Enjoying Daddy Play with Sinia
Actually, on the day Sinia returned, she asked me for a favor.
She wanted to know if she could call me “Daddy” again when the two of us were alone.
When I pointed out that I thought that was just part of her undercover disguise, Sinia stayed stubbornly silent.
Why did she want to call me Daddy so badly?
I couldn’t understand it.
It wasn’t a difficult request, so I agreed, but the truth was I almost never got to hear the word “Daddy.”
My schedule was ridiculously tight, and finding time for just the two of us was nearly impossible.
The reason Sinia had been drifting away from the other monmusu lately…
I would only find out by hearing it from her own mouth.
That’s why I secretly called her to my room during the sleep hours that were supposed to be my rest time.
“Daddy… why did you call me??”
The moment my door closed, Sinia called me Daddy and threw herself into my chest.
“Whoa! You can’t just jump on me like that~!”
I couldn’t withstand Sinia’s hug and toppled backward onto the bed. She naturally climbed on top of me, rubbed her nose against mine, and spoke.
“Daddy… I love being alone with you like this… Sinia is so happy…”
“Yeah… if you’re happy, then I’m happy too.”
No matter what, playing the role of “Daddy” for a twenty-year-old was incredibly exhausting.
Back when I genuinely thought of her as my real daughter, I was clumsy but sincere. Now that it was pure roleplay, the words didn’t come out as naturally.
I laid Sinia, who was sprawled on top of me, down on the bed.
Then I sat on the edge.
I wanted to talk first.
“Sinia. Ever since the runaway incident… have you been awkward with the other monmusu?”
“Huh? Does it look that way?”

Sinia answered in a playful tone, then started stroking my back with both feet, teasing me.
But it wasn’t going to work.
I continued with my questions.
“It’s not really a big problem right now. But we all live together, and I was worried it might be hard on you if you kept drifting apart. If everything’s fine, then I was just worrying for nothing…”
“…”
Sinia stayed silent, only rubbing my back with her feet.
But the way the pattern became monotonous made it obvious she was thinking about the question I’d thrown at her.
“It’s just… I… I deceived my family…”
“Hm?”
“I feel bad about it. Even if I was under a spell… I lied from the very first day I came to the ranch…”
If someone had told me last year that a monmusu could feel shame, I wouldn’t have believed them.
But right now, Sinia was confessing a very human kind of emotional struggle.
“Not all lies are the same. You don’t have to carry that whole burden by yourself.”
“Still… I feel like my very existence is a lie… Um, can we talk about something else? It’s too heavy, Daddy!”
Sinia tried hard to change the subject.
But one thing in her words had caught my attention.
“Sinia. You’re not a liar. You were honest from the very beginning.”
“Me? Honest?”
I nodded and kept speaking.
“Setting me up as your dad… wasn’t that actually something you wanted? So even if you were pretending to be my daughter, the desire to call me Daddy was the same then as it is now. Right?”
“Ah… haha. I guess so.”
Maybe embarrassed, Sinia clapped her feet together and played it off with a silly act.
But I felt like I could hear the sound of her heart opening.
Of course. If anyone feels like their existence is fake, they’re bound to shrink back.
In times like these, you have to boost their self-esteem.
“The reason I allowed you to call me Daddy again… is because I could tell you truly wanted it. Honestly… it’s not easy playing dad when I’m not actually your father. But when I play the role and see how happy it makes you, Sinia… it makes me want to try harder.”
“Daddy…”
Sinia, who had been playfully rubbing my back with her feet, suddenly stopped.
I grabbed her foot and gently stroked it, over and over.
Sinia kept sniffing, as if her nose was stinging.
“I’ll keep being your daddy. So go have fun with the other monmusu too.”
“Okay… Daddy. I will.”
I didn’t know how many days it would last, but the discipline seemed successful.
The real discipline, however, was only just beginning.
How nice would it be if words alone could correct behavior?
In the end, only when it’s engraved into the body does it truly become theirs.
I slowly moved the hand that had been touching her foot upward and began stroking Sinia’s thighs.
“Ah, Daddy… when Daddy strokes me with his hand like that… it feels so good…”
“Yeah, baby. Did that feel good?”
“Yes, Daddy! Sinia feels good!”
In the blink of an eye, Sinia had turned into a baby, speaking in a lisping, childish voice.
Yeah, I had expected this when she asked if she could keep calling me Daddy.
I’d suspected Sinia might have a regression kink…
Normally she was wild and quick to pick fights with the other monmusu, so the huge gap between that and how she acted in bed had genuinely flustered me at first.
But if all these different monmusu were going to live together on my ranch, I had to be the central pillar.
One single pillar that fit perfectly into countless holes.
That was me—and my Big-Ja.
I slowly spread the legs of Sinia, who was acting spoiled and clapping her feet together.
“Ah, Daddy…”
Her cheeks flushed as she completely surrendered her body to me.
I stimulated Sinia’s clit with my fingers while repeatedly saying her name.
“Sinia, you’re a good girl, right?”
“Yes, Sinia is a good girl… a good girl who loves it when Daddy touches her pussy…”
“That’s right. Good, good. Sinia has a pretty pussy too, doesn’t she?”
“Yes. Sinia has a pretty pussy… and a good girl who makes lots of pussy juice…”
It wasn’t just that she produced a lot of juice.
Sinia especially loved having her pussy touched by hand, and when she reached the peak, she had a set reaction that came with her orgasms.
“Ah, Daddy!! I need to pee!!”
“It’s okay, Sinia. We can just change the sheets, so let it all out~”
“Okay!! Daddy!! Watch Sinia pee!!”
*Drip—! Drip—!*
*Splashsplashsplashsplashsplashsplashsplash—!!*
*Trickle—! Trickle—! Trickle—!*
Sinia’s refreshing stream of piss thoroughly soaked the bed sheets.
Even while doing so, she pressed her hand against her urethra to make the already strong stream shoot out even harder.

