Vacuum Resonance
"Haa... haa..."
The air in the warehouse was heavy and damp. The sweet scent of night-blooming flowers mingled with Eila's thick, musky aroma, clinging to his lungs with every breath. Hans pulled up his pants and staggered. His knee joints creaked as if they might give out.
"Leaving already?" The voice behind him dripped with disappointment. Eila, who had been screaming beneath him moments ago, now clung to his back like a cicada, still wearing her torn stockings.
"Can't we stay like this a little longer? I still want to smell more of your scent, Hans..." She wrapped her arms tightly around his waist and rubbed her face against his back. A chill ran down Hans's spine. He wondered if this was the same woman who had been swinging a leather strap and threatening to kill him just an hour earlier. Now her eyes were half-glazed, shimmering with blind affection for him.
Hans broke into a cold sweat and tried to gently pry her arms off. But Eila's grip was stronger than he expected.
"E-Eila, I really need to go now..."
"Where to?" Eila stepped in front of him and looked up. She moistened a handkerchief with her saliva and began carefully wiping the sweat and saliva from his neck. "Going back to that innkeeper again?"
"No, it's not that..."
"Hmph." Eila snorted and straightened his shirt collar. Her fingers brushed against his collarbone. "I'll let you go. But..." She pressed her lips to his ear and whispered, "Don't give that look to any other woman. Understood?"
"Y-Yes... I'll keep that in mind."
"Good answer. My pretty little puppy." She planted a deep kiss on his cheek. Hans fled the warehouse as if escaping. He could feel Eila's burning gaze boring into his back like a laser.
Once out on the street, Hans's legs gave out and he stumbled. The world spun around him. I'm going to die... I really am going to die. Masa had sucked him dry all night, and Eila had squeezed him dry during the day. It felt like not just his semen but his very soul had been drained.
Passersby glanced at him. Hans looked a mess. His hair was disheveled, his shirt wrinkled, and his body reeked of various women's perfumes and semen. Most telling were the layered kiss marks on his neck, blatantly advertising the intense time he had spent.
"Huh...?"
Just then, he spotted a familiar silver armor in the distance. It was Karen. Hans instinctively tried to duck into an alley, but his legs refused to obey.
"Hans? Perfect timing. I was just looking for you."
Karen spotted him and strode over. "What happened to you? Why do you look like that?"
Up close, Hans's condition was alarming. His eyes were hollow, his lips parched, and his entire body burned like a furnace.
"K-Karen, I'm fine..."
"Fine, my foot! How could this..."
Karen's gaze locked onto the dark bruises on his neck. For a moment, her eyes filled with shock.
"Your blood vessels are on the verge of bursting from channeling mana currents through your body. Hans, don't tell me... you've been pushing yourself this hard in training even on normal days?"
"......Yes?"
Hans stared at her blankly.
"Incredible... truly incredible. To fight such a desperate solitary battle to reach the Master rank... I feel ashamed as a knight."
Karen, overcome with emotion, grabbed Hans's hand tightly. As expected, this woman's brain worked differently from normal people.
"Come, Hans. Follow me for a moment."
"W-Where to..."
"There's someone waiting for your noble teachings."
Karen gripped Hans's wrist with unyielding strength and dragged him away.
[Women's Security Barracks]
Hans's eyes widened.
"K-Karen? This is..."
Karen spoke solemnly. "The female officers are waiting for you."
Hans wanted to scream. Entering this women-only zone in his current state might actually leave him dried up and dead. But Karen's grip was like steel. Hans was dragged inside like a sack of potatoes.
Inside the barracks. A pleasant scent of soap and faint flowers tickled his nose. The air was on a completely different level from the sweaty male dorms.
"Captain! You're here!"
A female officer standing at attention beside a bed gave a loud salute. She had short brown hair, a youthful face with a few freckles, but her eyes burned with fanatic intensity.
"Let me introduce you. This is the Mana Sage I mentioned, Lord Hans."
"Pleased to meet you! I'm new recruit Rina! I've heard so much about you from the captain!"
Rina bowed at a perfect ninety degrees. When she looked up at Hans, she saw his hollow eyes, cracked lips, and tattered clothes. An ordinary person would have called him a wreck, but to Rina, already brainwashed by Karen, it looked different.
That appearance... traces of testing the limits of the body through extreme mana control. How noble...!
Tears welled in Rina's eyes.
"I-I heard too! That you defeated Deputy Leo in a single blow... not with raw power, but through advanced mana refinement!"
"Ah... yes..."
Hans nodded awkwardly. He couldn't believe beating that idiot Leo was being glorified like this.
"I want to learn too! I want to expel all the turbid energy from my body and become stronger! I'll endure any pain if it's your teaching, Sage!"
