We're Friends, Aren't We, Seojin?
“We're friends, right, Seojin? 'I guess it's time to take it out now?'”
“H-hee...?”
It happened before I could even grasp what she meant.
Seo Ye-eun gripped the tail firmly lodged in my asshole and yanked it out in one merciless pull.
- Pop!
“Hiiiiiik—?!!”
With an intense sucking sound as it came free, the thick metal plug scraped along my inner walls and slipped out in an instant.
The vacuum-like emptiness that suddenly formed where I'd been filled so completely, combined with the violent drag across my mucous membranes.
I twisted my entire body from the unfamiliar, explosive sensation, flopping around on the bed like a fish out of water.
My vision went pure white, and I couldn't even catch my breath.
Suddenly pulling it out like this... no, don't...
“Haa, haa... hngh...!”
“Oh my, getting off this much just from having your tail pulled out. I wonder what'll happen when you get a real reward?”
“H-hee...!?”
As I panted and trembled, a sinister whirring buzzed right by my ear.
I turned my head to see Seo Ye-eun approaching with that grotesque U-shaped vibrator in hand.
Staring at it with eyes full of dread and anticipation, she deliberately pressed the remote button hard, as if to show off.
- Vrrrrmmm!
“Hiiiik!?”
“Our little puppy's probably feeling amazing right now, huh?”
“H-hngh... ughhh...”
Just looking at the thing thrashing wildly made my thighs quiver uncontrollably.
What would happen if something that vicious got shoved inside me?
Into my slick, dripping pussy and my loosened asshole, still ravaged from the plug moments ago.
Captured by thick dread and a bizarre anticipation, I could only gasp for air when Seo Ye-eun pressed the two prongs right up against the cleft between my legs.
It's coming. That monstrous thing is finally going in.
I trembled violently, squeezing my eyes shut, waiting for the intense pleasure to hit.
But.
“Ah, hn?! Hngh...?”
“Our puppy's already leaking so much.”
Seo Ye-eun didn't thrust it in all at once.
Instead, she just teasingly grazed the tips of the thick, viciously vibrating prongs over the entrances to my secret holes.
My pussy, soaked from repeated abuse, and my asshole, still twitching sensitively from having held the plug.
Those vulgar, vulnerable weak spots began to be lightly toyed with by the cruel vibrations.
- Bzzz, vrrrm...
“Hiiik! Ah, aaah...! Haaang...!”
“Feels pretty good, doesn't it? Nice and sneaky like this.”
“Hngh, uungh...!”
Teasing, so close to entering but not quite, touching but pulling away.
Relentlessly stimulating only my swollen clit and the shallow wrinkles around my asshole drove a maddening thirst up from deep inside.
Every pass of the vibrations over my skin sent jolts through my lower belly, and more juices gushed out between my legs.
I want it inside. I want to shove that thrashing beast into my holes right now—I'm going crazy for it.
“Hnggg...! W-woof, woof! Haaang!”
Bound in handcuffs, I twisted my hips, thrusting my ass back to impale myself on it.
But every time I desperately offered myself up, Seo Ye-eun wickedly pulled the toy away.
“Oh dear, I haven't said reward time yet—why's our puppy shoving her ass out on her own?”
“Haaang...! P-please...! Hngghik...!”
“Please what? What do you want me to do?”
“Please... haaang! Put it... in meee...! Fuck meee...♥”
Completely lost to reason, I begged like a bitch in heat.
A perfectly corrupted slut-dog pleading with her owner to stuff her holes. Watching me like this, Seo Ye-eun let out a satisfied chuckle.
“Alright, our good puppy. If you want to be fucked that bad, I'll give you a nice, heaping reward.”
“Hngh...”
“Here comes your reward.”
The words had barely left her mouth when she moved her hand.
The two massive prongs plunged mercilessly into my drenched pussy and loosened asshole.
- Squelch!! Thud!
“Hiiiiiiit——!?!!”
Both holes were filled to the choking brim at once.
My inner walls on both sides were crushed by the outrageous girth, and the U-shaped bend pressed relentlessly against my most sensitive perineum.
The violent, overwhelming double-sided pleasure I'd never felt before.
The thick protrusions inside thrashed madly, scraping mercilessly at every erogenous zone.
“Haaaang! Hnggg... Ah, aaaah♥ Woof! M-meeeow!!”
“Oh my, our puppy. Feeling good?”
“Hee... Woof! G-good...! Haaht♥ It's shaking so much insiiiide♥”
“That's right—it's a special reward for our puppy~.”
“Ughhh...”
“I'll make you feel it properly~.”
Seo Ye-eun smiled and pressed the remote button to my ear.
The vibrations grew even more ferocious, the toy buried in both holes ravaging my walls without mercy.
Handcuffed, I clawed at the bedsheets, trembling uncontrollably.
Beast-like moans kept spilling from my mouth.
It feels so good, I'm gonna lose my mind—it's that good.
“Haaang...! Ah, ungh...! Hn, hnggg...”
“How's that? Feel like you're about to cum properly?”
“Hee, ugh... huuuu♥”
“Not quite yet, huh~.”
Even amid that pleasure, I couldn't reach a satisfying climax.
The massive stimulation had me on the edge, but somehow, it was missing just 2 percent.
That 2 percent kept my swollen ecstasy circling endlessly in my gut, teasing without release.
Why is this happening? My brain's melting, but I can't reach the end.
“Hmm? Why's our puppy reacting like this?”
“Hik, uh...! Uhuuuk!!”
