Chapter 4: The New Contest
The fluorescent lights buzzed overhead, a sterile counterpoint to the wet, ragged sounds filling the lab. Daniel’s heart was still pounding from Chloe’s loss, the phantom feel of her firm, augmented curves imprinted on his skin. Chloe herself was slumped in a front-row seat, breathing heavily, a sheen of sweat on her chest as she idly thumbed one pale nipple. She pouted.
“So not fair. He’s too wound up from her,” she said, nodding toward Mira, who was calmly wiping Daniel’s spend from her cleavage with a lab wipe, a small, victorious smile on her lips.
Professor Marsh checked her clipboard. The sharp lines of her face were illuminated by the screen of her tablet. “Physiological baseline is elevated, yes. That’s part of the experimental variable. Isabella? You’re next.”
Isabella, the redhead with the wide-set, freckled breasts, jumped as if shocked. Her curly hair was a vibrant chaos around her shoulders. She’d been watching, one hand tucked between her own thighs, her breathing shallow. The moment her name was called, her already-prominent nipples tightened into long, flushed points.
“Right. Okay. Yeah.”
She moved from her seat with a clumsy grace, coming to stand before Daniel. The scent of her, nervous and sweet, cut through the humid air. She didn’t say a word, just locked her wide, green eyes with his. Her focus was absolute, shutting out the twenty other watching women. She pushed her chest forward, letting the full, natural weight of her 36DDs sway.
“You liked her tits,” Isabella stated, her voice low and raspy. It wasn’t a question. “All that softness. You wanna see what mine do?”
Her hands came up, cupping herself, thumbs brushing over those long, erect nipples. She sighed, the sound shuddering out of her. Then she leaned in, not to envelop him like Mira had, but to guide him between the valley of her breasts. They were warmer than he’d expected, the skin surprisingly smooth, the asymmetry creating a fascinating, real texture. She squeezed her arms together, creating a tight, hot channel.
“Just watch,” she whispered, her lips close to his ear.
She began to move, a slow, rocking motion of her upper body. The motion was different. Mira’s had been a rhythmic, milking pressure. Isabella’s was a sinuous roll, her nipples, impossibly long and stiff, dragging along the sides of his shaft with every pass. He could feel every bump of the gooseflesh that rose on her skin. Her breathing hitched, becoming a soft, constant pant.
“Fuck, that’s good,” she murmured, more to herself than to him. Her eyes were squeezed shut now, her forehead damp. The competitive goal seemed to fade for her, replaced by a deep, singular pursuit of sensation. She bit her lower lip, her hips making tiny, involuntary circles against empty air.
Daniel gasped. The visual was overwhelming. The freckles dusted across the tops of her breasts, the fiery hair, the intense concentration on her face as she lost herself in the feeling of him moving within her grasp. He felt the pressure building again, a treacherous coil tightening low in his gut. She was good. She was too focused, too in tune with her own rising pleasure.
“Izzy, you’re gonna lose,” Jasmine called out from the sideline, a laugh in her voice. “You’re getting there.”
Isabella’s eyes flew open, glaring past Daniel’s shoulder. “Shut up. I’m not.”
But the spell was broken. The clinical part of her brain, the part that wanted the credit, reasserted itself. Her rhythm became more deliberate, more strategic. She sped up, the slick, dragging friction becoming insistent. Her moans turned into sharp, choked gasps. He could see the flush spreading down her chest.
It was a race neither could slow down. Daniel, oversensitive from two prior rounds, felt the inevitable surge. At the same exact moment, Isabella’s body went rigid. A sharp cry tore from her throat, her breasts clamping around him as waves of her own orgasm rocked her. He spilled over her hands and against her sternum, the pulses syncing almost perfectly with the tremors in her thighs.
For a long moment, there was only the sound of their shared, ragged breathing.
Professor Marsh cleared her throat. “Simultaneous peak response. A statistical tie. No point awarded.”
Isabella staggered back, releasing him. She looked dazed, triumphant, and faintly annoyed. She glanced at the mess on her chest, then back at Daniel. A slow, tired smile spread across her face. “Guess we both won, then,” she said quietly, before grabbing a wipe and retreating to her seat.
