The son, while in college, long wrote his mother fixation fantasies into his diary. After his mother accidentally discovered them, she did not scold him; instead, she responded in a gentle way. From secretly reading the diary, washing underwear, to actively leaving notes, the two gradually drew closer in tacit understanding and desire, and finally fulfilled each other's longing in the morning light.

That day, because I had a dinner gathering with classmates, I got home after midnight.

Afraid of waking Mom, I tried to keep my voice low when entering. Passing by her room, I gently pushed the half-closed door open a crack and found Mom wasn't asleep yet. She was sitting on the edge of the bed, reading a book intently under the bedside lamp. Her back was to the door, so she didn't notice me. I then quietly walked back to my own room.

After returning to the room, I habitually opened the locked secret cabinet.

"Ah..."

The things in the secret cabinet have been moved. I've always known the exact positions of my personal items since childhood. Now not only are some shifted, but it seems something is missing. I immediately checked — damn, the diary is gone.

That hidden cabinet was originally just a large wooden box where I kept my comics since childhood. After starting to access pornographic publications in junior high, I put a lock on it and made a pact with my mom: no peeking at my private collection. After high school, I accidentally saw my mother changing once, and from then on, I became obsessed with her body. Besides collecting incest novels, publications, discs, and my mom's sexy panties, I also wrote my sexual fantasies about her in my diary.

At first, I was quite angry and wanted to rush in to question her why she didn't keep her promise. But after calming down, I thought, since things had come to this, any reaction would only make the mother-son relationship more awkward. It would be better to pretend not to know and first observe her reaction.

I exited the room and then tiptoed to my mother's door. The light seeping through the crack indicated she was still reading, and likely reading my diary filled with confessions of sexual desire for my mother. I deliberately walked to the living room, opened and closed the main door, making a closing sound to signal my return. Just as the 'bang' sounded, the light in my mother's room suddenly went out. I became even more certain she had been peeking.

I deliberately went to her room, pushed the door open, and called her name softly.

"Mom..."

Mom pretended to be asleep and didn't respond. I thought to myself, that diary was probably still hidden under the quilt.

I calmly went back to my room to get a change of clothes and headed to the bathroom. Normally, a shower takes about twenty minutes. This time, I entered the bathroom but didn't shower immediately, wanting to give Mom time to put the diary back. I turned on the faucet, deliberately sang to indicate I was showering, but actually observed through the door crack.

A moment later, Mom really tiptoed out of the room, and what she was holding was my diary. After she came out of my room and returned to hers, I then left the bathroom. The first thing, of course, was to open the hidden cabinet—sure enough, it had already been put back, obviously in a hurry, and even the position was crooked.

I barely slept that night, my mind churning with thoughts. Clearly, Mom would also pretend nothing had happened. Although I didn't write in my mother-love diary every day, over the years it had become a thick volume. Especially after starting university, my obsession with Mom's mature body had reached an inescapable level. The diary was filled with how I secretly admired her full breasts, high buttocks, even peeped at her showering, changing clothes, and used her panties to masturbate.

I thought she might not have finished reading it yet, so I made an assumption: she might come to take it again when I'm not around. To confirm, I placed a hair on the spine of the diary book and locked the hidden cabinet again. If the hair wasn't there tomorrow, it meant she had touched it again. After arranging everything, I went to sleep. Before drifting off, I thought of another bold plan.

The next day was still as usual, Mom woke me up, nothing particularly unusual. The only difference was that she clearly hadn't slept all night, her eyes were bloodshot, and she kept yawning. After washing up, I left for school.

I am an only child; my father passed away when I was young. Mom took over Dad's garment business at twenty-five. Over the past decade or so, although she's had no shortage of suitors, she probably feared I wouldn't like it and never remarried. Being a manager long-term requires socializing, and she has always taken good care of her body, not looking at all like she's almost forty.

Perhaps because I grew up without sisters, I was especially dependent on my mother, but I never expected it to turn into a mother complex in the end.

Because of what happened yesterday, I couldn't focus on classes all day. In the afternoon, as usual, I called the company but was told she didn't come today. I thought she probably wanted to finish reading the diary she hadn't finished, so she didn't go to work.

When I came home in the evening, Mom was cooking.

