The Winner of the Bet
Squish! Squish! Squish! Squish!
"Hah🤍 hah🤍 hah🤍 hah🤍 hah🤍"
Having already climaxed once, Dohee still wasn't satisfied. She started rolling her hips up and down all over again, masturbating with the toy buried in her ass.
"Heeeeh🤍 hah🤍 hah🤍🤍"
She was so thoroughly in heat that winning the bet barely registered anymore. Pleasure came first — chasing that good feeling mattered more than anything.
He'd seen her like this before, when he'd taken her at school. Dohee carried a more shameless nature than anyone, and her body hadn't forgotten the thrill of exposure. It only craved it more.
Even though they had the café to themselves, anyone could come upstairs at any moment — and she didn't care. Watching her work a dildo into her own anus was so filthy it left even Mom and Seohee stunned.
At the very least, when Mom or Seohee got ordered around by their own natures and ended up masturbating somewhere exposed, they still kept half an eye on their surroundings and held back a little. Dohee showed no trace of reason at all. She just moved her hips on pure instinct, tongue lolling, drool running down her chin — nothing but a bitch in heat.
"My asshole feels so gooood🤍🤍"
Squish! Squish! Squish! Squish!
As if even her clothes were too much, Dohee undid the buttons of her own shirt, freed her firm, bronze-toned breasts, and pinched her nipples hard, tugging them in a thoroughly masochistic display.
"Aaaah... Dohee🤍"
Mom, watching from beside her, was so shocked she'd completely forgotten she was supposed to get up and go to the bathroom. She just stared.
There was nothing maternal in that gaze. It was the lingering look one slut gives another — the eyes of a woman delighted to meet her own kind, drinking in a female even cheaper and more depraved than herself.
"Haaah🤍 Master, look at me🤍 Look at your sow Dohee masturbating for youuu🤍🤍"
Sensing his eyes on her, Dohee planted a foot up on the chair and dropped into a squat, working her hips again as if showing off that filthy, athletic body.
Until a moment ago, only her bare chest had been fully on display. Now her pussy was clearly visible — puffy and glistening with her own juices, twitching open. She'd gushed so much it had run all the way down her thighs, catching the light and making the whole picture even more obscene for him.
"Nngh-uuuh🤍🤍 Oppa watching me feels so gooood🤍🤍"
His gaze only wound her tighter. She grabbed both nipples at once, yanking and twisting them as she kept up that vulgar, sow-like masturbation.
"Looks like Dohee's going to win this one~ Mom can barely even stay like that, but Dohee's getting off like it's her pussy."
He said it as if he'd already lost, eyes still on Dohee. Their training levels looked about the same, but the difference in how hard they felt it was obvious. Mom could get plenty of pleasure from her ass by now — just not enough to thrash around and get off the way Dohee was.
"N-no — Mom's feeling it too, nngh🤍 Just like this🤍🤍"
Unwilling to lose to a line like that, Mom started bouncing up and down the same way Dohee was.
"Hngh🤍 See? Mom's feeling it in her asshole toooo🤍🤍"
She moved as if to prove she was right there with them, but she still couldn't go as rough as Dohee. An asshole was sensitive; force it too hard and you could tear something. It wasn't pain Mom was afraid of so much as damaging herself — she thought of her body as her son's property, and that made her careful.
And then the whole situation came apart.
Pop~
"Hah🤍 hah🤍 eh?"
The dildo Dohee had been slamming herself down on tore free of the chair.
"Nooo🤍🤍 Nngh-uuuh🤍 Dohee, wait — just a second🤍🤍"
Mom had been racing her, matching stroke for stroke — but the second she saw Dohee's toy fall, the original goal snapped back into focus. She clenched hard around the dildo and tried to force it out. Dohee's sphincter had been forged by track and field and real training; Mom had only done light exercise. It wasn't nearly enough.
"Heeeh🤍 Then I'm hitting the bathroom, Oppa~🤍"
Just from masturbating, Dohee could already tell she'd won. She stood up with the dildo still dangling from her. Most of it had slipped free; only the head was still gripped in her pussy, so it hung behind her like some bizarre tail.
Then, just to provoke Mom, she planted herself right in front of her and gave her hips a little shake. The dildo brushed Mom's face as it swung — pure humiliation.
"Nnnngh🤍 Dohee, you — haahng🤍"
Even while her own daughter degraded her, Mom still hadn't lost yet, so she kept trying to push the toy out. Her strength was fading, though. She could barely move her hips anymore.
