Demon King Who Will Rule the Infinite Worlds

Throne Room,

"How is it going," King Aurum rested his elbow on the armrest, holding his head. He was leaning, watching Tifa bow in front of him, wearing her maid uniform. Her cleavage was exposed to him, her creamy flesh was pushing up and her dress had a shorter skirt to give a peek of her stockings and garter belts.

"It has been going well. Lady Eve has reached Early Apprentice Rank, while Young Master Cloud and His Highness Arthur have reached Middle Stages," Tifa reported, and King Aurum's sharp blue eyes stared at her. Her cheeks blushed red. She could feel his gaze, and her heart was beating fast, and her body was hot, and her pussy was wet. Being near the King did that to her.

"Is that all," King Aurum was toying with her, and Tifa could sense that. Her master had given her a warning that the King had a terrible personality and was an asshole to boot, especially to those he deemed interesting and powerful.

"Yes, Your Majesty," Tifa answered. The King looked down at her, and he knew the answer to that question. He could sense it. She was trying her hardest to control herself from fidgeting, and she was nervous, "I am only a step away from Vanguard Rank. All by Your Majesty's grace."

"Come here."

"Y-yes," Tifa approached the King, who looked at her, his sharp blue eyes making her feel as if he was peeling her off, and she was exposed. His fingers grabbed her by her chin, his eyes looking at hers, his gaze making her feel like she was naked in front of him.

"Sit with me."

"Your Majesty?"

"You heard me."

"I..."

"Or I could always order you to."

"N-no. Of course not," Tifa answered quickly.

She was surprised by his strength when he pulled her on his lap. Her body was stiff from the contact and how his hand wrapped around her waist and held her body tight, pressing her against him. She was embarrassed, her face was flushed and her eyes were lowered, her breathing was shallow.

She shifted to adjust herself and calm herself, and the King was silent. His hand was on her thigh, and she felt his finger running down her skin. He looked down at her and she looked away, not being able to meet his gaze. He pointed forward, making her look at the wide throne room. The hall was empty and quiet.

"Does it still feel scary as when you were standing there?"

"What?" She softly whispered.

"My Authority."

"No..." Tifa softly shook her head. She could still feel the same presence of King Aurum. It was as if he was surrounding her from all sides, but it was not as bad as before. It was a pressure, but not one that made her feel like she was about to faint.

"I feel your presence all around me," Tifa admitted. The King looked at her, and she could feel the weight of his gaze. It was like he was looking straight at her. His hand was on her thigh, his finger tracing circles on the inside of her leg. He kissed her forehead, keeping his lips there, "does that scare you?"

"No."

"Do you feel my Power?"

"No...I only feel your presence..."

"Do you like it?"

"It's like a warm blanket," Tifa honestly answered.

"Then why are you so scared?" He kissed down to her temple, his finger going further, making her jump as he caressed the fabric covering her.

"You are the King...Your Majesty," Tifa spoke. King Aurum was a dangerous existence, one that she couldn't fully comprehend or understand, "I can't resist you...with power...or even will..."

"Aurelius."

"Your Majesty?" Tifa tilted her head.

"Aurelius Aurum. That's my name," the King softly spoke, "if you don't understand me. All you have to do is ask."

"Then...why are you doing this? Your Majesty? Calling me alone...knowing what it does to me...teasing me like this?" Tifa's cheeks flushed red as she looked at the King.

Her pupils trembled, her flimsy courage barely keeping her together, and her breath was shaking. Her hands were holding his, keeping them on her thigh.

"I have been thinking about your future, Tifa. Right now you are acting as Augustus's Maid, but that can't remain so forever. Cloud is rapidly gaining strength. Soon, I'll adopt him in the royal family. On top of that, your position is Arthur's Aura Furnace. You possess an Authority Second Only to Royalty," Aurum interlocked his fingers with Tifa's, "My thoughts are a bit jumbled. There's the thought of you and Cloud loving each other."

"Once he becomes a Royal. My Son, and when he marries you in future you'll be my daughter-in-law? That's weird. Keeping that in mind, everything you do now will be important and scrutinised in the future. I need to insulate you for that. It's a good position you being the Maid. For you, for Augustus, and surely for Cloud, Eve and Arthur."

