Mornings started late—usually around 10 a.m.—with him rolling out of bed in his modest apartment on the outskirts of Seoul. His parents were both working professionals: Dad at a tech firm, Mom at a hospital, leaving the place empty most days. Jaegun would shuffle to the kitchen, brew a strong cup of instant coffee, and scroll through his phone, liking memes on Instagram or debating K-pop theories in group chats with his buddies.
By noon, he'd hit the gym. Jaegun wasn't built like a bodybuilder, but he was strong—lean muscles from years of soccer and hapkido classes, broad shoulders that made his t-shirts hug just right, and a height that towered over most of his friends at 185 cm. His dark hair was always tousled in that effortlessly cool way, and his sharp jawline paired with mischievous brown eyes gave him a handsome edge that turned heads without him trying. Girls at school had whispered about him, but Jaegun was witty more than flirtatious; he'd crack jokes to deflect compliments, turning potential awkwardness into laughter.
After the gym, lunch was usually ramyeon or whatever leftovers he could microwave. Afternoons varied: sometimes binge-watching Netflix, other times tinkering with his computer, dreaming of starting a gaming channel on YouTube. Evenings brought social life—hanging out with friends, grabbing street food, or just wandering the neon-lit streets of Hongdae. It was routine, comfortable, but with a nagging itch for something more exciting. Little did he know, excitement was about to knock—literally.
One sunny Thursday afternoon, Jaegun decided to drop by Minho's place. Minho was his best friend since middle school, the kind of guy who'd back you up in a fight or share cheat codes for exams. They lived about 20 minutes apart by subway, and with nothing better to do, Jaegun texted: "Yo, home? Bored af." Minho replied instantly: "Come over, parents out, got new PS5 game."
Jaegun grabbed his backpack, tossed in some snacks, and headed out. The ride was uneventful, his earbuds blasting hip-hop as he watched the city blur by. Minho's family lived in a upscale apartment in Gangnam—his dad was some corporate exec, mom a homemaker who volunteered at charities. Jaegun had been over countless times, but today felt different. Maybe it was the heat wave making everything sticky, or the post-grad buzz still lingering.
He buzzed the intercom, and Minho let him in. "Dude, you're late. I already died twice in this level," Minho grumbled as Jaegun kicked off his shoes in the foyer. The apartment was sleek: marble floors, modern art on the walls, a balcony overlooking the Han River. They settled in Minho's room, controllers in hand, trash-talking each other over virtual battles.
An hour in, Jaegun's throat was dry. "Gonna grab some water," he said, pausing the game. Minho nodded, eyes glued to the screen. Jaegun wandered to the kitchen, but a splash from the balcony caught his ear. Curious, he peeked through the sliding glass door.
There she was: Minho's mother, Mrs. Kim—or as Jaegun knew her, the stunning woman who looked like she stepped out of a K-drama. But today, she was lounging by the small rooftop pool they had installed last year, wearing a skimpy red bikini that left little to the imagination. Jaegun froze. She was the spitting image of Jun Ji-hyun, the actress from those blockbuster movies—tall, elegant, with flawless porcelain skin, long wavy hair cascading down her back, and a figure that screamed confidence. At 42, she didn't look a day over 30: full breasts straining against the bikini top, a toned waist from yoga classes, and legs that went on forever, glistening with sunscreen under the sun.
She was reclining on a lounger, sunglasses perched on her nose, flipping through a magazine. The way the fabric hugged her curves, the slight sheen of sweat on her cleavage—it hit Jaegun like a punch. He'd always noticed her beauty in passing, but this? This was temptation incarnate. His heart raced, blood rushing south as he stared, transfixed. "Damn," he muttered under his breath, feeling a stir in his jeans.
As if sensing eyes on her, she looked up, lowering her sunglasses. A slow, knowing smile spread across her lips. "Jaegun-ah? Is that you?" Her voice was sultry, like velvet, with that melodic lilt that made everything she said sound inviting.
He swallowed hard, stepping out onto the balcony to play it cool. "Uh, yeah, Mrs. Kim. Just getting water. Didn't mean to interrupt your... sunbathing." His wit kicked in, but it faltered. "You look like you're auditioning for a beach commercial. Jun Ji-hyun would be jealous."
