Apparently Tryst inspired this prompt... I'm just happy to get Valcup prompts.

This was knocked out pretty quickly, so sorry it's a bit of a rush job.

-HTTYD-

"Hush, someone will hear you."

"Don't stop!"

Hiccup bit her thigh in admonishment, watching his mothers head fall back, felt her hands reach and clutch at his shoulders. This was, by far, their riskiest behaviour so far... not counting that time they had sex in the kitchen while his father was napping only one room away.

Stoick was one room away now, but so were a few dozen other people. It was a town hall get together, where nearly every resident of the entire village they lived in was in one building. Food and drink and conversation abound...

And Hiccup had convinced his mother to steal away to a store cupboard in the next room to fool around. Unable to resist the opportunity when he saw the boxes stacked at ideal height, Hiccup had taken to his knees to go down on her. Valka wore skirts often for good reason.

Hands clutching his shoulders, carding through already messy hair, Hiccup resumed stroking his tongue between his mothers trembling thighs, delighting in her musky taste and muffled moans. His fingers gripped at slender limbs, her skirt bunched up and starting to fall over his head so Hiccup could see even less, could only go on taste and smell and touch, everything surrounding his senses, and it was all his mother. Valka moaned weakly, begging Hiccup to take her.

Who was he to deny his mother?

There wasn't much light in here, only a tiny window at the top of one wall allowing a minute amount of sunlight in, but Hiccup knew his mothers face, body, soul in the dark. She tugged him to stand, kissed his wet face and licked his lips lewdly, ignorant of or enjoying the taste of her own arousal there. His trousers fastening lasted only seconds beneath her eager hands, Hiccup the one to muffle a cry in her shoulder as she gripped his shaft, stroked Hiccup's swollen cock.

"Easy mom, or this'll be over too quick."

He smirked to himself as she bit her lip, stifling her whimper at the word 'mom'. Valka responded in such an erotic manner to that word, and Hiccup hungered for that reaction constantly. She didn't let up her attention to his cock, using the grip to try and pull him closer, to guide her son where she craved him most. So wet, so hot... Hiccup sank into her willing embrace, feeling like the air was forced clean out of him when Valka squeezed, clenching her muscles around his cock.

They were not usually so quiet, but today they had to mute their usual vocalisations of how much they enjoyed their incestuous relations. Valka clutched his back so hard he felt nail marks on his back through his shirt, her legs wrapping up around his waist and hips to anchor herself against his body.

Hiccup knew they needed to be quick, but gods he wanted to savour the sight of his mother, her flushed cheeks and bright eyes, the way her jaw went slack and how her lips were slightly swollen from their feral kisses. No matter how many times they came together, the primal need Hiccup felt for this woman had yet to fade. He ached to bite and bruise her skin, leave marks to claim her but he knew he couldn't, knew that tonight she would be in bed with her husband.

His father.

So Hiccup held her tighter, fucked her harder and felt Valka mark him in return, biting at his shoulder to quiet her cries as she came for her son. Not at the peak yet, Hiccup kept moving, heard Valka make those soft little breathy moans as she took every thrust perfectly, the quivers of her climax dying down but he found his own bliss inside her. She cradled him, petting Hiccup's back and hair with little kisses peppered over his face.

Valka cooed as Hiccup pulled out, loathe to be parted from her but she stroked his jaw, kissed him softly and Hiccup's heart ached with how much he loved his mother. He reluctantly returned her underwear to her, which Valka slid back on with a breathless smile.

"This was dangerous."

"So? It was hot."

She rolled her eyes fondly, but allowed Hiccup to kiss her again, knowing they had to go back to socially acceptable mother and son outside that door. It was always tough to do so right after they were intimate, when Hiccup wanted nothing more than to curl up with her, cuddlimg and kissing playfully as they simply enjoyed their close, twisted bond with each other.

Hiccup left first, confirming the coast was clear and Valka excused herself to find a bathroom, leaving Hiccup to try and straighten himself out. His clothes were rumpled and there were dusty scuffs on his knees, his hair probably more impossible than ever and he could feel her saliva drying on his mouth. Hiccup reluctantly wiped it, did his best to fix himself up and headed back out to where the rest of the villages occupants were.

"Where you been lad?"

His father asked, giving Hiccup's slightly ruffled appearance a slightly disdainful once over.

"Went to the bathroom? Got lost, fell over, found it."

Fucked my mother in a storage closet.

"Ah. Where's your mother?"

For all his complaints Hiccup and Valka were too close, all his comments of how Hiccup was a "Momma's boy", Stoick always asked Hiccup first where the woman could be.

"Think I saw her heading to the bathroom on my way back."

To clean her son's come from her thighs.

"Right. Right."

Hiccup escaped his father as soon as possible, still tasting Valka on his lips and feeling his cock twitch already. Popping a boner in front of his dad wouldn't be ideal. When Hiccup saw his mother enter the room again, he could see the crease in her skirt where he had pushed it up, the stray hairs that curled from being dampened by sweat, the fading flush on her neck. She found his eyes across the room, offered him a smile that Hiccup had to hide in his drink when it wouldn't leave his face.

Maybe these village parties weren't so bad after all.

I did say rush job, but here is some Valcup smut!
