"Lift your T-shirt so I can see."
Eriri strode up to Kagura, not waiting for him to comply before boldly reaching out.
She yanked up the hem of his T-shirt, and upon noticing his drawstring pants, swiftly tugged the cord loose with a whoosh.
"Whoa, what?!"
Kagura's eyes widened in alarm.
"What's with the 'what'?! Just shut up and stay still!"
Eriri's cheeks flushed as she shot him a glare. She unraveled the drawstring completely, crossed it once, and pulled it tight with a fierce tug.
"Damn, damn, damn—are you trying to strangle me?!"
"Quiet, quiet! You're a guy, aren't you? Can't handle a little tightening?"
Panting slightly, Eriri cinched the drawstring as tight as it would go, securing it with a dead knot, leaving Kagura utterly bewildered.
"Ugh—" Kagura groaned, rubbing his now-constricted waist and rolling his eyes. "So, what's the point of yanking your brother's pants open just to tie them tighter?"
"Hmm…"
Eriri lifted his T-shirt again, attempting to slip her fingers into his impossibly snug waistband, but it was too tight. She then tugged at his pant legs, which, predictably, didn't budge.
Clap, clap, clap. Eriri puffed out her chest triumphantly. "Alright, now we officially begin."
"Begin what?"
Kagura was thoroughly confused.
"Obviously, you're going to be my drawing assistant! What else?!"
Eriri turned her head, biting her lip as if it were the most obvious thing in the world.
"??? Be an assistant, fine, but why the hell did you need to strangle my waistband?"
"Ugh, stop yapping and follow me!"
Eriri shook her head impatiently, grabbed Kagura, and led him through the maze of easels to a corner of the studio. There stood a massive mirror, no smaller than the one in the Service Club room on the fifth floor of the old school building. Framed in dark bronze with imposing lion-claw supports, it exuded grandeur.
The mirror's rectangular surface, with gently rounded corners, gleamed spotlessly, perfectly reflecting Kagura's striking features and Eriri's delicate visage.
Eriri released his hand and stepped in front of him.
At 155 cm, Eriri was nearly 30 cm shorter than Kagura's 182 cm, her head barely reaching his chin. Her petite frame made her look like a miniaturized version of him when they stood side by side.
But one thing stood out undeniably—
Her hips were remarkably shapely, round and perky. Kagura would bet that fewer than three women in the household could rival Eriri's hip measurements; Sora and Ai didn't even come close.
"Looking at us like this, it's kind of surreal… We're twins, but we don't look alike at all, and one's a guy, one's a girl. You grew into this useless giant."
"Hey, is that how you talk about your brother? It's called fraternal twins."
"I know that!" Eriri spun around, glaring. "I didn't skip health class!"
"Oh… then you must've aced it~"
Kagura smirked with a knowing undertone.
Health classes were split by gender, and as a kid, Kagura had been curious about what the girls learned. That curiosity faded when Ai gave him a hands-on "health education" later on.
"Hmph!" Eriri scoffed, turning away. She gathered her golden twin-tails in her hands, gently shaking them. "So, what do you think? Pretty, right?"
"Oh, stunning, adorable, absolutely to die for—"
Kagura drawled monotonously, devoid of enthusiasm.
"Don't give me that robotic delivery!"
Eriri stomped on his shoe in retaliation.
"Ow, fine, so what do you actually want me to do?"
"Uh… well…" Eriri faltered, forcing herself to face the mirror again. She lifted her hair and passed it back to Kagura. "Hold it carefully."
"Alright…"
Kagura gently lifted her hair from below, cradling it softly in his palms.
Even this simple act made Eriri's cheeks burn, her toes curling in embarrassment.
Kagura knew how much Eriri treasured her golden locks. Though she didn't fuss over them at home, no girl—unless she had a pixie cut—would neglect such silky, flowing hair.
"So… what do you feel?"
"Soft, smooth, a bit cool, and when I smell it…"
"Don't smell it, you creep!"
"You said to 'feel' it, so shouldn't I use all five senses?"
"Fine… fine… ugh—then what's it smell like?"
"You've been using that tulip shampoo, right? Smells like tulips."
"Ugh, you…" Eriri turned slightly, stomping her foot in frustration, her eyes narrowing. "I meant the natural scent of a maiden's hair that only a perv could pick up, not the shampoo!"
