Mom Forced by Dad to Be Son’s Sexual Desire Processing Tool

Chapter 1: The Beginning – The Family’s Collapse Contract

My name is Kai, 19 years old, a freshman in college. The day I came home for summer vacation, the atmosphere in the house felt strangely twisted.

Dad was sitting on the living room sofa smoking, his face dark and grim. Mom — Lin Meiling, 38 years old — still had a smoking-hot body like a woman in her early 30s. Her massive H-cup breasts strained against her tight home clothes, her waist was slim, and her ass was round and juicy enough to make anyone want to bite it. She stood in front of Dad with her head lowered, hands trembling slightly.

“From today onward, you are your son’s exclusive sexual desire processing tool,” Dad said coldly, blowing out a puff of smoke. “No matter how late he comes home at night, you must serve his cock until he shoots every last drop. Understood?”

Mom looked up, her eyes red and swollen, her voice shaking: “Honey… have you gone crazy? I’m his mother…”

“Slap!” Dad smacked her hard across the face. “Shut up! Do you think I don’t know about you secretly cheating outside? Now you will obediently become your son’s cum dumpster, or I’ll send all those dirty videos of yours to our relatives and friends and ruin your reputation!”

Mom bit her lower lip, tears rolling down her cheeks, but finally lowered her head: “…I understand.”

Dad turned to me with a twisted, perverted smile: “Kai, starting tonight, your mom is your personal cum toilet. You can play with her however you want. She has no right to refuse.”

At that moment, my mind went blank, but my cock instantly got rock hard.

Chapter 2: The Development – The First Forbidden Training

That night at 10 p.m., after I finished showering and returned to my room, Mom was already kneeling beside my bed. She wore only a sheer black lace nightgown. Her huge breasts were practically bursting out of the neckline, and she was completely naked underneath, her plump pussy lips faintly visible.

She kept her head down, her voice barely a whisper: “Kai… Mom… is here to handle your sexual needs…”

My heart pounded wildly. I walked over, pulled down my pants, and my fully erect, thick cock sprang out right in front of her face. Mom stared at her son’s dick, her cheeks instantly flushing red, but she still reached out with trembling hands and gripped it.

“So… so big…” she murmured, then opened her red lips and took the head into her mouth.

Her blowjob skills were surprisingly skillful. Her tongue danced around the slit, and her throat contracted and sucked like a vacuum. I couldn’t hold back anymore. I grabbed her hair and started fucking her mouth like it was a pussy. Mom made wet, obscene “gluck gluck” sounds, tears and drool running down her face, yet she didn’t resist.

“Mom… your mouth sucks so well… you’re even sluttier than a prostitute…” I panted.

Dad pushed the door open at that moment, sat on the edge of the bed, and started recording with his phone. “That’s right. Meiling, treat your son’s cock like your favorite toy. Suck it hard!”

Encouraged by Dad’s order, Mom sucked even more eagerly, deepthroating until her nose pressed against my pubic bone, her throat visibly bulging. The pleasure made my scalp tingle. Before long, I roared and shot my first thick load straight down her throat. She choked and coughed, cum leaking from the corners of her mouth, but she still tried hard to swallow most of it.

“Not bad, shooting so much on the first day,” Dad nodded in satisfaction. “Keep going tonight until he’s fully satisfied.”

Chapter 3: The Turn – From Resistance to Total Slutty Corruption

In the following days, Mom was completely turned into the family’s “sexual desire processing tool.”

Dad set strict rules: Every morning after waking up, Mom had to give me a blowjob to handle my morning wood and swallow my cum as breakfast. Before bed at night, she had to take my cock inside her until I filled her womb or asshole. During the day, whenever I was home, she had to spread her legs or open her mouth anytime I wanted to relieve myself.

At first Mom would cry and resist, but Dad’s methods were brutally cruel — he would whip her massive breasts and ass with a leather belt right in front of me, forcing her to say increasingly filthy words.

“I am my son’s personal cum toilet… Please shoot your semen into Mommy’s slutty pussy…”  

“Mommy’s womb exists only for her son… Please creampie me as much as you want…”

Eventually, she started taking the initiative. One afternoon when I woke up from a nap, I found Mom riding on top of me, her plump, wet pussy swallowing my cock. Her huge tits bounced wildly with loud slapping sounds as she moaned like a bitch in heat: “Kai… Mommy’s pussy is so itchy… Fuck Mommy harder… Turn Mommy into a cum-craving bitch…”

Dad stood nearby, filming with a grin: “See? Meiling, you were born a whore. Now you can’t even live without your son’s cock.”

What was even more perverted was that Dad began joining the “family training.” He bought all kinds of extreme toys: cervical dilators, nipple piercing clamps, electric shock vibrators, and even spreaders that could stretch her pussy lips to the limit. He would make Mom get on all fours like a bitch while I fucked her from behind, and he would whip her back and ass, forcing her to scream the most depraved lines.

