So This Is What You Put in Your Pussy

What the hell kind of situation was this?

Baek Yeseo had barged in out of nowhere.

Just moments ago, according to Roselina, she'd been peeping on us having sex, masturbating herself to climax and spraying her squirting juices everywhere. Curious what a freshly orgasming blonde idol beauty looked like, I'd shuffled backward with my cock still buried in Eun Chaeyeon's pussy to get a better look — and that was how I'd ended up here.

"Ahh…"

Eun Chaeyeon wore a face of pure panic. Her eyes darted frantically between my face and Baek Yeseo's, utterly at a loss. Then her whole body started trembling.

Getting caught by your best friend mid-sex with your pet dog wasn't exactly something you could just brush off cool and casual. Embarrassing. Mortifying. The kind of thing that felt like social suicide.

But don't worry, Chaeyeon.

Yeseo here was one of my cock-sleeves too. A dedicated living onahole who'd start whining the second I shoved it in. I had no idea why she was acting like this all of a sudden, but still.

Conveniently enough, my cock was free to slip out.

"Woof."

Schluuuck!

"Kyaah!"

The moment I eased my cock free of that springy pussy, Eun Chaeyeon threw her head back with a filthy moan. Looked like she'd cum lightly just from that. She gasped in shock a second later and hastily clapped both hands over her mouth.

Baek Yeseo snorted at the sight.

"God, look at you making a complete spectacle of yourself."

Contempt twisted her face. Her gaze on Eun Chaeyeon was ice-cold.

"Ye-Yeseo, that… th-this isn't what it l-looks like…"

Eun Chaeyeon was still shaking as she tried to force the words out, but Baek Yeseo just folded her arms and sneered.

"What exactly are you trying to explain, Chaeyeon? You were fucking your pet dog. That's an established fact. Is there seriously anything left to clarify here?"

At that cold, blunt question, Eun Chaeyeon hiccupped and clamped her mouth shut.

And me?

What is this, am I supposed to break out the popcorn?

Damage control? Please. Dopamine was popping off like fireworks in the middle of this total catastrophe, and I was living for it.

Of all the people to crash the party — Baek Yeseo. But why was she looking at Eun Chaeyeon like she was disgusting? She was a total pervert who'd happily mated with me herself.

This was definitely entertaining. I just hadn't seen it coming at all. I'd figured she'd quietly leave. Never in a million years did I expect one of my meat-slaves — a girl who'd just thoroughly fucked a male dog like me — to turn around, look at another meat-slave, and start sneering about how anyone could possibly have sex with me.

I was still reeling from the sheer absurdity of it when a thought suddenly flashed through my head.

Wait. Is this a threesome setup?

Think about it. Why would Baek Yeseo go out of her way to pull a stunt like this? Why glare at Eun Chaeyeon with that much venom?

She's jealous, isn't she?

Pissed that I was fucking Eun Chaeyeon instead of her. Taking it out on her for no good reason. And maybe, after that, she was planning to fuck me herself.

Was that reading too much into it? Peak self-absorbed delusion?

That was when Roselina chimed in with a bright smile.

What? Are you serious?!

I studied Baek Yeseo's face more carefully. Sure enough, the rims of her eyes were flushed red. So she really had been crying over me.

Okay… why, though?

I was starting to feel a little ridiculous. What was she, some defeated love-comedy heroine? I was just a dog. She'd watched me fuck her best friend, spun up a whole storm of negative fantasies, cried her eyes out, and jerked off over it?

Hmm… maybe it's not that weird.

Sex with me must have felt that good. Maybe, just like Eun Chaeyeon, she'd started seeing me as a male — and fallen for me.

Baek Yeseo. I'd figured a girl with a low sex drive would be a tough nut to crack, but she was this easy a conquest? Idols really weren't anything special.

I smiled to myself at the thought.

Roselina promptly fed me Baek Yeseo's arousal reading.

Her arousal was sitting at a full 125 percent. Even after masturbating hard enough to squirt like a fountain, her hunger still hadn't settled — she was itching to fuck me. We might end up in a threesome any second now.

Baek Yeseo finally pulled her gaze off the still-floundering Eun Chaeyeon and sat down on the bed.

"You know you're disgusting, right, Chaeyeon? How do you even have sex with your own pet dog? And you know that's animal abuse, right? Did Mochi even want to fuck you?"

"No… but… I got raped by Mochi…"

"Wh-what?"

Baek Yeseo had been putting on a whole performance, needling Eun Chaeyeon for all she was worth — but the mask cracked for a second. She blurted it out in genuine shock, then whipped her head toward me. Her expression was distinctly uneasy. Probably thinking I really might have ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠done it. Then again, she'd been the one who jumped me first, so maybe she was just feeling guilty.

After a brief blank stare, Baek Yeseo cleared her throat and fixed Eun Chaeyeon with another glare.

"There's a limit to how much you can lie. You seduced him, didn't you? Did you spray some perfume male dogs go crazy for on your pussy or something?"

"N-no I did not…?!"

"I'm honestly amazed. If you were that hard up for sex, you could've just hired a male escort. Instead you end up fucking your own pet dog? What's so great about it, anyway?"

She kept insulting Eun Chaeyeon — and all the while, she was inching closer to me. Her eyes had gone incredibly seductive.

I had a pretty good idea what was coming next. I flopped onto my back so she could get at my limp cock nice and easy.