Rina grabbed Hans's hand with both of hers and cried out. Her palms were soft, without a single callus.
Just then, an urgent messenger's voice came from outside the barracks.
"Captain Karen! The lord has summoned you urgently!"
Karen frowned. "Of all times... Hans, I'm sorry, but start without me. I'll be right back."
"What? Karen? Wait a second..."
Before Hans could grab her, Karen vanished like the wind. Only Hans and Rina remained in the room.
Silence. Rina swallowed hard, then spoke with a determined expression.
"I'm... ready."
But she simply stood at attention, eyes wide open. Hans sensed it immediately. Karen had clearly never explained what "turbid energy expulsion" actually was to Rina. This new recruit had the look of a soldier charging into battle without knowing what fate awaited her.
She really has no idea.
Hans put on a solemn expression and opened his mouth.
"Rina, first... remove your lower garments. Pants and underwear, everything."
"......?! Y-Yes? W-Why the clothes..."
Rina's face flushed crimson in an instant. Even with her lack of knowledge, the instinctive revulsion at exposing her lower body to a complete stranger burst forth. But Hans shamelessly pressed on, using the military discipline Karen had instilled.
"I need to check the expulsion passage directly. Didn't Captain Karen tell you? Feeling ashamed during training is a disgrace to an officer."
"U-Understood!"
At the mention of Karen's name, Rina's eyes changed. With trembling hands, she grabbed her belt buckle. Her eyes grew moist with shame, but she bit her lip and moved her hands as if conducting a weapon inspection.
Swish.
The security uniform pants and white cotton underwear dropped to her ankles in one motion. Her pale thighs and the secret forest between them were exposed to the air. Rina suppressed the urge to sit down and cover herself, standing ramrod straight.
"Now lie on the bed and spread your legs. I need to precisely diagnose the state of the expulsion port."
"......I will carry out the order!"
With an expression that looked ready to cry, Rina lay on the bed and spread her legs wide without a moment's hesitation.
"......!"
Hans's eyes narrowed slightly. It was a demand that would have sent any normal woman fleeing in horror, but Rina instead clenched her fists and tensed her body rigidly. Even as her face showed she wanted to die of embarrassment, her posture was grotesquely disciplined. The combination of her profound ignorance and earnestness, focused solely on the "turbid energy expulsion" training, made Hans's lower body stir heavily.
Between her somewhat thick, untamed brown pubic hair, a fresh pink secret flesh peeked out shyly. It was the freshest one he had seen yet. The taut, unblemished crimson folds brimmed with vitality, as if they might burst at any moment. The tightly closed labia were smooth, and the cute clitoris peeking above them seemed to tremble just from his gaze. There was no fishy smell at all—only the fresh scent of soap, as if she had just bathed, and the sweet, girlish scent of skin that tickled his nose.
Twenty years old... same age as me.
Hans swallowed dryly without realizing it.
"P-Please begin, Sage."
Rina squeezed her eyes shut and spread her legs even wider. Hans approached as if entranced.
Well, since I'm only using my fingers... it won't drain as much stamina.
He raised his index and middle fingers, just as he had with Karen, and brought them to Rina's entrance.
"Pardon me. I'll check the turbid energy..."
"Hnn!"
One finger pushed into the narrow opening.
"Ah, ugh...!"
The hot, wet inner walls clamped down on Hans's finger. When he pushed deeper, his fingertip met the taut hymen. The barrier of untouched purity stretched precariously, as if it might tear from just one finger. Hans carefully twisted his finger without rupturing it. Being her first time, the walls were extremely tight and elastic, desperately writhing as if trying to expel the intruder. Hans skillfully found the G-spot between the narrow gap and began stimulating it. When he curled his finger like a hook and scraped the walls, an erotic moan Rina had never uttered before escaped her lips.
"Haa...! Ah, ahn! This feels strange... the sensation..."
Rina's moans spilled out. Squelch, squelch. Love juices flowed out and wet her entrance. But there was a problem. No matter how much he stimulated her, there was no sign of the fountain-like release like with Karen. Rina's bladder wasn't sensitive, and her vaginal muscles were stronger than Karen's, so simple stimulation couldn't press on the area around her urethra.
Five minutes, ten minutes... When cramps began in Hans's forearm, Rina opened her eyes, on the verge of tears.
"Sage... do I lack talent after all?"
"What?"
"You said my body would be purified transparently... so why is only this ugly, dirty residue coming out of me? Am I... beyond salvation?"
Her eyes were filled with deep disappointment and self-reproach. To her, who had expected clear, transparent mana energy, the fishy, sticky liquid wetting her thighs seemed like proof of how corrupted she was.
