"I can't just hit Collin with the same color," Quantrain muttered to himself, low enough so not as to be heard by the two horny boys. "After all, the whole point of this experiment is to see the differences between the versions, and what better way to see those differences in action than to apply two of them to a pair of boys that were already involved with each other?" He chuckled lightly as he dipped the tip of one of the darts, coating it in the yellow formula. "Because," he explained aloud to his nonexistent audience, "yellow is the most logical choice, since it compliments green, and also since with both versions, the affected boy will experience a significant change when he orgasms."
Quantrain looked out again, noticing that Collin and Luke were now making out fairly vigorously, both still shirtless and wearing their pants and boxers, respectively. Loading the dart into the tip of the gun, the doctor brought the opposite end to his mouth, carefully threading the long slender gun through one of the cracks in the air vent through which he was watching the scene unfold before him. Blowing hard, the dart flew from the wall straight at Collin, hitting him on the side of his stomach. The young teen was far too involved with his boyfriend to even notice the prick, and after resting in his side for a few seconds, the dart fell to the ground. But the deed had been done; the formula, yellow version, was in his bloodstream, and since that was a more direct application than Luke's had been, Quantrain reasoned that the effects should manifest themselves much more quickly.
And he was right. Collin instantly started inching upwards, not noticing, at least initially, that his khakis were becoming ever so tighter. Of course, it's hard to notice those things when you have your hands wrapped around a pulsating cock oozing with pre-cum, as the redhead currently found himself doing. "Holy shit," Collin exclaimed as he felt the girth of Luke's meat. "Since when have you been so big?"
"I-- I don't know!" Luke responded. As the two boys turned slightly, Quantrain finally got a sight of the massive member to which they were referring. It was indeed a sight, over a foot long and with the thickness of the wide end of a baseball bat. Collin could barely just fit one hand around its girth, and he began to move it up and down the shaft, his other hand now traveling inside his own pants.
"Hmm," Quantrain murmured, repressing a moan that was welling up inside him from seeing this incredible specimen of boyhood. "I suppose that probably is a new development. After all, I don't think that he'd ever leave his bedroom if he had a cock that big. I suppose there are some side effects of the various versions of the formulas that I have yet to discover. How exciting!"
He grabbed his small notepad out of his pocket and jotted this down. As he turned back up to look at the boys, he was slightly surprised to see that Collin was now a full foot taller than before. His pants were now much too tight, starting to split at the seams, and the fourteen year old was starting to feel uncomfortable due to this, though it didn't keep him from continuing to jack off his now smaller-but-older boyfriend. His hand fit comfortably now around Luke's cock, and was now nearly soaked with the torrents of pre streaming from the tip.
"Ughhh, what's happening to us?" Collin moaned, a nervousness evident in his face but an intense horniness beating it out. Fed up with how constricted he was feeling, he grabbed his pants and boxers with his free hand and pulled at them hard, yanking them clean off with one smooth motion, then ripped off Luke's boxers immediately afterwards, leaving both boys completely nude and rock-hard. Collin's own cock was clearly hard, and large due to his overall growth, but it didn't look as out-of-place as Luke's did, fitting in nicely with his frame, now approaching seven feet tall. Also, unlike his boyfriend, he didn't seem to be releasing any pre at all, though Quantrain figured that was more due to his own biology, since he seemed to be as intensely aroused as Luke did. Luke seemed to jump at the chance to grab hold of Collin's cock, and he stroked the growing member, quickly graining speed.
Both boys now were jerking each other off with more passion and intensity than Quantrain had ever seen. Collin seemed to be getting the worse deal of the two, as due to his now two-foot height advantage, he had to stretch his arm out completely and bend down to keep Luke's cock in hand, and wasn't able to get quite the range of motion that Luke could get. Still, Luke didn't seem to mind, as his body seemed to be tensing up.
"Fuck!" Luke exclaimed, and Quantrain braced himself for what he was about to see. "I'm-- I'm about to--" Before he could finish his sentence, his cock erupted with a huge rope-like shot of cum, shooting straight up and hitting Collin in the chin and ear. As he continued to cum, his body suddenly began to get bigger, with surges of growth occurring in rhythm with his cum shots. He leaned against the wall, banging his hip against his desk and knocking his lamp to the floor.
After four, five, six shots, his cock finally ended its production, and he fell back against the bed, not even noticing that his head had hit against the nine-foot-tall ceiling and dented it slightly. "Oh well, I suppose I should alert the maintenance department," Quantrain chuckled to himself. "But first, let's see how Collin does."
Being soaked with Luke's seed seemed to only add fuel to Collin's already blazing fire, and he too seemed to be close to orgasm, as close as his head was to the ceiling (that is, pretty damn close). Both boys were now close to the same size, and Collin had taken his own cock back in his hand, stroking it fiercely as he wrapped his thighs around Luke's stomach and his ass brushed against Luke's still-hard and dripping-wet cock, causing his toes to curl. Without warning, Collin thrusted his hips forward and he began to cum as well, but unlike Luke, he started to shrink as he shot his load up Luke's chest, hitting him in the face and soaking his hair. As he shrunk, the loads got smaller, until finally he was back to his own normal height, sitting on the stomach of Luke, who now towered over him.
Both boys were panting, still lost in the afterglow of the most intense orgasms of their young lives (at least, so far). "Shit," Luke finally said in between breaths, "that was incredible."
Collin seemed to be just as amazed but also slightly worried. "How-- why-- ?" He couldn't say more than one word at a time, and just shook his head, trying to comprehend what had just happened.
"Well," Quantrain said, "I'd say that the first stage of the experiment is a rousing success." He thought about staying around and seeing how the boys handled the aftermath, but he needed to get back to his office and get prepared for tomorrow. "And besides," he thought to himself, "I've got the footage from the security camera in their room to, um, peruse."
