Chapter 66: The Biological Benchmark
The sterile white light of the medical suite felt blinding compared to the cluttered chaos of the office. As they stepped further into the room, the hum of advanced machinery filled the air—a low, rhythmic thrum that sounded like the heartbeat of the Academy itself.
Sora’s fingers were still lingering on the fabric of Jun’s white shirt, having just finished unbuttoning the last of the fasteners. With a tender, lingering touch, she slid the garment off his shoulders, letting it fall carelessly onto a nearby chair.
Jun didn’t hesitate further. He stepped out of his trousers, revealing himself in only his boxers. His lean, athletic physique was now on full display under the harsh, clinical lights. His abs were carved with a precision that spoke of a disciplined lifestyle, and his shoulders were broad, tapering down to a snatched waist.
Leni circled him, her goggles now resting on her forehead, her eyes scanning him with a mixture of professional curiosity and raw appreciation. “Hmph,” she hummed, a small, appreciative smile playing on her lips. “Well-trained. Exceptionally well-trained. Your muscle density is far superior to the average Prime. Most of the boys in your cohort have the physique of a pampered house cat, but you… you have the build of a predator.”
She stopped directly in front of him, her gaze dropping to the waistband of his boxers. “Now, don’t be shy. Take off the boxers. I can’t get a proper biometric read if there’s fabric in the way.”
Jun began to slide the fabric down, but Sora, ever the devoted partner, stepped in. She sank to her knees in front of him, her movements fluid and natural. Her slender fingers gripped the elastic waistband, slowly pulling the boxers down his thighs. As the fabric cleared his hips, his cock sprang free, fully erect and pulsing with a heavy, thick need.
Because Sora was kneeling, the member snapped forward, stopping mere inches from her face. She let out a soft, shaky breath, her eyes widening as she looked up at the sheer size of him. She didn’t pull away; instead, she leaned in, her warmth radiating against the sensitive head of his cock.
Behind her, the other girls stopped their own undressing. Hana, Akane, and Mei stood frozen, their eyes locked onto the sight of Jun’s member.
Hana’s face exploded in a vivid crimson. She had seen him before, but the raw, uninhibited sight of him standing proud in the clinical light was different. She felt a surge of jealousy flare in her chest—not at Jun, but at Sora. The way Sora was positioned, the way she was practically basking in the presence of his cock, made Hana want to push her aside and take her place.
Akane, usually the picture of stoicism, felt her breath hitch. She looked away for a split second, her cheeks dusting with a soft pink, before her curiosity won out. She stared, her gaze analytical yet filled with a hidden, burning desire.
Mei remained the most composed, but even she couldn’t hide the slight widening of her eyes. She stared at the thick, pulsing veins of his member, her mind instinctively recalling the scent of him, her body reacting with a sudden, sharp throb of arousal.
“Right! Enough staring,” Leni commanded, though she didn’t look away herself. “Jun, get on the platform. Let’s get your vitals recorded before you launder the whole room with your testosterone.”
Jun stepped onto the circular scanning platform. A shimmering blue light swept over his body, a holographic display appearing in the air beside him. Leni scrolled through the data, her eyes darting back and forth. “Heart rate stable. Hormone levels… god, they’re off the charts. No wonder the girls are smitten with you. You’re practically a walking pheromone bomb.”
Then, Leni did something that made the girls gasp. She stepped forward, her eyes locked onto Jun’s member with an intensity that was almost predatory. Without a word of warning, she reached out, her hand closing around the shaft of Jun’s cock.
She didn’t just touch him; she gripped him with a firm, expert hold, her palm molding to his girth. She squeezed, testing the firmness, her fingers tracing the heavy, pulsing veins that ran along the length. “Impressive,” she murmured, her voice devoid of shyness. “Above average. No, significantly above average. I’ve seen the files on the other Primes, and let me tell you, most of them are barely functional. No wonder Sora was completely wrecked during your first time; she probably felt like she was being split in half by a battering ram.”
But Leni wasn’t finished. With a shameless curiosity, she began to “inspect” him further. She let her free hand wander, her fingers grazing the hard ridges of his abs and sliding down to the dip of his hip. She leaned in close, her breath warm against his skin, as she traced the line of his V-taper.
“Look at this muscle tone,” she whispered, her voice dripping with a mixture of scientific awe and raw lust. “The pelvic floor is exceptionally tight. The sheer power concentrated in this frame… it’s a miracle he hasn’t broken a few women already.”
She shifted her grip, her fingers sliding down to cup his balls, lifting them slightly to assess their weight. “Heavy,” she noted, her eyes widening. “The volume is staggering. I can practically feel the pressure building. Most Primes have a ‘standard’ load, but Jun… you’re a goddamn firehose.”
She then leaned forward, her face inches from his cock, inhaling deeply. “And the scent… it’s potent. Pure, raw virility. It’s almost an aphrodisiac just being this close to it.”
She gave his shaft one final, firm squeeze—a la gesture of approval—before pulling back just enough to look him in the eye. “You’re not just a Prime, Jun. You’re a biological anomaly. A masterpiece of reproductive engineering.”
