The Females' Conversation
"Hmm... I guess I should go peek after all."
He'd told his mother and Boyeon to wait upstairs after they washed up, but curiosity was getting the better of him. Just how obscene would it be to see two women—two bitches—showering together? Suggesting he join them felt like bad timing, so he decided to sneak a look instead. He slipped quietly out of the room. If he got caught peeking, Boyeon would no doubt tease him with that mischievous grin of hers, so he crept silently to the bathroom door.
The door was left ajar, and inside, his mother and Boyeon were showering. The sight of the two naked bitches under the spray was intensely lewd.
Gulp... He watched quietly, careful not to get caught, when their conversation drifted out.
(Boyeon)
(Jeong-ah)
"Ma'am, when did you... become Sunbae-oppa's female pig♥?"
"About a week before summer break ended. I was sleeping, and he raped me."
"Ehhh!? While you were asleep, and he did that♥?"
Their conversation sure isn't normal...
They were his bitch slaves, sure, but they'd only met today, and already they looked thick as thieves.
Well, after what we did together, they were bound to bond mentally...
They'd even drunk his piss together—no secrets left to hide, and that shared sense of depravity had made them fast friends.
"If we'd lived together, I bet I'd have gotten the same treatment from Sunbae-oppa... oooh♥"
"If you'd been born my daughter instead, you might've become my son's female milk cow even faster than me♥"
"Y-your daughter as a female milk cow♥ Just imagining it has my pussy leaking♥"
The topic was insane, but he was the one who'd twisted them that way. Nothing to say about it, really. If anything, it was turning him on more—score.
A little sister, huh...
As an only child, he'd never had siblings, so he couldn't quite picture it. He remembered friends with brothers or sisters complaining sometimes—they didn't seem thrilled about it.
A milk cow little sister... sounds pretty damn good? But if she was like Boyeon, yeah, he'd be all in.
"Ma'am, how far along is your... training?♥"
"Pussy and ass go without saying... right now, my piss hole's almost fully developed too."
"Whaaat!? You develop that too!?"
"If my son wants it♥"
"Th-then maybe me too♥..."
"Not sure yet, but if my son wants it, then of course this hole needs developing too."
Squelch squelch squelch
"Ah♥ Ooht♥ Feels so weird♥"
He had no plans to go that far with Boyeon yet, but she didn't seem to mind—flashing a lewd smile as his mother toyed with her piss hole, her face full of pleasure.
"Becoming my son's flesh slave means completely abandoning yourself♥ If you don't have that resolve, better quit here♥"
"I-I'm resolved♥ Ooht♥"
"Hehehe♥ With the same maso tendencies as me, you'll develop quick♥"
"Please take good care of me♥"
Boyeon, already committed to life as his female milk cow, beamed happily at his mother's words.
"But this hole's never been touched before, right?"
Squelch
"Ah♥ Y-yes♥"
His mother prodded Boyeon's anus lightly as she spoke.
"Hmm... looks like this needs developing right away."
Squelch squelch squelch squelch squelch
"S-suddenly♥ Ooht♥ Haaang♥"
"I'll get permission from my son, so wait just a sec."
"Yesss♥"
His mother prioritized his opinion over Boyeon's, acting like it was the natural order. Boyeon blushed and nodded along.
Ah! She's coming...
"I'm going to develop Boyeon's anus like a pussy—may I have permission?"
"Uh... yeah... sure."
"Understood."
He'd spotted her coming and tried to bolt back upstairs, but she just addressed him casually, like it was no big deal. She clearly knew he'd been peeking, but her calm reaction left him feeling awkward.
"Then I'll prepare the same tools I used."
"Got it... keep it light today."
"Understood♥"
With permission granted, his mother fetched the tools. Caught red-handed, he just stood there brazenly peeking from the bathroom door.
"Haaang♥ H-how do you even develop it♥ I've never done anything back there♥"
Boyeon waited in the bathroom, fidgeting—anxious 1 part, excited 9 parts. One shocking thing after another today, and now anal training? She was thrilled beyond control.
"I've brought the enema tools first."
