Late at night, I headed to Jang Seo-yeong's quarters. The meeting with the surrounding sects had gone on until quite late.
I stood before her door and knocked quietly. There were no servants to be seen nearby.
"…Come in."
When I entered the room, Jang Seo-yeong was sitting beneath the soft lamplight. She was still wearing the same clothes as during the day.
She probably hadn't been able to rest properly all day because of her anxiety and worry. Her pale face looked even whiter beneath the lamplight.
"You're late…."
Her voice trembled. Her usual cold tone had vanished, leaving only anxiety behind.
"The meeting ran long."
Before I could finish speaking, she asked,
"Is it really true… that my inner power will increase…?"
Her gaze was pitiful, as though she were clinging to her last hope. But seeing her like that only turned me on even more.
“Yes. Are you having doubts?"
I slowly approached her. Jang Seo-yeong's shoulders flinched, but she did not run away.
"I don't know… whether you truly mean to help me…."
Her voice trembled. Anxiety, suspicion, and maternal affection for her child were all mixed in her eyes.
"You can confirm it yourself, Mother."
My hand wrapped around her shoulder. The warmth coming through her silk clothes was hot.
"Shall I begin?"
She slowly nodded.
"Do it…"
Her words trailed off. My hand slipped between her clothes, and my fingertips touched her soft flesh.
Jang Seo-yeong collapsed onto the bed.
My hand slipped beneath her silk clothes. Her H-cup breasts spread out to either side.
"Haaah…"
When I grabbed her slightly sagging, enormous breasts, a moan escaped her lips.
I gently scratched her nipples with my palm and felt them harden. Her face reddened with shame.
"Your body is honest, Mother."
My fingers slipped inside her panties. The silk underwear was already soaking wet when my fingers touched it.
-Squish, squish!
"It's noisy… Ahh!"
When my fingers stroked her pussy, her back arched.
-Squelch, squelch!
The sound of my fingers moving inside her underwear echoed through the room.
"Stop… Ahh! Hurry…"
Jang Seo-yeong let out a plaintive moan.
"Your pussy is clenching around my fingers and won't let go."
"I said hurry… ngh!"
When I lightly touched her clitoris with my finger, her back arched high. Her juices flowed down between her silk panties.
"Shall we really begin now?"
After stripping her, I placed my cock against the entrance to her pussy. Her vaginal opening twitched in response.
I rubbed my cock against her pussy while watching her expression. She stared down at it with lust-filled eyes, breathing roughly. Contrary to her words of refusal, the corners of her lips were subtly raised.
"Kngh…"
When I slowly pushed it inside, her hot inner walls wrapped around my cock. Tears gathered at the corners of Jang Seo-yeong's eyes.
"Hiiit, this is… Ahh. Too… Haaah!"
Her H-cup breasts jiggled. A sweet moan escaped her lips.
"Ahh… this is…"
Jang Seo-yeong's vaginal opening clamped around my cock. Her hot inner walls squeezed and writhed around it.
"Mother, if you clench like this…"
The grip was incredible from the very beginning. Each of her vaginal folds writhed as though they were alive.
-Thrust!
When I pushed it a little deeper, a moan burst from her lips.
"Haaah! It's too… big…"
"It isn't even halfway in yet."
Her eyes widened at my words. My huge cock pushed straight against her cervix.
"Kngh… like this… haa!"
I grabbed one of her breasts with one hand. I could feel her nipple hardening beneath my palm.
-Squelch! Squelch!
Juices overflowed each time I slowly moved my hips. Her pussy clamped down tightly, as though it did not want to let go of my cock.
"To think you've been hiding such a lewd body all this time…"
"…Ahh! There… no…"
Each time I thrust against her cervix, her back arched like a bow. Seeing the once-haughty Jang Seo-yeong moaning beneath me was even more stimulating.
"Haaah… haa… I'm getting strange…"
Jang Seo-yeong's gaze gradually grew hazy. The sight of her melting into pleasure was obscene.
My hand tightly gripped and twisted her nipple.
"Hiiik!"
A moan mixed with pain and pleasure burst from her lips. Yet her pussy clamped down even more fiercely.
"It seems you're enjoying this too, Mother."
"That's… Ahh! A lie… This is…"
Contrary to her denial, her hips began moving to the rhythm. It was as though she wanted to take my cock even deeper.
"Shall we pick up the pace now?"
"No… haa!"
When I moved my hips faster, her moans grew louder.
-Thud, thud, thud!
"Aah! Haaah!"
I could see Jang Seo-yeong's reason gradually crumbling.
-Thud! Thud! Thud!
The sound of our bodies colliding echoed through the room.
"Mmph! Haa… nooo!"
Each time I moved my hips quickly, Jang Seo-yeong's breasts bounced wildly. I twisted her nipples and drove my cock even deeper.
"Your pussy is clinging to my cock and doesn't want to let go."
"Don't… say… that… Ahh!"
She trailed off with a moan. Her vaginal walls clamped around my cock even more tightly.
-Squelch! Squelch!
“Haaah! Ah, no…! Ngh…!”
When I thrust hard against her cervix, her back arched high. Juices spurted from her heated pussy.
“Mother. Which do you prefer, my father's cock or mine?”
"Th-that… ngh, haa!“
“Answer me properly. Which cock do you prefer?”
I continued questioning Jang Seo-yeong, who was reluctant to answer. My hips never stopped moving.
