Crazy trouble with love

Female Toothless and Hiccup

Series: How to Train Your Dragon

xxxxxxxxxxxx

-Berk-

We find ourselves following a cloaked figure with two horns on its head as it walked towards the house of Stoic before jumping up and quietly landing on the roof and looked into the window. Only to see a Nightfury and a human boy sleeping in their respective spots.

'Aw, they look so peaceful.' the figure thought with a laugh. The figure when took out a bag covered in runes and opened it while spreading the contents a lover the dragon. 'Hope you love my prank Hiccup because Loki, God of mischief gives my regards.' He chuckled before disappearing in the form of a small ball of shadows.

Inside the sleeping form of Toothless growled and seemed to sleepwalk closer to the bed and climbed onto it before laying down next to Hiccup. "Gre...Hic..cup.."

-next morning-

"COCK A DOO-" yelled a Rooster before getting eaten by a Zippleback as Hiccup groaned.

"Mmm." he grumbled sitting up and rubbing his eyes.

"Hic...cup…" Moaned a voice next to him. "More….fish…"

'What the…' he blinked and turned before his eyes widened and his jaw dropped. It was a human with Nightfury traits, such as a long tail, two small wings, a few pointed scales above the ears and two claw like hands. Oh and it was a naked girl as well, large valkyrie sized breasts and all!

She grumbled in her sleep while Hiccup was utterly speechless. 'What in Odin's name is happening?!'

"Hiccup….more….fish…" The girl grumbled in her sleep while Hiccup saw something strange on the tail, a cloth like fin with a familiar symbol.

'Why is she wearing that? And how does she know me? I've never seen her before.'

Just then she started to wake up and rubbed her eyes with her hands. "Mmmm….Hiccup? Where's the fish?" She then started to look around the room. "Why is the room so small? It wasn't like this when we got back from throwing Snotlout into the sea while putting a fish in his mouth."

"Uh, question. Who are you, and why are you naked in my bed?"

"Ok that's rude I'm always naked. And you don't recognize your dragon?" She said annoyed. "By all that's not eels, if I wasn't your dragon, Toothless, then who else would I be? A White Death?" She then started looking at Hiccup's face. "Did you get hit too hard from that tail swipe yesterday?"

"T-Toothless?" he gasped. "But….that's not possible."

"What's not?" She asked confused.

"Uh, you're kind of…..a girl."

"What?" She said before looking down and instinctively groped her huge breasts. Well...before screaming. "AAAAAAHHHHHH!"

Hiccup reeled back from the volume while loud footsteps ran up and his dad kicked the door open.

"WHAT-" he yelled before seeing Toothless running around like a mad man, screaming like crazy. "Hiccup. Who is this woman?"

"I don't know. She said she's Toothless, but that makes no sense. I think she might be a human/dragon hybrid."

"AAHH!" Toothless screamed while blasts of purple energy blasts started being fring from her mouth at various objects. "I'M A GIRL! BY THE GREAT DRAGON NIDHOGG! HOW IS THIS POSSIBLE?!"

"Now calm down there lass." spoke Stoick stepping in front of her.

"How can I calm down!" She yelled. "I'm a girl! A human dragon girl!"

"Well I think you might need to focus on...something else." spoke the chief looking away.

"What do you mean?" She said cupping her huge breasts.

"He means clothes." spoke up Hiccup while looking away.

"Clothes?" She asked a little confused. "Oh. You mean those things you wear like a snake's skin?"

"Yeah."

"...can't I just go out like this?" She asked with a small grin. "It might make someone faint like Snotlout."

"Just borrow some of my clothes." spoke Hiccup.

"...but it's too small." Toothless said while pointing to her chest. "Especially with these."

"Just put something on." spoke Stoick leaving his son and the girl alone.

"Hiccup." She said with a smile. "If I am going to get dressed, then can you help me?"

"W-Why?"

"Because I trust you." She smiled while hugging him close to her breasts. "A lot."

'Sweet Odin they're so big!' he thought with a bright red face.

"Hiccup?" Toothless asked. "Are you ok with a Dragowoman?"

"Uh, is that what you're calling yourself now?"

"No. I call myself Toothless the cute." She grinned.

"I meant your….appearance." he got out while trying not to move against her chest.

"Oh. Well maybe." She blushed. "Are you sure I need clothes?"

"Yes." Hiccup blushed. "Especially if you want to keep others from either fainting or looking at you like...a piece of meat." 'Damn it, these are so huge!'

"Oh fine." she sighed letting him go as he got off the bed and walked over to his dresser.

