Episode 58. Doubt and Oath 13
Episode 58. Doubt and Oath 13
The tip of the tail touches my center with a gentle poke as if kissing it, just like last time, then begins to pry open and widen the hole, slowly pushing inward.
It was another moment so intense that sweat poured down in streams, but my back pussy, already spread wide open more for receiving than expelling, gulped down Seyeon's tail in one swift motion.
"Hngk...!"
The sensation of foreign intrusion washed over me again.
As the thicker part entered, my sphincter instantly tightened, adorably clamping down on the main body of the tail.
"Haa, haa......"
My already soaked pussy now dripped, drip, drip, with love juice.
"Last time we went all the way to climax with Forcio, so today let's go a bit deeper......"
Schllluuuck......
"Hahng, hht, hnguuuk...!"
The black tail made a lewd, squelching sound as it slid deep inside, schluuuck.
"Ngh, th-there......"
Seyeon's tail suddenly stopped, gently caressing a certain spot that bulged softly upward on the mucous membrane.
That alone made me remember—no, my body remembered—how last time my uterus was pressed poke, poke, making me spray sticky pussy water like a flood in a vulgar climax. It wasn't me, but my body that remembered.
Trickle, trickle......
My body, already conditioned to climax from Forcio, went into heat just from the memory, disgracefully leaking thick love juice.
The sound of thick liquid, plop, plop, hitting the mat was heard, and the female animal scent already began to rise thickly, making my head start to spin.
"Pfft, ah, it's really hilarious. A pretty girl like Yubin, stiffening up and trembling just from being touched there....."
"Ngh, y-you, hik, made me like this......"
The tail precariously touched and stroked the thickly risen uterus, giving just enough pleasure to feel it but not enough to push me over the edge.
It was a dizzying sensation, like looking down from a dizzying cliff.
My hair stood on end, and my body, just as Seyeon said, remained rigid, trembling parpar. Just like when you're so scared your legs shake and you lose control, urine-like love juice weakly trickled, trickle trickle, from my pussy.
"Well, today's goal isn't here anyway."
Saying that, Seyeon's tail slowly withdrew from my uterus.
"Hooooo......"
Only then did my frozen muscles loosen sarr, and the air that had filled my lungs rushed out all at once.
'Thank goodness.'
Going to the uterus through the rectum felt unbelievably good, almost to the point of death, but it also felt somewhat frightening.
'But every time I feel relieved like this, I always end up regretting it.'
Surely not today too?
"Hik...!"
Instantly, the tail was shoved back in with a schluuuck.
Fwoosh, fyoooot-
The sensation of the foreign object, much larger than when it first entered, made the nape of my neck tremble parpar. My intestinal wall, sensitized and inflamed from the earlier Forcio stimulation, wrapped affectionately around the tail, begging for pleasure as usual. As if responding to that expectation, the tip of the tail ticklingly scratched the sticky mucous membrane, wildly stimulating hidden weak points and erogenous zones.
Squish, squiiish-
Under such merciless stimulation, I could only spread my pussy hole wide open and helplessly release female ejaculate.
Seyeon too was now exhaling hot breaths, covering her own face with both hands.
The tail kept coming in without stopping. To the point where I wondered just how deep it was going.
"Ah, is this it?"
The tail, which had been wriggling busily exploring my rectum, poked against something somewhere and stopped right there.
"Hng...?"
Even though it had reached the place Seyeon wanted, I didn't feel anything special.
My uterus would make me feel it, tears dripping, just from being touched.
"Wh-where did it reach, Seyeon-ah...?"
"The colon. Specifically, the Sigmoid Colon. You know it too, right Yubin? The bending part."
I think I know. A diagram of the large intestine I'd seen once floated vaguely in my mind.
Schk, swek......
"How does it feel?"
"Ngh, just, a, a little weird."
Seyeon continued to caress the area around the so-called colon.
It felt subtle, like someone was pressing firmly on the small of my back with their fingertips.
"Hng, hht......"
"Hmm, is it still too tight?"
Seyeon continued rubbing and massaging the colon, muttering like that.
"Yubin's back pussy is surprisingly proud. It'll be conquered quickly once we condition it anyway......"
"Ngh......"
"If it won't let me in... I have no choice but to coax it gently."
'Coax it?'
Not understanding what she meant, I could only tilt my head in confusion.
And then, a short while later.
"Hhheeeek?! Hngk, hit, heguuuuk...!"
I came to understand the meaning of "coaxing" not with my head, but with my body.
Unlike the light poking, poking from before, Seyeon moved her tail wildly, violently pressing ggung, ggung on my colon, attacking without rest.
"Hyaaaaauuuk...! Hngk, heeeeeeek?!"
A sensation of a foreign object, incomparably larger than when she pierced my sphincter, made my whole body tremble burrur.
The tail kept stabbing at the entrance of the colon, trying to force it open, and each time the colon tightened even more, trying to push the tail out. It was as if it was saying this was a place that really shouldn't be entered.
The process of switching between the feeling of intrusion and liberation repeated infinitely, melting my brain with a pleasure so intense it was almost mind-shattering.
"Hhheeee... haang, hht, heheuu......"
Unable to even make a proper moan, I just let out an idiotic smile, my tongue lolling out. Making a vulgar expression a pretty girl like me shouldn't make, I could only helplessly receive the pleasure.
Sticky, gel-like saliva dripped, drip, drip from the tip of my tongue, and sweat and love juice madly soaked my body and the mat as if competing to see which could gush out more.
From all over my body, especially from folded areas like my armpits and thighs, a sweet scent and the smell of sweat mixed into a lewd, erotic fragrance that spread throughout the room.
