EP.76 In Bed with My Sister 

In the pitch darkness, only the faint moonlight seeping through the window and the sound of crickets broke the heavy silence in the room. 

Akari hugged the small, trembling body in her arms even tighter. 

Just a moment ago, Yuu had knocked on her door, nearly in tears, saying he’d had a scary dream. 

In the end, she brought her little brother into her bed and only after a long time of comforting him did his trembling finally subside. 

“Are you… feeling a little better now, Yuu?” 

“Yeah. A little… I feel better now, thank you, sis.” 

Hearing his still-childish voice, Akari couldn’t help but let out a small laugh. 

“Really, coming to your sister’s room and begging to sleep together just because of a nightmare. Are you a little kid or what?” 

Then, suddenly reminded that Yuu really had become a child again, Akari sighed softly and continued. 

“So… you dreamed I was leaving? Do you remember it in detail? What kind of dream was it?” 

Her question wasn’t just simple curiosity-she was hoping for a clue to this strange phenomenon. 

Yuu buried his face deeper into Akari’s soft chest and mumbled, 

“It was a much younger you… but you suddenly became big… and you were about to leave home. I was crying, begging you not to go, to stay with me, but you didn’t look back even once and just left…” 

“A big sister…?” 

“Yeah. Just like you are now… wearing pretty clothes, with makeup on…” 

Akari froze at his answer. 

There was no clear evidence, but she was sure it was a memory from when she left for university in Tokyo, around age twenty-a distant past that the current child Yuu could never have known. 

So then… 

“No way… Yuu, do you remember…?” 

“It was just a dream… I don’t remember much else, sis. I just… I was so sad and scared you’d leave me alone…” 

Of course, for Hyunseong, it was all a calculated act to dig deeper into Akari’s heart. 

But to Akari, Yuu’s words meant something completely different. 

‘Could it be… just like Fumika said, as I fulfill Yuu’s desires… little by little, his lost memories are coming back?’ 

Thinking that, the guilt and confusion that had been clouding her mind seemed to lift like fog. 

Maybe this forbidden act really was the only way to bring Yuu back to normal. 

That dangerous hope began to grow uncontrollably inside her. 

“Sis… why did you leave back then? Did you hate living with me, Mom, and Dad?” 

Yuu looked up at her with teary eyes, and Akari was at a loss for words. 

“That’s…” 

She couldn’t tell the real reason. 

Even if he was her little brother again. 

No, she couldn’t tell anyone. 

That she’d left because she realized her feelings for her stepbrother weren’t just sibling affection. 

That she’d run away to punish herself for those forbidden feelings. 

That she’d started dating Daiki-his complete opposite-just to forget Yuu. 

“It’s just… I wanted to do a lot of things as an adult. Rather than living the same days in this small country town, I wanted to go to the big city and have new experiences.” 

As if all her problems would be solved in the city. 

As if a sparkling future was waiting for her there. It wasn’t a lie, but it wasn’t the whole truth either. 

“New… experiences?” 

“Yeah. When you grow up, you’ll understand how I felt, Yuu.” 

As she said it, Akari suddenly wondered about Yuu’s own feelings. 

When he’d reached adulthood, he’d become completely listless, as if he’d given up on everything. 

He’d been so bright and lively as a child. 

‘I’ve never actually asked him, have I?’ 

Lost in thought, Akari gently stroked Yuu’s small head. 

Then, unexpectedly, Yuu asked, 

“Then, sis… are you happy now?” 

“Huh?” 

The innocent question pierced straight through Akari’s heart like a sharp blade. 

Happy? 

Happy? Am I happy now? 

Her relationship with Daiki was falling apart. 

Her unwanted secrets were piling up. 

Her heart was in turmoil every day-had life in the city brought her the “happiness” she’d dreamed of? 

Akari couldn’t answer. 

She felt like she was finally facing her own neglected, pitiful truth. 

As if reading her mind, Yuu whispered in a small but clear voice, as if seeping into her ear and the deepest part of her heart, 

“I… I could make you happier, sis.” 