"Oh, come on, I'm not a perv! Why would you think your brother could sniff out some creep-only scent from his sister?"
"Th-that's… ugh! I don't believe you! No guy's not a perv! You're hiding something! Just admit it—I'm your sister, I won't judge!"
"…Get lost!"
Kagura considered nudging her hips with his knee but, standing so close, opted to thrust his waist forward instead. Eriri yelped, her hips bouncing against his thighs—soft, springy, and perfectly curved.
"You—you—you jerk, what the hell?!"
Eriri clutched her backside, turning slightly to glare, careful not to yank her hair still in his grip.
Kagura rolled his eyes, stifling a laugh, though his lips betrayed a persistent smirk. Eriri's expression turned scornful as she muttered, "You're grinning like a victorious creep and still claim you're not a perv…"
"Alright, what do you want me to do?" Kagura sobered up, smoothing her hair. "Are you the perv who gets off on having your brother touch your hair?"
"Look who's talking! Reflect on yourself before accusing me! Bumping your sister's hips like that—what were you thinking?"
"Yes, yes, I'm guilty, I repent, happy now?"
"See? Guilty! I knew it!"
"Keep stalling, and I'll bump you again."
"Fine… ugh…" Eriri's bravado fizzled. She covered her face, then straightened, eyes closed in the mirror's reflection. With a barely perceptible nod, she whispered, "Go ahead… bump me again."
"Huh?!"
"I called you here for this!" Eriri spun around, flustered. "I-I need to draw that kind of scene, you know?! That moment! I don't know what expression the heroine should have! I need your help!"
"What scene? What moment?!"
Kagura was lost, suspecting it was something risqué but wary of misinterpreting and earning her wrath.
"You—you—how dare you question me?! Don't you have a… you know?!"
"I'm pretty sure you've seen it!"
"Ew, what?! Oh… that's not the point!" Eriri pivoted, closing her eyes and shyly brushing her hips against his thigh. "It's… this feeling, got it?"
"Uh… you mean you want to experience the heroine's first-person perspective, right?"
"Thank goodness you get it, you dense brother," Eriri said, patting her chest confidently. "Exactly. You'll use my twin-tails like handlebars, ram my hips from behind like I'm a human cart, and I'll study my expressions in the mirror. Clear?"
"Clear… my ass! Bumping my sister's hips once is weird enough, but repeatedly?!"
"Didn't you suggest it?!"
Eriri's face burned, mortified.
"I was joking! Who knew you'd take it seriously?!"
"Enough talk—just do it! Are you doing it or not? If not, I'll tell Mom you… you… yeah, that you watch porn!"
"You, who draws dirty manga, have the nerve to call me out?!"
Kagura's retort left Eriri speechless. She flicked her twin-tails free from his grasp, faced him, and gripped his T-shirt. "You got sent to the infirmary today, and I was the only one who checked on you—not even the doll girl. You owe me for that, don't you?"
"…I've got no comeback. Since when did you get so cunning?"
"Are you doing it or not?"
"You could practice this with Sora."
"How could I face Sora after that?! Get real, you idiot! I'd never live it down!"
"But you're fine asking me?!"
Kagura covered his face, mortified.
"Yeah, I asked you, so what? Are you doing it or not?"
Eriri was on the verge of tears, her voice trembling with shame and urgency.
Unable to bear her distress, Kagura sighed and nodded. "Fine, better me than someone else."
"See? Was that so hard? Stop whining!"
They stepped back slightly, aligning in front of the mirror. Eriri gave a small bow to her reflection, adjusting her distance for optimal viewing, then straightened, blushing as she took deep breaths. "Alright… start."
"Okay… okay!"
Kagura's hands glided over her shoulders, gathering her hair—left, then right—into a single bundle.
"Not… not too tight."
Eriri's voice was soft, cautious.
Kagura loosened his grip, and Eriri leaned forward, shifting from pressed against him to a roughly 45-degree angle.
Her hair slid through his palms until, near the mid-length, she held her pose, and he tightened his hold.
From this angle, Eriri's waist dipped, her head tilted up, and her rounded hips pressed against his thighs. She wore her Sobu High uniform, not gym clothes, making Kagura hyper-aware that her skirt could flip up at any moment, revealing her panties.
"Why… why are you just standing there?"
