The Ecstasy Behind the Thin Wall
He felt an unexpected firmness in the ass his hand had seized.
'Whoa… the landlady's ass feels like this?'
The real estate agent, around his own age, had a body so well-maintained that the aunties back in his hometown would have seemed almost apologetic in comparison. But however diligently someone took care of themselves, age couldn't quite be fooled—she didn't have that springy, bouncy feel.
The landlady's ass was in a league of its own. Right now, it felt every bit as firm as Gayoung's had just last night.
That delightful elasticity made his hand impossible to keep still. Seran flinched each time he squeezed, but even so, she never once let his cock slip from her mouth.
Watching her offer no resistance, Si-woo grew curious just how far she would let him go. He slid his hand down and slipped it under her skirt.
Where there should have been a thin scrap of fabric, he felt only the soft touch of bare skin.
'…Nothing. She's not wearing any.'
He hesitated for a moment, wondering if he should stop here—but having come this far, he didn't want to quit. Boldly, Si-woo pushed his hand deeper.
The overflowing firmness he'd only felt through the fabric was far more satisfying up close. No matter how tightly he gripped, the shape refused to give; if anything, it seemed ready to bounce his hand right back off.
"Mmmh…"
Seran's lips, wrapped around his cock, parted slightly, and a shallow moan leaked out.
Si-woo began moving his hand toward her center. The rounded curve crested at the top of its rise, then the descent began. His groping hand now had only one final destination ahead of it.
'Is this okay?'
He kneaded her ass absently, buying time. And then, the woman who had been silently watching him moved.
As Seran shifted her body, Si-woo's hand came to rest, at last, on a pussy that was soft but burning with heat.
'…You're soaked, aren't you?'
She was damp—no, drenched. The lightest touch alone was enough to soak his finger through.
Seran adjusted her position little by little, grinding her ass against him, and his fingers naturally burrowed inward.
"…Mmmn."
A deeper moan spilled from her parted lips.
As he moved his fingers, Si-woo felt an especially smooth texture at his fingertips, deep in the crevice. His finger pushed into that furrowed place.
Sqelch.
"Haahk…!"
The springy inner flesh bit down on his invading finger, again and again. Seran, overwhelmed by the electricity surging up from below, had bent completely forward, her ass bucking in the air.
Si-woo's finger, buried inside her, churned her insides like a fish meeting water.
"Haah… S-Si-woo… haah…"
Seran panted in short, rhythmic breaths, her whole body trembling. Squelch, squelch. His finger, drenched in her juices, began to pump her pussy as if it lived there.
Si-woo lifted his body and flipped her skirt up. In the very center of her white, plump ass, his finger vanished and reappeared, over and over.
Seran was on all fours, ass raised high, completely bent over.
"Haah… haah…"
He wasn't the only one who was worked up. Wanting something other than a finger inside her, Si-woo positioned himself and aimed his cock at her hole.
"S-Si-woo… t-this isn't right…"
Seran tried to cover herself with both hands, but she was no match for a young man this aroused. She pulled her hands away, and he pressed the tip of his cock against her hole, which was already sputtering frothy fluid.
"Haah… haah. I'm sorry, ma'am. But I can't hold back anymore."
With a soft push, he tensed his hips—and the cock that touched her hole seemed to be swallowed whole, disappearing inside.
"Haak!"
Seran clamped her mouth shut, trying to hold back the moans bursting out of her.
Like a starving beast that had caught the scent of prey, Si-woo pounded into her like a madman. Thwack, thwack, thwack.
Come to think of it, lately he'd hardly had a moment for his lust to build up. Ever since he'd come up to Seoul, the string of events had left him almost worried he'd run dry.
And yet, in this moment and this moment alone, desire surged up in him like he was a man fresh out of a life of abstinence. The depravity of the situation—a boy of twenty taking a woman old enough to be his mother, his own landlady no less—intoxicated him with an excitement he could barely contain.
Hah, hah, hah. His breathing was as ragged as if he'd sprinted at full speed.
Seran struggled to endure the young man's frenzy from next door. The force of his thrusting nearly broke her pose again and again, but unwilling to shatter the moment, she held on with everything she had.
But perhaps because the fire had caught too quickly, it didn't burn for long. Unable to control himself, Si-woo reached his climax after only a few strokes.
"Ngh… M-Ma'am…!"
Spurt, spurt, spurt. Thick ropes of cum slammed into Seran's insides again and again.
"Haahhh… haahhh…"
When he finished and pulled out, the overflowing semen ran down her body and dripped, drop by drop, onto the floor.
Seran said nothing, simply catching her breath as she calmly wiped away the fluids trickling down her. After cleaning even the last bead of cum clinging to the tip of his cock, she gathered up her clothes and began to dress.
