Chapter 23: Daoist Yin-Yang Manual (19)
Late that night, I made my way to Jang Seo-young's quarters. Meetings with the neighboring sects had dragged on all day, making it very late.
Standing before her door, I knocked quietly. There were no servants in sight.
"...Come in."
As I entered the room, Jang Seo-young was sitting under the soft glow of a lantern. She was still in the same clothes she had worn during the day.
She must have been too consumed by anxiety and worry to rest properly all day. Her pale face shone even whiter in the lamplight.
"You're late..."
Her voice trembled. Her usual cold tone was gone, replaced by pure anxiety.
"The meeting ran long."
Before I could even finish, she asked.
"It's true, isn't it...? That my internal energy will rise...?"
Her gaze was pitiful, as if she were grasping at her last hope. But that very sight turned me on even more.
"Yes. Do you doubt it?"
I slowly approached her. Jang Seo-young's shoulders flinched, but she didn't run.
"I... I don't know... if you truly mean to help me..."
Her voice trembled. Her eyes were a mixture of anxiety, suspicion, and the maternal love she held for her child.
"You can confirm it for yourself, Mother."
My hand wrapped around her shoulder. Her body heat was intense through the silk of her clothes.
"Shall we begin?"
She slowly nodded.
"Do it..."
Her words trailed off. My hand slipped inside her clothes, my fingertips brushing against her soft skin.
Jang Seo-young fell back onto the bed.
My hand delved beneath her silk clothes. Her full, H-cup breasts spread to either side.
"Haaaah..."
When I squeezed her huge, slightly sagging breasts, a moan escaped her lips.
I gently scraped her nipple with my palm and felt it harden. Her face flushed with shame.
"Your body is honest, Mother."
My fingers slipped into her underwear. The silk was already soaked through.
Squish, squish!
"Stop that noise... Hah!"
As my fingers caressed her cunt, her back arched.
Squelch, squish!
The sound of my fingers churning inside her underwear echoed in the room.
"Stop... Hah! Quickly..."
Jang Seo-young let out a sorrowful moan.
"Your cunt is biting my fingers and won't let go, Mother."
"I told you to hurry up... Heuk!"
When I lightly brushed her clitoris with my finger, her hips shot up. Her juices trickled from her silk underwear.
"Now, shall we really begin?"
After stripping her clothes, I pressed my cock to the entrance of her cunt. Her vaginal opening twitched in response.
I rubbed my cock against her cunt, watching her expression. Her eyes were filled with lust as she panted, staring down at it. Despite her protests, the corners of her mouth were slightly turned up.

"Keuk..."
As I slowly pushed in, hot walls of flesh enveloped my cock. Tears welled in Jang Seo-young's eyes.
"Hiit, this is... Hah. Too... Haaaaang!"
Her H-cup breasts swayed. A sweet moan escaped her lips.
"Hah... This is..."
Jang Seo-young's cunt clenched around my cock. The hot walls of flesh tightened and twitched.
"Mother, if you squeeze this tight..."
She was incredibly tight from the start. Every fold of her vagina twitched as if it were alive.
Thrust.
When I pushed a little deeper, a moan burst from her lips.
"Haaaang! It's too... big..."
"I'm not even halfway in yet."
Her eyes widened at my words. In one motion, my massive cock pushed up against her cervix.
"Keuk... Like this... Haat!"
I grabbed one of her breasts with my hand. I could feel her nipple hardening beneath my palm.
Squish! Squish!
Her juices overflowed with every slow movement of my hips. Her cunt tightened firmly, as if trying not to let my cock go.
"To think you've been hiding such a lewd body all this time..."
"...Hah! There... don't..."
Her back arched like a bow every time I prodded her cervix. The sight of the once-haughty Jang Seo-young moaning beneath me was even more stimulating.
"Haak... Haat... I'm feeling strange..."
Jang Seo-young's gaze grew hazy. The sight of her melting into pleasure was obscene.
My hand squeezed her nipple tightly and twisted.
"Heek!"
A moan mixed with pain and pleasure burst out. But her cunt only tightened more fiercely.
"It seems you're enjoying this too, Mother?"
"That's... Hah! A lie... This is..."
Contrary to her denial, her hips began to move in rhythm. It was a movement that seemed to want to take my cock deeper.
"Shall we start picking up the pace?"
"No... Haat!"
As I moved my hips faster, her moans grew louder.
Thwack, thwack, thwack.
"Aaang! Haak!"
I could see Jang Seo-young's reason slowly crumbling.
Thwack! Thwack! Thwack!
The sound of our bodies colliding echoed from the bed.
"Huuup! Haat... Nooo!"
Jang Seo-young's breasts bounced wildly with every rapid thrust. I twisted her nipple as I drove my cock even deeper.
"Your cunt is biting my cock, trying not to let go, Mother."
"Don't... say... that... Hah!"
Her words trailed off into a moan. Her vaginal walls squeezed my cock even tighter.
Squelch! Squelch!
"Haaahk! Ah, no...! Nngh...!"
As I slammed into her cervix, her back arched sharply. Her juices gushed from her heated cunt.
"Mother. My father's cock or mine, which do you like better?"
"Th-that's... Heuk, haat!"
"Answer me properly. Whose cock is better?"