"Haaaang🤍 Mom, I'm going now. Hehehe🤍🤍"
Ever since the last time she'd fucked Mom, Dohee had developed a habit of talking down to her whenever she got in heat. In the family's ordinary daily life Mom still sat at the top — but the moment he ruled as Master, Mom ranked lower than either Dohee or Seohee. She was used to being treated this way. She liked it.
"Be right back, Oppa~🤍"
Dohee headed for the bathroom with her chest still bare, breasts bouncing with every step. It was a dangerous place to look like that, but she was too far gone to care — she savored it, swaying the dildo behind her like a wagging tail as she went in. A moment later she came back out and walked straight toward them.
It was an embarrassing, shameful sight for anyone else to see, and Dohee felt that shame — she just converted the feeling straight into pleasure.
She's had so much exhibition training that being exposed barely even bothers her anymore.
Wandering around a public place looking the way Dohee did could blow up into a serious problem in an instant. Going forward, he decided, he'd have to keep a tighter leash on that part of her training. He watched her the whole time.
"Haaah~ ang🤍 Mom — a pre.sent. for you🤍"
Dohee shoved her ass toward Mom, bent at the waist, spread herself open with both hands, and pushed.
Pop~
The last of the dildo slipped free and dropped onto Mom's lap. The thing was completely soaked. The sight of it only wound Mom tighter; instead of stopping, she started masturbating even harder.
"Hahk🤍 You just gave Mom the dildo that was in your asshoole🤍🤍"
Mom tried to sound like she was scolding her, but she was still working her hips as she said it. The words had no force at all.
Watching her, Dohee must have climaxed again — she was drooling fresh pussy juice onto the floor, face locked in an ahegao.
Anyone who knew the cool, blunt Dohee from ordinary life would have sworn this was a different person entirely, she looked that cheap.
"Ah~ I lost. Well, the bet's over, so let's head home for now."
With the contest decided, they cleaned themselves up, got dressed, and went downstairs.
"The coffee was great."
"Yes — please come again."
They'd been loud enough that the employee had clearly heard everything; her face was bright red. She would have been well within her rights to stop them, but she never once intervened — maybe she'd been enjoying it too. Still, he left her a tip of about two hundred thousand won as hush money, and luckily nothing came of it.
Upstairs, the floor was still slick with everything Mom and Dohee had gushed. The tip covered cleanup too. The employee who went up to mop was stunned — and the fact that she'd quietly taken the CCTV footage home without telling the manager, to use as material for her own private sessions, remained her little secret.
By the time they got home, the anal training had left Mom and Dohee thoroughly worn out. There was no point trying anything more in that state, and it was late besides. They showered, piled into Mom's room together, and fell asleep.
The next day
When morning came, Mom and Dohee were still too exhausted to get up the way they usually did. He and Seohee woke first and went out to the living room.
He sat on the sofa. Seohee, naked in her slave's place, knelt before him with a faint flush in her cheeks and looked up at him.
"Right..... A promise is a promise. I should keep it, shouldn't I?"
"Yes..... Thank you🤍"
In the end, Dohee had beaten Mom — which meant Seohee had won her bet with him. He still owed her the victory prize she'd named, but he couldn't give it to her yet. For now, he needed to be clear with her.
"But are you really okay with that? It could cause problems later....."
When Mom and Dohee had been mid-training and the atmosphere was running hot, he'd agreed without thinking. Now that he actually sat with what Seohee wanted as her prize, he had to admit it could get messy. It left him uneasy.
"Yeah....... It's fine.......... But........ if Oppa doesn't want to, we don't have to....."
She'd won, so of course she wanted her reward as promised — but she was still his slave first. If he refused, she would accept it in the end. Even so, the way she looked faintly dejected (still no real change in her expression, of course) made his resolve soften.
"No. A promise is a promise. Once I'm ready, I'll call you."
"Okay🤍 Thank you....... Master."
Seohee bowed to him, offering her thanks not as a little sister but as a slave.
"That aside — you know what comes next, right?"
"Yes🤍....... Seohee will serve you..... with her asshole-pussy🤍"
He'd spent all of yesterday training and opening Mom's and Dohee's asses, and barely touched Seohee's at all. It wasn't that she hadn't enjoyed any of it — but she was a masochist, and by now she had to be aching with unmet need.
All day long, Mom and Dohee had been trained and developed while she'd been left out. Today, as a kind of compensation, he fully intended to put Seohee through plenty of training of her own.
