So I got these mini - clusters of prompts from each section of a prompt list. Here is the smut ones... well, one.

"I missed you so much." + "I've been thinking about you all day." + "I really don't care. You still look hot and I'm trying not to kiss you senseless right now." + "Are you sure? Once we start, I might not be able to stop."

-HTTYD-

Hiccup dropped down next to her, surprising Valka slightly as she hadn't heard him approach. Still, it was a most welcome surprise. He leant in, dropping a kiss on her cheek. It was all they could risk; they were at a party. People could see them.

They were mother and son.

"You look edible."

He murmured against her ear as Hiccup drew back from kissing her cheek, and Valka had to hide her face in her cup, hoping people thought her flushed cheeks were from alcohol rather than arousal.

"Hiccup! Behave. There are people."

Shuffling closer and keeping a giddy sort of grin on his face - perhaps everyone would assume him drunk and giggly too - Hiccup leant in with an arm slung around Valka's shoulders, breath hot against her ear and she had to fight not to squirm.

"I don't care. You look hot and it's taking all my self-control not to kiss you senseless right now."

Valka shivered slightly, bit her lip to keep from succumbing to that very urge. Why had they agreed to come out tonight again? Hiccup was being terribly tempting and she could do nothing but suffer while surrounded by people who could know nothing of the way the two spent their nights - together, sweaty and entwined.

"Hiccup, please..."

"Spoilsport."

He dropped another kiss to her cheek, then let go of her and raised his own drink to someone looking their way, lopsided grin encouraging the idea he was simply a little intoxicated. Valka knew Hiccup had nothing more than cola in that cup, but nobody else needed to know that.

She shook off the thought that his mouth would be sweet and syrup-y, took a sip of her own slightly alcoholic beverage. It wasn't nearly enough to get her drunk, but it was her third and Valka was getting close to being tipsy enough that dragging Hiccup to the nearest cupboard to take him up on those kisses sounded sane.

No more alcohol for her tonight.

"Why are we here again?"

"It's your cousins wedding reception Hiccup."

He winked, letting Valka know he knew exactly that. She tried to ignore his suit, knowing she would not be able to stop thinking about how handsome he looked, how the material stretched over nicely broad shoulders, hugged at his tapered waist, strained over his cute, round bottom...

"Can we leave yet?"

Hiccup's voice broke her reverie, eyes burning into hers, clearly working not to follow the line of visible cleavage he had insisted on Valka's dress having. She felt a little... mutton dressed as lamb, but her very persausive son had been adamant it was perfect. Valka glanced at the clock, counting down how long they had been there, and what time an exit would seem rude.

"Half an hour? By then everyone will be so drunk they wouldn't notice us leaving anyway."

Those thirty minutes dragged on, especially when Hiccup wouldn't leave her side and all Valka could smell was his leather-musk aftershave, seeming to stick to her skin as they sat together.

"It's been half an hour. Let's go before I drag you into the alley out back."

As Valka felt a low throb of heat, she seriously considered letting him. Hiccup visibly contemplated simply taking her there in the car, but opted instead to start the engine, driving them a few minutes away before he pulled over, leant across and hauled Valka to him for a kiss. It was risky and stupid, but Valka could deny her son nothing. Especially when he kissed her like that.

"I missed you. All day. And then that bloody party, pretending... let's get home."

Eyes dark and chest heaving, Hiccup resumed taking them back to somewhere nobody could catch them. Flushed herself, Valka leant back in her seat, needy and wet and wanting the whole way back. The front door barely closed behind them before hungry mouths clashed, Hiccup tossing the jacket of his suit aside while Valka worked off his tie, all the while not caring about breathing enough to stop kissing. Dizzy by the time they came up for air, Valka found herself moved, bent over the stairs with her legs spread, her rear canted up and Hiccup behind her.

"I spent all day knowing you would be wearing this dress" he slid the green fabric up an inch, touch ghosting the back of her thigh "and thinking about how I'd love to do this."

The skirt of it was hiked up, left bunched over her back and Hiccup rocked into her, dragging his clothed erection over Valka's soaked underwear until she mewled and shuddered. He'd been thinking all day of her in this dress? Of having her this way? No wonder he'd been so keen to get away from people and have her. Not that Valka minded.

"Here."

"Really?"

Valka nodded, moving her hands up a step so that her wrists weren't bent uncomfortably, but she was still very much bent over for Hiccup's viewing pleasure.

"Are you sure? I might not be able to stop."

She heard the laugh in his voice, twisting to look over her shoulder, to play along.

"I can take it."

If it hurt her, he'd stop, but Valka thrilled in the dark heat of his gaze, the desire laced into his tone. Her briefs were slid over her backside, pushed down her legs until Valka could step out of them. Hiccup's zipper scraped as he opened it, other hand moving to test how ready Valka was, hissing at how aroused he found her.

"Fuck, mom, you're wet."

"All-oh, all for you son."

He growled, still-booted feet closing the minute distance until Valka could feel him hot and firm, piercing her inch by inch until Hiccup rested his hips against her ass, sighing as her body gripped at his cock in a bid to hold her son inside her. He would not be stilled though, gripping the top of Valka's thigh for leverage before snapping his hips back and forth. Valka choked on a moan, head falling forward when holding it up became too much effort, effort she needed to focus on feeling the exquisite bolts of pleasure running through her, the fire her boy inspired.

Hiccup fucked her quick and fast, knowing this would only be round one, and both needed to burn off the urgent, feral energy before they could go to bed and take their time, enjoy each other fully. Valka took every punishing, perfect thrust happily, moaned openly, displayed her passion and pleasure for Hiccup shamelessly. He repaid her efforts, leaning forward to let his thrusts nudge fully at that spot inside her, fingers worming their way under the rucked up dress to find her slick clit, stroking Valka inside and out until she could bear no more of his beautiful torture.

Her clenching, spasming muscles barely slowed Hiccup down as he kept going, dragging against her tightening body before he pressed back in, settling deep as he could to come buried inside her. Valka greedily enjoyed that sticky warmth, her sons climax leaving her feeling soft and sated even as he pulled out, their mingled fluids dripping down her thigh.

Hiccup helped her stand, cooed apologetically and kissed at the red marks on her palms. Valka waved off his concerns, leant down to taste his mouth again before curling her fingers around his, already planning the next round.

"Let's go to bed son."

"Lead the way."

-HTTYD-
