The Sister Who Wants to Tag Along

I was held in Yang Dahee’s arms. She was the older sister who reserved her affection only for me. The sister who reserved her body only for me. She was the sister who held only me.

‘My sister’s chest… it’s so soft….’

It felt like a cushion, pressing against the tip of my nose and sinking in deep. I buried my face into her ample bosom and wrapped my arms tightly around Yang Dahee’s waist.

“Nng….”

Unlike her previously furrowed expression, Yang Dahee let out a sultry moan. Her breath tickled my ear. Blood began to rush to my groin.

“Huu….”

I let out a long, shaky breath, trying to hold it back.

‘Huu, no. The person I’m with is my “sister.”’

I wrapped my arms deeper around her slender waist. I hugged her tightly, bracing my body and trying to hold firm. My nose tip touched a deep, hidden spot—a place where a little sweat had gathered, like a deep valley. It was the cleavage between her breasts.

“Hng….”

Because a moan—I couldn't even tell whose it was—escaped at the same time, I managed to hide the fact that I had just taken a sharp, ragged breath. The scent of my “sister’s” skin was exceptionally rich…. I was fully aroused.

‘Haa, that was a close one.’

If I hadn’t pulled my hips back, she would have noticed.

‘No. This is immoral.’

She was someone I shouldn't look at as a woman. I tried desperately to drain the strength from my erection. I tried to recall the feelings of a younger brother who loved his sister. I filled my ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠mind with the memories of just the two of us.

‘Sister, I love you….’

The corners of my mouth curled up. Yang Dahee’s expression, which had been on the verge of sagging when she first hugged me, softened. I wanted to cheer her up. I wanted to see that specific smile she only showed to me. I buried my face into her again.

“Ugh, Sister.”

I rubbed my face against her large breasts. A younger brother who snuggled into her on his own. I acted as cute as I could and slowly lifted my head.

Yang Dahee frowned. It was the scent coming from her younger brother, who had just returned from wandering outside. It was the scent of another woman.

‘Yurim and… Yeryeong?’

A familiar scent, and one that was still strange. It was stronger than usual. The scent of outside women pricking at her nose made the corners of her mouth drop.

“Sister?”

I was acting cute, rubbing my face against her breasts. Yang Dahee took a step back and looked at her younger brother. She stared at the face that resembled her own. She thought, meeting eyes that shouldn't know about women yet.

‘Dajun, are you trying to get close to Yeryeong now, too?’

The scent of women, which she hadn't smelled before, was particularly strong. It was as if the boy who had only ever hung out with his childhood friend had started mingling with other women.

“Haa….”

Why did she feel so stifled? They were probably just hanging out. Yang Dahee, feeling as if a part of her heart was ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠blocked, spoke in a voice so stiff it surprised even herself.

“What have you been doing?”

“The department store.”

He didn't avoid her gaze, but it wavered slightly. Yang Dahee stared at him with eyes that wouldn't miss a single thing and said,

“Why there? Did you need something?”

“No. To buy something for Yeryeong.”

He added something he hadn't even been asked. “Yurim took me. She said we should go together.”

“Then what’s that in your hand?”

Something she had been bothered by since earlier. Yang Dahee just stared at him silently, her eyes narrowed.

“Ah….”

His lips trembled, as if he had expected this to happen. Yang Dajun, looking hesitant, held out both hands. It was a shopping bag containing something.

“Did you buy it?”

“It’s a gift.”

He shook his head as he answered, a thousand thoughts racing through his mind. Yang Dahee glanced inside the shopping bag and asked,

“⋯What is it?”

“Clothes. I said it was fine, but they kept insisting on buying them for me.”

Only then did he lift the bag to show her the contents. Even at a glance, the brand looked expensive. He had been gifted clothes by the two sisters who were his childhood friends. Yang Dahee watched her brother lower his arms and said,

“Must be nice. Wear them well.”

“Yeah, they’re expensive. It’s a bit burdensome, but I can’t help it.”

“…”

Yang Dahee bit her lip without realizing it. It seemed Yang Dajun had misunderstood her words. She had meant that since it was a gift, he should wear it well….

‘Don’t tell me Dajun was worried about our family’s situation? Even while pretending like everything was fine?’

She felt sorry as a sister. She had raised him without parents, but she was a very lacking “step-sister.” Her mouth tasted bitter.

“Sister? What’s wrong?”

