"So boys, I'm going to need you to strip down to nothing. I know it may be embarrassing to be naked in front of your friend, but to make all the measurements you must be naked. Anyway, if your test is successful, you two will see each other naked anyways." The doctor instructed sinisterly.
"What exactly are we testing anyways?" They asked in unison while stripping down.
"Can't say, it would ruin the experiment. Okay, so you first." He said looking at Rian. Quickly the doctor pulled out a tailors measuring tape and measured Rian all over including his penis. Then he measured his height and weight before moving on to do the same thing to Bradly.
After the measurements her took their clothes, dropped two black boxers with a two button fly, and left. The boys put on the boxers to find out that they were so tight they hid nothing. Seconds later the doctor came back in and gave each boy a pill and a black liquid that tasted like apple juice.
The boys looked around to find the room like a prison cell with mirror walls. There was to cots with built in pillows and no blankets, a toilet, and a sink. Both boys sat on the edge of the cots and stared at one another silently.
"So. . . any change?" Bradly asked bored.
"No, you?" Rian said equally bored.
"Ditto. Sheesh, at least they could have left us with some board games. I mean it feels like a prison in here." Bradly complained.
Suddenly the boys felt a sharp pain in their groins as if they had been kicked there by a horse. They laid still cringing in pain as their bodies started to change. Rian was the first to notice what had happened. As he felt around his boxers he realized that his balls had grown to the point of being pinched by the seems in the boxer. Realizing that the boxers won't help much he took them off, and quickly the pain was gone. However the changes were not, they continued even faster. Bradly, seeing what Rian had done, copied to feel instant in his groin. Both stood up and stared at each other. quickly looks of terror spread across their faces as they realized their bodies were paralyzed. Quickly each shot up in height. Rian went to 5'2, then 5'5, then to 6'2 in a matter of seconds. Bradly shot up to 5'1, then to 5'7, stopping at 5'11. Next was their muscles as they began to swell with mass. Both looked like muscular high school students with small dicks, but that was quickly changed. Their dicks grew to 6 1/2 inches long, and about 4 inches in girth. Then came the hair. Bradly's legs quickly became covered in light blond hair that started at his ankles and moved to meet his pubic hair which started to crawl up the middle of his abs to meet his new chest hair. His arms grew a thick coat of hair, and his face grew a full blond beard. The same thing happened to Rian only seconds after Bradly. Finally they felt a dizzying feeling as their baby fat disappeared creating a adult masculine appearance.
Following the final touches both "boys" gained control of their bodies. Quickly they began to inspect their new bodies, before turning to the other.
"Holy crap Rian, you, and me look like adults now!" Bradly said in a rich baritone voice.
"Damn, even our voices are different. This feels amazing!" Rian expressed in his deep sounding tenor.
"Wait, what would our parents say?" Bradly though of quickly.
"Not to worry men. For your successful test we're going to pay you a monthly $1,000 dollars, give you free housing in an apartment, and pay for free schooling for the next 20 years. But first we need you each to take one of these pills." The Doctor said over the intercom as a drawer with to pills slid out.
Both men swallowed the pills which began their effects immediately. Both Rian's and Bradly's bodies began to jack off into the bin. Being young they quickly cummed as almost a gallon of sperm filled the drawer. However, neither man felt the nano chip adding information to their brains.
