Mom's Forbidden Thrill: Fantasizing About Her Son's Cock
Seojin Kim stepped outside, and his adoptive mother, Harin Lee, let out a sigh as she watched him go. Recalling what had just happened, a pang of regret tugged at her heart. He seemed interested in girls, but his shy, introverted nature made it impossible for him to even talk to them properly, let alone date. As a mother, it left her feeling a bit wistful. Still, she took some comfort in knowing he wasn't completely disinterested in women.
"I should have taught him properly about girls..."
When Seojin was ten, he lost his parents in an accident and was on the verge of being sent to an orphanage. Harin, who had known him somewhat, stepped in and adopted him, raising him as her own. She was only twenty-six at the time—far too young, people said, urging her against it. But she couldn't bear to send the grieving boy away, so she took on the role of mother herself. She hadn't minded being called "auntie" back then, but lately, she'd started hoping he'd call her "mom." After ten years of "auntie," though, it felt awkward to bring it up now, so she just waited patiently.
Adopting him so suddenly had been tough at first—everything felt awkward and exhausting, and she often felt inadequate. She never regretted the decision itself, not then or now. But she did regret not fulfilling her role as a mother perfectly. She was deeply grateful he'd grown up straight and true, but there were so many things she should have taught him properly, and one big one was about women.
A few years after the adoption, Seojin hit puberty, and she knew he was sneaking peeks at porn. But as a mother, she had no idea how to handle it, so she just let it slide. In the end, that led to his passive personality. It felt like her failure to guide him was to blame, which weighed on her heart. But it was too late to teach him now, leaving her with nothing but deepening worries.
"And I've got my own issues to deal with..."
So focused on raising him from such a young age, she'd never had a proper romance. After adopting Seojin, she had no time for men at all. Even before, she'd never been interested in the opposite sex, which made dealing with him even harder. Things were smooth sailing now, but she still sometimes couldn't read his mind.
"Maybe it's time I found someone..."
Now in her mid-thirties, she was at an age where marriage might be considered a bit late. Raising Seojin had kept her from paying any attention to men, but as he grew into a full adult, her own interest was stirring—like a belated puberty. She wondered if Seojin would approve, but her curiosity about the opposite sex was growing stronger by the day.
"Come to think of it... are all guys that big?"
The image of Seojin's dick from when she'd opened his door earlier flashed in her mind. She gauged its size roughly with her hand.
"Am I losing it...? No matter what, it's my son's... I mean, it was big, though..."
She'd seen plenty of cocks in porn, but this was the first real one she'd laid eyes on—and it being her son's made her feelings all tangled up. Still, the sight wouldn't leave her head.
"It's so different from when he was little..."
Up until he was twelve, she'd helped him change clothes and seen it then. This was a world apart, a full-grown man's tool that filled her with maternal relief—he'd become a proper man.
"Way bigger than the guys in porn..."
It looked at least 1.5 to 2 times the size of the men in the videos she watched, which was why it kept popping into her thoughts.
"I'm crazy... he's my son, for God's sake."
Her cheeks flushed slightly, her body heating up without her realizing it. Feeling a twinge of self-loathing for thinking of her son's dick this way, she couldn't shake it—her first glimpse of an adult man's cock.
"I should just clean his room."
She wasn't really perving on her son, she told herself. Cleaning would distract her. She hadn't cleaned his room since middle school; he handled it himself in high school. But earlier, it had looked like it needed it. To push away those indecent thoughts, she headed into his room.
A different scent hit her than what she'd smelled before.
"Smells like night-blooming flowers..."
Recognizing the musky aroma of male arousal, her cheeks burned. No weird thoughts, she scolded herself, starting the cleaning. She gathered scattered clothes for laundry—the floor was spotless, no dust.
"He keeps it cleaner than I thought."
It wasn't too messy, so she just planned to empty the trash. Heading to the bin...
"Wh-what the...?"
The trash can was stuffed with used tissues, reeking even stronger than the room's ambient scent.
"Gulp...♥"
Knowing exactly what they'd been used for, she tremblingly picked up what looked like the most recent one. Peeling it open, fresh, sticky semen clung to it, not fully dried.
"D-do guys normally cum this much?"
Pulling it apart released a thick glob of cum, far more viscous and abundant than she'd imagined from porn or common knowledge. She was stunned.
"Haa♥... haa♥... What am I even thinking?!"
She'd almost leaned in to sniff it. Barely regaining her senses, she hurriedly emptied the bin.
"Right, this just proves he's healthy... that's all."
Like hypnotizing herself, she rationalized it away, finishing the cleaning and leaving his room as her body grew warmer. Unintentionally confirming his virility had burned the morning's sight even deeper into her mind.
"Ugh... it'll be fine, right?"
With her body so aroused, there was only one way to cool off—and Seojin was out, giving her plenty of time. Blessed with the ultimate masturbation fuel, she headed to her room intending to relieve herself. If she didn't, she'd be a horny mess when he returned. Sure, masturbating to her son's dick and cum scent was utterly depraved, but her mind was flooded with it—nothing else would do.
"It's just a fantasy, nothing more♥."
Even she knew it was sinful, but nothing else could quench this fire. She slipped into her room, grabbed her secret rotor for nighttime sessions, and lay on the bed.
Vrrrreeeeem
"Ngh♥"
Her pussy was already soaked—no foreplay needed. Pressing the rotor against it over her panties, she started moaning lewdly, sounds she could never let her son hear.
"Haaang♥... hngh♥... dick♥... huge... hngh♥... dick♥"
Closing her eyes sharpened the image of her son's cock—its shape, size, scent—making her body burn hotter. Knowing she shouldn't only fueled the taboo thrill. Soon, she lost herself in pleasure, masturbating furiously.
"Haaaang♥"
Oblivious that she'd left the door slightly ajar...
.........
"I'm home."
Back from a walk to adapt to this body and test his Golden Sun Sense, Seojin entered the house.
Hm? This feeling...
He hadn't grasped it fully at first, but now his senses clearly told him: there was a fuckable bitch in the house, ripe for conquest.
"Haaang♥... hngh♥"
No need for senses—the moans guided him. He crept to the door and realized it was his adoptive mom's room.
No way, in broad daylight?!
Peeking through the cracked door, there she was: lost in masturbation, moaning sluttily. So engrossed she hadn't heard the door creak, rotor buzzing against her panty-clad pussy—a lewd bitch in heat.
His cock hardened involuntarily; this aroused him more than the naked woman in the park earlier.
But not yet, huh...
His sense warned him: pounce now, and it wouldn't work. A bit disappointing, but it wouldn't be long. Smiling, he watched her a moment longer before slipping away to his room, suppressing the urge to ravage her until she noticed.
The horny mom, oblivious that her son was watching from the door, kept masturbating in depraved bliss...
