Kim Haerin — Treatment (2)
The head of my cock parted her entrance and began to slide inside.
At first there was only the touch of slick flesh — the damp glide of gel mixed with her own juices, followed by that particular, yielding resistance unique to the inside of a pussy.
Nothing like an onahole. No matter how expensive the onahole, it was still just a thing you squeezed and pumped with your hand. Mora's pussy recognized my cock the instant it got close. The entrance gave a little pucker, caught the rim of my glans between its lips, and simply refused to let go. Quite the welcome.

I eased my hips forward, little by little. As the head sank deeper, a catching, dragging sensation rose from inside her.
"Hah…♡!"
A short sound shot out of my throat. What the hell is this?
There was a pattern in there. Soft flesh, but its surface narrowed and released in steady waves, raking the underside of my glans. Ring-shaped ridges, repeating in tight succession from the entrance all the way in — and every time the head climbed over another one—
Gnk— gnk—
—it snagged, and dragged, and let go. It felt alive, nothing like a lump of silicone. The walls dented to the exact shape of my cock, then snapped straight back and wrapped around it, each repeating fold seizing the head and hauling it toward the next ridge.
"N-Nngh…♡ w-wait…"
"Keep going in. You won't die from this much."
I honestly couldn't tell whether having a short cock was a blessing or a curse. The tiniest push of my hips drove the inner pattern right down onto my glans, and with a shaft this short, all that scraping stimulation concentrated on the head and the ridge beneath it.
Gnk— gnk—
That moment when the head caught on a ring, stalled for a beat, then slipped free — a stimulus that softly raked the edges of the glans. And on top of that, the rings were warm. They pulsed inside her, contracting in time with the throbbing of my cock.
"Hh, nngh…"
A thin moan slipped out and I clapped my mouth shut at once. This is getting dangerous. If just putting it in feels this good, how good would it be once I actually start moving? I'd assumed it would, at best, be a modest upgrade over an onahole.
Gripping Mora's legs in both hands, I pushed slowly forward. Maybe because of her slender build she was narrow inside — the entrance spread easily enough thanks to the gel, but past it everything was packed dense. The walls closed around my cock, tight from every direction. I'd assumed something my size would slip right in…
Stupid of me to think that, even for a second.
Tight. Genuinely, crushingly tight.
My glans climbed one more of those inner folds.
Gnk—
"Nnghh—♡!"
My spine locked rigid, toes curling against the sheet. Sparks shot from the root of my cock all the way up my spinal cord.
Only then did Mora lift her head a little. She studied my face through tired eyes, then glanced down to check.
"It's all in."
"Hah, haa… d-don't say it…"
Every bit of it was inside. The root of my cock pressed flush against Mora's soaked entrance, my balls hanging awkward against her flesh. Short as I was, burying it to the hilt hadn't taken long. But the moment it seated fully, her pussy wrapped around the whole length at once and squeezed. My short shaft was sealed inside her without a gap — glans pressed into the deepest point of the pattern, shaft wedged between the folds.
The urge to come hit me instantly.
"Ohh…♡"
Insane. Coming the second I get it in would be pathetic. I have to hold out. As long as I possibly can.
I held my breath and froze my hips. If I move, it's over. With the onahole too — when the urge spikes, you stop, and you can ride it out. Do the same here and it'll be fine.
Just think of her as a spoiled little mesugaki who does nothing but stare at her phone. I am absolutely not premature. Time to teach this insolent brat a lesson.
The pressure crept up my cock one more time. My balls drew up taut, and before I knew it, the hand clutching the sheet went white-knuckled.
Hold it! If I come the second I'm inside, she'll never let me hear the end of it.
I stole a glance at Mora. Our eyes met. She said nothing. Instead she picked up the phone she'd propped beside her, lit the screen, thumbed it unlocked, and checked something.
"Hey."
The words ground out between my teeth. "You're… checking your phone right now?"
"You were staying perfectly still."
"Do you have any idea what I'm doing right now?"
"Holding it in, obviously."
"You won't even help, and you're on your phone?!"
The instant I flared up, her walls gave a small squeeze. She's clenching on purpose every time I open my mouth. Either way, my glans pressed into the repeating pattern and got raked one more time.
"Nngh…♡!"
"Ooh, that was a close one just now, wasn't it?"
"No, it wasn't!"
"Sure."
That answer. That answer is infuriating. Whenever this nurse couldn't be bothered to argue, she just flattened everything with a single "sure."
I drew my hips slowly back. Even taking it out as carefully as I could, the inner pattern held my glans and wouldn't release it.
Gnk, gn-gnk—
Coming out was worse than going in — the folds caught in reverse and raked back along the ridge beneath the head. The tight walls stroked down my shaft, and a slick mix of gel and her juices followed me out, gliding from the entrance. Before long, my glans was back near the opening. I meant to catch my breath there before pushing in again; that seemed like the only way the urge would settle.
That was when Mora's legs moved.
Long, slender legs brushed up along my sides. The limbs that had been sprawled loosely across the bed swung around behind my back — and her ankles crossed.
"Huh?"
What is she doing? I lifted my head and stared at her. Smartphone in one hand, face utterly blank, she pressed her crossed ankles flat against my back.
The daisuki hold. I'd seen it a hundred times in doujinshi. I just never thought I'd be on the receiving end in real life — least of all from a dead-faced succubus like her.
"W-wait, what are you doing?"
"Securing you."
"Why?"
"Because if I go at the patient's pace, we'll be here until this evening."
Mora glanced at her screen, then looked back at me. "I promised not to call you premature, so don't hold back — come the moment you need to. Multiple orgasms make this go faster, you know."
I won't call you premature. Somehow that was worse than the insult itself.
