Disclaimer: I don't claim that this is how the characters, especially Hiccup, would behave. I'll say this once and from now on only laugh about whoever comments that he would never act like this. I know that and I don't think he canonically ever would. But that's not what this story is about anyway.
Instead, this is a What if story. What if Hiccup wasn't the kind and forgiving person we get to know in the franchise but is instead marred and changed because of the years of abuse and harassment in his childhood? What if he became twisted and hard and lost his sense of justice? What if he became… evil?
This is a Darkcup story, and I plan to write more in this verse, this story with a couple of chapters but also other stories and OS placed in the same verse.

Also, this story developed after a couple of prompts I got. I hope someone will like it.
2nd also: I spend some time analyzing the writing style of some authors I like and tried to adapt to that. Let's see how that turned out.

On the way back to the Edge, Hiccup was filled with excitement. He could hardly believe it but finally he and Astrid we officially betrothed; the celebrations with their parents and friends had been only yesterday. He glanced over to where she flew in her usual spot at his right, grinning when she returned his look. She was his now.

"Okay, everyone's off for the day," he declared as they landed at the stables on Dragon's Edge. The response was a general cry of excitement and judging by the mischievous grin the twins shared, Hiccup wasn't sure whether he wouldn't regret this tomorrow. But honestly? He didn't care. Not with what he'd planned for tonight. Not even the twins blowing up half the island would stop him now.

When everyone left, Astrid lingered a little longer, just as Hiccup had hoped. He wrapped an arm around her waist and pulled her closer, almost kissing her. Her eyes were gleaming just like always and she had that beautiful smile on her face that he loved so much ever since he could remember.

"Will you come over later?" he asked in a husky voice. She didn't really have a choice on this matter, but he wanted her to feel like it nonetheless. For now at least.

A smirk played around her lips. "You know, if it wouldn't be you but Snot who asked that, I'd break your arm now." Hiccup's eyes went wide in mock fear and she chuckled. "But since I know you won't try to get me drunk and into bed, I'd say you're safe."

Now it was on Hiccup to smirk. "Are you sure about that?" he asked teasingly. It made her laugh for real. "I wanted to invite you to have dinner with me, to talk, and maybe…" he trailed off and let his lips brush against hers. "But who knows, maybe I'm going to put drugs in your food to make you compliant. Maybe I'm going to take you by force now that you're mine."

"As if you'd dare to do something like that," she giggled and gave him a playful punch to the shoulder. "Luckily, I know you well enough, Hiccup Haddock. And we both know that you wouldn't stand a chance against me anyway."

She gave him a soft kiss goodbye and then left him standing to enjoy some leisure time. Hiccup followed her with his eyes, the smirk still not leaving his face. Oh, she was so wrong but that didn't change how much he loved her.

Once she was out of sight, he flew to his own hut and took the gifts Stoick had given him off of Toothless back before the dragon retreated to his corner. There were two boxes, one bigger and one smaller one. The bigger one contained various tools, gadgets, and other stuff he'd already inspected back on Berk. It would go up into his sleeping alcove. The smaller box, however… Hiccup opened the top, careful not to spill any of the content. There were nearly two dozen pots and jars in it, containing dried herbs, powders, salves, tinctures, and many more. To the side was a letter, listing all content with explanations of the effects and how to use them. He scanned the list and his lips stretched into a wide grin.

This was perfect.

There was a knock on the door to his hut that made Hiccup perk up his head in anticipation. "Come in," he called, still busy with the frying pan and the two pots on his little stove.

"Mmh, that smells fantastic," Astrid hummed as she walked in. Hiccup was a little disappointed that she hadn't dressed up in anything special for their date, but he hadn't expected her to do that anyway. Not really. That was a topic he would address at a later time.

