Full Course with a Married Woman (5): A Mother Who Seduces Her Son
There are plenty of women in the world who seduce men, but no mother seduces her son. A mother tempting the child born after breaking all human taboos couldn't emerge from any normal mindset. Let alone one who believes a man she's meeting for the first time is her son and seduces him. It was utterly impossible.
...Except for the woman right in front of me now.
"Son. Come here for a sec?"
Shedding her stern mother's demeanor, she spoke softly. Her face beamed with affection as she gazed at me, smiling gently as if I were truly her child.
When I approached at her words, she took my hand carefully and led me to the bed. As I lay down, pushed by her touch, she lay beside me and said,
"You heard Dad's coming home late tonight, right? Yeah?"
Her warm eyes overflowed with maternal love. She was playing the role of a doting mother to perfection. The only reason I knew it was an act—
"While Dad's away, our son has to take his place. You know that, right? Yeah?"
—was that her warm, gentle gaze wasn't on my face. It was fixed on my lower half.
Her hand slipped into my embrace. Her words were all "Come to Mommy's side, okay? Good boy?" but the way her fingers trailed over my skin felt like pure seduction, like some temptress at work.
Wait, but how old did she think I was in her head? If she really saw me as the same age as her kid, this kind of thing would be impossible from the start...
"Hold on. No phones allowed."
As I reached for my phone to check the app settings, she put on a stern face and blocked my hand.
...Fine, if she was going to play it like this, I'd have no choice but to go along.
"Why not? I wanna use my phone."
I whined like a spoiled kid who asks his parents about everything. Her expression softened instantly, and she met my eyes with a kind smile, her warm breath brushing my face.
"Our son's still too young to know, but in the master bedroom, phones are off-limits. It's Mommy and Daddy's rule."
As if such a rule existed. I tilted my head in pretend confusion.
"Why? Why do I have to follow Mommy and Daddy's rules? Tell Dad to follow them."
"You have to listen to Mommy all the way through. Want a spanking?"
She pinched my nose lightly, chuckled, and continued.
"You heard what Mommy said earlier, right? While Dad's away, the son has to take his place."
"Oh... yeah."
"Hmm... For our Geon-woo to take Dad's place, there's something we need to check first..."
She smiled like a mother brimming with love, as if doting on her cute son, then whispered in my ear.
"Son. Have you ever masturbated?"
***
We were under the same blanket. She'd said something like, "It might be embarrassing to lie next to Mommy, so let's cover up with the blanket," and pulled it up—but no normal mother would need that with her son. She'd covered us so she could strip naked without her "son" noticing.
I calmly answered as she rustled around under the covers, shedding her shower robe bit by bit. Hearing my response, she let out a flustered voice.
"So... you've masturbated?"
"Yeah."
"...Good boy, such a good boy. Our son did it all on his own without Mommy teaching him."
What the hell? Her words said one thing, but that disappointed look on her face...
Did she plan to "teach" me how to jerk off if I'd said no? ...Even with the MC OP settings, her thoughts were terrifying.

If I thought about that screen from earlier, but with "husband" replaced by "son," her actions made a twisted kind of sense...
"How did you do it? Did you stroke it with your hand? Did white pee come out? Yeah, white pee. Know what that is? Want Mommy to tell you?"
Her tone was so desperate, almost frantic, as she grilled me on whether I could ejaculate. It was downright scary. Her brain was probably running the logic: son can ejaculate → son can impregnate Mommy...
"Uh... not really sure."
Her intensity made it hard to pick an answer. Say I hadn't, and her warm hand on my stomach (she was humming "Mommy's hands are gentle hands," drawing little circles—but they were sliding lower, so definitely not that song) would grab my dick and start stroking. Say I had, and she'd go, "Then you can take Dad's place," and pounce.
At my vague reply, she hesitated for a moment.
"...Son. No noises, okay?"
After a brief pause, she seemed to make up her mind and whispered again. Her soft hand reached my lower half. I twitched, and she giggled cutely, pressing right up against me.
"If you don't know, Mommy'll teach you. You know what Mommy's holding, right?"
"P-Pee-pee."
Embarrassing name for a grown man, but the mood called for it, so I played along. She tickled the base slowly.
"Right, pee-pee. But men's pee-pees are also called cocks. Know the difference?"
"No idea."
"A pee-pee that can ejaculate is called a cock. That's why Daddy has a cock."
Her hand formed a ring around the base and gripped my whole shaft. I felt her soft fingertips caress the head as her voice continued.
"We don't know yet if our son's pee-pee is a cock, so Mommy'll check."
With that, her hand pumped up and down. Gentle yet rough, rubbing her palm against me. Her slender fingers tapped the tip, utterly focused on making me cum.
But even while jerking me off, she wanted to keep up the motherly act.
"Pee in Mommy's hand. Pee the white pee. That's it, good boy."
I flashed her a mischievous grin.
"Mommy. You do this for Daddy too?"
Her face fell in panic. She glanced around embarrassed, then carefully replied,
"No, not for Daddy."
She milked my cock like a udder, squeezing from pinky to index. Her thumb teased the head to urge me on. Face flushed red, but she did it all.
Something boiled up inside me at the sight. Thick spurts erupted, soaking her delicate hand white.
"Good boy, so good. Our son's pee-pee isn't a pee-pee—it's a cock. Now you're a real man."
Even after I finished, she stroked for another 30 seconds, then held the globby cum in front of her face. She sniffed it like savoring a male's scent, then tilted her head to let it drip into her mouth. She licked her lips seductively and swallowed with a gulp. Climbing atop me, she looked down and said,
"Now, Mommy'll teach you what men do."