"Mom, are you okay? Why didn’t you go to the company today?"

“Oh... Mom isn’t feeling too well today... so...” She seemed a bit unnatural.

After taking a shower, I couldn't wait to return to my room and open the hidden cabinet. Sure enough, the hair on the book spine had fallen off. Besides that, I noticed the collection of panties suddenly looked bright in color and were neatly folded into a stack. I picked them up and saw they had a slight residual warmth, as if they had just been taken out of the dryer.

Mom had obviously washed all those panties and, involuntarily following a woman's instinct, folded them neatly.

Could it be... she doesn't object to me using her panties for masturbation, and even seems to tacitly permit it?

I made up my mind and officially started the plan. That night, I wrote in my diary:

"Mom, I don’t know why, but I couldn’t focus in class today. I’ve been thinking about you the whole time. I’m going crazy. I want to possess you. Give yourself to me, Mom, I want you."

After writing it, put the hair on top as before, then lock it again.

The next day I deliberately got up earlier than Mom, letting my erect penis extend outside my underwear, then covering it with the sheet. After a while, Mom also got up. As usual, she would pull back my blanket to wake me. I closed my eyes pretending to sleep, hearing her footsteps approach, and sure enough, she pulled back the sheet in one motion. I closed my eyes imagining her expression at that moment.

Time passed second by second. Mom didn't move at all. After five minutes, I couldn't help but peek through a slit in my eyes. I found her staring blankly at my penis as if possessed. I deliberately turned over, and only then did she, as if waking from a deep dream, hurriedly cover it with the sheet.

“Xiao… Xiaojun… wake up.” Her voice was as tiny as a mosquito’s.

I pretended to wake up sleepily, turning over.

"Mom... good morning!"

“...It... should... be... time to get up.” She seemed not to have come to her senses yet.

I deliberately casually tried to lift the bedsheet, and she hurriedly turned her body back. I also felt that teasing my beloved mother like this was somewhat cruel, so I quickly put my clothes back on.

In the evening, I made an excuse to come back after 8 p.m., giving her some time to read the diary. When I returned, Mom was taking a shower. I hurried back to my room and opened the hidden cabinet. Sure enough, she had read the new confession. Additionally, I found that among those panties, there was a new style I had never seen before—an almost completely transparent black lace panty.

Not only did Mom tacitly allow it, she even provided sponsorship. After calming down and examining more carefully, I found a note tucked inside the diary's cover:

"Xiaojun, Mom is very conflicted. She hopes you see this note, yet she doesn’t want you to see it too early. Forgive Mom for not intentionally snooping on your diary. You have always refused to tell Mom whether you have a girlfriend. I originally wanted to find something like love letters or photos in your room, but I never expected... Mom was really frightened after reading your diary. I never expected that you always refused to have a girlfriend because you were secretly in love with Mom. Xiaojun, Mom isn’t some old-fashioned woman either. After keeping widowhood for so many years and never willing to remarry, besides wanting to care for you wholeheartedly, Mom actually has selfish motives too, wanting to keep you by my side forever. You wrote in your diary that you have an Oedipus complex, but how could Mom not also have a son complex? Mom’s heart is in such a mess. Xiaojun, if you see this letter, can you pretend not to know for the time being? Mom isn’t mentally prepared yet. Wishing you a sweet dream!"

PS: You like Mom’s underwear, and Mom is very happy. Don’t feel guilty, or think there’s something wrong with your psychology. I think men like women’s underwear. The ones you’ve collected are all old, so Mom is giving you a newer pair, worn only once; I hope you’ll like it.’

Seeing my mom's response, my excitement was indescribable.

When I left the room, Mom hadn't finished washing yet.

"Mom, is it done yet? I’m going to wash!"

"All right, all right!" She walked out of the bathroom. She was wearing only a thin shirt vest, and on her lower body only a white triangle panties. Following the water droplets that had not dried, almost her whole body became transparent. Her two nipples were clearly visible against the thin shirt, and because of the wetness at the roots of her thighs, the black pubic hair was also exposed through the triangle panties. This was the first time in my life I had seen someone dressed like this.

"Xiaojun... don’t look..."

Her face was flushed red, unsure if from shyness or the heat after bathing. Before entering the bathroom, I gave her a knowing smile. Mom had already started adjusting herself.

