I Masturbated While Sucking My Best Friend's Pet Dog's Cock
Slip-slip-slip-slip—
Drawing on knowledge she'd picked up from some AV she'd watched once, Yeseo worked Mochi's cock diligently back and forth.
Mochi suckled hungrily at her breasts in return—greedily, like a starving little beast.
Slurp-slurp-slurp-slurp!
"Haaahn…!"
Every time he did, Yeseo felt a sharp, tingling jolt race through her enormous breasts. That sensation shot straight down into a throbbing heat in her lower belly, and thick, honey-like nectar began dripping from her petals onto the bathroom floor with soft little plip-plip sounds.
"Ahh…!"
She hadn't even been touched there, and still a thrilling spark lit up her sex. It was driving her insane.
She'd only come in here to masturbate—to somehow vent the lust boiling over inside her. And yet, somehow, Mochi had followed her into the bathroom.
In the end she'd let him watch her pee. And now here she was, squatting with her chest bare, jerking him off under the excuse of relieving his painfully hard little cock.
She didn't have to do any of this. There was no reason for the maknae of a top idol girl group to personally stroke and jack off a dog's erect dick.
She wasn't even his owner. If something was wrong with Mochi, all she had to do was tell Chaeyeon and let her handle it.
But instead—
Yeseo had pulled her tits out, wrapped her hand around Mochi's cock, and started stroking.
Why he'd gotten hard looking at her in the first place didn't even matter anymore. She was the one in heat. She was the one lusting after her best friend's pet dog. Unable to fight the excitement and the raw sexual need, she was the one willingly fondling his cock and doing filthy things with him.
Whether Mochi actually desired her was still unclear. This was nothing more than her working off her own lust.
But Yeseo couldn't admit that to herself.
Just make him cum already…!
What she was doing right now was helping a dog whose cock was painfully hard. She was absolutely not doing this because she wanted to.
Repeating that to herself, Yeseo sped up her strokes.
Slap-slap-slap-slap-slap-slap—
"Hnn… haaahn…."
The faster she went, the wetter her pussy became, love juices dripping steadily—but she forced herself not to care.
She'd never planned on masturbating while thinking about Mochi in the first place. The idea had been to finish her business, grab the phone she'd left in the room, come back to the bathroom, put on some porn, and get herself off.
The problem was that Mochi had followed her in.
The second she saw him standing there with his cock standing straight up and that big happy grin on his face, the memory slammed into her—this morning, when she'd masturbated thinking about Mochi's cock while burying her face in the scent clinging to his clothes.
And that was all it took. Yeseo lost her mind to pure lust.
Ahh! My hand moved on its own!
She felt her idle left hand drifting toward her sex without permission and jerked in surprise. Holding desire down by force was that hard.
"Haa… ha, haa…!"
She wanted relief. She wanted to rub her clit like crazy and masturbate until this piled-up need finally broke. She wanted to cum as sweetly as she had this morning.
That craving started taking over her head. And instinct—sexual need by another name—had a way of shattering even a professional female celebrity's stubborn reason.
Shlick-shlick-shlick-shlick!
"Hnn… shit… I can't take it anymore…!"
In the end, while her right hand kept working Mochi's cock hard back and forth, Yeseo stopped leaving her left hand idle. She brushed through her soft platinum pubic hair, then set her fingers on her little bean. Using her own slick as lube, she started circling her clit.
Flick! Flick! Flick! Flick! Flick!
"Ah—hnn…! Haaang…! Ahhng…!"
Every circle of her clit made her lower body twitch and shudder. The amount of juice leaking from inside her pussy spiked sharply, and the rush of pleasure hit so hard it felt like her mind might float straight off to paradise.
Mochi's long, thick meat rod drooled precum until it thoroughly soaked the right hand jerking him off.
"Heh-heh-heh!"
Slurp-slurp-slurp-slurp!
"Ahh, ahaaang…!"
Mochi kept alternating between her delicious-looking areolas and nipples, licking and sucking without pause. He looked every bit the vulgar, filthy little beast.
"Hnn, haang! There—it's sensitive… nnh-hnn!"
Yeseo could feel her breasts growing damp with Mochi's drool. At the same time she could feel her light-brown nipples standing fully erect and rock-hard.
"Aang. Nngh! Hnkk! Hnn, haaang!"
Suck-suck-suck-suck!
Feeling his tongue work both nipples, she kept letting out those cute little moans. Her upper body trembled nonstop on top of it.
Why does it feel this good just from having my nipples sucked…?!
