Chapter 343-346: Mating Ceremony (R-18)

It's been 100 chapters since I wrote smut. Any feedback is appreciated xD.

Though I know most people would rather have plot instead of 'plot.' 

***

Asahi took the girls down to the 59th floor. The forest was eerily silent. Asahi couldn’t feel a single life form on the entire floor.

“It’s like a safe floor now,” Nao mused.

Saeko had a deep frown on her face as she looked around. “Something feels off.”

“It does!” Shiori threw herself at Asahi and squeezed his arm. “My horror meter is buzzing madly!”

It was all an excuse to be intimate with him in Saeko’s presence. Everyone knew that, yet no one pointed it out.

“There is no one here,” Asahi said and checked the time on the watch given by his devil maid. “It’s time for dinner.”

“We should return then,” Saeko said. “Rika-san will be angry if we explore the legendary 60th floor without her.”

“I’m more interested in the 69th floor,” Shiori said, giving Asahi a wink. “Aren’t you as well, dear?”

“Of course.”

Ray silently tried to understand their back and forth, but she couldn’t understand one thing. “Why is the 69th floor special? Has Master been there before?”

Shiori released his hands as though knowing his next action. Asahi stepped past Nao and wrapped Ray in his embrace. Ray’s ears twitched as she felt his warmth.

“You’re too adorable, you know. I’ll show you 69 later.”

He could imagine Ray doing her best to jerk him with her wings. It aroused him more than it should, oddly so.

‘My lust is going out of control!’

(Don’t worry. You have us to take care of your needs.)

“Uhm…” Ray nodded meekly, unknown to his lustful thoughts.

Asahi glanced at Rini who gazed at him, her eyes filled with passion. Her skill was acting up again. Asahi reached out and patted her head. She couldn’t help but feel a little lost as the desire to mate with him got out of her head. At the same time, she was reminded of the first time she met him. He patted her head in the same way when she had nowhere to go.

“Onii-san…”

Asahi patted her cheeks. “Let’s continue it later.”

Rini could barely hide her surprise at being seen through. Then again, he was always there whenever she lost herself to the rage.

‘He understands me the most…’

She let him spoil her while Shiori gave her an envious look. Rini pretended not to notice her and indulged in his headpats.

Once Asahi was done, he returned home and let them shower. He found the girls watching an anime on the television. The meeting room had no wooden chairs now. Only shiny leather couches could be seen. Every female in the Familia was here, including Rika and Grayfia. Astraea waved at him with a bright smile before she turned her attention back to the shonen anime.

“My Lord, we were waiting for you,” Grayfia said and distance herself from Rika.

Asahi sat between the two and rested his head on Rika’s shoulder. “What were you doing?”

Rika wrapped his head around his head and stroked his hair. “Meeting Natsumi.”

“Huh? Why would you?”

Rika smirked. “Don’t be so cold. She’s been standing at the city gate for hours. People were panicking because a level 4 adventurer was keeping watch on the gate. Someone had to go and stop her.”

“Is she an idiot? I thought she’d use her wolves for the job.”

“Not an idiot. A devoted slave,” Rika said and pecked his forehead. “I’m more obedient than her, Master~.”

“You sure are,” Asahi said and cuddled with her.

The scene of Rika spoiling him caused a little commotion among the adventurers. Soon everyone returned to watching television except for Ryuu who kept staring at Asahi with an odd look in her eyes.

Feeling Ryuu’s intense gaze, Asahi couldn’t help but look in her direction. The elf smiled; the instinctive reaction embarrassed her.

Asahi chuckled and caressed her cheeks with his telekinesis. Ryuu gave him a glare, which only looked adorable with her red cheeks.

‘What if I touched more than her cheeks?’

Asahi wondered about her reaction.

Nobody noticed Kaguya’s smirk in the background.

***

After an uneventful dinner, Asahi returned to his room. The emperor-size bed was empty as though the girls predicted his meeting with Rini.

‘Rini might have told them.’

Asahi sighed and plopped down on the bed. Rini had promised to come to him. She might be gathering her courage for her first time, or so he thought.

‘What do I do…?’

(How about you read the Grimoires to unlock more elements?)

‘Sounds good.’

He took out his good ol’ Grimoire to learn more about the elements. He hadn’t touched the Grimoire for a while despite the benefits it offered. After all, the headache it brought forced him to rest.

(With your increased mental strength, my love should be able to finish it now.)