She laughed, a light, tinkling sound that sent shivers down his spine. Setting the magazine aside, she sat up, the movement making her breasts bounce slightly. "Flattery from a handsome young man like you? I'll take it." She patted the lounger next to her. "Come sit. Minho's probably glued to that game, right?"
Jaegun hesitated, but his feet moved on their own. He sat, trying not to stare at the way the bikini bottom rode up her thighs. Up close, she smelled like coconut oil and something floral—intoxicating. "Yeah, he's in his zone. So, uh, hot day, huh?"
"Very hot," she purred, her eyes roaming over him appreciatively. Jaegun was in a simple tank top and shorts, his muscles on display from the gym earlier. "You've grown up so much, Jaegun. Strong, handsome... quite the man now." Her hand brushed his arm lightly, sending electricity through him.
He chuckled nervously, wit surfacing as a defense. "Careful, Mrs. Kim. If you keep that up, I might think you're trying to recruit me for your charity events—as eye candy."
Her smile turned seductive, eyes darkening. "Maybe I am. Or maybe I just like what I see." She leaned closer, her bikini top gaping slightly, offering a glimpse of her nipples. "You've been glancing at me for years, haven't you? Those quick looks when you think I'm not noticing."
Jaegun's face heated. It was true—he'd stolen glances during family dinners, admiring her grace. But this? "Mrs. Kim, you're my best friend's mom. This is... not right." Inside, his body betrayed him; his cock twitched, hardening against his will.
She placed a hand on his thigh, inching upward. "Call me Ji-hyun. And what's wrong with a little fun? You're young, virile... I could use some excitement." Her fingers grazed the bulge in his shorts, making him gasp.
"No, wait—" He stood abruptly, heart pounding. "I can't. Minho's right inside. This is messed up." But god, he wanted her. The temptation clawed at him, visions of ripping off that bikini flashing in his mind.
Ji-hyun pouted, standing too, her body brushing against his. "Come on, Jaegun. Just a taste." She pressed her breasts against his chest, lips inches from his.
With sheer willpower, he stepped back. "I gotta go. Tell Minho I felt sick or something." He bolted inside, grabbing his bag, ignoring Minho's confused shouts. Out the door, down the elevator, his mind raced. What the hell just happened? He couldn't control the erection tenting his shorts on the subway ride home, replaying her touch over and over.
Back at his apartment, Jaegun paced, trying to shake it off. A cold shower helped, but the image of Ji-hyun in that bikini lingered. He crashed on the couch, watching TV to distract himself. Evening fell; his parents texted they'd be late—work dinners. Alone, he ordered pizza, munched absentmindedly.
Around 8 p.m., the doorbell rang. "Pizza guy's early," he muttered, heading to the door. But when he opened it, there she was: Ji-hyun, in a tight black dress that hugged her curves like a second skin, heels making her legs look endless. Her hair was down, makeup sultry—red lips, smoky eyes. She looked every bit the actress she resembled.
"Ji-hyun? What are you—" Before he could finish, she pushed him inside, slamming the door behind her. Her hands fisted his shirt, yanking him down for a fierce kiss. Her lips were soft, demanding, tongue invading his mouth with hunger.
Jaegun's shock melted into desire. He kissed back, hands gripping her waist, pulling her flush against him. She moaned into his mouth, the sound vibrating through him. Breaking the kiss, she whispered hotly against his ear, "I've wanted this for so long, Jaegun. The way you look at me... those stolen glances. You think I don't notice? Your eyes on my body, undressing me."
He pulled back slightly, breathless. "This is crazy. Minho—"
"Forget Minho for tonight," she said, eyes blazing. "My husband... he's been cheating on me for months. With his secretary, some young thing. I found the messages. So why shouldn't I have what I want? And I want you—strong, young, handsome you." Her hands roamed his chest, nails scraping lightly. "You've grown into such a man. Let me show you how good it can be."
Jaegun's resolve crumbled. "Well, if you're offering a masterclass, who am I to say no?" His wit returned, masking the raw lust. "But only if you promise not to grade me too harshly."
