Chapter 302 Interlude: The End of Mayuzumi Yoshino*
Edited by: Kanaa-senpai
How much time has passed since I was entombed in this stone chamber?
In my current state, I feel neither hunger nor exhaustion. I simply exist in a vacuum where the only thing that remains is the “Heat”¹—a primal, s*xual hunger that triggers the moment anyone enters this room. Yet, there hasn’t been a single sign of a soul.
Years? Decades? Has it perhaps been over a century?
The ceiling of the stone room eventually collapsed, allowing me to witness the cycle of day and night again. But after so many sunrises and sunsets, I honestly grew weary of counting and just… stopped. Truly, no one ever comes. Once, they sought me out so fervently, holding me time and time again, until I eventually birthed things that weren’t even human. Now? Not a single person. Though, I suppose I should be grateful; without anyone here, the Heat doesn’t consume me.
The curse that he placed upon me was one of immortality, the Heat, and a total schism between my flesh and my spirit. No matter what is done to me, I cannot descend into madness. No matter how much my body loses control, my mind remains chillingly calm. I am a spectator trapped inside my own skin, forced to watch the sight of my own depraved, frantic self. I watch myself beg pathetically, offering my body, moaning, and climaxing. I see it all, never breaking.
(It would have been so much easier if I had simply gone insane. But my heart and body are a grotesque mismatch. My flesh has been marinated in pleasure to the point where it feels “good” no matter what happens, yet in the deepest depths of my soul, I am nauseated beyond belief.)
Immortality, as it turns out, is a miserable thing. When the ceiling caved in, I genuinely thought I could finally die. But the moment I was crushed, “Regeneration”² kicked in. My skin remains flawless and supple, never aging—a cruel, beautiful irony.
Then, it happened. The rusted iron door opened with a heavy, grinding creak.
”Huh? Is someone there…?” the boy asked.
”You’re right. A woman… Hey! Don’t look, it’s bad!” the girl cried.
The ones who entered were a boy and a girl. But they weren’t human. The boy had canine ears and a bushy tail; the girl had feline ears and a long, slender tail.
Demi-beastkin.
They were likely the descendants of my own offspring. I have hazy memories of mating with dog-like and cat-like monsters and giving birth to their kin. But that wasn’t the problem.
My heart hammered against my ribs. My body flushed with sudden heat, and my core began to ache and throb. Then, words I never intended to speak spilled from my lips.
”Aha, well now, if it isn’t a pair of tiny little guests-ssu. Hey, wouldn’t you like to feel good with me-ssu? Don’t you want to shove those micro-dicks inside me-ssu?”
I exhaled a hot, ragged breath. I spread my legs wide, displaying my entrance. It was already gaping open, twitching in anticipation. My body was fully prepared. (My flesh had lost its sanity, but my mind remained perfectly lucid. God, I hate this.)
”Huh? Ah… eh?” Luca stammered.
”Wha—wait, what are you saying, lady?! This person is bad news… we have to run!” the girl shouted.
”Hehe, I won’t let you escape-ssu. Come on, let’s do something feel-good together-ssu,” Yoshino said.
I lunged and seized the hands of the two children trying to flee. While my heart screamed for them to run, my body was intent on predatory assault. In the most s*xual sense, of course. I used sorcery to slam the door shut. Though the ceiling was collapsed, it was still five meters high; without tools, they couldn’t possibly climb out.
(Why did the ceiling have to be so high? Not that I could leave this chamber myself anyway. But regardless…)
”Come on, let’s get those pants off-ssu. Or would you rather I strip them off for you-ssu?” Yoshino asked.
”Uwah, hey, stop it!” Luca yelled.
Ignoring the boy’s protests, I yanked down his shorts. It was tiny, like a little c**ktail sausage, still covered in its sheath. It was almost cute.
”Hehe, what a cute micro-d**k-ssu. I think I’ll have a taste-ssu. Slurp,” Yoshino said.
”Hyah! Hey, lady, that’s dirty! That’s where I pee!” Luca cried.
