Yoon Ji-ah: The First Treatment (1)
The moment I step out of the treatment room, the cool corridor air slaps against my sweat-soaked skin. The patient gown top clings stickily to my back, and the pattern engraved over my lower abdomen and testicles throbs in sync with my heartbeat. Hot one moment, cool the next—the uneven rhythm of my body temperature hasn't settled yet.
"How does it feel?"
Althea stands beside me, asking. Her purple eyes scan my face. The hand that had pinned my cock against my belly during the procedure now rests leisurely in her cardigan pocket.
"It's still... hot in there."
I answer honestly. More precisely, along with the heat, a pressure like the urge to ejaculate lingers inside my pelvis, but I can't bring myself to say it out loud.
"That's normal. It should stabilize by evening."
Althea nods and starts walking. We head down the corridor together toward my room. With every step, the pattern above my testicles pulses faintly, sending heat sinking down inside them only to rise again. That thing hangs half-swollen, draped outside the gown's opening.
At the door to my room, Althea opens it for me and says, "I'll come get you for lunch later. Until then, it's free time, so feel free to wander."
"How far can I go?"
"You can use the third-floor cultural facilities freely. Sodam Library, the screening room, the indoor plantarium. There's a ping-pong table and gym on the fifth floor too."
Althea counts them off on her fingers.
"The B1 cafeteria and pool are open for free use outside meal times. But you must wear a tip condom when leaving your room, and the orc guards at the first-floor lobby will check your ID."
"What about the fourth floor?"
"On the fourth floor, you can move freely between rooms and treatment rooms. The nurse station is fine to approach, and you can pass other patients' doors, but don't go inside."
I nod, and Althea brushes my hair back once before turning away.
"Rest up. I'll be back at noon."
The door closes, leaving me alone.
I head to the library on the third floor. True to its name, Sodam Library is a quiet, cozy space. Sunlight filters through the wooden bookshelves, and there's a single-seater sofa in the corner. No one's around as I browse. I grab a random book from the shelf and sink into the sofa. It's an essay collection, but the words don't register. The pattern above my testicles throbs as it's pressed against my thigh in this sitting position. Every faint vibration from the chair teases my dual prostate, sending weak jolts of pleasure from deep in my lower abdomen.
The sensation of Han Seo-yeon's brush gliding over my skin in the procedure room earlier, the weight of Althea's hot palm pressing down on my cock—they're still etched into my body. I flip through two pages and set the book aside. I pull out my phone, start an animal video, then turn it off and stare out the window. An hour and a half until lunch. Time feels frozen.
Lunch is in the same B1 cafeteria as yesterday. With the tip condom Althea fitted over me, we take the elevator down together, get trays from the serving line, and sit at the same window seat. Today's menu: barley rice, seaweed soup, grilled mackerel, seasoned soybean sprouts, and radish kimchi. The cafeteria is busier than yesterday. All six patients wear the same light sky-blue patient gowns, most with their cocks pulled out through the Y-slit, eating casually. One glances my way. A short-haired human woman. Our eyes meet, and we both look away at the same time. A strange solidarity with someone who shares my condition clashes with the instinct to avoid seeing each other.
Althea watches me occasionally from across the table as she eats her rice. She doesn't chat much like yesterday. Instead, after I finish my seaweed soup, she smiles and says, "You're eating well."
I return my tray and head back to the fourth floor. It's 12:40 by the clock.
"Ji-ah, rest in your room. We'll start your first treatment at 2."
"Treatment? Starting today?"
"Yes. Teacher Han said to begin this afternoon."
Althea speaks softly.
"The magic circle should be stabilized by now."
My heart races.
It's 2 o'clock. Knock, knock. I sit up in bed at the sound. The door opens, and Althea enters. Same uniform as always, but no cardigan today. With just the top on, the outline of her breasts stands out even more sharply than yesterday. Flesh peeks through the gaps between buttons, and pastel pink hair cascades over her shoulders. Althea closes the door and locks it. Click. She stands by the bed, looking down at me. Her purple eyes seem a shade deeper than usual.
"The first treatment is a back hug."
"A back hug?"
"Yes. I'll hug you from behind."
The explanation is simple. But imagining what that simple word implies makes the pattern on my lower abdomen pulse once, radiating heat. Her massive breasts pressing against my back.
"Please take off all your clothes."
"Everything?"
"Yes. Top and bottom."
Althea nods. Her voice is calm, like routine instructions.
"The more skin contact, the better the mana transfer efficiency. My body heat stimulates the magic circle to promote condensation. Fabric gets in the way and reduces the effect."
An expert explanation. But my brain processes it as Get naked and let this woman hold you. My trembling hands go to the buttons of my gown top, undoing the first one. As I unfasten the rest, the fabric parts, exposing my breasts. My pale pink nipples tighten in the cool air. I set the top on the bed. My upper body is bare.
"Bottom too."
I untie the waist string of the bottoms. As the fabric slides down, the purple pattern on my lower abdomen comes into view, and that thing, half-exposed through the Y-slit, is fully revealed as the pants drop. I kick them off my ankles and set them aside.

I'm naked. Standing before Althea without a stitch on. My abnormally large, engorged cock hangs half-erect between my thighs. The deep purple patterns are vividly etched on both testicles, their edges starting to glow faintly red.
Althea's gaze travels slowly from my breasts down to my cock and toes. Then back up to my face.
"You're beautiful."
My breath catches.
"Now, sit on the bed. I'll get behind you."