"I'm wondering if I need some prep—mental or otherwise."
"We're not actually doing it! You need foreplay for this?! Just move already!"
"Ugh…" Kagura muttered, stepping back slightly, then thrusting his hips forward. "Fine, lift your heels, push your hips back, and press them against my crotch."
"What the hell are you saying?!"
Eriri's face blazed, unable to turn fully but glaring at him through the mirror with a sidelong glance.
"You're too short! If you're drawing this, it's gotta match real positioning, right? If the rod and hole don't align, what's the point?!"
"Shut up! Fine… I'll do it!" Eriri grumbled, calling him a "meddlesome virgin."
"Pot calling the kettle black! Like you're not one!"
"Shut it! I'm a proud virgin! There, I'm up!"
As instructed, Eriri pushed her hips back, standing on her toes to align with Kagura's crotch. Unsteady, she leaned further forward, but his grip on her hair tugged painfully, making her hiss.
Kagura stepped closer, steadying her hips with his own, his sweaty palms tightening on her hair. Looking at her flushed, averted face, he said, "I'm gonna start."
"…Hurry up! Be a beast—don't treat me like a person!"
Eriri's voice was barely a whisper, urgent.
Kagura leaned back, wrapping her hair once around his hands to keep her steady, then rocked his hips forward, setting hers in motion.
Finding a rhythm, he thrust firmly, then pulled back. Eriri's hips rippled from the impact but snapped back due to her stance, meeting his returning thrust. They collided repeatedly—thud, thud!—in sync.
"Ughhh…"
In the mirror, Eriri's face glowed red, almost dripping with embarrassment. Kagura felt a twinge of shame too; this was his sister, yet he was making her hips clap audibly, his erection painfully obvious. The sensation of his shaft pressing against her soft flesh was overwhelming, despite his efforts to ignore it.
His body screamed that her core was just beyond, urging him on.
Kagura's stamina was exceptional, and with Eriri's "don't treat me like a person" ringing in his ears, he unleashed his inner beast. His grip tightened, his thrusts grew faster and harder, and Eriri's soft moans—half-pain, half-pleasure—escaped as she struggled to cover her mouth while forcing her eyes open to study her disheveled reflection.
Eriri had long sensed Kagura's erection pressing into her cleft with each thrust. His shaft, fully upright and pressed against his abdomen, would've snapped otherwise. Every collision drove it deeper into her seam, and she wondered if she should feel ashamed.
She was ashamed—mortified—but not just because of his arousal. The real shame was how much she was enjoying this rough treatment: hair pulled, hips slammed, posed lewdly. She was soaking wet, her excitement mounting with each tug of pain, her clit rubbing against her panties, pushing her to the edge.
"It hurts… hurts… Kagura-nii… your cock, so big, it hurts…!"
Eriri leaned into the act, playing the part fully. Seeing herself spout such shameful lines in the mirror, her arousal spiked, her juices seeping through her panties and trickling down her thighs.
"What?! I'm not even inside!"
Kagura jolted at her brazen words, glancing at his crotch. His erection strained high, but it hadn't pierced his pants!
"Please, be rougher… ruin your filthy sister Eriri's slutty hole! Front or back, be a beast, stretch me until I can't close, and even then, don't stop… fill me with your cum, burn my womb…!"
Eriri, shame cast aside, recited lines straight from her explicit manga, lost in the moment.
"Holy—go to hell!"
Kagura released her hair, instead grabbing her waist and lifting her. Her upper body sank, and he handled her like a life-sized doll, slamming her hips against his crotch. Gripping her tightly, he thrust aggressively, growling, "I'll wreck you, you blonde, sharp-toothed little slut!"
"Yes, like that! I'm sorry, I'm sorry! I'm a fake good girl, dreaming of being fucked senseless. Keep going, Kagura-nii, punish my disobedient, dripping hole with your cock, hammer my cervix with your tip, flood me with your thick, hot cum, use me like a worthless flesh toy!"
As Eriri spoke, Kagura's thrusts didn't falter. By the time she finished, he was on the verge of release. Good lord, girls could be this wild? Ai rarely spoke like this, but Eriri…
Subway, old man, smartphone.
