A Perfectly Rational Judgment
Swwwk.
Seated on the bed behind me, Ji-yun slipped her hand slyly through the gap in my shirt, right at my chest.
"Now then, our dear customer... what about these nipples of yours? I wonder if you're sensitive? Or maybe... ahh, my, so you are sensitive."
At first, wanting to savor the moment, she avoided touching the nipple itself, tracing slow circles around it with her fingertip before gently, softly grazing the very top of it.
"Ah... nngh..."
The moment I reacted to a woman's touch for the very first time, Ji-yun pressed her chest firmly against the back of my head and breathed a whisper straight into my ear.
"Customer, your moans are adorable... so don't hold back — let them out as much as you like. Even if you make an utterly pathetic sound, I promise I will never laugh at you or judge you for it... so go on... okay?"
As her fingertips teased the tip of my nipple, ticklish and light, she affirmed every embarrassing thing that spilled out of me during the act.
"What would make our dear customer feel even better, I wonder... like this?"
"Ahhng..."
"Oh, you like that too, do you? Then how about this? You like this one as well... hehe, aren't you just precious. Your moans, the sounds of what you love, the sounds soaked in pleasure — let every last one of them out. Don't hold anything back."
As if searching for exactly which technique would draw out my pleasure best, Ji-yun tormented my nipples in a dozen different ways, and each time, just as she'd told me to, I let out shameless, ugly moans without restraint.
"Oppa, look down here."
Just as I was drowning in Ji-yun's teasing of my chest, I noticed Sung-ha — at some point she had stripped off my pants and underwear entirely, and was now gently caressing my erect cock.
Kneeling low before me as if in submission, she gazed up at me with a bewitching smile in her eyes.
Lick...
Her cat-like, mischievous tongue flicked out, deliberately lapping at my urethra where my piss would come from — then suddenly she stared hard at my cock and asked:
"Oppa... do you need to pee?"
"Uh... n-, yeah..."
I answered, a little embarrassed, at her blunt assessment of my condition.
It was rare enough to feel a bodily urge while erect, let alone in a state of sexual arousal.
But I'd needed to pee even before talking with the monster, and with all the time that had passed since, my bladder was so full that the urge to relieve myself had reached its absolute peak.
"Sorry to kill the mood, but the bathr—"
"Just let it out, oppa."
"...Huh? Where?"
"Right here."
At my question, Sung-ha opened her mouth so wide I could see all the way down her throat.
At first I didn't understand what the gesture meant and could only blink at her — but the moment comprehension arrived, I was horrified.
"No, no matter how you look at it, that's—"
"Why? I love your pee, oppa. Don't go to the bathroom — just use my mouth as your toilet."
I knew the monster loved everything that came out of my body, but pissing inside my girlfriend's mouth was still an awkward thing to accept.
"Customer, your girlfriend is asking so nicely — why not indulge her? A girlfriend who loves you enough to drink even your pee is a rare find, wouldn't you say?"
Pausing her play with my nipples, Ji-yun prodded at my hesitation, subtly pushing me along.
Truthfully, Ji-yun was a monster too, but speaking through someone else's borrowed body, she felt like a stranger — and a herd mentality was quietly taking hold of me.
In the past, that psychology would have swept me up completely, but now that I'd adapted somewhat to the monsters, I could still judge things with a shred of composure.
"Well, that's one way to put it. But really, you just want to drink it yourself, don't you?"
I said it, recalling the wistful look on the monster's face every single time I went to the bathroom to take care of my bodily needs.
"You're right. I've been thinking every day — stop wasting everything your body produces into a toilet bowl, and just give it all to me, straight into my mouth. I'll always be by your side, so even when we go out, you can use me like a portable toilet anytime, anywhere, no matter the place. Isn't that convenient? My mouth can match the optimal temperature and pressure for you to urinate into. It's good for me, and good for you too — a perfectly rational and efficient arrangement, wouldn't you agree?"
Watching Sung-ha wipe her expression clean and launch into a lecture in the monster's tone of voice, I flinched back slightly.
...Urine was one thing, but no matter how I thought about it, that other thing was out of the question.
"Ahem. Then... e-, excuse me..."
I'd only hedged with the polite phrasing — this was, in truth, exactly what the monster wanted — so I had no choice but to try pissing into the monster's mouth.
Relieving myself into a woman's mouth — my girlfriend's mouth, no less — and having her swallow it filled me with a strange, transgressive thrill that made my skin prickle.
But reality didn't flow as smoothly as it does in a fetish video.
...Nnnh...
The moment I tried to pee while two beautiful women stared intently at my cock, the urine that had been ready to flow retreated right back inside.
