Puppy's Reward and Punishment
As our puppy Im Haeun emerged from the adult store, we quickly grabbed her and hurried back to the van. On the way back, unlike Haeun's sullen pout, Soye was grinning like she was having the time of her life.
"H-here...." Inside the van, Im Haeun handed over the items she'd bought. Shin Soye nodded, urging her to open it. I peeked into the bag and was a little surprised.
"Extreme thin...?" 'EXTREME THIN 0.02'. As far as I knew, it was the thinnest condom sold domestically.
"Buying the thinnest one... You wanted it that bad, huh?"
"W-what?! No, I just grabbed the first one I saw...!" Haeun bristled at my words.
"......."
And Soye just stared at her silently.
"Haeun-ah."
"Y-yeah, unnie."
"Looking forward to it that much? You got the one that feels the best."
"N-no, I just took the first—" Haeun started protesting but cut herself off. The smile Soye had worn all night had vanished from her face.
"Fine, if you're that excited... we should have fun with it, right?" Soye flashed her grin again. Her voice was gentle, but the warmth had faded a bit.
"Sejin-ah. Let's go to your room."
"Got it."
"Come on, Haeun-ah?" Soye turned back to Haeun with a smile. Haeun could only stay quiet and still.
We parked the van in front of my room and headed back inside, with Soye still keeping the leash on Haeun the whole time. But it felt less like a dog leash and more like the iron chain on a condemned prisoner. Probably because Haeun looked like she was on her way to the gallows.
"Mm, been a while since we've been back at the room." Soye said as we entered.
"Haeun-ah, this is your first time, right?"
"Y-yeah."
"Good thing. Looks like you're the only one I've let into my room...." Soye murmured softly. She tugged the leash and led the way inside.
"Come in, Haeun-ah~"
"......."
Soye dragged Haeun to the center of the room and commanded,
"Sit here."
"O-okay...."
Haeun hesitated before sitting. Soye pulled out the dildo Haeun had just bought.
"N-no way, you're gonna use that...."
"Didn't you figure it out when I told you to buy it?" Soye replied with a grin.
"U-unnie... what are you—"
"Gotta play with our puppy~"
Soye moved behind Haeun, sat down, and stripped off her coat. Then she quickly peeled away the rest of her clothes, leaving her stark naked.
"You went out, so time to get naked~"
Soye pinched Haeun's nipples between her thumb and forefinger.
"Nngh, ow, unnie... it hurts...."
Haeun let out a pained whimper under the torment. Soye seemed to savor her reactions, tormenting her for a good while longer before pulling out the condom Haeun had bought.
"Now, let's combine our puppy's purchases~"
Soye held the dildo in front of Haeun's eyes and slipped the condom over it. Her movements were a bit clumsy, so it took a while—I helped out.
"Thanks." She giggled, then brought her empty hand to Haeun's pussy. She lifted it suddenly, feigning surprise.
"Oh my, you're already all ready?"
"T-this is...."
"Our puppy's such a total perv. Getting this wet just from a walk and a dildo."
Soye slid the dildo right into Haeun's pussy.
Squelch.
"Nngh...!"
It went in smoothly.
"It's a bit smaller than yours, Sejin-ah. I told her to get one the same size."
"I-I tried to get the closest match... hngh, I did!"
"No you didn't~?"
"H-how would I know his exact size!"
"...Is that so?" Soye looked mildly surprised. But only for a moment.
"Well, close enough is fine." Soye kept tormenting Haeun, shoving the dildo all the way in and twisting it around with her hand.
"Nngh, ngh...." Haeun started leaking little moans. Pleasure began mixing with the pain.
"Oh? Puppy's reacting already?"
"T-that's...."
"They said you've had lots of training—guess it's true. Getting wet and sensitive so fast."
"No, it's just... haah...!"
Soye stopped twisting and started pistoning it back and forth, making Haeun react big time.
"Don't lie~ You're loving it this much?"
Squelch, squelch.
Haeun twitched with every movement of the dildo. Even though Soye scared her, the pent-up lust from the past few days had her whole body responding in no time.
"Ngh, nngh, haak, uk, nngh...!"
"Your moans are so cute~ So slutty."
"Nngh, ahng, u-unnie... nngh...!"
Haeun's juices dripped from her pussy, soiling the floor, and soon her spot was a mess.
"Ah, haah, nngh, nnngh...!"
It didn't take long to reach climax. Soye mercilessly pounded her pussy with the dildo until Haeun shuddered all over and squirted her juices.
"Haa, haah, haa, haa...."
