"Shut up!" Troy ashamed yelled to his classmates. "Oh fuck!" He was struggling with his boner as the kids laughed at his humiliation. "Mr Mendes, how do I make it soft?!"
"Don't worry, your erections are completely normal because your body is getting used to its hormones." Mr Mendes smiled. "I wonder how is Liam dealing with that."
Meanwhile in the bathroom, some moans and grunts could be heard from a stall. All the boys that entered the bathroom felt awkward of hearing that and seeing a couple of big manly feet in there.
"I can see that we have already three couples of young men in class." Mr Mendes said. "So, why not getting another one. Who wants to be next?"
"Dean and Marco" Troy said almost immediately and saw at his friends who looked scared after hearing that. "I saw you were laughing at me, assholes. So, it's time for a little revenge!"
Mr Mendes knew that Dean and Marco were Troy's best friends, so he thought it wasn't a bad idea. He looked through his magic book and used a spell on them.
"It's done!" Mr Mendes said. "Dean, Marco. Can you come here next to Troy?"
Both kids reluctantly obeyed and stayed next to his friend. However, in Troy's actual condition, he looked more like his older brother than his friend.
"You look so small!" Troy told them.
"And you look like a monkey!" Marco replied.
"And smells like one too!" Dean added and Troy blushed after hearing it. He lift an arm and sniffed his armpit. He felt ashamed it was true and that he has a big hairy bush in there.
"Yeah?!" Troy replied. "I won't make too much fun of that because you are going to get it too soon!"
The kids looked each other worried, they knew what would happen from seeing the other guys growing. Marco was the first to show any signs. His body seemed flushed, as if the room had suddenly risen fifty degrees. Marco began to strip off until he revealed his tented cartoon boxers. All his classmates burst into laughter.
Embarrassed Marco turned redder, yet Dean expressed his sympathy. The sympathy to shock quickly as Marco’s legs and arms grew longer and the hair on them darkened to a deep black. The growth raced up to his boxers which seemed smaller. Up from his boxers a line of hair grew meeting the hair that had just started growing around his nipples.
“Holy shit Dean!! LoOK aT YouR Face!!” Marco exclaimed as his cracking voice dropped down to a baritone. Dean hadn’t realized how hot he had been getting.
However Marco’s comment had brought him to the realization that he too was changing. Quickly he pulled off his clothes, only to notice his briefs bulging with an erection.
“Damn! This is quite strange; I never would have thought I would get my first erection like this. Do you think the same?” Dean said in his already deepened voice.
“Yeah, umm your face though.” Marco hinted. Dean felt his cheeks to see what he meant, yet was surprised to find a heavy layer of stubble covering them. Just then the world seemed to spin for them both as they hit their final growth spurt. However that didn’t mean the changes had finished.
Next both boys’ penises began to move. The growth had thrown both Dean and Marco into a look of ecstasy and disbelief as their members grew past the point of manhood and straight into monstrous cockhood. Their testicles had also enlarged. Marco seemed to be sporting a full girth branch with two lemons. Dean was smuggling a larger branch with two full grown prize winning limes.
The third piece then came into play. Both boys were left in sexual moans of pleasure as their new equipment flooded their systems with testosterone. These moans however began to grow deeper and more sexual with the seconds. Both boys had started to bulk up a bit. Marco’s started with his chest, which pushed forward into two firm, strong pecs. To compensate his lats pulled his shoulders back while straightening his posture. His quads then bulged out with his lower legs following. His shoulders broadened as his delts created a nice rounded shape. His abs pushed out then flattened into a very sexy six-pack. His biceps finished off bulging into thick cannons. Afterwords his body settled into a professional wrestler’s build. Dean started differently, yet in the end he also had a professional wrestler’s build.
The Final stage then hit. Both boys, now men, were exhausted, but that lasted only a few minutes as their entire bodies had the feeling of ants crawling up them. Marco’s hair darkened to a midnight black as it spread from his near fatal looking boxers to his legs and chest covering him in a sexy, thin coat. Dean’s hair darkened to a dirty blond as it covered him in a quite similar coat. Lastly it took start on their brains, raising bother their sex drive and their endurance. Having just grown nearly eight years in one hour both men were extremely horney, and needed to release. So, they suddenly fell on the ground and jacked off their manhoods through the constricted fabric of their tiny underwears.