"I hope you'll enjoy it, too," Hiccup replied as he extinguished the fire and loaded two plates with their dinner. Then he went to greet her with a kiss, more heated than their usual ones but he couldn't help it. She was gorgeous and the past hours of anticipation had done the rest. He wanted her, more than ever.

"Well, hello there," Astrid gasped a little breathlessly as they parted. She looked at him with an expression that was clearly meant to be playfully seductive, peeking up through her lashes and with her lower lip pulled between her teeth. Freia, he wanted to take her right here and now!

It took Hiccup some effort, but eventually, he managed to step back and lead her to the table he'd set for two. He handed her one of the drinks he'd already prepared for them, rose his, and said ceremoniously, "To our future. May it be long and fulfilling."

"To our future," she repeated with a smile that showed exactly what she was thinking. That he was an overly romantic dork and that she loved him for it.

The dinner went as expected. Astrid ate easily twice as much as Hiccup did and washed down the slightly spicy but incredibly tasty food with the light wine her parents had given them. They joked, talked, and bantered for what felt like hours until Astrid started to feel tired.

"I better go back to my hut," she mumbled in a slurred voice, obviously already affected by the alcohol and everything else.

"You could always spend the night here, you know?"

She threw Hiccup something that was supposed to be a glare but held no venom. "Hiccup Haddock. Are you by any chance trying to seduce me? Because that's not working, no. We're betrothed and I know nobody would blink an eye at us having sex now but you won't get me into your bed that easily. No, no, no."

Hiccup watched her with slight concern. She was stumbling as she headed in the direction of the exit. She was clearly intoxicated. He got up and just as he'd expected her next step would have sent her sprawling on the floor had he not caught her.

"Are you sure you're fit to make the way on your own?" he asked, amused. He couldn't really help it, seeing her uncoordinated like this was cute. "I don't want you to fall off the bridges."

He'd expected her to protest further, but instead, she went all mellow and soft in his arms. "Mmh, dunno? Maybe I need a little help after all. You're so warm, do you know that?" Giggling she cuddled her face against his chest and a hand was sliding around his neck. Then she grunted and from one moment to the other went completely slack in his arms.

"Astrid?" he addressed her cautiously. "Astrid, are you awake?" There was no reaction, not even when he called her again, lauder, and even slapped her face. She wouldn't wake up. Hiccup waited a few seconds longer, standing in the middle of his hut with Astrid's unconscious body in his arms - and then a mischievous smirk spread across his face.

That had gone far better than he'd expected! The drops he'd put into her wine had worked far sooner than what the instructions had said, maybe because of how much she drank or because of the alcohol and the aphrodisiacs he'd mixed into their food. Either way, she was now exactly how he wanted her.

Vulnerable.

Helpless.

His.

It took him little effort to carry her up his stairs; the training she'd put him through lately obviously paid off. Toothless didn't so much as blink when he dropped her limp body on his bed. The dragon knew all too well about his master's fantasies. He'd talked about them for years now, after all.

But before Hiccup put his dreams into practice he took a moment to enjoy his victory, the sight in front of him. Astrid Hofferson, Berk's strongest warrior and the most beautiful woman on Midgard laid in his bed. After years of suffering and humiliation, the prize he'd coveted for so long was finally his. And after tonight, nobody would be able to take her from him again.

He took off his stiff leather tunic and the boot and crawled onto the bed until he knelt across her waist. Reverently, he let his hands roam over her body. He enjoyed the slide of skin along her arms and neck but palming her breasts left him a little frustrated. Of course, she'd bound them beneath her shirt, just like she always did. Well, he would break her of that habit soon enough. He wanted to feel her whenever he felt like it.

But for tonight, he'd have to be content with getting rid of her bindings himself, just like the rest of her clothes. He stripped her slowly, one piece after the other, taking off the cuffs for a moment when needed. First her boots, then her spiked skirt and her shoulder pads, then her shirt and leggings. Every bit of revealed skin he covered in kisses, sometimes soft and sometimes hungry. He loved her, adored her, worshiped her. Every spot that made her react, be it a gasp, a moan, or a shiver, he memorized as a sensitive one, one that deserved further explorations on another day. He couldn't wait.

