They stepped through the narrow cave mouth expecting damp stone and darkness.
Instead, warm golden light poured over them like sunrise.
The tunnel opened after only ten meters into… impossible space.
A vast, lush valley stretched before them: easily several square kilometers, ringed by sheer cliffs that rose into a perfect circle of blue sky far above. Waterfalls cascaded down the cliffs into crystal rivers. Ancient cedar and sakura trees towered overhead, their branches heavy with blossoms despite it being November outside. The grass was emerald and knee-high, dotted with wildflowers that released sweet perfume into the warm air. Butterflies the size of dinner plates drifted lazily. Birds with impossible jewel-colored plumage sang from the branches.
Sayuri's hand flew to her mouth.
Mika's grip on Kai's arm tightened until her nails dug in.
Kai just stared, heart hammering.
"What… what is this place?" Sayuri whispered.
Mika took a cautious step forward, then another. When she reached the edge of the grass, she knelt and ran her fingers through it. "It's real. Warm. Alive."
Kai turned back to the cave mouth. The stone archway still shimmered faintly, like heat haze. He stepped through it: back into the cold, normal forest. One more step and he was back inside the valley. The portal worked both ways.
"It's a pocket world," he said, voice hushed with awe. "A hidden dimension. I've read old stories about places like this: sacred spaces, paradise realms, things the kami left behind."
Sayuri's eyes were wide. "We can come and go whenever we want?"
"Looks like it."
Mika stood slowly, turning in a circle, taking in the waterfalls, the distant mountains that shouldn't exist, the perfect untouched beauty of it all.
Then she looked at Kai.
And Kai looked at them both.
The same thought hit all three of them at once, electric and inevitable.
This place was untouched.
Virgin earth.
No one had ever walked here before them.
No one had ever loved here.
Kai's voice came out rough. "I need to claim this place. With both of you. Right now."
Sayuri's breath caught. Mika's pupils blew wide.
They didn't need words.
Clothes came off in a frenzy.
Sayuri's dress fell first, pooling at her feet, revealing her seven-month pregnant body in all its fertile glory: heavy, milk-swollen breasts with dark areolas already beading with the first drops of colostrum, round belly glowing in the golden light, thighs thick and soft.
Mika stripped next, overalls and tank top discarded, sun-browned muscles flexing, breasts heavy and free, nipples stiff in the warm breeze.
Kai's shirt and pants followed, his cock springing up thick and urgent, already leaking at the sight of his two queens naked in this sacred, impossible place.
He laid them down in the grass: soft as silk, warm from the hidden sun.
First Sayuri.
He spread her gently on her back, the flowers cradling her like a bed made for a goddess. Her legs fell open naturally, pussy already glistening, swollen from pregnancy and arousal. Kai knelt between her thighs and entered her in one slow, reverent thrust.
Sayuri cried out, back arching, hands clutching the grass as he filled her completely. The angle with her belly made every stroke rub perfectly against her front wall. He fucked her slow and deep, one hand splayed over the curve of her stomach, feeling the life they'd made together move faintly beneath his palm.
Mika watched, fingers buried in her own pussy, eyes dark with hunger.
When Sayuri came the first time (quiet, shuddering, tears of overwhelming pleasure on her cheeks), Kai pulled out gently and turned to Mika.
He took her on her hands and knees in the grass, the way she loved best: raw and powerful. Gripping her hips, he slammed home in one thrust. Mika growled, pushing back, meeting him stroke for stroke. Her strong back arched, braid swinging, breasts swaying heavily beneath her as he pounded into her like he was trying to brand this new world with their love.
Sayuri recovered enough to crawl beneath them, lying on her back so she could lick Mika's clit while Kai fucked her. The combination broke Mika in under two minutes: she screamed, body locking, pussy spasming so hard around Kai's cock that he had to fight not to come.
He pulled out, cock shining with both of them, and laid back in the grass.
They took turns riding him.
Sayuri first, facing him, belly between them, breasts bouncing gently as she rolled her hips in slow circles, grinding her clit against his pelvis. Kai reached up to milk her breasts, catching the thin streams of colostrum that leaked from her nipples and bringing them to his mouth. The taste (sweet, warm, alive) made him thrust up harder, and Sayuri came again with a broken sob, pussy fluttering around him.
Then Mika mounted him reverse, powerful thighs flexing as she sank down to the root. She rode him hard, ass bouncing, back arched, head thrown back so her braid whipped against Kai's thighs. Sayuri knelt in front of her, kissing her deep and filthy, fingers rubbing Mika's clit in tight circles until she came with a roar that echoed off the cliffs, squirting so hard it splashed Kai's stomach and the grass beneath them.
Kai finally lost control.
He flipped Mika onto her back beside Sayuri, spread both women's thighs wide, and took them in turns: three deep thrusts into Sayuri, three into Mika, again and again, until both were sobbing and begging.
When he couldn't hold back anymore, he buried himself in Sayuri first, pumping rope after thick rope deep inside her womb, marking the mother of his children in this sacred place. Then, still hard, he pulled out and slid into Mika, filling her just as full, claiming both of his queens in the same breath.
They lay there for what felt like hours, tangled together in the grass, bodies sticky with cum and sweat and flower pollen, the warm breeze drying them gently.
Sayuri traced lazy circles on Kai's chest. "This place… it's ours now, isn't it?"
Mika nodded against his shoulder. "We christened it properly."
Kai looked up at the impossible sky, feeling the weight of what they'd discovered settle over him like a blessing.
A secret world.
Untouched.
Eternal spring.
Hidden from time itself.
And they were the first: the only: to love here.
He pulled them closer.
"We're going to come back," he said quietly. "Again and again. This is our place now. Our paradise."
Sayuri smiled, hand resting on her belly. "A place where our children can run wild and free."
Mika kissed his jaw. "A place where we can be as loud as we want."
Kai laughed, the sound echoing across the valley.
They dressed slowly, reluctantly, stealing kisses and touches, already planning the next visit.
When they stepped back through the portal, the cold autumn forest felt dull by comparison.
But they carried the warmth of that hidden world on their skin, in their hearts, and deep inside where Kai had left his seed.
The cave had been waiting for them.
And now it belonged to them forever.