"Yet, it might cause some trouble in the future when it comes to political marriage with the Prince who represents Once Human. You also have great potential in Martial Arts, seeing how you are at the verge of reaching Vanguard. I should have you be taught Techniques that could best bring out your power-!"

Aurum tilted his head, looking at Tifa, her lips attached to his. She pulled her lips away when he didn't kiss her back. She tucked her back hair behind her ear, "you think a lot...don't you?"

"I am The King here," Aurum responded, and she softly kissed him, "mhhmm..."

She stopped again, "I'll be your daughter-in-law?"

"Mmhm. Strange, right?"

"Very," Tifa pursed her lips in a smile. She curiously asked, "I heard...you were young when you adopted Young Prince Arthur..."

"True," the King softly replied.

"Is that weird too?"

"It's not," Aurum shook his head, "A little brother, son? The relationship doesn't matter. I love that kid and I will protect him no matter what. That feeling won't change. You and Cloud are the same Tifa. You are my people now. I will protect you and want what's best for you. Now and Always."

Tifa placed her knees on the throne and his lap. Her legs straddling his thighs, "Your Majesty...what do you want from me?"

"To know you. To see you and not see the fear in your eyes," his blue eyes softened, "to provide you a home, a place where you can feel safe, and a life which you could live for yourself."

"Tifa. What kind of life do you wish to have here? What would you like to do?"

Tifa stroked his shoulder as her dress fell down, revealing her white flesh and red bra. She pressed her lips to his again. She kissed his neck. His eyes narrowed as his head turned, letting her nibble and suck on him. He softly groaned in pleasure when her hand rubbed on the tent on his pants, and her eyes narrowed as his hand circled around her, pulling on the bra strap.

"A home, Your Majesty..." Tifa breathed out in his ears, "a family, with the one I love...I want to train my Martial Arts too. I want to help Arthur...thank him for what he did for Cloud and me. I want to support him and Cloud. I want to visit the village at times, meeting my Mom and Dad once a week. Once a month will do too...and I want to make more friends."

"I can do that for you," Aurum cupped her chin.

Tifa stroked his forearm with both hands, looking into his eyes, "Your Majesty...then will you be my loving family too?"

"Soon, Cloud will be my adopted son, and that means..." the King whispered.

"Yes...I'll be your family too," she teased, "maybe I'll start calling you Daddy?"

"Uh-huh, anything but that please," Aurum scoffed. 

"Daddy...you make me go crazy," Tifa whispered, "Why?" 

She didn't give him the chance to answer, "I am not like this...but the thoughts in my mind right now...I want you to hold me, accept me, love me too. I want to..."

"Feed on very twisted feeling?" Aurum completed her sentence.

Tifa nibbled her lip, looking up, nodding, "Yes...why? I know I am not like that...I don't enjoy that...and I don't want to hurt Cloud..."

Aurum raised his finger in front of her, pointing it at the ceiling. A white pearl formed on the tip of his finger, "this is you," a drop of blue aura entered the pearl, causing it to vibrate, from slow to fast until it started thrashing, always returning to the same spot at the tip of his finger, "this is you when I put my aura in you, and the place where it centres is your love for Cloud."

Tifa nibbled her lip, staring at the blue pearl thrashing. It scared her. She instinctively knew that she'd die if this pearl hit her. It wasn't until King Aurum cupped her cheek that the fear slowly left her and she looked at him.

"I forget how weak you are," he stroked her cheek, "My aura might make you go crazy a little, but this desire to feed is from you becoming a Demon. We feed on such twisted pleasure because this twistedness is our spice. 

The fear didn't stop her for long. She was like that pearl, going insane with the desire for him. 

"Daddy," Tifa kissed his lips, "I like calling you that...it makes me wet," Her tongue slithered out, and he met hers. His hands stroked down to her ass, holding the fabric of her panties. Tifa reached down between their legs, stroking him, making his body tense, his fingers digging in the fabric of her underwear. Tifa felt the bulge under his clothes. It made her pussy throb. Her hand grabbed at the cloth of her skirt. Her breasts were squishing against his body, "Mhmmm..."

The King groaned in the kiss when Tifa slipped her tongue into his mouth and swirled it against his. Tifa kept his lips locked with hers and stroked him, rubbing her palm and her hand over the thick shaft of his cock.