”Mm, slurp… that’s true-ssu. But it’s not just for that, you know-ssu. Lick, slurp, lick-lick,” Yoshino replied.
”Hyuu!?” Luca gasped.
I took his micro-d**k into my mouth, my tongue swirling around the shaft. Under the stimulation, it began to swell and stiffen. An upgrade from a c**ktail sausage to a frankfurter. It was decent-sized for a kid. He’d probably grow up to be a real lady-killer with that thing. I used my tongue to peel back the skin, exposing the head.
”Mm… hah… fufu, now it looks like a grown-up’s d**k-ssu. Let’s try that again… Aahm, lick, slurp, squelch, shp-shp-shluuuurp,” Yoshino said.
”Hyah!? No, stop it! Stop, stop!? Kyiii!?” Luca screamed.
I performed fellatio with wet, vulgar sounds. The boy began to moan in a high-pitched voice, sounding almost like a girl.
”Nfu-fufu, does it feel goo-ssu? Squelch, slurp, shp-shp-shp,” Yoshino said.
”Hyahhh!? You shouldn’t… this is wrong! No, stop, stop…” Luca begged.
”Stop it!” the girl shouted.
I was suddenly shoved back. It was the other child—the girl.
”What do you think you’re doing, you pervert! Don’t do that to him!” the girl yelled.
The girl stood protectively in front of the boy. She glared at me, hissing with ragged breath to intimidate me. Just like a cat. Well, she is a cat-beastkin. She has spirit.
”Hiss! Fshaaa! You pervert! I won’t let you do anything weird to him!” the girl hissed.
”Fufu, hehe. You… you’re in love with this boy, aren’t you-ssu?” Yoshino asked.
”Wha-!? Wh-wh-wh-what are you talking about?! Luca is like a little brother to me, so it’s not…” the girl stammered.
(She was completely flustered. I definitely hit a nerve. Meanwhile, the boy—Luca—had his ears drooping. I guess being called a “brother” was a shock to him. It seems the feeling is mutual between them. I’m actually jealous. I never had that. My life was just doing it with people I didn’t like, or with Kakei after he became a monster. I never truly loved anyone. Well, among men, at least. I did love Sensei. I wonder what happened to him. He’s surely long dead. But these kids… their first time should be with someone they actually like. It’s a good thing I stopped before we actually “did” it.)
”In that case-ssu, we’ll start with you-ssu,” Yoshino said.
I yanked the girl toward me and flipped up her skirt. Oh, she wasn’t wearing any panties.
”Kyaaaaa!? Hey, what are you doing!?” the girl cried.
”Sniff, sniff… Hmm, smells a bit like pee-ssu. Lick,” Yoshino said.
”Hyaan!” the girl moaned.
I buried my face under her skirt and traced her slit with my tongue.
”Lick, slurp, lick-lick, slurp… Hey, do you wash here properly-ssu? You’ll get a disease if you don’t stay clean-ssu. Lick-lick, slurp-slurp, munch,” Yoshino said.
”Hyaun! Mm. None of your… business! Hey, let go! Hyah! Hyafun!” the girl cried.
As I spread her folds, I found a build-up of smegma, which I proceeded to wipe away with my tongue. It was quite a bit, and the musky cheese smell was intense. I really worry about their hygiene. The girl tried to push me away, but our strength wasn’t even comparable. I was only caught off guard earlier; I wouldn’t let it happen again.
”Here, you lick her too-ssu,” Yoshino said.
”Eh!? But…” Luca stammered.
”It’s okay-ssu. Girls feel incredible when their pussies are licked-ssu,” Yoshino replied.
”Pu… p**sy?” Luca asked.
”Yeah, right here-ssu,” Yoshino said.
I held her skirt up. The slit was drenched in my saliva and shut tight, but it was beginning to get wet from her own fluids now.
”Come on, lick-ssu,” Yoshino urged.
”Is it… really okay…?” Luca asked.
”No! It’s definitely not—hyafun!” the girl cried.
Lick. As the boy licked the girl’s slit, her body convulsed, and she let out a sultry moan that sounded nothing like her usual self.