Neither of them blamed me, got bored, or showed the least irritation — they seemed prepared to wait hours if need be. But regardless of their patience, no yellow liquid showed the slightest sign of emerging from down there.
Yeah, this really is hard to pull off in practice...
"Now then, customer. Let's relax a little, shall we?"
As if reading my psyche in real time, Ji-yun suddenly covered both my eyes from behind with her palms and spoke in the gentlest voice.
Churp.
At the same moment, someone wrapped their warm lips around the head of my glans, and I didn't need to look to know who it was.
"Slowly now... let the erection go... that's it... good... very good, customer."
Like a nurse soothing a patient before surgery, Ji-yun calmed my nerves with her soft, level tone.
And just as she intended, my erection subsided naturally — and in its place, the urge I'd been holding back came surging up.
Trickle...
Gulp... gulp...
"Hahh..."
As a shiver of relief ran through my body at finally releasing what I'd held in so long, the sound of a throat bobbing in urgent swallows echoed through the room, several times over.
Sluurp, smack...
Refusing to miss even a single drop of what remained at the tip of my urethra, she pursed her lips into a tight point and sucked insistently around my glans.
"Kuhu... delicious."
When the palm covering my eyes fell away, I saw Sung-ha wearing a slack, goofy grin — uncharacteristic of her, like when she'd sniffed at my armpit — utterly satisfied.
The one mercy was that, unlike that time, her eyes hadn't rolled back into madness.
"Now that you've relieved yourself so nicely... shall we get you hard again, with plenty of energy this time?"
Ji-yun resumed her abandoned work on my nipples and began coaxing my cock back to attention exactly as she pleased.
Sung-ha, for her part, swiftly swallowed me down again and gave me a blowjob tuned precisely to my preferences — the pressure, the temperature, the perfect pace, all of it fitted to me alone.
A threesome with beautiful women was every man's dream, and I, tasting that dream made flesh, could do nothing but savor the sweetness of the pleasure flooding every corner of my body.
"You know, given the structure of the human body, a person giving a blowjob can't really talk, can they? But with two of us, at least one of us is free to chat."
Ji-yun took my chin in her hand and tilted my head back, half-forcing me to look up at her face-on.
Holding my gaze dead straight for a moment, she then began to smile — a sadistic smile, like someone else entirely had taken her place.
"Feels good, doesn't it, you filthy pervert? Getting fondled by two women at once feels good, doesn't it? Well, of course it does. Two gorgeous women worshipping your body like this — what man on earth wouldn't love it?"
There was no way a monster so attuned to me could have missed what the little roleplay a few days ago had revealed — that I had a taste for masochism.
Naturally, the monster hadn't let that detail slip by, and the effect was devastating: my cock went rigid in a single beat.
"Our dirty little pervert... shall you have a go at noona's titties?"
Pop.
As Ji-yun undid the buttons of her white blouse, a plentiful pair of C-cup breasts spilled free of her bra with a soft sway.
Perhaps because of their fullness, they weren't the kind that defied gravity and surged upward like Sung-ha's, but hung with a slight, natural weight.
And unlike Sung-ha's pink-hued areolae and nipples, hers were a subdued, earthy brown.
With hesitant fingers I cupped the two mounds, and a sensation utterly unlike Sung-ha's — a plump, yielding softness too generous for one hand to contain — spread across my entire palm.
"Now, professionally speaking, I do address you as 'customer' with all due respect, but I'm very much your senior in age, you know. So with that in mind — come now, repeat after me. May I please suck noona's titties?"
"Haaah, nnh!... M-, may I please suck noona's titties."
With the pressure of her mouth working me from below and my brain's filters dissolved in pleasure, words I would have died of embarrassment saying on any ordinary day tumbled out without a second thought.
"There we go~ such a good boy, our Hyun-ok... Come on, Hyun-ok. Noona's giving you her milk-pouch. Drink up, little one."
Ji-yun stroked my cheek softly, then cradled one breast in her other hand from below and offered it to me like a mother feeding her baby.
Haap, chub, chwop...
I opened my mouth as wide as it would go and started sucking greedily, as if devouring some luscious, ripe fruit.
"That's it, my Hyun-ok. You love noona's breasts, don't you? Mmm~ yes... I love it too, having you nurse at my chest... Drink all you want. Drink until you've had your fill. For hours. For days on end. And once you're thoroughly sated, we'll squeeze out a nice thick load together, hm? At the very best moment, when you feel the very best you've ever felt, you'll let out the most delicious — ah, your semen, I mean. Noona is always on your side, you know... forever, and ever, for your whole life. Right up to the very moment you die."
Swwwk.
Ji-yun's eyes were turning a deep, monster-like crimson — but I was too busy feverishly worshipping her body to spare a single thought for it.