"M-Ma'am…"
Lost in the awkward silence, unsure of what to say, Si-woo finally found his voice as he watched her retreating figure toward the door. Seran turned her head slightly and answered with a quiet, smiling look—then the door clicked shut.
His legs gave out, and Si-woo collapsed onto his back on the floor.
"Haah… you idiot… how am I supposed to face her now? Surely she's not going to kick me out…?"
Strangely, the worry that he might lose this sweet arrangement swept over him before any guilt for having his way with a middle-aged woman.
And honestly, he had plenty of reason to feel that way.
"Come to think of it… wasn't she the one who seduced me first?"
She had barged into his bathroom uninvited, offering to help him masturbate—that was where all of this had begun.
"…No, wait. If anything, it started when she moaned that loudly in a place with paper-thin walls like this…"
Si-woo kept digging for justifications. "That's right… she was soaked, not me. I was practically the victim here…"
Whatever the case, the events were already behind him, and evening was falling. The sunset sky was turning red well before dinnertime, and just as the clock struck six, the doorbell rang.
Click.
There stood Seran, flashing him a bright smile. The only difference from that morning was that her hands were empty.
"You haven't eaten yet, have you? Would you like to come eat at my place tonight?"
At her single remark, Si-woo's worries melted away like snow. "Yes, I'll come right over."
Delighted, he slipped on his slippers and followed the landlady out.
"Would you sit and wait a moment?"
After seating Si-woo, Seran took off the cardigan she had draped over her shoulders.
Watching her, Si-woo barely managed to keep his jaw from dropping. Because what emerged from beneath that cardigan was a dress—little more than nightwear—with half her upper body on full display.
Sensing his reaction as she pulled it off, Seran gave a shy smile. "Oh my… I'm sorry. The moment I stepped inside, it felt like home, and I forgot I had a guest. I got too comfortable…"
She started to drape the cardigan back on, changing the direction of her movement, but Si-woo quickly waved his hands in protest.
"N-no, please. You should be comfortable in your own home, of course."
Seran hesitated at his strained voice. "But if it makes you uncomfortable…"
Si-woo shot up from his seat and blurted, "Never! It's absolutely not uncomfortable, so please don't worry about it."
Startled by his own outburst, he froze—while Seran burst out laughing.
"Pfft."
"Alright then. I'll stay comfortable."
With the cardigan fully off, the dress hung loose from thin spaghetti straps, and her chest was so exposed that only her nipples stayed barely covered, her full upper swell on complete display.
Si-woo swallowed the pool of saliva in his mouth with an audible gulp, afraid it might actually drip.
The clink of spoon against bowl was the only sound filling the quiet space.
'The landlady's place is… how should I put it? Like a house no one actually lives in.'
The overly tidy home felt somehow empty, as if it were just for show.
With a few practiced movements, the landlady set the table, took her seat, and their dinner began. But Si-woo found it nearly impossible to focus on the food. Every time he lowered his head, his eyes were drawn, helplessly, to the cleavage on full display.
Clang.
"Oh my… Si-woo, sorry, but could you grab that spoon for me?"
"Sure, one second."
The metallic clatter brought him back to his senses, and he bent down to pick up the spoon under the table. And the moment he started to rise, Si-woo had no choice but to doubt his own eyes.
Between Seran's parted legs, her bare pussy was openly, shamelessly on display.
'Holy… she wasn't wearing any panties…?'
Fine, she was comfortable at home—but wasn't this crossing a line? Then again, they'd already seen everything there was to see of each other, so maybe this hardly mattered anymore.
"What's wrong, Si-woo?"
Seran leaned forward, peering at him as he stalled.
"N-nothing. The spoon just rolled a bit far, that's all."
With a strained grunt, Si-woo pulled himself back up.
"Thank you."
Taking the spoon from him, Seran—whether or not she'd noticed his heated gaze—returned to her meal.
"Thanks for the meal."
"It's so nice having someone to share a meal with. Well then, have a good evening."
Back in his own room, Si-woo leaned against the wall.
"…Haah."
The image of the landlady's bare pussy flickered before his eyes.
"…Maybe I should have just pounced on her one more time?"
He told himself she probably wouldn't have refused, given what they'd already done—but if he pushed his luck, he might genuinely end up getting kicked out of his room.
"…Okay. Restraint. Restraint."
He squeezed his eyes shut, but the tighter he squeezed, the more vividly he could see it: the feel of her flesh from last night.
"It's fine if it's just by myself."
Si-woo tugged his pants down. His angry cock sprang free with a bounce.
With practiced ease, he gripped himself and began to stroke. He'd barely gotten into a rhythm when, from somewhere beyond the wall, he heard a woman moaning.
Si-woo froze and pressed himself close against the wall.
"…Haah, haah…"
By now, the landlady's moans were familiar to his ears.
"…Si-woo… haah… haah…"
