The Sister-in-Law's Feeling
As the third glass emptied, Gi-cheol's eyes were already glazed.
It wasn't just the alcohol.
His pent-up dissatisfaction with his marriage to Eun-su, the grievances that had piled up over time, and the gentle gaze of his sister-in-law listening intently to his story right now—all of it was slowly dismantling his defenses.
He poured everything out.
The moments Eun-su had ignored him, the marriage where lonely nights outnumbered the ones they shared, and now the divorce lawsuit hanging over them.
"Sister-in-law... I was so lonely."
Eun-jung pretended to listen closely, but her mind was elsewhere.
What expression would make him lust after her? What posture would draw his eyes to her body?
Just a little more... I need to make him want me. Make him crave my body.
She had long since shifted to the seat beside him. Her thigh pressed against his.
"Gi-cheol. Why did you just endure everything like that? Like an idiot..."
She called him by name. The atmosphere was nothing like the stiff "brother-in-law" she had used after the wedding. Not "Mr. Gi-cheol," not "brother-in-law"—just "Gi-cheol." That single word carried an intimacy that made his heart flutter.
Her empathy drew him closer, made him lean on her.
"……Noona."
He answered with the familiar address instead of the formal title.
Eun-jung's hand settled lightly on his knee, then began a slow, deliberate slide up the inside of his thigh. Every inch her fingers traveled sent tension rippling through his muscles.
Ah... Noona's hand... Is she really seducing me? Because she's drunk? Well... she's been without a man for too long too.
Something stirred beneath his pants.
"Sometimes I even wonder if marrying noona would have made me happier."
His voice had dropped. Eun-jung's lips curved slightly.
"Really? Actually... I've thought the same thing sometimes..."
She leaned in, lips brushing his ear as she whispered. The scent of liquor mingled with her perfume, flooding his senses.
"You must have had such a hard time, Gi-cheol..."
The low murmur against his ear carried a subtle fragrance.
"Noona... right now... is it okay if I misunderstand this?"
He lifted his head and met her eyes. They were far too close. One more step and they would cross a line with no return. His heart hammered.
"It's not a misunderstanding."
Eun-jung moved first. She wrapped her arms around his neck and pressed her lips to his.
"Noona... hah..."
Her tongue slipped between his lips. Gi-cheol's body went rigid. He had imagined this kiss countless times, never believing it could become real. Yet here it was. His head spun. His lips began to move with hers, tongues seeking, tangling, sucking until breath grew short.
Chup... churup...
The wet sounds of saliva filled the room as their breathing turned ragged. Instinct took over. Her beautiful face, her voluptuous body, the way her breasts swayed before his eyes—all of it stoked the fire inside him. Every stroke of her fingers through his hair sent shivers racing down his spine.
Before he realized it, his hand had slipped beneath her skirt, gliding up her thigh. Eun-jung caught his wrist and stopped him.
"Gi-cheol... only this far. We can't go any further. Really... just this much..."

Even as she spoke, she knew he would not stop now. She also knew those words would only pour fuel on his burning desire.
As expected, he sucked harder at her lips and pulled her body onto his. Eun-jung climbed naturally into his lap. Her skirt rode up, exposing her panties.
Sex with his beautiful sister-in-law. The thought alone set his body aflame.
Her hand slid down over his pants, finding the already rigid length. Gi-cheol could hold back no longer. He laid her down on the sofa.
"……We shouldn't do this."
Eun-jung turned her head and spoke softly. Even this was part of the performance meant to provoke him.
"Noona started it."
Gi-cheol's voice was low and rough, his eyes long since stripped of reason. Only raw desire burned there.
"Yeah... I know."
Eun-jung answered briefly. When his hand moved to remove her panties, she gently caught his wrist.
"Not here... let's go to the bed, Gi-cheol."
Her eyes already promised she would give him everything. Suggesting the bed was simply another step in that surrender.
"All right."
Gi-cheol lifted her effortlessly, one hand supporting her buttocks, the other cradling her back, and carried her toward the master bedroom. With every step, her heated center brushed against his hardness.
"Huu..."