‘Let’s try.’

He opened the Grimoire and immersed himself in the divine language. He had left the book at the Wind Element section, which wasn’t that hard to comprehend. Baal and Amon’s spells made him more than familiar with the Wind Element. Usually, ten minutes of reading made his temples painful. But he felt none of the side effects. Thus, he kept going until he reached the end of the Wind Element part.

[—‘Elemental Roulette’ ranked up to C.]

[—You have unlocked the ‘Wind’ Element.]

“I’m gonna keep going. The next part is…”

Earth Element. Yuriko was rather proud of being the sole member possessing the defense-focused element. Though nowadays she was more proud of the store she had built in less than a month.

Without any side effects, the section was finished before long.

[—You have unlocked the ‘Earth’ Element.]

[—Rewards: +1 point in all attributes, +10 points in Defense attribute.]

He flipped another page to find a detailed illustration of a bolt of lightning striking the ground.

‘Shiori will love this. Come to think of it, nobody has the lightning element in my harem.’

He didn’t see anyone with the lightning element in his previous world either. Even in the Danmachi world, nobody wielded the power of thunder. Zeus and Ouranos weren’t counted due to their divine powers.

‘Bell did. Well, his firebolt was a mix of lightning and fire.’

(Saeko might awaken it. She is a quick thinker.)

‘Water and lightning. A lethal combo to electrocute her foes. Another way to torture.’

He got back to reading. As he finished the last page, a jolt of hot electricity rushed up to his spine. He sat upright, his eyes wide in surprise.

[—‘Elemental Roulette’ ranked up to B.]

[—You have unlocked the ‘Lightning’ Element.]

[—Rewards: +1 point in all attributes, +30 points in Perception attribute.]

“That’s an upgrade?”

“That’s new. Show me the descriptions.”

(Hai!)

“This is magician class on crack.”

(And this.)

[‘Multithreaded Processing’ and ‘Instincts’ can be evolved into a Special-Rank skill.]

[Requirements — 350 Dexterity, A-Rank Multithreaded Processing, A-Rank Instincts.]

‘A-Rank skills and 350 dex… you upgrading them to omniscience or what?’

(Not entirely omniscience. A little inferior...)

‘Time for godhood, huh.’

He wasn’t much different than the gods of the DxD world at this point. Klyscha was still a goddess on a different scale, so he never compared herself to any gods in existence.

(We are one step closer, my love.)

‘Indeed. I shall grab your real ass one day.’

(Umu… she is here.)

Asahi also sensed two presences outside his room. Did Rini bring a friend?

*Knock!* *Knock!*

One of them ran away after knocking on the door. The muffled footsteps belonged to Ray.

‘What is going on?’

Asahi opened the door and gaped. A blue present box stood in the lonely corridor of the shrine. Wrapped in light blue ribbons, the gift was nearly as big as him. Sensing the person hidden inside the box, Asahi revealed a mischievous smile.

“Huh. I got a big present. Was it meant for my birthday?” Asahi thought out loud and patted the box. The box stirred a bit. “It moves!”

Asahi wrapped his arms around the box and dragged it inside. He intentionally locked the door with a snap and slowly pulled the ribbon.

“Whoever is inside, can you hear me?”

He muttered as he pulled up the box with telekinesis. He almost got a nosebleed from Rini’s new outfit. A black and white frilly bikini covering her chest and groin qualified as a maid dress. The black stocking stretching to her fair, athletic thighs made Asahi gulp.

“O-Onii-san,” Rini said and straightened her posture. A haze of lust crept into her mind, but she pushed it back with her willpower. She clasped her hands on her lap and bowed. “Your birthday p-present is here.”

Asahi raised her chin with his finger and pecked her lips. “Most wonderful birthday gift of my life.”

Rini shuddered as his warm breath caressed her face, his acceptance sending a pulse of delight through her. Seeing his gentle self, Rini felt a strong urge to push him down right here and now.

A berserker or not, she was a woman. His beloved sister, who treaded between monster and human.

The more Asahi accepted her for who she was, the more she leaned into the monster side. Tapping into her monster side filled her with strength. But it brought another agonizing problem.

Mating.

Even before she matured from her petite body, she had these desires to touch him. She usually suppressed them until night arrived and her friends started moaning in the room beside hers.

The cries of women bathing in her brother’s love had driven her crazy.

Yet that feeling couldn’t be compared to her current passion.

