I Gotta Pee... – Squish...!
I felt like I had to pee – squish...!
"Haaang...♥"
Along with a strangely lewd, sticky sound, Ye-eun Seo's fingers parted my pussy and delved inside.
This sensation of my narrow inner walls, which had never taken anything before, gently wrapping around the foreign intruder.
The stimulation was so intense it nearly made me black out, and my body started trembling wildly on its own.
"How's it feel? Good, right?"
"Huu, ugh... wait... haaht...!"
"Can't even speak properly 'cause it feels that good~. Who knew our little puppy would love it this much."
Ye-eun grinned down at me.
Her face, seen through my hazy daze, brimmed with all sorts of emotions.
Possessiveness, obsession, dominance, ecstasy, and an unrelenting fixation.
Lewd feelings that no friend should ever have for another started crashing over me.
Oh, this is dangerous.
Getting my pussy fingered by a girl like this...
- Squelch, squelch
"Hauk, ut... huaaht!"
"Guess I'll go a little harder then~."
Right then, Ye-eun's fingers, slick with my juices, began slowly thrusting inside me.
This was on a whole different level from anything I'd felt before.
Even when I masturbated alone and just barely slipped a finger in, it creeped me out so much I pulled it right back out.
But now, someone else's fingers were pushing in against my will, and it felt like my mind was about to shatter.
- Squelch, squiiiish... squelch!
"Hau, wait... hungyt?! Haaang...!"
"It's okay, it's okay. Relax~."
"H-how do I relax... hiiiiiik!!"
Every time her fingers slid in and out, electric jolts raced up my spine.
This feeling of someone else's fingers – not mine, not under my control – ravaging my most sensitive spot.
This alien sensation was chillingly stimulating, wrapping around my body in a thick, sticky embrace.
"Huu... haaaang! Ye, Ye-eun... ahat!"
"It's fine, just slowly let go~. Your insides are clenching so tight, it's hurting my fingers."
"B-but... uhaeut?!"
"No helping it. I'll adjust your position a bit."
Ye-eun pulled her hand out of my pussy and stood up, moving behind me.
She pressed right up against my back as I crouched on the floor with my arms raised, wrapping one arm diagonally around my stomach to support me firmly from behind.
With her other hand, she reached between my spread legs, fingering my pussy at an even deeper, more blatant angle.
"W-wait... from behind like this, ahat?!"
"This position lets me reach way deeper inside. Our puppy likes it better this way, right?"
"A-ah... th-that's...!"
Her arm braced my stomach so solidly I couldn't escape or arch my back away from the pleasure.
I could only bounce helplessly in time with her rough thrusts.
- Squiiiish, squelch! Squelch!
"Huuk, ut... huuuung!"
"Feels good, huh? Then I'll really go for it~."
"Uuu... hiiiiiik♥"
Ye-eun's long fingers relentlessly violated my tight hole.
She leisurely explored my insides, bending and pressing firmly in various spots.
I don't know why, but every place her fingers touched felt different.
Pressing near the entrance just hurt unpleasantly, but when she thrust deep and scraped gently, my lower belly tickled intensely.
And in other spots I couldn't even describe, the sensations overwhelmed me as her fingertips scratched and prodded.
This is weird.
This feels so freaking weird♡
"A-ah! Haaang! I-it's weird..."
"Where's it weird, Seo-jin?"
"I-I don't know... hwuuk?!"
Her fingers, probing deeper and deeper, suddenly brushed a specific bumpy spot inside.
In that instant, my lower belly swelled like it would burst, pressing hard on my bladder in a bizarre, dizzying sensation.
"Ye-Ye-eun...! Th-there, it's weird! Huwt... j-just now..."
"Yeah? How's it weird?"
"I-it feels like... hiik! I gotta pee..."
"Really?"
"I'm gonna pee, so stop for now..."
- Squelch...!
"Hiiiiiiik!"
I tried to clamp my legs together in panic, but Ye-eun wouldn't let me.
Her arm around my stomach tightened, and the fingers inside my pussy sped up.
Goosebumps erupted over my whole body again, my strength drained away, and my lower belly grew hot and heavy.
Something's coming.
I don't know what, but it's coming!!
"Oh my, puppy. That's not the urge to pee."
"Wh-what...?"
"Your body's telling you what real pleasure feels like. So just relax and let go~."
"N-no! Really, hiik! I'm really gonna pee...!!"
Ignoring my desperate pleas, Ye-eun shoved two fingers deep inside.
She wriggled them slowly toward that spot she'd grazed before, then flicked the tips upward hard against it.
"Huyaaat...?!!!"
In that moment, my mind went pure white.
