Ah, It's Common Sense for a Slave to Knead His Master's Body During Bath Service
'Ha, sex again.' The blanket lifted slightly, revealing the pale curve of her neckline and the deep cleavage beneath. Lowering his gaze further, the sunlight piercing through highlighted the pink areolas hidden under the covers, asserting their presence even in the shadows.
Jin Yuseong recalled the moment from the night before when he'd last cum inside her—the lewd appearance of his master, Sylvia Armani Rune Lumer, sprawled cat-like on his body, impaled on his cock, her breasts squished flat as she gasped for breath.
[Haang!Haaang! Master! You know my pussy's all grown up now, right? It took your cock so deep and held all your cum! Now cancel that flesh slave oath? You can be my slave again, right, Yusei? Aaang!]
Her hips swaying seductively as she begged. He'd roughly replied that he got it, then deep-kissed her while creampieing her. Hands on the slender waist of his master, Sylvia Armani Rune Lumer, teasing her perfect areolas and nipples during the deep kiss—! Tongues flicking wildly as cum spurt! spurt!gurgle gurgle flooded into her womb!!
That was where Jin Yuseong's flashback ended. He became aware of his dick, now rock-hard. Even after last night's frenzy, it showed no signs of fatigue, throbbing eagerly.
"Sylvia, Master. It's morning. Time to get up?"
"...."
Jin Yuseong tried waking his master, erection and all. No response from Sylvia. He pulled back the blanket.
"Uuuung~!"
'Where's this tantrum coming from? So cute.'
No longer a virgin, Jin Yuseong decided to try a sweet hero waking his heroine this time. He leaned in gently, pecked her sleeping lips—smack—and as her eyelids fluttered, locked eyes and slipped his tongue inside...
Sylvia's lips parted, her tongue reaching out to meet his. 'Feels too good.'
Jin Yuseong stroked her silky silver hair like fine silk while sharing a morning kiss. Her lips and locks were incredibly soft.
"Smack. Mmm, slurp, smooch, smack♡"
His master Sylvia fed like a baby bird on her slave's tongue. Ah, this was true slave service. Reversed world—adaptation complete. Three minutes in, maybe five. To an outsider, they'd look disgustingly lovey-dovey, smooching away. The sleeping girl between them finally opened her eyes.
Jin Yuseong greeted her awakening with a loving voice. "Awake now?"
"Yeah. Hehe♡ Slave, not bad, huh?"
He gazed at her lips. 'What exactly is "not bad" about this master?'
As if reading his mind, Sylvia replied. "Yusei got summoned from some weird world with fucked-up common sense, yet you wake your sleeping master with a kiss that feels this good? Amazing. You've got real slave talent!"
'Oh, that's what she meant. Puhehe.'
Gazing fondly at her, Jin Yuseong burst out laughing at the praise.
"What's so funny, hehe! Don't laugh like that!"
His laughter set her off too. The slave and master lay naked on the bed, stroking each other's faces, giggling for a few more minutes before finally rising.
"My slave, you don't know how to attend a bath, right?"
"Yeah, never done it."
"No clue at all?"
"Bath service? Only thing that comes to mind is washing her instead. What's more?"
Reminded of her forced enslavement via his hand, she explained considerately. "Before my coming-of-age, I'd magically clean myself in a snap—annoying as hell. But now with a slave? No way. From today, you'll scrub me from head to toe, nice and thorough with those hands."
"Ooo...."
Interlocking fingers on the way to the bathroom, Sylvia continued her lecture on master bath service. "Listen up. When washing your master, focus on sensitive spots—rub 'em hard, stimulate like crazy. Some feel it too much, but not me, so skip that. Even if your master's a sobbing mess, keep going! Bath service is serious—don't stop no matter how she looks."
"Ooo...."
"Pussy and nipples get played with like toys a lot, so clean 'em meticulously. Peel back the clit hood, wipe off dried slave cum and her juices. Finger the pussy hole deep inside too. Hm! What was I saying while explaining—?"
