Not Just the Younger Sister, But the Older Sister Too (3)
In truth, Ji-yeon hadn't meant to tease Ji-eun's clit so many times before pushing inside.
The first time, she had simply pressed the head of her cock against those slick folds. The next few taps had been pure accident—Ji-eun's puffy lips clung so stickily to her that it felt good to keep doing it.
But when she finally tried to thrust in for real, her cock slipped upward instead, striking Ji-eun's clit with a wet smack.
“Nngh…!”
It was the same problem countless men faced on their first try. Even something as simple as penetration required a bit of technique.
“Ugh…”
Frustrated, Ji-yeon pulled back and tried again, only for her cock to slide off in the same direction.
Above her, the female let out a high-pitched whimper, but Ji-yeon barely registered it. All that mattered was getting inside.
“Shit…!”
Annoyed, she finally grabbed her own shaft, lined the head up with the twitching entrance, and shoved her hips forward.
This time it slipped downward.
“Ghh…!!”
The sensation that Ji-eun's hole was rejecting her sent a fresh wave of jealousy and anger surging through Ji-yeon's chest. Before she could turn that anger on Ji-eun, however, her little sister moved first.
Ji-ah yanked Ji-eun's head back and drove her own cock straight down her throat.
“Ughk!?”
“Aah… fuck…!”
Ji-ah panted in pleasure.
“This mouth-pussy is insane…!”
Ji-yeon watched Ji-ah's eyes melt with bliss and swallowed hard.
Does it really feel that good?
And then the bitter thought followed.
Then why the hell can't I do it?!
Why won't it go in? Why won't she take me? I want to feel good too! I want to use her hole too!
She raised her hand to slap the disobedient pussy, then froze.
Maybe…
The thought that her cock was simply too big flashed through her mind. Honestly, even Ji-yeon had to admit her own shaft was massive. Ji-ah's was a little smaller—maybe that was why it had worked so easily for her.
So what, then? I just can't do it?
She had to endure this maddening lust, yet she couldn't even get off with her cock? That wasn't fair.
“Ugh…!”
Lust, irritation, jealousy, and despair all mixed together until tears welled in Ji-yeon's eyes.
“Hic… hngh…”
Left with no other choice, she simply pressed the head of her cock firmly against Ji-eun's entrance. Even if it wouldn't go in, the sensation of the twitching hole kissing her tip still felt good.
Smack. Squelch.
Every time Ji-eun's pussy fluttered open, it brushed against the sensitive head. Just as Ji-yeon was about to resign herself to this much, an unexpected sensation raced up her shaft.
“Hng!?”
Suddenly, it felt as though her glans were being swallowed by hot, clinging clay.
W-what…!?
Ji-yeon's eyes flew open. Ji-eun's pussy was slowly—agonizingly slowly—spreading open around her. Like a mouth stretching wide to take something far too big, the entrance gradually parted, accepting Ji-yeon's cock with deliberate, certain motion.
And as it opened, inch by inch, her glans was being sucked inside that burning heat.
Just moments ago she had been desperate to shove it in, but now that it was actually happening—
“Hngh… hah…!!”
—all she could do was endure.
Ji-ah had been the same when she first thrust into Ji-eun's mouth: overwhelmed by the sudden rush of pleasure, able only to tremble and hold on. But their situations were different. Ji-ah had plunged in without thinking, so the pleasure had hit her all at once. Ji-yeon, however, was being swallowed with excruciating slowness.
Ji-eun's pussy took her glans deeper and deeper, each fraction of an inch sending fresh waves of pleasure through her. Ji-yeon wanted nothing more than to slam her hips forward, but she had already failed several times. If she rushed now and got pushed out again, she might actually cry.
So she endured.
“Aah… ah…”
The head sank in so slowly it was almost painful.
“Hngh… ah…!”
It felt like her nerves were being stroked one by one. Her patience was burning away, yet the reward finally came. The moment her glans fully entered, everything slid forward in one smooth motion.
“Hnnngh…!!”
Ji-yeon's body shuddered. An enormous wave of pleasure crashed over her all at once.
What… what is this…!?
It felt incredible. So good it should have been illegal, like a drug. The tight, scorching heat wrapped around her entire length. The countless soft folds inside stroked and massaged her from every angle, moving on their own even when she stayed still—an automatic cum-milking machine.
For Ji-yeon, already driven to the brink, it was too much.
Ah—
Something was rushing up inside her. A ringing filled her ears. Heat raced from the back of her neck straight to her brain, so intense it almost felt cold. Instinct took over. Before the climax could hit, she yanked her hips back and slammed forward with everything she had.
