Gloryhole or Flesh Toilet — Same Difference
Female juices began spraying from Freyja as she hit her anal climax, jetting straight toward the hole where Senior Seo-rin waited.
She'd already been showing every sign of peaking, so the fact that she was going off and gushing something wasn't all that sudden — but the way she started hydro-pumping pussy juice? That was still enough to leave anyone stunned.
I was right in the middle of marveling at it when—
Psssshhhhh—♡
"Eek?! M-my eyeeeees?!"
"A-aah?! I'm so sorry♡ I'm so sorryyy♡"
Senior Seo-rin's scream came straight through from the other side of the hole. Faced with a sight neither of us could quite believe even looking at it, both I and the usually chatty Bok-soon were left speechless, blinking dumbly at each other.
"Good heavens. She's a first-class marksman, no less."
"Wait — that's what you're surprised about right now?!"
"Well, how could anyone not be surprised looking at that? She scored a first-shot bullseye without even zeroing in!"
"That… is true!"
"Y-you little bastaaards… not a single one of you is worried about meee♡"
At Senior Seo-rin's voice that followed — confirmation she was unharmed — Bok-soon and I snickered and leaned our faces toward the hole.
"You okay? Eyes not hurt?"
"Shall I offer chopsticks from this side? We can hardly go wasting Father's essence and Mother's blood, can we!"
"What is this, Xiahou Dun?"
"You shameless little brats — even now you're mocking me♡"
Her voice alone had been enough to guess, but sure enough — she was fine.
Kneading Bok-soon's breasts, I spoke again to Senior Seo-rin, who had returned to her post beyond the hole.
"So. Now you get it, right? Just how shameless we've been."
"Yes. I understand all too well. That far from being fully reformed, Master has only grown more wicked, more of a fiend. And that I must strive even harder — I felt that truth properly just now, through the holy water that struck me square in the eyeball."
"That so? Now that you know, what are you going to do about it?"
"Why, that is already decided! I shall remain ever closer at Master's side, training and supervising him, and with this filthy body and this pussy of justice, I shall perfectly reform Master's twisted sexual proclivities!"
"Doesn't sound like much has changed, though? Or has it? Now that you've become a hole I can use whenever I want… maybe not quite the same after all?"
Even while at home she was declaring she'd reform me — drilling a hole between our apartments and volunteering to become a gloryhole herself. There was no way things were the same as before.
"Hmph. How about it? Are your balls already trembling? Like Pavlov's dog, the moment I present my pussy you'll go spurt and creampie me — aren't you shaking with dread at that future♡"
"True enough. Twenty-four-hour close-contact drain-and-breed baby-making sex… yeah, that does make me a little tense."
"What a terrifying senior she is…!!"
"Hyaah…?!"
At Senior Seo-rin's declaration that she'd use her own body to milk me dry the moment my cock got hard — even if I was asleep — Bok-soon and Freyja started eyeing her again with the look reserved for fellow degenerates, licking their lips.
"Did you hear that just now? She said she'd do twenty-four-hour close-contact milking…?!"
"But clinging to Master and serving him is my duty…?!"
"…Come to think of it, you're an incredible pervert yourself."
Honestly, from where I'm standing, you're both about the same.
Same difference either way.
I clicked my tongue at the sight of these breeding sows — calling Senior Seo-rin a pervert while still sneaking glances at each other like they were the ones looking at a pervert — and turned to ask Senior Seo-rin, who was already murmuring "a-e-i-o-u" beyond the hole, limbering up her mouth.
"Why are you warming up your mouth-pussy, though? I'm planning to use the regular one."
"One never knows. Master might be using my pussy just fine and then suddenly decide, 'Ah, today I feel like finishing in the mouth-pussy,' and order me to present it."
"Thorough as hell. Alright then — consider it a test run. Put that mouth-pussy up against the hole."
"Mm. Leave it to me♡"
Faced with Senior Seo-rin's confident look, I gave each of the two still locked in their weird breeding-sow power struggle a cock-slap to the face and said,
"Keep that up and you're about to start grinding pussies together."
"Kyaah♡ Still not tired of these wicked deeds… What, you want us to get your cock hard for you, is that it?!"
"Using our mouth-pussies as cock-hardening tools… hyaah♡"
"These bitches won't even move unless you take the stick to them."
Chuuop—♡
Chuwap—♡
I'd hit the right cheek, so hitting the left one too only seemed fair. Only after I'd finally cock-slapped the left side as well did the breeding sows press their lips to my cock in perfect left-right harmony.
