Unbearable Shame
Mom was unpacking the yoga mat that had just been delivered.
"Mom, you got a second?"
"Of course, Master."
She stood and followed me into the master bedroom.
"Mom, Sua seems a little off to me."
"Why...?"
She asked, looking puzzled.
"It's like... I don't know how to put it. She gives off this feeling that she's been living all bottled up."
"Bottled up...? Hmm, I'm not sure I see it. Sua does her own thing, studies hard, tends to be the quiet type..."
"Has she been like that since the very first time you met her?"
"Yes. Same then as she is now."
The way the answer came out without a second's hesitation made it clear she'd never noticed anything unusual.
"Still feels weird, though..."
"Shall I keep an eye on her?"
"No, no, it's fine. I was probably just being sensitive."
I was sure of it—there was something hidden about Sua.
"Oh, and I want those grapes now."
"Shall I take them out myself?"
Mom asked, pointing at her panties.
"I'll get them myself."
Without ceremony, I pulled the grapes out of Mom's pussy.
"Ahng..."
She made a soft sound at the foreign sensation, clearly uncomfortable.
"They're warm..."
Three grapes from Mom's most intimate place. They should have dried out by now, but they were still slick and glossy with her fluids.
"Still wet?"
"Thinking about the grapes being inside me... I guess I got wet..."
"Thanks. They're good."
I chewed the grapes as I spoke.
"I'm glad."
Mom went back out and started her yoga. Watching her do it in nothing but her underwear was pretty damn hot.
Every time her eyes met mine from outside the room, she didn't look embarrassed at all—if anything, she held her poses as if inviting me to look longer. It got me hard all over again.
"Geez... I've never seen that thing not standing at attention."
Sujeong, wandering through the house, spotted me and tossed out a scolding remark.
"Sujeong, then do something about it."
"W-what?"
"Settle this thing down for me."
"Right... here?"
"What's the problem? You're all my slaves, aren't you?"
"Th-that's true, but..."
The bold front she'd been putting on earlier was gone without a trace; the girl standing in front of me now was nothing but a flustered, embarrassed teenager.
Whether she was embarrassed or not, I pulled my cock out.
"Wha...?"
She'd only ever seen the tent. Confronted with the real thing for the first time, Sujeong stared at my cock in blank disbelief.
"Big, right?"
"...It's enormous..."
"Figured I'd use this chance to completely fix big sis's attitude."
"But... if we're really going to do it in the room... maybe we should at least go to a room..."
"Take one step back and I'll think about it."
Which was my way of saying I wasn't going to finish her with just one stroke of luck.
She sat down cross-legged, but the height didn't match my cock, so she shifted onto her knees instead.
"Puhaha~ That's actually hilarious. What, you try to suck a cock while sitting like some nobleman?"
"I-I... I don't know!!"
Even so, she was fretting uselessly over whether Mom might hear.
"Alright, suck. You know not to let your teeth touch, right?"
"I don't know..."
When she got flustered, she had a habit of saying she didn't know.
Sujeong took only the head between her lips and sucked with little suck, suck sounds.
"Ugh... are you kidding me right now?"
I grabbed the back of her head and shoved my cock all the way down her throat.
"Ghk... agh...!... ca... can't...!!!... khek!!!!... ehk!!!"
At the sudden battering of my cock, she thrashed and slapped at my thighs.
My cock rode the wall of her throat a little deeper.
For a first time, this should be enough.
I pulled back out.
"Sis, don't just suck the head. Get as much of it into your mouth as you can and suck. Got it?"
"Cough... e-even so... ugh... this is..."
"Suck it again."
Her face was bright red, tears welling in her eyes as she glared up at me.
She shuffled forward on her knees until she was in front of me again. This time she took me as deep as she could manage.
Even then she couldn't focus on my cock, eyes darting around, checking whether anyone was coming.
"Mom~!"
I called for Mom again.
"...Y-yes, Master~"
From the far room, Mom answered and came out.
Startled by the sound of her voice, Sujeong tried to yank my cock out of her mouth at once.
"Ghh...!... nghh!!"
But I lightly pressed down on her head with my hand and stopped her.
"Haa... haa... You called for me?"
Mom came into the living room slightly damp with sweat from her yoga.
And her eyes met Sujeong's—with my cock still in her daughter's mouth.
It was the first time the two of them had come face to face in a situation this awkward.
Sujeong tried to pull free, but a light pressure from my hand on her head was more than enough to pin her in place.
The moment her eyes locked with Mom's, I felt the strength drain from her throat.
"Ah~ Sis wouldn't suck my cock properly because Mom was around. You've seen it now, right?"
Mom held Sujeong's gaze for a moment, then deliberately looked away at the floor.
Sujeong did the same, my cock still filling her mouth as she forced herself to look anywhere else.
"...Yes. I saw."
That was Mom's answer. Even with her daughter holding her son's cock in her mouth, she had no intention of intervening.
I couldn't read her expression, but one thing was certain.
Mom had already stepped fully across the line into complete slavery.
"Mom, show her how it's done."
"M-me?"
"Yeah. As her mother, you should demonstrate."
Mom quietly approached, knelt beside Sujeong, and waited.
"...Pah!"
My cock slipped free of Sujeong's mouth.
Slick with spit, it was immediately wrapped by Mom's lips.
