed you too!"
"Stormfly!"
Valka chuckled as she watched them, joyful at their bond with the beasts.
"What did you do with your night mom?"
"I was in the nursery, surrounded by dozens of baby dragons all night."
"That almost sounds more fun than our night."
Hiccup slid arms around Astrid's waist, nuzzling her neck with a grin. He was exceptionally tactile that morning, cuddling and kissing her constantly and she quite enjoyed it.
"You eaten yet Valka?"
"Not yet, these two were very enthusiastic about getting back to you."
Hiccup took the hint, kissing Astrid's jaw again and heading over to start prepping breakfast. Not that he was short of options - their living room had been filled with food and gifts between them getting home and coming down. Astrid hoped nobody had been listening to them fuck... she would kill them.
The two women sat on the sofa, closer together than Astrid knew they would have done after first meeting. Valka didn't initiate anything, but when Astrid swallowed her nerves and took the woman's hand, she squeezed it in return and rubbed her thumb in small circles on the back of Astrid's hand. Hiccup glanced over and smiled, then resumed stirring eggs and chunks of yak bacon into a bowl. Astrid was ravenous after their exhausting night, stomach growling at the smells released when Hiccup dumped the mix into a frying pan.
Three steaming plates of 'messy eggs' as Hiccup called them - scrambled sloppily, all over the plate and utterly delicious - with warmed bread and yak butter found their way to the table, and Astrid was almost disappointed to have to let go of Valka to eat.
"Gods, I may chain you to the house and make you my househusband, never to leave me so you can cook like this forever."
Hiccup chuckled, eyes alight as he looked between his mother and his wife with smiles as they devoured the delicious breakfast. Her stomach felt almost overfull as she finished, watching as Valka cleared up and went to rinse the dishes while Hiccup cleaned up his food prep area. Astrid was shooed off when she tried to help, so sat on the sofa pouting unhappily.
"Mom? You want this too?"
Astrid looked up, confused as Hiccup held up something to Valka. She nodded, flashing Hiccup q coy grin he smirked in response to. Astrid still didn't click until Hiccup dispensed the water steeped with herbs into two cups, held out one to Astrid while Valka took the other. She recognised the unpleasant smell immediately. Hiccup was making them their anti-pregnancy tea.
"Ugh, why can't they make something that doesn't taste of yak piss?"
"They did, it's called celibacy."
"I will hurt you Hiccup."
He chuckled at her again, holding his hands up in surrender as he dispensed fish into bowls for the ever-so-patient dragons hanging around. Astrid let it cool a little, then downed the foul tea in two big swallows, cringing.
"Gross."
Astrid stood up, intending to get another drink that removed the taste from her mouth. Hiccup stopped her, pushing her back into a seat and Valka sat next to her, holding out a handful of sweet leaves.
"I can do things for myself you know."
"I know, but I only get today off, and I'm intending to make the most of having the time to take care of you."
She couldn't really deny his pleading eyes, sighing and shoving the sweet leaves into her mouth. They worked to remove the lingering taste of the tea, which alleviated much of her frustration and Valka's fingers trailing along the back of her neck had Astrid melting back into the sofa.
Astrid was glad nobody was asking what the thing budding between she and Valka was, because she wasn't sure there were words, and letting it develop naturally was all she could think to let happen. Valka seemed content to make the first moves mostly, which worked fine to Astrid as she was still adjusting to the possibility that their separate twosomes would become something else.
Soft fingers played over the base of her neck and in the hair that had escaped her lazy braid that morning. Astrid leant into it, humming to herself and feeling Hiccup's eyes on them, though he said nothing. Valka's tactile affection apparently included Astrid too, as she didn't stop touching Astrid even as her body took on a mind of it's own and ahuffled closer to enjoy the gentle caresses on her neck and scalp.
"She never does a cat impression for me. Is this a secret power?"
Astrid didn't realise her eyes were closed until Hiccup's voice invaded her world, scowling without opening her eyes to answer.
"Yep. She's less annoying than you."
Both mother and son laughed, neither disturbing Astrid as she stayed relaxed and prone. Full after breakfast often made her a little lazy; she didn't often have such a heavy breakfast but Hiccup's wedding-celebration meal was too good to resist. Her muscles were lax, pliant as Hiccup lifted her legs and sat beneath them, so she was laid between he and Valka. Her cheeks warmed as she considered other permutations of that.
Hiccup rubbed his thumb back and forth across her still-bare knee, but otherwise left her to enjoy the soft silence. They were forced to pull apart when the door knocked, Valka letting Hiccup take her place under Astrid's head while the Haddock matriarch answered the door.
"I'm under orders... I think, I'm still learning Gothi-talk. To bring this to the happy couple. Not that I know what it is."
Eret was immediately obviously nervous at Valka's appearance - the two no longer butted heads often, but he was wary of upsetting Hiccup's mother. He waved at Hiccup and Astrid where they laid together; making Astrid glad she had opted to wear a tunic rather than just her light shift.
"Yep. Enjoy your day off chief!"
"Thanks Eret. Is ever- mmph!"