“You look like you wanna cum so bad, like you're about to burst any second, but you just can't?”
Watching me writhe in overwhelming pleasure without crossing the threshold, Seo Ye-eun tilted her head.
You know. You definitely know why...!
Even as the toy vibrated insanely inside, crushing both holes, I couldn't cum—I just whimpered like an animal, desperate and frustrated.
“I wonder why our puppy can't cum?”
“Hngh, ugh...! Ah, aaaang...!”
“Aha. I get it now~.”
Seo Ye-eun brushed my wet hair back and whispered like a devil.
“Our puppy needs more than just the toy, doesn't she?”
“Hii...?”
“Watching you shake your ass while Hye-won spanked you earlier... looks like you've turned into a pervert bitch who can only cum properly with pain mixed in?”
“Hiiik...?! N-no... that's not... nooo...!”
“Oh, it's totally obvious.”
I shook my head in denial, but my body screamed that she was right.
My body, awakened to pleasure amid that merciless spanking, now needed tearing pain to flip the switch to climax.
So if that's what it took to break my blocked orgasm...
Seo Ye-eun reached out and picked up the leather paddle tossed on the bed.
In that instant, I instinctively knew what she was about to do.
“How about your owner helps you out?”
“N-nooo...! Hngh, d-don't spank... meee...!”
“Really?”
“Unngh...! If you spank me now... hik♥ I'll really go craaaazy...”
I really would go crazy.
In this state, getting my ass beaten might mean I could never go back to being a normal person.
I sensed it instinctively and begged her not to, but...
My body had reflexively twitched my ass toward the paddle the moment I saw it, craving pleasure.
At that blatant, vulgar reaction, Seo Ye-eun smiled leisurely.
“Your mouth says no, but your body's so honest.”
“W-wait a sec...”
- Smack!
“Haaaaht!!”
“I'll make it easy for you.”
The sharp whistle through the air, then the paddle struck my already swollen-red ass once more.
But this time, the impact rippled differently.
Each strike made my sphincter clench reflexively, squeezing the U-shaped toy buried inside without mercy.
The sharp pain of flesh being struck traveled through the compressed toy, hammering and shattering the final dam blocking my climax.
- Smack! Whap! Squelch!!
“Hi, giiiit! Woof! M-meeeow♥”
“That's it, feel it good. How's it feel getting punished and rewarded?”
“Aaaang! Hik.... Hiiiiaht...?!”
The perfect combo of whipping and vibration.
Pain ignited the pleasure, sweeping through my body, and the blocked threshold finally crumbled to pieces.
My mind went white as intense orgasm surged up my spine.
I'm cumming. This is the real deal—I'm cuuuumming♡
“Hn, uwoook...! Hiiiiiiiik!?♥!”
With a scream that tore my throat, my body arched high off the bed.
My handcuffed arms shook violently, my back bowing like a drawn bow.
At the same time, the hot fluid filling my belly erupted like a fountain, soaking the sheets and even the back of Seo Ye-eun's hand gripping the toy.
- Spiiiish!!
“Haaaaaaaahk...♥”
“Whoa, impressive. Our puppy's pussy is gushing like crazy this time.”
“Hngh, uughhh...”
“At this rate, we could install a fountain~.”
Having reached that massive climax, all strength drained from my body, and I collapsed.
Amazing, feels so good. I love this...
Tears and drool streaming down my face, I slowly sank into the swamp of mingled pain and pleasure.

How much time passed?
As my body still quivered with aftershocks, Seo Ye-eun slowly withdrew the U-shaped toy.
- Squelch, pop.
“Ah, ungh...”
“Alright, time for our puppy to take her reward and go?”
“Hngh...♥”
The scraping withdrawal made me buck my hips again, leaking another lewd moan.
Is it finally over?
Seo Ye-eun came over and unfastened my collar and handcuffs.
Freed from restraints, I still lacked the strength to move a finger, sprawled on the bed and panting.
She smiled at me, brushing back my sweat-soaked hair, her voice soft and gentle.
“You did great, Seojin. You threw yourself into the training wonderfully today~.”
“Unngh.... Nooo...”
“You did so well today that to properly end this play... could you say the safe word yourself, Seojin?”
“Hngh...? Safe... word...?”
I rolled my unfocused eyes in confusion.
The safe word. The magic phrase we'd set firmly before starting the roleplay.
But amid the insane pleasure and pain, reduced to a whimpering beast, that word had melted away into a white haze, buried deep in my memory.
No matter how I ransacked my mind, it wouldn't come.
As I just trembled like an idiot without answering, Seo Ye-eun grinned and gently cupped my cheek.
“We're friends, right, Seojin~? You can't stay a puppy forever, can you?”
“......Ah.”
Friends. We're friends.
That word triggered the memory sunk deep in my mind.
Safe word: friend.
I have to say it. That's how I turn back into a person.
Lips quivering, I choked out the word in a tearful whisper.
“...Fr, iend...”
The moment I said it, the magical tension gripping my body melted away.
It's done. Finally... over.
Seo Ye-eun beamed with her usual kind friend's face.
“Yep. Good job today, Seojin. Rest up—we'll see each other at the academy tomorrow.”
“Uungh...”
Hearing her gentle voice, I let the languid heaviness pull the strength from my body as I lay on the bed.
Relief that this insane roleplay was over tangled with a weird anticipation of what might come next, swirling in my chest.
I don't know, I wanna sleep.... For now... I just want to rest.
Pushing aside complicated thoughts, I drifted off as human Lee Seojin once more.
