Almost Fully Developed in a Single Day
Gurgle…
"Hngh… hahh… Son, please, let Mom use the bathroom… hnnngh!!"
With the anal plug locked in place, the strength drained from her ass enough that she couldn't simply dump out the white liquid packed inside her—but that didn't mean the agony had lessened one bit.
She had never been touched back there before. Every sensation flooding through her now was brand new, and cold sweat beaded across her skin.
"Not yet."
"Knnngh!!! But…"
Mom was suffering so badly she couldn't even spare a thought for the fact that an anal plug had been forced into her for the sake of training her hole. At the same time, there was no way she could pull the plug free without using her hands—so no matter how much the tension left her rear, she still couldn't relieve herself.
Every so often her strength failed her, and still nothing came out. Doing something like that right in front of me would have been mortifying beyond measure. Even if it was only enema fluid, emptying it out through her ass in front of another person was an act of extreme humiliation for any woman—for any human being.
"Alright then. Entertain me with this, and I'll let you go."
I still needed to wait until Mom's asshole got used to the thick anal plug, and just standing around was boring, so I fixed a dildo firmly to the floor.
Seeing it, Mom dragged her trembling body forward, spread her legs wide in a lewd squat, lined her pussy up with the tip of the dildo, and turned a shaky smile toward me. Watching her grin through the cold sweat just to please me, I smirked right back at her with open contempt.
"Haahn~ 🤍"
At that dismissive smile, Mom's body jerked; true to her masochistic nature, fresh juices began dripping from her cunt all over again.
"From now on… hnnngh 🤍 …Mom will pleasure her son with her pussy… 🤍"
Squelch!!
"Ooooh!! 🤍🤍"
Her soaked pussy swallowed the dildo without resistance as she sank her hips down. From all the slave training, her hands went automatically behind her head while her face twisted into a mindless ahegao—the perfect picture of a filthy sow.
Next to Dohee, who was already squealing like a pig, Mom's beastly cries completed the image of a thoroughly degraded mother-and-daughter pair of sows.
Squelch! Squelch! Squelch! Squelch!
"Ooh!! 🤍 My pussy feels so good!! 🤍 But knnnngh 🤍🤍"
Between my mocking smile and the sheer shame of her situation, Mom got even more aroused. Pussy juice poured down her thighs as she bounced up and down, coating the dildo and leaving sticky trails all over the floor.
Still, the pain knifing through her belly kept her from thrashing as wantonly as usual; her movements stayed a little slow. Even sitting still hurt, and now she was masturbating on top of it—her face contorted in agony, yet the moment her eyes met mine she forced on the brightest smile she could manage.
"Moving that slow is no fun at all."
Smack!!! Smack!!! Smack!!! Smack!!!
"Knnngh!!! I'm sorry! 🤍🤍 I'll move harder—ooooh 🤍🤍"
I stepped in close and slapped her swaying H-cup breasts from the side as they bounced with every stroke. A feral cry tore out of her throat, and just like that she started working her hips the way she always did.
"Whoops—can't let that slip out~"
"Hnnnnngh!!!! 🤍 Th-thank you 🤍🤍"
As her strength began to fail, the anal plug started easing its way free. I caught it and shoved it straight back in.
Losing the chance to make things even a little easier only pushed Mom deeper into the humiliation—and deeper into heat.
"Ooooooh! 🤍🤍"
Pssshhhh~ 🤍
Still riding the dildo, Mom climaxed with her tongue hanging out in a full ahegao, thrusting her pussy forward as a gush of fluid sprayed out of her.
"Heh!! Nice. That was fun. You're allowed to go now."
"Haaahh 🤍🤍 Th-thank you 🤍"
Her asshole was finally stretched enough, so I gave her permission—but all Mom could do was thank me for granting it.
"Alright then…… go take your shit."
Pop~~
"Huh?! 🤍 W-wait—knnnnngh 🤍🤍🤍"
Without another word I yanked the anal plug straight out of her ass. Panicked, Mom clenched hard to keep from leaking, then crawled toward the bathroom on trembling arms.
"Haa… haa… finally… 🤍"
A look of pure relief bloomed across her face at the thought of escaping the pain—until I tugged on her leash. She glanced up at me, puzzled.
"Not there. You're going over there~"
I pointed not at the toilet, but at the bathroom floor itself. Then I dragged Seohee and Dohee along with us.
