A Dragon’s Lust(+18)

(Another extra long chapter.)

When Jack tossed them on the bed, Kalawarna and Raynare could barely steady their minds. They were no strangers to sex as that was what caused them to Fall in the first place. However, after so many centuries of life, their pride had grown more than their abillities.

They found humans beneath them and now they were being given over to Jack on a platter. Their lie the issue was Jack was very much not human. From the look in his eyes he was a Dragon in Human Form and the Aura that radiated from him seemed to work off the Succubus Curse making them even more aroused. 

That just worked off his great looks, and when his shirt came off, his muscles seemed to pop with strength and power. He climbed onto the bed and he sat himself between them on the headrest.

He wrapped his arms around their hips which caused their already sensitive bodies to surge with pleasure. They gasped as he pulled them up against him like they were weightless.

As much as they hated to say it, this was the best they had felt in years. Jack still managing to keep his sanity spoke to the both of them.

"Before we get down to things, I will explain why this is happening. You see, I am part Dragon and Fallen Angel and I switched out most of my organs with Dragon ones giving me the sexual drive of a one. It doesn't help that I am also part Fallen Angel which are compounding off each other.

I rather not jack myself off every day to satisfy my ever-growing lust. No pun intended, now you two are mine. So, you might as well get used to this. Who knows, you might gain something out of it."

Raynare grit her teeth as she used her hand to push his face away from her. She had no strength and it was more of a last-ditch effort.

"Get off you pervert."

He opened his mouth and he bit her hand hard enough for it to sting, but not hurt. Because of the Succubus curse that came with the Master Servant Pact, she felt her panties flood with love juice at the bit of pain.

"AAHHHH!"

Kalawarna gulped as Jack raised his hand up her womanly body. Eventually, he grabbed her left breast and squeezed it. He let go of Raynare's hand before turning to Kalawarna.

He looked into her yellow eyes with a smirk.

"You have amazing tits."

She twisted in his hold with her face flushing red. He brought his face down and he ran his tongue up her neck making her close her eyes in pleasure. Now, Jack knew why Other Jack didn't kill these two when they came to Kuoh. They were too hot for that and now they were his as well. He grabbed Kalawarna's red jacket and he ripped it off her body.

He did the same for Raynare's black blouse. Since they both didn't wear bras, their breasts were all for his to see. He grabbed both before he hugged them tighter to his bare chest.

"Whoever makes me feel the best will get a reward. The one who doesn't will get punished." He released their breasts and he waited. Both women looked at his face and the way his eyes looked at them. 

It was the same way they looked at humans, he saw them as beneath him. That would normally piss them off, but that was because they were weak. Since they were weaker than him, by his right of strength he could do as he pleased. 

Kalawarna glanced at the bulge in his pants before she made up her choice. It helped that he wasn't ugly and she saw the benefits of cozying up to a Dragon. She began to undo his heavy leather belt.

She pulled down his zipper before reaching into his boxers. When she grabbed his manhood, she almost didn't believe what she was feeling. She pulled it out revealing his 8-inch member. It was still growing, but for his age that was more than enough. He smirked with pride as he could see Kalawarna struggle to contain her lust.

She made her choice as she would show him why it was worth keeping her around. She opened her mouth and she instantly enveloped the head of his cock with her lips. When Jack saw that he grinned as he needed this more than ever.

It would just get worse in the coming months and years so having someone to deal with his desires would make his life less stressful.

"There we go."

[This is so hot.]

'I will get you later.'

As she heard that, Apophis could only remember how last year he barely had any desires. Now, a year later and a few swapped-out organs he was like a different person. Then again, he was just getting older so it made sense. 

[Puberty hit you like a freight train didn't it?]

He ignored Apophis as he placed his hand on the back of Kalawarna's head. She opened her eyes as she heard him talk with almost a bestial growl in the back of his throat.

"Good girl, can you take all of it?"

