The Hikikomori's Insatiable Rear
Park Seoyun looked up at me with trembling eyes, her voice soft and uncertain.
“Y-you can just… put it in my asshole whenever you want, right? Even without Seoyun’s permission…?”
“Why, why are you being like this all of a sudden…? It’s obvious… Seoyun’s shit— I mean, my anus is yours… If you want to put it in, just put it in… right? Did Seoyun… um… get something wrong?”
“Haa…” My cock twitched violently. I couldn’t hold back any longer.
“No, you know it perfectly. Noona’s asshole is my personal onahole.”
“It’s not a shit hole…!”
During our brief exchange, Park Seoyun’s chest suddenly swelled outward.
“Hu, ha, hu… Huuu…”
Her breathing accelerated sharply. Even though I hadn’t touched her pussy, thick fluids spurted out in heavy gushes. Beneath her twitching cunt, long, thick strands of silvery nectar stretched downward, breaking and reforming again and again. It was an incredibly arousing, obscene sight.
“Hu, ha, hu, haa… Why, why… um…?”
Even Park Seoyun seemed flustered by the sudden changes in her body. The aphrodisiac was absorbing far faster than I’d expected. Ah, right. It’s because it’s her intestines. The intestines were an organ with tremendous absorption power. The item’s description had already noted its rapid absorption rate, but injecting it directly into her bowels had sent the effects skyrocketing.
“Hu, haa, huu, haa…! U-uh, J-Junyoung… Junyoung-ah…”
Unable to form proper words, Park Seoyun simply wiggled her massive ass according to pure instinct.
“W-what should I do… Junyoung… My p-pussy and… my anus, they’re… they’re so itchy, so restless… I can’t stay still… They keep twitching… What do I doooo…!”
For a moment, I simply stared at her holes in a daze.
Wow… fuck… this is insanely hot…
Her asshole and pussy were opening and closing at the exact same rhythm. Both holes drooled with love juices and thick gel, looking just like Seoyun’s mouth when she drooled during orgasm. I slapped her moon-like ass cheek with my palm.
Smack!
“H-huhiit?!”
Ripples spread across her flesh in concentric waves from the point of impact.
Hoo… The texture is incredible…
This voluptuous meat had a perfect hand-feel. Every slap made the sticky flesh cling wetly to my palm with a satisfying smack. Then her ass would quake like an earthquake, and the vibration traveled back into my hand. When I lifted my palm, a clear pink handprint stood out vividly against her snow-white skin.
“Ha, hu, haat… Hu, haa… This is weird… Your p-palm… feels stronger than usual…”
Park Seoyun pushed her ass out further, wiggling it cutely.
“Again… Spank me again… My butt… Hurry…”
A thick strand of pussy juice dangled from her cunt, swinging heavily. The way she shook her ass while begging to be spanked, her juices swinging like a pendulum—it was ridiculously lewd. Previously, she had only been spanked out of curiosity and hadn’t liked it much. Naturally, because it hurt. But today, thanks to the aphrodisiac, she seemed to love it. To think she would shake her own ass and beg to be hit… It was insanely arousing.
“Haa…”
Letting out a sigh mixed with pleasure, I slapped the same spot on her ass again.
Smack!
“Hngaaat♡!?”
The sharp, tingling sensation in my palm made my cock twitch on its own. Her pussy and asshole fluttered wildly, and a powerful squirt erupted from her cunt. Her ass repeatedly clenched and released like twerking, as if she had just experienced a small orgasm from that single slap.
“Haat♡ Haaat♡ W-what do I do…! It’s weird, my a-ass…! My ass feels so strange… It won’t stop…! The trembling won’t stop…♡”
I grabbed her wildly wriggling ass with both hands and spread her cheeks wide. Then I pressed my glans firmly against her twitching anus.
“Huaat♡ Ha, haat♡ W-what is, u-uaaa♡ Weird, it feels so weird♡”
When I pushed my hips forward slightly, the glans forced open her incredibly tight hole and slid inside. About halfway in—
Schlurp—
Her anus spread wide before suddenly swallowing the rest of my glans whole.
