Feeling that nobody was there, Mark stripped himself of his singlet and found his briefs were wet. He looked from side to side before he slowly brought down his underwear. As he did, his huge dick sprung out. Mark was almost entranced and intrigued by it--he was wondering how it got so big. Precum continued to leak from its tip, even though he wasn't even doing anything.
Ty was amused at Mark's interest in his bulge. He glanced at Mark's stained green singlet. He grinned as he got an idea for a spell, whispering, "Green isn't just a school color, Mark. Why don't you Hulk out?" Sure enough, as he finished speaking, Mark started changing.
It started with his dick. Mark's widened a bit when he saw his cock start to reach a greenish tint. "What the fuck..." He muttered, confused.
A tingling sensation started to form in his dick. Mark grabbed it and started rubbing it, which to his dismay started to stiffen. Ty nearly snickered.
It was then that the sensation spread to his whole body. But rather than tingling, it had become more of a pleasureful feeling. Mark groaned as his eyes had become a bright green. "Woah..." he trailed off. Ty smirked.
The world almost started to spin around Mark, as he started to sweat. Then his already relatively-muscular body became even more muscular.
He moaned as his muscles started to grow and expand. His pecs pushed outward while his abs started to become more cut and defined. His calves started to swell as well, and by then the color green had started to creep up from his crotch. Mark punched a locker and managed to leave a dent in it, surprisingly.
His breathing became loud and heavy as mutters of "Shit" and "This feels good" fill the air.
Just as all of his skin had become an emerald green, his hair a much darker shade, his growth had stopped. Where a wrestling captain once stood was a huge 8-foot tall green Hulk. Not to mention that his cock was now 26" and standing erect.
"Oh fuck," he said, still panting from the transformation.
Dustin then came up next to Ty and asked, "Hey what happ..." But he trailed off. "Oh. That's what happened. Woah man his cock is huge."
Ty cracked a smile. "I know."