Rather than stop, she closed her eyes and she forced her head down. She took his entire length into her throat with ease and once she swallowed all of it, she stayed there. 

'Holy shit. I didn't expect that.'

He glanced over at Raynare and saw she was barely holding it together, but he got bored of waiting. He grabbed her by the neck and pulled her toward him. He reached out with his other hand and grabbed her left nipple. He twisted it making Raynare gasp in pleasure and pain.

"Urrgh, don't."

He pulled her face toward him and stuck his tongue in her mouth. There was a reason every body part of a Dragon was valuable as his saliva made her feel energized. He then pulled his tongue out as she looked unfocused. 

"Put your breasts around it. Now."

Seeing how he was demanding she nodded and she crawled up his body before getting ready to do as he said. Kalawarna pulled her head back to let her do that. Once Raynare had the space, her huge breasts went around his cock.

She began to move them up and down so while she was giving him a tit job, Kalawarna stuffed her head between her friend's tits to continue her blowjob. While they were pleasing him, he grabbed Raynare's black panties and ripped them off. He grabbed her ass and he stuck his tongue out.

He leaned forward before he licked her vagina from clit to her slit. He even applied a tiny electric shock to his tongue which zapped Raynare's clit. Just with that, she screamed in orgasm as she splashed his face with love juices. 

"UGGGGGHHH!"

"Whoa there."

While he was distracted, Kalawarna stuffed her head between Raynare's breasts and deep-throated him again. Rather than hold it back, he let himself finish which caused his first orgasm of his life. As he came in Kalawarna's throat her eyes rolled up as she orgasmed as well.

She refused to share as the sheer amount of energy in his semen was too delicious. Of course, that meant she had submitted and she had reached the basic level of the Master-Servant Pact.

As for Jack, he almost went berserk with his first ejaculation. His eyes narrowed more than ever and the sheer flood of hormones in his body almost made him lose his self-control.

He grit his teeth which sharpened into fangs. He began to growl which made Raynare look behind her with hearts in her eyes. Just like Kalawarna, the Master-Servant Pact had been fully engrained making them his.

Around their necks, their bright blue collars proudly settled down. No words were needed as Kalawarna pulled her mouth off his cock. She took every drop, but now Raynare didn't resist anymore. She licked his cock from the base to the head before she took the head in her mouth.

While she did that Kalawarna pulled down her purple panties and her short red mini skirt. Once she was naked, she played with her breasts as he watched. She could see how more black and blue scales were popping around his neck and face. 

He then spoke again to renew their efforts.

"I wonder who will get that reward."

She smiled as she began to join Raynare in pleasing him. She sucked on his balls while Raynare blew him.

'This is how kings feel isn't it?'

[Solomon maybe.]

'You are a pervert, Apophis.'

[Most dragons are.]

He sat up and placed his hands on the two Fallen women's heads. They began to take turns blowing him and sucking on him. He was enjoying this more than he thought he would and he felt Azazel was a true friend. As he came again, he covered their breasts and faces white.

Once again, his hormones overflowed so he lost his patience. He pulled off his pants and threw them to the side.

He grabbed Kalawarna by her ankle and he pulled them toward him.

"Alright, lay flat on your back, spread your legs as wide as you can. I am going to fuck you now. Raynare, masturbate to the side. I want you wet."

They both nodded as they obeyed his orders. Kalawarna got on her back, she spread her legs as wide as she could exposing her pussy to him. She was well-groomed and only had a bit of blue hair. She was wet and from the look of it excited.

"Finally, my prize."

He got on top of her, grabbed her by her legs and since she was wet enough he knew he could go all out. He placed the tip of his cock at the entrance of her vagina before he pushed in with one deep stroke. 

When the tip of his cock hit her womb, he smirked in pleasure. Not only was she soaking wet, she squeezed down on him like a vice. He would only be able to satisfy himself with Supernatural women as mortals could not please him.