"Who are you calling premature?!"
"I said I wouldn't call you that."
"Saying that IS calling me tha— ahk♡"
Strength flowed into Mora's legs. The ankles locked behind my waist yanked me hard into her, and I didn't stand a chance of bracing for it. My cock, nearly all the way out, plowed back through her entrance. My glans got swallowed into Mora's pussy, barreling over fold after fold all at once.
Schlrrrk—
"Hooooh…♡♡!!"
Sshluk.
It went all the way in. Driven by the force of Mora's legs, my small cock slammed home to her depths in a single stroke. The glans stopped dead in the middle of the deepest pattern, and the walls answered the impact by clamping down hard. My balls squeezed tight, the urge to come rocketed up — I could feel the semen already pooling inside my urethra.
"No, wai—"
Splurt—! Spluuurt—!
I came.
"Ohhooh…♡! Ohk—♡ ohh!"
Strange sounds were pouring out of my mouth. The load I'd been holding back for days gushed from the tip of my cock. Small balls meant there wasn't a huge volume, but three days of buildup had made it thick. The first rope pushed out in a heavy, sticky wave and clung to Mora's inner flesh.
Spurt—, splk—.
Short spurts followed one after another, my cock twitching over and over inside her. The semen didn't scatter thin — it clumped, thick and stringy, smearing across the walls and working its way into the folds of her pussy, sticking there. Unable to move my hips at all, held in place by her legs, I pumped my load into her exactly like that.
"Hah, haa… ffuck… seriously…!"
I hadn't even managed a single proper stroke, and I'd come anyway.
So fucking humiliating. No — wait. This happened because she yanked me in. Not my fault. I was obviously holding back. It was a daisuki hold, wasn't it? A position that makes you come no matter what. That makes it a medical accident. Right — the nurse's negligence. So this does not count as premature.
My cock shuddered one more time.
Spurt—
The last of it pressed into her insides and stuck there.
Mora's hand paused over her phone. Her face was as blank as ever, but her eyelids gave a small flutter.
"Ah."
A single short syllable. And then the inside of Mora's pussy twisted.
"Nnk…♡?"
I felt the change in full, through a cock still raw and hypersensitive right after coming. The walls didn't simply squeeze and release — they wrung inward, drawing my cum up and in. The sticky load I'd just fired seemed to melt and move between the layers of flesh, the inner tissue rippling along the path it had taken, even raking it out from between the folds and pulling it deeper.
"W-wait… what is th—♡"
"Absorption."
Mora said it flatly. The walls twisted deep once more, contracting as though winding themselves up around my cock. The sensation of my cum being pulled into her body was bizarre — less like being absorbed than like the walls themselves were eating it. Fold by fold they stroked over the sticky fluid and passed it down into some deep place inside her.
Mora's stomach gave a little jolt.
"Ohk♡"
A short moan. A light climax. But more vivid than any sound she'd made until now — nothing like the tired voice, the put-upon replies, the endless ranked-match whining. This was a suppressed moan ripped from somewhere deep in her throat.
Mora's thighs clamped down behind my back for one instant. The phone slipped from her fingers.
Plop.
It landed on her chest. Skinny as she was, there wasn't much there, but the phone still gave a small bounce on her uniformed torso. The screen was still lit.
Still panting in the aftermath, I looked at the screen floating in front of my face. A group messenger. Reading someone else's phone is obviously rude — but the display was pointed straight at me, and the text was crisp.
My breath stopped. Wait— what?
The messages above it scrolled into view.
My eyes snagged on that message and stayed there.
"……"
What kind of deranged succubus group chat is this?
And beneath that, Mora's reply.
And the last one was a sticker — a tiny succubus character mid-shriek, "NOOOO!" speech bubble and all.
My brain stalled out for a moment.
Real cock. Three days aged. Caked in dick cheese. Sent by that deadpan mobile-game nurse. About me. In a group chat?
"Hey."
My voice had gone low. Mora's eyes were still half-lidded, perhaps still riding the afterglow of her little climax, a faint flush warming her cheeks now that she'd finished absorbing. Only then did she look down at the phone lying on her chest — and register that its screen was facing me.
"Ah."
The sigh of the caught.
"You saw?"
"What do you think?"
"Then nothing to be done."
"'Nothing to be done'??"
My voice climbed higher and higher. Not that it mattered — my waist was still locked in her leg hold, and my cock was still inside her. Hardly a position of strength from which to file a grievance. Honestly, the fact that I was even trying to argue while looking like this was laughable in itself.
"'Real unwashed cock'?"
"I was instructed to avoid any direct reference to the patient in question."
"'Three days unwashed, caked in dick cheese'?"
"Status description."
"'Blowjob doable'?"
"Preference survey."
"'Cheese-like richness'?!"
"That one wasn't me."
"The problem is that you discussed it with your friends at all!"
My hand moved on pure reflex. Nearest target: Mora's thigh. I smacked it.
Slap!
The sound rang out sharp and clear through the treatment room. Mora's eyes widened a fraction. The flesh of her thigh shivered, a faint red bloom starting to rise where my palm had landed.
A beat of silence.
Mora picked up the phone and killed the screen. Then she looked at me. "Outpatient discharge guidelines: unauthorized violence is prohibited."
"That's not violence, that's a perfectly justified expression of anger?!"
"I can put it in your medical record. 'Patient struck nurse's thigh during treatment.'"
"Go ahead and write it! Because I'm filing a complaint that the nurse spread degrading gossip about a patient's genitals!"
Mora went quiet for a moment. Her eyes traveled down — from my face, to my hips, to the cock still sheathed inside her.
"Patient."
"What!"
"It's getting hard again inside me. Because you're angry."
"……"
It was true.
