Episode 52. Doubt and Oath 7
Swish.
Something slowly entered Yubin's field of vision as she lay face down.
'......?'
It was a long, slender object. It was pitch black without any gloss, and its tip was shaped beautifully like an inverted heart.
After blinking for a moment, Yubin soon realized what it was.
"Seyeon, is this perhaps..."
"That's right."
Watching Seyeon's Tail sway gently before her eyes, Yubin gulped. Seeing the classic succubus Tail that only appeared in doujinshi in person felt both fascinating and mysterious.
"Can I touch it?"
"Yes. Just don't grab it too hard."
As Seyeon instructed, Yubin carefully reached out her hand and gently grasped the Tail. Instantly, she heard Seyeon exhale with a soft, "Hoo."
The Tail felt somewhat firm yet soft. It had a texture like jelly encased in a hard outer shell.
Somehow addictive, Yubin continued to fondle and caress Seyeon's Tail. Each time she lightly tapped it with her fingers, the Tail would stiffen momentarily before going limp again.
Just as Yubin's hand was about to reach the tip of the Tail.
"Ah."
The Tail swiftly slipped out of her hand in an instant.
Turning her head unconsciously to look at Seyeon, Yubin's eyes widened. Seyeon had her eyes half-closed, biting her lower lip slightly, her face flushed. It was an expression Yubin had never seen before.
"Yubin-ah. Did you do that on purpose... Ah, never mind. It's fine."
"Huh? Uung......"
Tilting her head in confusion, Yubin simply turned her head forward again.
"But Seyeon-ah, you had a Tail all along?"
"Yes, because I'm a succubus."
"I never saw it until now. I thought maybe you didn't have one because you're not a pure succubus but a half-blood."
"Ah, that's... because I inherited a thick bloodline. You're right. I'm an exception; normally, half-bloods don't have one."
"I see......"
Seyeon said while tapping Yubin's Buttocks with her fingers.
Feeling that sensation to the fullest, Yubin pondered deeply.
'It looks really long.'
Seyeon had been sitting behind Yubin the entire time without changing positions. Yet, if the Tail emerging from her lower back reached right before Yubin's eyes, it meant its length was quite substantial.
Then a phrase suddenly came to mind.
"With this length, we can go a bit deeper today."
Yubin sharply inhaled.
Before she knew it, something was stroking around her anus. It definitely wasn't the touch of fingers. It felt soft and slick.
"Seyeon-ah, so, then... are you putting that in? The Tail?"
"Yes."
"How deep...?"
"Well."
Seyeon said while squeezing a generous amount of lube onto her anus.
"Since it wouldn't be fun to go too deep all at once, I plan to take it step by step."
Yubin didn't ask further and simply nodded.
Smiling faintly at Yubin's obedient attitude, Seyeon immediately inserted her index finger with a push.
"Hheek...?!"
Instantly, her sphincter clenched tightly, but it soon relaxed smoothly.
"Seems like one finger isn't enough now? The entrance keeps gaping open."
"Hh, hht, hheuu......"
The anus, which had been plugged with an Anal Plug all day, was spread open perfectly for Conditioning. Covered in sticky lube, the anus looked as appetizing as a pussy dripping with thick love juices.
"Ah, yit...!"
Soon, the middle finger also invaded the anal cavity. The two fingers stirred the Back Pussy wildly, evenly coating the inner rectal wall with the abundant lube inside.
"Hheut, heuk, haheuk......"
Her hands already clenched, gripping the edge of the mat tightly. Thanks to the blunt Anal Plug, Yubin's sphincter had become extremely sensitive, so even just swirling fingers around made her drip pussy Water and feel sticky pleasure.
Shoooook......
"Hit...!"
The moment the two fingers pulled out, Yubin's back arched slightly as she squirted female ejaculate with a Pffft sound.
Seyeon let out a hollow laugh. It wasn't even intended as foreplay. She was just applying lube inside to prevent injury, but seeing Yubin feel it so intensely was both absurd and delightful.
The Tail, wriggling behind Seyeon, moved smoothly and soon overlapped onto the anus.
"Ah......"
The tip of the Tail touched the entrance with a Chup sound, like a light kiss.
"Yubin-ah, don't tense up."
"It's... not too big, right?"
"No. About the size of three fingers to two fingers?"
Ggoouuk, the Tail pried open the sphincter and began slowly pushing inward.
"Eungut, hueup, haeuu......"
Feeling a greater foreign sensation than before, Yubin tightly closed her eyes and gritted her teeth. The scent of sweat wafted from the mat. It already felt like her body was drenched.
'If I can just endure the insertion......'
As she felt last time, this was the most difficult process.
Yubin thought that if she could just endure this invasive moment, she could handle what came later.
But Yubin knew nothing. She didn't know that the anal passage was longer than she thought and contained various Erogenous Zones.
Shook-!
"Hht......"