A flash exploded before my eyes, and explosive pleasure like my veins would burst slammed into my brain.
I was too stunned to comprehend what was happening when Ye-eun's fingers mercilessly ravaged that spot.
That's when I realized it.
This is gonna make me lose it. No doubt.
"No! Noooo! Stop, pleeeease stop!!"
"So this is Seo-jin's weak spot, huh?"
"I-I don't know... hauk! Stop, hik...! My head and body...!"
"That's called cumming. Wanna try saying it?"
"C-cumming? Cumming...! Hungyt?! I-I'm cumm... hiiiiiik!!"
I let out a beastly wail, my back arching like a bow.
Indescribable stimulation flooded me, and my body went beyond its limits, collapsing out of control.
Hot heat boiled up from deep in my gut, making my lower belly burn.
And when Ye-eun's fingers playfully nudged that spot one last time.
- Press!
"Huut?!"
What I'd been holding back gushed out all at once between my legs.
- Spliiiish!
"Unghuuuut———!?!♥"
A transparent, hot liquid sprayed out like a fountain, slicing through the air and soaking the living room floor.
I squirted. I totally squirted.
I didn't even know if it was pee or what, but it poured out wildly, dribbling around Ye-eun's fingers still buried inside me.
"Oh dear, you squirted?"
"Huu, uuk... Wh-what was thaaat..."
"Looks like we need more potty training~."
"Haa... haa... aaa..."
"It's okay~. First time, so it's normal."
My brain felt melted, leaving me dazed.
My raised arms flopped limply to the floor, and my crouched legs splayed out ugly to the sides.
With every ounce of strength gone from my fingertips, I trembled in Ye-eun's embrace from behind, panting hot breaths.
What the hell was that...
As the pleasure filling my head washed away somewhat, a sticky fear started to take its place.
"Still, you said you were cumming so nicely when you did. Good girl, Seo-jin."
"Hunguut..."
"At this rate, you'll make a really great puppy."
Ye-eun, pressed tight against my back, whispered softly into my ear.
She licked my earlobe gently and placed her right hand on my stomach.
"Ye-Ye-eun..."
"Lift your head and look~. See who's here right now."
I slowly raised my head as she said.
My gaze fell on the huge full-length mirror that had been blocking my view this whole time.
And there...

"Ah..."
A single lewd bitch panted for breath.
In the mirror, I was collared like a dog, held from behind by Ye-eun.
My face was flushed red with pleasure, lips gaping slack as I panted, drool spilling because I couldn't swallow.
But what drew the eye most was between my legs.
Ye-eun's fingers buried deep, the living room floor a mess from the clear liquid I'd just sprayed, my thighs soaked.
A perfect... bitch in heat.
'I'm... enjoying this...'
The me in the mirror had melted completely under Ye-eun's touch, savoring the pleasure with her whole body.
This lewd, vulgar sight...
Seeing undeniable proof with my own eyes that I'd become a total bitch, the fragile thread of reason I'd clung to in my mind started to shake dangerously.
"So pretty. Right, Seo-jin?"
"Haa... huu..."
"But what now? We've only just put in a few fingers."
Ye-eun nibbled my earlobe, whispering in a deadly voice.
"I was thinking of letting you feel something even more intense. What do you say?"
"......!"
"Shall our puppy cum one more time?"
Something even more intense.
I didn't know exactly what she meant, but my instincts screamed warnings like mad.
Just that pleasure alone had nearly broken my mind – what if I took something deeper now?
I didn't know. But instinctively, I understood.
If that happened, my body and mind would change for good, and I'd never return to being normal Seo-jin Lee.
"Ah... a-ah..."
I had to refuse. Say I didn't want it, beg her to stop here.
But my lips only trembled; no voice came out.
The sight of my horny self in the mirror held me back.
Right now, I was just a pet.
Could a pet like me defy Ye-eun, my owner?
'No... this isn't... no...!'
I had to refuse.
Reason screamed in my head that going further might erase human Seo-jin forever.
But the bitch's instinct to obey her owner mechanically was suppressing it.
"No answer, puppy?"
"W-waiiit..."
"Guess that means you want more~."
As I hesitated, Ye-eun's fingers inside my pussy started moving slowly again.
- Squelch
"Hauuuung?!"
"Oh my, already feeling it."
"Haa, auu..."
Even a single friction made my hypersensitive walls twitch, sending shivers racing up my spine.
If this kept going, it was really over.
Instinct told me even a moment's hesitation meant no turning back. I squeezed my eyes shut.
And mustered every last shred of reason to scream.
"B-ba... banana...!! Bananaaa!!!"
My cracked voice echoed desperately through the living room.