"Ah, it's starting to open."
"Ugk, ksp, hhit, hnggguk......"
Just as Seyeon said, the colon, which had been coyly pushing away the tail's touch, made a lewd tzkkereok sound and gradually revealed its inner flesh. Succumbing more and more to the pleasure of the intestinal wall being scratched and numerous delicate erogenous zones being stimulated, it began to allow the foreign object's invasion.
The soft mucous membrane clung stickily to the smooth tail, peeling away with a heartbreaking chjook, as if kissing. The more it did, the more the rushing pleasure forced the colon open, revealing weaknesses that should never be shown to anyone.
"Yubin-ah, lift your buttocks higher."
Smack-!
"Hhik?! U, uung......"
Seyeon immediately slapped my buttocks with her palm. I, whose buttocks had sunk down without me realizing, had ended up in a fully prone position. As if bowing to someone.
The sudden wave of burning sensation made me hurriedly lift my buttocks up.
Fyoo-byt, fyoo-ooot-
Spurting out a volume of love juice that would have caused dehydration if not for the Potion, I was helplessly feeling good in that moment.
"Hoo, that's it now."
Even in my dazed state, Seyeon's voice came through clearly. I could feel her heated breath on my buttocks.
That's it meant, right now......
"Seyeon-ah, w-wait a second. If you really put that in-"
Schlook.
Instantly, my body froze. The tail, which had only been attacking the entrance, literally went schlook and went completely inside the colon.
"Eh......?"
Fyoosh-
Squish, squiiiiish......
While I was bewildered, my body just reacted on its own. Trembling parpar, my skin helplessly trickled out pussy water.
"Wow, this reaction is kinda new? Yubin-ah?"
Saying that, Seyeon moved her tail.
"Eh? Ngh. Hik? Uhet, hht, haat...?"
Fyoot, fyoo-byoo-byt-
The tail moved back and forth, instantly traversing the already hypersensitive outside and the inside that had never accepted anything before. Constantly scratching the colon caught in between.
'What...?'
It's weird.
It's a sensation I've never felt before, so I don't know how to describe it......
"Hhik?! Hht. Et, h, oook...?"
While I was confused, every time the tail went in and out of my colon, love juice squirted squish squish from my pussy hole. As if a climax button had been pressed.
My mind didn't even understand what was happening, but my body was feeling it all on its own.
"Hht, haaa......"
Moving my pupils to glance at her, I saw Seyeon with her fists clenched on her knees, her face flushed red, her body trembling parpar in ecstasy.
Fyoosh, fyoo-shoosh-!
With a question mark over my head, I kept going, not understanding a thing.
Finally, after the continuously moving tail went deep inside the colon one more time.
"Hhgiiiiiek...!"
I could finally let out a proper moan and fully feel the sensation of reaching climax.
Trickle, trickle......
"Heuk, hik, hngu, hehe......"
And then... of course, I passed out.
♡♥♡♥♡♥♡♥♡♥♡♥♡♥
"Ugehk......"
I was diligently wiping my body, sticky like malt syrup from sweat and love juice, while lube kept gushing out, ulk ulk, from my anus.
Needless to say, it was unpleasant. Kind of like the feeling during a period?
Plus, because Seyeon had put in a ridiculous amount of gel to "develop" my colon... I had to let the gel drain out of my back pussy the entire time I was showering.
After putting on my freshly laundered clothes and arriving back at the room, I saw Seyeon. Her tail was gradually retracting into her lower back and disappearing.
'Tail......'
It seemed to be one of Seyeon's few weaknesses. I'd seen before how her breathing got rough just from it being touched.
'Maybe if I target that tail, I can turn the tables-'
I immediately shook my head side to side. It was a blasphemous thought.
Seyeon was staring at me blankly as if wondering what I was doing, so I immediately ran to her and hugged her.
Seyeon lovingly stroked me, then grabbed my hair, made me lift my head, and immediately kissed me.
"Hueup, chuu, jjooook, haau, chuu......"
"Jjok, tzeueup, ueup, tchap, hik......"
It was a deep, sticky kiss, like a farewell greeting, while we gazed intently into each other's eyes. As usual, I stayed still while Seyeon rummaged through my mouth as she pleased, savoring it to her heart's content. Our bright red tongues tangled, and sticky saliva, whose it was I didn't know, went down my throat, gulp, gulp.
If we do it too long, this lewd maso pervert body of mine will go into heat, so we keep the last one short, about a minute.
Chjook, Seyeon pulled her lips away and looked at me with eyes sparkling a clear blood-red, smiling.
Feeling somewhat embarrassed, a silly laugh escaped me too.
"Yubin-ah."
"Hng?"
"Take this."
What Seyeon, her lips still shiny with moisture, handed over was......
"A plug?"
"I think you can handle a slightly bigger one now."
It looked similar to the anal plug I was wearing, but the one in my hand now was made of a soft, silicone-like material.
And... it had bumpy protrusions sticking out all over it.
I unconsciously gulped. If I thought about those bumps entering my back pussy and scraping against my sphincter and intestinal wall......
"Ngh......"
My knees wobbled, and I almost collapsed before steadying myself again.
"I can use this starting tomorrow?"
Seyeon nodded silently.
After that, as usual, Seyeon came out to see me off to the school gate.
"See you tomorrow."
"Hng."
'Ah, right.'
I stopped walking and turned to look back at Seyeon.
"You were cute today, Seyeon-ah."
Hearing my words, Seyeon tilted her head as if she didn't understand, then suddenly her face turned bright red as if it would burst, and she turned around first and headed back to the dormitory.