"Mhmm, mm," Tifa softly moaned as she felt the fabric of his clothes brush over his dick, "Ahhn, ahn," her hips rolled against the fabric as the bulge poked and pressed between her thighs, "I'll marry Cloud in the future...you will be my father then..."

"You are sticking to that," Aurum raised his eyebrow. Tifa lowered her head and bit down on her bottom lip when the King held her by her hair and yanked her head backwards, her body pressing on the throne. Her cheeks flushed pink. Her pussy clenched, making her feel hotter. Tifa whimpered, moaning loudly as she pressed his palm to her crotch, "hah..." 

Her voice rose higher, panting loudly. She spread her thighs and looked up, his blue eyes staring into hers. She held her breasts with both hands. She was turned on by him watching her, and she stroked his cock while rubbing his bulge between her legs, and she pulled her panties to the side and touched her fingers to her pussy lips.

"What are you going to do then? Daddy? While your son is gone...will you climb onto your daughter's bed...in her pussy...your big, fat cock?"

"That's going too far," The King smiled at her antics, pulling on her panties. Her voice hitched as her body rose. The thin fabric slipped through the crack of her pussy lips. His thumb traced the fabric of her bra. The fabric covering her boobs.

He stroked her soft skin. He softly flicked and tugged at her nipple. He circled the pink areola, teasing it until the tip was stiff and sensitive, and her tits felt so swollen and heavy that it made her want him even more.

"Can you please play along..." Tifa gasped and her mouth opened, her breasts were soft and firm, "Will you...in my room...fuck me?"

"It's your grave, Tifa Lockhart," Aurum chuckled to himself. He lightly kissed her lip, "Yes, Tifa," Aurum spoke. He lifted his palm, "with your door unlocked. Just like that. So I can take your pretty pink little pussy when your husband is gone."

"Ahn, Daddy..." Tifa stroked herself and she started riding the bulge. She panted, and she felt it rub over her soft skin. She stroked him off while his hands reached between her thighs to pull her panties aside and pull the crotch fabric from between her folds, "what about my wedding night? Will you come watch your son fuck me? Or will you peep through a hole, watch him hammer me?"

"Yes. And if I do. Would you make it good?" the King questioned. His hands wrapped around her breasts, fondling and squeezing her mounds while he stroked and flicked the fabric of her panties between the swollen and throbbing slit. His hand pushed between her legs to rub his fingers over the bare flesh of her pussy lips.

"Will you open your legs and arch your back. Ride his cock, screaming his name and tell him you love him? Knowing I am there?" He growled, his finger pushing into her.

"Anhhh, Yes, Yes!!" Tifa cried, her voice trembling, and she whimpered. The sound of her voice made him thrust his hips up into her hand as his cock pushed up between her thighs. The tip was wet. She stroked his shaft, his pants slipping away from his waist, and she felt it against her hand, thick, hot, throbbing and pulsing with each of her heartbeats, and her panties slipped and rubbed between her cunt lips, soaking wet. The fabric slipped wet from her cunt.

"I will let Cloud fuck me so hard, Daddy..." Tifa breathed, panting. She rolled her body on top of his cock, feeling him between her legs, and the tip rubbed over her clit and over her lips. Her hips rolled forward.

He grabbed her ass, pressing his shaft against her wet slit. She pressed on his chest, raising her ass, feeling his finger enter her pussy from behind. She sweetly whispered, "but once he's done? Are you going to visit me? Daddy?"

"Will you wear your wedding dress again and wait for your Daddy?" he fingered her faster. The fabric was wet, sticking to her pussy.

"Yesssss!!!! Yes!!" she cried out. The pleasure rushed through her, her hands clamped around her tits, her knees squeezing her chest. Tifa's fingers sank into her own breasts and her knees trembled. Her panties were sticking to her flesh. Her body shook as the waves of her climax rippled through her. The juices rushed from between her thighs, her thighs quivering.

Aurum's finger was buried deep in her pussy as her hips bucked. His cock rubbed between her legs. She fell back in his chest, gasping, "I will Daddy...I will be my Daddy's bride on the same night I am my husband's bride..."

"You will climb on my bed and push that fat cock into my tight ass and pound me? Daddy?" She stroked his cock. He groaned, and her eyes stared into his.

"I will, Daddy, I promise I will...you'll come into your room and see me there, with my pussy dripping with Cloud's cum. My cunt sloppy and used, and I will raise my ass, telling Daddy to come to me and give me a real pounding," she teased. She stroked his cock, "look at this monster of a cock. I'll have it in my ass on my wedding night."