The girls watched in a mixture of shock and arousal. Seeing Leni—a woman of science—so openly adore Jun’s anatomy made the tension in the room reach a breaking point. Hana gripped her own dress, her face flushed, while Sora felt a surge of possessive pride, knowing that the “beast” Leni was describing belonged entirely to her.
Sora blushed furiously at the comment, but she didn’t look away. She watched Leni’s hand move, her own pussy pulsing in sympathy.
Leni reached for a sterile glass beaker on the nearby tray, holding it in her other hand. “Let’s see if the performance matches the architecture,” she whispered, her eyes glinting with a predatory curiosity.
With a sudden, expert movement, Leni began to give him a handjob. She didn’t just move her hand up and down; she used a complex, rotating, squeezing motion. Her palm pressed firmly against his base, while her fingers curled tightly around the shaft, twisting slightly as she slid upward. Her thumb worked in a rhythmic, tantalizing circle, grinding against the sensitive rim of his glans.
As she worked, Leni let out a low, appreciative hum. “My god,” she murmured, her voice a mixture of professional analysis and raw desire. “The firmness… it’s like gripping a steel rod. I’ve handled dozens of Primes over the years, and most of them soften the moment they get a little bit of stimulation. But you… you’re just getting harder.”
Jun let out a low, guttural groan, his hips instinctively bucking forward into her grip.
Leni didn’t stop; she accelerated, her hand becoming a blur of movement. She shifted her grip, her fingers dipping down to tease his balls with a light, rhythmic pressure. She looked up at him, a mischievous, teasing glint in her eyes. “Look at you,” she teased, her voice dripping with playfulness. “Trying so hard to hold it together. I can feel your prostate pulsing against my palm. Tell me, Jun… how much longer can you fight it? I’ve seen ‘marathon’ types fold in seconds once I hit the right spot.”
Jun’s breath became a series of jagged gasps. He gripped the edges of the scanning platform, his knuckles turning white. He let out a deep, strained grunt—a sound of pure, concentrated tension—as he felt the pressure building at the base of his spine. He was hovering on the precipice, his entire body vibrating with the effort of not exploding.
“Oh, you’re right there, aren’t you?” Leni whispered, her voice a seductive taunt. She intentionally slowed her pace for a split second, teasing him with the sudden lack of friction, before slamming her hand back up the shaft with a punishingly tight squeeze. “Don’t fight it, Jun. Just let it go.”
Then, Leni leaned in. In a move that was completely unexpected and utterly shameless, she gripped his cock with one hand and leaned forward, taking one of his nipples into her mouth. She sucked on it sharply, her tongue swirling around the sensitive peak in a sudden, electric jolt of stimulation.
The combination of the expert, high-speed handjob and the sudden oral stimulation was the breaking point. Jun’s breath hitched, his muscles locking in a sudden, violent spasm. He let out one last, loud, guttural cry—a sound of complete surrender—as his body finally gave in.
With a final, powerful surge, he erupted.
Leni shifted the beaker expertly, catching the thick, white torrent of his cum as it surged out of him. She watched with a clinical, yet satisfied expression as the beaker filled with the heavy, creamy fluid.
The girls, who had been watching in a state of rapt fascination, reacted with a collective, audible intake of breath.
Hana was practically vibrating. Her eyes were wide, her pupils dilated as she watched the thick, white seed erupt from Jun. She felt a surge of intense jealousy, not at Leni’s clinical approach, but at the sheer, raw power of the release. She gripped the fabric of her skirt tightly, her knuckles white, her own pussy throbbing with a sudden, sharp need. I want that, she thought, her heart hammering against her ribs. I want him to erupt like that inside me.
Akane stood frozen, her breath coming in shallow, jagged gasps. She had spent her life training herself to be an observer, a silent shadow, but this was a sight that shattered her discipline. She stared at the way Jun’s muscles had locked in a violent spasm, her face flushing a deep, vivid red. A small, involuntary moan escaped her lips—a sound of pure, unadulterated longing. She had never seen such a primal display of virility, and it left her feeling completely exposed.
Mei, usually the most stoic, was breathing heavily, her chest heaving. She didn’t look away for a second, her gaze locked onto the thick, creamy fluid filling the beaker. To her, it wasn’t just a sample; it was the essence of the man who had managed to crack her cold exterior. She felt a wave of heat wash over her, her legs feeling weak. The sight of Jun’s surrender, combined with the raw power of his ejaculation, made her want to throw herself at him and taste him right there on the sterile floor.
Leni pulled her hand away, looking at the remnants of his seed on her fingers. With a slow, deliberate motion, she brought her finger to her lips and licked it clean, her eyes locking with Jun’s. “High viscosity. High volume. Exceptional quality,” she noted, her voice sounding satisfied.
She turned to the girls, who were still staring in a mixture of awe and arousal, their faces flushed and their breathing heavy. “Alright, my turn to be the observer,” Leni announced, pouring the sample into a high-tech analysis machine. “I’ll check the rest of you now. Line up. Let’s see if your internal architecture is actually compatible with a beast like this.”
