The ninety-minute recovery window was only half over when the door clicked open again.

Tantou-kun was still on the table, collar locked, ankles loosely cuffed, soft cock resting against his thigh under a thin sheet. The cooling gel had mostly dried, leaving the head faintly shiny and still oversensitive.

Ryo-chin stepped in first, mask in place, eyes curved with open amusement. Behind her came a third woman he had not met yet—taller than both of the others, black hair tied in a high ponytail, glasses perched on her nose, white coat open over the same tight nurse uniform. A small name tag read Sensei – Supervising Extractor.

Ryo-chin waved cheerfully.

“Sensei’s busy right now~ She’ll come later, so you can introduce yourself again then~♪”

The new woman—Sensei—only gave a short nod and moved straight to the side cabinet, selecting a different set of tools: a thicker, double-layered onahole, a longer prostate wand, and a pair of soft thigh straps.

Ryo-chin hopped onto the edge of the bed and patted the mattress.

“On the bed. Let’s start right away♪”

Tantou-kun barely had time to shift before Ryo-chin’s gloved hands were on his ankles, unlocking the cuffs just long enough to reposition him. She pushed his knees up and outward.

“Spread your legs.”

The new thigh straps clicked into place, holding him open. Kana entered a moment later carrying a fresh collection tray. She took one look at the arrangement and smiled above her mask.

“There’s actually one other nee-san~♪” Ryo-chin announced, gesturing toward Sensei. “But she’s observing for now. I’ll go here~♡”

Ryo-chin climbed onto the table between his legs, kneeling so her body blocked most of his view of the room. Kana moved to his left side. Sensei remained at the foot of the bed, arms folded, watching.

Ryo-chin’s gloved fingers wrapped around his soft cock and gave it a slow, assessing stroke.

“Still small and sensitive. Perfect.”

She leaned down and, without warning, took the entire head into her mouth. The wet heat after the earlier gel made Tantou-kun’s hips jerk against the straps. At the same moment Kana’s hand slid beneath him, two slick fingers pressing into his entrance and finding the prostate with practiced ease.

“TIGHT~” Ryo-chin murmured around the head, the word vibrating against the most sensitive skin. She pulled off just long enough to speak clearly. “Ryo-chin likes going behind~♪ But today I’ll stay right here on the head.”

She sealed her lips around the glans again and began a slow, focused suction while her tongue worked tight circles under the ridge. Kana matched the rhythm with firm pressure on the prostate, forcing a steady bead of clear fluid to leak directly onto Ryo-chin’s tongue.

Tantou-kun’s voice cracked.

“Ah!! Wait—both of you at once—”

Kana’s free hand settled on his lower stomach, holding him down.

“Correction continues. The more we overlap stimulation, the faster the preference settles.”

Ryo-chin pulled off again, a thin strand of saliva connecting her lips to the shiny head.

“TADA!” she said playfully, holding up the thicker onahole Sensei had selected. She rolled it down until only the head remained trapped in the densest section of the texture, then began short, rapid strokes that never let the glans rest.

Kana increased the pressure of her fingers. The dual assault—tight silicone grinding the head and constant prostate stimulation—ripped a broken sound from Tantou-kun’s throat. His small cock twitched hard inside the toy, already leaking.

Sensei finally spoke from the foot of the bed, voice low and clinical.

“Note the response time. Glans is conditioning faster than average for his size. Keep the focus there. Do not allow a full orgasm for at least fifteen minutes.”

Ryo-chin and Kana obeyed.

They edged him with ruthless precision. Every time his breathing hitched or his thighs began to tremble, Ryo-chin slowed the onahole to an almost complete stop while Kana reduced the prostate pressure to a light, teasing pulse. The moment the urgency faded they resumed full intensity. Clear fluid steadily filled the tip of the toy and overflowed in thin strands.

Tantou-kun’s protests grew softer and more incoherent. Tears gathered at the corners of his eyes. His small cock stayed half-hard, the head an angry red inside the transparent silicone.

After the full fifteen minutes Sensei gave a short nod.

“Now.”

Ryo-chin immediately increased the speed of the onahole while Kana pressed hard and steady on the prostate. The orgasm hit him in sharp, almost painful pulses. The volume was modest but the intensity left him shaking. Ryo-chin kept stroking through every spurt, milking the last drops into the toy before carefully emptying it into the collection dish.

She did not remove the toy.

Instead she simply squeezed the base so the residual fluid stayed trapped against the overstimulated head and resumed the short, grinding strokes.

“Again,” Kana said quietly.

Sensei made a note on her tablet.

“Excellent. Preference reinforcement is progressing. Continue until the next full load, then switch to direct oral for the final extraction of this phase.”

Ryo-chin’s eyes curved above her mask.

“Yes, Sensei~♪”

She settled back into rhythm, mouth and onahole alternating on the sensitive head while Kana’s fingers never left his prostate. Tantou-kun could only lie there, legs forced open, small cock trapped in relentless, focused torment, while the three onee-sans worked him with calm, professional enthusiasm.

The collection dish on the side tray was already beginning to fill again.

And the afternoon session had only just started.