Hwaup—
Sujeong's eyes went round as saucers watching her.
"...Mom..."
Mom didn't answer. She simply and diligently sucked my cock in silence.
Churp... churrup... ghk... ghk....
She gathered saliva to serve as lube, replacing Sujeong's spit with her own.
"Mmm... that's more like it. Watch carefully and learn, sis. This is how you give a blowjob."
"A blowjob..."
Sujeong stared at Mom in a daze.
Sweaty, wearing nothing but underwear, sucking her own son's cock—Mom looked both beautiful and like pure sex.
How can Mom do this...? Isn't she our real mother?
Even as the thought ran through her, she found herself marveling at how deep the cock was going.
I can't do it like that...
Some unnameable competitive streak flared in Sujeong.
Mom kept sucking earnestly for a full five minutes.
In the silence, the way she obediently worked my cock without a single word of protest was almost impressive.
She'd pull off with spit still coating me, suck it back down with a wet sound, swallow, and lay down a fresh layer of saliva, all with practiced skill.
"Well? Mom's pretty good, right?"
"Y-yeah... I mean... yes..."
Watching a woman perform a sexual act got her aroused.
As she watched Mom suck my cock, Sujeong felt her own pussy growing wet.
The front of her blue panties had darkened to a faint indigo—visible even from where I stood.
"Mm, I think I'm about to cum. Give it a little more, Mom."
Mom tensed her throat and took me even deeper.
Ghk.... ghk... ghk.... squelch.... ghk....
The veins stood out on her neck.
That's... she's serious about this...
Sujeong could tell Mom was sucking my cock with genuine devotion.
Feeling the piston of Mom's mouth, I looked at her chest and gave the order.
"Han Mijeong...! Show me your tits."
Even with her name called in front of her daughter, she didn't so much as flinch. Still sucking, she pulled the cups of her bra down and bared herself.
"...Mo.... Mom..."
Sujeong looked ready to cry.
Mom's total submission to me seemed to frighten her.
In Sujeong's mind, the illusion of who her mother was was shattering piece by piece.
The mother who had stood strong against the loan sharks. The mother who had worked the phones for us, scraping together money. The mother who made breakfast every morning and told us not to worry. The mother who had spoken so calmly about forgetting their dead father. The reliable mother who had left for Seoul swearing she would find a way to get the money.
Seeing that same mother in complete submission before her son filled Sujeong with dread.
Every part of Mom except her pussy was fully exposed.
I admired her breasts and came cleanly, straight into her mouth.
Byuut....!! Byurrut....!.. byulk.... byurrulk.... byurrr......
"Don't swallow. Show it to Sujeong."
Like a machine, Mom obeyed her son's words exactly.
She turned her body to face Sujeong.
Her breasts, slicker with sweat than before, glittered above the peeled-down bra.
Mom looked Sujeong in the eye, then opened her mouth and displayed the cum pooling inside.
Zzeok—
From the day she had given me everything, Mom no longer had any pride left where her daughter was concerned.
"Ah.... Mom..."
Sujeong trembled, caught between arousal and terror at the sight of the semen in her mother's mouth.
"Now swallow."
Gulp— gulp—
Mom swallowed the cum and opened her mouth again to show me it was gone.
"You're keeping your promise from back then."
I stroked Mom's head.
Sujeong was still reeling from the shock.
On Mom's face there was nothing left but the look of a female in heat.
She put her bra back on and waited for my next command.
"Looks like Sujeong's in shock. Good work, Mom. Sorry for calling you away from your yoga~"
"Not at all. Then I'll go back to my yoga~"
Mom stood as if nothing had happened and left. She glanced at Sujeong once, but there was no worry in her eyes—only the superior look of a favored bitch surveying a female who had fallen behind.
As if flaunting that she was the one more loved.
Sujeong's eyes were unfocused.
At first it had been awe.
A jealous sense that Mom was monopolizing the pillar that was her son, mixed with the thought that if she just tried hard enough she could suck him the way Mom did.
But little by little the excitement had turned to fear.
Mom was no longer the mother she had known.
"This is insane... this house is insane..."
Sujeong muttered to herself, went to her room, and shut the door.
Slam!
Maybe I pushed too hard.
Figuring she'd come out eventually, I decided to leave her alone.
Mom was diligently doing her yoga.
When our eyes met, she smiled sweetly and kept going.
"Mom, you're incredibly flexible~"
"Hoho~ Thank you, Master. But Sujeong... do you think she'll be alright?"
She asked, stretching her hips back in a long line.
"She'll have to adjust. You were amazing, by the way."
"I did something terrible to you, Master... Even now... I want to make it up to you."
"Mom, thank you."
"No... I'm... grateful too."
Mother and son. Slave and master. Casual speech and formal speech. Even this situation itself was turning her on.
And then something unexpected happened.
Around dinnertime, Sujeong left the house.
"Guess the shock hit her pretty hard."
"Seems so..."
Mom was worried, but she showed no sign of wanting to go look for her.
"She'll come back on her own, won't she?"
Sua said to Mom.
"Well, she'll figure it out and come home, right?"
Mom set down her spoon without much concern, and dinner for the three of us began.
Sua barely said a word, and Mom seemed to be in a good mood, but the meal ended in near silence.
I finished eating and lounged in front of the TV, but a growing unease lingered in a corner of my mind.
