The Diary That Changed Everything
I had always wondered when my wife and son began their intimate encounters, a question that had been burning inside me for months. The only way to uncover the truth was to examine their phones—my wife’s or my son’s. It took surprisingly little time to find the answer.
On my son’s hidden folder, every detail was meticulously recorded: conversations between my wife and son, a collection of photos and videos they had taken together, and even diary entries written in a journal-like format. Despite the demands of his senior year in high school, my son had been documenting every moment with extraordinary precision.
I transferred all of this information to my own phone. What followed was the beginning of my secret life—watching my wife and son make love, and finally initiating my own voyeuristic observations.
The voluminous evidence I discovered on my son’s phone traced back to the very first time I suggested my wife sleep with another man. Even the recent nights I had come home early were fully captured in those recordings.
Just a few days after my wife and son first made love, I slipped into my wife’s bedroom while she was fast asleep, turned on the computer, and began reading the copied diary entry by entry.
Kim Jin-yeong’s Diary – Beginning
My name is Kim Jin-yeong. I am a healthy twenty-year-old university freshman who spent a perfectly ordinary middle and high school life.
A few days ago, in the middle of the night, I woke up because I needed to use the bathroom. From the master bedroom came my mother’s sensual moans.
There they were—naked—my mother and my father, making love. My mother’s body was breathtakingly beautiful, even to me.
“A… ah… honey, I love you.”
“Su-yeon, shh… Jin-yeong might wake up.”
“At this hour, no matter how much you carry our son, he won’t stir.”
“Really? Su-yeon’s pussy tastes so delicious. It’s so tight and juicy.”
“Ah… Dong-yeon… how am I? Does it taste good? Ah… ah…”
“If you keep talking, I’ll keep going…”
‘Squelch… squelch…’
“A… honey, it feels too good… please go deeper…”
“Got it… thrust hard!”
“Ahhk… honey…”
My mother wrapped her arms around my father’s neck and pulled him closer, holding him in place as he pounded her. Suddenly his thrusts grew even more violent, and his thick cock slammed in and out of her pussy at lightning speed.
“A… huuuuuck…”
“Honey, it’s coming… hngh…”
“Dong-yeon, fill my pussy with your cum… I’m your woman… I love you.”
“En… honey, I love you…”
“Aaaahhhhhhhhh….”
My mother came, her whole body shuddering in ecstasy.
At the same time, without realizing it, my hand had slipped inside my panties, stroking my rock-hard cock to completion.
Overwhelmed by the unspeakable pleasure, I reached climax and shot my load. I quietly returned to my room so my mother wouldn’t wake up.
Luckily, after coming, I didn’t need to pee anymore.
That important night passed peacefully.
Seeing my parents always taking care of each other gave me the sense of security I needed. Because of that, I passed through puberty without any major incidents.
Until I prepared for college entrance exams, I only had a casual interest in sex. My first real sexual fantasy began the moment I became a university student.
My habit of masturbating started right after that night and the same time my love for my mother began to grow.
“Mr. Jin-yeong~. It’s time to wake up. Let’s get up. Breakfast is ready.”
“Mm… just five more minutes… zzz…”
“You can’t. If you don’t get up now, you’ll be late. Wake up right now.”
“Awww… then give me a kiss on the cheek…”
Whenever I threw a tantrum, my mother would kiss my cheek with a soft “smack.”
“Ugh… you’re already so grown up, you little brat.”
“Yeah! Mom’s kiss made me feel so light and energetic!”
Every day began with my mother’s kiss on the cheek.
At some point, I realized I loved her cheek kisses more than anything. Her soft lips felt exactly like soft, sweet rice cake—smooth and satisfying.
Years later, I discovered that her pussy was even more deliciously chewy than rice cake.
I sat at the table wearing only my underwear and ate the toast my mother had prepared.
Since I was little, I had always lived at home wearing only underwear. My parents never said a word about it.
During puberty they only told me I should start wearing clothes, but afterward they never once complained when I continued to do so.
I did it because at home I felt the most comfortable.
I commuted between ordinary school, home, and my tutoring lessons.
Sometimes, right after my last lesson, my mother would come to pick me up. From a distance she looked like a young woman in her twenties—petite and fresh-faced.
Just looking at her made my cock twitch with excitement.
