Checking on My Sister’s Man and Getting Wrecked

“...Alright. Keep going.”

As soon as those words left her lips, Tae-seok gripped her hand a little tighter.

A warm energy began to seep in from his fingertips, spreading through her like a gentle current.

Nothing was visible to the naked eye, yet he could clearly feel something flowing into her.

…It’s reacting. This… is going to be a challenge for me too.

Tae-seok muttered to himself.

Ever since the status window appeared and he gained these unknown powers, he had made Eun-jung his woman. But that was only a single case.

It might not have been because of his ability at all.

He had always wondered whether it was her lingering affection for him, or the guilt from her relationship with his father, that had led her to surrender her body.

But Eun-su was different.

She was a woman he had never interacted with before — someone he was truly seeing for the first time.

She was strong, fierce, suspicious, and overflowing with confidence.

If his power worked on a woman like her, then he could finally be certain of his strength.

He studied her face up close.

Even as she felt his energy, she was clearly trying to resist it. Her body was melting under the pleasant pleasure, yet she fought to hide it.

It was similar to how Eun-jung had looked when he first took her hand.

“Mmmh…”

Eun-su let out a low moan without realizing it.

She clamped her mouth shut in surprise, but it was already too late.

“You… what the hell is this… what are you doing to me?”

Tae-seok smirked and poured a little more strength into his grip.

“What am I doing? I’m just holding your hand. Why? Are you feeling something strange?”

At his words, Eun-su’s brows furrowed.

“No… that’s not…”

“When I held her hand like this… that’s right. Aunt Eun-jung’s face turned into exactly this expression. The kind of face that makes a man want to kiss her right away…”

Eun-su’s gaze wavered.

“What kind of bullshit is this… what kind of face am I making…”

Her face was filled with wariness, yet she never pulled her hand away from his.

“So… you know what I mean. I’m a man too…”

Tae-seok leaned even closer to her face.

Close enough that their lips could touch at any moment.

“And I kissed her just like this.”

Eun-su turned her head slightly to avoid him.

But she didn’t completely pull away.

“So you forced our sister into it like that?”

“That’s… I can’t quite remember. Whether I really forced her… or if we were both drawn to each other and wanted it…”

“What the fuck are you saying?”

“Auntie… why don’t you check for yourself?”

“Check what? Don’t— haa…”

Tae-seok didn’t wait any longer. He silenced her with his lips.

“Mmm…!”

Eun-su thrashed violently for a moment.

She pushed against his chest with both hands, trying to turn her head away, but the scorching energy pouring from his lips surged into her body.

Like an electric current, an intense wave of pleasure shot up from her lower belly all the way to the nape of her neck.

“Haa…!”

Her body stiffened for a split second, then went completely limp.

When Tae-seok pushed his tongue deep inside, Eun-su could no longer resist. She opened her mouth and accepted his tongue.

The moment his tongue wrapped around hers and sucked, another powerful surge of pleasure hit her.

The inside of her thighs grew slick and tingling. She instinctively pressed her legs together.

“Mmm… haa…”

As the kiss grew more intense, Eun-su panted heavily and wrapped both arms tightly around his neck.

Her body was already reacting beyond her control.

Her nipples had hardened into stiff peaks, and she could feel the inside of her leggings growing wet.

Still locked in the kiss, she muttered in a breathless voice.

“Fuck… what is this… just from your lips… my body… it’s so hot…”

She began sucking on his tongue more aggressively, pushing her own tongue into his mouth.

One hand gripped his hair tightly while the other raked down his back, pulling him closer.

“Haa…! I’m seriously going crazy… I’ve never been kissed like this before… you… what the hell are you?”

She was falling deeper into the kiss, twisting her waist slightly.

Her firm breasts pressed hard against his chest, and her thighs slipped between his legs, instinctively rubbing against him.

It was as if she no longer knew what she was doing.

Any sense of shame had vanished. She was shamelessly exposing her desire.

When Tae-seok finally pulled his lips away, Eun-su looked up at him with wet, glistening lips, breathing hard.

Her eyes were completely glazed over.

“Hey… keep going. If you stop now… I’ll really kill you.”

Her voice had melted completely, dripping with desperate lust.

“How about it? Did I force her? Or am I the only one who wants this kiss right now?”

“Why are you even asking? I already told you to keep going.”

Instead of answering, Tae-seok smiled and yanked her crop top up with both hands.

As the thin fabric brushed over her toned abs and rose higher, the perfect body of a thirty-four-year-old woman who trained every day was revealed all at once.

Her narrow waist, sharply defined abs from years of exercise, and the full, bouncy breasts straining against her bra.

When he tried to pull the crop top completely off, Eun-su raised her arms to help him.

Next, her bra was removed by his hands, and her firm breasts bounced free.

“They really are… perkier than Eun-jung’s.”

Tae-seok said as he grabbed both of her breasts with his hands.

“That’s… obvious. At least when it comes to my body… I’m better than my sister…”

She was already trying to appeal that she was the superior woman compared to her sister.

“Should I switch to you instead, Auntie?”

“You crazy bastard… haaang…”

Tae-seok immediately slipped his hand inside her leggings.

Because the tight leggings were squeezing her thighs and ass so firmly, the sensation of his fingers pushing through the fabric felt even more vivid.

The inside of her leggings was already soaked.

His fingers slowly rubbed the hot flesh inside her pussy.

“Mmmh…! Haa…!”

Eun-su’s waist jerked upward violently.

Her well-trained thigh muscles, befitting a PT trainer, clamped down hard around his arm and trembled.

