Sex Education from Mom
"Bathing with you is a first for me, Mom."
"W-well, we used to bathe together when you were little."
"Did we? I don't really remember."
"That's because you were little back then..."

I was in the middle of my bath when my son walked in. It had never happened before, and the shock of it left me so flustered that the words wouldn't come out right. Doing my best not to look at him, I sank into the bathtub and kept my eyes fixed on the wall. He's my son. I can't be thinking anything strange! Yet the moment my guard slipped even a little, my gaze drifted toward him all on its own.
He was taller than most men and still a little lean, but I could see he'd put on more muscle than he'd had a week ago. He's changed so much since he fell down those stairs... According to the doctor, losing his memory could change his personality along with it. Even if it had, he was still my beloved son, and that would never change. It was just that the memory loss seemed to be total—he hadn't recognized me, his own mother, or even his younger sister.
It isn't that I dislike the son I have now... But his gaze was so different from before. He used to be unable to hold a woman's eyes for even a second, and he dreaded going outside at all. With women forever staring at him and striking up conversations, he'd found it all unbearably overwhelming. Yet today he had gone out for a walk of his own accord. With Hyeon-jeong, of all people...
She was at least a woman who said her hellos, but even so, he had refused to be seen with her. Whenever she dropped by our house, he would scurry off to his room to hide. Males were simply made that way, so there was nothing to be done, but Hyeon-jeong had been quietly hurt all the same—he used to play with her when they were children. Now, though, everything was completely different.
"Bathing with you is nice, Mom~"
"Y-yes, Mommy likes it too♥"
There he was, bathing naked beside his mother without a trace of embarrassment. He's looking at me. My own son is looking at my body... haah♥ It was not my imagination. For the past week I had felt my son's gaze settling on my chest, on my ass. Especially when Jihye wore her Yukyugwon uniform, he stared blatantly at her chest and ass—and his crotch responded. It only twitched against the fabric, but the look in his eyes was unmistakably that of a man seeing a female as a female.
My son is awakening to sex♥ That he would aim such a look at his own family was a little unexpected, but for him to take an interest in a female at all was something tremendously worth celebrating! As his mother, I needed to educate him so that interest would grow even stronger. So the time has come to put what I learned at Yukyugwon to use♥
I was a graduate of Yukyugwon myself. Sadly, I had never come to have a master of my own, but with such precious children as these, I had no regrets.
"Then come on in here and wash with me."
"Yes, Mom."
Unlike most men, he was perfectly confident even in front of a female. Was it because I was his mother? When he finished washing and rose to his feet, he turned his body toward me. N-no, it can't be♥ My son's cock, half-erect, was pointing straight at me—a cock that had to be more than eight inches long at the very least. It was nothing like the small, precious thing I remembered from his childhood. They never taught us about anything like this♥ We had been taught that the average man, when erect, measured around four inches, and even the biggest rarely reached six. But my son's cock left that common knowledge far behind.
"I'll head in then."
"Y-yes. Come on in♥"
This was my first bath with my fully grown son, and with the two of us in the tub together, it felt a little cramped.
"Sitting face to face is kind of awkward."
"If it's uncomfortable, should Mommy get out?"
My heart was pounding fast enough to burst with how happy I was, but if my son was uncomfortable, I couldn't very well make him stay.
"No, it's fine. We just need to change the position a little... like this."
"S-son?!"
My son grabbed hold of me and pulled me in. His strength startled me—but only for a moment. Before I knew it, I was sitting perched on top of him, our bodies pressed together. M-my butt is touching it♥♥ His cock was vivid against me, unmistakable. So big, so hot, so hard that my head began to spin with confusion.
"We're finally bathing together. You can't get out now."
"Th-that's right♥"
Ba-dump. Ba-dump. Ba-dump. Ba-dump.
As his mother, I was supposed to teach him, step by careful step, how to treat a female. Even after all this time, I remembered everything I had learned at Yukyugwon. I had to guide him so that his interest in females would only deepen. But all I can think about is cock♥ Right now my head was utterly full of my son and his cock. If that enormous length pressed against my ass were to slide inside my pussy... W-what kind of fantasy is that?!♥ Me, drowning in desire, throwing myself at my own son? Ethics aside, what if he lost his interest in females because of me? That would be nothing short of a national loss. Still, just feeling it a little couldn't hurt... mmm♥
Slide. Slide. Slide.
Pretending to adjust my position, I rubbed my ass against his cock. The feel of a cock against me for the first time in my life sent the female instinct inside me surging up wildly.
"Haah... haah... haah♥"
"Is the position uncomfortable?"
"H-huh? No, it's nothing. I'm just a little itchy, that's all♥"
Without meaning to, I had thrown myself into grinding against him. Wanting to stay like this a little longer, I fumbled out some excuse, and my son answered with a smile.
"I'll scratch it for you. It's around your butt, right?"
"Oh? R-really?"
"Yes. Is it here?"
Slide...
"Mmmmmh♥"
My son's hand came to rest on my bare ass. A man's hand, big and rough.
