Myriad Heavens: Rise of the Rune God

Chapter 321: Chapter 322: Breakthrough Guidance **r18

After several more days of drifting between universes—watching newborn stars bloom, walking the edge of collapsing realms, and letting Celestia and Nyla pull him into quiet corners for soft kisses that always threatened to turn into something hungrier—Runar finally stopped in the middle of a silent starfield.

Celestia floated on his left, silver hair drifting in the weightless dark. Nyla hovered on his right, one hand already hooked loosely in the front of his robes like she was thinking about yanking him somewhere private again.

”We’re taking a short detour,” he said.

Space folded under his palm like silk. A seamless rift opened, spilling warm golden light and the faint scent of rain on spiritual grass. He guided them through. The rift sealed behind them without a ripple, erasing every trace.

The pocket dimension was deliberately intimate.

Auroras drifted overhead in slow, lazy rivers of violet and soft gold. The ground underfoot was a living carpet of spiritual energy that felt like cool silk and warm moss at once. In the center of a gentle hollow stood a wide, low bed woven from condensed cloud and spiritual silk—soft enough to sink into, strong enough to hold whatever they did to it. The air itself was thick with pure energy, perfectly sealed, perfectly private. No laws of the Multiverse could reach them here. Only his will.

Runar turned to face them. That familiar calm expression sat on his face, the one that usually meant he had already thought three steps ahead of everyone else.

”I’ve been thinking about your cultivation resources,” he began. ”I could snap my fingers and create pills or liquids so pure most Multiversal cultivators would start a war over a single drop. But I have a better idea.”

He stepped closer. His voice dropped into something lower, rougher, teasing.

”Instead of external resources... you take them directly from me. My essence is denser and purer than anything I could refine. Every time I spill inside you, it will temper your bodies, expand your dantians, and feed your principles. And while you’re taking it, I’ll lecture you on Dao. You’ll comprehend and advance even while you’re—”

Nyla’s eyes lit with open, hungry fire.

Celestia’s lips curved into a slow, dangerous smile that promised she had been waiting for exactly this.

They didn’t let him finish.

Nyla moved first.

She grabbed the front of his robes with both hands, yanked him forward hard, and crushed her mouth against his. Her tongue pushed past his lips without hesitation, tasting him like she had been starving for days. Celestia stepped in from the side at the same moment, fingers already working his belt open with the calm, practiced efficiency of a woman who had decided the waiting was over.

”Finally,” Nyla muttered against his mouth between deep, greedy kisses. ”Do you know how long we’ve been waiting to properly take you?”

Celestia pulled his outer robes off his shoulders and tossed them aside like they were an inconvenience. ”You keep running around the Multiverse becoming more and more ridiculous. We decided we’re not waiting any longer.”

Runar’s back hit the bed of cloud and silk. Both women followed him down without giving him room to breathe.

Nyla straddled his chest immediately, already peeling her own clothes off and flinging them away. Celestia finished stripping him completely—robes, underlayer, everything—until he lay bare beneath them. Then she shed her own robes in a few smooth, unhurried movements, silver hair cascading over one shoulder as she looked down at him.

When they were both naked, they gazed at him with matching predatory expressions. Two women who had wanted this for a long time and were finally taking it.

”So,” Nyla said, wrapping her fingers around his already hard cock and stroking him slowly, thumb brushing over the head, ”your big idea is that we use your cum as our main cultivation resource?”

Celestia leaned down and licked a slow, wet stripe up the side of his neck, teeth grazing skin. ”And we have to listen to Dao lectures while we do it?”

”Yes,” Runar answered, voice calm even as his cock twitched in Nyla’s hand. ”That’s exactly the idea. You’ll take everything I give you. And you’ll listen while you do it.”

Nyla grinned, sharp and delighted. ”Cute.”

She didn’t wait for permission.

She shifted forward and sank down onto his face without another word, pressing her already wet pussy directly against his mouth. The heat of her, the soft slick folds, the way she settled her weight exactly where she wanted it—all of it was deliberate.

”Then start lecturing,” she ordered, one hand sliding into his hair and gripping. ”And don’t stop licking.”

Celestia moved lower at the same time. She took his cock in her hand, lined him up, and sank down onto him in one smooth, unbroken motion, taking every thick inch until her ass rested fully against his hips. A soft, satisfied breath left her as she adjusted, feeling him stretch her open.