"Haa♥... Oooh... Y-yes♥"
The word "enema" turned Boyeon's face beet red with shame. But at the sight of the huge syringe and pink liquid, she swallowed hard, her lips curling up. A true maso like his mother, she turned most humiliations into pleasure. She was actually looking forward to the enema.
"Then get on all fours, ass facing me."
"Yes♥"
She obeyed his mother's command meekly, raising her ass high. Pussy and anus fully exposed in the shameful pose, but she held it perfectly, even spreading her cheeks herself.
"Oh my. Such a pretty pink."
"Eep♥ D-don't stare so much, it's embarrassing♥"
"Feeling shame is good, but you'll be seeing it a lot, so get used to it."
"A lot♥... Yes, Ma'am♥"
Boyeon often acted cheeky in front of him, but she was on her best behavior with his mother. (...Though that pose wasn't exactly "proper"—her tone and caution were obvious to him.)
"Hmm... Today I'll just loosen it enough for my son to use, but you'll need to develop it more on your own later."
"Yes♥"
Hearing she'd have to train her own anus, Boyeon dripped pussy juice like crazy.
"Then I'm putting it in—hold it well."
Sluuuurp
"Hnnnngh♥ C-cold♥"
"Not much for a first time, but to get clean, we'll do two more."
"U-understood♥"
She jolted at the cold liquid filling her guts but held her pose—no complaints.
In a bit... gulp
Seeing Boyeon clean her ass for him made his dick even harder.
Time to head up. They'd be coming soon, so he quietly slipped upstairs to wait.
......................
"All done now."
"Haa♥... Eep♥..."
Three rounds of liquid in her belly left a slight ache.
This is way more embarrassing than I thought, suda♥
Boyeon trembled as his mother made her spread her anus and filled her up. Mortifying, sure—but the arousal outweighed it.
Scored points with Ma'am♥
She smirked inwardly, pleased that his mother seemed to like her. Maso slave or not, Ma'am was still Ma'am—better to stay on her good side for the future. She minded her speech and went along with whatever Ma'am suggested.
"Let's clean up and head up."
"But when do I... let it out♥... Ooht♥"
"You'll find out when we get upstairs."
"Haa♥... Haa♥... Yes♥"
Ma'am hadn't put in much, but as time passed, the discomfort grew. First time and all.
Feels like it's expanding in my gut♥
Not unbearable, but the urge to shit was humiliating. She knew it was to clean for him, but the sensation still flushed her face.
"Alright, let's go."
"Ah... Yes!♥"
She wanted to rush to the toilet, expel it, clean up, and go to Sunbae-oppa—but no, they headed to a room together.
"Wooow♥"
The room was littered with lewd toys on one side, and the bed was huge—room for four easily.
"It used to be my room, but now it's my son's sex room♥"
"No wonder it smells so... haaa♥..."
Thick with the scent of copulation, the room made her body heat up on its own.
"You're here?"
"Yes, son♥ Both your bitches are squeaky clean—please defile us again as you like♥"
"P-please defile us♥"
She mimicked Ma'am's dogeza greeting.
This pose presses on my belly—hurts♥
With her gut slightly bloated from the liquid, the pressure hurt, but she had no choice.
"And the milk cow's shithole is enema'd and ready for use."
"Good work, Mom."
Squish
"Hnngh♥ Th-thank you♥"
Ma'am trembled in joy at having her head stepped on. Watching, Boyeon felt jealous—reminding herself she was no different, just another maso bitch.
"How much longer?"
"Probably 30 more minutes♥ But if she shakes her hips to heat up, it could be ready in 10♥"
Boyeon tensed, watching their cryptic exchange.
"Yeah? While I use Mom, Boyeon, masturbate with this."
Thud He stuck a huge dildo to the floor.
"Yes, understood♥"
No questions, no curiosity.
Squelch
"Hnnnnght♥ G-gonna start masturbating like this suda♥♥"
Squelch squelch squelch squelch
Just squatting vulgarly and pistoning on it per his command.
Masturbating in front of Sunbae-oppa and Ma'am—too exciting♥
With her belly full of mystery liquid, she started shaking her hips. No clue what came next...