”See? It feels good-ssu. So let’s lick-lick together-ssu,” Yoshino said.
”Wait, hold on… no…” the girl moaned.
”……Lick,” Luca whispered.
”Hyanan!?” the girl cried.
Being licked by the boy she loved made her let out a cute, high moan. Lick, slurp, slurp-slurp, lick. Slurp, slurp-slurp, mwah, lick.
”Ah, nya, stop, hinyaan! I said no! That place is dir—hanyaaa!” the girl moaned.
The girl was now completely helpless. Attacked by both me and the boy she loved, her breath turned hot and shallow. Her knees were shaking so much she could barely stand. It must have felt overwhelming. It was her first time, after all.
”No, stop it…” the girl begged.
”You’re such a liar-ssu. You actually love it and want more, don’t you-ssu… munch,” Yoshino said.
”That’s not… true… nnyahaaaan!” the girl cried.
When I gave her sensitive, hooded clitoris a playful bite, she let out a piercing, lewd cry.
”Tell the truth-ssu. It feels good, doesn’t it-ssu? You want more, right-ssu?” Yoshino asked.
”Ah, mm, kuhi, nnya! I don’t know, I don’t know! My crotch is all squishy and throbbing, it’s scary…” the girl cried.
”That fear is just the pleasure-ssu. If you stop fighting it, you’ll feel even better-ssu. What’s it gonna be-ssu?” Yoshino asked.
”Nnh… mm, nyafu! An! …Do it. I want more!” the girl cried.
”Hmm, honesty is the best policy-ssu. Come on, let’s lick her p**sy together-ssu,” Yoshino said.
”Okay, I get it now, lady. Slurp, lick, slurp-slurp,” Luca said.
”Hanyaaa! The licking feels so good!” the girl cried.
Her previous resistance vanished as she moaned uncontrollably. Even if she was young, she was still a female. Just like my own cursed body.
”Ah, ah, ah, ahh, nyaha! It’s incredible, the licking, the licking down there feels so good!” the girl moaned.
”Hafu, that’s your p**sy-ssu. I told you that before-ssu,” Yoshino said.
”Mm… p**sy… p**sy! It feels good! Lick it more!” the girl moaned.
Lick-lick, slurp-slurp, squelch-squelch.
The two of us continued to lap at the girl’s p**sy, making wet, obscene sounds. I had already cleaned away the grime, so it was pristine now. If I hadn’t… the boy probably would have been repulsed. I had no hesitation; I’ve licked away the filth of countless men over the years, so this was nothing.
”Ah, ah, ah, something’s… something’s coming! What is it? I’m scared, it’s scary!” the girl screamed.
”Mm… you’re almost at the peak-ssu. It’s okay-ssu. Just let it happen and come-ssu. It’ll feel like heaven-ssu,” Yoshino said.
She was a total novice, so her fear was natural. But once she experiences this… she might never be the same.
”Come on, go for it! Come-ssu!” Yoshino urged.
”Ah! I’m scared, it’s scary! Ah, it’s coming, it’s coming! It’s here, it’s coming!” the girl screamed.
”Come-ssu! Lick-lick-lick-lick-lick…” Yoshino urged.
As a finishing blow, I forced my tongue inside her and raked it against her v**inal walls. And then—
”Hinyaaaaaaaaahhhhhhhhh!” the girl screamed.
Splurt! Splurrrrrrt!
Despite it being her very first climax, she squirted a massive fountain of fluid. Perhaps she was a natural-born pervert. The girl collapsed onto her backside, her strength gone.
”Hinya, hahi… funya… ugh, I wet myself… hic, sniff… I’m, I’m so sorry… sniff,” the girl sobbed.
”That wasn’t pee-ssu. You squirted-ssu. When the pleasure is too much to handle, it just happens-ssu. It’s totally different from peeing-ssu,” Yoshino said.
”It wasn’t… pee…?” the girl asked.
”Not even close-ssu,” Yoshino replied.
(Well, some girls do end up peeing, but I decided to keep that little detail to myself.)
