Excuse 1
Haruna lay in bed in her room, staring wide-eyed into the darkness all night long. The events of the previous night wouldn't leave her mind. Her own image, seducing her little brother while acting as the succubus 'Harona'. She told herself over and over that it had all been an act, but the sensations etched into her body didn't lie. Dojin's firm body, his rough breaths, the hot fullness that had filled her completely. Waves of guilt and shame crashed over her, but at the deepest core of those waves lingered the stubborn afterglow of an intense pleasure she'd never felt before.
'I'm... the worst sister ever.' She pulled the blanket over her head. She kicked at it with her feet. But even in the darkness, Dojin's face appeared vividly. Those eyes that had trusted her so purely. She didn't have the courage to face them.
Knock knock.
"Sis, get up. Time for breakfast."
Dojin's voice from beyond the door made Haruna's heart sink with a thud. How should she face him? What should she say? Her mind went blank.
"Uh... yeah. I'll be out soon."
With a trembling voice, she barely managed a reply and dragged herself out of bed. Every step made her lower body throb. Traces of last night's intensity. As she showered, she steeled herself.
'Right, this is a secret. A horrible secret I have to keep to myself.' She had to act like nothing happened, return to being the rational, mature big sister. That was the only way to preserve this fragile family peace.
When she stepped into the living room, the whole family was already gathered around the table. An Hyeonmi was simmering doenjang jjigae in the kitchen, and Harina, fresh from her workout, was chugging water with flushed cheeks. At the head of the table sat Hadojin, smiling brightly as if he knew nothing.
"Sis, slept in, huh? Did you drink too much wine last night?"
Dojin's teasing words made Haruna's face burn.
"N-no... just tired."
She forced a casual tone and sat down. But every time their eyes met, fragments of last night flashed back, making her heart plummet.
"Alright, everyone, breakfast time. Luna, come sit."
An Hyeonmi placed the steaming pot in the center of the table. The savory aroma whetted appetites, but Haruna could barely swallow.
"Sis, now that you're unemployed, let's work out together every day!"
Harina's eyes sparkled as she said it.
"Give me a break, Rina."
"Come on, it's fun together! Oppa teaches boxing, and it's amazing! I feel way stronger than yesterday!"
Harina excitedly recounted her training. Her gaze was fixed entirely on Hadojin—not mere admiration, but the hot look of a woman eyeing a man. Watching it, Haruna felt a chill in her chest.
Harina too... with Dojin.
'No. Harina's still too young.' Separate from her own sin, her instinct as the eldest sister to protect her rose up.
Ring ring ring~ Ring ring ring~
Then, her phone rang from Harina's room, and she jumped up.
"Oh, gotta hit the bathroom quick!"
"You done eating?"
"No! I'll eat more after!"
With Hadojin and Harina gone, only An Hyeonmi and Haruna remained. An Hyeonmi ladled jjigae into Haruna's empty bowl, speaking softly.
"Luna..."
Haruna looked up. Her mother's face held not the usual gentle smile, but a cool expression that seemed to see through everything.
"Yes?"
"That must have been tough."
An Hyeonmi's cool gaze softened again as she stroked Haruna's shoulder.
"I'm okay now. I quit the company, and they processed my retirement..."
"Not that. Last night... it was scary, wasn't it? A stranger suddenly taking your body, moving against your will."
"...!"
Haruna froze. Mom... knew everything. But she didn't seem to know it was an act. She believed Haruna had truly been possessed by the succubus.
"H-how did you...?"
"Mom has sharp ears... I heard all of 'Harona's' seductive voice. Look into birth control—pregnancy would be trouble. Good thing Dojin's so sweet..."
"Mom..."
Haruna's eyes welled up. Mom trusted her completely, without a shred of doubt about the act, even worrying about pregnancy. As tears fell, An Hyeonmi handed her tissues and gripped her hand tight.
"Tell me. What happened... what does that succubus want...?"
At her mother's warm, understanding voice, Haruna burst into the tears she'd held back. But she couldn't tell the truth.
"I don't know... I passed out drunk, and when I woke... I was in Dojin's room. My body wasn't mine. The succubus 'Harona'... took it and... Dojin... Dojin..."
She sobbed, unable to continue. An Hyeonmi hugged her daughter gently, patting her back.
"I see... that must have been so hard, my girl."
Mom's embrace was warm. Her frozen heart of guilt began to thaw.
"I... I tried to stop it. But my body wouldn't obey. The succubus... was too strong. And... and that feeling... it was so... so..."
"Good, right?"
An Hyeonmi whispered. Haruna flinched and looked up. Mom's eyes held deep, sad understanding.
