Chapter 41: The Forbidden Night of Pleasure
I pressed my ear slowly against Jin-yeong's closed bedroom door, barely breathing, desperate to catch even the smallest sound.
The soft rhythm was unmistakable now: swish, swish, thump, thump—the slick slide of skin on skin, the blanket sliding across the sheets, the wet, urgent rhythm of Suyeon taking her son's thick cock deep inside her.
“Aaa… Ahn… Jin-yeong… ah…”
“Oho, Suyeon-ssi, shh… you’ll wake Dad downstairs.”
“Hngh… I know, I know… just don’t say my name… aaahha… I feel so guilty toward Dad… really…”
For the first time since I’d forced her to swear she would never cheat, the rule shattered the instant I was out of earshot.
From the notes I’d read in his diary, Suyeon’s usual excuse had always been the same: Just this once. Never again. At first she’d clung to it like a lifeline, but slowly, guilt turned to hunger, and now the “just this once” had become an addiction.
That was why she’d agreed to this family vacation at the pension. She’d believed the house was off-limits—especially while I was here, playing the doting husband. But the moment the bedroom door closed and I fell asleep on the first floor, her body betrayed every vow.
I could feel the heavy, insistent weight of my own erection pressing against my lower belly. My hand wrapped around it and I started stroking, slow and furious, matching the pace I imagined she was using on him.
Swish… schlick… smack, smack
The wet sounds had become so familiar I could almost picture myself sliding into her instead—her tight, dripping heat gripping me, her soft thighs wrapped around my hips, her desperate moans filling the room.
I pressed my ear harder against the door, eyes closed, lost in the fantasy.
“Aaa… I’m going to cum… ugh… it feels so good…”
“Jin-yeong, inside… fill me… aaah…”
“Ah… Mom’s doing a full storm piston… aaaaaah!”
“Haaahaaa… so deep… you’re stretching me so full…”
The bed creaked violently. Even with me downstairs, Jin-yeong was giving it everything he had tonight—like he thought it was the only night he’d ever get.
Jealousy burned in my chest, hot and sharp, but my cock throbbed harder, betraying me completely.
“Aaaa… Mom… I’m cumming…!”
“Mmm…”
The powerful thrusts slowed, then stopped. The room fell into sudden, heavy silence except for their ragged breathing.
I lowered my head and stared at my own throbbing dick. A thick rope of cum had spurted out without me even realizing it, splattering across the floor and staining the doorframe right in front of the bedroom.
“Hah… shit…”
Embarrassment flooded me. I hadn’t expected to cum just from listening. The taboo, the voyeurism, the raw heat of it all—it had been too much.
I had nothing to clean it with. My only choice was to pull down my underwear, wipe the mess on the floor with my panties, and slip them back on, cheeks burning.
From the other side of the door, their voices drifted down—low, intimate, still catching their breath.
“Huu… what am I going to do? Dad’s right downstairs…”
“…”
“But that look you gave me while you were pushing Dad into the water earlier? So hot. You looked just like Dad when he was younger. My heart was racing the whole time.”
“Hehe… you’re biased. It’s only natural for a son to be like that.”
“The way you checked if Dad was breathing after you lowered him to the beach… so adult. I just wanted to give you everything I could.”
“Ah, so the unexpected gift you gave me was actually me?”
“Hehe! Exactly. I’m sorry to Dad… but this one time only, okay?”
“Mmm. Mom knows how much Dad loves you better than anyone. Don’t feel bad. I love Dad even more as a son, and Mom… hehe.”
“As a son? You’d be happy if that was all I gave you?”
“Really? Your words and your actions are totally opposite, Suyeon-ssi. Last time in the car you almost drove away right in front of me…”
“Ah~ that’s different… argh… you really are something else, my son. Sometimes I see Dad’s younger face… or I just don’t know…”
“So how about one more round, Suyeon-ssi?”
“I don’t know… hurry up. At least Dad’s drunk and asleep down there…”
Busuk, busuk
“Put the condom on.”
“Mmm, Mom will put it on for you.”
“Haa… come here.”
Ssuk… swish… smack
“Aah! Does it hurt? Not a spanking, right? A cock spanking?”
Suyeon had probably flicked the tip of the condom against his cock to stretch it tighter. She used to do the same thing for me—her soft, skilled hands wrapping me up so carefully and sensually that I’d often cum in the middle of putting the condom on.
“Kyaa… ehehe, Dong-yeon-ssi, did you cum?”
“Eep… eep… I-I don’t know… every time you move like that for me it just feels so good… I’m so embarrassed… hah…”
Suyeon was truly incredible. Her control, her teasing, her total surrender to desire—it always left me stunned.
