Chapter 004: Forcibly Piecing It Together – This Is a Master-Slave Reversal World. Things Are About to Get Juicy.
"Nngh...! Damn! If you're gonna ask more questions, this time grab my nipples too and twist them...! And you! I told you not to use formal speech with me...!"
"...Oh right. Yeah."
Jin Yuseong tried his best to obey her words faithfully, but it wasn't easy. He was flustered by her comment about "planting seeds." Plus, how could he casually talk down to such a stunningly beautiful stranger? He was still a virgin. Even if he couldn't switch to casual speech right away, his hands were already groping her in real time—but hands were hands, and words were words, he justified to himself internally.
He pinched and kneaded her soft flesh. Squish, squish! Pinch, press!
"Nngh...! Haa, haa. Normally, we call summoned familiars 'slaves,' but familiars aren't...! Haa. It just varies by contract level depending on how well commands are accepted... Eek! They're all the same—witches grab hold of our lives, and we're obligated to play with our master's body for the rest of our days, so if they're summoned for service anyway, calling them slaves instead of familiars or summons fits, right? Hng...! Got it up to here? Haah...!"
"Ohhh, I see~"
He hadn't understood a single word. Jin Yuseong was distracted by her moans and her soft body, and the master-slave dynamic was so far from his common sense that he just pretended to get it.
"You must have it rough... Hngit! ...Hah...! Haa...! R-Rough, huh...? Seeing how your common sense is so lacking... Haaah!!"
Squish— Squelch—! Midway through her words, her underwear was utterly soaked. Staring intently at the erotic sight, Jin Yuseong didn't stop kneading her breasts. No matter how much he groped them, he couldn't get enough of that softness.
Fuck, I have no idea what she's saying, but damn, it's soft.
As he massaged the self-proclaimed master's body—the silver-haired beauty—Jin Yuseong managed to cram the explanation into his head, even if the very existence of such common sense felt emotionally incomprehensible.
"Haa... Haa...! Even though I caught you off guard and deep-kissed you, sealing the Absolute Obedience Familiar Contract and making you my slave... Hngit! I'll... I'll cherish you...! Eek... Just obey my commands well and play with my body for the rest of your life...?"
Play with her body...? Flustered by the lewd demand, Jin Yuseong asked just in case.
"For life... uh, does that mean I can't go home anymore?"
"No way!!"
A firm answer.
"From now on, you're stuck by my side forever, training my body, developing it, impregnating it! You've got so much to do? You're already my slave, so don't even think about leaving me!"
Train the master, develop her, impregnate her...? Haa, my head's spinning, fuck...
He'd only asked just in case, and since he was a shut-in anyway, he didn't mind not going back. Still, hearing such a concrete vision of his future left him dumbfounded.
"......If we're doing all that, then what about marriage for you, Master?"
"...? Marriage? What's that?"
She didn't even understand the word itself. She'd thrown the question right back, clueless about its meaning.
No marriage here at all. What kind of world is this?
With a question mark practically floating over his head, he explained the concept of marriage to his adorable, head-tilting master. Sylvia's reaction upon hearing it all was a face like she'd heard something bizarre.
"Ha! We don't do that hassle of a weird ritual. Your world sounds so strange? Well, there is one vaguely similar thing that comes to mind."
Jin Yuseong thought this world was the strange one but held his tongue.
"Similar thing?"
"Sometimes, if a slave plays with their master's body really diligently and makes her feel super good, she might give him allowance as a special treat? But it's not like he can spend that allowance freely. There are things he absolutely can't pay for, so it's restricted where he can use it."
Allowance... Another absurd term popped up, but he couldn't bring himself to point it out again.
"What kind of restrictions?"
"My mouth hurts. If you wanna hear more... kiss your master!"
"Uh... Got it."
Smack! Smack! Jin Yuseong had gotten a bit excited listening and pecked her quickly like a sparrow, eager to hear the rest. Truth be told, since it wasn't a "command" but something he initiated himself, he'd hesitated a little. Surprisingly, Sylvia seemed satisfied and moved on without complaint. Grinning, she touched her lips and continued.
"First off, never spend the allowance your master gives you on any other bitch! That's the most important rule—remember it? Usually, slaves spend it on clothes or food for themselves, leisure stuff like that... But remember how you mentioned something like marriage?"
"Yeah."
"That's when a slave wants to express special feelings for the master who gave the allowance. As someone obligated to play with her body for life, it's for buying personal tools to handle her beyond what she provides for training and development. Or buying dedicated accessories to adorn her body and offer them up. It's rare among slaves."
"Whoa...... My head's spinning......"
Training tools, development tools, dedicated accessories—what the hell? The man clung to his sanity and decided not to stop caressing his master.
"Heh, you're from a world with different common sense, so it might be hard to grasp. Hng! No matter how curious you are, prioritize playing with your master over listening...! Hngit...! Yeah... like that... Ah...! The explanation's getting long, so keep kneading my breasts... and grope my ass too... Ahit!"
