Hearing the knock Simon looked over to the door. Trying to make his voice sound more high pitched "Who is it?"
"Ricky. We have that school project to work on, remember. Let me in."
Now that Simon thought about it, Ricky was actually kind of cute. And that gave him an idea. Simon got up and stood beside the door, with his back up against the wall. "It's open." The door swung open and Ricky walked in. Simon moved quickly and scooped up his friend in a bear hug, his now older body not having any trouble subduing the young teen.
Ricky still thrashed, fearing the hairy naked man that had just grabbed him. "Who are you? Where's Simon? HELP!"
Simon moved one hand over his friend's mouth. "Shut up, dude. It's me Simon. I've decided to have a little fun with you though." He pushed his friend on the floor, grabbed a nearby shirt and used it to ties his friend up.
Simon moved around in front of Ricky, and crouched down, letting his hairy cock dangle in front of his friend's face. Ricky looked away. "You can't be Simon."
"Oh I am. I got a program that can change people. I used it on myself. I think you'll like it too." Grabbing a pair of scissors he cut off his friend's clothes, leaving him trussed and naked on the floor. Simon walked over to the computer, and pointed the emitter at his friend on the floor. Entering the command to scan Ricky, Simon set to work on the bars.
"What are you going to do to me." Ricky was looking at the machine with panic in his eyes.
"That's going to be a surprise for you." Checking the bars, Simon left the GBS bar alone. "Let's see.. age. You always liked that you were older than me. I'm 20 now, so we'll make you 21. 6', you can be older, but I want to be taller." Indeed, Simon's thick hairy cock was stirring to life. "I think I'll make you less hairy than me, but you should still have some. Slightly above average hair. Swimmer's build, just like me. Still don't get this one, let's try the other option." Sliding the one bar to circumsized, Simon looked the screen over. "Anything I forgot?" He clicked through the confirmation boxes. The countdown began and Simon turned to look at his friend.
Already some changes were visible on his friend. Ricky's blond pubic bush had thickened slightly, his balls dropped, growing a fine layer of blond hair, his cock also got a little longer. Ricky's body began to stretch, his shoulders becoming broader has he began to age. Blond hairs grew on Ricky's legs and arms, a few more growing under his arms.
As muscle began to form, Ricky's pubic bush grew up to his belly button, running between his slowly firming six pack. His pecs began to swell with new muscle as fine blond hairs pushed out from around his nipples and the middle of his chest.
Ricky began to pant heavily, his body stretching until it reached his full height, his genitals swelled to full grown proportions, he had an average six inches, but his balls were like eggs. As his muscles grew and became more defined his body hair began to grow out. The hair on his abs spread out, covering them in a nice pelt, the hair on his chest following suit. The hair on his limbs grew out and thickened. And a few days of stubble appeared on his squaring jaw and more manly face. His new body was athletic, and while not as hairy as Simon, he still had a descent pelt of blond hair covering him. As the changes stopped Simon went over to his friend. "Well?"
"I feel great.. but.. damn, dude. I didn't notice at first, but you are hot." His cock stirred in response to his hairy friend. "Why not untie me, and we can have some fun?"