-later, in the village-

"Ok." Toothless said annoyed as she was wearing a few of Hiccup's clothes with a helmet covering her head, gauntlets covering her claws and a long cloak covering her wings and tail. "I feel a little constructed. Are you sure I can't just go and get myself out of these annoying clothings?"

"Considering no one else knows what happened, we don't even know what happened. I'd say it's a good idea if we just keep it on the down low."

Toothless sighed. "Fine but if anyone starts poking my face I'm going to blast them, Hel be damned." She then noticed Astrid walking up and waved. "Hey."

"Uh, hey." greeted Astrid confused by the girl. "Uh, are you new to the village?"

"No. I have been here for years." She said while Hiccup panicked. "So how's your dragon, Stormfly?"

"Good, why do you ask?" Astrid raised an eyebrow.

"Well. She owes me some fish." She said annoyed. "Last time I eat an eel because of a dare."

Hiccup tried getting Toothless to stop while Astrid put a hand on her hip. "Why do you say she owes you fish?"

"Because she came up to me and asked me to blast Snotlout in the ass. I agreed and I'm still waiting." She growled before calming down. "So how's your day?"

"Uh, fine. Hiccup, can I talk to you?"

"Sure?" He said before being grabbed by the arm and found himself being dragged to a dark alley.

"Hiccup, who is she? She acts like we're friends, but I've never even seen her. And all that stuff about my dragon owing her fish? Is she…..a special case?"

"Um...you're not going to believe me if I tell you." He said while nervous of her berserker temper occurring.

"Try me."

Hiccup sighed and braced for the outburst. "That's Toothless."

Astrid looked at him like he was crazy. "Did you hit your head?"

"No." He deadpanned. "It's the truth for Odin's sake."

"I find that hard to believe."

Hiccup sighed before turning to the girl. "Toothless can you come here a second?"

"What is it?" asked the Dragowoman.

"Can you show Astrid you're right claw?" He asked while said girl looked confused.

"Finally." grinned Toothless before pulling the gauntlet off. Which cause Astrid to look at her in shock. "What's wrong Astrid?"

"Y-Y-Your hand."

"Is a claw." Hiccup said. "This IS Toothless and I don't know how in the nine realms this happened."

Astrid was blown away while Toothless took the other gauntlet off with a sigh.

"Can I undress now?" Toothless asked while taking off her helmet.

"No." spoke Hiccup in a firm tone.

"Aw." She pouted. "But can I please get these," she pointed to her chest. "Out, it's making it difficult to breath right."

"Wait, if you're really Toothless, then why are you girl?"

"No idea." She said while unhooking the front of her clothes, and releasing the large breasts. "AH! Much better."

Astrid's eyes widened in shock. 'Woah.'

"What?" She asked. "Are you….jealous?"

"Toothless!" spoke Hiccup in fear for Astrid losing it.

"What? It's a little true when I was a dragon. I was really jealous of Astrid's chest." Toothless said with a light blush.

"Wait what?" spoke Astrid in surprise.

"It's true. Heck when you rode on my back the first time. I was extremely jealous so...I just decided to give you a 'bumpy' ride."

"...you were still male when that happened, right?"

"What, no, I was female. The last female." She said proudly.

"Uh, Toothless? Before, I saw that….you were a guy." spoke Hiccup while coughing into his hand.

"What? Must be your imagination." Toothless said before hugging both Vikings. "I love you guys, you're the best friends I ever had."

"No problem." spoke Astrid patting her back. While still finding this completely awkward.

"So." Toothless grinned. "Want to get some fish? I'm hungry."

"Sure." spoke Hiccup.

"Great." She grinned. "But no eels. That stuff is disgusting!"

"We know."

-grand hall-

Both Hiccup and Astrid were shocked as Toothless devoured fifty fish in just over an hour.

"Mmm, that hit the spot." she sighed while patting her stomach. "Can I have seconds?"

"You're still hungry?" spoke Astrid with surprise.

"Yes. And," she grinned while picking her teeth with a fork. "I'm hungry for another fifty plates of fish too."

"She might eat us out of fish." whispered Astrid.

"At least it's not sheep and yaks." Hiccup whispered back. "Otherwise we might go hungry for a while."

"Hey Hiccup." Toothless asked while eating a large fish tail. "Can I also have a sheep? I heard they are delicious."

"Maybe just stick with the fish."

"Fine." She said while finishing the last of the fish. "AH. So good, did you want some Hiccup?" She was about to attempt to cough up the fish like before but found it didn't work. Instead it caused her to feel sick. "Ugh...that didn't feel good…"

"Considering you're half human now, looks like you can't do some of the things you before." theorized Hiccup.

