Chapter 173
"Aunt Seon-ju! Do you have a moment?"
Just as Aunt Seon-ju’s entire face was becoming evenly coated with Si-woo’s pre-cum, Si-woo looked down at her and spoke in a grave voice.
—Using the title 'Aunt,' just as he did when he was with his younger cousins.—
"Uh... huh? Wha... what is it?"
Aunt Seon-ju stammered her reply, looking bashful at the familiar title and Si-woo’s usual way of speaking.
It seemed that now, even when they were both naked and aroused, it felt more awkward for her when Si-woo treated her like his aunt.
"There’s something I want to ask you... Can you give me an honest answer?"
Si-woo continued to speak, still letting the transparent fluid drip onto her face.
He intended to ask her about the contents of the Slave Contracts he had discovered today.
—Not as master and slave, but as aunt and nephew.—
"What... what do you want to ask~?"
Aunt Seon-ju answered her nephew, her eyes closed and her head tilted back as she took the pre-cum head-on.
Though he had brought it up seriously, Si-woo felt a sudden wave of uncertainty about where to even begin.
He mindlessly wrapped one hand around the base of his penis and shook it up and down, as if flicking off the mucus gathered at the tip of the glans.
Tap! Tap! Tap!
As his penis rose and fell, it drummed against Aunt Seon-ju’s closed eyes and the surrounding area.
"Hng!"
Aunt Seon-ju let out a short moan, sounding startled and tense.
At the sensation of the flesh suddenly striking her and pulling away, she held her breath and ducked her head.
"Haah..."
Soon, realizing that Si-woo’s heavy length of flesh was striking her face, she relaxed her hunched body and exhaled.
"You signed one too, didn't you, Aunt Seon-ju?"
Si-woo asked, omitting the subject of the sentence.
"Signed what~?"
Aunt Seon-ju curled the corners of her mouth slightly, asking back as if she already knew exactly what he wanted to know.
"Don't play dumb! I'm talking about the Slave Contract!"
For the first time, Si-woo mentioned the Slave Contract directly.
"......"
Whether she was hesitating or just trying to tease him, Aunt Seon-ju kept her mouth shut for a moment.
Si-woo swung his cock shaft sideways like a baseball bat.
Thwack! Thwack! Slap!!
As if to hurry her along, his shaft struck her chin and cheeks alternately as she held her head up.
"Hah-eut...! I... I signed one! A long time ago!"
Aunt Seon-ju answered, her body flinching.
Her expression crumpled slightly, as if the swinging blows of his shaft actually caused her some pain.
"Was it by force?!"
Si-woo asked, shaking his shaft up and down again to lightly drum against her face.
Aunt Seon-ju seemed to think for a moment, then shook her head from side to side in time with the rhythm of the swaying penis, as if denying his words.
He didn't know what thoughts had made her hesitate, but it seemed she hadn't signed the Slave Contract against her will.
"Mom knows too, right? That Su-a is Dad's daughter!"
To keep the conversation moving, Si-woo asked for confirmation on a fact he had already vaguely surmised.
Aunt Seon-ju smiled and nodded as if affirming his words.
"Does Su-a know? That her uncle is actually her father?"
Si-woo began to grill her on the facts regarding his younger cousins.
"She knows~ I've told her who her father was since she was little... including the part about keeping it a secret from everyone else!"
Aunt Seon-ju answered as if such a thing were only natural.
Si-woo had suspected for a while that Su-a knew the secrets of her birth.
Even so, hearing it directly from Aunt Seon-ju made the vague imaginings in his head feel like a sharp, physical sting to his chest.
"Dad and Su-a! Did they have sex? Did she sign a Slave Contract too?"
Si-woo used blunt language, trying to confirm the specific details.
"No~ Su-a hasn't done that with her father! And she hasn't signed a Slave Contract yet, either!"
The answer coming from Aunt Seon-ju’s mouth was different from what Si-woo had expected.
"The video you sent me from the pension last year!? What was that then? Wasn't Su-a offered to Dad as a gift for his birthday?"
Based on the materials she had sent him, Si-woo brought up his theory about what happened at the pension last year, questioning her with doubt.
"That was the plan~ but it didn't happen! Your dad said he’d wait until Su-a started her period."
