Max was trying to recall what he studied in Health class. What were all the effects of testosterone on the human body when he realized something. "Hey! You're not suggesting this, so you'll be the only pretty boy in Nick's boy band, are you?"
"...Maybe..." Ricky said sheepishly. Max gave him a look, but he really couldn't blame his brother. The reason why he got the Chronivac was to look different from his twin, after all. Still, either way, the idea was interesting enough for Max to do it regardless. So, he brought up the Chronivac again and gave both Nick and Greg a 50% boost in testosterone. Then on a whim, Max increased Nick's attraction to muscular men.
"Well, Nick, after this, no one is going to call you girly anymore."
--------------------------------
When the changes started to occur, neither of the men noticed. Both of them were too busy focusing on each other and the pleasure they were feeling. Nick was too distracted thrusting to notice that his thrusts were slowly getting stronger. All his muscles were slowly growing. His once lean body, sculpted for vanity, was thickening with strength. His face was losing that pretty boy look and was now becoming more masculine with a smattering of stubble adorning his chin. He didn't look like a boy band member anymore, or at least one that appealed to the typical teen girl demographic, but an up-and-coming musical heartthrob.
Though Nick wasn't in a position to care about this, all he cared about was reaching orgasm. Like a mad man, Nick trusted wildly into Greg, just so hungry for that release. He trusts and thrusts until...
"Ahhh!"
Both men collapsed onto the bed after that intense orgasm. Nick was still reeling as he collected his thoughts but still not noticing what had happened to the both of them. He finally did it! He finally lost his virginity! And to another man no less! Nick initially didn't want this to be a regular thing, he still wasn't exactly queer after all, but after that intense orgasm, he was having second thoughts. In fact, he felt ready to go another round, which was odd because he read that people needed to wait a certain amount of time before they had sex again. It seems like the boost in testosterone had a side effect of skipping their refractory period. In fact...
"Well, that was fun," Said a voice that Nick did not recognize until he realized it was Greg's voice but in a deeper tone for some reason. Looking up, Greg did not look like he did a couple of minutes ago. His body was no longer that of a lean running back but now at least starting to approach Gabe's body. His now broad pecs had a smattering of chest hair now. His face was now devilishly handsome with a goatee and cocky smile. "I think it's time I returned the favor. It's your turn."
Nick gulped, nervous but also strangely aroused. He had no idea what happened to Greg or himself, but he was starting to become too aroused to care.
-----------------------------
Back to Max, he soon realized that neither Greg nor Nick would have clothes that would fit when they were done. He decided to tailor-made their pants and underwear to fit them, but they would have to go without shirts, at least for the time being.
"Come on, Max! Hurry up, or else we'll miss the party," Max's twin yelled at him.
"Alright, alright, I'm going," Max replied. It was probably best to not make any more changes until they've arrived at the party. He wanted to at least talk to Nick as he was now.