"That's what's tormenting you most. It was horrific and terrifying, but your body felt pleasure. So you feel like a filthy, lewd person... that's the pain."
Haruna nodded fiercely. How did Mom know her heart so well?
"Mom... how...?"
Then Hadojin returned, and Harina came back from her call. Haruna swallowed her question.
...How does Mom know?
"What're you all doing? Thought you'd be done and cleared by now—waiting for me?"
"Just eating slow."
At Harina's question, Haruna picked up her spoon again. The air at the table had shifted subtly. Then Harina asked,
"Sis, now that you quit the company, what're you gonna do?"
Haruna snapped back to reality.
"Dunno... haven't thought about it. Wanna rest for a bit."
"Rest is fine, but you can't play forever."
An Hyeonmi spoke softly but firmly.
"Luna, help at Mom's shop for a while? Need someone for the books—perfect timing."
Her suggestion was practical, irrefutable. Haruna hesitated. Working at the flower shop meant more time with family—especially Dojin. Was that right? But she couldn't deny wanting to be near him.
"Yeah... okay, Mom."
An Hyeonmi smiled satisfied.
"Dojin's been helping a lot lately, so you two together will make Mom feel secure."
Harina's face hardened at that.
"What? Sis at the flower shop too? Then you'll be with Oppa all the time? I wanna work there too!"
Jealousy dripped from Harina's voice. Haruna recalled her own feelings from last night watching her sister.
In this vicious whirlpool of emotions, could they really be okay?
"What, you hate it? Me with Oppa?"
Haruna teased on purpose. Harina pouted.
"Not hate, but... Oppa has to work out with me—you can't hog him with work!"
"Look at her, already trying to monopolize Oppa."
As the sisters bickered, An Hyeonmi elegantly sipped her tea. Her gaze fixed solely on Hadojin at the center.
"Our Dojin's so popular—trouble. The women in this house might start a war."
At An Hyeonmi's joking words, Hadojin just gave a wry smile. He knew. This was no longer a joke.
The sweet, dangerous war of possessiveness and jealousy among the three women had already begun.
"Don't worry, ladies. As the only man in the house, I'll handle it all."
Hadojin said lowly. His voice carried the strong scent of an alpha male. Absolute confidence that he'd bear and control it all.
At his words, the three women felt their hearts race for different reasons. An Hyeonmi with the pleasure of submission to her master's decree, Haruna with relief at the knight's vow to save her, Harina with swelling trust in the strong one she'd follow.
"Thanks for the meal! Oppa'll do dishes, right? Gotta finish call with Yujeong!"
"Yeah."
Harina bolted to her room. Then, under the table, Hadojin's foot softly wrapped around An Hyeonmi's ankle. It slowly stroked up her calf. She trembled but showed no sign, spreading her legs wider to guide him.
When his toes reached her soaked core, she stifled a low moan while pretending to sip jjigae.
"Hngh...♥"
Haruna caught it—just a fleeting glimpse. The unmistakable female expression on Mom's face. As a female herself now, Haruna understood. Mom was in heat.
Why?? Why suddenly? Mom writhed, fighting the sexual pleasure, body twitching.
"M-Mom?"
Peeking under the table, Hadojin's foot was at Mom's pussy. Under her thin home skirt, wearing nothing, her secret garden was being toyed with by his toes.
"M-Mom? Do... Dojin?"
Haruna stared at them in shock, not grasping the situation.
"Mom. You're defenseless. Defenseless."
At Hadojin's loaded words, Haruna clamped her legs. She recalled what he'd said to her.
'A grown virgin that defenseless is trouble!' Now using it on Mom. Her own still-tender spot from last night throbbed hot.
An Hyeonmi didn't hide her pleasure-flushed face, sticking out her tongue to lick Hadojin's hand. Then, staring straight at Haruna, she spoke. Her voice was low and chilling, pulled from hell's depths.
"You asked how I knew you were possessed by the succubus? Because, my dear daughter... Mom's... been through it too."
"W-what...?"
"Like you, sometimes a succubus takes my body. Against my will... right now... I am..."
"Mom. Harina's in her room. Sis is right here—snap out of it. Don't lose to the succubus!"
Hadojin's shout left Haruna speechless. She'd vaguely sensed their relationship wasn't normal, but not like this.
"Then... Mom too... the succubus...?"
Haruna asked shakily. Shocked that Mom was truly victimized—unlike her own fake act.
An Hyeonmi nodded slowly. Tears glistened faintly in her eyes.
"Yes. I... was taken by that succubus too. And... sometimes, very rarely... it still takes my body."