Entering the bathroom, I took off my clothes and was about to throw them into the laundry basket when I suddenly saw an apple-green lace triangle panty blatantly spread on top. The fabric in the middle had a puddle of milky-white sticky substance. I picked it up and smelled it—a faint fishy scent hit my nose. Mom had masturbated before I returned. That puddle was precisely her love juices. And she seemed to have deliberately left it out for me to see.

By now, I was completely certain that the change in our mother-son relationship was imminent.

After returning to the room, I took out my diary again, wanting to leave a few more words, only to find another note inserted between the pages:

"Xiaojun, Mom wants to borrow the videotape on the top shelf to take a look. Put it into the VCR, and I’ll come out to watch it at twelve o’clock tonight. But you must promise me, absolutely do not come out, and tomorrow morning you can take it back."

I glanced at the videotape on the top layer, its title in four large characters: 'Mother-Son Incest.' This was Mom's second step of adjustment, wanting to first understand what other people's mother-son incest situations were like.

At exactly twelve, the TV in the living room was turned on. Mom came out to look. I thought I should follow her wishes and not disturb her. But in the end I couldn’t resist and quietly opened the door to peek out — I only saw Mom not wearing a bra, wearing only that white triangle panties, leaning askew on the sofa, her two peaks raised as she stared intently at the screen.

After watching for a while, I went back to my room to sleep. I don't know how long I slept, but when I woke up, it was already past three, and the living room lights were off. I went to the bathroom and couldn't resist entering my mom's room.

She lay naked on the bed, her panties pulled down to her knees, the thick black pubic hair clinging to the root of her thighs as if drenched. This video had such an effect. Facing her jade-like body, I was already uncontrollably aroused, and down below, it stiffened up disobediently.

I stood by the bed thinking for a long time, watching her breasts rise and fall with each breath, and still couldn't resist reaching out to gently stroke her nipple.

"Mm……" She gave a soft moan, but did not wake up. I grew bolder and pressed my whole palm against her breast, kneading and fondling it up and down.

"Mm... mm..." She kept making soft, comfortable-sounding moans, still not opening her eyes. I thought it might still be too early, that her defenses had not fully opened up yet. But since she kept pretending, I simply decided to caress enough. So I became even less restrained, boldly fondling her: one hand kept kneading her breasts, while the other moved down to stroke her pubic hair.

"Mm... ah... mm... mm... ah..." Her voice grew more and more wanton, making me almost unable to restrain myself from lifting her legs and thrusting hard into her.

As I inserted my fingers into her vagina, she moaned wantonly as if talking in her sleep, but refused to open her eyes.

I changed my approach, pulling down her panties and parting her legs. The lighting was too dim to see clearly, so I simply turned on the main light. Her labia were slowly dripping with fluid. I climbed onto the bed and pressed my face against her vulva, using my tongue to part the slit, licking continuously.

"Ah... ah... ah... okay... okay..." She finally couldn't hold back and said "okay." So I became even more vigorous, using my tongue to flick and tease, while both hands reached up to tightly grip her breasts and knead them desperately.

Ten minutes later, her body suddenly went rigid, her hips lifting up and then slamming down hard — Mom had reached orgasm. Then her cunt kept trembling, and with each shudder a gush of lustful fluid spilled out; before long, the entire bedsheet was soaked.

She was satisfied, but a raging fire of desire still hadn't subsided in me. In the end, I had no choice but to kiss her on the lips and go back to my room to sleep.

I was awakened by some fondling. First, I checked my watch—7 a.m. Then I saw my mother sitting by the bed, one hand holding my penis.

"Xiaojun... no... don’t wake up... you... are still dreaming right now, understand? You are having a sweet dream."

I understood what she meant, so I closed my eyes again and let her do as she pleased. What a wonderful weekend morning.

I closed my eyes, deliberately making my breathing light and slow, pretending I was still deep in sleep. Mom's palm was warm, with a slight tremor, gently grasping my fully erect penis. Her fingertips first tentatively touched the glans, then slowly closed around it, moving up and down in a slow stroking motion.

"Mm……" I couldn't help a low moan escaping from my throat, yet still didn't dare to open my eyes.