Althea reaches for the buttons on her uniform top. The first one pops open, and the taut fabric loosens, revealing a wide expanse of cleavage. Second button. Third. The top falls open, and what's inside spills out. A white bra cups her breasts, but flesh overflows the supports. Soft mounds bulge roundly above the edges, the deep, shadowed valley between them. Even with the bra, their weight sags them into heavy, rounded curves.
Althea drapes the uniform top over the chair back. Then she reaches behind, unhooks her bra. Snap. The freed breasts drop heavily with gravity, spreading slightly to either side over her ribs, swaying with their own weight.

Her nipples come into view. Thick areolas of deep pink spread wide, with fat nipples protruding boldly from their centers. I can't tear my eyes away. My gaze is nailed there, unmoving. Heat surges from my lower abdomen; the patterns above my testicles glow red, and that thing jerks upright from its half-flaccid state, thrusting toward my belly. A strand of Cowper's fluid dribbles from the tip, wetting my thigh.
Althea follows my gaze downward. The corner of her mouth curves softly.
"Quick reaction. That's a good sign."
With her upper body bare but skirt still on, Althea approaches the bed. I don't know when she slipped off her shoes, but she's barefoot.
"Sit in the middle of the bed. Legs straight out in front."
I obey, settling in the center with my legs extended. The mattress dips behind me as Althea's weight settles. I feel her kneel there. The air behind my back heats up suddenly, then a wave of scent hits me—lavender, warm milk, and succubus pheromones.
And then.
It touches. Something soft, hot, and heavy presses against my back. Althea's breasts envelop my entire back, soft flesh yielding between my shoulder blades, pressing in. Her body heat seeps through my skin like it's piercing straight into my muscles. I feel her nipples. Two firm points stab into the skin between my scapulae.
"Relax."
Althea's voice rumbles right behind my ear. Her warm breath grazes my earlobe, sending chills racing down my nape and spine. Her arms wrap around my waist, crossing over my belly. Broad, soft palms settle over the engraved pattern on my lower abdomen. The instant they do, it blazes red.
"Ngh…!"
The weight of her breasts against my back, the heat of her palms pressing my belly, her breath tickling behind my ear. Body heat floods me from three points at once, and the magic circle reacts, starting a heavy throbbing deep inside my testicles. I feel the mana moving. Something trapped inside them swirls, squeezed by the red glow of the magic circle.
"Nng… It's so hot…"
"The magic circle's reacting. That's good."
Althea's voice flows into my ear from behind. My earlobe trembles with every puff of her breath.
"Relax and lean back. I'll hold you."
I lean back, sinking deeper into her breasts. The soft flesh molds to the curve of my back, clinging tight. Her massive tits flow over my shoulders, sides, and waist, enveloping my entire back. It's hot. Not human hot. I'd known theoretically that succubi run warmer than humans, but feeling it skin-to-skin is different. The heat pierces my back skin, travels down my spine, and spreads to my pelvis.
Althea's chin rests on my shoulder. Pastel pink strands drape over my collarbone, lavender wafting from them.
"How's it feel?"
Althea whispers.
"H-Hot… and weird…"
"What's weird?"
"Inside my belly… something's moving. Around the magic circle…"
"That's the mana starting to condense."
Althea's palm traces slow circles over my lower abdomen. Each pass of her warm hand over the pattern makes the magic circle pulse and radiate heat, which sinks into my testicles and squeezes them. That thing throbs wildly against my belly. Cowper's fluid leaks endlessly, soaking around my navel, smearing sticky between her fingers.
"Excellent response, Ji-ah."
Althea's lips brush my earlobe. I can't tell if she's speaking or kissing. The soft flesh grazing my ear makes my whole body shudder. Her breasts heave against my back. Every deep breath she takes expands them, pressing harder, then they ease on the exhale. The rhythmic pressure and release kneads my entire back. The two hard nipples embedded in my skin scrape faintly up and down with each breath.
"Haa… ngh…"
I can't stop the sounds leaking from my mouth. Her body heat, pheromones, and the weight of her breasts are melting my brain's defenses. The patterns above my testicles glow a vivid red, pulsing faster. I feel the mana spinning and condensing inside them. Something is forming. Compressing into semen. The urge to ejaculate builds. Slowly but surely, pleasure swells like a tide from deep in my lower abdomen. That thing gives one big throb against my belly, my testicles contracting upward, tightening.
The magic circle reacts. The glowing red pattern shifts suddenly to purple, clamping down on my testicles. A physical force yanks them downward, the building urge slamming into a wall.
"Guh…!"
The blocked pleasure swirls lost inside my pelvis. On the verge of cumming but unable to—like in the procedure room earlier. But this time, with Althea's heat and breasts pressed to my back, the intensity is incomparable.
"Nng… H-Ha, Nurse Althea, it feels like… it's gonna come, but it won't…"
"Yeah, that's the magic circle."
Althea's voice flows sweetly into my ear from behind.
"You want to cum, right?"
No room for shame, I nod. My entire lower abdomen feels swollen with pressure, that thing gushing Cowper's fluid like mad.
"Good. That's the treatment, Ji-ah."
Her arms tighten around my waist, breasts pressing deeper into my back.
"Holding back the urge to cum. Maintaining this sensation. That's how we turn mana into semen."
Her palm circles over my belly again. Each loop makes the magic circle throb, squeezing my testicles, the sensation of mana droplets condensing into semen rising with it. I have to endure. In this pleasure, pressure, and heat—hold back without cumming. Althea's body heat is melting my back. Her breasts weigh on my shoulder blades. Lavender soaks my brain. Tears prick my eyes.
"You're doing great, Ji-ah."
A warm, leisurely, tender voice echoes behind my ear.
"Just a little longer."