As the thick part, like a Plug, passed through, the Tail slid in smoothly. As expected, the sphincter clenched once tightly before relaxing.
"Haaa......"
Holding Yubin's Buttocks firmly with both hands, Seyeon exhaled a hot, heated sigh.
"Hheit?! Haet, hik, hueuuuk...!"
Flapping like a fish, the Tail slapped and churned the intestinal wall. The unfamiliar sensation, different from fingers, made Yubin feel as if her brain was being torn apart.
"Hoo, hh......"
Seyeon's breathing grew rough, as if she had just finished running.
As everyone knows, the Tail is the most sensitive part of a succubus's body.
It was incomparable to fingers, especially ones covered with a layer of latex gloves, poking the anus.
Feeling the intensely heated rectal interior, the sticky mucous membrane clinging densely, and the cutely clenching sphincter all through that sensitive Tail, Seyeon couldn't help but get excited.
"Now, hoo, a little deeper......"
"Eung, hhgit, heuk, hooooo......"
The long, rubber hose-like Tail scraped against the intestinal wall as it went deeper. Unlike short fingers, the endless invasion of the long Tail into the secret hole made Yubin helplessly tremble her back and soak her pussy wet.
"Hmm... Maybe here? Or......"
"Hht, haeup, hueu, haeuuk...?"
Even while feeling it, Yubin tilted her head with a puzzled expression. Seyeon's tone, as if searching for something, gave off an ominous vibe.
Swish swish, Seyeon's Tail ruthlessly churned the rectum, poking and caressing every corner of the intestinal wall. Areas deeper than fingers could reach, places never touched before, were being stimulated recklessly without preparation.
Yubin's body was already trembling with pleasure in heat. Her mammary glands filled her areolae with sweet breast milk, and her pink nipples stood erect, dripping sticky juice. Her armpits clenched, sweat droplets falling like wringing a rag, and goosebumps repeatedly rose and faded on her skin. As both their body temperatures rose, the Room became warm and heated.
"Oh, found it."
Amidst this, Seyeon's Tail abruptly stopped at one point.
"Ah."
When threatened, for example, when a gun is aimed at the forehead or a blade touches the neck, the body shows an instinctive reaction.
Just like Yubin now.
Yubin's body instantly stiffened rigidly. Her spine tingled sharply, and cold sweat poured down her forehead. Goosebumps ran from her Buttocks to the crown of her head, and her lips trembled violently.
Her senses sharpened acutely. She could vividly feel even the saliva she gulped down moistening her throat stickily.
Her pitch-black pupils dilated widely, trying to take in more information to find an escape route.
As if a vulnerable and precious vital spot had been directly targeted, her entire body was sending frantic danger signals toward her head.
And this was a sensation Yubin had felt before.
"Yubin-ah."
"U, un...?"
Yubin answered in a voice trembling even more than her body.
"Why do you think I developed your uterus first? Guess."
"Hht, haat......"
Seyeon gently stroked a slightly deeper spot, a bit more raised than other parts, with her Tail. Yubin's toes wriggled helplessly.
"Maybe because your vagina is a bit long, my fingers couldn't reach it."
Still caressing the thick, button-like raised area as if asking to be pressed, Seyeon murmured softly.
Forcio.
There are various methods to stimulate the cervix.
Until now, it was by pressing the abdomen with fingers, but now Seyeon intends to touch the uterus through the rectum.
Naturally, the latter is much more stimulating. Compared to the soft flesh of the abdomen that protects precious organs, the intestinal wall is far too thin and fragile.
It was like secretly invading through the unguarded back hole to attack the blind spot.
And surprise attacks on vital spots are most effective.
Cook.
"Ook?!"
Ssik- ssiiik-!
Without any warning, Seyeon pressed the cutely protruding soft uterus with her Tail, Ggoouk.
Stimulation coming from a much closer place than the abdomen.
Yubin immediately arched her back, splattering sticky pussy Water onto the mat like a fountain. An immense pleasure ruthlessly struck her brain. Her head lifted, her throat tightened, and vulgar moans escaped uncontrollably.
"Haa, haa, hit, heuuuk......"
Even though it was just a single press, the aftermath still enveloped her entire body.
"If I had conditioned your anus first instead of your uterus, it wouldn't have been as fun. Good thing I developed it in advance, right?"
"Ah, aeuuu......"
"Now, one more time."
Ggoouuk-
"Hhyaak...!"
Ssiiik, female ejaculate gushed out helplessly. Just pressing the mucous membrane-raised uterus made her body tremble and climax as if by unconditional reflex. Already obedient like a female dog slave, her uterus accepted the stimulation submissively without resistance, gushing out pleasure hormones in bursts.
"Hheek, hik, euooook......"
Yubin blinked through tears streaming down her face from the relentless onslaught of pleasure.
The reason the stimulation was so intense wasn't just because the intestinal wall was physically thin. There was also a psychological aspect: the humiliation of being conditioned anally while lying face down like a cat perfectly matched Yubin's innate masochistic tendencies.