I kept questioning the reluctant Jang Seo-young. My hips never stopped moving.
"Aeuung…."
Jang Seo-young's lips parted slightly, releasing an excited breath.
"…Hnngh, your cock is better... Hnngh...."
She blushed as she answered. At the same time, her hips moved to take my cock even deeper.
Her initial cold demeanor had vanished, replaced by the expression of a female animal craving pleasure.
"Keke. Since you gave me an answer I like, I'll reward you by fucking you even harder."
Thwack! Thwack! Thwack!
"Haa! I'm coming... Huuuk!"
Jang Seo-young's cunt contracted violently. She climaxed with my cock still inside her, but I didn't stop.
"It's not over yet, Mother."
"No... Haaang! I'm sensitive right now..."
I ignored her pleas and pushed my cock in deeper. Her H-cup breasts swayed violently.
"Haak! Haat! Again... I'm coming again!"
Her eyes went unfocused from the successive orgasms. In the lamplight, her face was contorted with pleasure.
"Mother! I'm coming! I'm going to fill your womb with my cum!"
"Inside... Haat, ah, no...! Don't cum inside... Heuk... Aaaaaang!"
But her cunt only squeezed my cock tighter. Her womb twitched as if craving my cum.
"Keuk..."
Hot cum filled her womb.
"Haat, huaaaang!"

Jang Seo-young's whole body trembled violently. Her cunt contracted, as if trying not to let a single drop of cum escape.
As her body trembled in the afterglow of her orgasm, I activated the Yin-Yang Manual. My internal energy flowed into her body.
Our vital energies began to mix and circulate.
"Uuuuk!"
Jang Seo-young's eyes flew open. She seemed startled by the new sensation.
"Th... This is... Aak! Ang!"
She, too, could feel her internal energy changing. A powerful sensation, different from sexual pleasure, washed over her from a deeper place.
"Ah…. Aah…. Hyaaaaaaaang!!!"
Her cunt contracted even more fiercely, squeezing my cock.
A hot energy flowed through my entire body. As our vital energies mixed through the Yin-Yang Manual, I could feel a new power gathering in my dantian.
Jang Seo-young seemed to be feeling the same sensation. Her pupils trembled.
"This is... really..."
Feeling her internal energy rise firsthand, her attitude changed. Her initial suspicion was gone, replaced by a look that seemed to want more.
"Haa... More... I need more..."
Her cunt squeezed my cock once again. It seemed to be an instinctive movement to absorb more vital energy.
'The effect is greater than I thought.'
The increase in internal energy I could feel from the Yin-Yang Union was beyond imagination.
"Hnngh..."
Jang Seo-young panted, bucking her hips. A pleasure completely different from my experience with Seol-hee spread throughout my body.
"Hah... It's strange... my body..."
Her cunt pulsed around my cock. Her reactions were more sensitive, too. Her vaginal walls moved as if they were a living creature, squeezing me.
Below me, Jang Seo-young's luscious red lips glistened.
I kissed her.
"Haa-eup... Chureup..."
Saliva dribbled down as the kiss continued. As our tongues intertwined, her cunt gripped my cock even tighter.
Squish! Squish! Squish!
"Hnngh... Aht, aah... ah, haat!"
Her vaginal walls squeezed my cock with every slow thrust.
I grabbed one of her massive breasts and twisted the nipple.
"Aaang! Not so... hard..."
"Can you feel your cunt twitching, Mother? It's desperately pulsing right now, begging for more cum."
"Don't... say... Haak!"
Her back arched like a bow every time I thrust deep against her cervix.
"Haa-eup... Chureup..."
Saliva dribbled down as the kiss continued. As our tongues intertwined, her arms naturally wrapped around the nape of my neck.
Before I knew it, she was lost in our kiss, actively tangling her tongue with mine and exchanging saliva.
"Hnng... Haat..."
When we broke the kiss, a silvery thread of saliva snapped. Her eyes were becoming stained with an even deeper desire.
Her cunt was still gripping my cock tightly. Her vaginal walls pulsed, trying to take me in even deeper.
Squelch, squelch.
"Can you hear that, Mother? That vulgar sound coming from your cunt."
"Stop... talking... Aak! Ang!"
Though she blushed with shame, her grip tightened. She pulled my neck closer, demanding another kiss.
"Chureup, jjo-op...! Aaang...!"
With a sweet moan, her legs wrapped around my waist. Her ankles pressed into my back, as if telling me to pound her deeper.
Thwack! Thwack! Thwack!
"I'm coming! Haat! Harder!"
Her usual haughty demeanor was completely gone, and she had transformed into a female animal seeking only pleasure. Her breasts were crushed against my chest, their shape distorting.
"Mother... I'm going to cum inside."
"Inside! Cum inside me! Haak!"
I thrust deep against her cervix and poured my cum into her. Her cunt contracted, greedily sucking it in.
Jang Seo-young's whole body trembled violently. Her nails scratched my back. Her body convulsed from the climax of the Yin-Yang Union.
"Ooooooorg!"
At the moment of climax, our vital energies mixed, and an intense pleasure washed over our entire bodies.
A moment later, Jang Seo-young caught her breath and slowly opened her eyes. Her gaze had changed.
"Now... do you believe me?"
Instead of an answer, she gave me a passionate kiss.