“Whoa… No, fuck…”
“Hu, hong♡ Huoong♡ I-it’s in…! What is this, what’s inside, nngaaat♡ It’s so thick…! A thick bead, a big thick bead is inside me…!”
She called it a big bead even though it was just my glans. Once again her ass began twerking violently. Park Seoyun’s legs trembled as they slowly gave out. Her hips started sinking downward. I slipped my arm under her pelvis and lifted her up to stop the descent.
I pushed my hips a little further. Another three centimeters of my shaft sank in.
“Hu, huooong♡ Kk, kkut, kku, i-it’s going in, huooong♡ W-what do I, kkuhuuugt…”
Her legs folded more and more until her thighs pressed against her calves. With only her upper body on the bed, she was now suspended in the air, held up by me. She clutched the sheets tightly before pressing both hands against her own chest. At this point, she really did look like a giant onahole.
Fortunately, thanks to my Strength Enhancement skill, holding her up wasn’t too burdensome.
“Kkut, guk♡ Huht, kkuguk♡ Aht, ak, kup…♡”
She could no longer even moan properly, only shivering violently. I moved my hips slowly—intentionally slow. I pulled her pelvis toward me. And then—
“Ugh, fuck… Huaaa…!”
“Kkut, ka, ak…♡”
My pubic bone buried itself into her massive ass cheeks. Park Seoyun’s belly had swallowed all twenty-two centimeters of my massive cock. Her legs began folding again. What had only been bent at the knees now folded completely, her thighs pressing against her stomach. Her once-straight waist curved upward. Suspended in the air, she looked like she was bowing in worship.
“Kkup, ha, hak♡ Ha, hat, hak♡”
She was breathing heavily, but the sound seemed slightly dangerous. It looked as though something large and thick was piercing through her body and pressing on her insides, interfering with her breathing.
Wait, fuck…
Park Seoyun was in danger in her own way, and I was in danger in mine.
“Kkup, haaaa…! What kind of hole… ugh…!”
Holy shit, how could a hole like this even exist?
It’s so fucking hot…!
Park Seoyun’s hole was unbelievably hot. Her body already ran hot, and her rectum was the hottest part of all. Being inside it felt like my cock might actually get cooked. On top of that, perhaps because of the temperature, the intestinal walls were incredibly soft and sticky. They clung to my cock like freshly steamed rice cakes. And that wasn’t all.
My cock… is trapped…!
The thick sphincter at the entrance had clamped down hard on the base of my shaft. During entry it had only been a dull tightness, but once I was fully inside, it suddenly gripped me like a vice. Blood couldn’t flow properly, making me swell until I felt like I would burst. I had broken through the limits of erection. Park Seoyun would definitely be feeling how much thicker I was than usual.
“Ho, hoooook♡ Y-your cock, it’s so big♡ Way too biggg♡”
“Kk, aap…! S-stop…! Stop moving!”
When I had first entered, the inside of her ass had been full of intricate folds. Every surface was covered in deep, distinct wrinkles like oden cakes. But the moment I bottomed out, the interior changed completely. Those “oden-like” wrinkles weren’t just wrinkles. The moment the sphincter locked my cock in place, the folds stretched out fully before sliding back with a wet schlick, repeating the motion. The same movements meant to push out waste were now being used to milk my semen.
But fuck, the direction is all wrong…!
It was strange. The rectum was supposed to move in the direction of expulsion, yet it kept pulling my cock deeper inside. With my cock now held hostage by her asshole, the same question rose in my mind again.
Is this because of the Erogenous Zone Development? Or is she just an anal genius?
“S-stop moving the inside…”
“Hnguk♡ Kuk, kkup♡ Hatkuk♡”
It seemed Park Seoyun had no room to hear my desperate cries. The constant wriggling of her intestinal walls sent dizzying pleasure straight to my brain, turning it white. At this rate, I felt like I would cum without even moving once.
First… First I need to pull out and think.
I began pulling my hips back very, very slowly. Then something incredible happened.