One night, Dad made an even crazier demand: “From today on, your mom’s asshole must always be ready for you too. And… I want you to train her into a double-hole cum dumpster that can take two cocks at the same time.”

Chapter 4: The Climax – Extreme Fallen Fantasy & Endless Cycle

During the last week of summer vacation, Dad completely let himself go wild.

He tied Mom to a custom-made sex frame in the middle of the living room, her legs pulled wide apart in an M-shape, exposing her pussy and asshole completely. Then he forced her to drink a bottle of transparent “demon lust potion” he bought from the dark web.

After the drug took effect, Mom’s body began to change dramatically: her nipples became hypersensitive and started spraying milk; her pussy contracted like it had countless tiny mouths sucking; her asshole became incredibly soft and could easily swallow my entire thick cock. The most insane part was that her cervix could slightly open, allowing me to push my cockhead directly into her womb and cum right against the fetus.

I went completely feral.

I took turns fucking her front and back holes, sometimes even double-penetrating her (using a double-headed dildo to assist). I fucked her until she lost control of her bladder, sprayed milk everywhere, rolled her eyes back, and drooled uncontrollably. Mom was totally broken. The only words left in her mouth were:

“I am my son’s sexual desire processing tool… Please shoot your cum into Mommy’s body anytime… Mommy only wants to be fucked senseless by her son…”

Dad laughed maniacally on the side: “Perfect. From now on, your mom is our family’s exclusive breeding bitch. When you come home from college next time, she’ll be even better prepared… maybe even pregnant with your child so you can keep fucking a pregnant mommy.”

On the final night, I pinned Mom on the bed, my cock buried deep against her swollen cervix, and asked while pounding her: “Mom… do you still hate Dad for forcing you to be my cum dumpster?”

Mom’s eyes were glazed over, her tongue hanging out, her face covered in a blissful, slutty smile:

“No… Mommy now only wants to be fucked by her son… forever…”

Endless Epilogue

After school started, I went back to campus, but the “sexual desire processing contract” at home never ended. Every weekend I returned home, and Mom would always be kneeling at the entrance, wearing the sluttiest outfit, mouth or legs spread, waiting to process her son’s endless sexual needs.

Dad continued smiling and filming, occasionally joining in, turning Mom into a family sex slave with no dignity left — only holes and a womb for breeding.

This family had completely degenerated into an endless cycle of lust centered around Mom’s body.

And I… had already fallen completely in love with this feeling.

Pregnancy Training Arc (Extended Chapters)

Chapter 5: Discovery – The Forbidden Seed Planted in Mom’s Womb

Two months after summer vacation ended, I returned to school, but the contract continued uninterrupted. Every weekend when I came home, Mom would kneel at the door in nothing but nipple clamps and crotchless stockings, her huge breasts swaying as she greeted me: “Kai… Mommy’s slutty pussy and asshole are ready… How many loads do you want to shoot today?”

Dad sat on the sofa with the camera, grinning wickedly: “Keep fucking her. Turn her into a real family breeding bitch.”

However, this month Mom’s period was late. At first she thought it was stress, until one weekend while she was giving me a blowjob, she suddenly dry-heaved. Dad immediately dragged her to the bathroom, fingered her pussy to scoop out the cum I had previously shot inside her, and forced her to take a pregnancy test.

Two clear red lines.

Mom’s legs gave out and she collapsed to her knees, crying: “Honey… this is Kai’s child… I’m really pregnant with our son’s baby…”

Dad burst out laughing and slapped her already slightly swollen belly: “Excellent! This is the perfect ending. You’re no longer just your son’s cum processing tool — you’re now a pregnant cum dumpster carrying your son’s child! From today, the training upgrades. I want you to grow this belly big and round while still getting fucked to continuous orgasms by your son!”

I looked at Mom’s tear-stained face, which was already starting to flush with arousal, and my cock throbbed painfully hard.

Chapter 6: Pregnancy Training Begins – Milk Spraying & Womb Massage

From that day on, Mom’s daily life became a “pregnant sex slave training camp.”

Dad bought a bunch of extreme toys designed for pregnant women: belly-restraining belts, vacuum breast pumps, cervical dilators, and even low-frequency vibrators that could stimulate the fetus. He personally put all the devices on her, then called me into the room.

“Kai, from now on, even though your mom’s womb has your child, her holes are still your personal cum containers. You must give her ‘womb massages’ every day so the baby can hear Daddy’s cock pounding.”

On the first night, Mom was tied to the bed with her legs spread wide in an M-shape. Her pregnant belly was already visibly round like a plump meatball. She wore a transparent pregnant fetish outfit. Her nipples had begun leaking colostrum due to hormones, and her large pink areolas had become extremely sensitive.