The moment her words ended, Kagura felt her tremble violently, her body quaking from her lower half outward. Her legs stiffened, her hands twitched, and he knew what was happening. He wrapped his left arm around her waist, his right around her chest, pulling her upright, pressing his shaft firmly against her cleft. His right hand brazenly kneaded her left breast.
Eriri's spasms lasted a long while…
She seemed dazed, turning back to touch Kagura's face, nearly rising on her toes for a kiss before snapping back to reality.
"…??"
Eriri blinked, locking eyes with him.
Kagura, breathing deeply to calm himself, realized he'd briefly seen her not as his sister but as a submissive masochist he craved to dominate harshly.
"You… can let go now…"
Eriri glanced at his arms around her waist.
"…Ahem."
Kagura released her. She wobbled to a nearby cushioned bench, tugging her skirt down and staring at him with a flushed, silent accusation.
"You—"
"Shut up!"
Eriri glared, cutting him off.
Kagura wanted to ask, "You just came, didn't you?" She knew his intent and refused to let him voice it—admitting or denying it would be too mortifying.
"Uh… fine." Reading her mood, Kagura sat beside her, draping an arm around her shoulders and breathing deeply. "You're turning me into a perv."
"Nonsense. You were already a perv; I just drew out your filthy desires."
"You heard the crap you just said…" Kagura grabbed her right hand, pressing it against his erection. "This why you tied my drawstring so tight?"
"N-no choice, okay?!"
Eriri yanked her hand back like she'd touched something foul, shaking it before primly resting it on her skirt. "I was just researching, simulating the real thing! Who knows if a guy's animal instincts would take over? Better safe than sorry—I'm your sister! What were you thinking?!"
"Fair point…" Kagura exhaled, pointing to his still-rigid shaft. "So, dear sister, what do I do about this?"
"None of my business! How should I know what to do with… that thing?!"
Eriri covered her face.
"You got yours, so I deserve something too, right?"
"W-w-what?! Don't make stuff up! I never said I… stop dreaming and get back to your room!"
"Hah? Last time aside, you teased me into a frenzy today. Don't you owe me?"
"Ugh, gross! Asking a girl to take responsibility?! I'm your sister! Pervert, disgusting, depraved creep! Your words gave me goosebumps!"
Eriri hugged herself, shuddering.
"I don't care. You're settling this today, or else…"
"Or… or what?"
Eriri shrank into the corner, muttering rapidly, "You gonna say, 'You're a woman, sister or not, you're responsible for my virginity,' then pin me down, rip my shirt, grope my chest, and tear off my panties? Even if I scream, 'No, we're siblings, we can't!' you'll roar, 'This is your fault, take responsibility!' and force off my underwear, and while I resist, you'll poke me and shove that stinking meat stick in my mouth, right?"
Kagura's head buzzed from her rapid-fire words—how could girls talk so fast, like a machine gun? But her vivid scenario stirred him. He took a sharp breath. "Is that what you think about all day?"
"I'm not thinking it! I'm just describing your twisted mind!"
"Ugh, useless sister." Kagura adjusted his clothes, smoothed her hair, and leaned in. Eriri yelped, clutching her collar, but he only kissed her forehead, whispering, "I was so happy you came to check on me today. Thank you. I'll always love you. Good night."
He headed for the door.
"Ughhh…"
Eriri's mind short-circuited, torn between calling him back and letting him go禁止使用或传播;不得用于商业活动;不得抄袭或洗钱;请勿从事非法活动或违反国家法律法规的活动.
She trailed after him, grabbing the back of his T-shirt.
"Hm?"
"Just… let me borrow you for a sec…"
"What?"
"Close your eyes, don't move, stay right there!"
Eriri, blushing, pointed at his face imperiously, her left hand on her hip.
"Ugh, enough games, I'm going."
"Hurry up! Don't you love me forever?"
"Already exploiting that love, huh?!"
"Spend less time whining and close your eyes!"
Reluctantly, Kagura obeyed, standing still.
Eriri waved a hand in front of him, ensuring he couldn't see, then darted to a corner cabinet. She opened a drawer filled with clean panties—extras for when her drawing sessions got intense and soiled her current pair.
Swiftly, she swapped her soaked white panties for a fresh pair, closed the cabinet, and tiptoed back to Kagura, balling the used ones up and handing them over. "Okay, open your eyes."
"…?"
Kagura instinctively reached out.
"Before I give you this, one condition!"
