What the Hell Is All This Nonsense
Squelch… thrust… squelch… thrust…♡
“Hah… haaah… huff…♡”
My hips rolled forward with a leisurely, almost agonizing slowness—so drawn-out it would have made any onlooker grind their teeth in frustration, like a single frame of slow-motion film stretched to the breaking point—until my pelvis pressed flush against Senior Seo-rin’s royal ass, which I held locked tight in both hands.
“Hnnngh♡ Hah♡ How does it feel… the taste of a Female Knight’s asshole sampled right here in the underground dungeon…♡”
“Mmm, that asshole’s clamping down nicely. Must be because of that ability of yours that lets you do a Female Knight’s work better than any Female Knight. After a full thirty minutes it’s squeezing so good I can barely tell it apart from a pussy—except for the womb, of course.”
Thirty minutes had already passed since I’d first buried my cock inside her. Wondering if her heart had shifted even a little in that time, I asked. But Senior Seo-rin seemed determined to prove that a mere half-hour could never break her. She deliberately clenched the asshole still wrapped around my shaft, twisted her hips, and answered with a smile.
“No need to pretend you’re so composed♡ You want to thrash those hips, don’t you? You’re thinking about pounding so hard the afterimages blur, turning the Female Knight right in front of you into nothing but a flesh toilet, aren’t you?”
“Is that so? I wonder.”
“Don’t play dumb—hah♡ It won’t do you any good…♡ Through this noble asshole of mine I already know exactly what Master and Cock-sama are thinking—oh, ooooh…♡”
Squelch… thrust…♡

And of course, when I pulled out I kept the same glacial pace, slowly dragging every ridge of my cock across the walls that clung to it one by one.
“You know everything I’m thinking? Then you already know I’m going to keep doing this for another thirty minutes, right?”
“Another thirty minutes here…?! Hnn… Even if you do, it’s useless. I already know that thanks to how tightly my asshole is gripping you, Master is desperate to spray white piss long before any yellow piss. No matter how calm you act, the moment you dump your semen inside me I’ll climax through my asshole right away—ah?!”
“You’ll cum just from feeling my semen? Only if I flood you the way I always do. What are you going to do if I dribble it out in little intermittent spurts instead?”
“S-semen… as slow as the cock itself…?!”
Drip… spurt…♡
Senior Seo-rin, who had been eagerly waiting for my load to spray into her guts like piss, whipped her head around in panic.
“Th-that’s impossible! Forcing back semen that’s already trying to come out—if you do that…?!”
“Of course it hurts the cock when I pull this shit. How could it not? But hey… if I think of it as proper manners training for a cheeky flesh-toilet bitch, a little pain is worth it.”
“You vicious… You’re really going to train me thoroughly until I submit, aren’t you♡ You’re going to put LESSON 4 into practice perfectly♡”
“That’s right. Okay, going back in. If you want that asshole properly wrecked… you know what to do, right?”
“Kh… Don’t make me say the same thing over and over♡ Mere sexual torture like this will never make me yield♡ On the contrary, I’ll use this righteous asshole of mine to reform Master’s shameless sexual walls♡”
“Mm, sure, sure.”
If she folded right away it wouldn’t be any fun for me either.
Squelch… thrust…♡
“Oh… hoooh…?!”
I pushed the cock whose glans had been hovering just outside her asshole back into Senior Seo-rin once more.
And so, thirty minutes later—
“Hoooh♡ O-ooh♡ Th-this much still can’t make me—hoooh♡ s-submit—”
“Huh?”
Beep-beep-beep—
The phone alarm I had set to ring at exactly thirty minutes went off. Senior Seo-rin, who had been hanging her head and trembling, suddenly snapped her face up and twisted her hips toward me.
“Haa♡ Haa♡ O-one hour… a whole hour has passed…! There! H-how about that? I endured every second of it♡ I’ve splendidly proven that Master’s sexual torture—this cock-teasing torment—can never break me♡”
“Oh, you actually held out?”
“Haa♡ More than that, Master truly is merciless… To keep that snail’s pace for a full hour while ravaging my asshole♡”
“Mmm, impressive, impressive. That’s my flesh-toilet knight for you.”
“Praise will get you nothing♡ More importantly, after spending an entire hour slowly fucking my asshole, now you should—”
“Mmm, now we go for the two-hour record!”
“W-what?!”
The thunderbolt that left my mouth after all my cheerful agreement froze Senior Seo-rin solid. In that opening I wreathed both hands in a suspicious green aura and immediately began caressing her smooth abs.
“If just now was Master’s spite—Phase One—then from here on it’s Phase Two. Slow fucking plus womb massage… Think you can still hold out through this?”
“S-stop that?! You’re going to continue the orgasm-denial torture and add that filthy massage from yesterday as well?!”
“Why not? You get stronger from it, don’t you? And if you take the womb massage long enough you might even get to cum the way you want. I don’t see the problem.”
