I have a mighty need for Valcup smut and as the only one who writes it I guess I have to write my own.

Luckily, I got a Mommas Boy prompt.

"That's it Hiccup, keep going son!"

Gods, she was addictive. His mother spread for him anytime, anywhere and Hiccup was utterly hooked. Valka seemed equally affected by the intensity of their physicality, and if there was a better sight than his mother in the throes of climax, Hiccup hadn't discovered it yet.

Valka bit at the bedsheets to try and quiet her desperate cries, pushing back on Hiccup's cock where he fucked her from behind. It wasn't ideal since he couldn't see her face so easy, but he'd quickly discovered his mother had some of her more explosive orgasms in this position. His cock throbbed, the view of it slipping into her wanting body a sinful indulgence and Hiccup keened, sweat running down his back and damp under his hands on her hips.

Her back arched, hands climbing the headboard until Valka was almost upright. Hiccup briefly wondered why, but judging by the way she moaned and swore the new position was working it's magic on the wanton woman. The sound of skin meeting skin was loud and filthy and Hiccup loved it, sped his thrusts a little more until his mother melted to a quivering wreck before his eyes, muscles clenching rhythmically at his cock.

Hiccup held her as she went lax, felt her soft and pliant as she twisted to kiss him. Hiccup indulged himself in heated lips, slipping his tongue in her mouth to earn those little gasps that echoed in their kisses. Valka noticed he wasn't done yet, rocking back into him to indicate he could continue. Feeling her soft, plush rear pressing against his lower abdomen, Hiccup had a different idea and pulled out.

"Son?"

"Lean forward. I wanna try something."

Never hesitating to let Hiccup have his way with her, Valka complied and noticeably twitched when he grabbed handfuls of yielding curve. He laid his cock along the crease of her ass, copious wetness from her climax coating his shaft for lubricant as Hiccup thrust. It wasn't better physically than the soft heat that had been wrapped around his cock moments before, but the visual as he squeezed the cheeks together and watched the swollen purple head reappear with each thrust was hot as Hel.

"Fuck, you feel good everywhere mom."

Valka whimpered softly, leant forward and arced her spine to raise her backside in the air a little more, giving Hiccup more leeway. With a few quick thrusts and needy whines, Hiccup spilled across her lower back and fell forward slightly, allowing his head to rest between her shoulders against her sweaty back, her endless and gorgeous hair all pushed forward during her leaning while he had her earlier.

Recovering a little, Hiccup managed to grab some tissue and wipe the worst of his mess from her skin before it got everywhere, allowing them to lie on the bed in a sweaty, debauched tangle of mother-and-son.

"What inspired that particular thing son?"

Valka traced shapes in the sweat on his chest. Hiccup ran gentle fingers over any bare flesh he encountered.

"You have a great ass?"

That earned him a playful flick to the ear that Hiccup pretended hurt terribly.

"You have developed such a filthy vocabulary."

"I'm sorry, but polite words don't do 'I have sex with my mother' justice. Nor would I want them to, and even you get a dirty mouth when you get hot."

"I do not!"

Laughing, Hiccup leant down to nudge her face with his until she leant back where he could kiss her.

"You are a liar."

The sex was indescribable, beyond earthly words but this was Hiccup's favourite part. Playful giggling and cuddles and just generally being so comfortable around each other. He loved the way his mother laughed lightly against his mouth, smiling when he kissed her again.

"Gods I love you so much."

"I love you too Hiccup. My beautiful boy."

They cuddled and kissed and soon dissolved into a vicious tickle fight. Breathless with laughter, Hiccup managed to pin his mother to his bed, Valka's cheeks flushed and doe eyes bright with joy as he claimed victory kisses from smiling lips. Her skin was more sensitive than usual from being tickled, gentle caresses raising goosebumps and Hiccup tasted breathy gasps in her kiss.

Any further intimacy had to be put on hold as his phone rang, the illicit lovers separating as Hiccup reached for it with a groan - he was closer after all.

"Hello?"

"Hiccup? Where's your mother?"

His fathers voice boomed down the phone, and Hiccup was about to answer but the woman in question was currently kissing his thigh. He hadn't even noticed her moving.

"I don't kn-owww" Hiccup tried not to gasp audibly as Valka tongued his cock "I'm in my room drawing."

Squirming, Hiccup couldn't say anything for fear of letting on what his fathers wife was doing. And she knew it, emerald eyes sparkling with mischief as nimble lips pressed warm kisses along the underside of his shaft.

"She's not answering her phone."

Hiccup reckoned she hadn't heard it, given that Valka had been in his bed for the better part of the day.

"I'll go find her-rrr" she'd begun sucking ardently at his tip and Hiccup was in danger of whimpering on the phone to his dad "and tell her to check. She's probably out with the a-animals."

"True. Bye son."

"Bye dad!"

Hiccup just about managed to hang up before the phone fell from his hand, fingers burying themselves in his mothers bed-tousled hair as she ramped up her attention to his cock. He wondered distantly if they should feel guilty, but then Valka was climbing his body to kiss him deeply, the hair that usually framed her face tickling his cheek.

"Dad wants you to call him."

"He can wait. If it was important he would have told you."

