"Well… I kind of figured."
"I… um… I've been doing this since last year… holding it in until I can't anymore, then letting it go. It feels… good. You better not tell anyone. I'm only telling you."
"So that's why you were so distraught being locked in here."
Kagura exhaled, the pieces falling into place.
It was akin to how some girls experienced intense pleasure, even involuntary release, during climax. For them, holding it to the brink and then letting go brought a similar thrill. The constant thigh-clenching during the wait was, for many women, an instinctive, effortless way to self-soothe.
"Swear you won't tell anyone!! Or else…" Yumiko's eyes darkened, but her expression soon softened. She pinched her chin, studying Kagura thoughtfully. "Just… don't tell anyone, okay?"
Kagura was about to agree when the system interrupted: "Greetings, Lord Kagura. A quest has been issued. Choose one of the following or skip:
A: Perform cunnilingus on Yumiko Miura.
B: Ask Yumiko Miura for the panties she's currently wearing.
C: Inform Yumiko Miura that your penis is erect."
"…I'll go with C."
After eyeing the options, Kagura deemed C the least outrageous.
Back in reality, he adopted a hesitant tone. "Alright, Miura-nee, I'll keep it secret, but…"
"What?"
Yumiko scanned him, quickly spotting the issue.
"I'm still a guy, you know. Seeing something that intense…" Kagura gestured to the conspicuous bulge straining his pants. "So…"
Simultaneously, the system chimed: "Thank you for completing the quest. Rewards: Ability [Super Hardening], and one dose of 5% Female Sensitivity Enhancement Elixir."
Feeling his consciousness pulled again, Kagura asked, "What's Super Hardening? Liver sclerosis or something?"
"It's a passive ability granting your penis exceptional hardness when fully erect. It activates only during full arousal, not during refractory periods or otherwise. Are you dissatisfied?"
"Not exactly… Can I turn it off?"
Kagura found the idea of system-enhanced erections odd—he wasn't exactly struggling in that department.
"I understand your concern. However, consider this: during extended sessions with Ai Hayasaka, your erections, while strong initially, soften slightly over time. For your and your partner's satisfaction, I recommend keeping this passive ability active."
"Hm…" Kagura nodded, seeing the logic. "Fine."
The ability activated, and his consciousness returned. He recalled just pointing out his erection to Yumiko.
"Ugh… well, yeah…" Yumiko stepped closer, grabbing his arm and leading him past the vaulting horse to the gym mat. Pointing, she said, "Sit."
Kagura sat. Yumiko plopped beside him, her right hand deftly undoing his drawstring knot, yanking his pants down. His erection sprang free with a whoosh.
Yumiko covered her flushed face with both hands, peeking through her fingers, eyes blinking rapidly.
"Miura-nee… uh, first time seeing one?"
"The real thing? Yeah, first time… I'm a virgin, hadn't even kissed before. Of course it's my first!"
"Sorry, sorry."
"Ugh, you're impossible… How'd it get this hard…"
Yumiko muttered, gingerly poking it with her right index finger.
What's with this? So hard?! Is a guy's penis… supposed to be this solid? It's human tissue, yet it's like steel… though the skin's still soft, and so warm… Oh no, if something this big went inside me, I'd die.
"Ah… Miura-nee, that feels good."
"Sh-shut up!"
"Oh…"
"No, I mean… sorry, just don't make weird noises…"
Yumiko's left hand encircled his shaft, stroking tentatively.
Her inexperience was obvious—she didn't know the right pressure or speed, just awkwardly rubbing. Kagura, half-amused, said, "Uh, Miura-nee…"
"What now? I… I've never done this before… I'm not hurting you, am I?"
"No, it's fine… I just, uh, might sound ungrateful, but why are you doing this?"
"Well… because…"
Yumiko turned away, dodging the question.
Because I see you as a cute little brother. You call me 'nee,' right? You helped clean up my mess, and if you hadn't seen me down there, you wouldn't be like this. I feel responsible. Seeing you in pain, I want to help you release and feel better.
I have to protect this fragile piano boy, Yumiko thought fiercely.
"Hiss…"
"Does it hurt?"
"No… but, Yumiko, some saliva would make it smoother…"
"Saliva? Oh… you… you called me Yumiko…"
"Yeah, Yumiko."
