I know! I know! I got sidetracked with a lot of other Valcups, and neglected this one terribly.

Painting was much more fun with his mother, Hiccup knew, lamenting the lack of her as he swirled colour across the wall. Still, painting was fun anyway. Dabbing his brush in another colour, Hiccup mixed up the base blue until he had a more late-night look to the sky.
Setting aside this wall for them to paint whatever they liked on had been an amazing idea - the picture changed constantly, and they'd both come and go, adding to each others until the most weird and wonderful mixes combined. Her ocean view was darkened by his night sky, city lights in the backdrop to contrast even further. Various animals nudged and nosed at his legs, wanting attention or food or just to touch him.
"I can't pet you, you'd get covered in paint!"
"Somehow, I doubt they care."
Hiccup's heart leapt as he heard a familiar, beautiful sound - the voice of his mother, her head appearing around the door still clad in her outerwear from a trip to pick up supplies for their animals. Hiccup had wanted to go, but Stoick insisted on driving and Hiccup wasn't about to give his dad the chance to try and drag Hiccup to work with him that day.
"You're back!"
"I am. Mind if I join you?"
"Never."
Valka left to change into her painting clothes, then returned and soon they were mixing colours and stealing kisses, sharing smiles as they decorated the wall with fresh images. With green and purple splashes on her face, his mother looked colourful and radiant as she beamed when Hiccup caught her eye, offering a smile in return.
"Nice dragon. Not sure how many spend time on beaches though."
"Well, we do things a little differently around here."
Hiccup couldn't argue with that, letting his eyes slide over soft curves he would know in the dark, mapped with hand and mouth a thousand times or more.
"I better feed the beasts before they start licking paint or something. Come on you lot, lets begin the feast!"
Hopeful, a swarm of furry creatures followed Hiccup as he moved through the house to where mounds of food for many animals awaited, dispensing it into various bowls and holders until the sounds of gleeful chewing and snuffly breaths replaced frantic meowing of "give us the food!" at last. Hiccup headed out to feed the outdoor animals, aware of eyes on him right up until he turned and grinned at his mother.
"So, what else do you wanna do today?"
He knew the smile she responded with well, quite sure that whatever they ended up doing later would come after a spell in bed. Hiccup kicked off his outside shoes at the door, dumping his paint-covered overalls in their usual spot before chasing his now-naked mother to his room. Valka didn't try too hard to get away, and Hiccup had his arms around her before the door even closed behind them.
"There's some-oh, easy baby, mommy's sensitive..." Hiccup gentled his touch on her chest, curious "something I want to give you my love."
Hiccup turned her around to face him, tracing fingers up over her bare stomach and watching goosebumps rise on her skin.
"What's that?"
He couldn't really think what else Valka could give him; Hiccup was given many things by her, sometimes every day. She slid her hands up his arms, cradling his jaw.
"A baby."
Ok, he hadn't been expecting that,
"W-what?"
"Well, I'm not getting any younger, and I want you to be a father. If you don't want to-"
Hiccup surged forward, kissing the ridiculous, beautiful woman before him. How on earth could she think he wouldn't want that?
"I do, gods I do. Are you serious?"
Valka nodded, drawing him toward the bed.
"I'll stop taking my pill."
Hiccup growled, hands already groping at her thighs, her hips, his cock hard against her belly until they parted long enough for her to scramble up on to the mattress, flushed cheeks and heaving chest oh so tempting to him.
"Better get practicing then."
Gods, Hiccup was dizzy with arousal already at the thought of getting her pregnant. Valka spread her legs, reaching for him and pulling Hiccup to her. He gripped her thighs again, hauling her legs up against his chest and rubbing his swollen cock against her hot little clit, loving every tremor that rolled through her with each motion. Satisfied she was wet enough, Hiccup pulled back just enough to guide himself in to her, sinking into slick heat and only stilling when he bottomed out. He held her gaze, tugged her hips to make sure she felt him deep.
"Gonna put a baby in you mom."
The image of her growing, rounding belly and soft hips and swelling breasts as her body prepared to bear his child... it was enough to make Hiccup worry he'd come too soon, dragging himself back from the edge so he could make Valka come too. His mother moaned as he thrust, eyes falling closed as she fisted the sheets. Hiccup knew the position let him press deeper into her, which felt fitting given their end goal now. Not that Hiccup needed an excuse to want to come into the incredible woman spread out across his bed right now anwyay.
"So good, gods Hiccup..."
Her nails clawed at his back when Hiccup let her legs down, desperate to kiss her. They shared breath as they gasped, panting, green meeting green as they looked at one another, both teetering on the edge and racing to push the other over first in their never-ending contest. Hiccup wasn't going to last, not when he knew every time he spilled into her could now be the time that took.
Even so, he thought they'd probably make sure to get lots of 'trying' in all the same.
Hiccup came first, burying himself deep and feeling his hips jerk with each spurt, loving those sweet little sounds Valka made when she felt her son spill into her. Fumbling between them, Hiccup pushed up on his knees, thrusting while he was still hard enough to and rubbing his thumb over her clit. His mother shuddered through her own climax soon enough, which Hiccup remembered from a science book was helpful when trying to conceive. All the more reason to make her come over and over and over again, which luckily happened to be Hiccup's favourite hobby.
They cuddled together, stroking sweaty skin and kissing lazily as they caught their breath. Hiccup burrowed his face in her neck, nuzzling until Valka giggled.
"Love you mom."
"I love you too son."
Hiccup ran a hand down her back, squeezing a handful of her plush, gorgeous backside and feeling Valka press into him, heard her mewl in pleasure. His cock twitched; Hiccup thrived in his youthful energy and loved that his mother was able to keep up with him.
"I know it's only day one, but I think we should start as we mean to go on and keep trying."
Giggling, Valka rolled her eyes fondly but there was a playful smirk on her lips.
"I quite agree."

Practice makes perfect! I don't know why, but my headcanon Hiccup has a pregnancy will never be quiet!