Mom's breathing became ragged too. She sat on the edge of the bed, leaning slightly forward, her other hand quietly pulling down the edge of my underwear, exposing the entire shaft to the cool air. Her movements were gentle, yet carried a seriousness long suppressed. When the thin calluses on her palm rubbed against the sensitive coronal ridge, my hips involuntarily arched upward.

“Don’t move...” she said softly, her voice so gentle it was almost inaudible, “I’m still dreaming...”

I obediently stayed still. Her stroking gradually took on a rhythm, sometimes enveloping the entire length, sometimes just circling the glans with her fingertips. Clear prostatic fluid soon seeped out, which she spread, making faint wet sounds. The room held only our breathing and the occasional soft creak of the bed.

After who knows how long, she suddenly stopped. I felt the mattress sink as Mom climbed onto the bed. Her knees分开, straddling my thighs, but she didn't sit down immediately. First, her soft breasts pressed against my chest, the two already hardened nipples摩擦着我的皮肤 through her thin睡衣. Her face buried in the crook of my neck, her breath灼热.

“Xiaojun…” She called my name in a breathy voice, “Mom… is this really okay?”

I finally opened my eyes.

The moment our eyes met, Mom's cheeks flushed deeply, yet her eyes were a little moist. She did not avoid me, but instead pressed closer. I raised my hand, placed my palm on her back, and slowly slid it down along the groove of her spine until I grasped those full, elastic buttocks.

“I want you.” I answered directly. “I’ve wanted you for a long time.”

A flicker of complexity passed through Mom's eyes, then melted into soft compromise. She propped herself up and pulled her nightgown off her shoulders herself. Her mature, full breasts were completely exposed in the morning light, the areolas a darker shade, the nipples already fully erect from excitement. I reached out to cup one, my thumb gently brushing over the nipple, and she immediately let out a suppressed whimper.

“Gently... so sensitive...”

I sat up, pulled her into my arms, lowered my head, and took one nipple into my mouth. My tongue circled the areola, then gently sucked. Mom's fingers tangled in my hair, her body going soft as she leaned back. I kneaded her other breast with my hand, the flesh spilling between my fingers. Her lower body was completely wet, the white panties pressed against my thigh, leaving a warm, damp patch.

I slid my hand into her panties, my middle finger slipping along the wet, slippery slit. Inside was hot and tight, immediately gripping my finger. Mom's waist trembled, but she actively spread her legs wider.

"Already... so wet..." I said in a low voice.

"It’s all your fault... writing those things..." she said, glaring at me in embarrassment and annoyance, but with no intention of stopping me at all.

I pulled out my fingers and completely slid her panties down to the bend of her knees. She cooperatively lifted her hips, allowing me to fully remove that last layer of fabric. In the morning light, her thick pubic hair was damp with arousal, clinging to her slightly parted labia. I held my penis, the glans pressing against that soft, wet entrance, but didn't enter immediately.

"Look at me." I said.

Mom looked up. I slowly and firmly pushed forward. The glans parted the soft flesh walls, sinking in inch by inch. Her inside was tighter than imagined, layers of soft flesh wrapping around, hot and wet. When fully inside, both of us let out a simultaneous sigh of satisfaction.

"So full..." Mom's voice was choked with sobs, "Xiaojun... you're inside Mom..."

I started thrusting. At first, it was very slow, each time almost completely pulling out before plunging back in fully. Mom's legs wrapped around my waist, her heels pressing against my back, as if afraid I would leave. Her breasts swayed gently with the motion, her nipples rubbing against my chest. Soon, sticky wet sounds and soft thuds of flesh colliding filled the room.

"Hurry... can you hurry a little..." she finally spoke.

I held her waist, speeding up. Each thrust was deep and heavy, the glans repeatedly hitting the soft flesh at the deepest point. Mom's moans could no longer be suppressed, growing louder with each cry, her hands tightly gripping my shoulders. Her inner walls began to contract irregularly, as if climbing toward climax.

"It’s going in... Xiao Jun... Mom is about to..."

I thrust hard, burying the entire length to the deepest point. Mom's body suddenly arched, her inner walls convulsing violently as a stream of hot fluid gushed out, drenching the head of my cock. Her mouth hung open, but no sound came out, only faint gasps escaping. I didn't stop, continuing to pump, prolonging her climax. Only when she went limp and collapsed on the bed did I slow my movements.