"Tifa..." Aurum moaned in pleasure.

"Daddy...you'll pound me so good...you'll push my legs up...bending my ass..." she whimpered and moaned when she stroked the shaft and felt her clit pressed into his cock, the fabric rubbing her lips. Her fingers sank into her breast flesh, and she bit down on her bottom lip, "won't you?"

Aurum didn't answer her, but he reached out for her face and pushed her head towards him, pressing her lips against her in a hot, sloppy and wet kiss.

Her voice hitched in pleasure, "yes...fuck...Daddy..." She could barely move. She pulled on her panties, stretching the fabric tight over her pussy, and she felt his finger pushing between the lips and entering her.

"I'm going to fuck you on that desk..." his hand squeezed her breast, "fuck you against that window..." his hands were holding her hips and ass. Tifa cried as his cock pushed against her, "then on that carpet..." her heart pounded, "is that what you want?"

"I do~! I do, Daddy~!!" she purred. Her ass swerved and pushed against his hips. Tifa felt her heart beating so loud in her chest she could barely breathe. Her breath was trembling, her breasts heaved with her every inhale, "but...will I call you Daddy forever...? How about Father...?"

"You will...that's the whole point of calling you Daughter, Daughter."

"Ahh, I want that..." Tifa's cheeks were pink, and her lips were pursed. The two looked into the other's eyes, her hand was holding his arm while he stroked and pulled on her nipple, her eyes narrowed and she breathed harder, "I am your Daughter, Daddy~ I want your big, thick cock...to fill my ass up with your hot cum, Father..."

She turned and pressed her ass into his hips. Tifa bit down on her bottom lip, stroking the shaft, and the wet fabric rubbed the soft skin. Her pussy throbbed as she rolled her hips and his finger rubbed her swollen and sensitive clit, her panties slipping through her folds, "it'll be a mess."

"A mess in my tight little ass? Fuck~!"

"Tifa..." the King moaned, his voice getting higher. Her hands and arms trembled, and he squeezed and pulled on her nipple harder, his hand pushing on the inside of her breast. She gasped as she felt a warm tip against her puckered hole. Her legs nearly gave out.

"I love that cock so much. That fucking cock~! It feels so good, Father..." Tifa bit her lip as she felt her knees give way and her body bent, "Fuck~ I am going to be fucked so good by Father's big fucking cock."

Her moan turned into a cry and she nearly fell on his chest as his finger curled and thrust into her cunt. Her legs and knees buckled, and he stroked himself off. The top of his cock rubbing against her ass.

Her head lowered as his cock throbbed in her ass. The head was poking her asshole, spreading the cheeks. His voice was in her ears, growling and panting as her hips rose. He held her body and rolled her over, grabbing her thigh as he leaned back. She moaned and stroked the thick shaft. The wet tip poking at her soft cheeks.

"Daddy~" her fingers squeezed and fondled her breast and the other reached for his hand on her breast, pulling on it. The pleasure and anticipation grew higher, the two were lost in each other as she felt her skin touch him. Her panties were rubbing over the soft skin. She pulled her hand away to squeeze the breast. She rolled and arched her back, his cock sliding over the soft flesh. He thrust into her ass.

"AHHN!! AHHN!!" She panted. Her knees were weak, and she fell backward onto his body. The shaft of his cock slid over the cleft between her ass cheeks, her hole pressed to it, and he stroked the length of his dick, thrusting it into her. Tifa gasped, his fingers pinched her nipples and her back arched. Her hips rose.

The thick head was pushing against her anus. It slipped between her ass, stretching her. Tifa raised her ass, pushing them against her fingers, that were in her pussy, "Yes! Yes! Yes~!! Daddy," she breathed out.

"You have such a fucking monster cock," she cooed.

"Tifa..."

"Daddy, cum inside my ass~!" Tifa felt her orgasm getting closer, her cunt clamped down on the finger that rubbed the wet fabric over the slit of her pussy, the thick cock pressing between her ass, "Cum inside your Daughter's tight ass. Let your little girl take that huge fucking load from Daddy!"

