Many of the university students had eagerly signed up for Professor T's class on ecology, and it wasn't hard to see why. The charismatic professor had an impressive physique. His broad shoulders and toned body were evident even under his crisp plaid shirt, and the ample bulge in his pants didn't go unnoticed by the female students - and the male ones, for that matter.
“As I was saying,” he continued, his smooth baritone commanding the attention of the room, “mutualism benefits both organisms in the symbiotic relationship. For example…” His words faltered briefly as he pressed a hand to his chest, an unfamiliar tightness building beneath his rib cage.
It wasn’t painful, exactly. More like something pressing outward, as though his body had decided to rearrange itself. He shifted, clearing his throat. "Excuse me. For example, the clown fish and sea anemone..."
As Professor T spoke, his shirt seemed to cling to him more snugly than it had that morning, especially across his chest. He adjusted his collar, his fingers brushing against the fabric, and winced as his sleeve strained over his bicep. The uncomfortable feeling refused to abate, and now there was an odd pressure in his arms and back, like his body was swelling—pushing against invisible constraints. The students didn’t seem to notice, but Alex, seated near the back, tilted his head in quiet concern.
The tension mounted with every passing second. His broadening shoulders tugged at the seams, and he felt his shirt tightening, pinching across his chest and back.
"Class," he said finally, his voice calmer than he felt, "I think we’ll pause here for today. Please finish reading Chapters 8 and 9 before next time."
Confused murmurs rose as the students exchanged glances, but they began to pack their bags and head for the doors. Professor T sat down at his desk, lowering himself slowly into the chair as he pressed his palms against the cool wood.
Alex stayed behind, lingering near the exit. He watched as the professor shifted uncomfortably, his jaw tight and his brow furrowed.
"Professor?" Alex called hesitantly, taking a step closer. "You, uh… sure you’re okay? You looked like you weren’t feeling well."
Professor T looked up sharply. He was about to wave Alex off when another ripple coursed through his chest and arms, making him inhale sharply. A soft but distinct creak came from his shirt.
"I… I’m not sure," the professor admitted. His words were slow, strained. His eyes dropped to his forearms, now noticeably thicker, the sleeves clinging tightly to his growing muscles.
Alex stepped closer, concern flashing across his face. "Professor, your—your shirt…"
Professor T glanced down and saw it too. His chest had pushed forward, broadening, straining the front of his dress shirt. The top button pulled taut, the fabric stretched to its limit. Slowly, and with an audible snap, the first button popped free, bouncing onto the desk.
"Oh no," he muttered under his breath, his breathing hitching. A second later, another button gave way, then another, each one releasing with a sharp ping that echoed in the room. The exposed skin beneath was broader and thicker, his chest taking on a powerful shape.
"Professor, you’re, uh…" Alex’s words faltered. His blush deepened as he stared, barely able to look away as the growth continued.
Professor T let out a low, strained groan, gripping the edge of the desk as his biceps swelled, straining his sleeves to near-tearing. His shoulders pressed outward, rounding and stretching the shirt taut across his upper back until a seam at the shoulder gave out with a quiet rip.
His face, usually so composed, looked torn between awe and bewilderment. "This… can’t be possible," he said, his voice deeper, rougher. His arms shifted against his sides, the fabric popping as his growing chest pushed them outward.
Another button flew off, revealing the full expanse of his now-powerful chest. Sweat beaded lightly on his forehead, and his slacks, too, began to look increasingly tight around his thickening legs.
Alex stepped even closer, his heart pounding wildly. "Professor… this is incredible," he said softly, his tone reverent. "You’re… huge."
Professor T looked up at him, his brow furrowed, but a flicker of wry humor danced in his dark eyes. "Glad you’re impressed," he said, his voice a rich, velvety rumble that sent a shiver down Alex’s spine. "Because I’m still trying to figure out what’s happening."
The professor’s chest heaved as he took a deep breath, splitting his shirt further. Shreds of fabric hung loosely off his frame, revealing defined muscle underneath.
Alex's eyes darted between the professor's face and his incredible physique. "Whatever’s happening… I mean, you’re not hurt, right?"
"No," Professor T said after a moment, relaxing his grip on the desk. "I feel… strong. Different." His lips curled into a faint, self-aware smile. "And very under dressed."
Alex blushed furiously, stammering, "I—I can help you! Find something, I mean, or… whatever you need."
The professor leaned back slightly, watching Alex’s flustered but sincere face. his massive chest heaving with each breath. Alex couldn't help but notice the strained fabric of his pants. The professor's thighs had grown significantly, and his slacks were now clinging to his legs like a second skin. But it was what was happening at the professor's crotch that really caught Alex's attention...