"Name it."
"Absolutely, absolutely no sniffing! Or I'll kill you!"
"Got it…"
Kagura extended his right hand.
Eriri turned away, releasing the soft, still-warm panties into his palm.
The moment they touched, he felt the slick moisture. He glanced at Eriri, who spun around, hands on hips. "Hmph! Don't say a word, or I'll take them back!"
"So… you're saying I should use these to take care of things?"
Kagura held the panties by their edges, stretching them slightly, then brought them close to his nose for a deep inhale.
Ah… that scent. Addictive.
"Y-yeah! You'd do it anyway, right?"
"Well, guess I'll make do." Kagura balled them up, pocketing them. "I'm heading back."
"Wait, hold it! Where are you going?"
"To my room to 'handle it'?"
Kagura turned, puzzled.
"No way you're taking those out of here!" Eriri, face flaming, pointed to the bench they'd sat on. "Go sit there and do it while I watch."
"What—?!"
"Do it, or give them back!"
"Fine…"
Kagura caught on. Her goal hadn't changed—she wanted to see him jerk off, but now she'd added hip-bumping to the mix.
Kagura rarely masturbated; Ai had helped him dozens of times, though not hundreds. Usually, he'd pleasure her while she stroked or sucked him, sometimes wrapping his shaft in her panties.
He pictured kneeling on a bed facing Ai's side, her upper body bare, her maid skirt hiked up. She'd grip his cock through her warm panties, stroking until he was close, then remove them, letting him spill onto her skirt.
Honestly, it rivaled full-on sex with her.
Kagura sat on the bench, struggling with the dead knot for ages. When he finally loosened the drawstring, he saw deep red marks on his waist, but that didn't matter. He slid off his underwear, freeing his massive erection.
Eriri stared, unblinking, grabbing a pencil and sitting by a nearby canvas.
"Start… start…"
Eriri swallowed hard.
Kagura took her drenched panties, soaked from her climax, and wrapped the stickiest part around his shaft, stroking with his right hand.
Eriri sketched furiously, more focused than when she watched cartoons as a kid.
Ten minutes later, Kagura groaned, unloading onto the white panties with their black bow, coating them.
Eriri caught the pungent scent of semen, which only heightened her arousal, dampening her fresh pair.
Trembling, she set down her pencil. "That… that's enough, right?"
"Yeah… barely."
It wasn't enough, but pushing his sister further wasn't right. Kagura used her panties as a tissue, wiping his shaft before holding them, unsure where to discard them.
Eriri rummaged for a clean white plastic bag, hurried to his side, and held it open. "Toss… toss it in here. I'll seal it and throw it out."
"Cool."
Kagura dropped them in, pulled up his pants, and exhaled deeply.
"You… in sage mode now?"
"Sort of…"
"You're young—can't go another round?"
"Jerking off isn't my thing. Today was an exception for you."
"Don't make it sound so gross! You got yours, now get lost!"
Eriri hauled him up, shoving him out of the studio.
Once he was gone, Eriri eyed the plastic bag, swallowing hard. Like a ravenous wolf, she pounced, untying it in seconds. Carefully, she opened it, dipping a trembling fingertip into a still-warm drop of Kagura's semen and sniffing it under her nose.
"…Ugh! This smell!"
So gross… yet somehow enticing…
Conflicted, Eriri couldn't resist. She slipped her fingertip into her mouth, licking it clean with her tongue.
"Not… that bad, I guess… kinda salty, lewd."
Muttering, Eriri knelt on the bench, opened the bag wide, and buried her face in it, licking every drop of Kagura's semen—and her own juices—clean.
That night, Eriri pleasured herself relentlessly until dawn, still craving more when breakfast time rolled around.
Wednesday morning, Sora, face dark, pushed open the partition between her and Eriri's rooms. Half-hidden by the door, she said, "Eriri, enough already… You don't sleep, fine, but I need rest."
"…"
Eriri curled up in her blankets, pretending not to hear.
"Don't play dead. Think your act fools me? You going to class today or not?"
"Going…"
Eriri mumbled pitifully.
"Then hurry up and wash that stench off your body."
"…"
Eriri shrank, humiliated.
At school, Kagura found Yumiko waiting at the gate, her eyes locking onto him the moment he stepped out of the car. With no choice, he approached. "Morning. What's up?"