Yeseo's sex drive had always been practically nonexistent, but she'd had her share of sexual curiosity. So she'd tried stimulating her nipples while masturbating before. It had done absolutely nothing for her—just felt ticklish—so she'd never touched them that way again.
But right now, with Mochi sucking on them, it was pure sexual pleasure. Just having him nurse on her nipples without even touching her clit felt like it could make her gush love juice and tip over the edge.
"Hahk! Haa! Haah, hnn, heuut!"
Squirt-squirt-squirt-squirt!
Even so, Yeseo circled her clit even faster.
Schlick-schlick-schlick-schlick!
Only a few minutes ago she'd been thinking how weird it was to do this with her friend's pet dog, wondering if she should stop right now. That was gone. She wanted to climax. She wanted to cum. She wanted an orgasm so hard it blanked her mind white.
What ruled Yeseo's head now wasn't her sharp brain—it was her pussy, driven mad with lust and drooling love juice all over itself.
Working both hands hard, she studied Mochi's cock up close. At a glance that big dick of his looked almost grotesque, but there was no denying it gave off an intensely filthy, erotic smell.
What would it feel like to put that in my mouth?
The thought had barely formed before Yeseo was already leaning in, pressing her peach-colored lips toward Mochi's cock.

Her soft lips parted wide and closed around the head with a wet little bite.
"Woof-woof!"
Mochi barked in pure delight. Yeseo kept rubbing her clit in a frenzy.
Slurp! Slurp! Slurp! Slurp! Slurp!
"Nnh! Hmmph, mmph, hmph!"
With his cock in her mouth, only muffled moans escaped. Carefully, Yeseo began licking around the glans.
"Keeeng!"
It must have been a sensitive spot—she felt Mochi flinch and shudder. If she kept working this place, she was sure he'd finally shoot his load.
With her right hand she stimulated near the root of his cock while her tongue licked the head from every angle.
"Nnhh… sluuurp… hnn, slurp…!"
Thick spit spilled from Yeseo's mouth, soaking Mochi's cock and filling the air with lewd wet sounds.
It tastes dirty… what the hell is this…
The more she licked and sucked his cock, the harder the pleasure hit. Her lower belly fluttered and pulsed as pussy juice sprayed out in little bursts. The sensation climbed higher and higher. Her slick, glistening cunt throbbed with electric sparks.
This explosive feeling was brand new—but she'd felt milder versions of something similar plenty of times. She was right on the edge of climax.
"Ahh, I'm—gonna cum…! Ah, aaaang…!"
Schlick-schlick-schlick-schlick-schlick-schlick!
Realizing it, Yeseo rubbed her clit even faster—and at last the orgasm hit, blanking her mind out completely.
"Kyaahk—kyaaahhhh……!!!"
Her back arched like a drawn bow. Her whole body shuddered and convulsed. The pleasure was so intense she pulled her mouth off Mochi's cock without thinking; the hand gripping him fell away on its own.
Then her pussy poured out thin love juice in a flooding rush.

"Ah, aah…! Kyaah-hnn…!"
The bathroom floor, which had been bone-dry, was soaked through with the juices she'd spilled.
She grabbed Mochi's cock again.
Slap-slap-slap-slap-slap-slap—!
And she didn't stop stroking. She could feel it getting bigger and harder in her hand.
And then—
"Wawawarf!!!"
Mochi barked like a wild beast and started to cum.
Throb-spurt! Throb-spurt!
"Kyaaaah…!"
Mochi's semen shot straight at Yeseo. Her platinum-blonde hair and pretty white face were filthy with his baby-batter cream.
Brrrrrt! Brrt!
Yeseo took Mochi's cum on her face without a word. Even through the aftershocks of her climax, curiosity got the better of her—she licked the semen off the corner of her mouth with her tongue.
"Ugh……."
It didn't taste particularly good, so she made a little suffering noise.
Before long Mochi's orgasm ended.
"Woof-woof!"
Looking thoroughly pleased with himself, Mochi stood back up on all four paws. Then he flopped down on the bathroom floor, wore an expression of pure bliss, and started licking his own body with the same tongue that had just been sucking on Yeseo's breasts.
Yeseo sat there dazed for a while before her mind finally came back online.
What the hell did you just do, Baek Yeseo?! Have you completely lost it…?!
It was the kind of situation that made a hollow laugh slip out on its own. With her lust spent, her head started working normally again.
What even was this situation? Confusing as it felt, it was pretty simple.
She had masturbated while sucking her best friend's pet dog's cock.
And the pleasure had been far, far better than anything she'd felt rubbing her clit that morning.
"What the hell… did I just do…!?"
The realization left her reeling—but it was already something she couldn't take back.