"So I can't fly anymore." She pouted. "Or even retract my teeth?"

"Have you tried either?" asked Astrid.

Toothless nodded no before trying to retract her teeth….which didn't do anything at all. "Damn it to Hel!" She then tried to fly but...nothing happened at all. "DAMN IT!"

"Looks like you're more human than dragon now."

Toothless growled before blasting Snotlout in the ass, who cried out in pain. "Much better."

"Hey! Who the Hel…" he stopped while turning around and was stunned at the girl sitting there.

"Turn around or I will break off your legs and feed them to you." Toothless growled.

"I'd listen to her." spoke up Hiccup who didn't like his cousin, but he didn't want him to find out who the girl was.

"Oh?" He laughed before walking towards Toothless. "Well maybe I should get to know her better."

"Bad idea." Astrid shook her head.

"So what's your name baby?" Snotlout said with a smile.

"...Toothless." She growled. "And you're dead meat if you even touch me you meat headed troll."

Snotlout blinked as she stood up and saw she was taller than him.

"And if you ever talk to me ever," she removed her helmet, gauntlets and robes to reveal her full dragon features. "I WILL KILL YOU AND SEND YOU TO HEL!"

"AAAAAAAHHHHH!" screamed Snotlout in a high pitch tone before running from the hall.

"Sorry. But he was an asshole." Toothless said calming down and sitting back at her seat. "So….anymore fish?"

"Toothless! I don't want you to just go off and reveal yourself. People are fine with dragons, but how do we explain you suddenly becoming part human and a girl?"

Toothless looked down. "I...I don't know. But maybe they will accept me?"

Just then a small bundle of animal skins appeared out of nowhere and landed on the table.

"Huh?" He said before opening the bundle and saw...a carving of Loki with a note reading, 'Like my prank? Well it's permanent! HA HA!'

"Loki." growled Hiccup. He then noticed another part of the message. 'Also it's...DRAGON MATING SEASON!'

"So Loki did this?" asked Astrid.

"Apparently." Hiccup groaned. "And it's dragon mating season too….by Odin this isn't good."

"Why? I feel just fine." shrugged Toothless.

"Are you sure?" Hiccup asked. "Because you are hugging me too tightly!"

She blinked and saw she somehow moved over to Hiccup and engulfed him in a hug. "Ok. This is nice." She smiled while nuzzling his cheek. "Hiccup~"

"Uh, Astrid? A little help?"

Astrid smiled. "Maybe, maybe not."

"Please"! He called out as Toothless squeezed him tighter.

"Only if you let me hug you next." She chuckled.

"Uh, alright?" he replied in confusion.

Astrid then hugged Hiccup. "Much better. Now Toothless, can you get off him?"

What she got was a growl from the woman before she swung her tail and knocked Astrid back.

"HEY!" Astrid yelled. "What was that for?!"

"MINE!" growled Toothless with her eyes became slits and hugged Hiccup closer to her chest.

"I get it." Astrid sighed. "But," she grabbed an ax. "THAT DOESN'T MEAN YOU HAVE TO TAIL SLAP ME!"

"Uh, Astrid? I don't think she's listening." spoke Hiccup in nervous seeing the woman bare her teeth and claws.

-one cat fight later-

"Ow." Both girls groaned while still in a fighting stance, in a now damaged hall. "You're good."

"Um, we good now?" asked Hiccup looking up from behind one of the tables he used as a shield.

"Yes." Astrid said throwing the ax at the wall. "But next time you get angry from a simple hug, I will defeat you."

"Bring it."

Both girl butted heads again as Hiccup decided intervened and got in the way of them.

"Look, let's just calm down." he suggested only to accidentally grope Toothless' breasts. 'Oh crap!'

Toothless grinned before hugging him tight. "Aw Hiccup~ You're so bold."

"Ah!" he groaned from having her smush his head against her breasts again.

Toothless smiled before doing something unexpected. She kissed his lips.

His and Astrid's eyes widened with said male unable to pull back from her grip. Good thing the halls were empty due to the fight or this would have been more awkward.

'I can't believe she's kissing me!'

Toothless broke the kiss and said in a low tone "Mate with me~"

"W-What!"

She said it a little louder. "Mate with me."

"Woah there." spoke Astrid. "You need to take a deep breath and try to keep your head together."

Toothless took a deep breath and yelled. "MATE WITH ME HICCUP!"

"M-M-Maybe just hugging is good enough." he chuckled nervously.

This got Toothless pissed. "I WANT TO MATE WITH YOU AND I WILL NOT BE DENIED!" She then started to tackle him to the ground and started to rip Hiccup's clothes only to stop, as she just realized what she was doing and started to shake. "N-No...I can't do this to Hiccup! I-I just can't!"

