Chapter 140: Side Story - Younger Sister (23) ♥
Chapter 140: Side Story - Younger Sister (23) ♥
Shin Ye-ji’s world shrank to a single point in an instant.
Hee-ik. Her breath hitched, trapped in her throat. Even though he was entering her slowly, the movement felt impossibly fast.
She wondered if he was being too hasty, too merciless.
Contrary to Ye-ji’s fears, however, Kang Yu-jin was already moving with extreme deliberation.
Even as he felt like he might lose his mind from the sheer arousal, he pushed inside slowly.
A long time ago, when he’d first slept with his younger sister, he had almost ruined everything by rushing. If his sister hadn't harbored feelings for him back then, their relationship would have ended right there.
Knowing this all too well, Yu-jin moved with intentional slowness.
He could clearly feel his glans stretching the pussy hole, parting what must have been the hymen. Perhaps it was because Shin Ye-ji had never even properly masturbated in her life, but Yu-jin felt a powerful resistance as he gradually buried his cock inside her.
It was hot, as if he were melting, yet he could feel her body simultaneously failing to accept his cock and trying to push it out in real-time.
Yu-jin panted, out of breath, and as he continued to push himself in, his eyes met his sister’s, who was still locked in an embrace with Ye-ji.
The expression on his sister’s face...
It was incredibly complex. It wasn't exactly good, nor was it entirely bad. If he had to put a name to it, it was something close to displeasure.
It was the look of someone feeling deeply uncomfortable with the fact that she had to share the brother she cherished and loved, even if it was out of necessity.
And yet, seeing her accept it as inevitable was quite a sight. The way she set her own emotions aside because she knew this was necessary.
Of course, from Yu-jin’s perspective, this threesome wasn't bad at all, but if he put himself in her shoes, it wasn't hard to understand his sister’s thoughts.
If the positions were reversed, and a friend of Yu-jin’s suggested polyamory under the guise of a fake marriage, leading to the three of them doing this...
‘I’d probably want to kill him.’
Through this sudden moment of introspection, Yu-jin understood his sister’s feelings. Even so, he continued the act.
It was a bit late to stop now just because he’d had second thoughts. More importantly, his sister had already decided to accept this; it would be wrong to kick away her consideration now. It would be like flipping over a table that had already been set.
So, Yu-jin silently pushed his cock forward, pressing his body tight against Ye-ji’s as he heard her voice rise in something close to a scream.
Her small but firm buttocks pressed against him. He shuddered at the soft sensation against his pelvis, but noticing his sister’s longing gaze, he leaned down and kissed her.
Instead of thrusting his tongue in the moment their lips met, he kissed her with deep affection. He tilted his head, tangled their tongues, and stroked her cheek while gasping for air. Yu-jin felt a surge of excitement at the fact that he was performing this familiar act with Shin Ye-ji sandwiched between them.
The realization that this might become a part of his daily life filled his mind.
That wasn't all. Yu-jin thought to himself as he felt Shin Ye-ji’s virgin pussy take his cock all the way to the hilt, twitching and tightening around him.
‘...She’s incredibly tight.’
Virgin pussies were always like that, but perhaps because she was such a pure girl who looked like she’d never even touched herself, the pussy’s grip was a match for her innocence.
It was so tight it felt like it might snap his cock off, yet the inside was so sensitive that she reacted explosively to even the slightest twitch, her hips jerking reflexively.
Yu-jin stayed still, kissing his sister and waiting for Ye-ji to adjust.
He felt like he might explode at any second, but he forced himself to endure, parting his lips.
His sister’s tongue slid in as if she’d been waiting. Between the wet, splashing sounds and Ye-ji’s sobbing whimpers, the heavy panting of his sister and himself harmonized.
Huddled together in one side of the bathtub that was barely large enough for one person to lie in, Yu-jin spoke as the kiss ended.
“I’m going to move.”
Kang Yu-ri’s eyes flickered as if she were hesitating, but then she nodded.
Immediately, a high-pitched moan erupted. Though startled by the piercing sound, Yu-jin deliberately stimulated the vaginal walls with slow, leisurely movements.
The sensation was quite different from Kang Yu-ri’s.
It didn't feel like she was just clamping down on his cock; it felt like she was trying to crush it into necrosis. Unlike someone who only knew how to tighten the entrance because they weren't used to it, her interior felt somewhat more spacious.
It was narrow simply because it had never been used, but it felt as though there was no conscious control over the tightening itself. Yu-jin groaned at the distinct sensation, navigating Shin Ye-ji’s pussy with slow strokes.
He felt the pussy meat squeezing him tight, and just as his glans rubbed against her cervix—which was firm and unyielding from never having been stimulated—Yu-ri spoke.
“Oppa.”
“Uh, yeah? Yes.”
“You look like you’re enjoying yourself.”
“Well, it does feel good...”
He couldn't exactly lie and say it didn't while Ye-ji was listening. No matter how naive and kind the girl was.
It wasn't right to speak ill of someone who would be with them from now on, especially not while she was right there.
Though Kang Yu-ri seemed dissatisfied even with that.
“Better than with me?”
“Hey, what are you... what kind of question is that?”
“Does Ye-ji’s pussy feel better than mine? Are you two more compatible?”
Her blunt words were strangely venomous yet pitiful. He got the strong impression that she wasn't revealing her true feelings.
Yu-jin could immediately see through his sister’s heart.
It wasn't that she wasn't jealous of Shin Ye-ji, but it was more than that.
She was clearly regretting whether there might have been a normal path in life for the brother she loved.
The road not taken, the kind of ending her brother might have faced if not for her love.
She was clearly agonizing over that.
Knowing his sister’s inner thoughts, Yu-jin maintained a slow pace as he fucked Ye-ji’s pussy, leaning down to press his lips against his sister’s.