What the…
At first, her anus clung to my cock like a vacuum cleaner, stretching outward with a wet schooop. But the more I pulled, the tighter it gripped. Now her entire body was being dragged backward along with my cock.
Huh, ugh…! Fuck… What the hell is this…! It feels like my cock is going to get ripped off…!
This anal pussy was on another level… Could I really hold back from cumming until I pulled out completely? I had no choice but to grab her waist and hold her in place. Only then did my cock finally begin to slide out.
“Kkuk, kuooooong♡!! Huoong♡! Huooooooong♡!!”
Park Seoyun began screaming from the strange sensation of something huge leaving her asshole. Her toes curled tightly. The lack of blood flow made them turn white. The hands that had been clutching the sheets slammed against the bed repeatedly. Her ass started twerking again. At the same time, her pussy sprayed a powerful jet of fluid toward the floor.
Pssshhhhh—
“HuoOOOOONG♡!! Kkut, huhtkukkuoong♡!! Haooong♡!!”
Fortunately, thanks to the love gel coating my shaft, the withdrawal speed gradually increased. Her anus caught on my glans again, stretching outward, but with one powerful thrust of my hips, I managed to pull free. The moment even my glans escaped—
Pop—
A refreshing sound like pulling a cork rang out.
“HuoOOOOOOOOONG♡!! Hunggaoooooong♡!!”
Park Seoyun’s folded legs shot straight out in one motion. Her straightened legs kicked against the floor, lifting her ass high. The tremendous amount of fluid from her pussy scattered magnificently in every direction.
“Haong♡! Huaoong♡ HuoOOOOONG♡!”
With her legs stretched so rigidly they looked like they might snap, Park Seoyun trembled dangerously while continuing to squirt. Her large ass still shook violently in a lewd twerk. The hole between her cheeks gaped open, mourning the empty space my cock had left behind.
“Haa… Haa…”
Watching that utterly obscene and vulgar sight, I stroked my still-unsatisfied cock. It was so fucking hot… In all my life, even in porn, I had never seen anything like it. My cock seemed to have already forgotten the terrifying nature of that hole and was drooling precum, screaming to be let back inside. Before I knew it, I had grabbed her pelvis again and was aiming my cock at her asshole. Even though she wasn’t looking back, her anus fluttered in anticipation of what was coming.
Squelch—
“Huht, kuk…!”
This time it slid in smoothly with almost no resistance.
Ah… Fuck, it feels so good…
The thick sphincter clamped down on my shaft again, but thanks to the love gel, I could move back and forth freely.
Smack, smack, smack, smack!
Her pale ass rippled violently. The sticky flesh clung tightly to my pelvis before pulling away, over and over.
“Huuuk, heuk…!”
The soft, chewy intestinal walls inside wriggled greedily, trying to extract my semen. Her anal walls sucked my cock deep while simultaneously chewing on it with wet, obscene sounds.
“Haaak…! Fuck, this is too good…!”
With my mind gone completely white, I thrust my hips like a mindless monkey. Was I fucking an onahole? Or an asshole? I didn’t know anymore. It just felt insanely good… Smack, smack, smack, smack, smack! My waist was starting to ache, and somewhere I could hear the violent sound of flesh slapping against flesh. Was that coming from Park Seoyun’s ass? Was I really pounding her that hard?
“Hnguk, kuk♡ Keokhauk♡ Hek♡ Heok♡ Hoguk♡”
When I briefly regained some sanity and looked down, Park Seoyun was shaking like a broken doll, tears, snot, and drool pouring down her face. Her ass had turned bright red from how hard it was slamming against my pubic bone.
Smack, smack, smack, smack, smack!
“Haaak… Haaak…! F-fuck… I don’t know anymore! What am I supposed to do when Noona’s asshole feels this good?! It’s your fault, Noona! Heuk, fuck…!”
Even as I spoke and kept thrusting, the urge to cum surged upward. I had no idea how long I’d been pounding her for it to reach this point. It was truly a murderous hole.