“…It’s nothing.”

Because it wasn't something she could tell him. The poor environment and the thick scent of women starting to come from her brother. It felt as if he were drifting away from her.

‘Dajun wouldn’t do that, but….’

Yang Dahee recalled last night. Her brother, who had come home covered in the scent of women. While he was sleeping, she had checked “that place.” She had even cleaned it for him. It was her way of protecting him as a sister so that other women couldn't snatch him away.

‘I want to make it even more certain….’

Yang Dahee blew away her worries and filled her heart with thoughts of her brother. ‘I want to do it again tonight….’ He was usually a quiet brother. Since he had been running around outside, he wouldn't be able to overcome his sleepiness. He would fall fast asleep at night, so she would have to take care of him as his sister.

“Sister, what’s wrong?”

She had hugged him without realizing it. Unlike her, he had a small body, so he fit right into her arms. If only he would stay with her like this forever. Their parents were gone, and now there were only the siblings. Even if they were only half-siblings, they shared the same blood. She didn't want to be apart from Yang Dajun.

‘Dajun, I’ll live for you….’

Yang Dahee tightened her grip. While hugging Yang Dajun, she squeezed his back muscles. She patted his back in response to his voice calling her.

“Sister, I love you.”

“Yeah, me too.”

Their hearts were in sync. Their heartbeats matched. Yang Dahee looked down at the floor and said,

“Dajun, I have something for you.”

It was a size and shape that only lovers would exchange. It was a large chocolate bar.

“Are you giving this to me?”

“I bought it on my way here. Hehehe.”

That wasn't actually true. She hadn't bought it on her way home from work; she had left work specifically to buy it for him.

‘Because I love Dajun that much.’

Yang Dahee gave the chocolate to her brother with a smile. “Here, take it.”

“It’s heart-shaped.”

His expression brightened. Yang Dahee emphasized one word in particular.

“Yeah, they say it’s what people give to their boyfriends a lot.”

“Hehehe, then other couples must be disappointed.”

“…Why?”

Her voice trembled. The word “couple” bothered her. But Yang Dajun continued to speak while hugging the chocolate, smiling.

“Because you bought this, Sister. They must be sad they couldn’t buy it.”

That’s right. Yang Dahee nodded. She wore a fake smile. Boyfriend, couple. While her brother was carefully happy thinking about others, she had been thinking about something else entirely.

“Yeah, that’s right….”

Yang Dahee repeated it in a deflated voice and slowly looked to the side. A small chocolate bar placed on one side. She saw her younger sister in front of it.

‘Dami, she must have been tired.’

She was asleep even though Yang Dajun had arrived. Her hair was disheveled.

“Dami.”

“Huum….”

“Dami?”

“Umm…?”

She opened her eyes cautiously. Her eyelashes fluttered. She moved her lips, mumbling, and then her expression changed abruptly.

“What.”

Yang Dami glared like a cat hissing. Then, seeing her older sister in front of her, she softened. “…It’s you, Sister.”

“Hehehe.”

“Why did you wake me up?”

Yang Dahee looked to the side. “Dajun is here.”

“Ah.”

She whipped her head away. The wind blowing coldly suggested what was about to happen. ‘Dami, she’s going to get angry again, right?’ It was obvious. Yang Dahee smiled at her two younger siblings. But then.

“Ah….”

The first sound that came out of Yang Dami’s mouth wasn't a word. She just stared at Yang Dajun, letting out a moan. ‘Why is she like that?’ Then, her eyelashes trembled.

“Y-you’re here?”

“Yeah….”

Yang Dajun also seemed awkward. Though small, her characteristic sharp voice remained.

“H-hey… aren’t you cold…!?”

“I was fine when I came home.”

He was the older brother, but his voice was shrinking. On top of that, his younger sister went a step further. ‘Dami, what are you doing by yourself?’ She was stroking herself. Alternating between her hair and her cheeks. It was while Yang Dajun was scratching his head and avoiding her gaze.

‘Why is she like that….’

Yang Dami muttered, fidgeting with her hands. “Anyway, wear your clothes properly….” She headed to the bathroom, leaving Yang Dajun, who was tilting his head, behind. She kept babbling until just before she closed the door.

“Ugh.”