She gripped his shoulders tightly with both hands, panting as she muttered to herself.

Haaang… what the hell is this… I usually hate it when guys touch me down there… but this feels way too good…

Tae-seok slowly peeled her leggings down.

Then he leaned her against the wall, lifted one of her legs, and hooked it around his waist.

With the leggings still dangling from one leg, her pussy was completely exposed.

“Do you want it all the way?”

Tae-seok deliberately pressed only the tip of his scorching cock against her entrance, slowly rubbing it up and down as he whispered.

The hot head grazed her already drenched folds, stimulating her clit.

Eun-su trembled, gritting her teeth.

“Yeah… I… I want it.”

Breathing heavily, she stared straight into Tae-seok’s eyes.

Her voice was filled with raw, honest desire rather than shame.

Still refusing to penetrate her, Tae-seok continued teasing her pussy with the tip of his cock, dragging it slowly upward.

“Really? I was only trying to prove a point… even though I’m the man your sister is seeing right now, you’re okay with this?”

At those words, Eun-su’s pupils shook violently.

My sister’s man.

That fact struck her mind like a hammer.

“Haaang~ What am I supposed to do… mmmh…”

“Tell me. Should I really put it in?”

“You son of a bitch… then you shouldn’t have gotten me this worked up in the first place. Haaang…”

The thought that she should say no flickered faintly through her mind, but the intense pleasure rubbing against her soaked pussy made it impossible to speak the words.

“Put it in. Put it inside me. I don’t care that you’re the guy my sister is seeing. Just… fuck me.”

Tae-seok chuckled softly at her words.

Then he brought his lips right next to her ear and whispered.

“Then… I won’t hold back.”

He still hadn’t pushed all the way in. He continued rubbing his glans against her entrance, stretching it open a few more times.

The moment her pussy twitched desperately, trying to suck him in, Tae-seok finally began to push his hips forward slowly.

“Aaaah…!!”

Eun-su’s head snapped back as a sharp moan tore from her throat.

Instinctively, she pushed against his chest with both hands, trying to pull her body back.

“Hey!!! What the hell are you putting in me? Is that… really yours?”

Eun-su hurriedly looked down between their bodies.

Her eyes widened in shock.

Her pussy was stretched wide open, and half of Tae-seok’s cock ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠was already buried inside her. The size was simply impossible.

“Crazy…”

Eun-su swallowed hard, unable to believe it.

The overwhelming size and thickness she was seeing for the first time filled her with genuine fear.

Tae-seok savored her reaction and lifted his hips slightly, pushing even deeper.

“Haaak…! It’s too… big… and so hot…”

Eun-su moaned through gritted teeth.

“Haa… haa… this is insane… how can any woman stay sane after taking something like this…”

“You saw that Aunt Eun-jung was perfectly fine.”

Eun-su buried her face in his neck, whispering almost tearfully.

“Haaang… what am I going to do… aaang~”

Her firm, exercise-toned thighs clamped tightly around his waist. Her pussy squeezed his cock with a sticky grip, as if it refused to let go.

Tae-seok grabbed her ass with both hands and began thrusting in earnest.

Slap! Slap! Slap!

Every time her back slammed against the wall, her breasts bounced wildly.

Fuck… her body is seriously insane. Eun-jung has become incredible lately too, but her little sister has been maintaining herself constantly, so it’s on another level. I wonder what this body would become once it receives my ‘Blessing of Beauty’ buff?

Eun-su’s pussy still hadn’t adjusted to the unprecedented size and simply kept clenching tightly around his cock.

“Haa…! It feels… so good… I never knew being this full could feel this amazing.”

She didn’t hide her feelings at all. Instead, she moaned even more ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lewdly as she clung to his neck.

Her elastic, flexible body responded perfectly to his movements. She began rocking her own hips, taking him even deeper.

Tae-seok pressed his lips to her ear and growled roughly.

“Now do you understand… why Aunt Eun-jung gives her body to me?”

At those words, Eun-su’s body trembled violently.

With her face buried in his shoulder, she swallowed hard and answered.

“Damn ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it… I think I get it now… if someone fucked me with a cock like this every day… who the hell could resist…”

The moment she finished speaking, she pulled his neck harder and shoved her tongue into his mouth.

Her pussy squeezed his cock even more fiercely, gushing hot nectar.

“Harder… fuck me harder… harder than you did to my sister…”

After the sex ended, Tae-seok’s room was filled with the sound of their heavy breathing and the thick scent of her juices.

Eun-su remained slumped against the wall for a long time, unable to stand.

Hot semen dripped stickily down the inside of her thighs, and her swollen pussy twitched rhythmically.

She gritted her teeth and slowly pushed herself up.

Then she began pulling up the leggings that were still tangled around one leg.

With her legs slightly pressed together and her waist bent forward, she slowly dragged the leggings upward.

As the tight fabric squeezed her sweat-slicked thighs, the semen still leaking out smeared glossily against the inside of the leggings.

“Haa…”

She let out a small sigh.

The moment the leggings fully covered her ass, her swollen pussy was pressed hard against the fabric, making the sticky sensation even more vivid.

After pulling the leggings all the way up, she slipped her crop top back on and ran a hand over her breasts.

The thin top, worn without a bra, clung wetly to her sweat-covered chest, shamelessly revealing the shape of her breasts.

Eun-su glanced at herself in the mirror, her hair a tangled mess.

Confused thoughts flooded her mind.

How did it come to this… I just came out of curiosity to see what kind of guy my sister was seeing… and ended up getting completely wrecked by some kid…
