You were in a state of disbelief. Ken just suddenly shot up nearly half a foot in height! Your eyes still on the boy as you can hear him say, "Yeah... I get it!" He grins cutely, still having to look up at you, but if another of those beams came along, there was no telling just how much longer he would be the one looking up! "Of course! It all makes sense now!" Ken chuckled.
"Y-Yeah? Well, what is it?" You finally managed to ask once you got over the shock of the kid growing before your very eyes! It seems he knew why all this was happening, and damn it all, you wanted to know too!
"I must be some kind of... Experiment! Yeah! They're gonna test these lights on me, and you're a... Uhm..." Ken stopped his brilliance for a moment to stop and think of what the word was. As he did, you couldn't help noticing he still had a bit of a semi in his pants... It looked like it was wearing down, for now. "Variable!" Ken said suddenly, snapping you from your trance! "Yeah! You're a variable to see how I act when I have someone bigger than me to play with!"
"Wha?" You reply in disbelief. "Experiment? I never agreed to any of this!" Ken just looks back at you with a slight frown, but you couldn't quite tell if it was because he was sad or if he was upset that you weren't being helpful!
"Well we're stuck here, so we better make the most of it!" Ken snapped, folding his arms over his chest and turning to head back to the TV. You just sigh and rub your head, wondering how you're going to get out of this mess...
Suddenly, you hear the sirens going off again! Your start glancing around the room, your head whipping around like a lawn sprinkler in overdrive! You could hear a rumble, as another light suddenly engulfed Ken, this one red in color! You started to run over to him to make sure it wasn't hurting him, but as you soon found out, it was doing something even better!
Ken's back, which was still turned to you, started stretching out farther and farther, his once lithe frame suddenly putting on some muscle! He was growing wider by the second, his shoulders looking broad and powerful, each of them already nearly the size of softballs! His little tanktop was stretching even higher now, showing off the bottom of a set of abs! Each of them like smoothed out rocks that were slowly being carved into his body and pushing out further! You could hear a soft moan escaping his lips, his whole body starting to throb as his pecs were surging with power, each of them developing into a meaty slab that dragged down the collar of his shirt. Getting so massive that they poked out from either ends of the cloth! Ken couldn't resist giving them a squeeze, which only made him moan even louder! His thighs got closer together as they expanded too, driving his shorts up a little higher and filling them out, high thighs tightly stuffed inside. There was hardly enough room to even fit a penny in! His calves balled up as well, pushing out huger until they were like melons on his still growing body! His bare feet stretched farther across the cold floor, each big, fat toe wriggling as it was moved along. As you rounded around him, you spotted possibly most embarrassing of all was that the bulge in his pants was getting bigger too! It started to tent out again, and grew in quick, sudden surges! You gulped, a bit jealous as you saw that he was practically as "big" as you were!
As the light finally went out, you could hear Ken panting heavily, his whole body a little red as blood rushed all over, feeding his pulsating muscles. Sweat was beading down his body like bullets. Your jaw had dropped as this kid, who was once smaller and scrawnier than you, was now about chin-high, and had muscles of a pro bodybuilder!
A sound echoed in the room, from one source! You gazed to look at the TV, but it wasn't coming from there... No, that voice, that deepened, cocky tone of voice was coming from Ken! Your head snapped forward as you looked at him, only to see him looking up at you with a devilish little grin on his face! You didn't know if it was the muscles or that beam, but his whole demeanor seemed to change!
Ken decided that...