Her very soul ached for his touch, her nether regions wet with carnal desires. Nothing else entered her mind as the sensations had blurred her thoughts.

“Onii-san… I’m here to get cured… I can’t stop now. Please… help me,” she looked up with teary eyes. “Make love to me. Make me your mate...”

From the day she heard the women in her family moaning after the birthday, her body was unsatisfied no matter how much she soothed herself.

Feeling her fierce yearning, Asahi cupped her cheeks and ran his thumb over her lips.

“Gladly.”

She leaned back slightly and raised her gaze, offering her lips once again. He gave another kiss as he entwined his fingers with hers.

Maybe it was the deep kiss or the fierce union of their hands that flared Rini’s lust. She released a burst of fragrance that aroused Asahi until his cock woke up and strained against his shorts. Any man in his position would have done the same as her charm had skyrocketed, nearly to Ishtar’s level.

The intricate dance of their tongues only stopped Rini when she was completely out of breath. Asahi brushed his cheeks with hers before he descended. Rini shuddered softly as her brother pressed his lips on her nape, sucking them as though he found them enticing.

“You climaxed last time with a kiss,” he said.

Rini blinked her eyes, tilting her head. Her lust-filled mind took a whole moment to process his words. When she did, she was all red, huffing adorably.

“I touched m-myself.”

She couldn’t find different words to explain her agonizing nights. The act of self-pleasure gave her some resistance, enough to hold back her gushing juice during the kiss.

“Oho, my imouto has become naughty.”

Rini nodded blankly, her fingers reaching out to his pants. She found his cock pulsating with warmth even under his shorts. Her eyes lit up in anticipation. She hastily pulled his shorts and wrapped her fingers around its girth.

Asahi trailed his finger along her thighs, receiving a pleasant shiver from Rini. His hands dove into her frilly maid skirt and caressed her gushing slit.

“Hurry,” a muffled plea escaped her lips as she caressed the crown of his member. “Onii-san.”

Since she was wet enough, Asahi decided to skip foreplay this time. He never needed one but flirting and teasing his women got him more into the mood.

He pulled up his shirt and tossed it aside. Not wasting another precious second, he picked her up and walked toward the bed.

Every second seemed like an eternity in Rini’s eyes as the bed appeared closer.

Asahi put her down and patted her cheeks. Rini snapped out of her daze and took a long look at his erect cock. She gulped forcefully, enough for Asahi to hear it. It was bigger and thicker than what she felt in her hand.

“C-Can I make a request?”

“Of course.”

Rini raised her upper body with her elbows support and turned her body. Standing on all fours like an animal, she felt shivers of pleasure. The pleasure that came from being gazed at by her beloved in such an embarrassing position.

“Do me like this…”

Her monster instincts compelled her to do this. She imagined her first time with him in the same position. Nothing else seemed more ‘right’ to her.

Asahi cracked a smirk. The adorable frills clenched her wide hips, and her legs were parted just enough for a breeze to pass through. The stains of her desires could be seen on her wet panties. Asahi wanted to do more than just fuck her, but he held back for the sake of his sister. Her aroma or rather her pheromones were increasing with each passing minute. It was an invitation from her. An invitation extended to her mate to ravage her.

He had to satisfy her.

He trailed a finger on the soft skin of her butt. Rini’s breathing became labored as her brother pushed the only cloth between him and her holes. The heat in her abdomen came to the breaking point, crying for a release.

Begging for him to penetrate her.

Asahi stretched her fleshy mounds. The strands of her juices created a web between her lips. Her bright pink, beautiful flower came under his passionate gaze. Rini clenched at the prospect of being watched so intently. Asahi pushed a finger inside her furnace-like heat, forcing a tiny moan out of Rini.

‘It won’t be a problem.’

He intentionally left her dressed, if her current outfit even qualified as one. He threw his shorts and aligned himself with his sister’s hole. He rubbed his cock on her slippery pussy. As though knowing what he wanted, her pussy oozed thick juices onto his thick member. Rini separated her knees and raised her butt for her brother to see.

Asahi pulled back before he probed her luscious slit and shoved his tip inside her. Her blazing warmth enveloped his cock. She was truly in heat. The fact couldn’t be denied.

Rini’s back arched, and she gasped, her face contorting in pleasure. Her dripping insides fluttered and quivered before locking him down like a vice.