”We’ve wanted this for a long time,” she said, beginning to ride him with slow, deliberate rolls of her hips. Deep. Controlled. ”You can give all the lectures you want. We’re still going to milk you dry.”

Runar’s inner thoughts stayed cool and faintly amused even as their bodies closed around him.

They think they can dry me out.

Cute.

They’re nowhere near my level. My essence regenerates faster than they can take it. At this rate they’ll exhaust themselves long before I even feel strained.

Out loud, he began to speak between the wet pressure of Nyla’s pussy on his tongue.

”Energy conversion... starts with density,” he managed, voice steady despite the way Celestia was already clenching around him. ”The denser the essence, the less waste during absorption. My current purity level... is past what most Multiversal cultivators can even perceive. Every drop I give you will rewrite your meridians if you guide it correctly.”

Nyla ground down harder, laughing breathlessly. ”Keep going. Don’t you dare stop.”

Celestia rode him with slow, deliberate rolls, hands braced on his stomach. ”We’re listening, husband. Don’t hold back.”

They took him exactly how they wanted at first.

Nyla used his mouth without mercy, hips rolling, fingers tight in his hair. Celestia rode his cock at her own pace—sometimes slow and deep, sinking down until he was buried to the hilt and grinding in tight circles; sometimes hard and bouncing, the wet slap of her body against his filling the quiet pocket dimension. Every time he came, Celestia sank down fully and held him there, grinding so every thick, glowing spurt was pumped as deep as possible into her womb. She moaned softly as the pure, scorching essence began spreading through her meridians—hotter and denser than any pill she had ever taken.

”That’s it... give it to me,” she whispered.

Nyla laughed and switched places the moment Celestia loosened her hold. She pushed her sister-wife aside, straddled Runar’s hips, and sank onto his still-hard cock with a long, greedy sound.

”My turn.”

She rode him harder. Hands on his chest, hips slamming down. Celestia moved up and sat on his face the same way Nyla had, already dripping with his cum and her own release.

”Don’t stop lecturing,” Celestia ordered, voice soft but absolute. ”We’re still cultivating.”

Runar kept talking.

Even while Nyla bounced on his cock and Celestia soaked his face, he forced the words out—explaining principle resonance, how extreme density of energy could force open new pathways, how the body itself could be rewritten into a better vessel if tempered correctly. His voice stayed calm, analytical... except for the rough edges that slipped through every time one of them clenched around him deliberately.

They’re trying so hard to empty me, he thought, faintly amused as another thick load flooded into Nyla. They have no idea. My recovery is instantaneous at this level. They’ll be the ones shaking and spent long before I even start to feel it.

Days blurred inside the pocket dimension.

The sex was never normal.

You might wonder how two Multiversal cultivators—and one being who stood outside the Multiverse entirely—could ever grow exhausted from something as simple as physical intimacy.

It was not simple.

Every thrust, every roll of hips, every deep grind happened at speeds measured in billions of times faster than light. Time itself stretched and folded around them. The energy exchange was so violent that each climax sent shockwaves through the pocket dimension that resembled miniature Big Bangs—contained only because Runar’s will refused to let the private world shatter. Universal-scale explosions of pure essence and principle force bloomed and collapsed around their joined bodies again and again, lighting the auroras overhead in violent, beautiful colors. The sheer volume of energy being transferred, converted, and absorbed would have vaporized ordinary Multiversal cultivators. Even Celestia and Nyla, newly risen and rapidly strengthening, felt the cumulative toll in their bones and meridians.

That was why they eventually grew exhausted.

Not because the sex itself was too much for their bodies in a mundane sense—but because they were fucking at a scale that rewrote local reality with every orgasm.

Runar never tired.

His essence regenerated the moment it left him. His hybrid body treated the endless demand as a mild warm-up. The more they took, the more he had to give.

And sometimes... he decided it was his turn to take the lead.

On the second day, after Nyla had ridden him into another thick climax and was still panting on top of him, Runar’s hands suddenly closed around her waist. He flipped their positions in a single smooth motion that left her on her back, legs spread, eyes wide with surprise and heat.

”My turn,” he said quietly.

