The interior of the built-in wooden closet was pitch black.
Nana Astar Deviluke stood rigidly in the darkness, her slender body pressed intimately against her twin sister. There was absolutely no room to manoeuvre. Every time she inhaled, her chest brushed against Momo's, and she could feel the rhythm of her sister's heartbeat against the wild beats of her own frantic heart.
Nana's heart was hammering against her ribs so violently that she genuinely feared the deafening thump-thump-thump would echo right through the wooden doors and alert the girls standing in the bedroom outside.
Through the narrow, slatted louvers of the closet doors, Nana's wide, trembling violet eyes were locked onto the dimly lit scene unfolding just a few feet away. The moonlight filtering through the bedroom window cast long, pale shadows across the tatami mats, illuminating Rito's bed perfectly.
Initially, when the bedroom door had opened and Mikan stepped inside, a wave of relief had washed over the Second Princess.
'Thank goodness,' Nana had thought, her tense shoulders slumping in the dark. 'Mikan is here. She's the sensible one. She'll probably yell at this perverted beast for making so much noise in the middle of the night, and then leave with her two friends, after that, Momo and I can escape this humiliating box.'
But that comforting illusion was soon shattered.
Nana watched, completely paralyzed, as Sachie leaped through the air, bypassing Mikan entirely, and practically tackled Rito onto his back.
Without a single shred of hesitation, Sachie aggressively crashed her face into Rito's, mashing her lips against his in a frantic assault.
Chuu... slurp... mwah!
The wet, sloppy sounds of their mouths colliding and their tongues aggressively wrestling echoed in the quiet bedroom.
Sachie was grinding her pajama-clad hips shamelessly against his lap, letting out soft, needy moans directly into his mouth as she devoured him.
Nana's jaw dropped so hard it nearly unhinged. Her violet eyes bugged out of her skull as she witnessed the scene devolve into pure degeneracy right before her very eyes.
If Sachie's sudden attack was shocking, Mami's actions completely broke Nana's brain.
The quiet, seemingly timid girl crawled onto the other side of the futon, and picked up Rito's left hand, bringing his index and middle fingers directly to her lips. She parted them eagerly, taking them deep into her mouth with wet, sloppy suction.
Gluck... schlorp... mmm...
Mami's cheeks hollowed out as she sucked on his fingers like lollipops, swirling her tongue around them in a display of intense lust. And if that wasn't enough, Nana watched in horror as Mami used her free hand to reach down, hiking up the leg of her yellow pajama shorts to slip her fingers directly into her own crotch.
Schlick... squelch... schlick... squelch...
The sticky sounds of Mami actively masturbating her own soaking wet pussy right there on the bed, using the taste of Rito's fingers to fuel her frenzied rubbing, filled the air.
Nana's face burned with a heat. Steam practically poured from her.
She had always called Rito a beast. Ever since they first arrived on Earth and he had accidentally walked in on them bathing, she had labelled him a pervert. But that wasn't a misconception; she continued calling him that because he was a pervert. He already had a sprawling harem, and he was quite vocal about his lecherous desires. He never tried to hide the fact that he was wildly attracted to the women around him.
But seeing this... seeing these supposedly innocent girls turn into ravenous, drooling predators attacking him... it was too much.
'What the hell?! Stop it right now!' Nana screamed internally, her hands curling into tight fists at her sides. 'Mikan! Do something! Tell them to get off him!'
Nana waited for Mikan to stop it, praying for the voice of reason to intervene and restore order to the household.
Instead, the sharp, metallic sound of the bedroom door locking pierced the air.
Click.
Nana watched, her breath catching in her throat, as Mikan turned away from the locked door. The younger sister didn't look angry or annoyed. Rather, a soft, deeply affectionate, and unmistakably possessive smile spread across Mikan's lips as she walked over and climbed onto the mattress, positioning herself near Rito's waist.
Nana's eyes widened to impossible proportions as her mind raced, instantly visualizing the implications of what was about to occur. Mikan wasn't stopping them; she was joining them.
Beside her, in the confines of the closet, Momo Belia Deviluke was experiencing an entirely different feeling.
Having previously peeked once and watched Rito breeding Mikan for hours on end, Momo was far more knowledgeable about the true, terrifying extent of Rito's charm, his harem dynamics, and his monstrous sexual prowess. She knew exactly what that beast-like stamina looked like in action.
And right now, being trapped in his closet while watching it all unfold again was sending her into a state of excitement.
Momo leaned forward, resting her chin delicately on Nana's trembling shoulder. She intentionally pressed her body closer, allowing her soft, pillowy breasts to squish deliberately against Nana through the thin fabric of her nightgown.
"My, my," Momo whispered directly into Nana's pointed ear, her voice a sultry, ticklish purr that sent shivers racing down Nana's spine.
"Look at how popular our dear brother-in-law is, Nana," Momo softly narrated the lewd acts happening on the bed, her breath hot against her twin's skin. "Sachie-san is kissing him so deeply... and just listen to Mami-san. She's completely soaked for him. And Mikan-san didn't even scold them... she locked the door. It seems, she wants him too."