”Now, since you’ve had your turn, the real show is just beginning-ssu. Let’s see… Luca-kun, is that micro-d**k still ready to go-ssu?” Yoshino asked.
”Nn… ah… licking your p**sy… it’s just making me more frustrated…”
He was still rock-hard. To be stopped right at the edge without being allowed to come – it had to be agonizing.
”Alright, I’ll show you how to fix that frustration-ssu. It’s easy… just take that little micro-d**k of yours and put it inside this girl… uh, what was it?”
”Lumi.”
”Right, Lumi. Put it in Lumi’s p**sy-ssu. That’ll set you straight. Honestly, I wouldn’t even mind if you used mine-ssu.”
Luca’s throat hitched as he swallowed hard. Even if he didn’t fully understand, his instincts were screaming at him.
”Uhm… Lumi-chan³. Is it… okay?”
”…………Yeah.”
Lumi gave a small, shaky nod. She clearly understood what was happening – her face was practically glowing crimson.
”H-here, Luca… it’s okay. You can put it in.”
”O-okay…”
Lumi lay back on the floor, hiked up her skirt, and spread her legs wide. She bared the very p**sy that the two of them had been tormenting just moments ago. She reached her hands up to invite him in; she was ready for this.
”I’m coming in…”
”Ngh… mm, ah…”
Luca lowered his weight onto Lumi’s hips and pushed inside.
”Ah, god… it’s so tight…”
”Ngh, ah… ha… mnh… it’s okay, go… deeper… go all the way… nhaa-ah!”
He buried himself to the hilt. A single trail of blood began to seep from Lumi’s p**sy. It made sense – if she hadn’t been a virgin, she’d be nothing but a little lolibitch.
”Aah, inside Lumi-chan! It’s so hot! She’s clamping down on me! Ah! Ngh!”
”Nnyah! Ah! Wait, it still hurts a little… ah! Nyahaaan!”
Despite her protests of pain, her voice was dripping with honeyed sweetness. Both Luca and Lumi were being swept away by the tide of pleasure.
”Ah! Ah! Lumi-chan! Lumi-chan! Mnh, squish.”
”Ah, Luca, Lucaaa! Annh, chu, mnh.”
The two of them collapsed into each other, exchanging messy kisses. I watched their first time with a satisfied smile, practically patting myself on the back for doing such a “good deed.”
* * *
I wonder how much time passed? It must have been at least an hour. They kept going until they’d completely exhausted themselves with their first taste of ecstasy. Even for kids, beastman stamina is something to be feared.
”How was it-ssu?”
”It felt… so good… I…” said Luca.
”Luca was a bit too wild… but I… well, it felt good for me too,” Lumi added. “We probably would have ended up doing it sooner or later anyway. It was just a matter of time.”
Lumi was definitely the more mature one. She clearly knew what the act meant and what it implied for their future.
As I watched them, I realized something strange – my “original” self had surfaced. Usually, my lewd persona is the one in control. Maybe it’s because my partners were just children?
”That’s great-ssu. But shouldn’t you two be heading home soon-ssu?”
”Eh? …Ah!”
They had been so lost in each other they hadn’t noticed the sun was almost gone. If they didn’t leave now, the forest would be pitch black and dangerous.
”You’re right, we have to go…”
They hurriedly straightened their clothes and then turned to look at me.
”What is it-ssu?”
”Hey… are you really going to stay here forever?”
”…I guess so-ssu. I’m stuck here; I can’t leave this place on my own. So don’t worry about me. We’ll see each other again whenever you come back.”
That was how it was designed. I was about to tell them to hurry home, but…
”Then we’ll get you out of here.”
”Yeah, come with us. If you’ve been here this whole time, you must have been all alone. That’s so lonely. So… please?”
They both reached out their hands to me. (I shouldn’t take them,) my heart whispered. But after being trapped in this stone chamber for so long… the loneliness was a physical weight. I hesitated for a moment, then finally reached out and took their hands.
