Mr Blake crushed his glasses with his massive feet as he charged towards the students. He swung his arms manically, hoping to grab one of the boys who were desperately trying to get away. His monstercock left a trail of precum behind him as it bounced, slapping his abs and pecs. The silence of the room has been usurped with a cacophony of shrieks and deep, low grunts. Chris, Zach, Danny, and a few others sprinted back to the closed door, and began pushing it with all of their might. Zach grew red in the face, putting all of his weight into it. His arms tensed, giving Danny a good view of the boy’s impressive biceps. But it was no use; the door remained shut. Danny felt his heart drop with hopelessness.
“Don’t give up now!” Chris yelled over the noise, “I think I can feel it opening—“
“Sir! I’m here! Over here!”
They turned to see one of the Computing students stand boldly in the centre of the room, waving down Mr Blake. He was rubbing his hardon through his jumpsuit. The hulking teacher stopped dead in his tracks when he spotted the boy, and the two exchanged a deep stare, and the room was met with silence again. An intense silence, with Mr Blake occasionally grunting as his member throbbed with anticipation. The student inched slowly towards him, and the voice from the speaker returned.
“The power, the strength, the body. It’s something you crave, isn’t it Damien?” the voice whispered.
The Student nodded, his eyes fixed on Mr Blake.
“How do you know my—“
“Go to him. Bathe in his energy.”
Damien didn’t need to be told twice. He rushed to the teacher with open arms, and Mr Blake picked him up with ease, licking his lips as if a beast had found it’s meal. Damien rubbed his hands down the man’s chest, gripping onto the base of his cock with a smile. Mr Blake grumbled with his baritone and grunt-like voice.
“NICE…WET…MOUTH!”
And before Damien could react he felt his teacher’s rock hard member smother him. Mr Blake thrusted his cock into the student’s face, who had his mouth wide open to take in as much as he could. The teacher roared so loudly with pleasure the walls around them shook. Almost immediately he came, with spurt after spurt of cum launching straight into Damien’s mouth. Everyone watched in shock as his grip on the student’s head grew tighter, and they could hear Damien begin to gag and splutter at the sheer volume of the man’s seed that was pouring down his throat. The boy’s hands were pressed firmly on Mr Blake’s chest, trying to push away, but to no avail. He swallowed and swallowed and swallowed. Just before he ran out of air, Mr Blake let him go, and he stumbled to the floor, coughing violently and gasping for breath. His jumpsuit was completely drenched, and his hair was stuck to his scalp. Mr Blake stood over him, the last remaining loads slowly cascading down onto the boy like a waterfall. Damien gleefully writhed about in the puddle that had been formed, and he clutched his stomach, feeling incredibly bloated. It gurgled loudly. Then something caused Damien to suddenly widen his eyes, and take short, shallow breaths. The voice laughed.
“You can feel it, can’t you Damien? Tell everyone what you’re feeling right now.”
Damien sat motionless, almost shellshocked. Then, a wide smile stretched across his face.
“I think I can feel it! It’s like this…this supernova inside of me that…Gah! My legs!”
He held on tightly to his thighs and winced in pain. Danny could see a mixture of fear and excitement on the boy’s face. Damien gasped and let out a shocked laugh.
“They’re growing!”
His legs slowly began to elongate. He was getting taller and taller. His thighs widened with solid muscle under his grip. Once his calves peeked out from under his jumpsuit, he noticed they were now covered in a layer of dark hair. His feet swelled to match, reaching the size of Mr Blake’s in no time. The rest of him remained completely unchanged, but his legs had sprouted into those of a burly man. He tried to stand up, and nearly lost balance as he adapted to his new height. Mr Blake stepped back and, along with everyone else, simply watched on.
Once his legs stopped growing, his attention quickly moved onto his ass as it tingled, sending shivers across his body. He bent over to get a good view, and grinned as he watched it balloon, stretching out into a bubble butt that would even put Zach’s to shame. Damien squeezed his cheeks and let out a moan.
“Damn, they’re so sensitive now. Just one good pinch and—“ he moaned as he pressed even harder down on his ass. Danny could see a small stream of cum run down the boy’s leg and drip to the floor. He noticed Damien’s change seemed more incremental than Mr Blake’s, possibly for the entertainment of the voice of the speaker, who was quietly laughing away as Damien grew and grew.
“It’s still going!” Damien yelled excitedly.
His once loose sleeves quickly became tightly wrapped around a bulging pair of arms. He sensuously rubbed his biceps, feeling them get bigger by the second. The creaking of the jumpsuit fabric was music to his ears, but the outfit was starting to limit his movement.