Nana clamped her lips shut.
"Tell me, Nana," Momo continued, her hand slowly sliding up to gently trace the curve of Nana's waist in the dark. "Watching him get jumped so passionately by his own sister and her friends... hearing those wet, lewd sounds... does it make you feel something? Is your heart beating fast because you're angry, or because you're... curious?"
Nana's blush deepened. She was trapped, wedged between her sister's corrupting whispers, and the live spectacle taking place just feet away in front of her.
Meanwhile, on the bed.
Yuuki Rito was completely trapped under the eager, soft weight of Sachie and Mami.
Physically, his body was roaring with blinding pleasure. The sensation of Sachie aggressively pushing her tongue into his mouth, tasting of sweet saliva and desperate need, combined with the wet suction of Mami's lips pulling on his fingers, was overloading his system.
But mentally, Rito's mind was in a state of panic.
He was aware of the closet doors situated just a few feet away. He knew for a fact that Nana and Momo were watching.
The weight of this involuntary exhibitionism was staggering. Being serviced by his little sister and her mischievous friends while the two Devilukean princesses observed him from the shadows of his own wardrobe... it was a scenario so wild, so degenerate, that it bypassed all of his usual anxiety and struck directly at his core.
It caused his arousal to skyrocket.
Beneath the thick duvet, his erection surged, hardening to the density of steel. It throbbed painfully against the restricting cotton of his boxers, the thick veins pulsing with every frantic beat of his heart.
The intense stimulation and the thrill of the hidden audience pushed his body to react. A steady, heavy stream of thick pre-cum began to leak from the flared head of his shaft. The clear, viscous fluid seeped through the fabric of his underwear, rapidly creating a visible wet spot right on the front of his boxers.
Mikan, having settled onto the mattress, crawled to the exact center of the bed.
She looked down at Rito's face, and reached out, gently placed her hands on Sachie's shoulders, separating her from Rito's lips.
Mikan reached down with her thumb, tenderly wiping a thick, glistening string of saliva from Rito's chin.
"You two are too impatient," Mikan scolded them softly. However, despite her words, her voice lacked any real reprimand; instead, it was thick, husky, and dripping with her own rapidly rising lust.
Without a single shred of hesitation, shyness, or shame, Mikan reached down and grabbed the hem of her loose pajama shirt. In one fluid motion, she pulled the garment up and over her head, tossing it carelessly onto the floor beside the bed. She slipped off her bottoms just as quickly, kicking them away.
She sat back on her heels, resting in the center of the bed, completely bare.
The pale moonlight streaming through the window fell perfectly across her body. It caught the smooth curves of her hips, the delicate swell of her small breasts, and illuminated her flat stomach.
There, resting just below her navel, the Golden Heart Seal caught the lunar light. It began to pulse with a warm, steady, amber glow, a beacon of her eternal bond radiating in the dim room.
Inside the cramped closet, Nana's breath hitched violently in her throat. Her violet eyes widened as she spotted the glowing proof of Mikan's bond to her brother.
Mikan didn't wait for Rito to recover his breath.
She leaned down, hovering over his face, her hair falling like a curtain around them. She captured Rito's lips in a deep, passionate kiss.
As their tongues wrestled in a wet, possessive dance, Mikan's small, pale hand slid slowly down Rito's stomach. She bypassed the blanket entirely, her fingers finding the large, damp spot on the front of his boxers.
She didn't bother pulling the fabric down. She simply gripped his rock-hard, leaking shaft firmly right through the wet cotton of his underwear.
Squeeze.
Mikan gave his massive erection a tight, possessive, agonizingly good squeeze, her thumb rubbing directly over the sensitive, flared ridge of his head through the damp fabric.
"NNNNGGGHH!"
Rito groaned loudly directly into her mouth. His hips bucked violently upward off the mattress, his body arching as the intense, direct stimulation, completely forgetting about the audience in the closet for a split second.
Mikan slowly pulled back from the kiss, a wet smacking sound echoing in the room. Her gold-brown eyes were heavy, lidded, and swimming with a dark, insatiable lust.
She looked down at Rito's flushed, desperate face, a wicked, loving smile spreading across her lips.
"It's time to have a real 'sleepover', onii-chan," Mikan whispered.
"Yes! A real sleepover!" Sachie chimed in enthusiastically.
"We want to feel onii-chan too..." Mami added, her voice trembling with anticipation.
Without another word, Sachie and Mami scrambled to their knees on the mattress. They grabbed the hems of their own cute pajama sets and pulled them over their heads, tossing them aside to undress completely, baring their eager bodies to the moonlight and to him.
Trapped under the weight of three naked girls, with his erection leaking through his boxers and his future sisters-in-law watching from the shadows of his wardrobe, Yuuki Rito braced himself for the incoming mind-melting night.