"You… you…" Yumiko scanned him head to toe, then sighed in relief. "Everything okay after… that?"
"All good, thanks to your 'curse-breaking' technique."
Kagura winked, glancing at her red lips.
"Idiot!" Yumiko blushed, glaring, then whipped out her phone. "Hand over your number, email, LINE QR code—everything."
"Whoa, thought you were robbing my wallet."
"Are you dumb? What kind of person do you take me for?!"
"Hahaha…" Kagura laughed, handing her his phone. "You do it."
"Oh… oh…" Yumiko, startled, took it, incredulous. "You're so trusting? What if someone messes with your phone or snoops?"
"No worries. I trust you, Yumiko-nee."
"Huh? Oh… well, fair enough…"
Flattered, Yumiko deftly inputted their contact info, swapping details with both hands.
Sora and Eriri passed by, Sora side-eyeing Yumiko, while Eriri gritted her teeth. Sora murmured, "Who's that?"
"Class F, Yumiko Miura."
"She's… annoying."
"No need to tell me—I feel the same."
"Really…?"
Sora, unsurprised, hummed softly and walked hand-in-hand with Eriri toward the school building.
"So… sleepy."
Eriri yawned mid-stride.
"Your hands clean, Eriri?"
"What the hell are you implying?!"
Eriri jumped, caught off guard.
"I don't want to touch your… fluids."
Sora whispered in her ear.
"They're clean!"
"Good enough…"
Sora tightened her grip on Eriri's hand.
"Seriously, when did a mere maid get so cocky?"
"Want to hold my hand after I've touched myself, all sticky?"
"No way! What's wrong with you, idiot?!"
Eriri, uninterested in girls, shuddered at the thought.
"Exactly. Don't push others to do what you wouldn't."
"…"
Eriri slapped her own face, nodding, red-faced.
"By the way," Sora whispered, "how many times last night?"
"You're seriously asking?!"
"Telling me won't hurt. I won't spill. It's just… you going that hard is rare, so I'm curious."
"Curious? Try it yourself all night. We're both girls—shouldn't be much difference."
"Eh… really?"
Sora didn't press, just smirked mischievously, then reverted to her usual indifference, pulling Eriri into a light jog.
It was Wednesday, with PE in the afternoon. Kagura was physically capable (in combat skills), but sports weren't his forte, having poured his talents into music over athletics or art. So, with Hachiman's suggestion, they chose tennis, which seemed less demanding.
Sobu High's PE classes mixed two classes, but genders were separated. Kagura brought his inowater bottle. While other boys reeked of sweat post-class, Kagura stayed odor-free, thanks to a system perk he greatly appreciated.
Near the net, he sipped from his bottle when the teacher called out, flipping through the roster. "Sawamura Spencer Kagura, who's that?"
"Here!"
Kagura raised his hand.
"You and Hikigaya Hachiman are on cleanup duty this class. Gather the rackets and gear and take them to the sports storage."
"No problem!"
Kagura waved, catching Hachiman's eye. They exchanged shrugs and a grin, swiftly collecting rackets and balls, stuffing the balls into a mesh bag and the rackets into cases. Hachiman took the balls and some rackets, while Kagura carried the rest, his half-empty drink tucked under his arm, as they strolled to the storage room.
"Your stamina's insane…"
Hachiman remarked halfway.
"Decent, I guess. Got forced to train a lot as a kid—not fun."
"Got it. Still, I'd take a chill childhood any day."
"Right? I'm kinda jealous of you."
"Shut up…"
"Haha, I'm serious. By the way, isn't there a career internship thing late April, second year?"
Under the blazing sun, Kagura felt comfortable, likely another system perk keeping his body temp steady.
"Yeah… you got a place in mind?"
"Me? I'm aiming to be a pianist. Where would I intern? Japan Piano Association? Get real."
"Fair point, you…" Hachiman coughed, sighing. "Honestly? I want to be a househusband."
"Nice. Just need a hard-working or loaded wife, or it's tough."
"I know, but my headache's the internship. Where do I 'intern' for househusband?"
"That's a tricky one…"
"No ideas either, huh? Guess I'm in for more headaches."
They stepped into the sports storage, found the tennis gear spot, and dumped the class's equipment. Clapping their hands, they turned to leave.