“Aah…."
Jang Seo-yeong's lips parted slightly, and a breathless sigh escaped.
“…Ahh, I prefer your cock… ngh…."
She blushed as she answered. At the same time, her hips moved as though trying to take my cock even deeper.
The coldness from before had vanished, replaced by the expression of a lustful female hungry for pleasure.
“Heh heh. Since you gave me the answer I wanted, I'll reward you by thrusting even harder.”
-Thud! Thud! Thud!
"Haaah! I'm coming… ngh!"
Jang Seo-yeong's pussy contracted violently. She climaxed while clamping around my cock. But I did not stop.
"It isn't over yet, Mother."
"No… haaang! I'm sensitive right now…"
Ignoring her plea, I pushed my cock even deeper. Her H-cup breasts bounced violently.
"Haaah! Haa! It's coming… I'm coming again!"
Her pupils grew unfocused after the successive climaxes. Beneath the lamplight, her face twisted with pleasure.
“Mother! I'm going to come! I'll fill your womb with semen!”
"Inside… haa, ah, no…! Don't come inside… ngh…, aahaaang!"
Yet her pussy clamped around my cock even more tightly. Her womb writhed as though craving my semen.
"Kngh…"
Hot semen filled her womb.
"Haa, haaah!"
Jang Seo-yeong's entire body trembled violently. Her pussy contracted as though determined not to let a single drop of semen escape.
While her body trembled in the afterglow, I activated the Daoist Yin-Yang Manual. Inner power flowed into her body.
Our vital energies mingled and began to circulate.
"Nghhh!"
Jang Seo-yeong's eyes opened wide. She seemed startled by the sensation she was experiencing for the first time.
"Wh-what is this… Ahh! Aah!"
She could feel her own inner power changing as well. A powerful sensation, different from the pleasure of sex and coming from somewhere deeper, overwhelmed her.
“Ah…. Aah…. Haaahaaang!!!"
Her pussy contracted even more violently, squeezing my cock.
Hot energy flowed through her entire body. As our vital energies mingled through the Daoist Yin-Yang Manual, I felt new strength accumulating in my dantian.
Jang Seo-yeong seemed to be feeling the same sensation. Her eyes wavered.
"This is… truly…"
After directly feeling her inner power increase, her attitude changed. The suspicion she had held at first disappeared, replaced by a gaze that seemed to want more.
"Haa… more… I need more…"
Her pussy clamped around my cock once more. She seemed to be moving instinctively to absorb my vital energy.
'The effect is greater than I expected.'
The increase in inner power from our Yin-Yang union was beyond anything I had imagined.
"Hngh…"
Jang Seo-yeong panted and lifted her hips. A pleasure entirely different from the sex I had experienced with Seol-hee spread throughout her body.
"Ahh… this is strange… my body…"
Her pussy writhed as it wrapped around my cock. Her reactions grew even more sensitive. Her vaginal walls moved like a living creature as they squeezed my cock.
Before my eyes, Jang Seo-yeong's lovely red lips glistened.
I kissed her on the mouth.
"Hngh… slurp…"
Saliva dripped as our kiss continued. As our tongues intertwined, her pussy clamped even more tightly around my cock.
-Squelch! Squelch! Squelch!
"Hngh… ahh, aah… ah, haa!"
Each time I slowly moved my hips, her vaginal walls squeezed my cock.
I grabbed one of her enormous breasts with one hand and twisted her nipple.
"Aah! Not… so hard…“
"Can you feel your pussy twitching, Mother? Even now, it's desperately twitching, begging for semen."
"Don't… say that… haa!"
Each time I thrust deeply against her cervix, her back arched like a bow.
"Hngh… slurp…"
Saliva dripped as our kiss continued. As our tongues intertwined, her arms naturally wrapped around my neck.
Before I knew it, she had become lost in our kiss. She actively entwined her tongue with mine and exchanged saliva.
"Hngh… haa…"
When our lips parted, a silver thread snapped. Her gaze grew darker with ever-deepening desire.
Her pussy was still clamped tightly around my cock. Her vaginal walls writhed, trying to take it even deeper.
-Squelch, squelch!
"Mother, can you hear it? That vulgar sound coming from your pussy."
"Stop… talking… Ahh! Aah!"
Though her face reddened with shame, her grip tightened. She pulled me closer by the neck and demanded another kiss.
"Slurp, smack…! Aah…!"
With a sweet moan, her legs wrapped around my waist. Her ankles pressed against my back as though asking me to thrust deeper.
-Thud! Thud! Thud!
"I'm coming! Ahh! Harder!"
Her usual haughty appearance had vanished completely, leaving only a female who craved nothing but pleasure. Her breasts clung to my upper body, their shape crushed against it.
"Mother… I'm going to come inside."
"Inside! Come inside me! Haaah!"
I thrust deeply against her cervix and poured my semen inside. Her pussy contracted and greedily sucked it in.
Jang Seo-yeong's entire body trembled violently. Her fingernails scratched my back. Her body convulsed as we reached the climax of our Yin-Yang union.
"Oooooooh!"
At the moment of climax, our vital energies mingled, and intense pleasure swept through our entire bodies.
After a while, Jang Seo-yeong slowly opened her eyes as she caught her breath. Her gaze had changed.
"Do you believe me now?"
Instead of an answer, I received a hot kiss.