"Damn, you're tight. And wet."

Kalawarna raised her head and saw how he was inside her. She hasn't been with a man in almost a decade. Then again, she had never done it with a Dragon before and it was just as good as promised.

Jack strengthened his hold on her sexy long legs before pulling back and slamming back in. She screamed in pleasure as he began to rut her like a mindless beast. Raynare fingered herself as she watched her friend get railed by a Dragon. As he ordered she had to masturbate for his amusement.

When she looked at his face, she saw pure pleasure. While this was his first time, he knew exactly what he was doing and it felt better than he could imagine. He wrapped her legs around his waist, lowered his upper body and he began to suck on Kalawarna's right breast.

She wrapped her arms around his back, and using that hold he lifted her into the air by her ass. He thrust up into her and he pulled her down on him using her like a living fuck toy.

"AHH, ARGH, TAKE IT!"

He squeezed down on her ass and when he felt her orgasm again and scream, he knew it was time.

"I'M COMING!"

He slapped her ass as he pulled her down on him. On the last thrust, he came inside her releasing stream after stream of potent hot semen into her womb. As he did so, he used the contraceptive spell Other Jack made which meant he could cum all he wanted without risking a pregnancy.

However, as he came inside the blue-haired Fallen, the potent Mana and Ki in his semen surged through her body. It caused her womb to feel like it was on fire. It also made her pass out which disappointed him.

"Fuck."

He pulled out of her before placing her on the bed. He looked at her face which seemed pleased and happy. He turned his head and saw how Raynare had stuck several of her fingers in her pussy. 

Her face was flushed and she hadn't stopped. 

"Raynare, show me your ass. You better not pass out too."

"Yes, Daddy."

She turned around and exploded her perky white ass on him. He grabbed her hips and aligned his cock still covered in semen and love juices before he slammed himself into her.

"AHHHHHHHHHH!"

She came instantly, but much like Kalawarna, he began to rut her like he wanted to breed her. He removed his hands from her hips and he grabbed her breasts. He began to pinch and pull on her nipples as he continued fucking Raynare like he did her friend.

"TIGHTEN YOUR CUNT!"

"YES DADDY!"

He smirked as this was something Other Jack had figured out. Raynare was really into kinky sex once her pride was out of the way. She loved being forced and yelled at. As his hips continued hitting her ass, it jiggled and bounced egging him on. Eventually, Raynare couldn't even hear him as she went limp in his hold.

When she had her 7th orgasm he came for the fourth time inside of her. As his semen entered her womb, she screamed as she also felt the same effect as Kalawarna. Though much like her friend she passed out at the surge of power. Jack sighed as he pulled out of her, turned her around, and shoved his cock in her mouth.

He thrust into her throat a few times cleaning himself off before pulling out to not choke her.

"We got to train your endurance. Both of you."

[They aren't me, big guy. How did your first sexual experience feel?]

"It was great, just wish it lasted longer. I got more in the tank."

[Too bad I got no real body. I would help you with that.]

"Thanks. I guess I should clean up."

He left the two Fallen Angels in their sex-broken state before getting into the shower. He took a long hot shower feeling at the top of the world. After about 20 minutes Raynare and Kalawarna woke up around the same time. At first, they were kind of dizzy as if they were drunk.

After a few moments, when they felt the semen spill out of them they realized they were not dreaming. Raynare sighed as she touched her face.

"Kalawarna, what just happened?"

Still naked Kalawarna crossed her arms under her breasts. She sat down on the bed as she stated the obvious.

"We got ravaged by a dragon is what happened. A young one from what I can tell."

Raynare groaned, but as she looked at her pussy, she couldn't help but admit she wanted more.

"That was the best sex ever. Dragons are the best."

Kalawarna nodded.

"It was. He is showering right now. I bet he wants to go another round."