Astrid placed a hand over his mouth, cutting Hiccup off.
"No work talk. Leave Eret before he tries to chief again."
Eret laughed, waved again and left. The door closed again, returning them to their inner sanctuary. Valka started laughing as she investigated the cloth bag Eret had delivered, a full and hearty laugh where she placed her hand on her stomach and bent slightly. According to Hiccup, she did that from the day they met.
"That's not what I think it is is it?"
"I rather think it is. Seems our venerable elder wants to ensure the continuation of the Haddock line, and fears for your ahh... performance."
Hiccups face reddened as Astrid joined in the amusement, realising Gothi had sent Eret to deliver aphrodisiac mix to Hiccup - something that would make him hot and ready for a couple of hours at a time. Not that Hiccup struggled in that department, but she supposed they could have quite some fun with it. Especially when he had two of them to keep satisfied.
"Are you two quite finished mocking me?"
Still snickering, Astrid tried to reassure her husband.
"Babe, I'm not worried about your bedroom performance. You've been keeping up with both of us for months. It's just hilarious to imagine Gothi worrying about whether or not you can get it up."
Rolling his eyes, a more indulgent expression took over his face as the two women continued laughing to themselves. Seeing how much Valka positively lit up when she laughed, huge green eyes glittering in her flawless face, Astrid kept seeing all the ways Hiccup could have fallen for her. She was playful and happy, sweet and caring. Not to mention; she and Hiccup were both beautiful, her the cloth from which Hiccup was cut though his features were a little more anangular and masculine.
Astrid wondered when she had gone from simply accepting to no longer caring that they were mother and son.
"I really hope nobody else knows about Gothi doing that. Batty old woman."
"If they ask I promise to say there's nothing wrong with the little Hiccup. And punch them in the face."
Hiccup grinned, kissing Astrid when her face was in reach. He licked teasingly at her lips, tasting the sweet leaves Valka had given her and humming happily; Astrid's heart quickened when she realised Hiccup could taste his mother in his wife's kiss. She lost track of her body moving until she was in his lap, firm hands gripping her hips.
"See? Told you there was no problem."
A panting, gasping Hiccup smirked when Astrid alluded to the erection he was sporting by now. It was impressive, he should have been exhausted by the previous night but there he went again. Astrid on the other hand was still sore, even as she grew wet from the hungry kisses he bestowed on her.
"You ok?"
He whispered it against her lips, checking if Astrid was indeed still too sore for sex. When she didn't answer, he took a second to think, then smirked.
"Feeling adventurous?"
"What did you have in mind?"
Astrid could only assume Valka had already said she was up for blurring the lines, when Hiccup whispered hotly in her ear with a smirk and Astrid whined, biting her lip as images filled her mind.
"You don't have to, ok? The boundaries are completely yours to set Astrid."
"I want to. Is she-"
"More than."
"Let's go."
Hiccup's breath hitched at her eager tone, biting gently at her neck before they stood up. Hiccup went for his mother's room; Valka too. Astrid didn't, surprising them both.
"Are you sure about that? We don't mind."
"I'm sure. Come on, before someone gets here and sees your mother coming up with us."
The mother and son shared a surprised glance, then both followed her eagerly. Astrid knew she couldn't think too hard about what was happening or she would overthink it, letting it come naturally as Hiccup kissed his mother, lighting a fire in Astrid's belly as she watched the two. They stripped each other of their tunics, Hiccup's fingers next making short work of Valka's breast-bindings and caressing her breasts.
Astrid could only stare; Valka's breasts were bigger than her frame suggested, soft and plush as they yielded beneath her sons hands. They must have conferred telepathically - that was the only thing Astrid could think of as they both turned on her as one, pulling her onto the bed and removing her tunic with startling ease.
Before she could think too hard about being naked in front of Valka, Astrid was pulled into position by them both; her back against Valkas soft, warm chest as Hiccup shimmied down the bed to rest between her thighs with a smirk. Long arms wrapped around her waist, both Hiccup and Valka putting their mouths on her as one. Valka used one hand to turn her face enough, kissing her as Hiccup's tongue delved into her, stroking her clit.
Valka swallowed her moans, kissing Astrid so thoroughly her head was spinning, those teasing slender fingers stroking over the top of her stomach as Hiccup went down on her, watching the two women kiss with dark eyes as he gripped her thighs. Astrid was completely at their mercy and loving every second, feeling Hiccup suckle at her clit and press fingers inside her to add a fresh layer of utter torture to the sensations wracking every part of her body.
Just when she thought she could take no more, Valka's hand slipped upward and squeezed her breast, dragging firm, slow fingertips across her swollen nipple. Astrid shuddered, teetering on the edge of climax as Valka kissed her breathless, teasing her nipples as Hiccup dragged his fingers over the sweet spot inside her and dragged that talented, wicked tongue along her clit. Her muscles tightened all over, body pulled taut as the climax closed in on her.