"Ah."
Smack♡ She tiptoed up, clinging for a kiss. Jin Yuseong quietly reviewed her words while kissing. 'Kuku, what kinda bath service is that?'
Steeling his dizzy mind, he memorized it. "...So, tease her senseless while washing?"
"Huh? Heard it all? Then show me. I'll watch how good my slave is."
"Got it, Master."
"Fufufu. Banmal coming naturally now?"
She smiled, pleased with his attitude. Such a pretty smile. Matching her nudity, Jin Yuseong shed his robe. Taking the lead from the girl who'd guided him hand-in-hand, he got proactive.
He handled the bathroom tools he'd used once before with familiarity, washing her meticulously. Never shampooed a girl's hair, but he was diligent.
"Mmm... You'll get better. We'll do this together from now on. I've only magi-cleaned too, so can't judge. Ah, gentler... Uuung... Yeah, like delicate fabric—careful..."
Her kind advice with every stroke made him love bath service instantly. Shooo—rinsing foam from her hair, long strands clung like seaweed. He peeled one from her cheek. Even wet and limp, she was beautiful. Addicted to her loveliness in every form, Jin Yuseong lost his heart more. He truly enjoyed deflowering his master and their naked intimacy.
Shwaaa—
"...No big tips needed—you're good. Staring like you're licking her body? Perfect too."
"This is doing it right?"
Nod nod. His cute master nodded, insisting on her slave's greatness.
"Heard stories only, but no slave this aggressive with his master! Worth stealing Mazo's name for the ancient chant."
"Huh? Stealing?"
"Hehe. Borrowed pioneer witch Mazo Brunhilde's name for the summon."
"You can just do that... no issues?"
"Fine. She's a maso."
'What kinda logic...?' Giving up on the arcane magic world, he resumed service.
"Haaaang. Haang. Go-good... You're good... No orders, yet you slather on soapy lotion all slippery..."
Rub rub.
"Hngt. Haht... Aang!"
His fully erect cock twitched visibly; Sylvia reached out.
"Hng."
Her slender fingers coiled around Jin Yuseong's dick.
"Why so surprised~? Right, otherworlder... Great! Lesson time. Save up all the kisses you owe while I explain—I'll collect later."
"Ugh... Uh."
Fiddle fiddle... Sylvia gripped his cock, stroking the skin up and down.
"Master's body all managed by slave hands—hers get bored. So if slave gets excited, she can touch like this. Yours stands way harder than other witches' slaves...♡"
"Ngh. Hurt a bit just now."
"Ah. Sorry! Careful!"
Midway, she'd scratched the glans with a nail—wrong move, she pulled back. Jin Yuseong patiently taught her how to handle his dick. His slave-master picked up handjobbing fast.
"Ugh, quick learner, huh Master?"
"Really? Ehehe♡ You teach well, Yusei."
Locking eyes, the silver-haired beauty master enjoyed stroking her slave cock more. Pat pat pat!
In thanks, Jin Yuseong washed her even more devotedly, obsessively. Fitting for 'bath service'—mostly erogenous teasing over cleaning.
Fiddle fiddle.
"Heet! Armpits. Tickles, aheet!"
'Kuku, train her armpits too. Got a lewd master straight from Adana fantasies, and she wants training, dev, pregnancy—gotta deliver.'
He tickled her pits while fingering her pussy. The bathroom grew lewder.
"Haang, just ticklish but... Feels good..."
Hearing her sweet, slutty voice up close, Jin Yuseong grew familiar with her body. Teasing to make her think pussy pleasure came from pits, and her slutty flesh actually buying it. Shaking off hesitation as isekai common sense—developing master's body.
Rub rub.
"Ah... Aang! Aaang...!"
Her body trembled pitifully under his thorough scrubbing—then she squirted.
Squirt! Squirt!