“I want to cum on Master’s cock, damn it?! On Master’s magnificent cock, while receiving your piss—oooooh?!”
Hands filled with the lustful will of an orc that wanted nothing more than to break a Female Knight glided gently down her abs and flanks, then suddenly splayed like a tyrannosaurus’s claws and dug hard into Senior Seo-rin’s lower belly.
“Hoooooh…♡ A-again, pushing the cock into my asshole while the wooooomb…♡”
“Mmm, after hours of that vibrator warming it up, it’s nice and soft. Easy to grab.”
“Heh… heeeeek♡”
Squeeze—♡
I gradually closed the space between my fingers and seized the proud Female Knight’s womb—true to her nature, a womb that knew no retreat—in both hands.
Already heated to the limit, Senior Seo-rin arched her back, ready to climax from the intense stimulation flooding her womb—
“Ghooooooh?! I-I’m cumming… cum—?!”
“Heh heh heh, who said you could cum on your own?”
“Y-you bastard…?!”
The instant before she tipped over I released her womb and pulled back. Senior Seo-rin bit her lip hard and roared with a mixture of shock, rage, and raw arousal.
“A flesh-toilet bitch trying to cum without permission? Again.”
“Ghoooooh♡ T-the wooooomb♡ You can’t grab the womb that hard again, if you do I’ll—ah?”
“I told you to ask permission. I figured a thick-headed girl would need some repetition training, but I didn’t expect you to be so dense you’d forget the words that just left your mouth.”
“Kh… Master, you bas—taaaard…♡”
“Let’s see just how far you can go.”
Another hour crawled by.
“Master♡ C-Cock-sama, just a little faster, please thrust Cock-sama faster♡ If you won’t send me over with the womb then at least with the asshoooole♡”
“What, about to cum again?”
“Yeees♡ I-I think I’m going to cum♡ I think I’m going to cum from the womb♡ Please, please let me cum♡ Whether it’s the womb or the asshole, smash either one to pieces, just pleaseee…♡”
Compared to earlier she had grown far more obedient, her face now much closer to that of a thoroughly corrupted, lewd Female Knight. She swayed her obscene tits and ass and flattered me with everything she had. Still working the slow piston into her asshole while massaging her womb, I spoke with clear satisfaction.
“Mmm, see? Flesh toilets really do need training.”
“Haa♡ Haa♡ Th-then…♡”
I nodded in approval and gently stroked her womb. Senior Seo-rin smiled in delight and swallowed hard, clearly hoping the climax permission was finally coming—
“Still, since we’re already training, let’s do one more hour. This is actually getting fun.”
“Y-you fiendish bas—taaaard♡ Master is a fiend♡ Trash♡”
“Look at that, the real feelings come right out. Again.”
“Ughgaaaaah…♡”
And another hour after that—
“Heeek♡ I’m sorry♡ I’m sorry for being so arrogant♡ I’m sorry for cumming without Master’s permission♡ I’m sorry for a mere flesh toilet daring to splash toilet water all over Master’s feet on my own♡”
“Yeah? Are you really sorry? Look me in the eyes once… hey, why are you staring at the ceiling?”
“Because Master is a god, a god who lives in the heaveeens… so I’m looking at the sky, uhi♡ looking at the skyyy…♡”
“Even your tongue’s completely melted. Well… counting the time you were left alone, you’ve been under sexual torture for a full five hours without a single break. It’d be weirder if you were still coherent.”
For three solid hours she had endured ultra-slow piston fucking combined with womb massage, plus vibrators, rotors, and a clit clamp. Even if she had wanted to pass out from exhaustion, my Sex Healing skill kept restoring her stamina with my fluids, denying her even the mercy of unconsciousness.
I grabbed her chin and yanked her face toward me.
“Anyway, I’m impressed you held out this long. So, you’re not going to climb over me again, right?”
“Yesh♡ I will never climb over you again♡ I, Lee Seo-rin, am Goo Seung-yong Master’s flesh toilet♡ A flesh-toilet knight♡ A filthy flesh toilet that exists only to receive Master’s semen and piss♡”
“A whole five hours… really… such a long, long time.”
“Nnghhoooh?!”
Slap—♡
We still had an investigation to leave for today, so it was a relief I’d managed to finish a decent amount of training before it got any later.
Thinking that, I immediately began slamming my cock hard inside Senior Seo-rin while preparing to release the piss that had been nagging at me for a while now straight into her asshole.
“Honestly, what is all this. Huh? What the hell is all this nonsense.”
“I’m sorry♡ I’m sorry for being such a stupid flesh toilet…♡”
“Yeah, let’s do better from now on. Got it? If you got it, kiss me. I’ll let you cum.”
“Yes♡ Please use my pussy and asshole however is most convenient for you♡ Please use them however Master wishes to use them, mmph♡ use them, h-huuuuuh…♡”

Pssssssssssssss—♡
After a few more thrusts I began pissing hard into Senior Seo-rin’s asshole; she climaxed right along with me, spraying her own piss.
