Forbidden Women Only Empire Where NO Man Could Set Foot. [Eden’s Vault]

The heavy wooden door to Stheno’s chamber slammed shut behind Medusa and Euryale, leaving only the sound of their fading footsteps and Stheno’s embarrassed hiss echoing in the room.

Stheno smacked Hyun-woo’s chest with the flat of her hand.

“You bastard!” she growled, her face burning bright crimson all the way to the tips of her snake-hair. Even the smaller vipers seemed embarrassed—which he didn't know was even possible, but it looked incredibly cute. “You forgot to lock the door!”

“I was a little busy!” he shot back, grinning shamelessly despite the situation.

The next thing he knew, Stheno grabbed the solid wood bedside table and hurled it at him.

BAM!

Hyun-woo barely dodged it in time.

“Hey! Are you insane?!” he laughed, quickly scrambling up from the bed.

Stheno tried to follow him but immediately failed. Her legs—or rather, her tail—refused to cooperate. After hours of intense sex, her body was trembling and weak.

Hyun-woo noticed but wisely didn’t say anything.

“Hey,” Stheno called out, sounding slightly annoyed.

“Yes?” He turned. His cock was still rock-hard, bouncing slightly with the movement despite the all-night marathon.

“Aren’t you tired after fucking all night?” she asked, genuinely curious.

“I will never get tired of having sex with you,” Hyun-woo replied cheekily, flashing her a playful grin.

Stheno just stared at him. What the hell, dude? she thought, but didn’t say it out loud.

Instead, she sighed. “…Pick me up, please. I can’t get up.”

Hyun-woo didn’t hesitate. He scooped her up easily into a princess carry. The moment he lifted her, thick globs of his cum leaked out of her pussy, dripping down her golden scales and onto the mossy bed.

Stheno’s eyes widened. “Just how much did you fucking cum?”

“I think that’s average,” Hyun-woo said seriously, using the flawless logic he had learned from h-mangas.

You think that’s average?! Stheno thought, but kept it to herself.

“…Shower. Now,” she muttered, her cheeks still flushed. “I’m not facing my sisters smelling like sex—” she sniffed the air, “—and sweat.”

Hyun-woo chuckled and carried her toward the attached bathroom. Stheno whimpered softly with every step he took, her body still extremely sensitive.

Stheno’s private bath was beautiful—a spacious pool naturally carved into the living wood of the tree. Warm water bubbled up from an underground spring, glowing faintly with golden mana motes. Sweet-smelling flowers hung from vines on the ceiling, and smooth stone steps led into the steaming water.

The moment they stepped inside, a wicked idea popped into Hyun-woo’s head.

Stheno sensed it immediately. “No, you bastard. Don’t you dare—”

“Cannonball!”

Hyun-woo threw her into the pool first, then jumped in right after with a massive splash.

“AGGGHH!” Stheno came up coughing, having swallowed a mouthful of water. She grabbed the edge of the pool to steady herself.

“What the… cough… fuck is wrong… cough… with you?!” she yelled, but the corners of her mouth were twitching. “You fucking cute bastard.”

Hyun-woo just smiled, treading water and not saying a word.

“Awake now?” he asked as he moved closer to her.

“Fucker, I’m not even tired,” Stheno shot back after coughing out the last of the water.

Instead of replying, Hyun-woo simply picked her up.

“No, don’t—my sisters are waiting—agh!”

Before she could finish complaining, he shoved his cock back inside her in one smooth thrust. Stheno’s serpent tail flicked sharply as the crystal lights in the bath dimmed to a soft, intimate amber glow.

This time, he moved slowly, savoring every inch.

“Aaah… hah… still horny… you bastard,” Stheno moaned, her voice shaky.

“Nope,” Hyun-woo replied with a cheeky grin. “Just wanted to make you late.”

His cock reached all the way to the entrance of her womb with every deep stroke. “Ooohh~” Stheno couldn’t even pretend to care about the time anymore.

Hyun-woo’s hands slid down her back, gripping the spot where warm skin met shimmering golden scales. The contrast felt incredible under his fingers. He started fucking her with slow, sensual rolls of his hips, making the water splash gently around them.

She grabbed his face and kissed him fiercely. Her long forked tongue slid into his mouth, the split tips curling and stroking around his own with hungry skill.

“Fuck…” she groaned against his lips. “That stupid Sex Beast class is ridiculous.”

The hot water made everything feel slicker and more intense. Once Stheno got her bearings, her inner muscles rippled around him as she began riding him harder. Water splashed everywhere with every downward thrust of her hips.

Her heavy breasts bounced right in front of his face. Hyun-woo leaned in and captured one nipple in his mouth, sucking hard while his hands gripped her hips, helping her move faster.

Her thick tail, which had been lying lazily in the water, wrapped tightly around his waist and ass, pulling him even deeper with every roll of her body.

“Harder—Hyun-woo—fuck me like you own me,” she demanded, her voice breaking into a loud moan as her forked tongue lolled out.

He obliged instantly.

Grabbing her by the waist, Hyun-woo stood up in the water, still buried deep inside her.

Stheno’s eyes widened as he spun her around and pressed her front against the smooth stone wall of the bath. He kicked her coils apart and slammed back into her from behind.

The loud, wet slap of skin meeting scales echoed through the steamy room.