"Fine, I'll call you Kagura then—but only in private. Normally, it's 'Miura-san.'"
"Deal."
Yumiko leaned in, brushing aside her chest-length hair. Gathering saliva, she parted her cherry lips, letting a glistening thread drip onto the tip of Kagura's shaft.
The sight of her, flushed and gripping him while delicately drooling onto his erection, was almost too much. The moment when the saliva stretched from her lips to his tip, still connected, was electrifying.
Kagura felt like he might burst.
Her rose-scented saliva coated him, and Yumiko loosened her grip slightly, letting it spread. Uncertainly, she asked, "H-How's that?"
"Really good."
Kagura's voice was soft, his legs trembling faintly.
Encouraged, Yumiko tightened her grip, speeding up. When the saliva dried, she leaned in again, adding more. Eventually, she shifted, standing beside him, her left hand stroking his iron-hard shaft, her right slipping into his pants, gently kneading his heavy sack.
Her blush never faded, lips bitten as she worked, oblivious to the class bell. Only when Kagura's breathing grew ragged, his thighs tensing, did she ask, "It's coming?"
"Yeah… Yumiko, I…"
"W-What do I do? If it gets everywhere, it'll be a mess… ugh—"
Panicking but unwilling to stop, Yumiko saw Kagura's eyes flutter shut. In a split-second decision, she bent down, taking the tip of his "steel rod" into her mouth.
Slurp—pop, pop… slurp—
Kagura gripped the mat's edge, each thrust sending thick spurts against Yumiko's palate, flooding her mouth, dripping to her tongue and throat, filling her entirely.
The unfamiliar, briny taste overwhelmed her, triggering a gag reflex, but for Kagura's sake, she persevered, lips sealed around his tip until the last drop, swallowing hard to suppress the urge to retch.
"Uh… Yumiko, you okay?"
Yumiko, hand over her mouth, battled nausea, waving her left hand to silence him.
Then the system spoke: "Greetings, Lord Kagura. A new quest is available…"
"Skip it. Getting annoying."
Though quests were tempting, this wasn't the time.
"You've skipped. Reward: Ability [Chameleon Semen]."
"What? Like… Magical Girl Sakura?!"
"No, you misunderstand," the system clarified. "Your semen will now be odorless, with flavors varying based on the recipient's preferences."
"No smell… no musk?"
Kagura rubbed his chin. Not bad—maybe he could sneak a quick session with Ai during a break.
"Your semen will be scentless, like pure water, but its taste will adapt to the recipient's favorite or desired flavor, accepted naturally."
"Oh… sounds useful. Like, if Ai loves parfaits, it'll taste like that?"
"Precisely, without seeming odd to her."
"Got it… but what about Yumiko?"
"She has consumed your semen. Would you like a one-time adjustment?"
"Do it. She's been through enough."
Kagura sighed, appreciating Yumiko's unexpected kindness.
Despite their casual acquaintance, this ordeal had bonded them, and her willingness to help him was like that of a caring older sister.
"Adjustment complete."
Back in reality, Yumiko visibly relaxed. The semen's taste morphed into her favorite mango pudding, the musky odor vanishing. Her nausea faded, her breathing eased.
Kagura and Yumiko locked eyes. She wiped her lips with a wet wipe, then crouched by his lap, grabbing his waistband firmly. "Don't move. I'll clean you up."
"Thanks, Yumiko."
"No need…"
She muttered, gently wiping him down.
Taking him into her mouth had been a practical choice—easier to clean than a mess elsewhere. Now, with no need, she simply wiped him, carefully tucking his softened shaft back into his underwear, pulling up his pants, and tying the drawstring into a neat butterfly knot.
In that moment, Yumiko made a quiet resolution.
They were discovered halfway through the next class, fortunately without major fallout.
Kagura didn't head home with Eriri and Sora that day, opting to return alone as usual. Slipping into loose slippers, he stretched in the spacious hallway, skipping the dining room to head straight to his room.
Truthfully, Yumiko's handiwork had satisfied him, but her swallowing his release—likely to avoid a mess—had left him buzzing with excitement. The drive home had been punctuated by inconvenient erections, with Nao Hayasaka smirking at him through the rearview mirror.