When he kissed Kang Yu-ri’s cheek as she tried to turn her head away, and moved his lips across her skin as if drawing a line to find her mouth, she let out a faint, helpless giggle and met his lips again.
That was their second kiss. In the short span of time, he performed this second act of affection, holding both of Ye-ji’s wrists as he thrust. Instead of tangling tongues, he simply brushed his lips against hers with love, and his sister’s hand slowly moved to stroke the back of Yu-jin’s hand.
Following his sister’s lead as she guided his hands from Ye-ji’s wrists, his hands eventually came to rest on his sister’s waist via her thighs. The younger sister who was jealous, who didn't mind ruining herself for her love, but who wanted to spare her brother from a desperate end.
And yet, the youngest sister—and lover—who simultaneously wished for her brother to willingly walk that path of ruin with her.
Understanding her complex heart, Yu-jin gripped his sister’s waist with both hands, and Kang Yu-ri hugged Ye-ji as if responding to him.
Ye-ji’s moans, which had sounded like weeping, began to tremble thinly.
“It looks like she’s finally getting used to it.”
Yu-ri’s voice, flowing out alluringly, meant she had completely regained her composure—or at least, that she would overlook this minor transgression for now.
Yu-jin smiled slightly at his sister’s mercy and leniency.
“Then... shall we start moving for real?”
Accompanied by Ye-ji’s moan of confused distortion, Yu-jin pulled his waist all the way back while keeping his arms wrapped around Yu-ri’s waist, as if he were doing it with her right then and there.
Ye-ji, who hadn't even been able to speak—only let out groans due to the foreign sensation, the awkwardness, the intense pleasure, and the underlying pain—seemed to regain her senses and slowly lifted her head.
“Yu-ri-ya—”
She locked eyes with her friend and tried to say something, but her eyes snapped wide and her mouth fell open.
The sensation of her pussy being filled again—after feeling a sense of regret, emptiness, and even loss when his cock had pulled out—was different this time. It wasn't slow. Her reason vanished under the sheer force of the impact, which came fast and violent. Pleasure flooded in, bleaching her mind white.
Her vaginal walls, sensitized by the long session of foreplay, masturbation, and stimulation, surrendered to the cock digging into her, tightening around its entire length. Kang Yu-ri smiled as she watched her friend panting.
“Oppa’s cock feels amazing, right? From now on, hands or dildos won't be enough for you.”
Ye-ji’s mouth bobbed, unable to say a word, too busy exhaling every breath that entered her lungs. She couldn't even answer. She just gasped with a face contorted by pleasure, tears streaming down as she gritted her teeth.
Naturally, Yu-ri’s face drew closer.
Their lips met. A kiss that friends shouldn't share. It was as if she had conceded the first kiss but wouldn't give up the second; she forced Ye-ji’s lips open with her own and pushed her tongue inside.
Yu-ri’s tongue tangled with the smaller one. Skillfully leading the tongue to make Ye-ji suck on hers and drink her saliva, Yu-ri searched for the erogenous zones inside her friend’s mouth.
A heavily distorted moan scraped through Ye-ji’s throat. Ah, her voice is going to be completely hoarse tomorrow, Yu-ri thought, but she didn't stop, continuing to stimulate her.
At that moment, Kang Yu-jin also found the weak point where Ye-ji’s pussy felt the most. As his foreskin scraped firmly against her sweet spot, Ye-ji’s waist shook convulsively, and her legs gave out, her knees hitting the floor of the tub.
Thud!
The sound made the siblings stop in surprise. As Yu-ri’s eyes widened and Yu-jin froze mid-thrust.
Shin Ye-ji, feeling a sense of loss as if an organ had gone missing the moment his cock slipped out, slumped down. Spilling saliva, tears, and pussy juice, she reached her climax.
It was a primal sound. A moan that made one wonder if her usually cute voice could even sound like that.
When the moaning stopped, Shin Ye-ji collapsed into Yu-ri’s arms.
Her body trembled, exhausted, while in contrast, Yu-jin’s cock was still throbbing, pleading for more. Yu-ri looked at her brother’s cock as if she had no choice and said:
“Oppa.”
“Yeah?”
“Pick Ye-ji up. It’ll be better to continue on the bed.”
The bathtub wasn't that safe. Just hitting her knees now looked like it would leave a bruise; there was no saying that the next fall wouldn't be more dangerous.
Yu-jin easily accepted the suggestion and skillfully scooped Ye-ji up in his arms.
The problem was the position.
“...Oppa.”
“Might as well.”
“Seriously, what are you even saying?”
She grumbled but didn't refuse. Ye-ji didn't have the strength to refuse, and even if she’d had the mind to, it would have vanished now.
The girl who had been a virgin until moments ago widened her eyes at the foreign sensation digging back into her. She twisted her head and poured out a moan, and as her limbs were held tight so she couldn't even struggle, she felt his cock push all the way to just below her uterus. She burst into tears and hit her climax once again.
Pshhh! A fountain of fluid erupted. Kang Yu-ri laughed as she was suddenly hit in the face by the spray.
“Is this revenge? Honestly, Ye-ji, you’re so childish.”
She joked as she pinched Ye-ji’s clitoris. Her legs shook uncontrollably, and the siblings headed toward the bed, teasing Ye-ji sexually as if to show off.
They didn't wipe their bodies. The sheets would have to be washed after today anyway, and they kept several spares since this sort of thing happened often.
As soon as Yu-ri, Ye-ji, and Kang Yu-jin reached the bed, they continued the act as if they’d been waiting.
As Yu-jin climbed on top of the collapsed Ye-ji, and Yu-ri lay on her side next to them watching her brother work, Ye-ji thought with what little reason she had left.

That she would have to skip her classes tomorrow.
