"So... where were we? Ah, yes... Puberty. Puberty is where..."
Practically everyone in the room couldn't hold it in anymore and moaned loudly--their bodies were aging not one but two whole years. If they hadn't noticed what was happening before, they were certainly aware of it now. The sound of clothes and shoes ripping was unmistakable. More than a few of Ty's classmates hit incredible growth spurts and literally stretched out of their clothes. One or two, thanks to their genetic disposition, really bulked up into huge, muscular teenagers. There was no way--and no reason--to hide anymore.
"Ooooh yeeeah..." one of them groaned as he felt his body mature more in seconds. His mind was swimming in sensations that were overtly sensual and sexual.
"Maaaan... this is great," another said tearing off his tattered shirt and rubbing his hands all over his hard-toned 20-year-old body.
Jason was jacking off. He never felt this great. He was seated shirtless with his eyes closed and had opened his pants to let out his cock. He didn't care anymore; he was too horny. His balls have been churning semen for a good five years and he needed his release--NOW. And apparently so did the other kids as they took their cue from Jason and began unbuttoning their pants and fondling their packages through their bulging underwear.
But Ty had his attention elsewhere; he had his eye on Mr. Bretmon who still had his face behind the book and had no clue of what was unfolding right in front of him. Ty never considered Mr. Bretmon to be a handsome man whose mean attitude was a real turn-off. But as Ty watched the 40-year-old man getting younger by a good 10 years, even he had to admit that Mr. Bretmon had been a hunky stud all along albeit the 38" beer-belly. The teacher's hair grew shorter but thicker. Ty couldn't make out the wrinkles on Mr. Bretmon's face anymore and he was glad to see that his teacher had began to lose a tremendous amount of weight, probably 50 lbs of fat for starters. Too bad he's seated behind that desk, thought Ty. He would have wanted to see how big his dick would have gotten so far.
Mr. Bretmon was getting terribly peeved off at all the noise. "Are you all asking for detention? I know puberty isn't a subject you're comfortable with but... but..." Putting down the book, Mr. Bretmon looked up and, for the first time, he was speechless.
The entire class erupted in a euphoric roar, "Ooooooohh!!! Fuuuuck!" The room filled with the powerful aroma of young men in heat. For those who were beating off, they felt their cocks expand and lengthen right in their very hands. For those who weren't, they totally lost their inhibitions and decided to join in the fun as well.
Mr. Bretmon was shocked. There were clothes all over the floor. The last time he saw his students they were normal 14, 15-year-old teenagers, but what he had in the room were hot and horny 19, 20-year-olds with built bodies pumping their engorged pricks and he saw them get older by a year. They were all excellent specimens of manhood in the room. All of them different; all of them beautiful.
"What... what the hell's happening here? Stop what you're doing!" he shouted but no one was listening. He stood up from behind the desk to get their attention and when he did, his pants fell to the floor. He looked down and wondered if somebody just played a prank on him. It was only then he realized how loose his shirt was and how his beer-induced stomach had all but disappeared. He lifted his shirt and gasped at seeing his six-pack abs forming right on his torso and his legs tightening up with shredded muscles. He continued pulling at it till it passed his pecs and marveled at how huge and ripped they had become. Even at 25 (the age he was now), they were never this size. Then something caught his attention, something moving--it was his package, or was it? It couldn't have been... it was too big and it was stretching his white briefs to an obscene degree. Mr. Bretmon threw off his shirt and ripped off his briefs.
"Oh. Shit." There was his cock... and it was massive--at least 12" long and 7" around--and at every heartbeat, it slowly pumped up with blood becoming more and more erect. He was mesmerized by it.
He couldn't believe it but he was young again. He regained the athletic body he lost years ago but with a lot of enhancements: his muscles were thicker, his cuts were deeper, and obviously, his prick was bigger. But there was one thought in his head overriding all other things: he wanted to CUM. His body craved for it; his cock cried out for it. He sat down on his desk and was about to service himself when Ty appeared in front of him with a great big smile asking, "Do you need help with that, stud?"