He was eager to find Ai and burn off the lingering heat.
But…
"Something's off about this room."
On the third floor, Kagura pushed open his door, immediately sensing something amiss.
Nothing was stolen or moved, but unfamiliar yet familiar additions stood out. A vase of three lilies adorned his usually bare desk. A stool by his bed, typically for tossing clothes, held neatly prepared outfits—something Ai usually did post-dinner. The room's osmanthus incense (Ai's signature) was replaced by faint agarwood. And…
Ai wasn't waiting behind the door.
"Oi, Hayasaka?!"
Sensing trouble, Kagura stepped outside, confirming it was his room and not some parallel world. He re-entered, heading for Ai's maid quarters.
At the door, he found a makeshift "Do Not Disturb" sign, hand-drawn on corrugated paper. It featured… a chibi version of his mom.
What the—?!
Kagura carefully lifted the sign. The chibi Sayuri, dressed in a kimono, had a speech bubble: [Butler changing. Feel free to trigger a lucky pervert event!]
"What the hell—?!"
He flipped it over—same drawing, same text.
It was unmistakably Sayuri's handiwork. Despite being the British ambassador's wife and a duchess, she'd once led a renowned BL doujin circle, doubling as artist and writer. Though she retired after marriage, her distinct style remained recognizable. Without her influence, Eriri wouldn't be an artist.
Kagura, rare to enter Ai's room, knocked cautiously.
No response.
Question marks sprouted above his head. Warily, he turned the knob, cracking the door open.
Last time, when Sora tried sneaking a peek, Ai had been ready with a taser. But now…
"???"
On the floor lay a scattered kimono—short-sleeved, for unmarried girls, vibrant with bold red and white stripes, accented by crimson maple leaves, golden-orange dahlias, and blue yin-yang fish at the hem and cuffs. The wide belt was deep blue, the lining cloth grass-green.
This… was Sayuri's favorite style. She owned dozens of near-identical sets, swapping them daily, though she'd switch to Western gowns or long-sleeved kimonos for formal events.
Gulp…
Kagura swallowed, ready to shut the door.
Ai disliked kimonos; this was Sayuri's domain. Why was she changing here? Was she… naked?
He shook off the mental image, moving to close the door.
But it caught, then swung open with a whoosh.
Kagura flinched, bracing for an awkward sight, his cheeks heating.
"Ta-da! Kagura, you're late~~!" Sayuri cackled, left hand on the knob, right pointing at him, doubling over with laughter. "Too bad~~! Five minutes earlier, and you'd have caught me half-dressed in all my shame~!"
Kagura's temples throbbed, unsure where to begin his retort.
"…Mo—Sayuri, what's this about?"
He nearly said "Mother" but caught her glare, switching to her name, which earned a pleased smile. She sauntered over, patting his shoulders enthusiastically.
Due to her whimsical belief that being called "Mom" aged her, Sayuri insisted Kagura and Eriri use her name privately.
"So, Kagura, how's my outfit? Fitting, right?!"
Sayuri spun, and Kagura's eyes landed on her hips, straining the seams of the butler trousers—tailored for Ai, whose measurements paled beside Sayuri's.
If Eriri's hips were prime "round and perky," Sayuri's were the deluxe edition.
Today's ensemble was among the strangest Kagura had seen in seventeen years. Her usual twin-tails were coiled into a Saber-like updo. Black straight-leg trousers paired with glossy black shoes and socks. Above her pronounced curves, a crisp white shirt and black vest exuded professionalism, with a partial collar securing a black tie and frameless square glasses completing the butler aesthetic.
It was Ai's Smith A. Hasaka outfit, minus the cat ears—too youthful for Sayuri.
"Uh… should I say it's fitting or not?"
"Ugh, never tell a lady her outfit's off! Even if it's true, you have to say 'fitting'!"
"Even if it's a lie…" Kagura's lips twitched. Peering past her, he asked, "Alright, Sayuri, where's Hayasaka? Why are you dressed like this?"