Her expression saw not a son, but a stud.
***
She desperately justified her actions. Even now, bodies entwined under the blanket with her "son."
"While Dad's away, the son takes his place—that's the rule. Yeah, a house needs at least one man."
She rode me, hips grinding up and down, mouth running nonstop.
"Our Geon-woo has a cock, so he's a man—a stud. You learned in sex ed? Female and male. So Geon-woo has to do Dad's job. Mommy's the female, Geon-woo's the male. Got it? It's not weird at all, so don't think strange, okay?"
She stopped her hips and hugged me tight, bodies pressed close. As pleasure numbed me into shallow breaths, her excited sighs tickled my ear. A melting moan heavy with lust revealed her soaked desire.
She caught her breath. Once calmed, she spoke like confirming before a final rite.
"Know what Dad does? Lots of things, but one is getting his wife—Mommy—pregnant."
Still hugging tight, she wiggled her hips to tease me. The slick walls of a married woman's pussy yielded smoothly. Her voice tickled my ear.
"But Mommy said Dad's late tonight. So Geon-woo has to fill in. Yeah. Our son has to impregnate Mommy instead of Dad. Got it?"
The scenario was strictly "the only man around for her frustrated impregnation craving is her son." She knew her actions were abnormal. But ruled by lust, she justified it relentlessly to fool her "son."
"It's not weird, so no misunderstanding. And don't tell anyone. It's Mommy and Geon-woo's secret. Okay? Got it?"
Craving her son's seed without a thought for condoms, she was chillingly greedy and lewd. Well, with only "impregnation impulse" not plain "lust," even if she remembered condoms midway, she wouldn't mention them.
Anyway, she wheedled me to seduce her son, making her fabricated excuse feel real.
"Say today's our secret, and Mommy'll keep doing it. Yeah? Felt good for Geon-woo? Putting your cock in Mommy, taking Dad's place? Nod if you want more. Good... good boy...?"
I considered teasing her like at the eel restaurant, but held back. Her captivating eyes held a dangerous glint—if I played dumb with "Huh? Not feeling it. Let's stop," she'd flip out and do something crazy.
I nodded casually. Thinking her excuse worked, she continued.
"That white pee from Geon-woo's cock? That's semen. When it goes in Mommy's pussy... Ah, know what a pussy is? Under a woman's—"
"Enough."
As she veered into full sex ed, I blocked her lips with my finger. In her head, I was her son—she could see me as a rude kid blocking his mom. But addicted to ecstasy, she didn't care; she sucked my finger right in.
Slurp, smack—gluck, squelch—Devouring my finger up top, my cock below. She'd seen her son as just a nursing babe; now she craved his finger and milked his dick for every drop.
The lewd sight before me, pleasure surging from my hips. Soon, something stirred deep inside. Without a word from me, she sensed it and locked her legs around my waist. Determined not to spill a single drop of her son's semen.
Impregnation desire. Just one button press, and it gripped her mind, turning a chaste wife into a cum-hungry slut in vulgar poses. My heart raced at the thought.
"Come here. Time for milk?"
Like calling a babe to nurse, she spread her arms, legs still wrapped around me. No memory of actually nursing from her, but hey, jackpot—I dove into her embrace. Buried between her tits, I unloaded inside her as she cooed sweetly.
"Yeah... Let's keep doing this forever... Mommy gives milk from her breasts, Geon-woo gives milk from his cock. Until the baby comes... Every day..."
Her thick feminine scent enveloped me. Her soft breasts warmed my heart to melt. Hearing her tickle my soul from between them, my spent cock hardened inside her again.
Feeling it, she hugged me tight, rocking like in rapture.
"Our son already hard again? Gonna cum in Mommy once more? Amazing. Dad finishes after one go. Guess our son's got a real cock, not like Dad's pee-pee."
Her seductive whispers filled my ear.
"This time, you do it? Mommy'll help."
She flipped us over with a grunt, putting me on top.
***
"In and out, in and out. Good boy, our son. Already learned to pound Mommy's pussy deep?"
Shameless now, she guided me slowly, teaching "how to conquer her."
"Yeah, like that—a bit upward. Poke it deep. Good, so good. Way better than Dad, our Geon-woo. At this rate, Mommy'll only want Geon-woo even after getting pregnant. No more Dad."
Every time I satisfied the "pregnancy" obsession filling her head, she purred in satisfaction.
"Cumming again? Thanks for filling Mommy's pussy. Mommy'll try hard to have your baby. Yeah, not Dad's—your baby..."
A mother denying her husband before her son. How lewd. Even when I pushed, saying "Then no more with Dad," she replied demurely.
"Yeah, got it. Only with Geon-woo from now on. Not Dad. You're way better. A much better man."
As if the "husband" in her mind was drowned in the thick white semen from fucking her son. Her heart's place for her husband turned all white.
How many times did I cum? Skipping meals, she panted in the marital bed she'd surrendered to me. Declaring herself her son's bitch, even doggy-style drew not a mother's dignity but a female's moans.
"Yeah, pound me from behind like that. The position I told Dad never to do. Sons can do whatever..."
I lay beside her collapsed form. No thought of cleanup. Just satisfaction from dumping everything inside her, I drifted to sleep.
"Thanks for cumming in Mommy's pussy. Mommy... will definitely get pregnant from our son's cock... Thanks for giving me a baby, my baby..."
Finally, her voice—a mix of seductive lure and maternal lullaby. Probably both. She was mother and bitch now.