“Jin-yeong, your cock is way too big. This condom isn’t going to fit all the way… how are you even that big? Dad wasn’t this huge, you know?”
“Hmph… that’s because Mom’s genes combined with Dad’s to create something even more magnificent… mmm…”
I could already picture the playful wink he’d give her as he said it.
His cheerful, caring personality made him the perfect son—always trying to make the person he loved feel good.
“Hehe, you’re not bad at all.”
“Mom, I’m ready. Here I go.”
“Mmm, go slow for me.”
Suyeon had probably lain back on the bed, legs spread wide, waiting for her son’s massive cock to push into her dripping pussy.
I didn’t need to see it. The sounds alone were enough.
I focused every nerve in my body, ear pressed to the door, listening to every wet slap, every moan.
A few seconds later:
“Aaa…”
“Eep… Mom…”
“It’s in… aaah… how are you so big…”
Suyeon’s soft cry was barely audible, but it was the same broken, ecstatic sound she used to make for me—except now it was for another man… her own son.
“Aaa… Mom… so many hands inside you, squeezing me… I’m going crazy…”
“Ah… that’s not it. It’s just that you’re filling me up so completely…”
“Yeah… it’s not all the way in yet. When will it finally fit? Hah… hah…”
“No way… is it really that big? Oh my god… I’m already feeling too full… aaah…”
“…”
Their voices faded into soft, overlapping gasps.
Thud, thud, thud
Nothing but the raw, rhythmic sound of flesh slapping against flesh.
Jin-yeong was pounding Suyeon’s pussy with everything he had.
I wasn’t sure if this was a dream or reality anymore. The hangover and the way my mind was spinning made it hard to tell.
But my cock was harder than it had ever been in my life.
Right in front of me—my beautiful, loving wife—was getting fucked by another man. Her own son.
I didn’t care if it was a dream. I wanted to feel every second of it.
After a while Suyeon’s voice broke through again, trembling.
“Aaa… Jin-yeong… wait… slow down… haaah…”
“Mmm.”
The slapping stopped, but her moans spilled out louder than ever.
“Aaa… how is this… Jin-yeong… aaah…”
“Eep!”
She had reached her peak. Suyeon came faster than anyone I’d ever known—whether it was me or someone else, the moment something thick filled her or she was properly stimulated, she shattered.
“Aaa… too much… Jin-yeong, hold me… please…”
“Mom, I’m close too… aaah…”
“Mmm… together… come with me… deeper…!”
Thud, thud, thud, thud
The wet, obscene sounds returned, faster, harder.
Jin-yeong gave her one final powerful thrust and groaned.
“Aaa…”
“Aaa… Jin-yeong…”
The second round ended in a shared climax.
I couldn’t see it, but the sounds were more than enough to make my stomach twist and my cock pulse with frustration.
Jealousy. Rage. Envy. Lust. Love. None of them had a simple name.
“Huu… Jin-yeong, you really are something else. I can’t even think straight when you fill me up like this…”
“Hah… hah… I feel like I can’t think either. Your cock is gripping me so tight…”
“Today was so good. I hope that unexpected gift from you to Mom meant something to you.”
“Mom, every single thing we do makes me happy. I love you.”
“Mmm… my second husband… ahh.”
“Haha. I like being your second husband.”
“Now go to sleep, Jin-yeong. It’s too late. Dad’s alone downstairs, so I should go.”
“Mmm.”
I waited until Suyeon slipped out and I was certain she wouldn’t come back. Then I tiptoed down the stairs, climbed into bed, and lay there pretending to sleep.
A few minutes later I heard running water from the upstairs bathroom. The bedroom door finally opened.
Suyeon walked in wearing nothing but loose dolphin shorts and an off-shoulder sports bra. Her body was perfect—full, soft, and untouched by any extra fat. She’d probably used the shower to wash away every trace of their sex.
I wish there was still his cum inside her…
She stopped moving when she saw me lying with my back turned on the bed.
Pretending to sleep was hard. Every nerve was wide awake, but I stayed perfectly still.
Suyeon’s gaze felt like it was burning into the back of my head.
After a long moment she reached out and stroked my thigh—the last thing she ever expected me to hear.
“Hubby… I’m sorry. Just this one time… exactly once… even with you right here I… Jin-yeong was so amazing. I felt like I needed to reward him… but I only have you. I love you.”
I felt her lips brush my cheek in a soft kiss.
A short, powerful wave of emotion crashed through me.
This rule I’d forced her to keep had been broken by her own hand. Even now, with me sleeping ten meters away, she was sneaking off to fuck her son.
And I… I was still jealous, still turned on, still desperately in love with her.
Outside, the ocean waves kept crashing. The sound mixed with Suyeon’s distant breathing like a hallucination.
It was a summer night I would never forget.