That was an excellent point. Hiccup felt her slim fingers curl around his wrists, not registering her intent until he found himself restrained by the cuffs he'd used on her yesterday. It was a testament to how little Hiccups father frequented his bedroom that he hadn't bothered putting them away.

"Hey!"

"I'm not done with you yet son."

Hiccup pouted, even less thrilled when she covered his eyes and he could neither see nor touch her.

"Mom! This isn't fair!"

"Hush now."

A finger pressed to his mouth in a silencing gesture, then the warmth of her body vanished altogether and Hiccup frowned, turning his head toward the sound of her moving. Her weight sank the mattress next to him, so he wasn't just abandoned. Valka gasped quietly, letting out little moans in soft breathy puffs. Was she touching herself when Hiccup couldn't see or help?

That was just cruel.

Something cool landed on his cock, making Hiccup jump at the sensation before squirming as his mothers hand joined it, smoothing and warming the oily substance along his shaft. Why was she putting lube on him? He didn't exactly fail to make his mother wet with arousal. Even so, it felt good and he thrust into her hand, jumping when she slapped his hip with her free hand.

"Still."

"But-"

"Hush."

She smacked him again, and Hiccup could clearly picture her mischievous smirk as he grumbled in annoyance. Her hand left his cock to make things even more frustrating, then she was straddling his hips and Hiccup was both very happy, and very distressed he couldn't see her. Something was different as she seated herself on Hiccup's erection, but he assumed it was the lube making everything feel slippery and strange.

Then Valka removed the cover on his eyes and Hiccup realised what was different, watching as his cock slowly vanished into her tight, gorgeous ass. His mouth fell open in shock; they had never even talked about this, though Hiccup wouldn't deny thinking of it. His mother really did have the most fantastic backside ever.

"Slow baby, mommy's never done this before."

"R-really?"

"Mhmm. Only you son."

Hiccup could only stare in disbelief, watching his mother as she bit her lip, moving herself tentatively so she wouldn't hurt herself. He did his best to stay still, not wanting to rush even though the tight muscles were squeezing tight to torment Hiccup's cock until he was almost mindless.

"Mommmm."

He strained against his bound wrists, wanting to touch her and pull her closer, wanting to kiss her in reassurance that he didn't want to hurt her. She winked at him, enjoying his frustration as Hiccup growled. She began to relax around him, her rocking motions obviously easier on her. When Valka leant down, Hiccup met her eagerly to kiss her hungrily.

"You feel so good in me son."

Hiccup whimpered, catching her mouth again and moving his own hips gently, testing if she could take it.

"Let my hands go. Please?"

He gave her his best puppy-dog expression. As a boy, it got him cupcakes. As an adult, it usually got him oral.

"Will you be good?"

Hiccup nodded eagerly, thrilled when she released his wrists so he could get his hands on her again. Gingerly sitting up, Hiccup wrapped his arms around her back, kissed her flushed chest and cupped his hands under her thighs to support her when she moved on his lap. Hands settled on his shoulders, Valka bracing herself on her son to ride him with a little more energy now she was adjusting to the new penetration.

"Love you mom."

"I love you too Hiccup."

Near-delirious as Hiccup was with the feel of her plush cheeks spread for his cock, pressing on his thighs with every downstroke, he still wanted to ensure his mother felt similar pleasure. She was moaning softly with each thrust, but Hiccup was immensely gratified to note the increase in volume and pitch when he slid his fingers down her soft belly to press against her clit, work their way inside her to stimulate the spots that usually made her come. She was wet on his fingers, telling Hiccup her enjoyment wasn't faked and he was glad.

Valka picked up speed, though Hiccup ensured he never got rough with her as his cock slipped in and out of her with surprising ease; she took him so well, like her body was designed for him. Her body had designed him, after all. Maybe the womb had known what the woman would want one day. He moved his fingers just as fast, feeling the way her body tensed, spring coiling tight within until Valka clutched at his back, moaning and swearing in his ear.

"Fuck me baby... love you so much."

Hiccup would have pointed out she was swearing, but he couldn't speak. He was too busy holding out for her, soon blessed with the rhythmic spasms of her muscles and a new reward in the sudden squirt of fluid against his belly and the higher-than-usual frequency of frantic moans. Her nails raked over his back as she cried out, hips and thighs flexing again and again until she slumped, gasping.

"Gods Hiccup..."

He hoped she wouldn't mind him coming inside her as he couldn't stop, holding her tighter to him as a last few thrusts took Hiccup to Valhalla with a low groan. Valka waited until he started to soften to move off him, face tight with pain and he immediately felt guilty.

"Are you hurt?"

"Sore, but that's normal. Honestly Hiccup, that was... sensational."

"You uh... I don't know what to say."

Hiccup indicated the sticky mess all over his stomach, thicker than her usual wetness and there was a lot of it. Valka looked over from where she was sinking into the bed, chuckled lightly.

"I'll explain it to you later son."

"You want a massage? I don't want you in pain."

His mother shook her head, rolling herself to a stiff seated position, standing delicately.

"I need a bath."

"Is that an invitation?"

Hiccup asked hopefully, wanting the pleasure of washing her. Hands on her skin, touching and rubbing as she languished in his arms...

"Well, you are quite messy..."

She held out a hand, and Hiccup stood up to take it eagerly. Then looked at his ruined bedsheets, deciding they could wait. It was bath time after all.