Jin Yuseong had paused his thumb circling her nipple in a daze. This was his greedy master's order to add another hand to the caressing. He obeyed as instructed. As she trembled under the attention, she spoke.
"Hiiiit...! Haa... Haaa... Where was I...?"
"You were almost done with the marriage-like thing."
"Right! That thing similar to marriage is... Huu... the [Slave-Master Oath Ceremony]."
".........What's that? The name alone sounds ominous...."
"Haaang... Even to you, it sounds like... Jiit!"
Shiver!Squish— Squish—
She's cumming way too easily... Is this normal for women? Isekai human trait? Or is she just super sensitive...?
Having climaxed from her slave's touch, the shuddering master panted and continued her explanation.
"Haa... Haa... The [Slave-Master Oath Ceremony] is a super special event not every master gets. It can't be accepted through a 'command'—it has to be purely the slave's own initiative."
What kind of free slave is that? As he gaped in disbelief, Sylvia kept going.
"If a slave chooses to buy an [Absolute Obedience Slave's Clit Ring] with his allowance and decides to put it on his master's clitoris, then the master becomes the slave's slave in return. She serves his body just as he's served hers all this time. For life, by his side."
"???"
He furrowed his brow, parsing the meaning.
What? The master becomes the slave's slave. But she stays the master too? So she's a slave-master slave?
"Of course, masters already get to grope and enjoy their slaves' bodies freely, so nothing really changes. It's just a formal oath to show sincerity. But even if it's formal, the [Absolute Obedience Slave's Clit Ring] carries a powerful curse that grants the wearer absolute command over the other."
"Ooooh................"
Long explanation short: using the master's allowance to enslave her was a rare, special occasion. From his perspective, wishing for nipple piercings or clit piercings was bizarre, but if it was the custom here, what could he say?
Fuck... so basically... the slave isn't really a slave and has it super easy? Yeah, something like that.
Jin Yuseong tried to make sense of it, then refocused on his slowed caresses. She whimpered at his sticky, groping hands.
"Haat... Hng... Hng... Feels good...♡"
"You keep saying 'absolute obedience'—is it the same as what I know?"
"Nngh, hng... Really?"
"Is the absolute obedience from my contract the same as that accessory curse? Can you explain?"
"Hiiiing... Hng... Ah... Haat...! More questions? Kiss me once... and don't stop playing with my body...♡"
"Yeah, got it...."
Her perverted demands in that sultry voice made it impossible to calm his arousal.
Fuck, my dick's killing me.
It felt ready to burst. Living as a slave here's no big deal, but I'm gonna cum soon. He was desperate. With such a perfect setup, the virgin was determined to cum inside, not out. Eyes bloodshot, he held back. But his doubts lingered unresolved, so he threw out one last question.
Even if it meant more obligatory groping of her gorgeous, arousing body with every query. Even with his cock throbbing painfully erect. He had to know if all this "absolute obedience" was the same.
Ugh, fuck it—should I just ditch the questions and fuck her? No, I can hold out...!
Smack... Smooch... Slurp... Suck... Smack...♡
After sucking on each other's tongues like melting candy, Master Sylvia answered about absolute obedience.
"Haa... Haa... Absolute... absolute obedience is just that—absolute obedience! Both are magic signals straight to the heart saying 'obey'! Hngt! You have to obey every word!!"
"...No fucking way!"
"Haahut!? That word just now... might feel good...♡"
"...Fuck? This feels good?"
"Nngiiit...! Haa... Haa... When you pinch and twist my nipples hard and that unfamiliar sound hits my ears, it feels so good...♡"
"Whoa... okay then..."
Jin Yuseong felt deflated. Absolute obedience was exactly that—no hidden meaning. This master—this woman—was a total masochistic bitch, and he, her slave, was the stud who'd spend his life playing with her and sticking by her side. The absurdity hit him.
This... is slavery?
Huuu...... A sigh mixing relief, joy, deflation, and surreal disbelief. One worry nagged him.
Haa... getting off on insults? Better to make her cum on my dick. I'm no masochist; I suck at trash talk.
He'd already accepted his future of pounding his master Sylvia senseless while groping her freely.
She's super sensitive. What was her name again? Sylvia something—make her cum once, then sneakily ask and memorize it.
Jin Yuseong kneaded her child-bearing hips, slim waist, and massive baby-head-sized tits. He'd embraced his duty to train, develop, and breed his master's body as he pleased.
"Hng...! Y-Yuseong... To the b-bed..."
"Got it, Master Sylvia. And it's Yuseong, not Yusei—call me that."
"Uuuung...! Yusei...! Yusei...!"
"Sigh."
Couldn't she pronounce Yuseong? But how did their languages even work? He pushed the thought aside. Following his master's lewd request, he climbed onto the bed. He'd decided what to call this isekai he'd been summoned to.
A world where slaves play with their master's body daily. One where you could even turn the master into your slave. In short, a realm where the master becomes the slave's convenient sex toy.
Master-slave reversal world. Yeah, that'd do.
