The fluorescent lights in Bay 02-02 never dimmed. The air smelled of disinfectant, warm latex, and the faint metallic tang of the restraint hardware. Tantou-kun—twenty-three, designated high-yield secondary donor under the national collection protocols—sat naked on the padded examination table, wrists and ankles already locked into the soft black cuffs. A thin collar with the bay number 020 rested against his throat. His cock, average length and still soft from the last forced orgasm twenty minutes earlier, lay against his thigh, glistening with residual lube and his own fluids.

The door slid open with a quiet hydraulic hiss.

Two women entered.

Kana-san was tall, broad-shouldered, brown hair twisted into a neat bun. Her white nurse’s uniform stretched tightly across a pair of heavy, soft breasts that moved with every step. A surgical mask covered the lower half of her face, but her eyes were warm and faintly amused. In one gloved hand she carried a pink cylindrical onahole still in its sterile packaging.

Ryo-chin followed, shorter, sharp pixie cut with a yellow streak, black face mask, and the same crisp white uniform that somehow looked more predatory on her. She carried a small tray of tools: prostate massager, two bottles of thick lube, a vibrating glans stimulator, and a collection dish already labeled with Tantou-kun’s ID.

“Both of them are so incredibly beautiful…” Tantou-kun thought, voice barely a whisper.

Kana’s eyes crinkled above the mask. “And I’m Kana, also in charge of you. Nice to meet you.”

Ryo-chin waved with cheerful energy. “Ah, sorry for the sudden introduction. I’m Ryo-chin, and I’ll be in charge of you. Just call out Ryo-chin if you need anything.”

They moved in perfect coordination.

Kana stepped to his left side and gently but firmly pushed his knees apart. Ryo-chin took the right. Four gloved hands settled on him at once—two on his inner thighs, one cupping his balls, one already wrapping around the base of his still-soft cock.

“First we check residual sensitivity,” Kana said, clinical tone softened by the smile in her voice. Her thumb rubbed slow circles under the head. “You came twice already this morning. The chart says your refractory period is short. Perfect for extended collection.”

Tantou-kun’s hips twitched. “Please… I just finished—”

“Shhh.” Ryo-chin leaned in, mask brushing his ear. “That’s the point of the treatment, Tantou-kun. We don’t stop when you finish. We stop when the dish is full and your preferences have been properly corrected.”

The pink onahole was unwrapped. Kana squeezed a thick ribbon of cooling lube into it, then slowly rolled the toy down over his half-hard cock. The internal texture was dense, ribbed, and deliberately tight around the glans. She began a steady, shallow pumping motion that never quite let the head escape the pressure.

At the same time Ryo-chin slicked two fingers and pressed them against his entrance. “Prostate first. Deep and slow. We want the prostatic fluid before the main load.”

The fingers sank in. Tantou-kun’s back arched against the restraints. A clear bead of fluid immediately welled at the tip inside the onahole.

Kana watched the droplet with professional interest. “Good reaction. Glans is already hypersensitive. We’ll keep the focus there.”

For the next twenty minutes the two women worked in seamless rhythm. Kana’s hand never left the onahole, twisting on every upstroke so the textured rings dragged relentlessly across the swollen head. Ryo-chin’s fingers curled against his prostate in matching tempo, occasionally adding a third finger when his breathing grew ragged. Whenever he approached the edge they both slowed to an almost cruel crawl, holding him there until the urge subsided, then started again.

“I can’t—please, it’s too much—”

“You can,” Kana answered mildly. “And you will. Multiple times.”

The first true orgasm of the session hit him like a seizure. His cock pulsed hard inside the onahole; thick ropes of semen flooded the toy and overflowed around the rim. Kana kept stroking through it, milking every spurt while Ryo-chin pressed firmly on the prostate, forcing additional clear fluid to mix with the load.

They did not remove the toy.

Instead Kana simply squeezed the base of the onahole so the collected semen stayed trapped against his glans, then resumed the slow pumping. The overstimulated head screamed with every pass of the textured walls. Tantou-kun’s thighs trembled violently in the cuffs. Tears gathered at the corners of his eyes.

“Post-orgasm sensitivity is excellent today,” Ryo-chin noted, almost cheerfully. She switched to the vibrating glans stimulator, pressing the broad flat head directly against the frenulum while Kana held the onahole halfway down the shaft. The dual sensation—tight silicone and focused vibration—ripped a broken sob from his throat.