Aunt Seon-ju answered his questions with her eyes squeezed shut.
Her hands, gathered demurely between her knees, did not leave the floor.
Was Dad waiting for Su-a and Se-young to have fully developed female bodies?
Upon hearing Aunt Seon-ju’s explanation, Si-woo felt a strange sense of relief.
The tension that had been knotted in the back of his neck seemed to melt away.
"Then what about the photos of Su-a posing with a sign around her neck? She was being trained by you, wasn't she?"
Si-woo pressed her, determined not to leave any lingering doubts.
"She didn't sign a Slave Contract! Su-a has been doing things like that since she was even younger."
Aunt Seon-ju explained the situation regarding Su-a as if confessing the truth under his interrogation.
"Did you do it to Se-young too?"
With a trembling heart, Si-woo asked about the matter that concerned him most.
—Whether Aunt Seon-ju had performed that kind of training play on Se-young, just as she had with Su-a...—
"Did I do what?"
This time, Aunt Seon-ju asked back as if she didn't understand what he meant.
"I mean what you did to Su-a! The strange things Se-young has been whispering to me lately, and all her weird behavior—didn't you make her do all that?!"
Si-woo asked about Se-young’s strange actions and attitude toward him lately.
It was as if he were trying to purge every last bit of murky sediment that had settled in his heart.
Aunt Seon-ju faltered at his question, her expression turning surprised.
—Though her eyes remained closed.—
"...You weren't asking because you already knew~?"
Aunt Seon-ju’s reply followed with a playful laugh.
"Wha... what do you mean?"
Si-woo asked, flustered by the sudden change in her expression and tone.
"I guess Si-woo doesn't know yet~? I thought you checked everything today! Well, I suppose you'll find out soon enough?"
Aunt Seon-ju spoke as if there was something Si-woo was supposed to have confirmed.
Shame began to boil inside him again.
"Wha... what... what don't I know? I'm asking if you're the one who made Se-young act so strange lately! Just answer the question!"
Si-woo condensed his question and demanded an answer.
His tone and inflection had turned somewhat coercive.
"No~ I didn't do anything like that to Se-young. I'm not exactly in a position to order her around like that~"
Aunt Seon-ju spoke firmly, denying his suspicions.
"Anyway, she really is her mother's daughter... our Se-young likes Si-woo way too much~!"
Aunt Seon-ju continued with a cryptic monologue.
She took her hands off the floor and placed them on Si-woo’s bare thighs.
"Wha... what are you talking about?"
Si-woo was flustered by her sudden touch.
"I wonder~? Hehe."
Aunt Seon-ju stroked her hands up and down his thighs, begging him to do something to her quickly.
* * *
Fortunately, if what Aunt Seon-ju said was true, it seemed Su-a and Se-young had not yet had sexual relations with another man.
And unlike Su-a, it appeared Se-young had not received any sexual discipline or abuse from Aunt Seon-ju.
But if that were the case, how could Se-young’s recent strange behavior and attitude be explained?
Aunt Seon-ju’s subsequent words lingered in Si-woo’s mind, leaving him feeling confused.
Was there something else I was supposed to check?
I still have so many things I want to ask...
What did she mean when she said she wasn't in a position to order Se-young around?
Si-woo looked down with contempt at Aunt Seon-ju’s face, as she sat there with her eyes closed and a sly smile, her face still wet.
He realized that asking questions like this anymore would be useless.
Si-woo grabbed the hair on the back of Aunt Seon-ju’s head with one hand.
Then, he pulled her tilted head forward, forcing her to look straight.
"Open your mouth! And from now on, don't use formal speech until I tell you to! Don't call me Master, either!! Understand?"
Si-woo commanded her in a stern, rebuking tone while gripping her hair.
Instead of answering, Aunt Seon-ju opened her mouth as ordered.
—Shove!
As soon as her mouth opened, Si-woo adjusted the position of the tip of his penis with one hand and thrust it deep into her wet throat.
Aunt Seon-ju’s moist tongue, the slippery flesh of her mouth, and the warm membranes of her throat wrapped around Si-woo’s penis.
"Guh-urk! Hng!"
The sounds of Aunt Seon-ju’s gagging and moaning echoed through Si-woo’s room, as if finally set free.