Mr. Bretmon didn't get a chance to respond; Ty just went for his cock and amazingly, the entire thing went into the teen's mouth. "Noooo..." the teacher screamed in protest, his last gasp for dignity, but as soon as Ty's tongue massaged his glans, he went ballistic. "Yeaaaah... Suck me harder you bastard! Oh you little fucker, that's it... uuuunnngggh.... uunngh... nyaaaaaa..."
Suddenly, he remembered where he was and saw his entire class was in disarray. While a few of his now adult students were jacking off on their own, the rest took the initiative to form into groups. There were circle jerks, there were couples on the floor 69ing each other, and there were threesome and even foursome fuckfests.
He watched the debauchery in awe. He wanted to tell them to stop but couldn't. The smell of sex was heavy in the air and with Ty bobbing up and down his dilated dick, he couldn't get the words out. Strangely, no one seemed to have achieved orgasm yet and that just made everyone hornier and crazier.
"Fuck..." he whispered aloud relishing the sensations shooting through his body, "this is like going through puberty again..."
The moment he said that, Mr. Bretmon as did some of his students let out a yell, "Hooooleeeeee!!!!" His body began to morph yet again this time into a 20-year-old college heavyweight bodybuilder with a crewcut while the class aged one more year. Ty thought he was going to gag when his teacher's cock ballooned inside his mouth but he quickly compensated for the new girth and length. This is it, Ty thought, a few more minutes of this then everyone's gonna get what they've been waiting 6 years for.
Ty reached into everyone's mind and telepathically connected them with each other. Suddenly, everyone could feel what his classmate was experiencing, every single sensation. Everyone wanted what everyone else wanted--TO CUM. If it were possible, their bodies were even better built and bigger than a few minutes ago and their lovemaking and fucking intensified. Precum and saliva was everywhere and on every one. Ever since the transformations began in class, Ty had been secretly suppressing their ability to ejaculate their loads and simultaneously pumping up their sexual fervor that was nearing its peak. Finally, Ty decided that it was time... time to let it all out.
With Ty maintaining his psychic rapport with his classmates, he wired everyone to Mr. Bretmon who was delirious over his blowjob of a lifetime. Ty dropped his control only over his teacher; he wanted to get this perfect.
Left to his own devices, Mr. Bretmon tried as much as possible to contain and prolong the pleasure on his own but was finding impossible to do so. Without Ty's interference, his body instinctively geared itself for its impending release: his baseball-sized nuts had drawn up to his body, he was taking in quicker breaths, and he was fucking Ty's hot mouth. The closer he came to shooting, so did his students; they were all synchronized to the former 40-year-old..
"Uuuuuuunggggh... shit... aaaah... my... God... uuuggh... aaaaah.... fuck... I... can't... uuuumph... nyaaaaahhh... yessss.... yessss..."
Then Mr. Bretmon stopped. He closed his eyes very tightly, drew in a deep intake of air, and screamed at the top of his lungs.
"AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHH!!!!!!!"
At that precise moment, the entire class joined in his raucous bellow and everyone started to cum AT THE SAME TIME. Thick ropes of jism flew all over the room; hungry asses and mouths were filled beyond capacity. The cum didn't want to stop flowing even after 10 shots. No one was left out of the titanic collective orgasm that lasted for minutes and ultimately took its toll on everyone, including Ty.
When it was all over, Ty and his college-aged classmates were drenched in semen. Some had collapsed on the floor, some were still seated barely holding on to consciousness. A few of them were trying to milk more semen from their friends to no avail. Mr. Bretmon himself was on lying on his back on the desk breathing heavily from utter exhaustion. Ty looked around and took pride in his handiwork.
Fuck this was great, he thought to himself, and there's still third period!