"Aaaah… th-this is too much 🤍"
Mom crouched on the bathroom tiles, legs spread wide, staring up at us. Me, Seohee, and Dohee—who looked every bit the filthy sow herself—all watching as she prepared to empty the liquid filling her belly.
It was something she had never done before, an act that threw every scrap of human dignity straight into the dirt. And yet a humiliating smile was already spreading across Mom's face.
In her head she knew it was shameful, degrading, something she should hate—but her masochistic body was dripping with anticipation, pussy juice trailing down as if it couldn't wait to let go.
"Alright then…… go on, Mom. Shit."
"Aaah… aaaaaah 🤍🤍"
She had held it past her limit, and my command was the final push. Mom simply let go, dumping the white fluid filling her guts right there in front of all of us.
Even in that mortifying moment, a radiant smile lit her face. Listening to our laughter, she came hard from her pussy.
"Hah 🤍 hah 🤍 hah 🤍 Mom just… haaaaah 🤍🤍"
Watching their mother empty herself was a shock for both Dohee and Seohee. Even so, what they felt wasn't disgust—it was envy. For masochists like them, humiliation wasn't simple shame; it was shameful arousal. Both of their pussies were already soaking wet.
Bzzzzz
"Hnn 🤍 knngh 🤍"
Dohee, still mid-training, had anal beads in her ass and a whirring dildo in her pussy. She was completely in heat.
"We should…… hurry up too 🤍"
Excited by Oppa's methods, Seohee grabbed Dohee's leash and led her out of the bathroom toward the living room.
"Unnie…… I'm going to develop you…… with this."
What Seohee pulled out was a set of anal beads thicker than the ones already inside Dohee.
Bzzzzz
"No hands…… pull them out."
"Nngh… yes 🤍"
At Seohee's demand, Dohee reached back, spread her own ass cheeks wide, and began pushing the beads out one by one.
"Hnnngh 🤍 knnngh 🤍🤍🤍"
Pop~ Pop~
As each bead slipped free, the sensation of voiding sent fresh pussy juice streaming down Dohee's thighs. At last she pushed every last bead out of her hole.
"Heeeeh 🤍🤍"
Already somewhat trained, Dohee's asshole stayed open and twitching once the beads were gone. Without the slightest hesitation, Seohee shoved the thicker set of beads straight into her sister's hole.
"Ooooooh!! 🤍🤍"
Dohee moaned with raw excitement at being trained by her little sister. The thicker beads went in without much trouble.
The size wasn't dramatically different from before—but there was one crucial difference.
Click.
Bzzzzzzz
"Ogoooh—nnghoooh?!?!! 🤍🤍"
These weren't ordinary beads. They were motorized, writhing and twisting inside Dohee's asshole like they meant to wreck it.
Dohee was the type who could climax from nothing more than insertion. The moving beads dragged her into territory she had never known—pleasure that made Seohee's earlier tongue-work feel like nothing. She could only sob and writhe.
"Gnnnoooh 🤍🤍🤍"
On all fours with her ass shoved high, Dohee trembled under the brand-new pleasure flooding her rear. Her inverted nipples stood stiff and hard, and pussy juice poured freely, staining the floor.
"Unnie…… you look so good 🤍"
Seohee watched her sister and slipped into the dildo pants she had used before. Lost in the pleasure, Dohee couldn't move an inch. Seohee stepped in and yanked the beads out of her sister's ass without a second thought.
"Ogoooooong?!?! 🤍🤍"
The sudden emptiness made Dohee's hips buck hard as she came; her eyes rolled back and her body went still. Seohee pressed the dildo to the entrance of Dohee's asshole and drove it straight in.
"Here I go…… Unnie 🤍"
Squelch!!
"Oooong?!! 🤍🤍 A c-cock—iii 🤍🤍🤍"
Even though it was only a dildo, Dohee took it for a real cock. She howled like a sow in heat, drowning in sensation, climaxing over and over without end.
And so Seohee and I each finished developing Mom's and Dohee's assholes. After a short break, we gathered again in the living room to check the results of our little wager.
Seohee and I were dressed normally. Mom wore a tight one-piece that clung to every curve. Dohee had put on a miniskirt she almost never wore, paired with a shirt.
"Both of you. Spread."
At my order they turned around and pulled their assholes wide open. Without hesitation, Seohee and I shoved dildos straight into their holes.
"Haaaaaahn 🤍🤍"