"Haah... haah... mmmh♥"
For a hand that was supposed to be scratching an itch, something about it felt a little off?
Knead. Knead. Knead. Knead.
My son was kneading my ass as though it were a toy to play with. His fingers dug into the flesh, gripping hard enough to sink in.
"Mmm... haah♥"
"Here?"
"Th-there, just a little more. Mmmh♥"
The depraved thrill of being excited by my own son's touch left me shuddering with rapture.
"Is that better?"
"Ah, yes. Thank you, son."
The moment his hand left me, reason came back, along with a pang of disappointment. What am I doing, feeling this? I had let myself get so carried away that I'd nearly seduced him. Nearly said it—won't you put this big cock inside Mommy's pussy?—and pounced. Calm down... Nothing could be worse than my son losing his interest in females over what I did today. So, smothering my desire not out of greed but for the sake of humanity itself, I spoke.
"Son... are you curious about a female's body?♥"
What is this? Is she asking me to fuck her? Mom was seducing me, subtle as anything. I had grabbed and kneaded her ass on purpose, and far from refusing, she had moaned like something in heat at the touch. She looked so lewd I wanted to take her on the spot, and my cock was already fully erect, ready to slide in at a moment's notice.
"It seems my son has taken an interest in females... so if there's anything you're curious about, Mommy will teach you everything♥"
Hearing her call herself a female did something to me. I knew the word woman didn't exist in this world, but still—it was hot. I could probably fuck her right now... That Mom was in heat for her own son wasn't exactly a secret she was keeping, either. She was still grinding her ass against my cock, savoring every second of it. It doesn't even matter to her that I'm her son? She really is a female, through and through.
Combine sexual frustration with male predominance, and you get a mother in heat for her own son. For all I knew, in this world that was simply common. Doesn't matter. I'd already decided my first time would be with Mom anyway. That was what I had spent the past week turning over in my head. She was my mother, and she wasn't my mother. At the same time, I'd always carried the urge to try it at least once with someone who was a mom. Maybe because I'd grown up an orphan? Back then, whenever I slept with an older married woman, I would make her call herself Mommy, and every time, a strange thrill would swallow me before I knew it.
"Yes... lately, when I look at females, my cock gets hard and I want to pounce on them."
"I see. I'm sorry Mommy didn't catch on sooner... mmm♥"
Playing ignorant. Playing innocent. Her voice brimming with what sounded like genuine curiosity, she went on.
"Every time I saw your chest and your ass, Mom, I wanted to grab them hard. I wanted to suck on them."
"A-at your own mother♥"
Mom looked a little shocked, but if it was the good kind of shock, it was working—her face flushed red with delight.
"I'm so happy... so this is what did it. Seeing Mommy. My precious son♥"
The moment she heard that I got aroused looking at her, she started swaying her ass without a shred of subtlety.
"Do you like Mommy's chest?"
"They look so big and soft. I want to knead them until I've had my fill."
"I see... haah♥"
She had only heard a few words from me, but I could feel Mom heating up fast.
"Then... do you want to touch them?"
"Is that okay?"
"Yes... if my son wants it, you can touch them anytime♥"
"Yes, Mom."
She gave her permission far too easily, taking my hand and guiding it slowly toward her chest.
Squeeze.
"Mmmmmh♥ Touch them however you like. Mmmh♥"
"Wow~ they're so soft."
Pretending it was my first time ever feeling a breast, I kneaded them, and a softness on an entirely different level spilled between my fingers. Well, it is my first time in this body. So technically, it is. Was I a virgin right now? Or not? I didn't know, but one thing was certain: Mom's chest was impossibly soft, and it felt incredible.
"Your chest is so squishy, Mom. I want to keep touching it forever."
"Whenever my son wants... mmm♥"
"Then can I touch them every day?"
"Of course... mmmh♥"
She handed her body over to her son far, far too easily. If anything, she seduced me like she had been waiting for this all along, and the sight of her lewdness made my cock harder and harder.
"This part of you has gotten just as hard as my cock, Mom."
"Y-you can't, not there♥ Mmmh♥"
Mom's nipples had gone stiff and taut. I pinched them between my fingers, and she seemed to love every second of it. Figures. A total masochist. In this world of male predominance, women called themselves females. There had been women who once tried to stand above men. They failed in the end, and for a long age since, their lives had been spent willingly sinking beneath men. Naturally, they couldn't help but turn out masochists. There was no other way to be. Let's find out just how much of one she is~
"Your nipples are getting bigger too, Mom."
Squeeze.
"Mmmh♥ H-harder is fine too♥"
I was already pinching her nipples hard enough to make her gasp, and still Mom wanted me to handle them even rougher. Seeing her like that made me even harder.
"Mom."
"Yes, my precious son♥"
Like a beast signaling its readiness to mate, I ground my cock against Mom's ass. She noticed, and for a moment she seemed lost in thought. Then, her voice trembling, she spoke.
"Did seeing Mommy really make your cock this hard?"
"Yes."
One word, carrying a firm and unshakable will.
"...I see. Then let's go to Mommy's room. Mommy will teach you all about females♥"