Looking to the side, Yang Dajun looked embarrassed. He forced a smile with only one cheek lifted. An older brother who was afraid of his younger sister…. She, the “sister,” would just have to take care of him. ‘Hehehe, he’ll think it’s only his sister, right?’ He must be hungry since he’d been out and about. Yang Dahee was about to move, thinking of making him a meal.

“Sister, are you going to make dinner? Then I’ll go to the mart.”

“Why are you doing the grocery shopping?”

She asked, blinking her eyes.

“You just came back from work, Sister. I wanted to make something for you.”

“I told you, you don’t have to do that.”

She stroked his hair. He seemed to want to help her somehow. Unlike usual, he was being stubborn.

“I don’t know, I’m going.”

“It’ll be hard.”

“It’s my heart thinking of you, Sister….”

He said, looking at the chocolate. Such a gift was trivial compared to his true heart, but he was so innocent. The problem was that “heart thinking of his sister” sounded like something else entirely.

‘Hehehe.’

A boy who cooks for a woman. A boy who only thinks of her. Yang Dahee bit her quivering lips slightly. She calmed her breathing and said,

“Haa… then let’s go together.”

“You too, Sister? Just rest.”

“It’s better to go together since we’re going.”

She said it lightly, pretending she had no other intentions. “Shall we go out with your sister for the first time in a while?”

“Yeah, I’d love that.”

Yang Dajun smiled brightly. He nodded, not knowing her true intentions. ‘Dajun, I’m sorry….’ Because she was filled with the thought of exhausting her younger brother. She had to drain his energy so he would fall fast asleep at night. Only then could she treat him well as his “sister.”

Yang Dahee mapped out the route to the mart in her head. Yang Dami walked out of the bathroom.

“What, where are you going?”

“To the mart. Dami, you’re not going, right?”

“Yeah. I’m going out to play.”

It was the same answer as usual. She was a child who preferred to stay outside. Instead, Yang Dahee looked to the side and said,

“Okay. Dajun, let’s go just the two of us.”

“Yeah, Sister.”

She gestured with her chin and was about to change her clothes. That was when.

“Wait a second.”

Yang Dami had cut in. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠She had just poked her head out while rummaging through her bag. Yang Dami rounded her lips and asked in a sharp voice,

“Sister, weren’t you going alone? Is he going too? Just the two of you?”

“Yeah, Dajun said he wanted to go grocery shopping. He said it’s fine if we go together?”

“Ah….”

She just let out a moan. Yang Dami stood there blankly, looking back and forth between the two.

‘Oh my.’

I flinched and turned my head slightly. I had no choice but to look away. It was only natural, as a grown woman had just thrown off her clothes, revealing her naked body.

“What’s wrong?”

She didn’t even tilt her head anymore. She just glared at me and picked up other clothes to wear. ‘Does she think it’s fine just because I’m her brother?’ She jiggled her large breasts in front of me. She put on leggings and revealed her plump mound without hesitation.

“Hng….”

Feeling my jaw tremble, I opened my mouth reluctantly.

“Sister, turn around and change….”

“Hmm?”

Yang Dahee bounced her hips and didn't think much of it. “What’s the big deal about that? Hehehe.”

“Haa….”

She wouldn't understand even if I told her. I decided to give up. As long as she didn't do that in front of other men. ‘Not that my sister would ever do that.’ I didn't like the idea of her dating someone else.

‘…?’

I felt something strange. I didn't know why I hated it. Lee Yeryeong had said something earlier.

[Hng, Oppa. Please pay more attention to women from now on.]

She must have been talking about Lee Yurim. Then this had nothing to do with Yang Dahee. ‘Or am I just wary of outside men because she’s my only sister? Like a sister-in-law and a sister-in-law?’ While I was narrowing my eyes and pondering, Yang Dahee called out to me.

“Let’s go, Dajun.”

“Ah… yeah.”

I pretended not to have any thoughts. I acted out the usual “Yang Dajun.” The sister I truly love, the sister who makes my penis stand tall….

‘…?’

I tilted my head and took a step. I was about to follow her to the entrance when.

“W-wait a second!”

I heard a crashing sound from far away. Someone shouted as if the house were about to collapse and ran out.

“Hey, Yang Dajun! I’m going too!”

Her short ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hair fluttered. She came running, then unfolded the clothes she was holding in her hand. Then she threw off her clothes and said,

“Yang Dajun, wait! I’ll be dressed in a second!”

Standing right in front of me was my younger sister, Yang Dami.
