Second Treatment: Pinned Against the Wall
My eyes flutter open, and my body feels sticky. The patient uniform top clings to my skin, soaked with sweat, and there are dried streaks of Cowper's fluid blotched across my lower abdomen. The sheets are a mess too. I must have tossed and turned all night, because the blanket's half fallen to the floor, and the mattress is stamped with stains of sweat and pre-cum mixed together.
My cock stands rigid without fail. The magic circle on my balls pulses in time with my heartbeat, flickering from deep purple to red. My balls feel even heavier than yesterday. Probably because the mana is condensing inside them. As they rest on the mattress, they radiate a hot glow.
I glance at the clock—Althea will be here soon. I think about pulling the sheet over the stains, but it's pointless. She'd smell it anyway. I give up on picking the blanket off the floor and just sit there on the bed. Knock, knock. Right on time at 7:30. Morning sunlight pours in from the hallway, and there she stands in the glow—Althea, in the same uniform, same pastel pink braid. Her small horns gleam in the light over her cardigan-draped shoulders.
The lavender scent of Althea hits me, and my cock twitches hard, the magic circle on my balls flaring bright red. Her purple eyes sweep the room. No point hiding my erection—I'm just sitting there blankly on the bed with the blanket on the floor. She gets it immediately.
"Oh my."
Althea steps inside and closes the door. Her gaze flicks to the stains on the sheet, then up to my face. I didn't check the mirror, but I know my dark circles are worse than yesterday. She comes to the bedside, looking down at me with soft eyes.
"You endured all night, didn't you? The state of these sheets... it must have been tough."
Her warm hand rests on my head, gently sweeping back the tangled bangs from sleep. "You did so well holding out, Ji-ah. Really well." Her fingers trail behind my ear and down my nape in that familiar rhythm. It's just like how Mom used to comfort me when I cried about being sick.
"The first night after the magic circle is engraved is always the hardest. It starts condensing your mana, so your balls keep reacting. And right after the stimulation treatment too..." She knows all about how I writhed, soaked in Cowper's fluid all night.
"I'll change the sheets for you. It'll be like this every night, so don't worry."
This every single night.
"Um, Nurse Althea?"
"Yes?"
"What’s the morning treatment today?"
If the first one was the back hug, what's the second? No, I'm not looking forward to it or anything.
Althea smiles, her lips curving up as her droopy eyes soften even more. "It's a secret."
"A secret?"
"If I tell you ahead, you'll tense up. Tension lowers mana condensation efficiency."
Sounds like an excuse. A playful glint flickers in her purple eyes, then vanishes. "Go eat breakfast first. I'll be back at 10."
I head to the B1 Cafeteria for morning meal. I eat with the tip condom Althea put on me. There's a new patient I didn't see yesterday—an elf woman eating alone in the corner, head down. Her patient uniform looks brand new. Must have been admitted last night.
Back in my room, I fiddle with my phone. There's a message from Soo-bin.
I wonder what face the professor will make when I hand in a diagnosis saying Idiopathic Mana Mutation Syndrome. I sigh and flip the phone over. Ten minutes until morning treatment. My heart starts racing. Althea's secretive smile and the back hug replay in my head. What are we doing today? The magic circle on my balls starts glowing red. I hate how my body reacts to just thinking about it.
Right on time, Althea enters.

Today she's wearing just the uniform top, no cardigan. Cleavage peeks through, and her sleeves are rolled up to mid-forearm, revealing soft arms. She smiles down at me, her purple eyes a shade deeper than yesterday.
"Face the wall and stand straight?"
"The wall?"
"Yes. That one." She points to the blank wall painted white, nothing on it.
"And take off all your clothes."
Same orders as yesterday. Naked, I stand before the wall, staring straight ahead. My shadow flickers faintly on the white surface. The shadow of my cock rising above my belly is stark and clear.

Movement from behind. The rustle of her uniform coming off. Fabric settling on the chair. The click of her bra hook. The air behind me shifts. I feel the heat from Althea's bare skin before it even touches my back. Footsteps draw closer—soft bare soles on the floor. She stops right behind me, her breath grazing my nape.
"Don't move."
Her voice floats down from above. Because of our height difference, her breath warms my crown. Then her breasts make contact. Heavy, soft flesh blankets my entire back. I feel her firm nipples pressing in. Like yesterday, but different—her breasts settle onto my back from above, flowing downward with gravity. The massive mounds sag under their own weight, spreading along the curve of my back to either side. Flesh spills out beside my shoulders, brushing the sides of my arms.
"Ngh..."
A sound leaks out the instant her breasts touch. Althea's arms come around, wrapping my waist. Her hands rest on my lower abdomen. The magic circle reacts, blazing red. My cock stands fully toward the wall, the tip nearly brushing it. A strand of Cowper's fluid drips down and splatters above on the wall.
"Today we'll try even closer contact."
The whisper flows right by my earlobe. Warm breath seeps into my ear. Her lower abdomen presses against my ass. I feel fabric—must be her skirt still on—but her belly is bare skin. Her body envelops my entire backside from back to ass.
"Standing makes the mana circulation even better than yesterday."