After his sticky fingering, pussy juice and squirt sprayed his palm. Shifting, Jin Yuseong kissed her puckered lips close-up.
"Mng, smack, slurp slurp, smooch, haa♡"
Twitching in climax, she still responded eagerly to his deep kiss. Commendable, he thought. Slipping a hand between her armpits, he stroked her back in praise.
"Heeung, haang...♡"
Mingling tongues to her cute moans, he etched her charm deeper.
Puha— Nooo—don't let go— like a sad disaster flick, her silken tongue snapped from her tiny mouth, parting from his lips. Sad ending. Their connecting thread broke fast.
"Haa... Haaa..."
Sylvia looked wistful. Jin Yuseong stroked her hair, banishing the sadness in her eyes.
Their lewd romance scene. In the pink haze, he spoke to his master. "Now, deep clean that pussy."
She flinched at the vulgarity—not disgust.
"Uht, kinda scary. Uung. Expected it, but why...?"
Perplexed by her shy reaction, she spread her legs wide on the tile, lying back. Incredibly arousing pose.
"Haa... Haa... Lie reverse so I can keep holding slave cock. Lower body by my head—close enough for you to reach my pussy."
"Whoa... Virgin yesterday, and you think of that right away? Born slut or impossible."
"Uuuung~ Just didn't wanna let go of slave cock?"
He lay as instructed, head on her soft thigh, spreading her pussy with his hand.
"Haaaang...♡"
Pat pat pat! Sylvia slowly pumped his cock, peering at her spread pussy.
Awkward pose, neck craned—but eyes glued to his washing. Watching her slave play with her pussy fueled her excitement.
"Clit hood. Peeling?"
"Uh, yeah..."
Voice laced with shame, fear, anticipation. To reassure, his left fingers stroked her folds—then right thumb pulled up the hood.
"Heeeet!!"
Body melting from the caress, she yelped in shock. Pointy pointy. First time exposed—clit bare.
"O... So red."
"Hauuu...."
Staring intently, he met her eyes. Face flushed, she froze, mesmerized by her slave toying with her pussy and the peeled clit.
"Haa... Haa..."
Her paused handjob resuming slowly signaled him. He gingerly pinched the glossy clit between fingers, rubbing softly.
"Hik, heungit!"
More chill than pleasure—she shrieked. Biting lips, hips quivering; he lightened his grip.
"Huu, hau, clit... Weakest spot... Peeling makes it weaker... Handle carefully...?"
"Y-yeah... Got it."
Nodding to her teary plea, he held the clit gently, no more rubbing—focusing inside first.
"Haaang...♡"
Pounded hard last night, yet no burn or swelling. 'Mana magic fix, probably?' Brushing off the thought, he fingered the barely-pink slave-toy pussy.
"Haang! Ang! Slave fingers in pussy♡!"
"Master... Don't tease. Slow the handjob."
"Ah. Uung, sorry for arousing you. Distracting?♡"
"Nah. Kuku."
Close to cumming, but he wanted to sustain the heat for service. Post-nut clarity might kill the lewd vibe. Gritting, hold back—scoop out last night's creampie.
'Pity, hate removing it. But bath time—gotta clean.'
Loath to erase his mark, but duty called. 'Tch. Can always cum more later.'
Thus, he scraped and rubbed her depths.
"Ah, ah! Huat! Ahng! Love bath service♡ Wasted life till now♡ No more magi-clean ever♡"
"Really now. Then dig harder."
Her moans as appetizer, he smirked, fingering boldly. Other hand's clit throbbed pointier, begging; mid-thrust, he teased her exposure-fetish nub lightly.
"Ng—Giiiit♡!!"
Pushoo! Psht!! Pussy juice gushed pussy pussy.
'Playing with girl's body is fkn fun.'
For a full hour, Jin Yuseong made master Sylvia cum eight times; her handjobs brought him off twice. She licked up every drop of his external cumshots—such a waste otherwise—