His actions certainly didn't leave her unaffected though. Her mind might have been knocked out entirely by the drugs he'd given her, but that didn't mean that her body wouldn't react to his ministrations, especially not with the aphrodisiacs racing through it. He could feel it too, the heat and the longing in his groin, but he'd hardly eaten as much as she had. The effect had to be so much stronger on her, and really, when his hand glided up her inner thigh it made her moan in an oh-so-lustful way.

But as much as he enjoyed listening to such noises they also made him pause. He trusted in the effect of the drugs Gobber and his father had given him… but he didn't want to risk Astrid waking up at any point and fighting him. So he shuffled off the bed and opened the bigger box he'd bought from Berk. It was filled with many interesting things: gags, and whips, and dildos, and so much more, but for now, all he needed was the leather cuffs right at the top. He secured Astrid's hands to the bed frame above her head and her feet loosely to the posts on either side. That way, he could move her but she wouldn't be able to get away or even fight him.

When he was done, he looked down at her, almost completely naked and bound to his bed. The sight made his breath come faster and his cock swell. Gods, he'd waited so long for this.

He took off his pants and boxers as they grew uncomfortably tight and also shed his shirt and then laid down on top of her. He wanted to feel her. Her skin was hot against his and even unmoving as she was now, she was so alluring to him that he completely forgot himself for a minute. With a groan, he put more weight onto her and ground into her perfect body. His cock slipped between her thighs and even without entering her just yet, it felt fantastic. The heat, the slide, it being her. Hiccup felt everything inside him grow tight and hot as he rutted against her. His eyes fell on her face beneath him. It was soft and relaxed with her lips parted and her breath coming in panting. She was pure perfection. And she was his.

When he came not even a minute later, it was intense. Hiccup pressed his lips to hers to muffle his howl, using her in every way he wanted, and his hand grabbed so hard onto her arm that it was certainly leaving marks. He was looking forward to seeing them on her in the morning. This was so much better than his hand or fucking a whore every now and then, and he knew that it was because it was Astrid beneath him. His Astrid.

Afterward, he took a second to catch his breath again and even giggled a little as he slumped down on top of her. "I'm sorry, my love," he mumbled. "I promise, usually I last longer. But you're so hot and then there are the herbs I mixed into our dinner. They're quite potent, don't you agree? I didn't expect that. You can feel them too, don't you?"

She didn't answer him of course, but she didn't need to either. There were other ways to see whether and how strongly his touch affected her. He was no monster, after all. During all the years his father had taken him to the brothels on other islands, Hiccup had eagerly learned how to please a woman, all to one day put what he'd learned to use on Astrid. She was his end goal, everything he'd ever wanted.

He rolled off her, reluctantly but it had to be, and reached for the knife he kept on his bedside table. With exquisite care, he cut through the layers of her breast bindings and unwrapped her as if she was a gift. Which she was, in a way. She was his gift for having done so well in the past, and now she was his to do with as he pleased. And, oh, the things he wanted…

His breath caught in his throat when the last layer of cloth fell off her and her breasts were free for him to admire. Oh, she was perfect. Pearly white skin stretched over soft mounds, the rosy buds at the top just begging him to pinch and bite them. He'd seen bigger tits than hers, but… he let his hand hover over one perky hill and, yes, hers were just the right size for him to palm them. Perfect, just like everything else about her.

Hiccup took some time to play with her exposed breasts. He was sure that he was the first man to ever see this perfection, let alone touch them. Astrid was chaste and untouched, he'd believed her when she told him so, even though she'd admitted to touch herself every now and then. One day, he would make her do that while he watched her.