Our house was very busy because my father was a co-CEO of a trading company. He spent more time at work than at home, but thanks to him we lived comfortably.
My mother, a full-time housewife, devoted herself completely to making his life easier. Whenever I had a day off, she still found endless little tasks for me.
“Mr. Jin-yeong, you can’t just lie around in bed on the weekend. You drank so much last night—let’s eat breakfast and get up.”
“Hmm… Mom… I don’t have any energy left. Maybe I need a nutrient boost?”
“Sigh… fine. Come here… smack!”
My mother sat beside me, cupped my cheeks with both hands, and gave me a gentle kiss.
“Ah… this heavenly taste… I love being Mom’s son just for these moments.”
“Hurry up and go. I’ll cook your favorite bean sprout soup.”
“Yeah~”
I love my mother. As a woman…
I loved my mother, but I never once thought about having sex with her.
I simply enjoyed the sight of my parents’ loving relationship. Whether our family was special or not, those cheek kisses deepened our bond.
Even now that I’m a university student, I still let my mother kiss my cheeks every night.
“Jin-yeong, good night.”
“Yes, Dad.”
“For a while now, our handsome son—good night. Smack!”
“Mm… okay. Only tonight, though. Night…”
When I offered my right cheek, my father kissed it with his thick lips. As a child the scent had been sweet, but now it felt ordinary.
By contrast, my mother’s cheek kisses were pure honey—her lips incredibly soft and warm.
Her cheek kisses made me feel like I was floating on air.
My mother had given me permission for sex because the cheek kisses had crossed a certain line and served as foreplay.
Once I was comfortable, she told me:
“Mom loves Jin-yeong too, but we never imagined the two of you would have sex. Still, the feelings I had for you were so much deeper than a mother’s love. After all, you’re such a handsome boy… and you look just like Dad when he was young. I always secretly loved him. Sometimes when we’re together I even feel like Dad’s body is covering yours.”
“Of course that’s true. Who’s my son? Sex with my own son is definitely better than with some stranger…”
“She can’t stop talking. It’s true. She even has a second husband and loves him a lot.”
Now, while my cock was buried deep inside her pussy, she still gave me cheek kisses every single day.
The cheek kisses were simply too good.
The night our relationship turned from sweet to intense happened just a few days ago, on a hot summer evening.
After playing basketball with my friends, I returned home drenched in sweat.
My mother was sitting neatly on the living-room sofa, staring at her phone. She wore a white strapless bra and pink dolphin shorts.
For a child, her appearance was unbearably arousing.
I stealthily stroked my thickening cock and then approached her.
“Mom, it’s so hot outside… if I take three steps I’ll be soaked. This house is the best!”
“My son is here~ I turned on the air conditioner. It’s cool now. Dinner time soon. Today I made tray-jjajangmyeon—the one you like. Your dad is busy at work so he’ll be late. Eat without him.”
“Oh, tray-jjajangmyeon! If one of us dies, it still tastes amazing! Let’s eat together, Mom.”
“Okay. I’ll order it now. Go take a cool shower, Mr. Jin-yeong.”
“Yes, I’ll leave my clothes in front of the bathroom. Mom.”
“Alright.”
Normally, after showering, I would open the bathroom door and find my panties right there. But that day was different.
I half-opened the door and only poked my head out to look for my panties.
“Mom’s panties aren’t here.”
“I left them right in front. Look carefully.”
I opened the door a little wider and, because the floor was slippery, I slipped and the door swung open wide, leaving me completely naked.
“Oops! Mom!”
“Crash!”
She looked over and jumped. “Mommy, are you okay? What happened?”
Concerned, she hurried toward me.
“Ah… the floor was slippery. I almost fell.”
Looking up at her in my awkward position, I saw her worried face.
“Here, your panties… did I lose them? The tile floor has been slick for days, and our son almost got hurt… Mommy was so scared. Lucky you didn’t.”
I stood up and reached for the panties she handed me, but the sudden shock made me forget I was naked.
Standing, I was already a full head taller than my mother.
Her eyes widened as she stared at my cock.
“Oh my, Jin-yeong… you’re naked. Put your panties on right now.”
“Huh? Mom, I didn’t realize I was naked. I must have forgotten because I was surprised.”
I quickly turned around and put my panties on.
My mother pretended not to look and stood beside me, stealing glances at my cock.