I knelt between her legs, aimed my cock at her now even plumper and wetter pussy, and thrust all the way in. Mom screamed: “Ah— so deep— Kai’s cock is hitting the baby—!”

Dad used the breast pump to violently suck her massive tits while milk sprayed out like fountains, soaking the entire bedsheet. He commanded Mom: “Say it loud! What are you now?”

“I am… I am my son’s pregnant sexual desire processing tool… carrying my son’s child in my belly… yet still getting fucked by my son… Aaaah— I’m cumming—!”

I fucked her harder and harder, deliberately slamming against her cervix so her pregnant belly jiggled with every thrust. When Mom orgasmed, she sprayed a mixture of breast milk and pussy juice all over my stomach. Dad even inserted a thin womb rod beside my cock, gently stirring the amniotic fluid around the fetus while laughing: “Let the baby feel Daddy fucking Mommy too.”

From then on, every morning when I had morning wood, Mom had to use her pregnant belly to rub my cock until I came on her stomach. Before bed, I had to creampie her womb at least three times, mixing my semen with the amniotic fluid.

Chapter 7: Extreme Pregnant Heavy Play – Demonic Pregnant Belly & Public Training

By the fifth month of pregnancy, Mom’s belly was so big it looked like she was carrying twins. Dad said it still wasn’t enough and forced her to drink another “pregnancy demon potion” from the dark web. The drug supposedly made pregnant women extremely sensitive, increased milk production tenfold, and turned the womb into a cum-sucking machine.

After the drug kicked in, Mom’s body underwent insane demonic changes:

– Her breasts swelled to I-cup size and sprayed milk wildly at the slightest touch, like two fountains.  

– Magic pink patterns appeared on the surface of her pregnant belly; touching them would make her cum instantly.  

– Her pussy and asshole became incredibly soft and stretchy, able to take two thick cocks at once (Dad bought another dildo as thick as mine so I could double-penetrate her).  

– The most perverted part: her cervix could open slightly, allowing me to push my cockhead directly into her womb and cum right against the fetus.

I went completely wild.

One weekend, Dad tied Mom to a custom pregnant sex swing in the living room, her huge belly hanging downward, pussy and asshole fully exposed. He invited two “old friends” from the dark web to watch the show.

The two strangers watched me fuck Mom until she sprayed milk and squirt everywhere, their eyes turning red with lust. Dad generously said: “Today’s performance is free, but you can only watch, not touch. This is our family’s exclusive pregnant cum dumpster.”

Right in front of them, I pressed on Mom’s pregnant belly with my fist while violently pounding her womb. Mom was completely broken. Her tongue hung out, drooling, as she moaned sluttily: “Look, uncles… I got knocked up by my own son… I’m carrying my son’s baby… yet I’m still being fucked like a bitch by him… Please enjoy this filthy pregnant slut show…”

During her orgasm, she sprayed from three places at once — milk from her nipples, pussy juice, and urine — creating a lewd fountain show. The two men could only jerk off furiously on the side.

Chapter 8: The Eternal Pregnant Sex Slave Cycle – After Birth and the Next Round

By the ninth month, Mom’s belly was so enormous she could barely walk. Dad still insisted on “final pre-birth training.”

He rented a private delivery room next to the hospital, filled with sex equipment. The night before the due date, I pinned Mom on the delivery bed and fucked her still-open womb, shooting directly onto the baby’s head. Mom screamed in orgasm as amniotic fluid mixed with cum poured out.

On the day of delivery, the doctor was paid off by Dad. I held Mom’s hand in the delivery room while my cock was buried inside her still-recovering pussy, thrusting as I said: “Mom… the baby is coming out… but Mommy’s holes will always belong to your son…”

After the baby (a healthy boy) was born, Dad immediately announced: “One month after giving birth, we start the next round of training. This time I want you to get fucked while breastfeeding and get pregnant with the second child.”

Mom lay in the hospital bed, one nipple being sucked by the baby, the other being sucked by me, while my cock was already inside her recovering pussy. Her eyes were vacant but filled with a blissful, slutty smile. She whispered hoarsely:

“Kai… Mommy will always be your sexual desire processing tool… no matter how many babies I carry… no matter how big my belly gets… Mommy’s womb, holes, and tits… are all for you to use…”

Dad filmed everything with a demonic grin: “This is our family’s true happiness. The next baby might be a girl… then the whole family can play together.”

Endless Epilogue

This family had completely fallen into a lust empire centered around Mom’s pregnant belly. Every weekend when I came home, I would see Mom with an ever-growing belly, kneeling on the floor to welcome me, treating breast milk and cum as her daily “nutrition.”

And Dad’s next words were always the same:

“Keep fucking her. Turn her into a pregnant cum dumpster who is forever carrying your children… until her womb is completely ruined.”