The pleasure exploded at the same instant. It felt like she was being launched upward, like every last drop of desire was being sucked out from the deepest part of her cock.
“Aah… hngh…!!”
Ji-yeon barely managed to stifle the moan that tried to escape. Thick, hot, sticky cum erupted from her in heavy pulses, painting Ji-eun's insides white.
“Aah…”
Ji-ah's first orgasm had lasted a long time, and Ji-yeon's was no different. It was the first time in her life she had experienced the pleasure of ejaculating—the peak that only those with a cock could know. Even so, it eventually ended.
“Haa…”
Ji-yeon exhaled shakily, already missing the sensation. She wanted to feel it again. So she began moving her hips once more, slow and careful at first.
“Feels… good…”
Just like Ji-ah, Ji-yeon showed no signs of post-nut clarity. Her lust had eased only slightly. Her cock remained rock-hard, her desire still burning hot. There was no way she was pulling out after just one orgasm—not when she had only just managed to get inside this lewd hole.
Her shaft stirred through the cum-filled pussy, pulling back before driving forward again. Each thrust grew more confident. She found her rhythm, adjusted her stance, and lifted Ji-eun's legs over her shoulders to deepen the angle.
“Hngh… ah…!”
Her strokes grew longer, harder. She was fucking the female exactly how she wanted. A satisfied smile spread across Ji-yeon's face.
See? It wasn't that hard.
She had thought Ji-eun's pussy was rejecting her, but it had just been her own lack of experience. Now that she knew what she was doing, there was no need to hesitate anymore.
Thud! Thud!
Her thrusts grew deeper and more powerful. She chased her own pleasure without restraint, hips snapping forward again and again.
“Aah… hah…!!”
Ji-yeon's breathing grew ragged. Even staying still inside this pussy felt incredible, but pounding it at her favorite angle and pace was driving her insane. Every thrust threatened to melt her mind completely.
Then—
“Hngh!?”
Ji-yeon froze mid-thrust. Ji-eun's pussy had suddenly begun to spasm around her, clenching and rippling far more intensely than before. The already incredible hole was now convulsing like a living creature in heat, squeezing and milking her with desperate, sticky contractions.
“Hah… hngh!?”
Only then did Ji-yeon realize what was happening. Ji-eun was climaxing—because of her cock.
“You…!”
The words that burst from Ji-yeon's lips were something no one who knew her would ever expect to hear.
“You fucking bitch!!”
The fact that the female she thought she had already dominated was still managing to surprise her filled Ji-yeon with irrational anger—and shame. It felt like she was the one being toyed with.
She raised her hand and brought it down hard on Ji-eun's heavy breasts, which had been bouncing with every thrust.
“I told you to stay still!!”
“—!!?!?”
Ji-eun's silent scream was muffled by the cock still buried in her throat. The sudden slap made her pussy clamp down violently around Ji-yeon.
“Aah, shit…!!”
Ji-ah shuddered as well, the unexpected tightening catching her off guard.
“Aish, unnie!”
“S-sorry.”
It was the first time the sisters had spoken since they started using Ji-eun's holes. But there was no time for sisterly bonding. Ji-eun's pussy was already convulsing again, dragging both of them toward another climax.
“Hngh…!”
Ji-yeon's breathing grew harsh. The familiar pressure was building at the base of her cock once more. At the same time, Ji-ah felt her own second orgasm approaching.
Their hips moved with renewed urgency, pounding into Ji-eun's holes with everything they had. They no longer cared about each other—only the hot, clenching flesh wrapped around their cocks mattered.
“Aah… aah…!!”
“Haa… ah…!!”
Both sisters came at once, pumping another thick load of cum deep inside Ji-eun. It wasn't as much as the first time, but it was still more than enough to leave them gasping.
“Haa…”
“Huu… huu…”
Their eyes met. Ji-ah looked completely blissed out, and Ji-yeon knew she probably looked the same. The realization made them both feel strangely embarrassed.
They had just filled the same girl with two loads each, yet seeing each other like this felt oddly intimate. A sudden awkwardness settled between them.
Meanwhile, the female between them—still stuffed from both ends—began to tremble and convulse once more, cumming hard around the cocks that had just finished inside her.
“Kuh…!”
“Aah!?”
The scent of cum and pussy juice filled the entire living room. A thin trickle of red—proof that Ji-yeon's cock had torn Ji-eun's hymen—mixed with the white fluids and dripped onto the floor.