Finally letting Astrid draw in a few laboured, gasping breaths, Valka moved her mouth down to Astrid's neck and sucked a bruise near her thundering pulse point, the final push that threw Astrid over the teetering edge, exploding between the two of them and clamping her thighs around Hiccup's messy, glorious head as she came.
Valhalla called her name as bliss ripped through her, leaving Astrid a lax, satisfied mess on the bed held up only by Valka's arm around her waist.
"Wow. I think the whole village heard that."
"Piss off Haddock."
Hiccup chuckled at her frequent post-orgasmic snark, crawling back up close to them and kissing his mother while still coated in Astrid's wetness, the sight arousing beyond what her body could handle and Astrid shuddered again, whining as her overstimulated body ached with pleasure.
Valka actually made sounds that Astrid could only call pleased, stomach bubbling with heat as she realised Valka was enjoying the taste of Astrid on Hiccup's lips. The two pressed closer, bare breasts on bare chest and that hunger the two shared; they had been focused only on Astrid, now it was their turn.
"Mm, hang on."
Hiccup pulled away from a pouting Valka to strip off his leggings, difficult to do over his prosthetic unless he had his legs hanging over the side, allowing room to manoeuvre. Still, it often gave a wonderful view of his bare butt as he leant over, then he would return naked as a newborn and it was always an appealing sight.
Astrid had 'caught' (she was no longer sure they weren't trying to get caught by her) Hiccup and Valka together more than a few times, but they were usually half-dressed fumbles with functional pushing aside of fabric. This would be the first time she saw Valka naked, but the other woman showed zero nerves of that fact as Hiccup grabbed her waistband, pulling the cloth material from her lower half.
"You got a preference Astrid?"
Hiccup's 'idea' had been twofold; he wanted to watch Astrid and Valka kiss while he went down on her, and then he had asked if Astrid minded watching he and Valka together. Having been considering how she could ask for that and getting nowhere... she had obviously agreed. They both waited with eyes on her, Hiccup's erection waiting to find it's place within his mother when Astrid told them if she had a preferred position to watch them.
Raking her eyes down their nude forms, Astrid couldn't help noticing how the two had similarities beneath clothes too; Hiccup got his hair colour from Valka, and that applied everywhere. Hiccup's fingers moved slowly between his mothers thighs, boosting her arousal as they waited and Valka's soft moans filled the air.
"N-nope, just do your thing."
The two shifted around without exchanging a word, somehow choosing the exact position Astrid had been too nervous to request as Valka got on all fours, pushing her hair over to one side so she could twist her head back to see Hiccup kneel behind her.
"Ready for me mom?"
Gods, that was the hottest thing Astrid had ever heard him say. Valka bit her lip, whimpering low in her throat as Hiccup dragged his erection over her, not pressing in as she clearly wanted him to. She pushed back against her son, head falling forward with a shocked moan as Hiccup buried himself in her body with one harsh thrust.
"F-fuck son, need you."
Astrid watched hungrily as Hiccup winked at her, grabbing handfuls of his mothers hips and rolling his hips slowly. It was hard to know where to look, Valka's lithe body quivering with the pleasure Hiccup gave her or Hiccup, face slack with pleasure and that mischievous Loki-grin all over him whenever he saw Astrid watching.
Valka moaned and whined with each of Hiccup's thrusts, shuddering as he hit her deep with the angle of his hips and her arms shaking with the effort of holding herself up as Hiccup fucked her. Astrid's fantasies of this moment did it no justice, something deep and primal about watching her husband take another woman like that so hot Astrid could hardly breathe. She was often too absorbed in the act herself to watch Hiccup's face, to fully appreciate the way his eyes fell closed and mouth went slack.
Hiccup stopped dead, winning a raw sound of complaint from Valka but Astrid could see his expression, realised Hiccup was planning something. He pulled out, shifting his legs forward and pulling his mother back into his lap. Fuck, Astrid could now watch everything as Hiccup's cock disappeared into his mother again and again, and watch Hiccup reach around to squeeze bouncing breasts. Valka's body was completely exposed to Astrid's eyes, long auburn hair falling around her as she fucked herself on Hiccup over and over.
There came a point where Astrid realised she knew how Valka sounded when she was about to come, choked moans and high pitched whimpers filling the air when Hiccup's face appeared to wink at Astrid, then reached down to stroke his mothers clit, sending her headlong into climax as she quaked atop Hiccup, thrashing in pleasure.
Hiccup's last few thrusts preceded his deep groans in the throes of orgasm, filling Valka with his come as the two crested the wave together right before Astrid's eyes. Valka twisted in his lap, kissing her son between gasping breaths as they came down from the high, crawling back along the bed in a spent, sweaty mess of limbs.
Hiccup kissed Astrid, smiling up at her and Astrid returned it. When Valka looked over at her questioningly, obviously checking that whatever they had done was not over her boundaries. Astrid did the only thing she could think of and kissed her, sharing a smile with her mother-in-law.
Hiccup eventually sat up, rubbing his stomach.
"Lunch?"
Astrid burst out laughing; it was so very Hiccup.
-HTTYD-
This is both the most challenging and the funniest smut I've ever written.