"Chuuooop♡ Chueup♡ After going at it like that all day long, look how healthy it still is♡ Chuuop♡ Truly, this is a cock that could sire eighty half-elf children on me and still have more to spare♡"
"Chuwap?! Th-then I'll bear a hundred! As a breeding sow myself, kyaah?!"
"Bok-soon wasn't issuing a challenge, so don't try to compete."
Left alone, one of them took the glans zone and the other the balls zone, dividing the territory nicely. I stroked both their heads while giving my cock a little warm-up time — and beyond the hole, Senior Seo-rin was already looking this way with a competitive glint, as if to say hurry up and come at me.
"Alright, time to get star— hey now, get off."
"C-can't we just taste it a little more?"
"Chueup-chueup—♡"
"Freyja is begging so earnestly, and it's just the taste of precum… aah♡"
"I said get the hell off!"
My cock was fully standing at attention by then. I slowly pushed it toward the hole visible beyond the wall—
"Chubooooop—♡"
—and on the other side of the gloryhole custom-fitted to my cock's size, the Female Knight's familiar mouth-pussy gently received the shaft that had come through.
"What, you're way more skilled than I expected? Don't tell me you practiced this too?"
"Chubooop♡ Not practice — call it training, undertaken to reform Master's twisted and misaligned sexual proclivities♡"
"A flesh toilet who still knows shame, huh?"
"Chubob♡"
Whatever her intentions, the truth was this: the same woman others knew as a gallant Female Knight had wanted cock so badly she'd drilled a hole between her apartment and her junior-slash-Master's place and volunteered as a gloryhole.
Of course she'd be embarrassed.
As if to prove it, the oral mucosa wrapping around me burned even hotter. My hips trembled as I started shifting my body this way and that, hunting for the optimal stance to use a gloryhole.
"Mmm… is this better? Or maybe like this?"
"Uuk♡ Uuup♡ Chuuuuup♡"
"Hold still. This is extremely important. Once I find a comfortable position for using this gloryhole, I'll be able to cum clean and hard — and that means I'll want to use my flesh toilet even more. If you don't want me drilling extra holes, stay put."
"…Are you actually understanding what he's saying right now?"
Bok-soon cut in, aghast, but I was too absorbed in adjusting the Female Knight gloryhole to even answer — twisting my body every which way, searching for the perfect posture to use this toilet-hole.
After maybe a dozen more trials and errors in that state—

Chubop—♡
"Ook♡"
"Oh?"
Like puzzle pieces locking into place — a sensation that was deeply satisfying and yet oddly unsettling — the cock that had been roaming Senior Seo-rin's mouth-pussy finally achieved perfect union with it.
It sank so completely into her throat that Senior Seo-rin and I both cried out This is it! at the same time.
"Doing a test run first was definitely the right call."
"Churp♡ Exactly so. Had I used the pussy straightaway, I might have spilled precious semen and urine♡"
"But we're not done yet. Just taking the cock well isn't enough for a passing grade on this hole — you know that, right?"
"Precisely. Only when Master can ejaculate at ease does it become a perfect toilet-hole. The arrogant notion of reforming Master with an incomplete hole never once entered my mind — so hurry, hurry, fill my mouth-pussy with thick, dense sperm♡ Chubop♡ Churrrrrp♡"
"Augh…"
Delivering a fine speech in that gallant voice and then suddenly chomping down on my cock was cheating.
I couldn't even see her face, and now she was sucking with such ferocious force it felt like I'd shoved my cock into a bottomless black hole.
"Chubobobobop♡ Chubooop♡ Chubooooop♡"
"Did you skip every meal today or what?! Why are you sucking like th—?!"
There was even something of being hunted about the sensation — and knowing that what waited on the other side was the masochistic Female Knight Senior Seo-rin only made it an irresistibly charming toilet-hole.
"But this is mouth-pussy only. How the regular pussy stacks up… maybe I'll think about that after I fire off one round."
"Uuup♡ Uup♡"
Senior Seo-rin's desperate fellatio was already bringing the semen up fast. I spoke to her as she thrust her snout through the wall like an octopus, vacuum-sucking my cock with enough force to punch through the plaster.
"Good. Swallow every drop…!!"
"Chuuoooop♡ Spray Master's baby batter all over my parched mouth-pussy♡"
Just as worked up as I was — a perverted Female Knight whose only thought was to drink down whatever I gave her, semen or piss.
Vrrrrrrrt—♡
"I'm cumming…!!"
"~~♡"

Deliberately ignoring the looks from the breeding sows on either side of me — staring as if I were the height of vulgarity — I unloaded my semen straight into the toilet-hole waiting beyond the toilet-hole.