He drove into her hard and deep, one hand pinning both of her wrists above her head, the other gripping her hip so she couldn’t escape the rhythm he set. Celestia watched from the side, lips parted, already reaching for herself—until Runar’s free hand caught her wrist and pulled her closer.

”You too,” he said.

He pulled Celestia beneath him as well, switching between them with ruthless precision—fucking Nyla until she was shaking and begging for more, then burying himself in Celestia until her silver hair was a mess and her voice broke on every moan. He held them both down when he wanted, flipped them onto their knees when he wanted, made them take him from behind while he lectured in that same calm, steady voice about energy pathways and principle fusion.

They loved it.

Nyla’s laughter turned into desperate, broken sounds every time he pinned her and took exactly what he wanted. Celestia’s usual composure cracked into soft, needy moans whenever he held her hips and drove into her at a pace that made the pocket dimension shudder with another contained Big Bang of energy. They still teased him, still tried to take control again whenever he let them—but every time he reclaimed dominance, they melted into it with pure, hungry delight.

”Keep talking,” Celestia gasped once while he had her on her hands and knees, one of his hands in her hair, the other on her hip. ”Don’t you dare stop the lecture just because you’re inside me.”

”Principle resonance...” Runar answered, voice low and rough as he thrust deep, ”requires the vessel to accept the density without resistance. You’re both doing well. Take more.”

Nyla, watching from the side with flushed cheeks and glazed eyes, laughed breathlessly. ”He’s actually still lecturing while he fucks us senseless. I love him.”

They kept switching between taking and being taken for days.

Sometimes the wives pinned his wrists and used him until they were shaking. Sometimes Runar flipped the entire dynamic and made them take everything he gave them until they were glowing, trembling, and begging for the next load. Every climax still flooded them with pure, scorching essence that tempered their flesh and expanded their dantians. Every lecture still sank into their comprehension even while their bodies were being used at speeds that rewrote local physics.

On the fourth day, the breakthroughs hit.

Celestia was on her back beneath him, legs locked around his waist, when the Multiversal threshold shattered inside her. The air cracked with the force of it. Runar drove into her through the entire violent advancement, filling her with another thick load while energy erupted around them in a controlled storm of silver and violet. Her dantian expanded. Her principles solidified. Multiversal realm locked into place with a resonance that made the entire pocket dimension tremble.

She collapsed against the bed, breathing hard, glowing, laughing softly under her breath.

Nyla didn’t wait.

The moment Celestia’s legs loosened, Nyla pushed forward, climbed on, and took him in one aggressive motion—only for Runar to flip her onto her back a few heartbeats later and drive into her just as hard. She fucked herself up against him with short, desperate rolls until her own Multiversal breakthrough crashed through her like a second storm. She came with a broken cry, clenching around him so tightly he had no choice but to fill her again. Energy flared around her in wild gold and crimson. Multiversal realm settled into her bones.

When it was finally over, both women lay draped over him, sweaty, glowing, thoroughly satisfied, and newly advanced. The air itself hummed with the residual energy of two consecutive Multiversal breakthroughs and the countless contained Big Bangs that had accompanied the days of dual cultivation.

Celestia traced lazy circles on his chest with one fingertip. Nyla stretched against his other side like a contented predator who had just eaten well—and been thoroughly eaten in return.

Runar exhaled slowly, arms wrapping around both of them. His voice was still rough from days of lecturing through every climax.

”From Multiversal realm onward,” he said, ”you walk your own path to Paragon. I can support you. I will give you inheritances tailored to each of you. But the final comprehension and the will required... those have to be yours.”

Celestia lifted her head and kissed the corner of his mouth, soft and warm. ”We know.”

Nyla smirked, still catching her breath, one leg thrown possessively over his. ”Just make sure you’re available when we need more ’resources.’ And... when you decide to take over again.”

Runar looked at the two newly advanced Multiversal cultivators who had spent days trying—and failing—to milk him dry, only to end up the ones exhausted and glowing with his essence. For once he had no immediate reply beyond a quiet, dry smile.

Outside the pocket dimension, the Multiverse continued turning, vast and indifferent.

Inside it, Celestia and Nyla slept against him—full, powerful, thoroughly used and thoroughly using, and very pleased with themselves—while the residual energy of their breakthroughs slowly settled into something permanent.

The vacation was far from over.