”A-ahaha… it’s a ruin-ssu… I expected as much, but still…”
I stepped outside. Beyond the stone chamber, the city where I had been imprisoned – Foxia – was a skeletal wreck. Buildings were half-collapsed or completely leveled; some still held their shape, but there wasn’t a soul in sight. It was no wonder no humans ever came here. It had likely been a hundred years… maybe two or three hundred since I was first locked away. Everyone I knew was gone. Curiously, the tears never came.
”Um… Big Sister, your clothes…”
Oops. I’d been naked for so long I’d completely forgotten. I still had my clothes, though – the school uniform I was wearing when I first teleported here, kept safe in my Item Box. I pulled it out and slipped it on. I skipped the underwear since I was still wet down there. As for a bra… it didn’t really make a difference either way. Thinking about it just made me feel hollow.
”What weird clothes – “
”You think so-ssu? I guess they are.”
”But… they look good on you?”
Why did he sound so unsure?
Regardless, I let them lead me toward their village. On the way, we passed a massive, once-luxurious mansion. The gates were shattered, the grounds were swallowed by weeds, and ivy choked the walls. It was a waste; it looked like it could still be habitable with a bit of work.
After walking for two hours, a settlement appeared. This was their home.
”This is our village!” said Luca, pulling me toward the entrance –
Wait.
Something just… throbbed.
”Hey Luca, Lumi! Where have you two been… and who is this?” a villager asked.
”Ah-hah! There are so many of you-ssu! Hey, won’t you come play with me-ssu? You can use my p**sy, my ass, my mouth – whatever you want-ssu! Let’s just fuck! I’m just a lewd, perverted, masochistic pig – a meat toilet! Please, everyone, fill me with your c**m until I’m a sticky, muddy mess-ssu! Ah-hahahahaha!”
The lewd persona had clawed its way back to the surface. And just like that, the cycle would begin again. They would all come to take turns with me.
The Nightmare never ends.

Summary:
Mayuzumi Yoshino, cursed with immortality and insatiable libido, remains imprisoned in a stone chamber. Her isolation is broken by two young beastkin children, Luca and a cat-girl, who are her own descendants. Forced by her curse, Yoshino begins to s*xually assault and ‘educate’ the children.
Following a s*xual encounter between the beastman children Luca and Lumi, the narrator is released from their long-term imprisonment in a stone chamber. They discover that centuries have passed and their former home, Foxia, is in ruins. However, the moment they reach a new settlement, the narrator’s corrupted ‘lewd’ persona regains control, signaling a return to a cycle of abuse.
—
Trivia:
- The mention of ‘birthing things that weren’t even human’ highlights the extent of Yoshino’s previous torment.
- The five-meter ceiling height emphasizes her physical entrapment.
- The survival of beastkin descendants suggests a wider world populated by the results of her curse.
- The mention of the school uniform and ‘Item Box’ confirms the narrator is an isekai protagonist from Earth.
- The ruined mansion is explicitly identified in the notes as Natsumi’s former home, linking this to a previous timeline.
- The narrator’s ‘throb’ (ズクン) acts as a physical trigger for their personality shift, suggesting a magical or cursed condition
—
Character Insight:
Yoshino displays a total dissociation between her rational mind (which feels pity and self-loathing) and her cursed body (which acts as a s*xual predator). She moves from predator to a twisted ‘teacher’ figure for the children.
The narrator shows a brief moment of maternal care and human connection toward the children, but this is immediately subverted by their ‘lewd’ persona’s resurgence, illustrating a loss of agency.
—
Lore And Worldbuilding Context:
The ‘Heat’ curse is revealed to be a biological override. The existence of beastkin as descendants of human-monster crossbreeding provides a dark origin for these fantasy races in this setting.
The world has progressed roughly 400 years; Greedia has fallen, and beastmen have established their own settlements in the ruins of human civilization.
—
TL Notes:
The use of ‘-ssu’ is a key speech tic for Yoshino in this state, contrasting her predatory nature with a veneer of informal politeness.
The author notes that Mayuzumi is a ‘Nightmare’ character who is effectively a prisoner of her own lust-driven secondary personality.