A moment later—

"Hup…!"

Grab!

Baek Yeseo grinned playfully and clamped her hand around my dick. The soft touch of a famous girl-group maknae's palm sent my hypersensitive cock swelling bigger by the second.

"W-wait! What are you doing, Yeseo?!"

Eun Chaeyeon went wide-eyed and shouted at the sudden move. Gone was the timid, guilty tone from before — her voice was pure anger now.

"Pfft… why so worked up, Chaeyeon?"

Baek Yeseo smirked at her, gently stroking and teasing my cock with a focus on the head. My monster dick snapped to full mast under her touch. Then she started pumping it with warm, careful strokes.

Slip, slip, slip, slip!

"Wooorl—"

The electric sensation wrenched a sound out of me before I could stop it.

This crazy pervert Baek Yeseo. She was seriously planning to jump me right here?

Well. I appreciated the enthusiasm. Thanks to her, the threesome angle was locked in.

"Upsie."

Baek Yeseo let go of my cock for a second and stripped off her pajama top in one smooth motion. Her G-cup breasts bounced and jiggled, full and firm. Smaller than Eun Chaeyeon's, sure, but still a serious pair of tits.

The color of her nipples. The size of her areolae. Everything about them was different from Eun Chaeyeon's, and I liked the variety. If Eun Chaeyeon's breasts had a clean, refined beauty, Baek Yeseo's had a vulgar edge that made them filthier somehow. Either way, there was no ranking them — both were incredible. I just hadn't gotten to look at Baek Yeseo's tits as often, so right now they were pulling me in harder.

Watching this blonde, blue-eyed beauty with her breasts fully bare and her pajama shorts soaked through with pussy juice sent a fresh surge of heat through me.

Baek Yeseo kept diligently jerking my cock, still slick and sticky with Eun Chaeyeon's lewd juices.

Slap slap slap ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠slap slap slap!

"Mmm… does sticking something like this in your pussy feel that good?"

Even as she said it, she kept throwing sneers Eun Chaeyeon's way. Her hand was already sticky with the cunt juice Eun Chaeyeon had gushed all over me.

"Wow… look how thick Chaeyeon's love juices are."

"!!!"

Eun Chaeyeon's face went scarlet. Having her best friend say something like that to her was a first, and the shame of it made her bite down hard on her lower lip.

But then her expression twisted into pure fury. After taking nonstop verbal abuse, her pride had to be thoroughly shredded by now. Nothing ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠strange about that. She locked eyes on Baek Yeseo.

"Hey… Mochi doesn't like that."

Me? I didn't mind at all, though?

Was this bitch getting jealous all of a sudden? She looked like she was tasting a little of whatever Baek Yeseo had felt earlier during her defeated masturbation session.

"Woo-woo!"

I beamed and thrust my cock toward Baek Yeseo, making it crystal clear I was enjoying myself.

"Ahaha! This is fun!"

Slip slip slip slip!

Baek Yeseo grinned and sped up her handjob.

"M-Mochi?!"

Eun Chaeyeon realized I was actively enjoying Baek Yeseo's handjob and crumpled into despair. The way her pupils trembled with sheer disbelief was a sight to behold.

Baek Yeseo smiled brightly, practically radiating superiority. It was a dangerously seductive smile — like a nine-tailed fox come to devour a male's essence — and it was incredibly hot.

Feels like the tables just turned.

Just a little while ago, Baek Yeseo had been the one crying and jerking off in defeat. Now Eun Chaeyeon looked like she was about to burst into tears, while Baek Yeseo was flushed with excitement, tenderly working my cock.

Shlick shlick shlick shlick!

Then, all at once, she stopped stroking. Smiling sweetly, she tapped my cockhead with her fingertips and looked straight at Eun Chaeyeon.

"So… this is what you put in your pussy, huh?"

Still talking like this was her first dirty act with me, Baek Yeseo peeled off her pants and panties.

Rustle.

"Huh…?"

Only then did Eun Chaeyeon realize Baek Yeseo's panties and pants were completely soaked through with pussy juice. She flinched in shock.

While she was still staring in disbelief, Baek Yeseo was already pressing her pretty pussy — crowned with a modest jungle of platinum-blonde pubic hair — right up against my cock.

"Mind if I try putting it in too?"

"A-ah! Wait a second!"

Seeing Baek Yeseo about to sink onto my cock, Eun Chaeyeon scrambled to get up off the bed —

"Nnh…!"

— only to collapse back down with a moan. The rough sex earlier had left her too wrecked to stand. She ended up sprawled in a catlike pose on all fours, my cum dribbling out of her pussy and soaking into the sheets. The sight was obscenely erotic.

Baek Yeseo smirked at the view, then lowered her hips and started taking me in.

Schluuurp!

Schluuuuurp!

"Aang…!!!"

Baek Yeseo swallowed my cock to the root with her pussy and let out a filthy cry of pleasure. Then she started rocking her hips back and forth, grinding her clit as she began to ride.

Squish squish squish squish squish!

"Ahh! Ahhnn! Kyaahng! Kyaaahng!"

Slap slap slap slap slap!

Pussy juice spraying with every bounce, Baek Yeseo kept riding me cowgirl-style.

"Ah… nnh…"

Still whimpering from the aftershocks of our rough fuck, Eun Chaeyeon could only watch the whole thing unfold with a face on the verge of tears.