It was a determined, almost provocative voice, unbelievable coming from a child. 

‘Is he… jealous?’ 

Thinking that, Akari couldn’t help but laugh. 

At the same time, her heart began pounding wildly. 

“Pfft… Where did you learn to say things like that? You’re ten years too early to say that to your sister, you brat.” 

But thanks to that, the suffocating, heavy air in the room lightened just a bit. 

Had he said it on purpose? 

The thought crossed her mind, but she shook her head. 

There’s no way a ten-year-old could think that far ahead. 

It must just be childish imitation of adults. 

Still, his words kept echoing in her ears. 

Just then, something hard pressed against her lower belly from between Yuu’s thighs, just like at the river earlier. 

“…!” 

Akari instinctively held her breath. That familiar sensation, that unforgettable heat. 

“Y-Yuu… you, again…!” 

She looked down at Yuu in disbelief. 

Yuu hung his head, his shoulders trembling. 

“S-sorry, sis… Even though you helped me so much today, it happened again… I really don’t know why…” 

Instead of getting angry, Akari let out a helpless laugh. 

In that laugh was a kind of resignation-and a bit of anticipation she couldn’t deny. 

Watching the bulge in his pajamas, Akari unconsciously bit her lower lip. 

“Haa… You really… I can’t handle you.” 

She gently patted Yuu’s small back as she muttered. 

The wall of resistance deep in her heart had already crumbled. 

Fumika’s advice. 

The fragments of “memory” Yuu had shown. 

And the desperate, burning signals this small body kept sending her. 

Everything was leading her in one direction. 

‘Fine, if it’s come to this…’ 

Slowly, very slowly, she slid her hesitant hand under Yuu’s thin pajama top. 

The warmth and smoothness of his bare skin sent a shiver down her spine. 

Yuu flinched, his breath catching audibly in the darkness. 

“Sis?” 

“…Stay still.” 

In a low voice, Akari climbed on top of Yuu. 

Then, without hesitation, she pressed her lips to his as he tried to speak. 

“Smooch♥ Churup♥ Mmm…♥” 

What started as a hesitant, gentle kiss quickly turned into a heated exploration. 

Akari, as if deciding not to think about anything else, sucked and licked Yuu’s small lips with abandon. 

The sweet breath and feel of his tongue mercilessly snapped the last thread of her reason. 

‘This is all to turn my brother back to normal… So…’ 

Repeating that excuse to herself, Akari slid her hand into Yuu’s pajama pants. 

She grasped the thing she’d touched so many times before, but which still surprised her every time. 

It was even harder and more swollen than at the river, throbbing as if it had been waiting for her touch. 

“Hngh… Sis…” 

Panting between kisses, Yuu-no, Hyunseong-silently clenched his fist in triumph. 

Akari’s confusion, her self-justification. 

Her finally unleashed, pent-up desire. 

He had waited, with the face of an innocent child, for her to break on her own. 

And that moment had finally come. 

“Yuu… It’s okay… It’ll be okay…” 

Murmuring comfort to no one in particular, Akari pulled down Yuu’s pajama pants and, without hesitation, roughly pulled down her own underwear. 

“Whew. Whew.” 

After a few deep breaths, 

Akari climbed on top of Yuu, and with trembling hands, guided his stiff erection to her most intimate place. 

The moment the tip touched her sensitive flesh, a jolt of electricity and uncontrollable excitement surged through her. 

“Hngh…!” 

She knew she could never go back after this, but she was too far gone to stop now. 

Thrust♥ 

“Hngh♥” 

As the foreign sensation and shivering friction pierced her body, Akari stifled a short scream. 

At the same time, a wave of overwhelming pleasure and guilt crashed over her as she finally opened the forbidden door. 

Even as her mind went white with ecstasy, Akari realized one thing: 

There was no going back to the way things were. 

“Churup♥ Chururup♥” 

Thrust♥ Thrust♥ Thrust♥ Thrust♥ 

She kissed Yuu’s lips again, moving her hips instinctively.
