Chapter 2** **Collection and Storage of Semen from Men with Excellent “Correction” Genes** **Extraction Bay 02-02 – National Medical Facility** **Adult Characters Only (18+)**

The thirty-minute rest period ended the moment the door hissed open again.

Tantou-kun still lay on the padded table, collar locked, ankles re-cuffed after the brief stretch. His cock—soft, slightly swollen, and visibly smaller than average—rested against his thigh, the head still flushed from the morning’s five extractions. A thin sheen of the soothing gel Kana had applied earlier caught the fluorescent light.

Kana-san and Ryo-chin entered without speaking at first. Both had changed into fresh gloves. Kana carried a narrow, transparent onahole designed specifically for focused glans work. Ryo-chin held a slim, curved prostate wand and a small bottle of warming lube that smelled faintly of mint.

“Preference reinforcement phase,” Kana announced, voice calm above her mask. “We keep the focus on the head. Your chart shows excellent volume for your size, but the sensitivity needs further conditioning.”

Ryo-chin stepped between his spread knees and gently lifted his soft cock with two fingers. “Still so cute when it’s like this. Small, but it tries so hard.” She gave the shaft a slow, almost affectionate stroke that made it twitch. “We’re going to make it try harder.”

They began without further warning.

Kana rolled the narrow onahole down until only the head remained trapped inside the tight, ribbed chamber. She started a short, rapid pumping motion that never allowed the glans to escape the texture. At the same time Ryo-chin slicked the wand and pressed it into him, seating it firmly against his prostate on the lowest continuous setting.

Tantou-kun’s hips jerked. A clear bead of fluid immediately appeared at the tip inside the toy.

“Good,” Kana murmured. “Prostatic response is still strong. We’ll keep him leaking while we work the head.”

The next forty minutes were dedicated almost exclusively to the glans.

Kana varied the pressure and speed of the onahole—sometimes slow and twisting, sometimes fast and shallow—always keeping the textured rings dragging across the most sensitive ridge and frenulum. Whenever his breathing grew ragged she slowed just enough to deny the peak, then resumed. Ryo-chin matched her rhythm with the wand, occasionally increasing the intensity for a few seconds to force another thin spurt of clear fluid into the toy.

Tantou-kun’s voice cracked repeatedly.

“Please—Kana-san—it’s too much on the tip—”

“That’s the point of correction,” she answered, never stopping the short strokes. “The head learns to give fluid even when the rest of you wants to stop.”

Ryo-chin leaned in, mask brushing his thigh. “Look how red it is already. And it’s still only half-hard. Small cocks are perfect for this kind of focused work. Everything stays concentrated right where we want it.”

They edged him through two dry peaks—sharp, almost painful contractions that produced only a few drops—before finally allowing a full orgasm. The load was modest but thick. Kana carefully emptied the onahole into the collection dish, wiped the head clean, and immediately reapplied the toy.

“Again,” she said simply.

The second cycle was slower and more deliberate. Kana used only her gloved fingertips for long stretches, rubbing tight circles under the ridge while Ryo-chin kept the wand pulsing deep inside him. The dual assault kept him in a constant state of leaking arousal. Tears gathered at the corners of his eyes; his small cock twitched helplessly inside the narrow silicone.

When the next orgasm was finally permitted it came in short, almost apologetic pulses. Kana milked every drop, then spent a full minute simply holding the overstimulated head between thumb and forefinger, rolling it gently while he whimpered.

“Preference correction requires repetition,” she explained, as if lecturing a student. “The more we overwork the glans, the more reliably it produces on command. Your size actually helps. Less surface area means we can be very precise.”

Ryo-chin replaced the onahole with her mouth for the next round—taking only the head, never more. Her tongue worked in slow, wet circles while Kana’s fingers stroked the short shaft and occasionally squeezed the base to keep him from softening completely. The wet heat after the silicone was almost worse. Tantou-kun’s thighs trembled in the cuffs; soft, broken sounds escaped him with every pass of her tongue.

They denied him three times in succession, stopping the moment his breathing hitched, waiting until the urgency faded, then starting again. By the time they allowed the climax, his cock was an angry red and so sensitive that even the air moving across it made him flinch. The resulting orgasm was small, almost dry, but the intensity left him shaking.

Kana recorded the volume, then looked down at him with calm satisfaction.

“One more cycle before we move to recovery positioning. This time we combine everything.”

The final round used the narrow onahole, the prostate wand on a higher setting, and Ryo-chin’s fingers alternating with Kana’s on the exposed base and balls. They kept the stimulation relentless and focused on the head, forcing him through one last, extended edge that lasted nearly ten minutes before they finally let him finish. The collection dish received only a few thick drops, but the chart note Kana wrote was positive:

Glans response: highly conditioned. Residual sensitivity excellent. Ready for extended evening session after recovery.

They cleaned him thoroughly, applied a fresh layer of cooling gel to the overworked head, and loosened the ankle cuffs just enough for circulation. The collar stayed locked.

Kana stripped her gloves and made a final note on the tablet.

“Rest for ninety minutes. Fluids and light monitoring only. Evening extraction will begin at 18:00. Preference reinforcement will continue.”

Ryo-chin gave his soft, glistening cock one last gentle pat.

“You did well, Tantou-kun. Small, but very cooperative. We’ll see how much more we can get out of that cute head later.”

The two onee-sans left the bay together, the door hissing shut behind them. Tantou-kun remained on the table, chest rising and falling, small cock twitching occasionally under the fluorescent lights, the collection dish on the counter holding every drop they had taken from him.

The correction treatment was far from over.