“Yes…! Just like that…!” Stheno cried out, her claws scraping against the stone as she pushed back against him desperately.

Hyun-woo fucked her with deep, powerful strokes. One hand reached around to rub her swollen clit while the other tangled gently but firmly in her snake-hair, stroking the sensitive vipers. The dual stimulation was too much.

Her orgasm hit her like a storm. Her pussy clamped down on him like a vise, rippling and milking his cock violently as she screamed his name.

The intensity dragged Hyun-woo over the edge right after her. He buried himself to the hilt and pumped her full again, thick ropes of cum flooding deep into her womb while the hot spring water swirled around them.

They stayed locked together for a long moment, panting heavily, bodies trembling with aftershocks.

Stheno rested her head back against his shoulder, her forked tongue lazily licking along his jaw.

“…We’re never getting clean at this rate,” she murmured, her voice hoarse and satisfied.

Hyun-woo kissed the side of her neck, still buried deep inside her.

“Good,” he whispered. “I’m not done with you yet.”

*******************

After several hours and one very long (and suspiciously slow) “cleaning session,” Hyun-woo and Stheno finally emerged from the steamy bathroom.

Stheno had shifted back to her human legs, but she still walked with a noticeable, satisfied wobble. The golden scales lingering on her hips and thighs glistened with water droplets. She wore nothing but a loose silk robe that kept slipping off one shoulder, barely covering her body.

Hyun-woo had thrown on his pants and the torn white shirt from yesterday. His hair was still damp and messy.

The moment they stepped into the main living area on the middle floor, the delicious smell of cooking food greeted them. Medusa and Euryale were already in the open kitchen.

Both sisters paused and turned to look at them.

Stheno froze mid-step. Hyun-woo scratched the back of his neck awkwardly.

“Morning,” he tried.

Medusa’s emerald eyes slowly scanned Stheno’s messy hair and flushed face, then moved to Hyun-woo’s damp clothes. Her snakes hissed softly in unison.

“…You two took your time,” she said dryly.

Euryale smiled sweetly, though her eyes sparkled with amusement. “We were going to make breakfast. Since you two were so… busy, we thought we’d start lunch without you.”

Stheno’s face turned bright red. She still tried to salvage her pride. “We can help…”

“Okay,” Medusa said cautiously.

“No,” Euryale said at the exact same time.

But nobody listened to her plea.

************

“Move, I’ll do the eggs,” Stheno declared confidently, grabbing a basket of glowing golden eggs.

Medusa raised an eyebrow. “You burn water, sister.”

“I do not!” Stheno snapped back. She cracked an egg into the pan with way too much force. The yolk exploded everywhere. One of her small vipers leaned down from her hair and licked the mess off her cheek.

Hyun-woo, standing beside her, was trying his best to be useful.

Thanks to years of military cooking, he knew how to make simple, high-calorie meals. He found rice, some dried meat, and basic spices, and started making what he proudly called “Survival Porridge”—a thick, hearty, slightly salty mush that was extremely filling.

It looked like gray sludge.

Euryale peered into his pot, her green aura flickering with mild horror. “That… smells very… practical.”

“It’s good for stamina,” Hyun-woo said proudly, stirring the thick mixture. “Keeps you full for twelve hours. We used to eat this before long marches.”

Meanwhile, Stheno had somehow set the eggs on fire.

“How did you even…?!” Medusa stared at the flaming pan in complete disbelief.

“I was trying to make them crispy!” Stheno yelled, waving a spatula like a weapon. In her panic, she accidentally knocked over a jar of glowing honey, which spilled all over the counter.

Hyun-woo tried to help by mixing his gray porridge into the chaos, hoping to turn it into some kind of fancy savory oatmeal. The result was an unholy gray-purple sludge that smelled like smoke and regret.

Medusa pinched the bridge of her nose. Euryale had completely given up and was now leaning against the counter, watching the disaster with growing amusement.

Finally, after Stheno knocked over an entire shelf of spices while trying to put out the flaming eggs, Medusa’s patience ran out.

“Out.”

Both Stheno and Hyun-woo froze.

“What?” Stheno asked.

“Both of you. Out of the kitchen. Now,” Medusa repeated, her voice calm but terrifying. Her emerald snakes were all standing straight up, hissing in unison.

“But we were helping—” Hyun-woo started.

“You were committing war crimes against food,” Euryale said cheerfully, already pushing them toward the doorway with gentle green magic.

Stheno tried to argue, but Medusa simply pointed at the door with a death glare.

A moment later, both Hyun-woo and Stheno found themselves standing outside the kitchen like misbehaving children.

Stheno crossed her arms and pouted. “I wasn’t that bad…”

Hyun-woo looked down at the gray smear still on his shirt from when the porridge had bubbled over. “We were pretty bad.”

From inside the kitchen, they could hear Medusa’s tired sigh and Euryale’s soft laughter as the two competent sisters began salvaging breakfast.

Stheno leaned against Hyun-woo’s side, her tail sneaking out to wrap loosely around his ankle.

“…At least the sex was good,” she muttered.

Hyun-woo laughed and wrapped an arm around her shoulders, pulling her closer. “It was fucking amazing.”

They stood there together, listening to the sounds of actual cooking coming from the kitchen.