"Wahhh, listen, Kagura!!" Sayuri's eyes welled up. She grabbed his collar, gazing up pitifully. "I wanted to wear a maid outfit, but Ai's clothes were too loose at the chest—she's a C, I'm barely an AA. The butler suit fits perfectly, but it's such a blow to my pride, waaah—"
She collapsed against his chest, sobbing.
"That's why you're in a butler outfit…?"
Kagura's mouth nearly slid off his face.
What kind of nonsense was this?!
"Mm…! I'm pitiful, right?"
"First, explain why you're playing maid! Where's Hayasaka? Did you fire her?!"
"Oh, come on, I'd never fire Ai!" Sayuri's tears vanished, replaced by a devilish grin. Poking his chest with a wine-red manicured finger, she purred, "Lately, I've noticed some troubling signs. I get that you're at that age with… needs, but overindulgence isn't good. So, starting today, I'm swapping roles with Ai to be your personal attendant."
"Uh… what? I don't follow—"
Kagura's cold sweat poured, his face twisting away from her gaze.
Not long ago, Sayuri had announced his betrothal to Mahiro Shiina, which Kagura used as an excuse to sleep with Ai. They thought they'd been discreet, but the household's gossip queen had clearly caught on, and now she was here to settle the score.
"The maid outfit didn't fit, so I went with the butler look. Such a shame you can't sneak a peek under a skirt~ So unfortunate~"
Sayuri giggled, patting his shoulder.
"I'm not peeking at your skirt, Sayuri…"
Despite the name, she was his mother, and Kagura was at a loss.
"Hm… it'll be about a month, maybe longer, depending. You want more time with me, right?"
Sayuri ignored him, counting on her fingers.
"…Yeah, thrilled. Just thrilled."
Kagura's heart sank, his eyes drifting as he forced the words out.
In short, Sayuri had caught him with Ai, and the frequency—especially that weekend's twenty-one-round marathon—alarmed her. Fearing he'd ruin himself with youthful excess, she'd sidelined Ai to play butler and rein him in.
That weekend, he'd used a system "Triple Stamina Recovery Potion," harmless but not something he'd share. Telling anyone about his system was like a Harry Potter穿越者 bragging to Dumbledore about foresight—cringe-worthy.
"Right?! I think it's great too! Starting tonight, I'll work on my new ero-doujin: When My Husband Cheated, I Realized My Son Had Grown Up, So I…!"
Sayuri spun, pumping her fist with a "Let's do this!" gesture.
"Huh? What, what, what?!"
Kagura's urge to roast her skyrocketed.
"I hear you often give Eriri dialogue tips. Help me out too~"
"Wait, Sayuri, forget the cheating part—writing taboo incest smut in your son's room is already a massive issue!"
"No problem~"
"Where's the 'no problem'?! It's a huge problem!"
"I'm an adult, so I can handle it. You're under eighteen, so I'll keep the art out of sight~"
"That's not the issue!"
"Hm? What else is wrong?"
Sayuri tilted her head at a 45-degree angle, blinking innocently.
"Even without seeing it, it's still messed up!"
"Oh, you're right. Then I'll—"
"Not draw it, right?"
"Draw in Ai's room~!"
"That's still in my room! Wait, Sayuri, you're swapping rooms with Hayasaka?"
Kagura's hair stood on end.
She'd mentioned swapping roles. Did that mean calling Ai "Mom" for a month? Surely Sayuri wasn't that unhinged.
Ai would lord it over him, maybe even taunt him with a smug, "How's Mommy's pussy taste?" if he got too close.
No way, no way!
"Didn't you notice? Ai's stuff is already moved to a first-floor guest room—way comfier than this. I gave her a month's paid leave. She just bowed and said, 'Thank you, Madam.'"
"…Damn it, Hayasaka, you traitor!"
Kagura turned away, clenching his fists, "tears streaming."
Whack! Sayuri smacked his head, grabbing his earlobe and twisting. "Ai was your first, wasn't she? Cherish her, got it?"
"Got it, got it!"
Kagura shrank like a mouse cornered by a cat.
Who didn't fear their mom?
"And isn't it time you called her by her first name? Always 'Hayasaka'?"
"Uh… yeah, next time I see her."
It wasn't his choice—Ai insisted on "Hayasaka," claiming "Ai" gave her goosebumps.