"Oh my, you came already? Was the dildo that good?"
"T-that's... haak, haa...."
Haeun panted heavily. Soye watched for a moment, then spread Haeun's legs.
"Master~?"
"Yeah?"
"This spot looks messy. Can you clean it up?"
With that, Soye spread Haeun's pussy with her fingers. The pink flesh, tinged red, bloomed open like a mouth. I leaned down and pressed my lips to it.
Slurp, slurrrp, sluuuurp...!
Haeun bucked as I sucked her soaked pussy.
"Nngh, I-I just came...! Ahh, ahng, haa...!"
I ignored her and kept sucking eagerly. I latched onto her protruding clit like it was erect and swirled my tongue inside her pussy. At the same time, Soye relentlessly teased her nipples, kneading her breasts and pinching the tips, drawing moans from Haeun each time.

"Nngh, haa, haaa...!"
At this point, I was getting seriously turned on too. I pulled my face from Haeun's pussy, stood up, glanced at Soye, then dropped my pants and pulled out my erection.
"Haa, haa, haa...."
Haeun panted as she stared at my cock. Right in front of her eyes, I rolled on the condom she'd bought and sat facing her, ready to thrust in....
"Hold on."
Soye stopped me.
"Haeun-ah, that's not how a puppy sits, is it?"
"Again... why...."
"You gotta do it puppy-style~?"
Soye yanked Haeun and flipped her around onto all fours, then lifted her ass herself.
"There, that's more like a good puppy."
She grinned and grabbed my body.
"Come on, Master~ Time to reward the puppy."
I slid my cock into Haeun's pussy. The hole already loosened by the dildo swallowed me right up, clenching tight in welcome like it had been waiting.
"Hngh...!"
"How's it feel, Haeun-ah? Sejin's is bigger, right?"
"I-I dunno...!"
"A good puppy should know her master's size~ Sejin-ah, show her right away. Rough."
Squelch, squelch, squelch....
As Soye asked, I started shaking my hips immediately. The moment I was buried inside Haeun's pussy, I pistoned hard and fast. In the middle of it, Soye started fondling Haeun's ass.
"Haht, hng...!"
"Our puppy has such a pretty little hole."
"N-ngh?"
Soye smirked meaningfully and slipped a condom onto her index finger. Then she eased it into Haeun's asshole.
"Nngh, n-not there...!"
Haeun reacted instantly. Soye only inserted the tip and slowly stirred it.
"Hyaaaaah!!!"
Haeun thrashed wildly. Her pussy pounded by my cock and her ass teased—she didn't know what to do with herself. Soye chuckled like it was fun and kept teasing her asshole slowly.
"Ah, it hurts, unnie, wait...!"
Soye's motions were far from serious anal training—just the tip of one finger, lightly prodding like petty mischief. Still, for the one enduring it, it wasn't simple; Haeun reacted intensely to every touch.
"Hngk, hyaht, haa, haaangh...!"
Her moans were fiercer than usual, and her pussy clenched even tighter. After tormenting her like that for a while, Soye grabbed my face with her other hand and turned it to her.
"Sejin-ah."
She stuck out her tongue, waiting. I did the same, and we slowly entwined them. Soon our lips met, tongues roaming each other's mouths, caressing.
"Mmph, slurp, chu...."
Soye kissed me while placing her hand on my ass, pushing and pulling like she was urging me not to stop. So I didn't. Even as I kissed Soye, my cock kept ravaging Haeun.
"Haa, haa, haangh...!"
Kissing one girl while fucking another. The thrill of this taboo setup...
I felt myself nearing climax, so I slowed my hips a bit. Soye sensed it like a ghost and whispered,
"Cum right away."
She kissed me again, her hands roaming my waist and abs, tickling lightly with her fingertips. Savoring her touch and kiss, I let go.
Spurt, spuuurt...!
"Nngh, ngh, haht, haaa, haang...!"
I kept pistoning through my orgasm, not stopping until I was fully spent.
"Hoo, hoo...."
When I pulled out of Haeun's pussy, the condom caught—Soye grabbed it and slid it off for me.
"Hng, you came a lot."
"'Cause... you were teasing me the whole time...."
Soye nodded at my words and started undressing. She shed her dress, bra, and panties in a flash, then pressed right up against me and whispered,
"My turn now."
"Yeah."
She glanced at Haeun and added softly,
"Do me raw."
She was so cute wanting that special treatment. She'd been scary all night, but finally, a glimpse of her usual self.
"Of course."
I smiled and laid her down next to Haeun.