Hiccup ignored his nude nature as Toothless backed up in fear.

"I-I can't...I'm not…" She said while balling up and sniffling. "I'm a monster…"

"No you're not." Hiccup said sternly. "You're just a little aggressive, but you're not a monster."

"YES I AM!" she yelled out before balling into her arms. "I-I-I'M SCUM!"

Hiccup walked over and hugged her. "No you're Toothless the cute and my dragon. Just stop beating yourself up, for me?"

"But I tried to force you!" she cried out with tears.

"But you stopped yourself." Hiccup said while wiping away the tears. "That shows you're not a monster, but a cute girl that needs a hug." He then hugged tighter against Toothless' body.

She sniffled and shyly returned it.

"Now." Hiccup blushed. "If you want to...mate with me it's fine but," he looked at the Dragowoman sternly. "Tell me why you choose me?"

"Well, you tried to befriend me even though all vikings use to hate dragons. That's pretty bold when I could have killed you when we first met."

"Well. You were being commanded by a larger dragon so it wasn't your fault to act like a vicious Nightfury." Hiccup said while looking away.

"Plus when I got hurt, you went out of your way to help me fly again when you could have just let me stay like that."

"Well I just thought it was the right thing to do." He admitted. "Even if you were pissed at me the last few times I tried to help earn your trust."

"And you made a huge change to viking's history. If you didn't learn to befriend dragons, I'd still be fighting against them and it would never end."

"Or worse. Getting eaten by that overgrown dragon." Hiccup chuckled grimly. "But hey that's the past, and now is the future."

"Well those are my reasons for you, but I knew it wouldn't work." she looked away.

"Why is that?" He asked.

"I was male and I doubt you'd be eager to mate with me." she frowned.

"Well Gobber is gay and you don't see me running away."

"So...if I told you before….you'd accept me?"

"Yes. Even if I couldn't understand dragonise." Hiccup said while a light blush.

"HICCUP!" she tackled him and started kissing all over his face.

"Gah." He gasped before laughing. "All right. All right. Just calm down with the kissing."

"No."

"Well." Hiccup sighed. "I guess I won't be able to mate with you then if you keep kissing me."

"But why?" she pouted.

"Because I doubt kissing helps with..um would you lay eggs or give live birth?" Hiccup asked confused and red faced.

"Let's find out~" she purred before reaching down and trailing her claws across his dick.

"AH." He moaned a little as Toothless started to rub his cock up and down. "T-Toothless."

"Just relax and let me do all the work." she growled out while licking his ear and felt his cock slowly standing up.

"Toothless." He moaned as she started to rub faster as Toothless started to moved closer to his face and lick his ear.

"Uh, I'll leave you two alone." muttered Astrid with a blush as she left the hall. 'Even if it was getting to the good part.'

Toothless smiled before deciding to move back and start licking the tip of Hiccup's cock. 'So big~'

"Toothless." Hiccup moaned. "You're so beautiful."

Hearing that made her smile while dragging her tongue all across the sides and tips of his cock.

"Um…." Hiccup said while looking at her huge breasts with a massive blush. "Can I...you know?"

"Rub your cock in between my chest?"

"No." He blushed. "Um...suck on...them?" 'So embarrassing!'

"Oh, sure." she smiled before moving up with her breasts in his face.

Hiccup blushed as he started to suck on Toothless' right breast. Which caused her to instinctively moan loudly.

"Mmm, I had no idea having breasts was like this." she smiled hugging him closer against her mound.

Hiccup continued to suck as his cock started getting bigger in Toothless' claws, as well as making said Dragowoman's tail wag with happiness.

'I wouldn't mind keeping these.' she thought with a lustful growl.

"Toothless?" Asked the boy while momentarily stopping. "I think I'm about to-"

"Ejaculate?"

"Yea, more like cum." He said before releasing his sperm all over Toothless' claws along with hitting her breasts and a little of her face in the process. He took a moment to pant as Toothless held the claw up near her face.

"Yum." She smiled while licking her claw. "Looks like Hiccup is well endowed~"

He blushed before feeling her tail softly rub against his cock.

"So." She grinned. "Like my tail? It's soft, scaley and the perfect way to arouse you~"

"Y-Yeah." he nodded with a groan.

Toothless smiled before asking a life changing question. "Want to have one child or a nest full?"

"C-C-Child?" he spoke in surprise.

"That's what I want, your child or children if you want." She growled lightly.

"W-Well, I'm not sure. I never really thought about how many kids I'd want."