“He, ok♡ Hook♡ I-I’m dying…! I’m dying♡ Heek♡”
Park Seoyun thrashed about in agony. Her anus, perfectly developed by Erogenous Zone Development and having absorbed every drop of the aphrodisiac with its incredible absorption power, was granting her owner pleasure so intense it was painful.
Smack! Smack! Smack! Smack! Smack!
“Ha, haoooong♡ Hek, heoguk♡ I-I’m really, ok♡ Dyinggggg♡!!”
Between her violent reactions and her fists pounding the bed, the bedframe let out deathly creaks.
“Fuck! Get pregnant! Get pregnant through your asshole!”
“Huht, kku, aaang♡ M-mommy… Hnguk♡ S-save meee… Save me, hoooook♡!”
Park Seoyun’s eyes were slowly rolling upward. Her breathing was labored, her chest rising and falling irregularly. The sight was starting to look genuinely dangerous.
Smack! Smack! Smack! Smack! Smack!
“Ek♡ Hek♡ Kek♡ Kkgek…♡ Heguk…♡”
Whether it knew its owner’s plight or not, this murderous asshole continued to cling wetly to my cock, squeezing and sucking with desperate greed. I slapped her ass hard with my hand.
Slap!
“Hi, heeeeek♡”
“I’m cumming! Squeeze! Squeeze that asshole! Hurry!”
“Hu, huoong♡ Again with the shit ho, kkuoooong♡”
With the force of someone trying to hammer her into the bed, I slammed my hips down like driving a nail.
Thud—
“Kkuup…!”
My cock swelled as if it would burst, my balls tightening up. My waist trembled violently from the overwhelming urge. By now I had completely forgotten whether this hole was an asshole or a pussy. My snow-white mind simply sprayed thick semen into the hole to impregnate it.
Spuuuuurt— Spurrrrrt— Splurt, spuuurt—
“Kku, huoOOOOONG♡!! Kkuooong♡! Haoong♡!”
Splaaaaash— Park Seoyun’s legs shot straight out, and an enormous amount of fluid gushed from her pussy. Her ass convulsed violently as if twerking. Her eyes had long since rolled back completely. Only her asshole, like a starving beast, continued to suck on my cock like a straw while chewing wetly.
It was seriously a fucking insane hole…
“Heuk, kkuuuup…!”
Spuuurt— Spuuuuurt—
“Kkut, kuguuuuk♡ Hauuuuung…♡”
Park Seoyun’s wrinkled anal walls performed intense milking motions, squeezing out every last drop of semen. I enjoyed the movement of her intestinal walls and the lingering sensation for a while. Then, slowly, I pulled my hips back.
Plop—
“Ha, haoooooooong♡!! Huoong♡!!”
Park Seoyun, who had barely begun to calm down, started thrashing again. Splurt— Splurt, splurt— Thick semen shot out from her narrow asshole. Thanks to the Enema skill having cleaned her completely, there wasn’t the slightest hint of filth—only pure lewdness.
“Hu, huoong…♡ Heeeeng… Hueeeeng… Mommy… Mommyyy…”
Park Seoyun cried out at the top of her lungs. Her entire body was drenched in sweat, her chest flushed bright red as she sobbed pathetically. The sight made my eyes roll back with renewed lust.
“Forget Mommy, you bitch… Lie down, now!”
“Heeeeng… Ueeeeng…”
I flipped her body over so she faced the ceiling, then lifted her ass so her asshole pointed upward. The hot pink hole twitched obscenely, spitting out thick globs of semen. Like a fountain, the milky liquid shot straight up.
“Kkureuk…♡ M-mommyyy… Something keeps coming out of my asshole… Mommyyy…”
Still lost in pleasure and ecstasy, she kept calling for her mother. It was somewhat pitiful, but I was still completely consumed by lust.
“Don’t worry, I’ll plug it up for you…!”
Right as her asshole spread open, I thrust my cock back inside.
Squelch!
“Hu, huoOOOOOOOOONG♡ HaoOOOOOONG♡”
Smack! Smack! Smack! Smack! Smack! Smack!
Today, I swore I would wreck this hole completely.