Hans stopped his hand and put on a serious expression.
"Hmm... as expected."
He shook his head and withdrew his fingers.
"Rina's turbid energy... is in a different state."
"What do you mean..."
"Captain Karen's was in liquid form, but yours... is clumped together like jelly."
"J-Jelly?"
Rina looked down at her lower body with a frightened expression.
"Is it serious?"
"No. However..."
Hans paused for effect.
"Simple physical impact, meaning fingers, cannot expel it. To forcibly extract the clumped turbid energy... another method is needed."
"What is it! I'll do anything!"
Rina's eyes burned again. Hans cleared his throat and used the most technical terms he could muster.
"We need to use vacuum resonance therapy."
"Vacuum... resonance?"
"Yes. It's an advanced technique that creates a vacuum in the mouth to directly suck out the yin energy."
Hans looked Rina straight in the eyes.
"I have to suck it out directly with my mouth. It may be embarrassing, but please endure it as part of the treatment."
Rina's face turned beet red. Having a man put his mouth on her most private place... but she soon nodded with resolve.
"I'll entrust my body... to you, Sage! Please purify me!"
As expected of a fanatic. She was easy to convince. Hans breathed a sigh of relief inwardly and positioned himself. In truth, he couldn't just pass by that plump, appetizing pussy. Fingers weren't enough to satisfy him. The desire to taste it directly with his tongue dominated him.
"Then, pardon me."
Hans buried his face deep between Rina's legs.
"Kyaa!"
When the hot breath touched her vulva, Rina's hips bucked. Hans didn't rush. First, he flicked the tip of his tongue against her clitoris to warm her up.
"Hnn... hah!"
Then he slowly spread his tongue wide, enveloping her clitoris and labia entirely. Slurp.
"Ah...!"
Now came the real thing. Hans sealed his lips tightly against her entrance, blocking any air. Then he used his lung capacity to suck hard.
"Chuuuuuup-!"
"Hik?!"
Rina's scream burst out. The vulgar knowledge he had picked up from internet communities in his past life was transforming into a useful skill at this moment.
"Ah, no! Something... something's being sucked out! It feels like my soul is being sucked out!"
Rina's hands clawed at the bedsheets. Hans sealed his lips perfectly against her urethral opening. He sucked air from deep in his lungs, creating such strong negative pressure that his cheeks hollowed. Like a pump drawing up thick liquid, he squeezed his cheek muscles even harder to increase internal pressure. Each time, Rina's flesh trapped inside his lips stuck to his palate with a sticky sound and swelled as if about to burst.
Sluuuurp! Chuuuuup!
The explicit sucking sounds echoed through the barracks. Rina's vaginal walls convulsed, and she felt a hot mass rising from deep in her belly.
"Sage! Master! Aaaahn!"
Rina's legs squeezed Hans's head. This was the limit.
"I-It's coming! Uwaaaah!"
Rina's back arched like a bow. In that moment—
Spurt-!
It wasn't clear water like Karen's. Thick, white liquid gushed out like a volcanic eruption, gurgling and spurting.
Glurk! Gulp! Glurk!
Concentrated ejaculate poured into Hans's mouth.
"Mmph...!"
Hans didn't avoid it. He rolled his tongue to catch the sticky, fishy liquid and licked up every last drop. Slightly salty yet sweet, the rich taste of a female.
"Kuh..."
Hans swallowed it with a gulp.
"Haa... haa... haa..."
Rina was convulsing all over, her eyes rolled back. White foam mixed with love juices still flowed from between her legs, soaking the cleft of her buttocks.
A moment later, Rina looked up at Hans with dazed eyes. Life slowly returned to her unfocused pupils. She touched her lower belly with a trembling hand.
"My stomach... feels hot. It feels like a lump of stone has been pulled out..."
Tears welled in her eyes.
"Master..."
Even after gushing enough liquid to soak the bedsheets, Rina remained spread-eagled in ecstasy. Her eyes were glazed, and a thin trail of drool dripped from her lips.
"I've never felt like this before... It feels like my body has been reborn..."
She reached out with a trembling hand and grabbed Hans's pant leg. Even though she looked like she didn't have the strength to lift a finger, her gaze toward Hans held a more dangerous fanaticism than Karen's.
"Every day... you'll do it every day, right? I still feel like there's turbid energy left. Next time... suck it deeper, please."
Hans felt a chill run down his spine at Rina's blind gaze.
I'm screwed.
One Karen was already overwhelming, and now another, even more dangerous fanatic had been added. Hans wanted to collapse as his legs gave out, but Rina was already staring at him with expectant, unfocused eyes, anticipating the next treatment.
