As Harmonia raised her white short skirt to reveal what she was talking about to Ikumi,
Ikumi was faced with something impossible. What her eyes were seeing was not just an outline beneath the fabric—it was real. A reddish, thick appendage, almost like a leg, curved downward. Her gaze locked onto that "third leg," watching how it bent and disappeared into something unseen. Only a quarter of it was visible, yet it was already thicker than her arms or legs. Veins pulsed along its base, connected to her lower abdomen, bulging as if forced to expand. Its skin had a raw, reddish tone, like exposed flesh.
Ikumi gulped, heat rising within her. It was her first time seeing something like this. She couldn't believe it. This wasn't just something small or ordinary—this wasn't a "third leg" at all. It was unmistakably a massive, thick penis.
"Sister, tell me… you have this too, right?" Harmonia asked, clearly confused as to why Hermay said Sister Ikumi didn't have something that made her daily life so complicated.
Ikumi heard her and swallowed the scream threatening to escape. With a trembling voice, she said,
"H-Hamy-chan… I—I don't have such a th-thing… o-only… m-men have those."
"What? Y-you really don't have this? Then why do I have one?" Harmonia asked, her tone filled with defeat. It seemed she had been experiencing something no one else did. "So even little Kaoru doesn't have this?"
Ikumi didn't understand why Harmonia lacked such basic knowledge. From her voice alone, she could tell she was genuinely bewildered.
Ikumi exhaled deeply, trying to steady herself, yet her eyes remained glued to the partially exposed shaft before her.
"Hamy-chan… you don't know it, do you? Of course, Kaoru-chan is a man, so he has it."
"Oh… really? Then how does little Kaoru control this thing? It keeps slapping my legs, and it really hurts a lot," Harmonia asked, seeking an answer—a solution to her problem.
That was when realization struck Ikumi. She had noticed that only a portion of it was visible— and the rest was missing. Her eyes widened as the thought hit her.
"H-Hamy-chan… w-where did you put the rest of that th-thing?" she asked, her voice shaking.
"Hmmm… well, I put it in the hole below it," Harmonia casually answered.
Ikumi couldn't understand what "hole" she meant. Trying to confirm it herself, she said,
"J-just stay still, Hamy-chan, okay? I-I'll l-look at it…"
"Okay, Sister," Harmonia replied, watching as Ikumi slowly knelt before her.
Ikumi's hands trembled as she lifted the rest of the skirt, fully exposing what Harmonia insisted on showing.
Sister Ikumi knelt on the kitchen floor, her eyes fixed on Harmonia's private area.
What she saw was another revelation that was hard to take in.
She saw that between her thick thighs was a curved, thick dick inserted into a woman's hole. There was a vagina below. She could not see the entire size and view, but judging by how the labia were being stretched so widely by the thick shaft, Ikumi deduced that it was truly a vagina—just like hers. A dick above and a vagina below… just what was this? Ikumi asked herself in bewilderment and awe at the discovery and the appearance of what lay before her. She swallowed at the thickness of the dick and the way the vagina was being stretched wide. Just by looking at how wide it was, she could tell how thick the penis was. It was like two of her legs put together, and yet the vagina was casually taking it in.
So that was why she had been acting strange, why she had been moaning, why her legs had been shaking—this was the reason. She had been putting this thick dick inside her pussy the whole time.
Harmonia then asked, "Sister, so how does little Kaoru deal with this?"
To Harmonia, who did not understand the difference between genders or human anatomy, she thought that if little Kaoru had one and Sister Ikumi knew about it, then perhaps she would know how to solve this problem.
"Hamy-chan… that would be impossible," she heard Sister Ikumi's voice say.
"So there's really no solution to this… but to just get used to it…" Harmonia's voice dropped low as she erased the possibility of finding an answer.
Sister Ikumi was still kneeling on the floor, her face turning red as heat rose within her. Her gaze remained fixed on the thick dick stretching that pussy, noticing how the vagina was extremely wet, producing soft slick sounds each time Harmonia took a breath.
"Hamy-chan… you don't really know the difference between a man's and a woman's private parts, do you?" Ikumi managed to say, her voice unsteady as her eyes stayed glued to Harmonia's dick and pussy.
"Difference?" Harmonia repeated. It was the first time she had heard about any distinction between the private parts of a man and a woman.