Amidst this, pressing the uterus, which had already become an Erogenous Zone beyond just sensitive, naturally made her climax uncontrollably.
"Haa, hh......"
Seyeon smiled a smile soaked in bliss and gently covered her face with both hands. Her cheeks felt burning hot. Unbeknownst, Seyeon was also sweating profusely.
Just moving inside the anal cavity provided strong stimulation, and on top of that, Yubin's sphincter kept kneading the Tail......
"Aheuk, hhkuk, heuu, hiiiiik?!"
Pyuut- Pyubyubyt......
Churning the sticky intestinal wall to deliberately create a foreign sensation, then poking the uterus directly.
The pussy hole gaped open, splattering sticky female ejaculate with Pfft, Pfft sounds. The warm pussy Water seemed to steam up, making the floor feel warm.
Yubin's anus had long been broken in since last time. The sticky rectum warmly embraced the Tail, holding it tightly and begging for more pleasure. The uterus, having lost its original function as a baby room, merely trembled helplessly with its cervix exposed. It was a female-like attitude expecting only pleasure.
"Eunghit?! Heueup, hik, aheuuu......"
Her feet flapped, cutely patting the mat. Seyeon had moved and was now sitting demurely beside Yubin. Seyeon's hand crept slowly toward Yubin's lower abdomen.
"Hht, hiik...!"
Tap.
Where Seyeon's finger touched was precisely the Ovaries. Spreading her hand, she fondled both sides with her middle finger and thumb.
Simultaneously, the Tail also stopped, aiming precisely at the cervix.
"Hoo, Yubin-ah. You, really... are such a naughty girl. Having such a lewd body... What if you had been raped by someone else? Huh?"
"Ah, eu, aah......"
"You should consider yourself lucky to be taken by me. There's no one as gentle as me. Understand?"
"Ah, underst, hht, understand......"
Seyeon's voice, filled with joy and happiness, trembled as it echoed through the Room. Her pupils flashed red.
Yubin answered while pulling her knees inward as if frightened.
"Yes, yes, that's right......"
Seyeon stroked Yubin's head while exhaling hot breath. Unlike usual, her hand movements were impatient and rough.
Even while gasping with pleasure, Yubin found that sight fascinating. It was almost like seeing Seyeon sexually excited for the first time.
That made her feel even better. It felt like she had succeeded in serving as a female dog. No, she was indeed a female dog. It was evident that Seyeon was Yubin's owner, and Yubin was merely a female animal who must faithfully serve her owner by scattering pussy Water.
"If you climax from your Ovaries being pressed from the front and your cervix from behind... you'll surely faint. But is that still okay?"
Now that both body and mind were soaked in pleasure, Yubin had no reason to refuse.
"Yes...!"
A smile formed on Seyeon's sweaty face. The corners of her mouth trembled slightly.
Suooook-!
It happened in less than a second. While pressing the uterus with her Tail, Seyeon pulled out, scraping against the heated mucous membrane and prying through the sphincter. A cute Poong sound echoed softly.
Simultaneously, the fingers placed on the lower abdomen dug in deeply, Pouuk, precisely stimulating the Ovaries.
"Ah."
A deathly sigh escaped Yubin's lips.
For the third time now, such a massive climax always has a grace period.
"Eunghoooooook?!"
Pyuut, pyuuut-!
Ssiiik-
Her honest body reacted first to the immense pleasure instead of her dumbfounded brain. As if someone forcibly pulled her hair, Yubin's head snapped back. As usual, her tongue lolled out, and her lips gaped irregularly. Her pussy convulsed wildly, squirting transparent female ejaculate with ssik ssik sounds, and her Back Pussy similarly gushed out sticky lube.
Yubin lost consciousness immediately, but the pleasure forced her body to continue climaxing. Her eyes rolled back as if to faint. Sweat poured from her entire body like rain. A subtle Female Pheromones scent rose from her armpits. Thick breast milk spurted, Byut, byut, from her chest compressed against the floor. The pussy hole scattered female ejaculate incessantly as if urinating. Her fingers flailed, trying to grab onto something for support. It was the body's instinctive reaction, not the brain's.
Since she fainted, the initial short cry was all the moaning. It was a quiet yet tumultuous climax.
Pulling out her Tail suddenly also brought a rush of pleasure to Seyeon, making her tightly close her eyes and let out a shallow voice. It was a sexual sensation she hadn't felt in a long time.
"......eu, hat?! Heuuuuk?!"
"Huh? Yubin-ah, you're awake?"
15 seconds after climaxing.
Suddenly waking up, Yubin let out an unexpected moan due to the lingering climax sensations and climaxed once more.
"Hh, heek, heuk, heeeek......"
"Your stamina has improved. I thought you'd be out for an hour."
Pyuut......
Yubin answered by opening her lower lips instead of her mouth, squirting pussy Water with a Pfft.
