Castor Tan pushed through the heavy lab doors, his basketball jersey clinging damply to his broad chest and the shorts riding low on his hips, the sharp tang of sweat and exertion cutting through the sterile scent of chemicals and polished steel. Prof. Li Chang looked up from his workbench, his precise movements halting as the athlete's presence filled the space, that raw, masculine odor stirring something unexpected beneath his calm exterior. "You're late," the professor said evenly, eyes narrowing at the careless sprawl of Castor's arrival. "And clearly not prepared for this role."

Castor flashed a quick, energetic grin, wiping a forearm across his brow as he extended a hand. "Castor Tan, the new lab assistant. Sorry about the state—practice ran long, and I rushed over." Tension crackled in the air during those first instructions on handling the delicate equipment, Chang's voice steady but his gaze lingering on the way Castor's muscles flexed under the soaked fabric. "Your carelessness shows in more than just timing," the professor noted, voice low. "That sweat and disarray won't do here." Castor shifted, the heat rising in his cheeks, before muttering about needing a shower in the attached facility, already peeling off his jersey to reveal the taut lines of his torso, then shoving down the shorts to stand in nothing but snug white briefs that hugged the outline of his cock and balls, the fabric slightly translucent from perspiration. Chang couldn't look away, his pulse quickening at the sight of that athletic body—lean, powerful thighs, the subtle bulge shifting as Castor bent to grab fresh clothes, every movement deliberate yet unselfconscious.

He swapped the white briefs for a pair of red ones, the vibrant color contrasting sharply against his skin as he adjusted himself, fingers brushing over the confined length before tugging on crisp lab slacks and a button-down shirt that still left the damp sheen on his neck exposed. The professor's eyes traced the process, noting the way the red fabric strained slightly, hinting at growing arousal amid the professional setting, a magnetic pull building between them even as Castor straightened, ready to focus under that watchful intensity.

They moved to the workbench together, Chang guiding Castor's hands through the precise calibration of the spectrometer, his voice low and measured as he explained the delicate alignment of lenses and samples. Yet the athlete's scent lingered thick in the air—musk from the game still clinging to his skin, warm and earthy beneath the fresh shirt—drawing Chang's attention back to the broad shoulders flexing under cotton, the powerful thighs braced against the lab stool. His own cock stirred in his tailored trousers, thickening with each inhale of that raw, masculine heat, the outline pressing insistently against the fabric as he leaned closer to correct Castor's grip on a vial.

Castor caught the shift in the professor's posture, his gaze dropping instinctively to the prominent bulge tenting Chang's slacks, and the sight sent a jolt straight to his own groin. Blood rushed downward, his cock swelling against the red briefs and straining the front of his lab slacks, the ache building with a mix of embarrassment and undeniable thrill. The air between them grew charged, heavy with unspoken tension, Chang's calm authority now laced with the flush creeping up his neck. "Your presence is... distracting," the professor admitted softly, his eyes locking on Castor's with a steady intensity that belied the hunger beneath. "I can't maintain this focus with you like this. Are you willing to wear a cock cage, Castor? It would help us both channel this energy into the work—secure, controlled, so nothing interferes with precision."

The suggestion hung there, bold and intimate, as Chang's hand brushed lightly over Castor's forearm, the touch electric. Castor's breath hitched, his arousal throbbing harder at the dominant offer, a submissive pulse of agreement stirring deep in his chest even as his body betrayed him with another twitch of his confined length. He nodded slowly, the word "yes" forming on his lips amid the hum of lab equipment and the shared heat of their bodies.