So she asked, "Hermay… what does Sister Ikumi mean?"
[Dear~ she is referring to the organs present at birth that are directly involved in reproduction.
A man, like little Kaoru, has external parts such as the penis and scrotum (which houses the testes), along with internal structures like the prostate and vas deferens—or, as you call it, that "third leg."
A woman, like Sister Ikumi, has internal organs such as the ovaries, uterus, fallopian tubes, and vagina, along with the external vulva—or the hole you have been using.]
"What… so a man and a woman each have only one of these? But why do I have two? Why do I have both?" Harmonia asked, still trying to process everything she had just heard. "And why did I forget to ask about this before?"
[Dear~ relax. Some people have it too, but it's a rare case, and it doesn't happen to everyone. You're simply one of those rare cases who has both. And don't blame yourself —you don't even know the difference between a man and a woman after all.]
Harmonia could only blame her own ignorance in this matter. She knew that Hermay only provided details and answers when she was asked; Hermay would only give information if prompted, so she could only blame herself for this.
She shook her head and said, "So it was like this… rare case? Like that dream?" That was one of the reasons she had assumed everyone was the same as her. In that dream, someone like her had the same condition, which led her to believe it was the same for others. But it turned out that wasn't the case at all. She didn't fully understand the context of what Hermay had said, but she was still able to grasp the meaning. That was why Sister Ikumi didn't have a third leg, and why it would be impossible for little Kaoru to offer a solution.
"I understand now," Harmonia muttered to herself. Her crimson eyes gleamed with clarity as she grasped her condition.
"Thank you, Hermay," Harmonia said.
[No need for that… Dear~] Hermay replied, though her tone carried something akin to a heavy regret, or something deeper.
"So only Sister Ikumi has the hole, and little Kaoru has the third leg—is that what you meant as well, Sister Ikumi?" Harmonia asked, addressing Ikumi, who was still kneeling on the floor.
"Y-yes, Hamy-chan… you finally understand it," Ikumi's voice replied.
Sister Ikumi was no longer simply kneeling; she had shifted into a low squat, her legs slightly spread as she steadied herself on the floor. Her right hand moved restlessly against the fabric of her black jeans, the subtle motion betraying her attempt to regain control of her own composure. Yet her gaze remained locked on Harmonia, drawn in by the overwhelming presence before her.
"Hmm~"
A soft, unintentional sound slipped from her lips as she struggled to steady her breathing. Her fingers continued their slow, repetitive motion as she fought to gather her thoughts, her cheeks still flushed with lingering heat. The atmosphere between them felt thick, charged with an unspoken tension as Ikumi tried to regain control of herself, even as her attention lingered on the pleasure that was building up.
However, her view was gradually obscured as a white shirt, followed by a long white dress slipping from Harmonia's grasp, fell back into place, fully covering her lower body.
The sight was covered, yet Sister Ikumi's face remained flushed a deep red, and her fingers were still moving over her lower body.
Harmonia looked down and saw Sister Ikumi with her legs spread wide, her eyes half-closed, and her face blushing.
"What's wrong, Sister Ikumi?" Harmonia asked.
Ikumi heard her, and somehow this brought her senses back. She stopped teasing her lower body, looked up, and met Harmonia's eyes.
"Hamy-chan! You're really full of surprises, and everything about you is big—so big," her voice was teasing and playful.
"Big?" Harmonia repeated, echoing Ikumi's words.
Ikumi slowly stood up from her squatting position and glanced at the hand she had been using to pleasure herself.
"Well, it's been a long time since I had anything like that, and it's my first time seeing something that thick," she said.
Her eyes then shifted back to the big girl. Harmonia's massive, thick member was tucked inside her own body.
Ikumi couldn't believe it. She was taking something that thick as if it was nothing. From the very start, ever since they met, she had already been doing this.
"Wasn't this basically like… fucking yourself?" she asked herself, struck by the realization.
"Hamy-chan… did you know you're a bad girl for doing that to yourself?" Ikumi said, her tone teasing.
Harmonia heard her but didn't understand what she meant. "Sister… what do you mean?" she asked.
Ikumi smiled at the girl's innocence. From Harmonia's eyes alone, she could tell she truly didn't understand what she was doing to her own body—completely ignorant of it all. A low chuckle escaped her lips.
"Fufufufu~"...