"Haa..."
Both swallowed soft moans at the same time.
The moment they reached the bed, he laid her down roughly. As her back met the soft blanket, he climbed over her. Eun-jung spread her legs wide in welcome. Though bound by marriage, the sight of the woman who had once been family opening herself to him was unbearably arousing.
Her hand reached down and grasped his cock.
"So impressive. Eun-su with something like this..."
"Don't talk about Eun-su. I'm going inside noona now."
Gi-cheol's voice was low and harsh. No hesitation remained in his eyes—only Eun-jung. His wife's older sister. His sister-in-law. None of those titles mattered anymore.
"Yeah... come inside me."
Eun-jung's voice was sweet, yet carried a faint tremor. She guided his glans to her entrance, her folds already slick and hot. The moment they touched, both held their breath. Time seemed to freeze. After this, there would be no going back. Every taboo was about to shatter. There were no more "what ifs." This was happening now.
Gi-cheol drove his hips forward in one powerful thrust, burying himself to the hilt.
"Ugh... noona...!"
"Aaang...!"
Their moans erupted together. His cock pushed deep into her pussy, the walls parting to accept him. The sensation resisted yet pulled him deeper at the same time. Gi-cheol's mind went blank. Eun-jung's pussy was astonishingly hot and velvety. His wife Eun-su's body, honed by exercise, had been firm and elastic. Eun-jung was different. Though she lacked some of that tightness, she possessed the ripe allure of a mature woman. The way her walls clung and sucked at him was incomparably more pleasurable. If Eun-su's pussy felt like it squeezed, Eun-jung's felt like it melted around him.
The deeper he sank, the hotter and stickier her response became.
"Haa... noona... you feel so good..."
While Gi-cheol lost himself in admiration, Eun-jung felt no sexual pleasure. Only a cold sense of accomplishment.
Haa... I... really did it. My brother-in-law's cock... finally...
She had carried out Tae-seok's orders faithfully and achieved her goal. That alone satisfied her. No matter how roughly Gi-cheol moved or groped her body, nothing compared to this triumph.
Slap... slap...
The wet sound of flesh meeting flesh filled the room.
"Noona... I like it so much... I'm going crazy... haak..."
Then an unexpected line slipped from Eun-jung's lips.
"Crazy... you actually put it in. We can't do this. I'm... Eun-su's older sister."
Her voice turned cold. The woman who moments ago had clung to his neck and breathed hotly against his skin suddenly grew distant. Gi-cheol froze, still buried deep inside her. The warm, slick, clinging sensation still burned against his lower belly.
What the hell... after seducing me so hard...
Something felt wrong.
"Noona... what are you saying now of all times..."
"You bastard... what did you do to me? Pull it out. This is wrong..."
Eun-jung's eyes were icy, yet her pussy tightened around him even more greedily. Gi-cheol swallowed hard. The urge to withdraw clashed violently with the overwhelming pleasure. Why had she changed so suddenly after being so aggressive? Separate from the confusion, the pleasure kept rising. Every squeeze of her walls made him more sensitive. The urge to come surged. He bit his lip, trying to hold back, but he was already at his limit.
At that moment—
Click...
The door opened. Eun-su stepped inside, phone raised, lens pointed straight at them.
"You bastard... what the hell are you doing to our sister right now?"
Eun-su's voice rang cold through the room. Gi-cheol's face drained of color. He stopped, panicked, yet his body refused to move. Beneath him, Eun-jung slowly turned her head toward her younger sister. No trace of surprise or embarrassment remained on her face. Instead—
It's done.
A faint smile curved her lips. Everything had gone exactly as Tae-seok planned.
"Eun... Eun-su... this... it's not what it looks like..."
Gi-cheol stammered. Eun-su only stared at him with icy eyes. At that instant, Gi-cheol lost the last of his control and came inside Eun-jung, the act captured clearly on camera.
"Aak... this is..."
"Crazy bastard... to our own sister..."
Eun-su's low voice cut sharper than any shout.
"Ha... haak... this... really..."
Gi-cheol tried to speak, but his thoughts refused to form.