But now was not the time to fantasize about that. Now, he dedicated all his attention to her nipples. First, he just brushed over them with his thumb, light as a feather, and even that already made shivers run through her lithe body. She might be unconscious, but that didn't mean that her body couldn't feel. Next, he pinched her and avidly listened to her low gasps before he leaned down to give them some love with his mouth. Feeling those lovely buds harden against his tongue made him get hard again, too.

"It's time, my love," he murmured against her skin. He reached between her legs and beneath her panties and growled when he found her dripping wet for him. Eagerly, he removed that last bit of clothes covering her, taking off the cuffs for a moment when needed, then rolled back on top of her and pushed her legs apart to settle between them. "Time to make you mine!"

He took only a moment to guide himself into place and then pushed into her with one smooth thrust. There was more resistance than he was used to from the whores he'd fucked before; Astrid was so much tighter even with her body entirely relaxed and he even felt when his cock met her maidenhead and tore right through it. There was a whimpering and even something like a low cry from her and Hiccup couldn't resist but to smile down at her and kiss her again. "You can thank me later," he mumbled against her lips. "I've heard the first time is quite painful for a woman. Don't you agree that it's pure kindness that I let you sleep through that pain? You're welcome." Slowly, he pulled out of her again, his eyes lingering on her blood on his throbbing cock, before thrusting right back in. She was his, her body and also her virginity now. He would have to work to make her mind his, too, but the wait would be worth it.

He kept his lips on hers as he fucked her, slow and sensual. This was his moment of victory and he wanted to enjoy it as best he could. And oh did he enjoy it! Coming before hadn't been part of his plan, but now he was glad that it had happened. It meant that he could concentrate on this without the need to rush now. Her heat and the wet slide of her arousal, in and out, watching her tits bounce with every thrust and watching her face twist in pleasure and listening to her soft moans. It was even better than he'd imagined.

When he felt the need in his groin grow and his climax close in he pushed one hand to their joining and searched for her swollen clit. Touching that little bundle of nerves had the desired effect in her already so aroused state. It only took a little rubbing and pinching to make her body shake and spasm with an orgasm and her walls clenching around him was more than he could take.

"Fuck, yes! Aaah-Astrid!" This time, he didn't muffle his shout of ecstasy as he came, buried as deeply inside her as he could and pumping her full of his seeds. It was excellent, all he'd ever dreamed of. Perfect!

When he was spent and done, Hiccup slumped down next to her unconscious body. Chucking, he pulled her into his arms and nuzzled against her neck. "Mmh, that was incredible, my love. Oh, we'll have so much fun together. And we have forever to do so. Because you're mine now. Nobody can take you away from me again."

He bent over her to kiss her again, loving and sweet, before he got up to loosen the chains holding her arms and legs in place - though not releasing her, that was too risky yet. He rolled her around until she lay on her side, then settled behind her, her back snuggly against his chest. "You're mine, Astrid. Finally. And I love you so much."

For a while, he stayed like that, lazily fondled her breasts and enjoyed her soft skin against his own. It didn't take long until his desire stirred again though, the aphrodisiacs still worked through his system, and he adjusted her legs and hips until he could enter her from behind. He couldn't help the low moan when her tight heat welcomed him again. He took her harder this time, his hips snapping forward in search of his pleasure, and enjoyed her low gasps and moans until he released another load into her.

"I wish I could knock you up just yet," he murmured sleepily against her shoulder once he was done, his hand splaying over her lower belly. "But that will have to wait." Because that was the one annoying side effect of the drugs his father had given him. They would prevent her from getting pregnant. But they had all the time in the world now and once she was properly broken in and trained and had accepted his dominance over her, he could stop using them. He was looking very forward to that.

Hiccup fell asleep like that, his soft cock still buried inside Astrid and his arms holding her tight. Every now and then throughout the night, he would wake with his cock burning with renewed desire. Then he would fuck her, quick and satisfying, before he would go back to sleep, idly wondering how she would react in the morning.