Her explanation barely registers. The weight of her breasts and the hot press of her belly hit me all at once. Her palms start circling over my lower abdomen. Each warm stroke over the pattern squeezes my balls through the magic circle. I feel the mana spinning inside, compressing into semen. Is the density building as condensation progresses?
"Haa... ngh..."
My cock stands rigid toward the wall. Cowper's fluid flows nonstop, stretching like threads from the tip before plopping to the floor. Orgasm already builds. Just her body heat on my back and ass sends pleasure surging like a tide. The magic circle shifts to purple, pressing my balls to block release. The rebounding pleasure pools in my lower abdomen, swelling it.
"Nngh... Nurse... it's gonna come already, but it won't..."
"Yes, you're doing great. It's normal, so don't worry."
Her lips brush my earlobe as she whispers. Like this—facing the wall, embraced from behind—I have to endure with my cock hard and unable to cum.
"Ji-ah, you want to be discharged early, right?"
Her voice tickles from behind, warm breath dissipating along my nape. "You're a college student—must be busy."
Discharge. The word makes my head nod reflexively.
"O-of course... Group projects are piling up, and I missed Business Statistics attendance..."
Feels weird talking to a wall while naked, back pressed to a succubus's bare breasts. But I want to finish treatment fast and get back to normal life.
"Soo-bin said she'd cover the group project, but I still have parts to do myself... Gotta submit the diagnosis to the prof too—ngh!"
Sudden stimulation cuts me off. Althea's hands move. Her left hand rises from my lower abdomen, past my ribs to under my chest. My skin shivers. The broad, hot palm glides slowly along the outer curve of my left breast. It traces the contour: up the top curve, around the outside, sweeping the underside, veering inward just before the center—then turning back out. It circles the nipple without ever touching, teasing the edges.
"Ah, I was still talking—nngh..."
"Yes, keep going. About the group project."
Her voice is casual, like it's nothing. The gliding palm doesn't stop.
"S-so... the prof said if I submit the diagnosis, he'll count attendance..."
Althea's right hand circles over the magic circle on my lower abdomen, left hand strokes my breast. Both spots warming to her body heat—the circle squeezes my balls.
"Sounds good? No worries about school then."
Her left hand sweeps up from under my breast, grazing right beside the nipple. Her pinky brushes the areola's edge—so close.
"Nngh... there, it's gonna touch—"
It doesn't. The palm veers outward, circling back slowly. I'm going insane. My nipple hardens, protruding into the air. It shrinks and swells repeatedly, standing stiff. But Althea's hand keeps dodging it, teasing around.
"Nng... haa..."
Same on the right breast. It skirts the areola's border precariously, sweeping slowly from below upward. My body tenses every time it nears—then relaxes when it passes. The cycle drives me mad. Then her fingertip grazes the nipple. A split-second flick—her index finger brushes the stiff peak.
"Hiiik...!♡"
My back arches sharply. Electricity surges from my spine to my pelvis, striking the magic circle. It glows crimson, compressing my balls. My cock throbs wildly toward the wall. Cowper's fluid spurts in streams, splashing transparent lines on the white surface.
"Ohooh...♡ H-haa... nipples, touching the nipples... ngh...♡"
"Oh? So this is what gets you so sensitive?"
Her voice carries a warm smile. The palm resumes slow sweeps over my whole breast—avoiding the nipple—then tok. Her index finger flicks the left nipple lightly.
"Ohhooh...!!♡"
My waist buckles forward, pelvis thrusting toward the wall—my cock tip hits it. The contact shoves my ass back into Althea's lower abdomen. But it doesn't stop. My hips buck on their own. Rhythmically grinding my ass into her belly, then pulling away. My cock swings back and forth in the air, spraying pre-cum. Like a beast in heat. I know what it is in my head, but I can't stop. The magic circle blocks ejaculation, and the trapped pleasure screams at my body: Move! Rub! Do something!
"Nngh... haa... ohooh...♡ C-can't, can't stop—"
Althea's hands move. Her left from my breast grabs my hip. Broad, firm palm clamps over the bone; her right seizes the other side. Both hands lock my waist, pulling me tight. My ass presses flush to her lower abdomen. Her succubus-warm belly meshes perfectly with my curves. Her body swallows my back without gaps. The gentle but firm grip on my hips pins me—no movement possible. Sandwiched between wall and Althea, my waist frozen. My cock just stands toward the wall, twitching in the air.
"This treatment is passive."
Her voice falls from above. Her hands tighten on my hips, pressing down my twitching waist. "You moving on your own counts as active treatment—and that's risky for ejaculation."
If I thrust, I might break through the magic circle and cum. The thought terrifies me; I tense to stop my hips.
"Looks like we need a bit more time."
Her lips brush my earlobe. "So just stay still and take whatever I do."
Her hands stay locked on my hips. I'm fixed facing the wall. From my upright cock, Cowper's fluid streams down, drawing transparent lines on the white paint. The magic circle flickers crimson to purple. Instinct whispers to cum, but I can't move my hips. No, I have to get back to normal life.
"You're doing great."
Her warm, sweet voice flows from behind. "Just receive my treatment quietly."
Her right hand releases my hip—I sense it moving toward my chest. Please touch the nipple this time. I squeeze my eyes shut without thinking. Nothing but the wall in view, but I close them anyway.