She could barely hear herself when the orgasm rippled through her, and her juices spilled, flowing out of her, staining her underwear and thighs. She squeezed her eyes shut, moaning loudly when her father groaned and came in her ass. Her eyes fluttered and she cried when his fingers squeezed and pinched her nipple.

He held her up and Tifa could only whimper as she felt the tip press on the rim of her asshole. He was still coming, and he held his cock inside, shooting ropes of thick, gooey and creamy white cum in her tight ass.

"Oh...my God," Tifa moaned and cried as her body shook in pleasure and he slowly stroked and rubbed himself off, making his cum spurt inside her. He held his cock and pulled it out from between her soft ass. He held her waist as his hips kept pushing against hers.

His shaft was covered in her cum, dripping with her juices, his hand and cock stained white. She lay down in his arms, breathing heavily and resting, and her panties were wet with her juices and the cum that he had poured in her. Her hands stroked down to the wet panties that clung on to the slit.

Aurum cupped her chin, her face flushed with embarrassment, her hair clinging to her face, her lips quivered and her body was shivering, her nipples were stiff, "father sounds better to me..." she came down from her high.

"Does it?" Aurum clasped her cheek. She kissed his palm, and her hand slid up from his chest. Her head tilted to the side and her eyes lowered as she gazed up at him, "Father..."

"Not me, sweetheart. I do have an idea to your future now."

A Little While Later,

Augustus entered the Throne Room, receiving a message from King's messenger that his presence was required in the Throne Room. Though, when he arrived, he wasn't expecting to find Tifa lying on King's arm, whose throne had changed to his will again, becoming wide enough for him to support himself on his elbow.

His eyes went towards Tifa, who looked mostly naked, her thighs bare. Her dress and black stockings had fallen off. Her breasts were bare. She had fallen asleep in the crook of his elbow, with her hands over his arm and her head rested on his chest. She looked happy, satisfied, and exhausted. Her black hair fell around her head and shoulders.

"She has become a Vanguard?" Augustus noticed the qualitative change in her Aura. His voice was hushed.

"Yes. She has potential," Aurum stroked Tifa's waist, "I have been thinking about her future. I want you to adopt her."

"Adopt her?" Augustus raised his brow, "I am too young for that."

"Come, Augie," Aurum rolled his eyes, "at our Phase of Strength, we don't age. After I reached my Prime Condition, age stopped mattering to me. It doesn't matter now or 100 years later. Nothing would change, body, mind or soul. I won't become more mature or anything. Doesn't the same go for you?"

"I never thought about this," Augustus placed his hands in his pocket, "Not everyone is strange like you, ready to accept any change and move forward with that change in mind."

"Adaptive you mean."

"That's not adaptation," Augustus sighed, "you just love too much."

"Will you accept her," Aurum kissed Tifa's head, watching her sleep, tucking her hair back.

"If I do? What then?"

"In the future, when Cloud goes on an expedition. She can stay by his side."

"You want her to be a Deputy Expedition Leader?" Augustus understood. He felt a headache coming, "You have to crazy. Every noble in this Kingdom is fighting to lead an Expedition. These worlds are a never ending gold mines and while the Phase 1 and Phase 2 Worlds have niche powers, they are powers nonetheless. Their monetization and entertainment value are priceless. Let alone, ruling one of them might grant one enough Aura to reach Phase 3."

"And you want to give that chance to Once Human? Do you want a revolt at your hand?"

"Dare they?" 

"How would you be any different from Uther then?" Augustus narrowed his eyes, 'they certainly don't dare.' 

"It's a Phase 0 World that was sealed off in time because of its Unique Fate. I didn't have a solution then, but I have now. They will be my Vanguards on the Mission."

"A Phase 0 World?" Augustus thought, "Sure, the chance of getting anything worthwhile there is minute, considering they don't even have Magic, Cultivation or Aura there. There's nothing in there. That's just asking to be kicked down the social ladder. Do you really think you have thought this through? The people will just consider it as an excuse for a vacation," Augustus's gaze fell on the King.

"That is an interesting world in its own right. I have my plan for it, and them. It's not popular. That doesn't mean no one wants it. There are Nobles who would want to cultivate that world, invest hundreds of years to cultivate that territory, knowing they could reach Phase 3 in the Future with its help."

"Which is why you want me to..." Augustus breathed out, "adopt her."

"Will you?"

"Do I have a choice?"

"Augustus," Aurum happily smiled, "I always give a choice."
