*pile of active stories demands attention*

*pushes them away in favour of more Valcup smut*

This one does follow the last one, but that's not always going to be the case. This one also lacks much backstory. It's just filth, really.

-HTTYD-

Sick. Illegal. Disgusting.

Those were the words Hiccup knew others would ascribe to what they did. Sick for him to crave her, illegal for him to fuck her. Disgusting that they dared enjoy it.

Easy. Natural. Perfect.

Those were the words Hiccup used to describe what was happening.

The dam had burst. Their walls came down. The lovers could deny each other no longer. It was the easiest thing in the world for Hiccup to accept his mother as his lover. It was the most natural thing in the world for their bodies to twine, Valka's moans soft against his ears. It never occurred to him that the way she snuck him kisses, the way she had with sweets when he was little, while his fathers back was turned was wrong.

It was perfect to lie next to her, caressing skin damp with sweat afterwards, when his mother was soft and lazy with the glow of satisfaction. Valka was such a beautiful woman, her long torso and lithe limbs melding against his own effortlessly.

"I love you mom."

Her lips pursed slightly before smoothing out. He still noticed, the last couple of weeks spent exhaustively learning every flicker of pleasure, pain, joy and hunger across her face.

"What's wrong?"

Valka turned away slightly before she answered, and he hated the sight. It was different to how she arched her neck to his kisses on the smooth skin.

"I wish you wouldn't call me that in bed."

He frowned, unhappy.

"Why? Are you worried I'll suddenly realise who you are and leave?"

His mother shrugged, still not meeting his eyes. His stomach felt cold with the next thought, fearing that she could change her mind about him.

"What is it then? Do you not like that I'm your son?"

She shivered ever so lightly. Hiccup contemplated it for a minute, fairly certain it was not a shudder of disgust. He remembered their first time with his own shiver of delight, when Valka had uttered the words "make mommy come". His cock twitched against his thigh, starting to swell with the memory alone.

"It's not that."

"Good. Because" Hiccup took a chance, hoping his instincts were right as he slid his body against hers "I love that you're my mother. And you didn't seem to mind when you were begging me to 'make mommy come' before."

Valka bit her lip, whimpered softly and Hiccup kept pushing, wanting her to admit it got her hot like it did him.

"You're the Jocasta to my Oedipus mom. It's fucked up, but I love that and I want us to be fucked up together."

She finally looked back up at him, pupils dilated and a gorgeous flush spreading over her cheeks, her neck, her collarbone. Her hand came up to stroke his jaw, her touch leaving a tingle buzzing on his skin.

"My son..."

Valka trailed off, possibly helped by Hiccup caving to the urge to cover her mouth with his own, hungry to taste her kisses.

"My mother."

Her breath hitched, hips arcing slightly to feel him hardening against her and Hiccup groaned, thrust against her soft abdomen. He had once grown there, incubated within her. The body that had given him life now filled him with primal lust, and it was reflected right back at him in her wide green eyes. Eyes Hiccup had inherited. He kissed the thin lips she'd passed to him too, nuzzled at a familiar jaw structure.

"Tell me it doesn't bother you I'm your son."

He needed to hear it. Her breath caught, then Valka was pushing Hiccup on his back and straddling his narrow hips. She leant close, whispered against cheek.

"It bothers me I'll never hear that word and not think of this."

His mother ground against his growing erection, coating him with her own arousal and earning Valka a guttural groan from her son. Hiccup gripped at her soft thighs, thrust up against her to win his own moans from her throat. Valka curled inward, gasping sharply and Hiccup wondered if this acute need would ever wane, or if he would always crave to be inside his mother so fervently. It was like a sharp ache, gnawing at him until they were one again.

"I'm gonna have to call you mom in public, knowing I can't tell anyone how hot it makes you in bed."

She quivered again, fingers tightening where they'd rested on top of Hiccup's hands on her thighs. With Hiccup's erection fully hard again, Valka raised herself up until she could seat herself on his cock, sliding down and even after the countless times they'd come together since the first, Hiccup had not yet adjusted to how intense it felt.

"Gods mom" he choked with pleasure as she tightened around him "uhh- fuck you're wet."

Valka hummed, seeming to be savouring the feel of him slotting inside her.

"All for you son."

Hiccup growled, thrust up and smirked as Valka had to scrabble for grip on his forearms for balance. Oh, but she took up the challenge and rode him hard, gorgeous and wild as she fucked herself in quick, sharp thrusts. Hiccup clutched her thighs, tried to match her rhythm and while he felt he came up short, Valka responded to her sons thrusts with heated moans, gasping his name and leaning forward to kiss him hungrily until their ragged breaths made it too difficult.

"That's it Hiccup... gods you feel so good son."

She clawed at his chest, short nails leaving only red lines in their wake rather than broken skin but the exquisite burn stoked the fire in his belly all the same. Fearing he would come too soon, Hiccup grabbed her hips tightly, stilling Valka and she growled at the restriction. He switched their position, slipping back between her thighs and lifting her leg up higher, knowing it would let him slide deeper.

Valka thrashed, whined and swore with every thrust, pushing back against him until Hiccup was dizzy with the heat between their bodies. She got demanding when she was close, a fact Hiccup was intimately familiar with and deeply enjoyed. He loved Valka's feral lust, how she got when she would do anything if it meant Hiccup would make her come.

With a low growl that might have been his name once, Valka fisted the sheets and arched her back, almost bent in half as she spasmed on her sons cock. He thrust leisurely as she came, enjoying the unique sensations and the way she was left loose, sated. Mother sighed breathily for her son, cooed for his gentle motions until he pulled out, stroking himself to climax as he spilled over her belly again.

He came inside her more often than not, but Hiccup knew if he left her messy, Valka was more likely to shower soon after. And that meant joining her in the steamy space, depending on whether they used the bath/shower combination, or the cubicled one that Stoick could not fit in - hence the bath/shower fitted.

"Such a filthy boy."

Hiccup smirked, softening cock twitching as Valka ran a finger through his come, held his gaze as she licked his taste from her own skin.

"Blame my mother" Hiccup leant over her, ignoring the mess to kiss tempting lips "she lets me get away with anything."

See? Just shameless smut. But I needed it.