"So." Toothless asked. "I guess nineteen is too much then?"

"NINETEEN!?" he exclaimed with wide eyes.

"Well dragons do lay lots of eggs so since I'm half dragon now," she smiled lustfully. "I thought maybe having lots of children might be a joyful one~"

He blushed as she moved over him and rubbed her folds against the tip of his dick.

"Yep." She moaned as she started to slowly push her folds into the cock's tip. "It's going to AAHH!" She cried out as her folds engulfed the cock as some….greenish red blood came pouring out of her. "IT HURTS!"

Hiccup groaned feeling her tighten up and tried rubbing her sides at seeing tears in her eyes.

Toothless moaned lightly. "T-Thank you Hiccup." she tried breathing in and out to ignore the pain.

"Toothless." He asked concerned. "Are you sure you want to go on?" 'Not that I mind but I don't want to hurt you...again.'

"Just give me a moment."

"Well. Ok." He said while moving his hand to touch Toothless' claw. "I won't rush you."

She smiled and licked his cheek while slowly feeling the pain go away.

"Um Toothless?" He asked. "Are you sure you ACTUALLY want nineteen children?"

"Hmm, you're right. Thirty sounds more fulfilling." she smiled.

"WHAT!" Hiccup yelled while turning pale, only to see the now laughing Dragowoman. "Oh ha ha, real funny."

She winked before slowly pulling her hips up before slamming them back down onto his cock.

Hiccup moaned as Toothless' hips started slamming down on his cock, which he found erotic to say the least as both her breasts and hips with bouncing in succession and making him have a slight nosebleed. It also didn't help her tight hole was squeezing his cock with each bounce. "You're so tight!"

"Of course, it's my first time after all." She moaned as she moved her hips up and down his cock. "Plus my body is only for you Hiccup~"

He grunted and reached up before grasping her large breasts.

"Mmmm~ If you wanted to grab my chest, make sure to do it well, Hiccup~" Toothless said seductively as her folds started tightening over his cock. "Give me more!"

Hiccup nodded before groping her breasts, hard while Toothless let out a moan of pure pleasure from the grope. "Like that?"

"YES!" she moaned rocking her hips up and down harder.

Hiccup grinned as he continued to assault her breasts. 'I still can't believe how huge and soft these are!' Just then he felt his internal instincts swell up and well….burst out like a dam.

"AHHHH!" moaned out Toothless that sounded like a roar feeling Hiccup's sperm shoot up into her folds.

"Ah...ah...wow…" Hiccup panted. "I guess I was more of a viking then I ...realized…"

"Oh yeah." she nodded laying down and resting on top of Hiccup with a smile.

The moment would have been perfect….if Snotlout didn't come running in with Astrid trying to stop him.

"You idiot! It's not a-" she stopped with her and Snotlout staring with wide eyes at the scene. "Good idea."

"...WHAT THE HELL!" Snotlout yelled while also jealous that his cousin got laid before him. He was about to say more only to get knocked out by an ax, courtesy of Astrid.

"Thanks." smiled Toothless.

"Anytime." She grinned. "But you have to do one thing for me."

"I'm not sharing." she frowned.

"Not that." Astrid said annoyed. "I was just wanted to be the godmother of your children."

"Oh, that I can agree to."

"And to….let me keep Hiccup company on occasion." She blushed. "Since he is my younger brother figure and all."

"Fine, but if that becomes anything more…" she let out a growl to finish it off.

"Like what? Giving Hiccup a bath?" She chuckled. "I'm not that desperate to see him anymore naked than today."

"No, I mean I would drop you from the heavens themselves."

Astrid paled. "Alright! No need to go all draconic on me, even if you can't fly." She said while muttering the last part.

Toothless yawned before snuggling on top of Hiccup.

"So." Astrid asked while finding the scene...cute. "What should I tell Stoick?"

"The truth, now let us get some sleep."

Astrid nodded before walking out of the wall, leaving the two, still on the floor, as Hiccup closed his eyes and fell asleep.

(Timeskip)

We find Hiccup looking at the scenery with Toothless sitting on a huge bed of animal fur and metal objects, from Snotlout's home, with a smile on her face.

"I can't believe it. Twenty eggs." spoke Hiccup looking at the nest of eggs with Toothless lying on them.

"Well it would have been better if we had thirty." Joked Toothless while moving a little on the nest. "So...is this perfect for you Hiccup dear?"

"Well it'd be wrong to say no. And since when did you call me dear?" he joked.

"Since now~" she growled lightly while nuzzling Hiccup's cheek. "Now we just need names for all of them."

'Hel!' Hiccup though while the screen turned black.