“Jasmine,” the professor said, her voice carrying a new, subtle tension. “You’re up.”
Jasmine was already on her feet. She’d shed her top completely, her small, perfectly round augmented breasts defying gravity. The scar lines underneath were faint, silvery whispers. Confidence radiated from her. She sauntered over, her pixie cut sharp, her dark eyes gleaming.
“Okay, lab rat. They’ve been using the soft approach. Let’s try some structure.”
She didn’t wait for him to recover. Her hands were firm and businesslike. She used one hand to guide him, the other to press her breasts together. The feeling was distinctly different. Where Isabella’s were yielding and warm, Jasmine’s were resilient, a smooth, unyielding firmness underneath the soft skin. The contrast was shocking, intensely stimulating.
“You like that, huh?” she said, watching his face. She wasn’t whispering. Her voice was clear, almost conversational. “The fake ones know how to hold a shape. No spillage.”
She established a fast, efficient pace. It was ruthless. She used the perfect, round orbs like a tool, her eyes on his, a challenging smirk on her lips. She moaned, but it was performative, loud and open.
“Yeah, just like that! Come on, Daniel, don’t make me wait all day!”
Her bravado was a weapon. The noise, the direct eye contact, the unapologetic way she used her body—it was overwhelming his senses. He was crumbling under the sheer assault of it. He could feel his control slipping away in a dizzying rush.
“That’s it,” she coaxed, her smirk widening. “I’ve got you. Just let it—”
“Stop.”
The word was crisp, cold, and absolute. It sliced through Jasmine’s performance.
Professor Marsh had stepped down from the instructor’s platform. She stood a few feet away, her sharp green eyes missing nothing. The front of her thin silk blouse was taut, her own long, pink nipples visibly erect against the fabric.
Jasmine froze, the rhythm breaking. “Professor?”
“You’ve achieved sufficient vasocongestion for observation. The point is secondary. Disengage.”
The command was professional, but the professor’s gaze was fixed on Daniel, on the glistening evidence of his imminent release. A strange, silent communication passed through the humid air. Jasmine, confused but obedient, let go and stepped back with a shrug.
Professor Marsh moved forward. The class held its breath.
She didn’t touch him with her hands. Instead, she stood before him, and with a deliberate slowness, she unbuttoned the cuffs of her blouse, then the front. She let it fall open. Her breasts were modest, slender, as described in her file. But her nipples were arresting: long, pale pink, and in their fully aroused state, they looked almost severe.
“The final measurement requires a control,” she said, her voice husky but still clinging to academic pretense. “A subject without competitive investment. Purely observational.”
She leaned forward, placing her hands on the arms of his chair, caging him in. She brought her chest to his face. The scent of her was clean soap and faint, expensive perfume, utterly different from the students’ sweet arousal.
“Document the response,” she whispered, her breath hot against his temple.
Then she brushed one of those long, startling nipples directly across his lips.
It was an electric shock. A jolt that went straight to his core. The intimacy of it, the blatant authority, shattered the last of his resistance. He made a sound, a helpless, broken groan against her skin.
She did it again, a slow, deliberate drag. Then she shifted, offering the other. Her clinical observation was a façade; her breathing was shallow, quick. He could see the rapid flutter of her pulse in her throat.
It was too much. The week of tension, the hour of relentless stimulation, the shocking violation of this final, personal boundary. His body convulsed. Release ripped through him, untargeted, landing on the sterile floor and the leg of the chair.
A collective, soft gasp echoed in the tiered room.
Professor Marsh stayed there for a long second, her nipple just touching his slack mouth. She finally straightened, her blouse gaping open. She looked down at the result, then at her own physical response evident in the taut peaks of her breasts. She closed her eyes briefly, swallowing.
When she opened them, the professor was back. “Class dismissed. Journals on physiological variance are due Friday. Include… personal contextual notes.”
She turned, buttoning her blouse with slightly unsteady hands, and walked quickly to her office, shutting the door firmly behind her.
The lab was silent except for the hum of the lights. Daniel sat, spent and trembling, in a room of twenty women who were now slowly, quietly, gathering their things, none quite meeting each other’s eyes. The experiment was over. But the air still crackled with everything that had been left unsaid, and everything that had just, irrevocably, changed.