“Oh, Onii-sama!” Her eyes welled up with tears. Tears of pure joy slid down her cheeks. She finally bridged the gap between the brother and sister bond into a true lover’s bond.

Asahi leaned forward until his cheeks brushed against her hair. He pulled her in for a kiss, which she happily reciprocated. Her nipples hardened even more as Asahi’s fingers landed on her tits. He slipped his hands inside her black frilly swimsuit and rubbed her cherries.

With another movement, Asahi slammed himself to the hilt, finding literally no resistance as though she was born ready for this moment. Ready to breed with him.

Rocking his hips, he began hammering away into Rini’s pussy. Powerful vibrations tunneled down his throat as Rini howled pleasurably into his mouth.

Asahi caressed, kneaded, and showered his sister’s scrumptious breasts with all the love he could channel into his fingers. He showered every inch of her fair neck with hickeys before he pulled back. His fingers dug into her meaty butt. The big, fat flesh of her bottom easily sank against his warm palms.

He tried to be gentle in his movements, but Rini sank until her breasts touched the fluffy mattress.

“Hnghhh. Yes! More, Onii-saaaan! Hard. Harder!”

She was lively in her movements as though she hadn't lost her virginity moments ago. Her instincts wanted him to be rougher. It satisfied her heat. It made her feel more intimate with him.

Asahi was a little surprised by her wildness. Though it didn’t last long. He resumed pounding her glorious body. Her mind was slammed with pleasure. The few words that escaped her mouth pleaded for more. He obliged his sister’s request and attacked her G-spots with his glistening cock.

It took another few thrusts before Rini climaxed with a scream. Still obeying her desires, he kept moving. Something that sent larger waves of ecstasy into her mind driven by carnal desires. The spasms in her legs escalated several levels under his rough pounding.

He ripped the swimsuit covering her chest. Taking her hands, he pulled her back. Her flexible back arched at an unusual level, and he groped her breasts. The ripe and juicy tits contorted under his warm hands.

Rini went through several peaks in a matter of a few minutes. Only when another one approached, did Asahi feel a surge gathering at his tip.

“I’m cumming,” he groaned.

“Please!” Rini pushed back desperately. “Inside! INSIDE!”

Her fierce shouts echoed. Asahi grabbed her hands and slammed his dick inside. His orgasm finally hit, and he came inside her.

Rini tightened in bliss but the pressure around his shaft kept building up.

“Take it out!” Rini gasped, her eyes widening in pleasure.

Asahi quickly pulled back and gently released her arms. She collapsed on the bed and turned over. Her face broke into a blissful smile as she separated her legs, giving him a clear view of her mature pussy.

“Thank… God… I warned Onii-san.”

Asahi spotted zero traces of cum flowing out of her pussy as though her hole had shut itself to savor his seed.

(That’s what happened, my love.)

Asahi breathed a sigh of relief. His life element had done its job. Rini had no chance of getting pregnant this time.

‘She is too young.’

He observed his sister’s naked form again. Her abs called for a caress, each one impressive in its own right. Her breasts were smooth and supple, more than enough to spill out of his hands. Her fair skin glistened in sweat produced from their hard work.

His little sister stretched her arms, her elbows squishing her breasts under her.

“Onii-san, I need more.”

The lovely gesture hardened his half-erect cock.

He obliged with a nod and pressed Rini into the mating press. Her womb opened again, giving him another pass into her slippery hot hole.

He suckled on her breasts, which tasted sweet and salty at the same time from her sweat. He gave them the love they deserved, pulling at her rosy nipples with his nipples, sometimes using his teeth.

Their union kept going on for hours. Every time he came inside, her pussy would shut itself. Overcome with curiosity, he asked her the deal with it.

“I-I think… I have an organ for storing… semen.”

Asahi’s surprised expression made her giggle. Tracing her hands on his solid muscles, she pecked his neck.

“Onii-san… more?”

She had already broken Grayfia’s record. Yet, she wanted more.

That day Asahi realized even a Devil, a being embodying the seven sins more than humans, couldn’t be compared to a half-monster in lust.

If Rini was a hawk, then Grayfia was a mere chicken. The massive difference came from Rini’s mating ceremony skill as it allowed her to keep her sexual desires topped up whenever Asahi was near.

Of course, Asahi showed her defeat all the same even though it took nearly seven hours on constant pounding to satisfy her heat.***

Gonna write two chapters of Fate for tomorrow.