Raynare didn't say anything as the two of them walked toward the bathroom. When they went inside, the sound of two women getting fucked was heard soon after. Jack was still rearing to go as mixing puberty with Draconic urges meant he could go again and again.

Especially when the women were as sensual and sexy as Raynare and Kalawarna.

---

A few hours after Jack finally felt satisfied he left the hotel with his two new servants. He regrouped in Azazel's office on the couch with the two women sitting on his lap. 

They seemed even sexier than ever and their skin seemed far healthier than before. His arms were firmly on their midsections which made Azazel laugh as he looked at the two women.

"What did I say? It was a punishment, but a reward at the same time right?"

Raynare and Kalawarna knew what he meant as being given to a Dragon wasn't terrible. Jack on the other hand gave Azazel a big thumbs up.

"Azazel, you are a true friend. Thanks for that, I feel much better."

Azazel returned the gesture with a grin.

"That is what friends are for. Now then, if you want to go to Asgard, you can go at any time. Odin will second someone to pick you up when you want. You can stay as long as you want and leave when you want.

They just want to learn more about your sword and in exchange, they will train you. All I got to give Odin is a tour through the strip clubs and titty bars of Japan like Old Times." 

As Azazel began to reminisce of his younger days of hanging out with Odin Amara jumped off his desk before running toward Jack. She lept onto Raynare's lap, then on her shoulder before getting to his shoulder where she belonged. 

"Hey girl, missed me?"

"Meow." 

She rubbed her face on his head making him smile. 

"Azazel, call them. I will go first and then I will ask if I can bring some friends. I could bring Vali with me for a time since that kid needs the training." 

Azazel felt that was fair. 

"True, I will give them the call. You can hang out until they arrive." 

He patted Raynare and Kalawarna on the stomachs to get them to get off. When they got off his legs, he stood up and he stretched out. Meanwhile, Azazel called Odin personally and the two got talking. 

Jack waited for the talk to finish which only took around five minutes after the two pervy men stopped talking about what race was the hottest. Once the call was done, Azazel turned to him. 

"Your escort will be here in five minutes. Odin said they are sending a hottie." 

Jack nodded. 

"Cool, while I still got you here, place your bets early. How tall do you think I will be?" 

Azazel thought about it as Jack was 11 at the moment yet he was already 6'1. His Dad was 6'8, and Jack had swapped out his major organs and Glands with Dragon Organs. 

"7'2, or 7'3." 

Jack grinned as he liked the sound of that. 

"Nice." 

He sat back on the couch before turning to Raynare and Kalawarna. 

"We are going to Asgard now for a couple of months. I will be spending a large amount of time there, and while we are in Asgard, I will need you two to join in the training. Just the two of you won't be able to satisfy me if you remain weak. 

Got it?" 

Raynare and Kalawarna knew he wasn't asking. Then again, he was their Master now. Kalawarna instantly agreed. 

"Alright, if that is what you want." 

Raynare followed suit. 

"I understand." 

He nodded. 

"Good." 

After a few more minutes his escort arrived in Azazel's Office. A Norse Magic Circle opened up on the floor and out stepped Brynhildr herself. She was dressed in the combat outfit of the Valkyries, but Azazel took note of something. 

"Three people with blue hair in the same room. What are the chances?" 

Brynhildr shook her head as she looked at Azazel. 

"Azazel, keep your jokes to yourself. You are not funny." 

"Odin thinks I am funny." 

Brynhildr wanted to groan as Azazel was always annoying. She ignored him and turned to look at Jack. 

"Are you Jack?" 

He nodded. 

"Yes, I am. I suspect you are the current Brynhildr yes?" 

She placed a hand over her heart before nodding. 

"I am. My birth name was Vera, daughter of Hodr. Odin is my grandfather." 

She was a beautiful woman and her baby blue hair stood out against his and Kalawarna's dark blue hair. Only his was darker and he had black strands mixed in it. 