They edged him for another twelve minutes before allowing the second orgasm. This one was thinner, almost watery, but the volume was still respectable. Kana carefully poured the contents of the onahole into the collection dish, then immediately reapplied fresh lube and rolled it back on.

“Third load should be mostly prostatic,” she said. “We’ll use the wand for that.”

The prostate massager replaced Ryo-chin’s fingers. It was curved, thick, and set to a low, relentless pulse. Combined with Kana’s continued glans-focused stroking, it produced a steady leak of clear fluid that never quite stopped. Tantou-kun’s cock stayed half-hard, twitching constantly, the head an angry flushed red.

They talked over him the entire time—soft, professional commentary mixed with gentle mockery.

“Look how much he’s leaking just from the head.”

“His balls are still full. We’ll get at least two more good ones.”

“He cries so prettily when we don’t stop.”

“Preference correction is proceeding nicely. He doesn’t even try to close his legs anymore.”

When the third orgasm finally arrived it was almost dry—short, sharp pulses of mostly clear fluid that made his entire body seize. Kana caught every drop. Ryo-chin kept the wand pressing against his prostate for a full minute afterward, drawing out the last involuntary spurts.

Only then did they pause.

Kana stripped the soiled gloves, snapped on a fresh pair, and wiped his cock clean with a warm cloth. Ryo-chin released the ankle cuffs just long enough to reposition his legs into a wider, more open stance, then locked them again. A new pair of soft thigh straps were added, forcing his knees higher.

“Phase two,” Kana announced. “Direct oral and manual glans work. No toy this time. We want pure head sensitivity.”

Ryo-chin lowered her mask just enough to speak clearly, then leaned down and took the entire head of his cock into her mouth. Her tongue worked in tight, focused circles under the ridge while Kana’s gloved fingers rolled his balls and occasionally brushed the shaft. The wet heat after the silicone was almost unbearable. Tantou-kun’s voice broke into wordless sounds.

They kept him there—Ryo-chin sucking only the head, never taking more than the first two inches—while Kana provided slow, teasing strokes to the rest of the shaft. Every time he neared climax they both stopped completely, waiting until the urgency faded, then started again.

By the time the fourth orgasm was allowed, Tantou-kun was crying openly, hips jerking uselessly against the restraints. The load was small but thick. Ryo-chin swallowed half, then let the rest drip into the dish Kana held ready.

They still weren’t finished.

A second onahole—this one narrower and more aggressively textured—was brought out. Kana applied it while Ryo-chin returned to the prostate wand. The combination of the tight new toy and the deep internal stimulation produced a continuous, low-level male squirting that filled the collection dish in thin, clear streams. Tantou-kun’s cock never fully softened; the constant dual assault kept him locked in a state of helpless, overstimulated arousal.

Kana’s voice remained calm and almost kind.

“You’re doing very well, Tantou-kun. Preference correction is nearly complete. One more full cycle and we’ll move you to recovery for six hours before the evening session.”

Ryo-chin’s eyes curved above her mask.

“Don’t worry. We’ll be gentle. Mostly.”

The fifth and final orgasm of the morning session was extracted with both women working the glans directly—Kana’s fingers and Ryo-chin’s mouth alternating in a relentless rhythm that left no part of the head untouched. When he finally came, the amount was small, but the intensity made his vision white out. They milked him through it until nothing remained but dry, painful twitches.

Only then did the toys and wand come off.

Kana cleaned him thoroughly, applied a soothing gel to the overworked glans, and noted the final volume on his chart. Ryo-chin unlocked the wrist cuffs but left the collar and ankle restraints in place.

“Rest for thirty minutes,” Kana said, already preparing the next set of tools on the side tray. “Then we begin the preference reinforcement phase. You’ll stay hard the entire time. That’s part of the correction.”

Tantou-kun lay trembling on the table, chest heaving, cock soft and shining under the fluorescent lights. The two onee-sans stood over him, still fully clothed, masks back in place, expressions calm and satisfied.

The collection dish on the counter held five distinct layers of fluid.

The treatment was only half over.

And the onee-sans in charge of squeezing had all afternoon left.