I turned her over, making her kneel on the bed on all fours. When entering from behind again, the angle was deeper. I held her breast with one hand, while the other reached around to the front to rub her clitoris. Mom buried her face in the pillow but couldn't help raising her butt high to meet me.

“Shoot it inside….” She suddenly spoke, her voice muffled, “It’s okay… you can shoot inside Mom….”

This sentence seemed like the final permission. A numbness shot through my waist, and I buried myself deep inside, streams of semen shooting into her body. Mother's body trembled a few more times, her inner walls gently sucking me in, swallowing every drop.

After finishing, I didn't withdraw immediately. Instead, I lay down on my side in the connected position, holding her from behind. Semen mixed with her fluids slowly seeped out, wetting the area between our legs. Mom's hand covered mine, our fingers intertwining.

"What about... in the future?" she asked softly.

I rested my chin on her shoulder and kissed her earlobe.

“Just like this.” I said, “We have plenty of time.”

The morning light had fully entered the room. Outside, faint bird calls could be heard, and the air still carried the lingering scent of desire. Mom stirred slightly but showed no intention of separating. Her back pressed against my chest, warmth slowly transferring between us.

"Sleep a little longer," she said. "Today... I'm not going to work."

I tightened my arms, holding her tighter.

What a lovely Sunday morning.

And this morning had only just begun.

We lay there for a long time, still joined together. Semen mixed with her fluids slowly seeped out, making the area between our legs sticky. Mom's breathing gradually steadied, but her fingers never let go of my hand.

“It’s still inside...” she suddenly said softly, her voice hoarse from just having climaxed.

"Mm." I gently moved my waist, letting the half-soft penis rub inside her, "I don't want to come out."

Mom's inner walls immediately contracted slightly again. She buried her face in the pillow in shame, but the tips of her ears were bright red.

“Bad guy...”

I smiled, kissing the back of her neck from behind. My lips pressed against the fine beads of sweat, gradually moving down to her shoulder blades. Mom's body trembled sensitively, but she didn't pull away. My hand slid from her waist to her lower abdomen, palm against her soft skin, my middle finger following the wet, slippery crevice to find the already swollen little bud again, gently circling it.

"A... are you... wanting it again?" Her voice was tight.

"And you?" I asked back, my fingertip applying a little more force.

"Mm……" She did not deny it, but instead pushed her butt back, letting my fingers sink in deeper.

The half-soft phallus rose again inside her. I slowly thrust in and out a few times, bringing out more mucus and making faint wet sounds. Mom’s breathing became ragged again. She took the initiative to lift one leg, letting me go in deeper.

This time neither of us was in a hurry. I held her from behind, grinding slowly with each thrust. The glans reached the deepest point every time, but without forceful impact. Mother's hand reached back, gripping my waist, silently urging me on. The room was filled only with the soft sounds of flesh colliding and our suppressed breaths.

The sunlight outside the window had completely shone in. The air was mixed with the scent of semen and her body fragrance, ambiguous and warm.

“Change positions...” Mom suddenly said.

I withdrew. She turned over, lying on her back, legs naturally apart. The morning light fell on her mature body. Her full breasts were slightly flushed from the earlier intimacy, the nipples still moist. Below her abdomen was a mess; her thick pubic hair was matted into strands by fluids and semen. The slit in the middle was slightly open, and I could still see the white liquid I had just shot inside slowly seeping out.

I knelt between her legs, guided my erection into position again. This time, entry was exceptionally smooth. The moment it sank all the way in, Mom let out a long sigh and wrapped her arms around my neck.

"Look at me." she said.

I lowered my head to meet her gaze. Her eyes were very bright, holding shyness, desire, and a kind of relief as if she had finally let go of something. I began to thrust, gradually increasing the speed. Her legs wrapped around my waist, her heels pressed against my back, meeting each impact.

"So deep... Xiao Jun... so deep..."

I lowered my head and took one of her nipples into my mouth, sucking hard. Mom's back immediately arched, her inner walls contracting violently. I knew she was about to come again, so I sped up the movements of my hips, each thrust heavier than the last.