“Daddy! Did you see Sinia peeing?!”
“Yeah, I saw. You let it out so nicely, Sinia~”
“Hehe, Sinia got praised by Daddy!!”
After a big piss, another orgasm usually follows soon after.
Sinia looked at me with moist, longing eyes while fidgeting with her pussy.
But from here on, I had to switch to teasing strategy.
If I touched her pussy right away, it wouldn’t count as proper training.
“Sinia~ Why don’t you play by yourself today?”
“Aww, nooo~ Daddy should play with Sinia’s pussy~”
“Sinia~ What did Daddy just say?”
“…”
“Play by yourself, okay?”
“Yes, Daddy… Sinia will play alone…”
With a sullen face, Sinia slowly inserted a finger into her own entrance.
But her expression changed quickly.
At first she only used one finger to stroke inside, but then—without me even telling her—she added a second finger, pushing deeper and caressing every inch.
Her face shifted from sulky to the raw, genuine expression of someone lost in masturbation.

“Sinia… you’re really good at fingering your own pussy, huh?”
“Hngh, Daddyyy— Don’t just watch… touch Sinia’s pussy…”
“No can do, Sinia. What did Daddy say?”
“To play by myself…”
Even as she whined for me to touch her, Sinia sank deeper and deeper into fingering herself.
Her answers to my questions became spaced out, and eventually she stared at me with a face that said she was about to cum from her own fingers alone.
“Sinia, are you about to cum??”
“Yes, Daddy, Sinia’s pussy feels so weird…”
“Then shall we let Sinia feel good and cum?”
“Yes! Sinia wants to cum right now!!”
Sinia sped up her vulgar fingering, shoving her fingers into her pussy faster and faster. Before long her body arched like a bow as a powerful orgasm hit her.
And the urination play that followed was just the bonus.
“Hehe, Sinia came again…”
“There there, our Sinia did so well~ You came twice today, didn’t you?”
“Daddy… Sinia wants to cum on Daddy’s cock!!”
As she spoke, Sinia was already unbuckling my belt.
Since she had followed my instructions so well, it was time to reward her with Big-Ja.
I gently stroked Sinia’s hair as she undid my belt.
Humming a little tune, she pulled Big-Ja out of my pants.
“Whoa~ Daddy’s cock is seriously huge~”
“Yeah, Sinia~ Do you want to eat Daddy’s cock?”
“Yes!! Sinia wants to eat Daddy’s cock!!”
“Good~ Shall we suck on it nice and loud?”
Sinia opened her mouth wide and gulped Big-Ja down with a loud whomp—!.
Even then she could only fit half of it, but the warm wetness of her mouth felt incredible.
“Sinia… want to use your tongue too and eat Daddy’s cock deliciously?”
“Mmm— Okayyy… slurp—!”
Not long after Sinia’s fellatio began, I felt a powerful urge to cum.
I quickly grabbed the back of her head and started thrusting Big-Ja deep into her throat.