"That's better!" Sayuri released him, hands on hips, appraising him. "Being young and virile isn't an excuse to overdo it. Instead of endlessly 'exploring life' with Ai, why not refine your piano skills? Even you'll get rusty without practice. I want you healthy, with moderation. Life's long—savor intimacy slowly…"
"Didn't expect a sex ed lecture at my age… Alright, I get it, stop pulling my ear!! Ow—!!"
Amid Kagura's wails, Ai, lingering outside, sighed, slipping away. "Good luck, Young Master. I'm under Madam's watch, my maid 'relief' duties stripped. You brought this on yourself with that wild weekend. Better make Yukino Yukishita your official girlfriend soon. And keep calling me 'Hayasaka'—'Ai' feels like stuffing a live sea cucumber down there."
"Ugh… my ear…"
Kagura rubbed it, whining.
"Ai's too obedient to you. I told her and Sora to guide you, but they're useless~ Should I replace Ai?"
Sayuri clapped, tilting her head with a "Not my problem~" look.
"Ai swore loyalty to me! You can't just swap her out!"
"True… Well, this month, I'm bringing a strict British governess to train Ai. Look forward to the results~"
Sayuri beamed, patting his arm.
Kagura could only force a dry laugh.
A governess teaching "feminine virtue"? No touching beyond hand-holding or kisses? Ai, good luck.
"Phew…" Sayuri's smile faded, leaning against the wall, arms crossed. "Sora's birthday is coming up…"
"April 24th."
Kagura recited it precisely.
(With slight setting tweaks, Sora's birthday shifted from February 5th.) Seeing Sayuri's melancholic expression—a strained, almost tearful smile—Kagura's heart ached. She stayed silent, lips pursed, gazing at him as if holding back sobs.
"What's… wrong?"
"Nothing… I adore Sora."
Sayuri dabbed a tear with her ring finger, forcing a smile.
"Everyone in the house can see that…"
Kagura's lips twitched, sighing.
Sora was less a maid and more a half-princess. Sayuri granted her every whim, and her "maid" duties were minimal—opening doors for Eriri, fetching someone, or passing messages. Without Sayuri's indulgence, Sora would be another Ai.
"You and Eriri shouldn't resent her."
"Never. Sora's prickly, but I care for her."
"Good… She's just a child, not at fault… but—"
Sayuri's fist clenched, her gaze drifting upward-left.
"But…?"
Kagura pressed nervously.
"Nothing~" Sayuri's tears vanished, and she circled him, sniffing lightly. Standing tall, she bowed slightly. "Young Master Kagura, it's time for dinner."
"…Sayuri, you're hiding something."
Kagura wasn't naive—her behavior screamed secrets.
Why urge them not to hate Sora but not Ai, despite their similar roles? Did Sora have some unique significance? And the birthday gifts for Sora were always grander than Ai's…
"Kagura, you must marry Mahiro Shiina."
"Not this again! I don't want to…"
Kagura's shoulders slumped, exasperated.
"No one's more suited to be your wife. Let's go eat."
Sayuri pushed him forward.
You might resist now, but once you know her, you'll change your mind. She's so pure, you could sleep with a dozen girls, and she'd be unfazed. A girl like that's perfect for a wife. You're still young.
"You're really playing butler, huh…"
"Of course! I'm serious about my duties. Ai starts training tomorrow, and you'll need someone in the meantime. Or should I assign Sora to you and serve Eriri?"
Kagura nearly blurted, That'd be awesome! but stopped—Sayuri had chosen him, and dismissing her would be cold. He shook his head. "Get someone else! Not Sora. Just be the idle duchess, isn't that better?"
"No~~ way. No other girl can handle you. This month, I'm eating and living with you!"
"What about Dad? He'll skin me!"
"Him?" Sayuri snickered, voice gleeful. "I haven't slept with him in seventeen years. I'm tighter than a chopstick slot, so don't worry~~"
"Don't casually spill your marital sex life and personal state to your son—!!"
Kagura covered his ears, yelling.
But then it hit him: Seventeen years?
That meant… since conceiving him and Eriri, Sayuri hadn't been intimate with his father?
What happened between them? Coupled with her doujin title and Sora comments, a suspicion formed.
Tonight, he'd call his dad for answers.