"Go on..." I said in her ear.

Mom's nails dug into my shoulders, her body suddenly tensing up. A stream of hot fluid gushed out, splashing onto my glans. Her mouth opened, letting out a silent scream, her inner walls spasming and tightening in waves. I didn't stop, continuing to thrust, prolonging her orgasm until she was almost trembling.

After she went limp, I slowed my pace. Panting, she reached out and touched my face.

"You haven’t yet..."

“Together.” I said.

I lifted her legs onto my shoulders, almost folding her in half. This angle allowed for extremely deep penetration. Mom's eyes instantly widened, but she didn't tell me to stop. I began my final sprint, each thrust going all the way in, my balls slapping against her buttocks, making crisp sounds.

“S-s-s… shoot it in….” She took the initiative to speak, “All of it… to Mom….”

This sentence completely shattered my reason. I growled, burying myself deep inside, streams of semen violently shooting into her deepest part. Mother's body trembled a few more times, her inner walls gently sucking me in, swallowing every drop.

After finishing, I didn't withdraw right away. Instead, I stayed in the connected position, lying on top of her. Both our hearts were beating fast, sweat gluing our skin together. Mom's fingers gently combed through my hair, as if comforting me, or perhaps confirming something.

"In the future, can it be like this every morning...?" I asked in a muffled voice.

Mom was silent for a few seconds, then chuckled lightly.

"It depends on your performance."

I looked up and saw the fine lines at the corners of her eyes filled with a smile. I lowered my head to kiss her; this time it wasn't a kiss of lust but a slow, deep, cherished kiss. Her tongue actively met mine, entwining.

By the end of the kissing, the half-hard penis was aroused again. Mom felt it, opened her eyes, and looked at me, with surprise in her gaze as well as indulgence.

"Really... full of energy."

"It’s all because of you."

She reached out and pushed at my chest: “Get up first. The sheets are ruined. Go take a shower.”

I reluctantly pulled out. A large amount of semen mixed with her fluids immediately gushed out, flowing down the crease of her buttocks. Mom blushed and clamped her legs together, but I grabbed her ankles and spread them apart.

“Don’t look...”

"I want to watch." I said seriously, "I shot it in."

Mom covered her face, but her body didn't really resist. I reached out, wiped a bit of the mixed fluid, spread it on her lower abdomen, then slowly upward to her breasts. Her breathing became ragged again.

“Xiaojun…”

“Once more.” I lowered my head and said into her ear, “In the bathroom.”

Mom didn't speak, just reached out and hugged my neck. I picked her up and carried her towards the bathroom. Her face was buried in my shoulder, her voice muffled:

"Today... I'm really not going anywhere."

"Mm."

"He doesn’t even answer the phone."

"Okay."

"Then... I'll keep you company."

I placed her on the bathroom sink and turned on the shower. Warm water fell, washing away the marks on our bodies but not the desire in our eyes. My already hard penis pressed against her entrance, and she guided me in with her hand.

The sound of water masked the sound of flesh colliding.

Mom's legs were wrapped around my waist, her back against the mirror, letting out sweet, syrupy moans each time she was thrust to the deepest point. The mirror reflected our intertwined bodies—a mature woman and a young man, forbidden yet real.

I don't know how long I did it. I only know the water went from hot to warm, then from warm to cool. Mom's voice went from suppressed to unrestrained, finally almost taking on a sob. She climaxed twice; by the third time, her whole body was so weak she could barely sit up, and she had to rely on me holding her.

When I finally came inside her, she gently bit my shoulder, leaving a faint but distinct teeth mark.

After turning off the water, neither of us rushed to go out. I held her and sat with her on the bathroom floor, letting her lean against me. Semen slowly flowed out again, staining a small patch of the floor. Mom伸出脚,用脚趾把它抹开,然后低低地笑了。

"Cleaning up in the future will be troublesome."

"I'll clean it up."

She turned her head to look at me, her gaze soft.

"Xiaojun, Mom really kept you by her side."

I tightened my arms, resting my chin on her damp hair.

"Mm. I'm never leaving again."

Outside the bathroom, the sun had already risen high. This weekend morning was stretched long and leisurely by us.

And the days to come would be even longer.