“Crap, better take this off quickly,” he muttered to himself, only for the voice to laugh even louder. As the boy unzipped his jumpsuit, he stopped mid-way, realising his skinny chest had sprouted an eight pack. Two pecs had just begun rising like two loafs of bread in an oven, taking up more space inside his already constrictive outfit.
“Oh God, everywhere feels so tight,” he said, slightly more panicky, as a thick patch of chest hair had begun to darken his torso. He tried to pull the zip all the way down, but it was stuck. He pulled as hard as he could, only for the fastener to fly off the jumpsuit.
“Shit! Oh God, my back!” he groaned as his shoulders forcefully broadened, thickening with muscle. His now huge traps left the jumpsuit at near breaking point. The voice cackled away as Damien tried with all of his might to get out of the skintight jumpsuit. The fabric began to dig into his body. He tried to tear it off, but to no avail.
“Sir! Help me!” he cried out to Mr Blake who, after spending a few moments taking in the sight of the grown student before him, walked forward and easily tore the zip apart, allowing Damien’s chest to push out into the open. Damien seized the chance and slithered the rest of his body out, breathing deeply with great relief at the feeling of freedom his body now had. He gazed upon his physique, stupefied at how much it had changed in such a short time. His arms were coated with a generous portion of hair, and thick black bushes began to sprout out from his armpits. He could smell the rampant pheromones in his sweat, growing hornier with each huff of his pits. He looked disappointed that his hardon hadn’t grown at all, but before he could say another word the voice spoke.
“Don’t worry. Two more changes still need to be made.”
And in an instant Damien’s cock pulsed, swelling to enormous proportions. He gripped it tight and moaned as he felt his shaft thicken beneath his palms. He had a dumb smile on his face, and his eyes were closed. His balls became heavy and full under his manhood. Just like Mr Blake, his member began leaking heaps of precum.
“Thank you,” he exhaled.
“Just one more thing to go…” the voice giggled. Damien then felt his face grow incredibly hot. Running his fingers along his jaw, he could feel the bones shift as his face grew more masculine. His neck widened as an Adam’s apple began to push outwards.
“I feel so—my voice! It’s changed as well!”
“Everything about you will change.”
“Everything?”
“Yes. You will become a beast. You will lose control of your thoughts, until theirs is just one thing you need to do. One thing you HAVE to do.”
“But—“
“Shhhhh. Don’t fight it. Just let it finish.”
“Okay…ohhkay…ohhhhh…”
Danny could see Damien’s gaze slowly turn blank, and his breathing become deep and grunt-like, almost exactly like Mr Blake’s. A short beard grew along his face, and his eyebrows thickened. Eventually, once it was done, he looked nothing like the Damien from a few minutes ago. He was as tall as his teacher, and just as well-endowed.
“Now, who wants to join them?” the voice asked.
Damien’s primal urge to find someone to fuck quickly took over, and it wasn’t long before he and Mr Blake were chasing the students across the room yet again, plunging the group into a familiar chaos. The shrieks returned, the heavy footsteps that rattled the walls could be felt, and Danny felt even more hopeless than before. He and the others continued their endeavour to open the door.
However, a pair of footsteps grew louder and louder, and they turned around to see Mr Blake charging towards them, his eyes wide with lust. Danny clamped his eyes shut and accepted his fate until he felt the door suddenly swing open and a pair of hands drag him to the other side. Chris and Zach fell in too with a few others, and they looked up to see a middle-aged man in a lab coat stand valiantly over them, pointing a dart gun straight at the charging Mr Blake. He pulled the trigger, sending a dart straight into Mr Blake’s shoulder, who immediately tripped on his feet and collapsed against the door frame. The man then reached out and tried to pull the teacher through the door.
“Don’t just sit there, help me!”
Danny recognised that voice. They all did. It’s the voice from the speakers. Everyone obeyed without question and pulled Mr Blake through. Danny could see the musclebeast Damien with two more students in each of his hands before the man slammed the door shut and locked it. The sounds of the room were no more, and they all sat breathless and fearful over the almost unconscious Mr Blake. The man took a few breaths before speaking again.
“Before you say anything, he’ll be fine. He’s starting to change back now.”
And he was right. The dart caused Mr Blake to gradually shrink back to his original size, his body hair shedding and falling to the floor. He grabbed his head, as if experiencing a massive hangover. After almost a minute he was back to his younger, 20 year-old self. His body was shaking with both adrenaline and the coldness of the room. His cock eventually softened. He was too much in shock to speak. They all were.
But they needed answers. Now.