She laughed, low and throaty. "Oh, I'll grade you... and reward you." Grabbing his hand, she led him to his bedroom, hips swaying hypnotically. The door clicked shut behind them.
Inside, the room was dimly lit by a bedside lamp—posters on the walls, a messy bed from his lazy morning. Ji-hyun pushed him onto the mattress, straddling him in one fluid motion. Her dress rode up, revealing lace panties. "God, you're hard already," she murmured, grinding against his erection.
Jaegun groaned, hands sliding up her thighs. "Can you blame me? You're like a walking fantasy." He flipped them, pinning her beneath him, kissing her neck. She arched, fingers tangling in his hair.
"Take off my dress," she commanded, voice husky.
He obliged, unzipping it slowly, savoring the reveal. The fabric pooled around her waist, exposing her bare breasts—full, perky, nipples hardened peaks. "No bra? Bold move, Mrs. Kim."
"Ji-hyun," she corrected, pulling him down to suckle one nipple. He latched on, tongue swirling, teeth grazing. She moaned loudly, "Yes, just like that. Bite harder."
He nipped, eliciting a gasp. "Bossy, aren't you? I like it." His hand slipped between her legs, rubbing her through the lace. She was soaked, hips bucking.
"Inside me, now," she demanded, tugging at his shirt. He stripped it off, revealing his toned abs. Her eyes devoured him. "So strong... fuck me like you mean it."
Jaegun shed his shorts, cock springing free—thick, veined, throbbing. Ji-hyun licked her lips, wrapping her hand around it. "Impressive. Bigger than my husband." She stroked, thumb circling the tip.
He hissed, "Flattery will get you everywhere." Pushing her panties aside, he positioned himself, rubbing the head against her slick folds.
"Don't tease," she whined, wrapping her legs around him.
With a thrust, he buried himself deep. She cried out, nails digging into his back. "Oh god, yes! So full..."
Jaegun set a rhythm, slow at first, savoring her tightness. "You feel amazing. Like velvet." He sped up, hips snapping, bed creaking.
"Faster, harder!" she urged, meeting his thrusts. "Fuck me like a slut."
His wit sparked: "Your wish is my command, milady." He pounded into her, one hand pinching her nipple, the other rubbing her clit. She screamed, walls clenching.
"I'm close—don't stop!"
He grunted, sweat dripping. "Come for me, Ji-hyun. Let go."
She shattered, body convulsing, juices flooding. "Jaegun! Yes!"
He followed, pulling out to cum on her stomach, ropes of hot seed painting her skin.
But they weren't done. Panting, she flipped him over, mounting him reverse cowgirl. "My turn." She sank down, riding him wildly, ass bouncing.
Jaegun gripped her hips, thrusting up. "Ride me, baby. Show me what that actress body can do."
She laughed breathlessly. "Like this?" She ground circles, clenching around him.
"Fuck yes." He spanked her ass lightly. "Harder."
She obliged, moans echoing. They switched positions—doggy style, her on all fours, him slamming from behind. "Pull my hair," she begged.
He fisted her waves, yanking gently. "Like this?"
"Harder!" He pulled, thrusting deep. She came again, sobbing his name.
Missionary next, legs over his shoulders for deeper penetration. "Look at me," he said. "I want to see your face when you cum."
Eyes locked, she whispered, "You're ruining me for anyone else."
"Good," he smirked. "Consider it a service."
They fucked for hours, exploring every angle. Spooning, her back to his chest, his hand between her legs. Standing against the wall, her leg hooked around him. On the floor when the bed got too messy.
Dialogue flowed amid gasps: "Deeper, Jaegun—oh fuck!"
"You're so tight, Ji-hyun. Made for this cock."
"Bite my neck—mark me."
"Careful, or Minho might notice."
"Forget him. Just fuck me."
By the end, they collapsed, bodies slick, room reeking of sex. Jaegun traced patterns on her back. "That was... intense."
She smiled, kissing him softly. "Worth the wait. But this isn't over."
He grinned. "Round two tomorrow?"