"Pleasure is all mine. I got nothing left to do, so we can leave at any time." 

She nodded as she held her hand out and opened up a shimmering portal out of the Bifrost. 

"In that case, come through." 

She stepped through the portal, so Jack turned to Azazel. 

"See you in a few days. I will visit from time to time." 

Azazel nodded. 

"Got it." 

He and Amara stepped through followed by Raynare and Amara. When Jack stepped through the portal he didn't know what to expect, but when he appeared in Asgard, he was instantly in awe. 

The City of Asgard seemed to tower into the sky with marble, and gold buildings. Brynhildr turned around with a smile as she could see him impressed. 

"Welcome to Asgard." 

"It is quite stunning." 

He heard a chuckle so he turned his head. Heimdall had long blonde hair, golden teeth, and white almost porcelain skin. 

"I can tell you want to take the gold for yourself Dragon boy. No shame in it, but looking at the same thing day after day gets boring you know." 

"I can understand that."

Heimdall put his focus back on his watch as this was his duty. Just as Brynhildr was going to lead him into Asgard, Odin arrived to greet him with his sons. 

"There he is, and no longer a virgin. Women are a blessing are they not?" 

Jack grinned. 

"They are, thank you for having me, Lord Odin." 

Odin ran a hand down his beard. 

"Azazel is your friend and that brat is my friend. Plus, I want to see what you can do. Someone hear has been itching to meet you." 

Baldur stepped forward with a huge grin on his face. 

"I am Baldur and I have been itching to meet you. Want to fight?" 

Jack wasn't one to turn down a brawl. 

"Sure, that is why I cam here. Hand to Hand?" 

Baldur already felt he found a friend. 

"Of course. Weapons are good and all, but no better challenge than two men beating the shit out of each other." 

Thor turned to Jack and gave him a short greeting. 

"Enjoy your time. If you ever want to challenge me, come find me." 

He blasted off in a burst of lightning leaving just Vidar, Baldur, and Odin. Brynhildr or Vera bowed to Odin. 

"All Father, I will return to my duties." 

He waved her goodbye. 

"Have fun. As for you two, get to the arena if you want to fight. I have had enough of you boys destroying my city." 

Baldur understood as he, Thor, and Vidar had fought since they were children to see who was the strongest. That title went to Thor, but Baldur wasn't a slouch either. Jack turned to the two of them before waving his hand to get them to walk closer. 

"Alright then. Let's get to the arena. I want to see how I measure up to a God." 

Odin tapped his walking stick on the ground and teleported them to a massive open field. All around them, Vikings were locked in combat. Most of these were the mortal worshipers of the Norse, some were Demigods, or even the children of Demigods. 

Norse Gods liked to Party and had almost as many kids as the Greeks. They just didn't treat them like crap. Baldur took a deep breath before yelling at the top of his lungs. 

"CLEAR OUT!" 

Instantly, every single fight ended and they dispersed. When Baldur came for a fight, no one would refuse him, but they always got pummeled. Once the field was clear, Amara jumped off his shoulder and lept onto Kalawarna. 

The blue-haired Fallen held the cat as Jack grabbed his shirt and ripped it off. Baldur was already shirtless exposing his muscular body. He grinned as he saw that Jack got into a fighting stance.

"Well then, let's get to beating the shit out of each other." 

Baldur chuckled as he stepped forward. 

"Let's see how strong you are." 

He blasted toward Jack who rushed forward before throwing a punch with all his strength unenhanced toward Baldur's face. The god didn't even block as Jack's fist struck his chin. 

In that same moment, he hit Jack in the solar plexus with his extended fist. Baldur's blessing made him hard to harm, but it still let him feel all the pain. Life wouldn't be worth it without that and now, he found his new fighting partner. 

(The funny thing is that Brynhildr and her sisters are all bitter at Rossweisse in the Light Novel because they have no love life. They were jealous of her and Issei in the Azazel Cup.)
